# Admin Module - Untested Handlers/Source Files Analysis
## Executive Summary
This document provides a comprehensive analysis of untested source files in the admin module (`apps/api/src/modules/admin/`), with detailed code listings and testing patterns for reference.
**Analysis Date:** 2026-04-11
---
## 1. UNTESTED HANDLER FILES
### 1.1 reject-listing.handler.ts (Commands)
**Path:** `apps/api/src/modules/admin/application/commands/reject-listing/reject-listing.handler.ts`
**Status:** ❌ NO TEST FILE FOUND
#### Source Code:
```typescript
import { Inject } from '@nestjs/common';
import { CommandHandler, type EventBus, type ICommandHandler } from '@nestjs/cqrs';
import { LISTING_REPOSITORY, type IListingRepository } from '@modules/listings';
import { NotFoundException, ValidationException } from '@modules/shared';
import { ListingRejectedEvent } from '../../../domain/events/listing-rejected.event';
import { RejectListingCommand } from './reject-listing.command';
export interface RejectListingResult {
listingId: string;
status: string;
message: string;
}
@CommandHandler(RejectListingCommand)
export class RejectListingHandler implements ICommandHandler<RejectListingCommand> {
constructor(
@Inject(LISTING_REPOSITORY) private readonly listingRepo: IListingRepository,
private readonly eventBus: EventBus,
) {}
async execute(command: RejectListingCommand): Promise<RejectListingResult> {
const listing = await this.listingRepo.findById(command.listingId);
if (!listing) {
throw new NotFoundException('Listing không tồn tại');
}
if (listing.status !== 'PENDING_REVIEW') {
throw new ValidationException(
`Listing đang ở trạng thái ${listing.status}, chỉ có thể từ chối listing đang chờ duyệt`,
{ currentStatus: listing.status },
);
}
listing.reject(command.reason);
await this.listingRepo.update(listing);
this.eventBus.publish(
new ListingRejectedEvent(listing.id, command.adminId, command.reason),
);
return {
listingId: listing.id,
status: 'REJECTED',
message: 'Listing đã bị từ chối',
};
}
}
```
#### Associated Command Class:
```typescript
export class RejectListingCommand {
constructor(
public readonly listingId: string,
public readonly adminId: string,
public readonly reason: string,
) {}
}
```
#### Key Testing Points:
- ✅ Successfully rejects a PENDING_REVIEW listing
- ✅ Throws NotFoundException when listing doesn't exist
- ✅ Throws ValidationException when listing is not in PENDING_REVIEW status
- ✅ Calls listingRepo.update() exactly once
- ✅ Publishes ListingRejectedEvent with correct data
- ✅ Returns correct RejectListingResult with status 'REJECTED'
---
### 1.2 get-revenue-stats.handler.ts (Queries)
**Path:** `apps/api/src/modules/admin/application/queries/get-revenue-stats/get-revenue-stats.handler.ts`
**Status:** ❌ NO TEST FILE FOUND
#### Source Code:
```typescript
import { Inject } from '@nestjs/common';
import { QueryHandler, type IQueryHandler } from '@nestjs/cqrs';
import { ADMIN_QUERY_REPOSITORY, type IAdminQueryRepository, type RevenueStatsItem } from '../../../domain/repositories/admin-query.repository';
import { GetRevenueStatsQuery } from './get-revenue-stats.query';
@QueryHandler(GetRevenueStatsQuery)
export class GetRevenueStatsHandler implements IQueryHandler<GetRevenueStatsQuery> {
constructor(
@Inject(ADMIN_QUERY_REPOSITORY) private readonly adminQueryRepo: IAdminQueryRepository,
) {}
async execute(query: GetRevenueStatsQuery): Promise<RevenueStatsItem[]> {
return this.adminQueryRepo.getRevenueStats(query.startDate, query.endDate, query.groupBy);
}
}
```
#### Associated Query Class:
```typescript
export class GetRevenueStatsQuery {
constructor(
public readonly startDate: Date,
public readonly endDate: Date,
public readonly groupBy: 'day' | 'month' = 'month',
) {}
}
```
#### RevenueStatsItem Interface:
```typescript
export interface RevenueStatsItem {
period: string;
totalRevenue: bigint;
subscriptionRevenue: bigint;
listingFeeRevenue: bigint;
featuredListingRevenue: bigint;
transactionCount: number;
}
```
#### Key Testing Points:
- ✅ Returns RevenueStatsItem[] from repository
- ✅ Passes correct startDate, endDate, and groupBy parameters
- ✅ Calls adminQueryRepo.getRevenueStats() exactly once
- ✅ Supports both 'day' and 'month' groupBy values
- ✅ Default groupBy is 'month'
- ✅ Handles empty results (empty array)
---
### 1.3 user-deactivated.listener.ts (Listeners)
**Path:** `apps/api/src/modules/admin/application/listeners/user-deactivated.listener.ts`
**Status:** ❌ NO TEST FILE FOUND
#### Source Code:
```typescript
import { Injectable } from '@nestjs/common';
import { OnEvent } from '@nestjs/event-emitter';
import { type UserDeactivatedEvent } from '@modules/auth';
import { type LoggerService, type PrismaService } from '@modules/shared';
@Injectable()
export class UserDeactivatedListener {
constructor(
private readonly prisma: PrismaService,
private readonly logger: LoggerService,
) {}
@OnEvent('user.deactivated', { async: true })
async handle(event: UserDeactivatedEvent): Promise<void> {
this.logger.log(`Handling user.deactivated for user ${event.aggregateId}`, 'UserDeactivatedListener');
const deactivated = await this.prisma.listing.updateMany({
where: {
sellerId: event.aggregateId,
status: { in: ['ACTIVE', 'PENDING_REVIEW'] },
},
data: { status: 'EXPIRED' },
});
this.logger.log(
`Expired ${deactivated.count} listings for deactivated user ${event.aggregateId}`,
'UserDeactivatedListener',
);
}
}
```
#### Key Testing Points:
- ✅ Handles 'user.deactivated' event (async: true)
- ✅ Updates listings with status ACTIVE or PENDING_REVIEW to EXPIRED
- ✅ Only updates listings for the deactivated seller
- ✅ Logs initial event handling
- ✅ Logs number of expired listings after operation
- ✅ Returns void (Promise<void>)
- ✅ Handles case with 0 listings updated
- ✅ Handles case with multiple listings updated

## 2. EXISTING TEST FILES STRUCTURE & PATTERNS
### 2.1 Test File for Reference: approve-listing.handler.spec.ts
**Path:** `apps/api/src/modules/admin/application/__tests__/approve-listing.handler.spec.ts`
#### Complete Source Code:
```typescript
import { ListingEntity } from '@modules/listings/domain/entities/listing.entity';
import { type IListingRepository } from '@modules/listings/domain/repositories/listing.repository';
import { Price } from '@modules/listings/domain/value-objects/price.vo';
import { ApproveListingCommand } from '../commands/approve-listing/approve-listing.command';
import { ApproveListingHandler } from '../commands/approve-listing/approve-listing.handler';
function createPendingListing(id = 'listing-1'): ListingEntity {
const price = Price.create(1_000_000_000n).unwrap();
const listing = ListingEntity.createNew(
id, 'prop-1', 'seller-1', 'SALE', price, 100, 'agent-1',
);
listing.submitForReview();
listing.clearDomainEvents();
return listing;
}
describe('ApproveListingHandler', () => {
let handler: ApproveListingHandler;
let mockListingRepo: { [K in keyof IListingRepository]: ReturnType<typeof vi.fn> };
let mockEventBus: { publish: ReturnType<typeof vi.fn> };
beforeEach(() => {
mockListingRepo = {
findById: vi.fn(),
findByIdWithProperty: vi.fn(),
save: vi.fn(),
update: vi.fn(),
search: vi.fn(),
findByStatus: vi.fn(),
findBySellerId: vi.fn(),
};
mockEventBus = { publish: vi.fn() };
handler = new ApproveListingHandler(
mockListingRepo as any,
mockEventBus as any,
);
});
it('approves a pending listing successfully', async () => {
const listing = createPendingListing();
mockListingRepo.findById.mockResolvedValue(listing);
mockListingRepo.update.mockResolvedValue(undefined);
const command = new ApproveListingCommand('listing-1', 'admin-1', 'Looks good');
const result = await handler.execute(command);
expect(result.status).toBe('ACTIVE');
expect(result.listingId).toBe('listing-1');
expect(mockListingRepo.update).toHaveBeenCalledTimes(1);
expect(mockEventBus.publish).toHaveBeenCalled();
});
it('throws NotFoundException when listing does not exist', async () => {
mockListingRepo.findById.mockResolvedValue(null);
const command = new ApproveListingCommand('nonexistent', 'admin-1');
await expect(handler.execute(command)).rejects.toThrow('Listing không tồn tại');
});
it('throws ValidationException when listing is not pending review', async () => {
const price = Price.create(500_000_000n).unwrap();
const listing = ListingEntity.createNew(
'listing-1', 'prop-1', 'seller-1', 'SALE', price, 80,
);
listing.clearDomainEvents();
mockListingRepo.findById.mockResolvedValue(listing);
const command = new ApproveListingCommand('listing-1', 'admin-1');
await expect(handler.execute(command)).rejects.toThrow(/trạng thái/);
});
});
```
#### Key Patterns Used:
1. **Factory Function:** `createPendingListing()` creates test entities
2. **Mock Setup:** Typed mocks using `ReturnType<typeof vi.fn>`
3. **Initialization:** beforeEach() sets up fresh mocks for each test
4. **Entity Testing:** Uses actual domain entities with state transitions
5. **Domain Events:** Clears domain events after setup with `.clearDomainEvents()`
6. **Test Structure:**
- Happy path (success case)
- Error cases (NotFoundException, ValidationException)
- Side effect verification (repository calls, events published)
---
### 2.2 Listener Test Pattern: user-banned.listener.spec.ts
**Path:** `apps/api/src/modules/admin/application/__tests__/user-banned.listener.spec.ts`
#### Complete Source Code:
```typescript
import { UserBannedListener } from '../listeners/user-banned.listener';
describe('UserBannedListener', () => {
let listener: UserBannedListener;
let mockCommandBus: { execute: ReturnType<typeof vi.fn> };
let mockPrisma: {
listing: { updateMany: ReturnType<typeof vi.fn> };
user: { findUnique: ReturnType<typeof vi.fn> };
};
let mockLogger: { log: ReturnType<typeof vi.fn>; warn: ReturnType<typeof vi.fn> };
beforeEach(() => {
mockCommandBus = { execute: vi.fn().mockResolvedValue(undefined) };
mockPrisma = {
listing: { updateMany: vi.fn().mockResolvedValue({ count: 3 }) },
user: { findUnique: vi.fn() },
};
mockLogger = { log: vi.fn(), warn: vi.fn() };
listener = new UserBannedListener(
mockCommandBus as any,
mockPrisma as any,
mockLogger as any,
);
});
it('deactivates all user listings when banned', async () => {
mockPrisma.user.findUnique.mockResolvedValue({ id: 'user-1', email: 'user@example.com' });
await listener.handle({
aggregateId: 'user-1',
adminId: 'admin-1',
reason: 'Vi phạm chính sách',
eventName: 'user.banned',
occurredAt: new Date(),
});
expect(mockPrisma.listing.updateMany).toHaveBeenCalledWith({
where: {
sellerId: 'user-1',
status: { in: ['ACTIVE', 'PENDING_REVIEW', 'DRAFT'] },
},
data: { status: 'EXPIRED' },
});
});
it('notifies banned user via email', async () => {
mockPrisma.user.findUnique.mockResolvedValue({ id: 'user-1', email: 'user@example.com' });
await listener.handle({
aggregateId: 'user-1',
adminId: 'admin-1',
reason: 'Spam',
eventName: 'user.banned',
occurredAt: new Date(),
});
expect(mockCommandBus.execute).toHaveBeenCalledWith(
expect.objectContaining({
userId: 'user-1',
channel: 'EMAIL',
templateKey: 'user.banned',
templateData: { reason: 'Spam' },
}),
);
});
it('skips email notification when user has no email', async () => {
mockPrisma.user.findUnique.mockResolvedValue({ id: 'user-1', email: null });
await listener.handle({
aggregateId: 'user-1',
adminId: 'admin-1',
reason: 'Vi phạm',
eventName: 'user.banned',
occurredAt: new Date(),
});
expect(mockPrisma.listing.updateMany).toHaveBeenCalled();
expect(mockCommandBus.execute).not.toHaveBeenCalled();
});
});
```
#### Listener Test Patterns:
1. **Event Object Construction:** Manually create event with all properties
2. **Multiple Dependencies:** Mock CommandBus, Prisma, Logger
3. **Side Effects Testing:** Verify database calls and command execution
4. **Conditional Logic:** Test both happy path and edge cases (no email)
5. **Chained Operations:** Test interactions between multiple services
---
### 2.3 Query Handler Pattern: get-dashboard-stats.handler.spec.ts
**Path:** `apps/api/src/modules/admin/application/__tests__/get-dashboard-stats.handler.spec.ts`
#### Complete Source Code:
```typescript
import { type IAdminQueryRepository } from '../../domain/repositories/admin-query.repository';
import { GetDashboardStatsHandler } from '../queries/get-dashboard-stats/get-dashboard-stats.handler';
import { GetDashboardStatsQuery } from '../queries/get-dashboard-stats/get-dashboard-stats.query';
describe('GetDashboardStatsHandler', () => {
let handler: GetDashboardStatsHandler;
let mockAdminQueryRepo: { [K in keyof IAdminQueryRepository]: ReturnType<typeof vi.fn> };
beforeEach(() => {
mockAdminQueryRepo = {
getModerationQueue: vi.fn(),
getDashboardStats: vi.fn(),
getRevenueStats: vi.fn(),
getUsers: vi.fn(),
};
handler = new GetDashboardStatsHandler(mockAdminQueryRepo as any);
});
it('returns dashboard stats', async () => {
const stats = {
totalUsers: 150,
totalListings: 500,
activeListings: 200,
pendingModerationCount: 15,
totalAgents: 30,
verifiedAgents: 20,
totalTransactions: 50,
newUsersLast30Days: 25,
newListingsLast30Days: 40,
};
mockAdminQueryRepo.getDashboardStats.mockResolvedValue(stats);
const result = await handler.execute(new GetDashboardStatsQuery());
expect(result).toEqual(stats);
expect(mockAdminQueryRepo.getDashboardStats).toHaveBeenCalledTimes(1);
});
});
```
#### Query Handler Test Patterns:
1. **Simple Delegation:** Query handlers typically just delegate to repository
2. **Minimal Setup:** Mock only the repository
3. **Result Verification:** Check the returned data matches expectations
4. **Call Count:** Verify the repository method was called exactly once

## 3. HANDLER CODE FOR REFERENCE
### 3.1 Similar Handler: ban-user.handler.spec.ts
**Path:** `apps/api/src/modules/admin/application/__tests__/ban-user.handler.spec.ts`
#### Complete Source Code (for comparison to reject-listing):
```typescript
import { UserEntity } from '@modules/auth/domain/entities/user.entity';

## 4. INFRASTRUCTURE & REPOSITORY FILES (No tests required but provided for context)
### 4.1 prisma-admin-query.repository.ts
**Path:** `apps/api/src/modules/admin/infrastructure/repositories/prisma-admin-query.repository.ts`
**Status:** Infrastructure layer - Integration tests may be appropriate instead
**Note:** This is an implementation detail that delegates to more granular query functions. Consider integration tests instead of unit tests.
---
## 5. PRESENTATION LAYER FILES (No tests typically required)
### 5.1 admin.controller.ts
**Path:** `apps/api/src/modules/admin/presentation/controllers/admin.controller.ts`
**Status:** Controllers typically use E2E tests, not unit tests
**Note:** Controllers are tested via E2E/integration tests, not unit tests in this architecture.
---
## 6. TEST WRITING RECOMMENDATIONS
### For reject-listing.handler.spec.ts
Follow the pattern from `approve-listing.handler.spec.ts`:
1. Create helper function to build listing entities
2. Mock `IListingRepository` and `EventBus`
3. Test 3 scenarios:
- Successfully rejects pending listing → publishes event
- Throws when listing doesn't exist
- Throws when listing not in PENDING_REVIEW status
### For get-revenue-stats.handler.spec.ts
Follow the pattern from `get-dashboard-stats.handler.spec.ts`:
1. Mock `IAdminQueryRepository`
2. Test single scenario:
- Returns results from repository.getRevenueStats() call
3. Verify correct parameters passed:
- startDate, endDate, groupBy
### For user-deactivated.listener.spec.ts
Follow the pattern from `user-banned.listener.spec.ts`:
1. Mock `PrismaService` and `LoggerService`
2. Test scenarios:
- Successfully expires listings for deactivated user
- Updates both ACTIVE and PENDING_REVIEW listings
- Logs correct messages
- Handles case with 0 listings updated
- Handles case with multiple listings updated

## 5⃣ STYLING REFERENCE
All components use:
- **Tailwind CSS** classes directly (no CSS modules)
- **Responsive breakpoints**: `md:`, `lg:`
- **Dark mode**: Uses CSS variables in `globals.css`
- **Component pattern**: Card → CardContent
### Common spacing patterns:
```typescript
// Sections
<section className="py-16 md:py-24">
<div className="mx-auto max-w-7xl px-4">
{/* content */}
</div>
</section>
// Cards
<Card>
<CardContent className="p-4 md:p-6">
{/* content */}
</CardContent>
</Card>
// Grid
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
{/* items */}
</div>
```

### Routing Patterns
**Public Routes (under `(public)`):**
- `/` → Home/landing page
- `/listings/[id]` → Listing detail (EXISTING PATTERN)
- `/search` → Search results page
- `/compare` → Property comparison page
- `/pricing` → Pricing page
**Key Insight:** The `(public)` route group is for unauthenticated users. **Agent profiles should follow the same pattern: `/agents/[id]`** under the `(public)` group.
---
## 2. EXISTING AGENT-RELATED CODE
### Agent Profile Type (Frontend)
**File:** `apps/web/lib/profile-api.ts`
```typescript
export interface AgentProfile {
id: string;
email: string | null;
phone: string;
fullName: string;
avatarUrl: string | null;
role: string;
kycStatus: string;
isActive: boolean;
createdAt: string;
licenseNumber: string | null;
agency: string | null;
qualityScore: number | null;
serviceAreas: string[];
isVerified: boolean;
}
```
### Existing Agent API Endpoints (Backend)
**File:** `apps/api/src/modules/agents/presentation/controllers/agents.controller.ts`
```typescript
// Endpoints:
GET /agents/me/dashboard # Agent dashboard (authenticated)
POST /agents/:agentId/recalculate-score # Recalculate quality score (admin)
// Returns:
interface AgentDashboardData {
agentId: string;
qualityScore: number;
totalDeals: number;
responseTimeAvg: number | null;
isVerified: boolean;
totalLeads: number;
leadsByStatus: Record<string, number>;
conversionRate: number;
totalInquiries: number;
unreadInquiries: number;
totalListings: number;
activeListings: number;
avgReviewRating: number;
totalReviews: number;
}
```
### Prisma Schema — Agent Model
**File:** `prisma/schema.prisma`
```prisma
model Agent {
id String @id @default(cuid())
userId String @unique
user User @relation(fields: [userId], references: [id])
licenseNumber String?
agency String?
qualityScore Float @default(0)
totalDeals Int @default(0)
responseTimeAvg Int?
bio String?
serviceAreas Json // JSON array: ["quan-1", "quan-7", "thu-duc"]
isVerified Boolean @default(false)
createdAt DateTime @default(now())
updatedAt DateTime @updatedAt
listings Listing[]
leads Lead[]
@@index([qualityScore])
@@index([isVerified])
}
```
**Related models:**
- `User` — Agent's user account (fullName, avatarUrl, phone, email, role, kycStatus)
- `Listing` — Properties agent represents (has `agentId` foreign key)
- `Lead` — Leads tracked by agent
---
## 3. AGENT API ENDPOINTS NEEDED FOR PUBLIC PROFILE
Based on the existing architecture, we need to create a **public endpoint** to fetch agent profile data:
### Proposed Endpoint
```http
GET /agents/:agentId/profile
```
**Response Structure (Public Profile DTO):**
```typescript
interface AgentPublicProfile {
id: string;
fullName: string;
avatarUrl: string | null;
// Agent-specific fields
licenseNumber: string | null;
agency: string | null;
qualityScore: number;
bio: string | null;
serviceAreas: string[];
isVerified: boolean;
// Stats
totalListings: number;
activeListings: number;
avgReviewRating: number;
totalReviews: number;
// Contact (optional, may require user preferences)
phone?: string;
// Timestamps
createdAt: string;
updatedAt: string;
}
```
**Related Endpoints Needed:**
```http
GET /listings?agentId=:agentId&status=ACTIVE # Agent's active listings
GET /reviews/stats?targetType=AGENT&targetId=:agentId # Agent reviews stats
GET /reviews?targetType=AGENT&targetId=:agentId&limit=10 # Recent agent reviews
```
These endpoints already exist and are public (no authentication required).
---
## 4. SHARED UI COMPONENTS & DESIGN PATTERNS
### Tailwind/Design System
**File:** `apps/web/tailwind.config.ts`
```typescript
// CSS Variables used (dark mode support)
colors: {
primary, primary-foreground
secondary, secondary-foreground
destructive, destructive-foreground
muted, muted-foreground
accent, accent-foreground
card, card-foreground
}
// Radius variable: var(--radius)
borderRadius: {
lg: 'var(--radius)',
md: 'calc(var(--radius) - 2px)',
sm: 'calc(var(--radius) - 4px)',
}
```
### Available UI Components
**File:** `apps/web/components/ui/`
- `button.tsx` — Styled button with variants
- `card.tsx` — Card (CardContent, etc.)
- `badge.tsx` — Badge with variants
- `input.tsx`, `label.tsx` — Form controls
- `dialog.tsx` — Modal dialog
- `tabs.tsx` — Tab navigation
- `table.tsx` — Data table
### Key Component Patterns
#### Badge Component
```typescript
<Badge variant="default">Đã xác minh</Badge>
<Badge variant="secondary">Info badge</Badge>
<Badge variant="outline">Outline badge</Badge>
<Badge variant="destructive">Danger</Badge>
```
#### Card Pattern
```typescript
<Card>
<CardContent className="p-4">
{/* Content */}
</CardContent>
</Card>
```
#### Property Card (Listing Display) - REUSE THIS
**File:** `apps/web/components/search/property-card.tsx`
Shows a property with:
- Image gallery
- Price (formatted)
- Title & address
- Type, area, bedrooms badges
- Transaction type badge
**Reusable for:** Agent's listings display
---
## 5. STYLING & DESIGN PATTERNS
### Global CSS
**File:** `apps/web/app/globals.css`
Uses CSS variables for theming:
```css
--primary: hsl(var(--primary-h), var(--primary-s), var(--primary-l))
--background: hsl(...)
--card: hsl(...)
/* Dark mode support via [data-theme="dark"] */
```
### Typography
- Font: Inter (configured in tailwind.config.ts via CSS variable `--font-inter`)
- Heading levels: h1, h2, h3, h4
- Use classes: `text-lg font-bold`, `text-sm text-muted-foreground`
### Spacing
- Tailwind standard: `p-4`, `mt-8`, `gap-3`, etc.
- Card padding: `p-4`
- Section padding: `py-16`, `py-24` for hero sections
### Example Layout Pattern
```typescript
<section className="py-16 md:py-24">
<div className="mx-auto max-w-7xl px-4">
{/* Content */}
</div>
</section>
```
---
## 6. STATE MANAGEMENT & DATA FETCHING
### API Client Pattern
**File:** `apps/web/lib/api-client.ts`
```typescript
// Usage:
const apiClient = {
get: <T>(endpoint: string, headers?: HeadersInit) => request<T>(endpoint, { method: 'GET', headers }),
post: <T>(endpoint: string, body?: unknown, headers?: HeadersInit) => request<T>(endpoint, { method: 'POST', body, headers }),
patch: <T>(endpoint: string, body?: unknown, headers?: HeadersInit) => request<T>(endpoint, { method: 'PATCH', body, headers }),
delete: <T>(endpoint: string, headers?: HeadersInit) => request<T>(endpoint, { method: 'DELETE', headers }),
};
// CSRF protection included automatically
```
### Server-Side Data Fetching Pattern
**File:** `apps/web/lib/listings-server.ts`
```typescript
// Example: fetch on server at build time or request time
export async function fetchListingById(id: string) {
try {
const res = await fetch(`${API_BASE_URL}/listings/${id}`, {
next: { revalidate: 3600 } // ISR: revalidate every 1 hour
});
if (!res.ok) return null;
return res.json();
} catch {
return null;
}
}
```
### Client-Side Data Fetching Pattern
```typescript
// In React component (using 'use client')
const [data, setData] = useState(null);
React.useEffect(() => {
apiClient
.get('/endpoint')
.then((res) => setData(res))
.catch(() => setError(true))
.finally(() => setLoading(false));
}, []);
```
### No Global State (Zustand)
- **Currently no Zustand stores** for agent data in codebase
- **Pattern:** Fetch data in page component → pass to child components
- Dashboard uses local useState for profile fetch
---
## 7. SEO PATTERNS & STRUCTURED DATA
### Metadata Generation Pattern
**File:** `apps/web/app/[locale]/(public)/listings/[id]/page.tsx`
```typescript
export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
const listing = await fetchListingById(params.id);
if (!listing) {
return { title: 'Không tìm thấy' };
}
return {
title: `${property.title} - ${formatPrice(listing.priceVND)} VND`,
description: '...',
alternates: {
canonical: `${siteUrl}/${params.locale}/listings/${params.id}`,
languages: { vi: '...', en: '...' }
},
openGraph: {
type: 'article',
locale: params.locale === 'vi' ? 'vi_VN' : 'en_US',
url: canonicalUrl,
title,
images: [{ url: firstImage.url, width: 1200, height: 630 }],
},
twitter: {
card: 'summary_large_image',
title,
images: [firstImage.url],
},
};
}
```
### JSON-LD Structured Data
**File:** `apps/web/components/seo/json-ld.tsx`
```typescript
// Example: RealEstateListing schema
export function generateListingJsonLd(listing, siteUrl) {
return {
'@context': 'https://schema.org',
'@type': 'RealEstateListing',
name: property.title,
url: `${siteUrl}/listings/${listing.id}`,
offers: { '@type': 'Offer', price: priceNum, priceCurrency: 'VND' },
// ... more properties
};
}
// Usage in page:
<JsonLd data={listingJsonLd} />
<JsonLd data={breadcrumbJsonLd} />
```
### For Agent Profile (Schema.org)
**Appropriate schema:** `LocalBusiness` or `ProfessionalService`
```json
{
"@context": "https://schema.org",
"@type": "LocalBusiness",
"name": "Agent Full Name",
"description": "Bio",
"url": "https://goodgo.vn/en/agents/[id]",
"image": "avatarUrl",
"address": {
"@type": "PostalAddress",
"addressLocality": "Ho Chi Minh"
},
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": avgReviewRating,
"reviewCount": totalReviews
}
}
```
---
## 8. EXISTING LISTING CARD COMPONENTS
### Property Card Component
**File:** `apps/web/components/search/property-card.tsx`
```typescript
interface PropertyCardProps {
listing: ListingDetail;
compact?: boolean;
}
// Displays:
// - Image gallery (with count badge)
// - Price (formatted)
// - Title & address
// - Badges: Transaction type, property type, area, bedrooms, bathrooms, direction
// - Compare button
```
### Used in:
- Home page featured listings
- Search results
- Comparison page
**For Agent Profile:** Can reuse this component to display agent's listings!
---
## 9. REVIEW & RATING COMPONENTS
### Review API Endpoints
**File:** `apps/api/src/modules/reviews/presentation/controllers/reviews.controller.ts`
```typescript
// Endpoints:
GET /reviews # List reviews by target (pagination)
GET /reviews/stats # Get aggregate rating stats
GET /reviews/me # Get authenticated user's reviews
POST /reviews # Create review (authenticated)
DELETE /reviews/:id # Delete own review
// Query params:
GET /reviews?targetType=AGENT&targetId=:id&page=1&limit=20
GET /reviews/stats?targetType=AGENT&targetId=:id
```
### Review DTO
```typescript
interface ReviewItemData {
id: string;
userId: string;
targetType: string;
targetId: string;
rating: number; // 1-5
comment: string | null;
createdAt: string;
// User info:
user: {
id: string;
fullName: string;
avatarUrl: string | null;
};
}
interface ReviewStatsData {
targetType: string;
targetId: string;
totalReviews: number;
averageRating: number;
ratingDistribution: {
"1": number;
"2": number;
"3": number;
"4": number;
"5": number;
};
}
```
### No Review Display Component Yet
- **Dashboard profile** shows `agentProfile.totalReviews` and `avgReviewRating`
- **Opportunity:** Create a reusable `ReviewCard` and `RatingStars` component for agent profile
---
## 10. TYPE DEFINITIONS & INTERFACES
### Core Types Used Frontend
```typescript
// From listings-api.ts
export type TransactionType = 'SALE' | 'RENT';
export type PropertyType = 'APARTMENT' | 'HOUSE' | 'VILLA' | 'LAND' | 'OFFICE' | 'SHOPHOUSE';
export type ListingStatus = 'DRAFT' | 'PENDING_REVIEW' | 'ACTIVE' | 'RESERVED' | 'SOLD' | 'RENTED' | 'EXPIRED' | 'REJECTED';
export type Direction = 'NORTH' | 'SOUTH' | 'EAST' | 'WEST' | 'NORTHEAST' | 'NORTHWEST' | 'SOUTHEAST' | 'SOUTHWEST';

kycStatus: string;
isActive: boolean;
createdAt: string;
licenseNumber: string | null;
agency: string | null;
qualityScore: number | null;
serviceAreas: string[];

title: string;
areaM2: number;
address: string;
ward: string;

city: string;
media: PropertyMedia[];
// ... 15+ other properties
};
}
```
### Validation Schemas (Zod)
**File:** `apps/web/lib/validations/listings.ts`
```typescript
export const TRANSACTION_TYPES = [
{ value: 'SALE', label: 'Bán' },
{ value: 'RENT', label: 'Cho thuê' },
] as const;
export const PROPERTY_TYPES = [
{ value: 'APARTMENT', label: 'Căn hộ' },
{ value: 'HOUSE', label: 'Nhà riêng' },
// ... more
] as const;
export const LISTING_STATUSES = {

## 11. IMPLEMENTATION CHECKLIST FOR AGENT PROFILE PAGE
### Backend (NestJS API)
**New DTO & Interfaces:**
```
✓ CreateGetAgentPublicProfileQuery
✓ GetAgentPublicProfileHandler
✓ AgentPublicProfileDto (response)
✓ Update agent.repository.ts with method: getPublicProfile(agentId: string)
✓ Update prisma-agent.repository.ts to fetch via Prisma
```
**New Endpoint:**
```
✓ GET /agents/:agentId/profile (public, no auth)
✓ Returns: AgentPublicProfileDto
✓ Validates agentId exists
✓ Returns 404 if not found
```
**Leverage Existing:**
- Review queries: Already public
- Listings queries: Already public
- User profile: Linking to agent.userId
### Frontend (Next.js)
**New Files:**
```
✓ apps/web/app/[locale]/(public)/agents/ (directory)
✓ apps/web/app/[locale]/(public)/agents/[id]/ (directory)
✓ apps/web/app/[locale]/(public)/agents/[id]/page.tsx (server component)
✓ apps/web/app/[locale]/(public)/agents/[id]/layout.tsx (optional)
✓ apps/web/lib/agents-api.ts (API client)
✓ apps/web/lib/agents-server.ts (server-side fetch for ISR)
✓ apps/web/components/agents/ (new directory)
✓ apps/web/components/agents/agent-detail-client.tsx (client component)
✓ apps/web/components/agents/agent-listings-section.tsx
✓ apps/web/components/agents/agent-reviews-section.tsx
```
**Page Structure (follows listing pattern):**
```typescript
// [id]/page.tsx (Server Component)
export async function generateMetadata({ params }): Promise<Metadata> {
// Fetch agent
// Return title, description, OG image, canonical URL
}
export default async function AgentProfilePage({ params }) {
// Fetch agent profile (server-side, ISR)
// Render JsonLd breadcrumb
// Render JsonLd LocalBusiness or ProfessionalService
// Pass to client component
return <>
<JsonLd data={agentJsonLd} />
<AgentDetailClient agent={agent} />
</>
}
```
**Client Component:**
- Display agent info (name, avatar, bio, license, agency)
- Show quality score & badges
- Render reviews section
- Render listings section
- Contact/inquiry button (optional)
**API Client:**
```typescript
export const agentsApi = {
getById: (id: string) => apiClient.get<AgentPublicProfile>(`/agents/${id}/profile`),
};
```

## 12. KEY FILES TO REFERENCE/ADAPT
### Backend
| File | Purpose |
|------|---------|
| `apps/api/src/modules/agents/presentation/controllers/agents.controller.ts` | Add new public endpoint |
| `apps/api/src/modules/agents/domain/repositories/agent.repository.ts` | Add interface for public profile method |

| `apps/api/src/modules/agents/application/queries/` | Create new query handler for public profile |
| `prisma/schema.prisma` | Reference for Agent model |
### Frontend — Reference Examples
| File | Purpose | Reuse Pattern |
|------|---------|---|
| `apps/web/app/[locale]/(public)/listings/[id]/page.tsx` | Listing detail page | Use as template for agent page |
| `apps/web/components/search/property-card.tsx` | Property card | Reuse for agent's listings |
| `apps/web/lib/listings-api.ts` | Listings API client | Create similar agents-api.ts |
| `apps/web/lib/listings-server.ts` | Server-side fetch | Create similar agents-server.ts |
| `apps/web/components/seo/json-ld.tsx` | Structured data | Adapt for LocalBusiness schema |

## 13. SUMMARY OF KEY FINDINGS
### What Exists (Reusable)
✅ Agent model in Prisma with all needed fields
✅ API endpoints for listings, reviews (public)
✅ UI components: Card, Badge, Button, etc.
✅ Tailwind design system with dark mode
✅ SEO pattern with metadata generation & JSON-LD
✅ Image gallery component for listings
✅ PropertyCard component for listings display
✅ API client with CSRF protection
✅ Server-side data fetching with ISR pattern
### What Needs Building (Agent Profile)
🔨 `/agents/[id]` page (server component with metadata)
🔨 `AgentDetailClient` component (client-side rendering)
🔨 Public endpoint: `GET /agents/:agentId/profile`
🔨 Agent listings section (reuse PropertyCard)
🔨 Agent reviews section (fetch & display reviews)
🔨 Rating stars/aggregate display component
🔨 agents-api.ts (fetch agent profile)
🔨 agents-server.ts (server-side fetch for ISR)
🔨 JSON-LD LocalBusiness schema for agent
### Architecture Decisions
- **Routing:** Place at `apps/web/app/[locale]/(public)/agents/[id]/page.tsx`
- **Pattern:** Follow listing detail page pattern exactly
- **Metadata:** Use generateMetadata() server function
- **Components:** Split into Server Component (page) + Client Component (interactive)
- **SEO:** Include breadcrumb + LocalBusiness JSON-LD
- **Styling:** Use existing Tailwind tokens + components
- **Data Fetching:** Server-side fetch with ISR revalidation (3600s)
---
## 14. NEXT STEPS
1. **Design API DTO** for public agent profile
2. **Create backend query handler** for fetching public agent profile
3. **Create frontend API client** (agents-api.ts)

├── get-agent-profile.query.ts
└── get-agent-profile.handler.ts
apps/api/src/modules/agents/presentation/dto/
└── agent-public-profile.dto.ts
```
---
## 🎨 Frontend Architecture
### Directory Structure to Create
```
apps/web/
├── app/[locale]/(public)/agents/
│ └── [id]/
│ ├── page.tsx ← Server component (metadata, ISR)
│ └── layout.tsx ← Optional shared layout
├── components/agents/
│ ├── agent-detail-client.tsx ← Main interactive component
│ ├── agent-header.tsx ← Profile info section
│ ├── agent-listings-section.tsx ← Grid of listings
│ └── agent-reviews-section.tsx ← Reviews with stars
└── lib/
├── agents-api.ts ← API client
└── agents-server.ts ← Server-side ISR fetch
```
---
## 🔄 Data Flow
```
1. Browser requests: /agents/[id]
2. Next.js generates metadata (SEO)
- Title: "Agent Name — Real Estate Agent at GoodGo"
- Description: Bio + stats
- Image: Avatar
- Canonical URL
3. Server-side fetch agent profile data
- GET /api/v1/agents/:id/profile (ISR: revalidate 3600s)
4. Render Server Component with metadata + JSON-LD
5. Pass data to Client Component for interactivity
- Fetch reviews in parallel
- Fetch listings in parallel
6. Client renders:
- Agent header (avatar, name, stats, badges)
- Reviews section (star ratings, comment cards)
- Listings section (reuse PropertyCard component)
```
---
## 🎭 Component Composition
### Server Component (page.tsx)
```typescript
export async function generateMetadata({ params }): Promise<Metadata> {
// 1. Fetch agent using agents-server.ts
// 2. Build SEO metadata
// 3. Return title, description, OG, canonical
}
export default async function AgentProfilePage({ params }) {
// 1. Fetch agent profile (with ISR)
// 2. Generate JSON-LD (LocalBusiness schema)
// 3. Render <JsonLd> for structured data
// 4. Pass agent to client component
return <>
<JsonLd data={agentJsonLd} />
<AgentDetailClient agent={agent} />
</>
}
```
### Client Component (agent-detail-client.tsx)
```typescript
'use client';
export function AgentDetailClient({ agent }: Props) {
const [listings, setListings] = useState([]);
const [reviews, setReviews] = useState([]);
const [reviewStats, setReviewStats] = useState(null);
useEffect(() => {
// Fetch agent's active listings
// Fetch reviews & stats
}, [agent.id]);
return <>
<AgentHeader agent={agent} />
<AgentReviewsSection reviews={reviews} stats={reviewStats} />
<AgentListingsSection listings={listings} />
</>
}
```

## 🔍 Key Design Decisions
1. **Routing:** Agent profiles under `(public)` group, same as listings
2. **Pattern:** Follow listing detail page pattern exactly (copy/paste approach)
3. **Data Fetching:** Server-side with ISR (1 hour revalidation)
4. **State:** Client-side useState for reviews/listings (no Zustand)
5. **Components:** Split into Page (server) + Client (interactive)
6. **SEO:** LocalBusiness JSON-LD schema for agent
7. **Styling:** Reuse existing UI components & Tailwind tokens
8. **Reviews:** Leverage existing /reviews endpoints (already public)
---
## 🚀 Getting Started
### Step 1: Read the Docs
- [ ] Read `AGENT_PROFILE_QUICK_REFERENCE.md` (10 min)
- [ ] Skim `AGENT_PROFILE_EXPLORATION.md` (20 min)
### Step 2: Backend Implementation
- [ ] Copy code from `AGENT_PROFILE_CODE_EXAMPLES.md` (Phase 1)
- [ ] Adapt to your codebase
- [ ] Test with Postman
### Step 3: Frontend Implementation
- [ ] Create directory structure
- [ ] Copy components from code examples (Phase 2-3)
- [ ] Wire up data fetching
- [ ] Add SEO metadata
### Step 4: Testing
- [ ] Manual testing
- [ ] Lighthouse audit
- [ ] E2E test (agent profile page)
---
## 💡 Implementation Tips
1. **Copy the listing detail page structure** — Agent page should be ~90% similar
2. **Reuse PropertyCard component** — For displaying agent's listings
3. **Use existing review endpoints** — Already public and don't need auth
4. **Follow i18n patterns** — Agent name/bio may need translation
5. **Test 404 handling** — When agent doesn't exist
6. **Cache agent profile** — 1 hour ISR matches listing pattern
---
## 📖 Reference Files in Codebase
### Pattern to Copy
-`app/[locale]/(public)/listings/[id]/page.tsx` — Page structure
-`components/search/property-card.tsx` — Card pattern
-`lib/listings-api.ts` — API client pattern
-`lib/listings-server.ts` — Server fetch pattern
-`components/seo/json-ld.tsx` — JSON-LD pattern
### Endpoints to Use
-`GET /listings?agentId=:id` — Existing
-`GET /reviews?targetType=AGENT` — Existing
-`GET /reviews/stats?targetType=AGENT` — Existing
### Components to Reuse
-`Card`, `CardContent` — Layout
-`Badge` — Status/stats display
-`Button` — CTAs
-`Image` — Avatar & property photos
-`PropertyCard` — Listings display
---
## ❓ FAQ
**Q: How long does this take to implement?**
A: 6-8 hours total (1-2h backend, 1h setup, 2-3h UI, 1h SEO, 1h testing)
**Q: Do I need to create new backend endpoints?**
A: Yes, 1 new endpoint: `GET /agents/:agentId/profile`. Reviews/listings endpoints already exist.
**Q: Can I reuse components from the listing page?**
A: Yes! PropertyCard, metadata generation, JSON-LD structure can all be adapted.
**Q: How do I handle pagination for listings/reviews?**
A: Use the same pagination as listing detail page (`limit`, `offset`, `page`)
**Q: What about internationalization?**
A: Agent fullName/bio come from database; use existing i18n patterns in codebase
**Q: How is SEO handled?**
A: Server-side metadata generation + LocalBusiness JSON-LD schema

# Detailed Handler Comparison & Code Patterns
## File Structure Comparison
### Tested Handler Pattern: approve-listing
```
approve-listing/
├── approve-listing.command.ts (simple class)
├── approve-listing.handler.ts (the handler to test)
└── (no query.ts - it's a Command, not a Query)
Test file:
└── approve-listing.handler.spec.ts
```
### Untested Handler: reject-listing
```
reject-listing/
├── reject-listing.command.ts (simple class)
├── reject-listing.handler.ts (NEEDS TEST)
└── (no query.ts - it's a Command, not a Query)
Test file:
└── ❌ MISSING: reject-listing.handler.spec.ts
```
---
## Side-by-Side Handler Comparison
### APPROVE Listing Handler:
```typescript
@CommandHandler(ApproveListingCommand)
export class ApproveListingHandler implements ICommandHandler<ApproveListingCommand> {
constructor(
@Inject(LISTING_REPOSITORY) private readonly listingRepo: IListingRepository,
private readonly eventBus: EventBus,
) {}
async execute(command: ApproveListingCommand): Promise<ApproveLis tingResult> {
// 1. Find listing
const listing = await this.listingRepo.findById(command.listingId);
if (!listing) {
throw new NotFoundException('Listing không tồn tại');
}
// 2. Check status
if (listing.status !== 'PENDING_REVIEW') {
throw new ValidationException(
`Listing đang ở trạng thái ${listing.status}, chỉ có thể phê duyệt listing đang chờ duyệt`,
{ currentStatus: listing.status },
);
}
// 3. Apply domain logic
listing.approve(command.notes);
// 4. Persist
await this.listingRepo.update(listing);
// 5. Publish event
this.eventBus.publish(
new ListingApprovedEvent(listing.id, command.adminId, command.notes),
);
// 6. Return result
return {
listingId: listing.id,
status: 'ACTIVE',
message: 'Listing đã được phê duyệt',
};
}
}
```
### REJECT Listing Handler (virtually identical pattern):
```typescript
@CommandHandler(RejectListingCommand)
export class RejectListingHandler implements ICommandHandler<RejectListingCommand> {
constructor(
@Inject(LISTING_REPOSITORY) private readonly listingRepo: IListingRepository,
private readonly eventBus: EventBus,
) {}
async execute(command: RejectListingCommand): Promise<RejectListingResult> {
// 1. Find listing
const listing = await this.listingRepo.findById(command.listingId);
if (!listing) {
throw new NotFoundException('Listing không tồn tại');
}
// 2. Check status (same as approve!)
if (listing.status !== 'PENDING_REVIEW') {
throw new ValidationException(
`Listing đang ở trạng thái ${listing.status}, chỉ có thể từ chối listing đang chờ duyệt`,
{ currentStatus: listing.status },
);
}
// 3. Apply domain logic (different method: reject instead of approve)
listing.reject(command.reason);
// 4. Persist
await this.listingRepo.update(listing);
// 5. Publish event (different event type)
this.eventBus.publish(
new ListingRejectedEvent(listing.id, command.adminId, command.reason),
);
// 6. Return result (different status)
return {
listingId: listing.id,
status: 'REJECTED',
message: 'Listing đã bị từ chối',
};
}
}
```
### Differences:
| Aspect | Approve | Reject |
|--------|---------|--------|
| Domain Method | `listing.approve()` | `listing.reject()` |
| Event | `ListingApprovedEvent` | `ListingRejectedEvent` |
| Result Status | `'ACTIVE'` | `'REJECTED'` |
| Result Message | `'Listing đã được phê duyệt'` | `'Listing đã bị từ chối'` |

## Test Code Walkthrough
### ApproveListingHandler Test:
```typescript
describe('ApproveListingHandler', () => {
let handler: ApproveListingHandler;
let mockListingRepo: { [K in keyof IListingRepository]: ReturnType<typeof vi.fn> };
let mockEventBus: { publish: ReturnType<typeof vi.fn> };
// SETUP: Create fresh mocks for each test
beforeEach(() => {
mockListingRepo = {
findById: vi.fn(),
findByIdWithProperty: vi.fn(),
save: vi.fn(),
update: vi.fn(),
search: vi.fn(),
findByStatus: vi.fn(),
findBySellerId: vi.fn(),
};
mockEventBus = { publish: vi.fn() };
// Instantiate handler with mocks
handler = new ApproveListingHandler(
mockListingRepo as any,
mockEventBus as any,
);
});
// TEST 1: Happy Path - Successfully approve
it('approves a pending listing successfully', async () => {
// Arrange: Create a listing entity in PENDING_REVIEW state
const listing = createPendingListing();
mockListingRepo.findById.mockResolvedValue(listing);
mockListingRepo.update.mockResolvedValue(undefined);
// Act: Execute the command
const command = new ApproveListingCommand('listing-1', 'admin-1', 'Looks good');
const result = await handler.execute(command);
// Assert: Verify result
expect(result.status).toBe('ACTIVE');
expect(result.listingId).toBe('listing-1');
// Assert: Verify side effects
expect(mockListingRepo.update).toHaveBeenCalledTimes(1);
expect(mockEventBus.publish).toHaveBeenCalled();
});
// TEST 2: Error - Listing not found
it('throws NotFoundException when listing does not exist', async () => {
// Arrange: Mock returns null (not found)
mockListingRepo.findById.mockResolvedValue(null);
// Act & Assert: Expect exception
const command = new ApproveListingCommand('nonexistent', 'admin-1');
await expect(handler.execute(command)).rejects.toThrow('Listing không tồn tại');
});
// TEST 3: Error - Wrong status
it('throws ValidationException when listing is not pending review', async () => {
// Arrange: Create listing NOT in PENDING_REVIEW status
const price = Price.create(500_000_000n).unwrap();
const listing = ListingEntity.createNew(
'listing-1', 'prop-1', 'seller-1', 'SALE', price, 80,
);
listing.clearDomainEvents();
mockListingRepo.findById.mockResolvedValue(listing);
// Act & Assert: Expect exception
const command = new ApproveListingCommand('listing-1', 'admin-1');
await expect(handler.execute(command)).rejects.toThrow(/trạng thái/);
});
});
```
### How to adapt for RejectListingHandler:
1. **Import changes:**
```typescript
import { RejectListingCommand } from '../commands/reject-listing/reject-listing.command';
import { RejectListingHandler } from '../commands/reject-listing/reject-listing.handler';
// Keep everything else the same
```
2. **Test 1 (Happy path) changes:**
```typescript
it('rejects a pending listing successfully', async () => {
const listing = createPendingListing();
mockListingRepo.findById.mockResolvedValue(listing);
mockListingRepo.update.mockResolvedValue(undefined);
const command = new RejectListingCommand('listing-1', 'admin-1', 'Too many issues');
const result = await handler.execute(command);
expect(result.status).toBe('REJECTED'); // Changed from 'ACTIVE'
expect(result.message).toContain('từ chối'); // Changed assertion
expect(mockListingRepo.update).toHaveBeenCalledTimes(1);
expect(mockEventBus.publish).toHaveBeenCalled();
});
```
3. **Tests 2 & 3 remain almost identical** (only import names change)
---
## Query Handler Comparison
### Tested Query Handler: get-dashboard-stats
```typescript
@QueryHandler(GetDashboardStatsQuery)
export class GetDashboardStatsHandler implements IQueryHandler<GetDashboardStatsQuery> {
constructor(
@Inject(ADMIN_QUERY_REPOSITORY) private readonly adminQueryRepo: IAdminQueryRepository,
) {}
async execute(query: GetDashboardStatsQuery): Promise<DashboardStats> {
return this.adminQueryRepo.getDashboardStats();
}
}
```
### Untested Query Handler: get-revenue-stats
```typescript
@QueryHandler(GetRevenueStatsQuery)
export class GetRevenueStatsHandler implements IQueryHandler<GetRevenueStatsQuery> {
constructor(
@Inject(ADMIN_QUERY_REPOSITORY) private readonly adminQueryRepo: IAdminQueryRepository,
) {}
async execute(query: GetRevenueStatsQuery): Promise<RevenueStatsItem[]> {
// KEY DIFFERENCE: Passes query params to repo method
return this.adminQueryRepo.getRevenueStats(query.startDate, query.endDate, query.groupBy);
}
}
```
### Query Handler Test Pattern:
```typescript
describe('GetRevenueStatsHandler', () => {
let handler: GetRevenueStatsHandler;
let mockAdminQueryRepo: { [K in keyof IAdminQueryRepository]: ReturnType<typeof vi.fn> };
beforeEach(() => {
mockAdminQueryRepo = {
getModerationQueue: vi.fn(),
getDashboardStats: vi.fn(),
getRevenueStats: vi.fn(), // This one will be tested
getUsers: vi.fn(),
};
handler = new GetRevenueStatsHandler(mockAdminQueryRepo as any);
});
it('returns revenue stats for date range', async () => {
// Arrange: Mock data
const mockStats: RevenueStatsItem[] = [
{
period: '2024-04',
totalRevenue: 50000000n,
subscriptionRevenue: 30000000n,
listingFeeRevenue: 15000000n,
featuredListingRevenue: 5000000n,
transactionCount: 125,
},
];
mockAdminQueryRepo.getRevenueStats.mockResolvedValue(mockStats);
// Act
const startDate = new Date('2024-04-01');
const endDate = new Date('2024-04-30');
const query = new GetRevenueStatsQuery(startDate, endDate, 'month');
const result = await handler.execute(query);
// Assert: Verify result
expect(result).toEqual(mockStats);
// Assert: Verify params passed correctly
expect(mockAdminQueryRepo.getRevenueStats).toHaveBeenCalledWith(
startDate,
endDate,
'month'
);
expect(mockAdminQueryRepo.getRevenueStats).toHaveBeenCalledTimes(1);
});
it('supports day grouping', async () => {
mockAdminQueryRepo.getRevenueStats.mockResolvedValue([]);
const query = new GetRevenueStatsQuery(
new Date('2024-04-01'),
new Date('2024-04-30'),
'day' // Changed parameter
);
await handler.execute(query);
expect(mockAdminQueryRepo.getRevenueStats).toHaveBeenCalledWith(
expect.any(Date),
expect.any(Date),
'day' // Verify 'day' was passed
);
});
it('returns empty array when no data', async () => {
mockAdminQueryRepo.getRevenueStats.mockResolvedValue([]);
const query = new GetRevenueStatsQuery(
new Date('2024-01-01'),
new Date('2024-01-01')
);
const result = await handler.execute(query);
expect(result).toEqual([]);
expect(result.length).toBe(0);
});
});
```
---
## Listener Comparison
### UserBannedListener (Tested):
```typescript
@Injectable()
export class UserBannedListener {
constructor(
private readonly commandBus: CommandBus,
private readonly prisma: PrismaService,
private readonly logger: LoggerService,
) {}
@OnEvent('user.banned', { async: true })
async handle(event: UserBannedEvent): Promise<void> {
this.logger.log(`Handling user.banned for user ${event.aggregateId}`, 'UserBannedListener');
// Deactivate listings
const deactivated = await this.prisma.listing.updateMany({
where: {
sellerId: event.aggregateId,
status: { in: ['ACTIVE', 'PENDING_REVIEW', 'DRAFT'] },
},
data: { status: 'EXPIRED' },
});
this.logger.log(
`Deactivated ${deactivated.count} listings for banned user ${event.aggregateId}`,
'UserBannedListener',
);
// Send email notification
const user = await this.prisma.user.findUnique({
where: { id: event.aggregateId },
select: { id: true, email: true },
});
if (user?.email) {
await this.commandBus.execute(
new SendNotificationCommand(
user.id,
'EMAIL',
'user.banned',
{ reason: event.reason },
user.email,
),
);
}
}
}
```
### UserDeactivatedListener (Untested):
```typescript
@Injectable()
export class UserDeactivatedListener {
constructor(
private readonly prisma: PrismaService,
private readonly logger: LoggerService,
) {}
@OnEvent('user.deactivated', { async: true })
async handle(event: UserDeactivatedEvent): Promise<void> {
this.logger.log(`Handling user.deactivated for user ${event.aggregateId}`, 'UserDeactivatedListener');
// Similar to UserBannedListener but:
// 1. NO CommandBus (simpler)
// 2. NO email notification
// 3. Different status list: ['ACTIVE', 'PENDING_REVIEW'] (no DRAFT)
const deactivated = await this.prisma.listing.updateMany({
where: {
sellerId: event.aggregateId,
status: { in: ['ACTIVE', 'PENDING_REVIEW'] },
},
data: { status: 'EXPIRED' },
});
this.logger.log(
`Expired ${deactivated.count} listings for deactivated user ${event.aggregateId}`,
'UserDeactivatedListener',
);
}
}
```
### Key Differences:
| Aspect | UserBanned | UserDeactivated |
|--------|-----------|-----------------|
| Event name | `'user.banned'` | `'user.deactivated'` |
| Has CommandBus | ✅ Yes (for email) | ❌ No |
| Status list | `['ACTIVE', 'PENDING_REVIEW', 'DRAFT']` | `['ACTIVE', 'PENDING_REVIEW']` |
| Sends notification | ✅ Yes (email) | ❌ No |
| Complexity | Higher | Lower |
### Listener Test Pattern (simplified for UserDeactivated):
```typescript
describe('UserDeactivatedListener', () => {
let listener: UserDeactivatedListener;
let mockPrisma: {
listing: { updateMany: ReturnType<typeof vi.fn> };
};
let mockLogger: { log: ReturnType<typeof vi.fn> };
beforeEach(() => {
mockPrisma = {
listing: { updateMany: vi.fn().mockResolvedValue({ count: 5 }) },
};
mockLogger = { log: vi.fn() };
listener = new UserDeactivatedListener(mockPrisma as any, mockLogger as any);
});
it('expires all active and pending review listings for deactivated user', async () => {
await listener.handle({
aggregateId: 'user-123',
eventName: 'user.deactivated',
occurredAt: new Date(),
});
expect(mockPrisma.listing.updateMany).toHaveBeenCalledWith({
where: {
sellerId: 'user-123',
status: { in: ['ACTIVE', 'PENDING_REVIEW'] },
},
data: { status: 'EXPIRED' },
});
});
it('logs handling start and result', async () => {
await listener.handle({
aggregateId: 'user-123',
eventName: 'user.deactivated',
occurredAt: new Date(),
});
expect(mockLogger.log).toHaveBeenCalledTimes(2);
expect(mockLogger.log).toHaveBeenNthCalledWith(
1,
expect.stringContaining('user-123'),
'UserDeactivatedListener'
);
expect(mockLogger.log).toHaveBeenNthCalledWith(
2,
expect.stringContaining('Expired 5 listings'),
'UserDeactivatedListener'
);
});
it('handles zero listings case', async () => {
mockPrisma.listing.updateMany.mockResolvedValue({ count: 0 });
await listener.handle({
aggregateId: 'user-xyz',
eventName: 'user.deactivated',
occurredAt: new Date(),
});
expect(mockLogger.log).toHaveBeenNthCalledWith(
2,
expect.stringContaining('Expired 0 listings'),
'UserDeactivatedListener'
);
});
});

# Image Usage Audit Report - GoodGo Web App (apps/web/)
**Generated:** 2026-04-11
**Scope:** Complete audit of image usage across .tsx, .ts, and .jsx files
---
## 🎯 Executive Summary
The Next.js web app shows **excellent image optimization practices**:
-**No HTML `<img>` tags** used in production components
-**Next.js Image component** properly implemented across all visual components
-**CSP and remotePatterns** configured correctly
- ⚠️ **Only 4 HTML `<img>` tags** found (all in test mocks - acceptable)
-**3 dedicated image components** handling upload, gallery, and lightbox
---
## 📊 Statistics
| Metric | Count |
|--------|-------|
| Files using `next/image` | 8 |
| Files with HTML `<img>` tags (production) | 0 |
| Image-related components | 3 |
| Test mocks with `<img>` | 3 |
| Image utility files | 0 |
| Total image-related code lines | ~651 |
---
## 1. HTML `<img>` Tags Found
### ✅ Production Usage: **NONE**
No HTML `<img>` tags found in production code.
### ⚠️ Test Mocks: 4 instances
These are **acceptable** - they're test mocks of the Next.js Image component:
| File | Line | Context | Type |
|------|------|---------|------|
| `app/[locale]/(public)/__tests__/landing.spec.tsx` | 37 | Mock for `next/image` in test | Jest Mock |
| `app/[locale]/(public)/search/__tests__/search.spec.tsx` | 46 | Mock for `next/image` in test | Jest Mock |
| `app/[locale]/(dashboard)/dashboard/__tests__/dashboard.spec.tsx` | 14 | Mock for `next/image` in test | Jest Mock |
| `components/listings/image-upload.tsx` | 144 | Preview image for file upload | Production (fallback from blob URL) |
**Note on image-upload.tsx line 144:**
This is a **preview image** using `blob: URL` for file uploads before submission:
```tsx
<img
src={img.preview} // blob: URL from URL.createObjectURL(file)
alt={`Ảnh ${index + 1}`}
className="h-full w-full object-cover"
/>
```
This is appropriate since the image is a temporary blob URL that doesn't exist on remote servers.
---
## 2. `next/image` Imports Found
### ✅ Files Using Next.js Image Component: 8
| File | Location | Usage |
|------|----------|-------|
| `components/listings/image-gallery.tsx` | Line 3 | Gallery main image display & thumbnails |
| `components/listings/image-lightbox.tsx` | Line 3 | Fullscreen image viewer |
| `components/search/property-card.tsx` | Line 1 | Property card thumbnail images |
| `components/agents/agent-profile-client.tsx` | Line 14 | Agent avatar & agent listing images |
| `components/comparison/comparison-table.tsx` | Line 4 | Comparison table property images |
| `app/[locale]/(admin)/admin/kyc/page.tsx` | - | Admin KYC page (likely for document images) |
| `app/[locale]/(dashboard)/listings/page.tsx` | - | Dashboard listings view |
| `app/[locale]/(dashboard)/dashboard/page.tsx` | - | Dashboard overview |
### Image Component Usage Summary:
- **Primary use:** Property listing images
- **Secondary use:** Agent avatars
- **Responsive sizing:** Using `sizes` prop correctly
- **Priority loading:** `priority` prop used for above-fold images
- **Fallbacks:** Placeholder divs when images unavailable
---
## 3. Property/Listing Related Components
### 🏗️ Image-Specific Components (3)
#### 1. **ImageGallery** (`components/listings/image-gallery.tsx`)
- **Lines:** 127 total
- **Purpose:** Main gallery viewer with thumbnails
- **Features:**
- Uses `Image` from `next/image` (lines 46, 106)
- Main image with `fill` + `sizes` prop

### 📦 Components That Render Property Images
| Component | File | Image Usage |
|-----------|------|-------------|
| **PropertyCard** | `components/search/property-card.tsx` | First listing media as card thumbnail |
| **ListingDetailClient** | `components/listings/listing-detail-client.tsx` | Integrates `ImageGallery` component (line 92) |
| **AgentProfileClient** | `components/agents/agent-profile-client.tsx` | Agent avatar + agent's active listings images |
| **ComparisonTable** | `components/comparison/comparison-table.tsx` | First media for each listing in comparison |
| **ListingCard** (in AgentProfileClient) | `components/agents/agent-profile-client.tsx` | Listing images in agent's portfolio |
---
## 4. Next.js Image Configuration
### File: `apps/web/next.config.js`
```javascript
images: {
remotePatterns: [
{
protocol: 'https',
hostname: '**',
},
],
},
```
### ✅ Configuration Analysis:
**Strengths:**
- ✅ Permissive remotePatterns allows all HTTPS domains
- ✅ Sensible for a platform listing properties from multiple sources
- ✅ Protocol restricted to HTTPS only (security best practice)
**Considerations:**
- The `hostname: '**'` wildcard allows images from any domain
- This is acceptable if all image URLs are user-validated
- Recommend validating image URLs in the API layer before returning to frontend
### CSP Headers (lines 34-47):
```javascript
'img-src 'self' data: blob: https://*.mapbox.com https://*.tiles.mapbox.com https:',
```
**Analysis:**
- ✅ Allows `blob:` URLs (for image-upload preview)
- ✅ Allows `data:` URLs (inline base64 images)
- ✅ Allows self-hosted images
- ✅ Allows Mapbox tile images
- ✅ Allows all HTTPS sources
---
## 5. Image-Related Utilities & Helpers
### Files Checked:
-`lib/` directory - No dedicated image utilities found
-`components/ui/` - No image components beyond gallery/upload
-`hooks/` - No image-specific hooks (image management handled inline)
### Inline Utilities Found:
#### In `image-upload.tsx`:
- `URL.createObjectURL()` for blob preview generation (line 36)
- `URL.revokeObjectURL()` for cleanup (lines 50, 80)
#### In `image-lightbox.tsx`:
- Custom `useSwipe()` hook (lines 19-52) - touch gesture support
- Custom `useFocusTrap()` hook (lines 56-99) - accessibility
- Image preloading with `new window.Image()` (line 185)
#### In `image-gallery.tsx`:
- No custom utilities, uses Next.js Image optimizations
---
## 6. Image Data Types
### PropertyMedia Type (from listings-api):
```typescript
interface PropertyMedia {
id: string;
url: string; // Image URL
type: 'image' | 'video'; // Media type
order: number; // Display order
caption?: string; // Optional caption
}
```
### ImageFile Type (from image-upload):
```typescript
interface ImageFile {
file: File; // Browser File object
preview: string; // Object URL (blob:)
}
```
---
## 7. Image Handling in Key Pages
### Property Listing Detail: `app/[locale]/(public)/listings/[id]/page.tsx`
- Imports `ListingDetailClient` component
- Passes property media to `ImageGallery`
- Displays multiple images with gallery controls
### Search Results: `app/[locale]/(public)/search/page.tsx`
- Renders multiple `PropertyCard` components
- Each shows first image as thumbnail
- Uses responsive Image component
### Agent Profile: `app/[locale]/(public)/agents/[id]/page.tsx`
- Shows agent avatar
- Displays agent's active listings with images
- Uses `AgentProfileClient` component
### Listings Dashboard: `app/[locale]/(dashboard)/listings/new/page.tsx`
- Includes `ImageUpload` component for adding property images
- Handles image file selection and preview
---
## 8. Accessibility & Performance
### ✅ Accessibility Features:
- `alt` text on all images
- Vietnamese localization of alt text (culturally appropriate)
- ARIA labels for image galleries
- Keyboard navigation in lightbox (Arrow keys, Escape)
- Focus trap in modal
- Tab trapping in lightbox for accessibility
### ✅ Performance Optimizations:
- `priority` prop for above-fold images
- `sizes` prop for responsive images
- Proper `fill` + `sizes` for gallery
- Image preloading in lightbox
- Blob URL cleanup on unmount
- Object URL revocation to prevent memory leaks
### ⚠️ Potential Improvements:
- Consider implementing image lazy-loading beyond Next.js defaults
- Could add skeleton loading states during image load
- Consider blur placeholder images for better UX
---
## 9. Security Observations
### ✅ Secure Practices:
- Remote patterns restricted to HTTPS only
- CSP headers properly configured
- `blob:` URLs only used for temporary client-side previews
- No inline image data in components
### ⚠️ Points to Monitor:
- Validate image URLs at API layer before returning
- Ensure user-uploaded images are scanned for malicious content
- Consider CDN integration with image optimization if scaling

## 🆘 Troubleshooting
**API not healthy?**
```bash
docker compose exec api curl http://localhost:3001/health/ready
docker compose logs api --tail=50
```
**Database connection pooling full?**
```bash
docker compose exec pgbouncer psql -h 127.0.0.1 -p 6432 -U pgbouncer_stats -c "SHOW stats"
```
**Redis down?**
```bash
docker compose exec redis redis-cli ping
# App continues working (DB fallback), but slower
```
**Typesense not indexing?**
```bash
curl http://localhost:8108/collections/listings -H "X-TYPESENSE-API-KEY: ${KEY}"
# Reindex: docker compose exec api npx ts-node scripts/reindex-listings.ts
```
**Payment callback failing?**
```bash
docker compose logs api | grep -i callback
# Check VNPAY_HASH_SECRET / MOMO_SECRET_KEY / ZALOPAY_KEY1
```
**Backup stuck?**
```bash
docker compose exec pg-backup bash -c "tail -f /var/log/pg-backup.log"
docker compose exec postgres psql -U goodgo -d goodgo -c "SELECT * FROM pg_stat_activity WHERE wait_event_type IS NOT NULL;"
```

### **Data Flow**
**Creating Inquiry:**
```
POST /inquiries (CreateInquiryDto)
→ InquiriesController.createInquiry()
→ CommandBus.execute(CreateInquiryCommand)
→ CreateInquiryHandler.execute()
- Validate listing exists (Prisma)
- Create InquiryEntity
- Save to repository (Prisma)
- Publish InquiryCreatedEvent via EventBus
→ Return { id, listingId, createdAt }
```
**Marking as Read:**
```
PATCH /inquiries/:id/read (agent only)
→ InquiriesController.markAsRead()
→ CommandBus.execute(MarkInquiryReadCommand)
→ MarkInquiryReadHandler.execute()
- Find inquiry entity
- Verify agent is listing owner
- Call entity.markAsRead()
- Update in repository
- Publish InquiryReadEvent via EventBus
→ Return { success: true }
```
**Getting Inquiries:**
```
GET /inquiries/listing/:id or /agent/me (with pagination)
→ InquiriesController.getByListing() or getMyInquiries()
→ QueryBus.execute(GetInquiriesByListingQuery or GetInquiriesByAgentQuery)
→ Handler delegates to repository
→ Repository.findByListing() or findByAgent()
- Queries Prisma with joins
- Maps to InquiryReadDto
- Returns PaginatedResult
→ Return paginated data
```
---
## 🔑 KEY CLASSES & HANDLERS
### **Domain Entity: InquiryEntity**
```typescript
export class InquiryEntity extends AggregateRoot<string> {
// Properties
private _listingId: string;
private _userId: string;
private _message: string;
private _phone: string | null;
private _isRead: boolean;
// Factory Method
static createNew(id, listingId, userId, message, phone): InquiryEntity
Creates new inquiry with isRead=false
Emits InquiryCreatedEvent
// Business Logic
markAsRead(): void
Sets isRead to true
Emits InquiryReadEvent
}
```
### **Command Handlers**
#### CreateInquiryHandler
```typescript
class CreateInquiryHandler implements ICommandHandler<CreateInquiryCommand> {
async execute(command: CreateInquiryCommand): Promise<CreateInquiryResult> {
// 1. Validate listing exists
const listing = await prisma.listing.findUnique(...)
if (!listing) throw NotFoundException
// 2. Create entity with factory
const inquiry = InquiryEntity.createNew(...)
// 3. Persist to database
await inquiryRepo.save(inquiry)
// 4. Publish domain events
const events = inquiry.clearDomainEvents()
events.forEach(e => eventBus.publish(e))
return { id, listingId, createdAt }
}
}
```
#### MarkInquiryReadHandler
```typescript
class MarkInquiryReadHandler implements ICommandHandler<MarkInquiryReadCommand> {
async execute(command: MarkInquiryReadCommand): Promise<void> {
// 1. Load aggregate root
const inquiry = await inquiryRepo.findById(...)
if (!inquiry) throw NotFoundException
// 2. Verify authorization
const listing = await prisma.listing.findUnique(...)
const agent = await prisma.agent.findUnique(...)
if (agent.id !== listing.agentId) throw ForbiddenException
// 3. Update domain state
inquiry.markAsRead()
// 4. Persist state
await inquiryRepo.markAsRead(...)
// 5. Publish events
const events = inquiry.clearDomainEvents()
events.forEach(e => eventBus.publish(e))
}
}
```
### **Query Handlers**
#### GetInquiriesByListingHandler
```typescript
class GetInquiriesByListingHandler implements IQueryHandler<GetInquiriesByListingQuery> {
async execute(query: GetInquiriesByListingQuery): Promise<PaginatedResult<InquiryReadDto>> {
return this.inquiryRepo.findByListing(
query.listingId,
query.page,
query.limit
)
}
}
```
#### GetInquiriesByAgentHandler
```typescript
class GetInquiriesByAgentHandler implements IQueryHandler<GetInquiriesByAgentQuery> {
async execute(query: GetInquiriesByAgentQuery): Promise<PaginatedResult<InquiryReadDto>> {
// 1. Resolve agent ID from user ID
const agent = await prisma.agent.findUnique({ where: { userId } })
if (!agent) throw NotFoundException
// 2. Delegate to repository
return this.inquiryRepo.findByAgent(agent.id, page, limit)
}
}
```
### **Repository Implementation**
#### PrismaInquiryRepository
**Methods:**
1. `findById(id)` - Single inquiry lookup
2. `save(entity)` - Create inquiry
3. `markAsRead(id)` - Update isRead flag
4. `findByListing(listingId, page, limit)` - Paginated search with joins
5. `findByAgent(agentId, page, limit)` - Paginated search via listing agent
6. `countUnreadByAgent(agentId)` - Unread count aggregation
**Prisma Relations Used:**
- `inquiry.listing` → property (for title)
- `inquiry.user` → fullName, phone
- `listing.agentId` → agent filter
- Pagination: skip/take with orderBy descending

## 🎓 ARCHITECTURAL INSIGHTS
### **Strengths**
1. **Clean Architecture** - Clear separation of concerns across layers
2. **CQRS Pattern** - Separate read/write paths enable scalability
3. **Domain-Driven Design** - Business logic in entities, not anemic models
4. **Event-Driven** - Domain events enable audit trails and event sourcing
5. **Testability** - Each layer independently testable with mocks
6. **Type Safety** - Full TypeScript with interfaces and strict types
7. **DI Framework** - NestJS provides dependency injection out of box
### **Design Decisions**
1. **InquiryEntity as Aggregate Root**
- Encapsulates inquiry business rules
- Controls state transitions via methods (createNew, markAsRead)
- Collects domain events
2. **Repository Pattern**
- Interface in domain, implementation in infrastructure
- Allows swapping data sources without affecting business logic
3. **Separate Read/Write DTOs**

|----------|------|------|-------|
| `POST /inquiries` | JWT | Any | - |
| `GET /listing/:id` | JWT | Any | page, limit |
| `GET /agent/me` | JWT | AGENT | page, limit |
| `PATCH /:id/read` | JWT | AGENT | - |
**Permission Checks:**
- MarkInquiryReadHandler: Verifies user is agent, agent owns listing
---
## 🎯 DDD PRINCIPLES
### Domain Entity Encapsulation
```typescript
// Factory method (controlled creation)
static createNew(id, listingId, userId, message, phone): InquiryEntity
Creates entity with isRead=false
Emits InquiryCreatedEvent
// Domain methods (state transitions)
markAsRead(): void
Sets isRead=true
Emits InquiryReadEvent
```
### Repository Pattern
- **Interface in Domain** → `IInquiryRepository`
- **Implementation in Infrastructure** → `PrismaInquiryRepository`
- **Dependency Injection** → `INQUIRY_REPOSITORY` symbol
### Separate Read/Write Models
- **Write Model:** `InquiryEntity` (aggregate)
- **Read Model:** `InquiryReadDto` (query DTO)
---
## 🔄 Domain Events
| Event | When | Data |
|-------|------|------|
| **InquiryCreatedEvent** | Inquiry created | aggregateId, listingId, userId |
| **InquiryReadEvent** | Marked as read | aggregateId, listingId, userId |
---
## 💾 Database Operations
**Prisma Models Used:**
- `inquiry` - Main entity
- `listing` - For foreign key & agent lookup
- `property` - For listing title
- `user` - For buyer name & phone
**Key Queries:**
- `inquiry.create()` - New inquiry
- `inquiry.update()` - Mark read
- `inquiry.findMany()` - Pagination
- `inquiry.count()` - Total count
---
## 🚀 Entry Points
```typescript
// Module export
export { InquiriesModule }
// Exported interfaces
export { INQUIRY_REPOSITORY, type IInquiryRepository }
export { InquiryEntity }
// Usage in other modules
import { InquiriesModule } from '@modules/inquiries'
```
---
## 🎓 Architecture Summary
```
CLEAN ARCHITECTURE with CQRS + DDD
Presentation Layer (Controllers + DTOs)
Application Layer (CQRS Handlers)
Domain Layer (Entities + Events + Interfaces)
Infrastructure Layer (Prisma Repository)
Database
```
**Key Characteristics:**
✅ Dependency Inversion - Domain defines contracts
✅ Separation of Concerns - Each layer has clear responsibility
✅ Testability - Mock implementations at each layer
✅ Event-Driven - Domain events for audit & integration
✅ CQRS - Separate commands & queries for scalability
✅ Type Safety - Full TypeScript with strict interfaces
---
## 📌 Common Patterns
**Command Pattern:**
```typescript
// Send command
commandBus.execute(new CreateInquiryCommand(...))
// Handler processes
@CommandHandler(CreateInquiryCommand)
class CreateInquiryHandler { ... }
```
**Query Pattern:**
```typescript
// Send query
queryBus.execute(new GetInquiriesByListingQuery(...))
// Handler processes
@QueryHandler(GetInquiriesByListingQuery)
class GetInquiriesByListingHandler { ... }
```
**Dependency Injection Pattern:**
```typescript
@Injectable()
export class Handler {
constructor(
@Inject(INQUIRY_REPOSITORY) private repo: IInquiryRepository,
private prisma: PrismaService,
) {}
}
```
---
## 🔍 Where to Look For...

└─ Usage: <Button variant="default" size="lg" />
ui/badge.tsx
├─ CVA variants
│ ├─ default (primary)
│ ├─ secondary
│ ├─ outline
│ └─ ...colors (success, warning, info)
└─ Usage: <Badge variant="secondary">Text</Badge>
```
---
## 📊 State Management Patterns
### Gallery Local State
```
Component: ImageGallery
State: selectedIndex (number)
├─ Initialize: 0
├─ Update on: prev, next, thumbnail click

```
### Global State (Zustand)
```
Auth Store
├─ user: UserProfile | null
├─ isAuthenticated: boolean
├─ isLoading: boolean
├─ error: string | null
└─ Actions: login, logout, fetchProfile
Comparison Store
├─ selectedIds: string[] (persisted)
├─ listings: ListingDetail[]
├─ isLoading: boolean
├─ error: string | null
└─ Actions: addToCompare, removeFromCompare, etc.

## 📈 Component Complexity Levels
### Level 1: Simple UI Components
```
Badge, Button, Input, Label
├─ Props: basic props + variants
├─ State: none
└─ Interactions: click, focus, hover
```
### Level 2: Composite Components
```
Card (Header + Content + Footer)
ImageUpload (Drag-drop + Preview grid)
├─ Props: content children
├─ State: local state
└─ Interactions: click, drag, input
```
### Level 3: Feature Components
```
ImageGallery (Main + Thumbnails)
PropertyCard (Link + Image + Info)
├─ Props: data + callbacks
├─ State: selected index, UI state
└─ Interactions: navigation, filtering
```
### Level 4: Page Components
```
ListingDetailClient (Full page layout)
├─ Props: listing data
├─ State: multiple features
├─ Interactions: all user interactions
└─ Children: multiple feature components
```
---
## 🚀 Performance Considerations
### Image Optimization
```
Image Component Strategy:
├─ Next.js Image component
│ ├─ Automatic format selection (WebP, AVIF)
│ ├─ Responsive serving via srcset
│ └─ On-demand resizing
├─ Lazy Loading
│ ├─ Main image: priority={selectedIndex === 0}
│ └─ Thumbnails: no priority (lazy)
└─ Responsive Sizing
├─ sizes prop: tells browser image dimensions
└─ Prevents layout shift
```
### Code Splitting
```
Dynamic Imports:
├─ ListingMap (heavy, maps library)
│ ├─ ssr: false (client-only)
│ └─ loading: placeholder component
└─ Other components: bundled with page
```
### State Optimization
```
Zustand:
├─ Selector pattern: useStore(state => state.field)
├─ Only re-render on selected state change
└─ Persist middleware: localStorage only on needed data
```
---
## 🔄 Navigation Flow
### User Journey - Image Gallery
```
1. User visits /vi/listings/123
└─ Page loads with first image (priority=true)
2. User interacts with gallery:
├─ Click thumbnail
│ └─ setSelectedIndex(index) → main image updates
├─ Click next button
│ └─ setSelectedIndex(i + 1) → wraps to 0
└─ Click prev button
└─ setSelectedIndex(i - 1) → wraps to last
```
### User Journey - File Upload (Create/Edit Listing)
```
1. User opens listing form
└─ ImageUpload component mounts
2. User adds images:
├─ Drag & drop files
│ └─ addFiles() → filter + validate → onChange()
└─ Click to browse
└─ Select files → same as drag & drop
3. User removes image:
└─ removeImage(index) → cleanup URL → onChange()
4. User submits form:
└─ Images uploaded via listingsApi.uploadMedia()
```

## 💡 Tips & Best Practices
### Image Optimization
- Always use `sizes` prop with Next.js Image
- Set `priority={true}` only for above-fold images
- Use aspect ratio containers to prevent layout shift
- Let Next.js handle format selection (WebP, AVIF)
### Component Design
- Keep components focused (single responsibility)
- Use CVA for variant management
- Use composition over inheritance
- Keep local state for UI, global for app state
### State Management
- Use Zustand for global state (auth, comparison)
- Use local React state for component UI (gallery index)
- Use React Query for server state
- Persist only essential data to localStorage
### Testing
- Mock Next.js Image component
- Test responsive behavior
- Test edge cases (empty state, many images)
- Mock Zustand stores

## 1. Property Detail Page Structure
### File Location
```
apps/web/app/[locale]/(public)/listings/[id]/
├── page.tsx # Server component - fetches data, generates metadata, JSON-LD
└── (referenced) listing-detail-client.tsx # Client component - handles interactivity
```
### Page Architecture
**Server Component** (`page.tsx`):
- Fetches listing data via `fetchListingById(params.id)`
- Generates SEO metadata (Open Graph, Twitter Cards, canonical URLs)
- Generates JSON-LD structured data (breadcrumbs, property schema)
- Renders structured data and passes data to client component
**Client Component** (`listing-detail-client.tsx`):
- All interactivity (image gallery state, forms, etc.)
- Uses dynamic imports for heavy components (ListingMap)
- Main sections:
- Breadcrumb navigation
- Header with title, price, badges
- **Image Gallery** (main content area)
- Quick stats bar (area, bedrooms, bathrooms, floors, direction)
- Two-column layout:
- Left (2/3): Description, Details, Amenities, Map, Contact Card
- Right (1/3): Sticky sidebar with contact info, AI Estimate, Stats
### Data Flow
```
page.tsx (Server)
└─> fetchListingById() ─> ListingDetail object
└─> generateMetadata() ─> SEO metadata
└─> ListingDetailClient (Client)
└─> ImageGallery component
└─> AddToCompareButton component
└─> AiEstimateButton component
└─> dynamic ListingMap component
```

## 2. Property Images - Current Implementation
### Image Gallery Component
**File**: `apps/web/components/listings/image-gallery.tsx`
#### Features:
- **Main Display**:
- Aspect ratio: 16:9 (aspect-video)
- Uses Next.js `Image` component with `fill` layout
- Object fit: cover
- Rounded corners
- Previous/Next navigation buttons (semi-transparent overlay, hover effects)
- Current image counter (bottom-right: "X / Total")
- **Thumbnail Navigation**:
- Horizontal scrollable row (flex with overflow-x-auto)
- Each thumbnail: 64px × 64px (h-16 w-16)
- Border indicates selected state (2px border-primary vs border-transparent with opacity)
- Smooth transitions
- **Empty State**:
- Falls back to gray placeholder if no images: "Chưa có hình ảnh"
#### State Management:
- Local React state (`selectedIndex`): Tracks which image is displayed
- One-way: thumbnail click → main image update
#### Image Handling:
- Filters media by `type === 'image'`
- Sorts by `order` property
- Supports captions (from `PropertyMedia.caption`)
- Uses `next/image` with optimized sizes
#### Technical Details:
```typescript
interface PropertyMedia {
id: string;
url: string;
type: 'image' | 'video';
order: number;
caption: string | null;
}
```
### Image Upload Component
**File**: `apps/web/components/listings/image-upload.tsx`
#### Features:
- Drag & drop zone
- Click to browse
- File validation:
- Allowed types: JPEG, PNG, WebP
- Max size: 10MB per file
- Max files: 20
- Preview grid (2 cols mobile, 3 cols tablet, 4 cols desktop)
- Delete button on hover
- First image labeled "Ảnh bìa" (Cover photo)
- URL.createObjectURL for previews (properly cleaned up on unmount)
#### State Management:
- Local state: `ImageFile[]` (file + preview URL)
- onChange callback pattern

## 3. Image-Related Components
### Current Locations:
```
apps/web/components/
├── listings/
│ ├── image-gallery.tsx ✓ Main image display with thumbnails
│ ├── image-upload.tsx ✓ Upload with drag-drop
│ ├── listing-detail-client.tsx ✓ Uses image gallery
│ └── ...other listing components
├── ui/
│ ├── button.tsx ✓ Navigation buttons

```
### Property Card (Search/Listing View)
**File**: `apps/web/components/search/property-card.tsx`
- Uses first media item (`media[0]?.url`)
- Shows badge indicating total media count if > 1
- Has hover scale effect (group-hover:scale-105)
- Aspect ratio options: 16/10 (compact) or 4/3 (default)
---
## 4. Project Component Structure & Patterns
### Design System Approach
- **UI Components**: Located in `components/ui/`
- **Pattern**: CVA (class-variance-authority) for variants
- **Example** (button.tsx):
```typescript
const buttonVariants = cva(
'inline-flex items-center justify-center ...',
{
variants: {
variant: { default: '...', outline: '...', ghost: '...', ... },
size: { default: '...', sm: '...', lg: '...', icon: '...' },
},
defaultVariants: { variant: 'default', size: 'default' },
}
);
```
### Composition Pattern
- Small, focused components
- Props-based configuration
- Utility function composition (`cn()` from `@/lib/utils` - likely clsx + tailwind-merge)
- Forward refs for form components
### Dialog Component
**File**: `apps/web/components/ui/dialog.tsx`
- Custom implementation (not Radix)
- Features:
- Backdrop overlay (fixed, z-50, black/80)
- Center content positioning
- Close on backdrop click
- Body overflow hidden when open
- Composable parts: Dialog, DialogContent, DialogHeader, DialogTitle, DialogDescription, DialogFooter
---
## 5. Next.js Image Usage Patterns
### Configuration
**File**: `apps/web/next.config.js`
```javascript
images: {
remotePatterns: [
{ protocol: 'https', hostname: '**' }, // All HTTPS domains allowed
],
}
```
### Usage Pattern in Components:
```typescript
import Image from 'next/image';
// Main image (fill layout)
<Image
src={images[selectedIndex]?.url ?? ''}
alt={`Ảnh ${selectedIndex + 1}`}
fill
sizes="(max-width: 768px) 100vw, 60vw"
className="object-cover"
priority={selectedIndex === 0}
/>
// Thumbnail (fixed size)
<Image
src={img.url}
alt={`Thumbnail ${index + 1}`}
fill
sizes="64px"
className="object-cover"
/>
// Property card (fill layout)
<Image
src={listing.property.media[0]?.url ?? ''}
alt={`Ảnh bất động sản: ${listing.property.title}`}
fill
sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
className="object-cover transition-transform group-hover:scale-105"
/>
```
### Best Practices Observed:
✓ Always provide `alt` text
✓ Use responsive `sizes` prop
✓ Use `fill` layout with `object-cover`
✓ Set `priority={true}` for above-fold images
✓ Use aspect ratio containers (aspect-video, aspect-square, etc.)
---
## 6. State Management Patterns
### Using Zustand
#### Auth Store
**File**: `apps/web/lib/auth-store.ts`
```typescript
const useAuthStore = create<AuthState>((set, get) => ({
user: null,
isAuthenticated: false,
isLoading: false,
error: null,
login: async (data) => { /* ... */ },
logout: async () => { /* ... */ },
fetchProfile: async () => { /* ... */ },
initialize: async () => { /* ... */ },
}));
```
#### Comparison Store (with persistence)
**File**: `apps/web/lib/comparison-store.ts`
```typescript
export const useComparisonStore = create<ComparisonState>()(
persist(
(set, get) => ({
selectedIds: [],
listings: [],
isLoading: false,
error: null,
addToCompare: (id: string) => { /* ... */ },
removeFromCompare: (id: string) => { /* ... */ },
isSelected: (id: string) => { /* ... */ },
setListings: (listings: ListingDetail[]) => { /* ... */ },
setLoading: (loading: boolean) => { /* ... */ },
setError: (error: string | null) => { /* ... */ },
}),
{
name: 'goodgo-compare',
partialize: (state) => ({ selectedIds: state.selectedIds }),
}
)
);
```
### Store Patterns:
- **Actions as methods** in store object
- **Async support** with `set()` and `get()`
- **Persistence middleware** for localStorage (comparison store)
- **Error handling** with dedicated error fields
- **Loading states** for async operations
### Hooks Pattern
**File**: `apps/web/lib/hooks/`
```
use-analytics.ts
use-listings.ts # Likely wraps API calls
use-payments.ts
use-saved-searches.ts
use-subscription.ts
use-valuation.ts
```
These likely use React Query + custom Zustand stores

## 11. Key Insights & Best Practices
### Image Strategy
1. **Responsive Images**: Uses `sizes` prop for responsive serving
2. **Lazy Loading**: Non-priority images load on demand
3. **Performance**: Object-fit cover with aspect ratios
4. **SEO**: First image used for OG tags in metadata
5. **No 3rd-party**: Custom gallery implementation = lightweight
### Component Architecture
1. **Separation of Concerns**: Server fetch → Client interactivity
2. **Dynamic Imports**: Heavy components (Map) loaded on demand
3. **Composition**: Small, reusable UI components with variants
4. **Type Safety**: Full TypeScript with Zod validation
### State Management
1. **Zustand for Global State**: Auth, Comparisons
2. **React Query**: Likely for server state (data fetching)
3. **Local State**: For UI state (gallery index, form inputs)
### i18n
- Vietnamese (vi) and English (en) support
- Labels: `@/lib/validations/listings` for property types, directions, etc.
### SEO
- JSON-LD schema for listings and breadcrumbs
- Open Graph and Twitter Cards
- Canonical URLs
- Alternate language links
---
## 12. Dependencies Not Present
⚠️ **Potential Opportunities** (if needed):
- No full-featured carousel library (could use embla-carousel if complex carousel needed)
- No lightbox library (current implementation is basic - consider if modal zoom needed)
- No image optimization service (relying on Next.js Image component)
- No form builder library (using react-hook-form + manual forms)
- No animation library (using Tailwind animations)
- No virtualization (could add if listing 1000s of items)

## 🖼️ Working with Images
### Current Gallery Features
```typescript
// apps/web/components/listings/image-gallery.tsx
interface ImageGalleryProps {
media: PropertyMedia[];
className?: string;
}
// Features:
// ✓ Main image (16:9 aspect ratio)
// ✓ Previous/Next buttons
// ✓ Image counter badge
// ✓ Horizontal scrollable thumbnails (64x64px)
// ✓ Selected state highlighting
// ✓ Empty state fallback
```
### Data Structure
```typescript
interface PropertyMedia {
id: string;
url: string; // Full URL to image
type: 'image' | 'video'; // Media type filter
order: number; // Sort order (0, 1, 2...)
caption: string | null; // Optional caption
}
interface Property {
// ... other fields
media: PropertyMedia[]; // Array of images/videos
}
```
### Using Images in Components
```typescript
// ✓ Import Next.js Image
import Image from 'next/image';
// ✓ Main image with fill layout (responsive)
<Image
src={images[index]?.url}
alt={`Image ${index + 1}`}
fill
sizes="(max-width: 768px) 100vw, 60vw"
className="object-cover"
priority={index === 0}
/>
// ✓ Fixed-size thumbnail
<Image
src={img.url}
alt={`Thumbnail ${i}`}
fill
sizes="64px"
className="object-cover"
/>
// ✓ Responsive property card
<Image
src={media[0]?.url}
alt="Property"
fill
sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
className="object-cover transition-transform group-hover:scale-105"
/>
```
### Image Upload API
```typescript
// From: apps/web/lib/listings-api.ts
const listingsApi = {
uploadMedia: async (
listingId: string,
file: File,
caption?: string
) => {
const formData = new FormData();
formData.append('file', file);
if (caption) formData.append('caption', caption);
// POST /api/v1/listings/{listingId}/media
// Returns: { mediaId: string; url: string }
},
};
```
### File Upload Component (for reference)
```typescript
// apps/web/components/listings/image-upload.tsx
interface ImageFile {
file: File;
preview: string;
}
// Usage:
<ImageUpload
images={images}
onChange={(newImages) => setImages(newImages)}
maxFiles={20}
/>
// Validation:
// ✓ Types: JPEG, PNG, WebP
// ✓ Max size: 10MB per file
// ✓ Max count: 20 files
// ✓ Drag & drop support
// ✓ Preview grid with delete button
```

## 🎨 Styling Patterns
### Aspect Ratios (Tailwind)
```html
<!-- 16:9 (videos, main images) -->
<div class="aspect-video"><!-- 1.777:1 --></div>
<!-- 4:3 (property cards) -->
<div class="aspect-[4/3]"><!-- 1.333:1 --></div>
<!-- 16:10 (compact property cards) -->
<div class="aspect-[16/10]"><!-- 1.6:1 --></div>
<!-- Square (thumbnails) -->
<div class="aspect-square"><!-- 1:1 --></div>
```
### Image Container Pattern
```jsx
<div className="relative aspect-video overflow-hidden rounded-lg bg-muted">
<Image
src={url}
alt="description"
fill
sizes="(max-width: 768px) 100vw, 60vw"
className="object-cover"
priority={isMainImage}
/>
</div>
```
### Common Tailwind Classes
```
// Layout
aspect-video # 16:9 ratio
aspect-square # 1:1 ratio
relative / absolute # Positioning
fill # Object-fit with aspect ratio
// Styling
object-cover # Image fit (crop to fill)
object-contain # Image fit (preserve ratio)
rounded-lg # Border radius
bg-muted # Placeholder background
// Interactive
transition-colors # Smooth color changes
group-hover:scale-105 # Hover effect
opacity-70 # Partial transparency
// Overlay
absolute inset-0 # Full coverage overlay
bg-black/50 # Semi-transparent black
hover:bg-black/70 # Darker on hover
```
---
## 🔄 State Management
### Zustand Store Pattern
```typescript
import { create } from 'zustand';
import { persist } from 'zustand/middleware';
// Simple store
const useMyStore = create<MyState>((set, get) => ({
count: 0,
increment: () => set((state) => ({ count: state.count + 1 })),
asyncAction: async () => {
set({ isLoading: true });
// ... async work
set({ data: result, isLoading: false });
},
}));
// Store with persistence
const useComparisonStore = create<State>()(
persist(
(set, get) => ({
// store logic
}),
{
name: 'storage-key',
partialize: (state) => ({ selectedIds: state.selectedIds }),
}
)
);
// Usage in component
const count = useMyStore((state) => state.count);
const increment = useMyStore((state) => state.increment);
```
### Image Gallery Local State
```typescript
const [selectedIndex, setSelectedIndex] = React.useState(0);
const handleNext = () => {
setSelectedIndex((i) => (i < images.length - 1 ? i + 1 : 0));
};
const handlePrev = () => {
setSelectedIndex((i) => (i > 0 ? i - 1 : images.length - 1));
};
```
---
## 🧩 UI Component Patterns
### Button Component (with variants)
```typescript
// From: apps/web/components/ui/button.tsx
import { Button } from '@/components/ui/button';
// Variants:
<Button variant="default">Default</Button> // Primary
<Button variant="outline">Outline</Button> // Border
<Button variant="secondary">Secondary</Button> // Secondary color
<Button variant="destructive">Delete</Button> // Red
<Button variant="ghost">Ghost</Button> // No background
<Button variant="link">Link</Button> // Text link
// Sizes:
<Button size="default">Default</Button> // 40px height
<Button size="sm">Small</Button> // 36px height
<Button size="lg">Large</Button> // 44px height
<Button size="icon">Icon</Button> // Square button
```
### Badge Component (with variants)
```typescript
import { Badge } from '@/components/ui/badge';
<Badge variant="default">Primary</Badge>
<Badge variant="secondary">Secondary</Badge>
<Badge variant="outline">Outline</Badge>
<Badge variant="destructive">Destructive</Badge>
<Badge variant="success">Success</Badge>
<Badge variant="warning">Warning</Badge>
<Badge variant="info">Info</Badge>
```
### Card Component
```typescript
import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
<Card>
<CardHeader>
<CardTitle>Title</CardTitle>
</CardHeader>
<CardContent>
{/* content */}
</CardContent>
</Card>
```
### Dialog/Modal Pattern
```typescript
import { Dialog, DialogContent, DialogHeader, DialogTitle } from '@/components/ui/dialog';
const [isOpen, setIsOpen] = React.useState(false);
<Dialog open={isOpen} onOpenChange={setIsOpen}>
<DialogContent>
<DialogHeader>
<DialogTitle>Dialog Title</DialogTitle>
</DialogHeader>
{/* content */}
</DialogContent>
</Dialog>
```
---
## 📱 Responsive Design
### Breakpoints
```css
xs: 0px /* Default */
sm: 640px /* Mobile landscape */
md: 768px /* Tablet */
lg: 1024px /* Desktop */
xl: 1280px /* Wide desktop */
2xl: 1536px /* Ultra-wide */
```
### Common Patterns
```jsx
// Mobile-first
<div className="w-full sm:w-1/2 md:w-1/3 lg:w-1/4">
// Conditional display
<div className="hidden md:block">Show on tablet+</div>
<div className="block md:hidden">Show on mobile</div>
// Responsive grid
<div className="grid grid-cols-2 sm:grid-cols-3 md:grid-cols-4 gap-4">
// Responsive text size
<p className="text-sm md:text-base lg:text-lg">
// Responsive padding
<div className="p-4 sm:p-6 md:p-8">
```
---
## 🔗 Common Imports
### Essential Imports
```typescript
// Components
import Image from 'next/image';
import Link from 'next/link';
import dynamic from 'next/dynamic';
// UI Components
import { Button } from '@/components/ui/button';
import { Badge } from '@/components/ui/badge';
import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
import { Dialog, DialogContent, DialogHeader, DialogTitle } from '@/components/ui/dialog';
// Utilities
import { cn } from '@/lib/utils';
import { formatPrice, formatPricePerM2 } from '@/lib/currency';
// State & API
import { useAuthStore } from '@/lib/auth-store';
import { useComparisonStore } from '@/lib/comparison-store';
import { listingsApi } from '@/lib/listings-api';
// Hooks
import * as React from 'react';
import { useCallback, useEffect, useState } from 'react';
```
---
## 📊 Data Fetching
### Server-side Fetching
```typescript
// apps/web/lib/listings-server.ts
import { fetchListingById } from '@/lib/listings-server';
// In page.tsx (Server Component)
const listing = await fetchListingById(params.id);
if (!listing) notFound();
```
### Client-side API
```typescript
// apps/web/lib/listings-api.ts
import { listingsApi } from '@/lib/listings-api';
// Usage:
const listing = await listingsApi.getById(id);
const results = await listingsApi.search({ city: 'Ho Chi Minh' });
```
### React Query Usage (likely)
```typescript
// Typical pattern for fetching
import { useQuery } from '@tanstack/react-query';
const { data, isLoading, error } = useQuery({
queryKey: ['listing', id],
queryFn: () => listingsApi.getById(id),
});
```
---
## 🌐 Internationalization
### Language Support
- Vietnamese (vi)
- English (en)
### Using i18n
```typescript
// In components, use Vietnamese labels directly or from constants
const PROPERTY_TYPES: Record<string, string> = {
APARTMENT: 'Căn hộ',
HOUSE: 'Nhà riêng',
VILLA: 'Biệt thự',
// ...
};
// From @/lib/validations/listings
import { PROPERTY_TYPES, DIRECTIONS, TRANSACTION_TYPES } from '@/lib/validations/listings';
```
### Language-aware Routes
```
/vi/listings/123 # Vietnamese
/en/listings/123 # English
```
---
## 🔐 Security Features
### CSP Headers (next.config.js)
```javascript
img-src 'self' data: blob: https://*.mapbox.com https://
font-src 'self' data:
```
### Image Domain Whitelist
```javascript
// Allows HTTPS images from any domain
remotePatterns: [
{ protocol: 'https', hostname: '**' }
]
```
---
## 🧪 Testing Considerations
### Component Files to Test
- `image-gallery.tsx` - Gallery navigation, state changes
- `image-upload.tsx` - File validation, drag-drop
- `property-card.tsx` - Image display, responsive
- `listing-detail-client.tsx` - Overall page functionality
### Test Patterns
```typescript
// Mock Next.js Image component
jest.mock('next/image', () => ({
__esModule: true,
default: (props) => <img {...props} />,
}));
// Mock Zustand stores
jest.mock('@/lib/auth-store', () => ({
useAuthStore: jest.fn(),
}));
```
---
## 🚀 Performance Optimization Tips
1. **Image Priority**
```typescript
priority={selectedIndex === 0} // First image loads with page
```
2. **Responsive Sizes**
```typescript
sizes="(max-width: 768px) 100vw, 60vw" // Tells browser image width
```
3. **Lazy Loading**
- Thumbnails load on demand (no priority set)
- Reduces initial page weight
4. **Dynamic Imports**
```typescript
const ListingMap = dynamic(() => import('@/components/map/listing-map'), {
ssr: false,
loading: () => <div>Loading...</div>,
});
```
5. **Object URLs Cleanup**
```typescript
React.useEffect(() => {
return () => {
images.forEach((img) => URL.revokeObjectURL(img.preview));
};
}, []);
```
---
## 📋 Common Tasks
### Add a New UI Element
1. Create in `components/ui/ComponentName.tsx`
2. Use CVA for variants
3. Export from the same file
4. Import and use in feature components
### Add a New Feature Component
1. Create in `components/feature-name/ComponentName.tsx`
2. Make 'use client' if interactive
3. Import UI components
4. Use Zustand stores if needed global state
5. Use local state for UI state
### Modify Image Gallery
1. Edit `components/listings/image-gallery.tsx`
2. Update PropertyMedia interface if needed (in `lib/listings-api.ts`)
3. Adjust aspect ratio / sizes as needed
4. Test responsive behavior
### Add Image Lightbox
1. Choose library (embla-carousel, yet-another-react-lightbox, etc.)
2. Install: `pnpm add package-name -F @goodgo/web`
3. Create wrapper component in `components/listings/image-lightbox.tsx`
4. Integrate with `image-gallery.tsx`
5. Test with multiple images
---
## 🐛 Common Issues & Solutions
### Image Not Loading
- Check URL is valid and HTTPS
- Verify domain in `remotePatterns`
- Check CSP headers allow the domain
### Gallery Navigation Frozen
- Check `selectedIndex` state updates
- Verify onClick handlers are properly bound
- Check for JavaScript errors in console
### Thumbnail Scroll Issues
- Ensure parent container has `overflow-x-auto`
- Check flex properties on thumbnails
- Verify width constraints (flex-shrink-0)
### Layout Shifting on Image Load
- Use aspect ratio container
- Set explicit width/height
- Use `fill` layout with container

3. Use **TEST_TEMPLATES.md** as implementation guide
4. Reference the example test patterns in the Analysis document
## File Organization by Module
### Inquiries Module (4 files)
```
✗ prisma-inquiry.repository.ts — 6 methods, pagination, relationships
✗ inquiries.controller.ts — 4 endpoints, guards
✗ create-inquiry.dto.ts — 3 validations
✗ list-inquiries.dto.ts — 2 validations (pagination)
```
### Leads Module (6 files)
```
✗ prisma-lead.repository.ts — 6 methods, stats aggregation
✗ lead-score.vo.ts — Range validation (0-100)
✗ leads.controller.ts — 5 endpoints, role guards
✗ create-lead.dto.ts — 6 validations
✗ list-leads.dto.ts — Status enum, pagination
✗ update-lead-status.dto.ts — Status enum
```
### Reviews Module (5 files)
```
✗ prisma-review.repository.ts — 7 methods, distribution stats
✗ rating.vo.ts — Integer range validation (1-5)
✗ reviews.controller.ts — 5 endpoints, mixed auth
✗ create-review.dto.ts — 4 validations
✗ list-reviews.dto.ts — 2 DTO classes, pagination
```
## Testing Priority Levels
### 🔴 CRITICAL (Business Logic)
1. **PrismaReviewRepository.getStats()** — Distribution calculation is complex
2. **PrismaLeadRepository.getStatsByAgent()** — Conversion rate formula
3. **Rating.vo** — Must validate 1-5 integers only
4. **LeadScore.vo** — Must validate 0-100 range
**Start here** — These are the most business-critical validations
### 🟡 HIGH (Data Integrity)
1. Repository CRUD operations
2. Pagination calculations
3. Relationship mapping (user joins, listing traversal)
4. Controller command/query dispatch
**Test second** — These ensure data consistency
### 🟢 MEDIUM (Validation & Guards)
1. DTO field validations
2. Enum constraints
3. Optional field handling
4. Authentication/Authorization guards
**Test last** — These are framework-level concerns
## Test Execution Roadmap
### Week 1: Value Objects & DTOs (8-10 test files)
- [ ] LeadScore.vo.ts (1 file, 4-5 test cases)
- [ ] Rating.vo.ts (1 file, 4-5 test cases)
- [ ] All 10 DTO files (using templates, minimal variations)
**Estimated time:** 3-5 hours total
### Week 2: Controllers (2 test files)
- [ ] InquiriesController (4 endpoints + guards)
- [ ] LeadsController (5 endpoints + guards)
- [ ] ReviewsController (5 endpoints + mixed auth)
**Estimated time:** 2-3 hours total
### Week 3: Repositories (3 test files)
- [ ] PrismaInquiryRepository (6 methods)
- [ ] PrismaLeadRepository (6 methods + aggregation)
- [ ] PrismaReviewRepository (7 methods + distribution)
**Estimated time:** 4-6 hours total
### Total Estimated Time: 9-14 hours
## Key Testing Patterns
### Repositories
```typescript
// Mock all Prisma methods in beforeEach
mockPrisma = {
[model]: {
findUnique: vi.fn(),
findMany: vi.fn(),
create: vi.fn(),
update: vi.fn(),
count: vi.fn()
}
};
// Test happy path and error cases
// Verify pagination calculations
// Verify data transformation (toDomain)
```
### Value Objects
```typescript
// Test valid cases
const result = ValueObject.create(validValue);
expect(result.isOk()).toBe(true);
// Test invalid cases
const result = ValueObject.create(invalidValue);
expect(result.isErr()).toBe(true);
expect(result.unwrapErr()).toBe('error message');
```
### DTOs
```typescript
// Use validate() from class-validator
const errors = await validate(dto);
expect(errors).toHaveLength(0); // or > 0 for invalid cases
// Test type transformation with class-transformer
// Test optional field handling
```
### Controllers
```typescript
// Mock CommandBus and QueryBus
mockCommandBus.execute.mockResolvedValue(expectedResult);
// Verify command/query construction
const command = mockCommandBus.execute.mock.calls[0][0];
expect(command.userId).toBe(expectedUserId);
```
## Critical Formulas to Test
### Pagination
```
skip = (page - 1) * take
totalPages = Math.ceil(total / take)
take = Math.min(limit, 100) // Clamped to 100 max
```
### Lead Statistics
```
conversionRate = (CONVERTED_count / total_leads) * 100 // 2 decimals
avgScore = (sum_of_scores / non_null_count) // 1 decimal, null if no scores
```
### Review Statistics
```
averageRating = (sum_of_ratings / total_reviews) // 1 decimal
distribution = { 1: count, 2: count, 3: count, 4: count, 5: count }
```
## Import Statements You'll Need
```typescript
// Testing utilities
import { describe, it, expect, beforeEach, vi } from 'vitest';
import { validate } from 'class-validator';
import { plainToClass } from 'class-transformer';
// NestJS utilities (for controller tests)
import type { EventBus, CommandBus, QueryBus } from '@nestjs/cqrs';
// Domain classes
import { InquiryEntity } from './domain/entities/inquiry.entity';
import { LeadEntity } from './domain/entities/lead.entity';
import { ReviewEntity } from './domain/entities/review.entity';
import { LeadScore } from './domain/value-objects/lead-score.vo';
import { Rating } from './domain/value-objects/rating.vo';
```
## Common Test Data
### User IDs
```
user-1, user-2, user-3, user-agent-1
```
### Lead Statuses
```
NEW, CONTACTED, QUALIFIED, NEGOTIATING, CONVERTED, LOST
```
### Pagination Defaults
```
page: 1, limit: 20 (max 100)
```
### Rating Range
```
1-5 stars (integer only)
```
### Lead Score Range
```
0-100 (any number)
```
## References
### Existing Test Files (Use as Reference)
- `src/modules/inquiries/application/__tests__/create-inquiry.handler.spec.ts` (20 lines pattern)
- `src/modules/leads/application/__tests__/create-lead.handler.spec.ts` (20 lines pattern)
- `src/modules/reviews/presentation/__tests__/reviews.controller.spec.ts` (135 lines pattern)
### Full Implementations
All 17 file implementations are in `TEST_COVERAGE_ANALYSIS.md` with line-by-line explanations.
## Troubleshooting
### Issue: "Cannot find module" when mocking
**Solution:** Use `as any` casting for mocked dependencies
```typescript
const repo = new PrismaInquiryRepository(mockPrisma as any);
```
### Issue: Validation tests not working
**Solution:** Make sure you're using `plainToClass` for DTOs with transformers
```typescript
const dto = plainToClass(CreateLeadDto, plainObject);
```
### Issue: Pagination calculations don't match
**Solution:** Remember that limit is clamped to 100
```typescript
const take = Math.min(limit, 100); // Always do this
```
### Issue: Stats calculations have rounding errors
**Solution:** Check decimal place requirements:
- conversionRate: 2 decimals (multiply by 10000, divide by 100)
- avgScore: 1 decimal (multiply by 10, divide by 10)
- averageRating: 1 decimal (multiply by 10, divide by 10)
## Next Steps
1. **Pick your starting file** from Week 1 (recommend LeadScore.vo first — simplest)
2. **Open the template** matching that file type in TEST_TEMPLATES.md
3. **Copy the template** to your test file location
4. **Adapt the template** with your specific imports and data
5. **Run tests** and verify they pass
6. **Move to next file** following the roadmap

## Quick Test Scenarios by Type
### REPOSITORIES (3 files)
Test checklist for each repository:
- [ ] findById() returns entity or null
- [ ] save() creates record with correct data mapping
- [ ] Paginated methods respect limit cap (100 max)
- [ ] Pagination calculation: skip = (page - 1) * take
- [ ] Relationships are joined correctly
- [ ] Aggregations calculate correctly (stats methods)
- [ ] Optional fields handling (null coercion)
- [ ] ISO date formatting in DTOs
**Specific to PrismaInquiryRepository:**
- countUnreadByAgent() aggregation
- findByListing() includes property.title
- findByAgent() joins through listing.agentId
**Specific to PrismaLeadRepository:**
- findByAgent() optional status filter
- getStatsByAgent() calculates:
- totalLeads count
- byStatus object (dict of counts)
- conversionRate: (CONVERTED / total) * 100 (2 decimals)
- avgScore: average of non-null scores (1 decimal)
**Specific to PrismaReviewRepository:**
- findByUserAndTarget() unique constraint query
- getStats() builds distribution object (keys 1-5)
- averageRating calculation: (sum / total) * 10 / 10 (1 decimal)
---
### VALUE OBJECTS (2 files)
Test checklist:
- [ ] create() with valid value returns Result.ok()
- [ ] create() with invalid value returns Result.err() with correct message
- [ ] Getter returns props.value
- [ ] Invalid cases covered (negative, > max, non-integer, null)
**LeadScore validation:**
```
✓ Valid: 0, 50, 100
✗ Invalid: -1, 101, 2.5, null, "50"
Error: "Điểm lead phải từ 0 đến 100"
```
**Rating validation:**
```
✓ Valid: 1, 2, 3, 4, 5
✗ Invalid: 0, 6, 2.5, null, "5"
Error: "Đánh giá phải từ 1 đến 5 sao"
```
---
### CONTROLLERS (2 files)
Test checklist:
- [ ] Each endpoint dispatches correct command/query type
- [ ] Parameters are mapped correctly from DTO
- [ ] Optional fields become null (e.g., phone ?? null → null)
- [ ] Default pagination values applied (page: 1, limit: 20)
- [ ] CurrentUser decorator extracts user.sub correctly
- [ ] Guard enforcement (@UseGuards, @Roles)
- [ ] Return types match (e.g., { deleted: true })
**InquiriesController specifics:**
- POST /inquiries: phone optional → null
- GET /inquiries/listing/:listingId: requires JWT
- GET /inquiries/agent/me: requires JWT + AGENT role
- PATCH /inquiries/:id/read: requires JWT + AGENT role
**LeadsController specifics:**
- ALL endpoints require JWT + AGENT role (class-level @Roles)
- POST /leads: score optional, score range validation in command
- GET /leads: status filter optional
- GET /leads/stats: aggregation query
- PATCH /leads/:id/status: only status field in command
- DELETE /leads/:id: agentId verification in command
**ReviewsController specifics:**
- POST /reviews: requires JWT (AuthGuard)
- GET /reviews: NO auth required (stats are public)
- GET /reviews/stats: NO auth required
- GET /reviews/me: requires JWT
- DELETE /reviews/:id: requires JWT + ownership check in command
---
### DTOs (10 files)
Test checklist:
- [ ] Required fields throw ValidationException if missing
- [ ] String max/min length validated
- [ ] Number min/max validated
- [ ] Enum @IsIn() validates allowed values
- [ ] Type transformation (class-transformer @Type)
- [ ] Email format validated (@IsEmail)
- [ ] Optional fields (@IsOptional) don't throw if omitted
**Pagination standard (used in 5 DTOs):**
- page: optional, @Min(1), default 1
- limit: optional, @Min(1), @Max(100), default 20
- Both use @Type(() => Number) for string→number transformation
**Enum validations:**
- LeadStatus: ['NEW', 'CONTACTED', 'QUALIFIED', 'NEGOTIATING', 'CONVERTED', 'LOST']
- Used in: ListLeadsDto, UpdateLeadStatusDto
---
## Test Priority Matrix
### 🔴 CRITICAL (Business Logic)
1. PrismaReviewRepository.getStats() - distribution calculation
2. PrismaLeadRepository.getStatsByAgent() - conversion rate formula
3. Rating.vo - must be 1-5 integers only
4. LeadScore.vo - must be 0-100 range
### 🟡 HIGH (Data Integrity)
1. All repository CRUD methods
2. Pagination calculations
3. Relationship mapping (user joins, listing joins)
4. Controller parameter mapping
### 🟢 MEDIUM (Validation)
1. DTO field validations
2. Enum constraints
3. Optional field handling
4. Guard enforcement
---
## Test Execution Order Recommendation
1. **Value Objects** (2 files) - 2 simple test files
2. **DTOs** (10 files) - Use class-validator testing patterns
3. **Controllers** (2 files) - Command/query dispatch tests
4. **Repositories** (3 files) - Data layer tests with mocked Prisma
---
## Mock Setup Template
### For Repositories:
```typescript
const mockPrisma = {
inquiry: { findUnique: vi.fn(), findMany: vi.fn(), create: vi.fn(), update: vi.fn(), delete: vi.fn(), count: vi.fn() },
};
const repo = new PrismaInquiryRepository(mockPrisma as any);
```
### For Controllers:
```typescript
const mockCommandBus = { execute: vi.fn() };
const mockQueryBus = { execute: vi.fn() };
const controller = new InquiriesController(mockCommandBus as any, mockQueryBus as any);
```
### For Value Objects:
```typescript
const result = LeadScore.create(75);
expect(result.isOk()).toBe(true);
expect(result.unwrap().value).toBe(75);
```
### For DTOs:
```typescript
import { validate } from 'class-validator';
const dto = new CreateLeadDto();
dto.name = 'Nguyễn Văn A';
dto.phone = '0901234567';
// ... set other required fields
const errors = await validate(dto);
expect(errors).toHaveLength(0);
```
---
## Key Formulas to Verify
### Pagination:
```
skip = (page - 1) * take
totalPages = Math.ceil(total / take)
take = Math.min(limit, 100)
```
### Lead Conversion Rate:
```
conversionRate = (convertedCount / totalLeads) * 100
Result: rounded to 2 decimals (e.g., 33.33)
```
### Lead Average Score:
```
avgScore = scoreSum / scoreCount (where score !== null)
Result: rounded to 1 decimal (e.g., 75.5)
```
### Review Average Rating:
```
averageRating = (sum / totalReviews)
Result: rounded to 1 decimal (e.g., 4.5)
```
### Review Distribution:
```
distribution: { 1: count, 2: count, 3: count, 4: count, 5: count }
Must initialize all 5 keys, even if 0
```

## Next Steps
1. **Copy reference test patterns:**
- Create inquiry and lead handlers already have good test patterns
- Controller test for reviews shows endpoint testing approach
2. **Start with repositories:**
- Most complex (Prisma mocking)
- Most critical (data layer)
- Established patterns in existing tests
3. **Test DTOs second:**
- Quick feedback (class-validator validation)
- 10 files but mostly simple
4. **Controllers and VOs last:**
- Build on repository/DTO tests
- Depend on handler tests (if testing full flow)

- Accessibility: aria-labels, semantic HTML, focus states
- All properly tested (9 test files for UI components)
**Feature Components (32 files):**
- Auth: OAuth buttons
- Charts: Price trends, agent performance, district heatmap, district bar chart
- Comparison: Add to compare button, floating bar, stats, table
- Listings: Image gallery, image upload, listing detail, multi-step form, status badges
- Map: Mapbox listing map with clustering
- Search: Filter bar, property cards, search results
- SEO: JSON-LD schema generation
- Valuation: AI estimate button, form, history, results
**All components follow:**
- ✅ TypeScript with strict typing
- ✅ React best practices (memoization where appropriate)
- ✅ Proper error boundaries (error.tsx files for each layout)
- ✅ Loading states (loading.tsx files)
- ✅ Responsive design (Tailwind CSS)
---
## 3. STATE MANAGEMENT
### Zustand Store Implementation
**2 Stores with Proper Typing & Persistence:**
#### Auth Store (`lib/auth-store.ts`)
```typescript
- user: UserProfile | null
- isAuthenticated: boolean
- isLoading: boolean
- error: string | null
```
**Methods:**
- login(data) - Phone/password authentication
- register(data) - New user signup
- handleOAuthCallback(token, refreshToken) - OAuth token exchange
- logout() - Clear session
- refreshToken() - Token refresh on 401
- fetchProfile() - Get current user
- initialize() - Check auth cookie on mount
- clearError() - Reset error state
**Features:**
- ✅ Automatic token refresh on 401 errors
- ✅ Profile re-fetch on successful auth
- ✅ Cookie-based authentication check
- ✅ Graceful logout handling (clears on API failure)
#### Comparison Store (`lib/comparison-store.ts`)
```typescript
- selectedIds: string[] (max 5 items)
- listings: ListingDetail[] (full listing data)
- isLoading: boolean
- error: string | null
```
**Methods:**
- addToCompare(id) - Add listing (max 5, returns boolean)
- removeFromCompare(id) - Remove listing
- isSelected(id) - Check if selected
- clearAll() - Reset
- canCompare() - Check if 2+ items
- canAdd() - Check if <5 items
- setListings() - Update data
- computeComparisonStats() - Calculate price/area ranges
**Features:**
- ✅ Persisted to localStorage (goodgo-compare)
- ✅ Type-safe statistics calculation
- ✅ Min/max comparison logic
- ✅ Error state management
---
## 4. API INTEGRATION
### API Client Architecture (`lib/api-client.ts`)
**Base URL:** `${NEXT_PUBLIC_API_URL}/api/v1` (default: `http://localhost:3001/api/v1`)
**Features:**
- ✅ Request method abstraction (GET, POST, PATCH, DELETE)
- ✅ Automatic CSRF token injection for non-safe methods
- ✅ JSON request/response handling
- ✅ Custom ApiError class with status codes
- ✅ Credentials included by default (cookies)
- ✅ Content-Type: application/json
**Error Handling:**
```typescript
class ApiError extends Error {
constructor(status: number, message: string)
}
```
### API Clients (10 Specialized Modules)
1. **auth-api.ts** - Register, login, refresh, logout, OAuth exchange, get profile
2. **listings-api.ts** - Search, create, get by ID, update status, upload media
3. **analytics-api.ts** - Market reports, heatmap data
4. **comparison-api.ts** - Get multiple listings for comparison
5. **payment-api.ts** - Payment processing
6. **profile-api.ts** - User profile management
7. **saved-search-api.ts** - Save/manage search queries
8. **subscription-api.ts** - Plan management
9. **valuation-api.ts** - AI property valuation
10. **admin-api.ts** - Dashboard stats, user list, moderation queue
### React Query Integration
**Custom Hooks (`lib/hooks/`):**
```typescript
- useListingsSearch(params) - Search listings with pagination
- useListingDetail(id) - Get single listing (enabled guard)
- useAnalytics() - Market analytics with caching
- usePayments() - Payment history
- useSubscription() - Subscription details
- useSavedSearches() - Saved search queries
- useValuation(propertyId) - AI valuation
```
**Query Key Structure:**
```typescript
listingsKeys = {
all: ['listings'],
search: (params) => ['listings', 'search', params],
detail: (id) => ['listings', 'detail', id]
}
```
**Provider:** `QueryProvider` wraps app with React Query client
---
## 5. AUTHENTICATION SYSTEM
### Authentication Flow
**1. Cookie-Based Session**
- Auth cookie: `goodgo_authenticated=1`
- Checked in middleware for route protection
- Checked in auth-store on app initialization
**2. Multi-Factor Support**
- 🟢 Phone + Password (native)
- 🟢 Google OAuth
- 🟢 Zalo OAuth
**3. Token Management**
- Automatic refresh on 401 responses
- Tokens stored in HTTP-only cookies (secure)
- CSRF protection enabled
**4. Protected Routes (Middleware)**
```typescript
Public: /, /login, /register, /search, /auth/callback/*
Auth-only: /login, /register (redirects to /dashboard if authenticated)
Protected: /dashboard/*, /admin/* (requires auth cookie)
```
**5. OAuth Callbacks**
- `GET /auth/callback/google?code=...&state=...`
- `GET /auth/callback/zalo?code=...`
- Exchange code for tokens via `authApi.exchangeToken()`
**Security Measures:**
- ✅ XSRF-Token header injection (auto-detected from cookies)
- ✅ Credentials: 'include' for cross-origin requests
- ✅ HTTP-only cookies (if backend supports)
- ✅ Strict SameSite policy (if configured)
---
## 6. UI/UX QUALITY
### Accessibility Features
**Semantic HTML:**
- ✅ Proper heading hierarchy (h1 → h6)
-`<section>` with aria-labelledby
- ✅ Form labels properly associated
-`<main>` with id="main-content"
**ARIA Attributes:**
- ✅ aria-label on inputs, buttons
- ✅ aria-hidden on decorative icons
- ✅ role="search" on filter bars
- ✅ role="status" for loading states
- ✅ role="alert" for error messages
- ✅ aria-labelledby linking sections
**Keyboard Navigation:**
- ✅ Focus visible on all interactive elements
- ✅ Focus ring styling (ring-2 ring-ring)
- ✅ Skip to main content link (fixed position, -translate-y-16 hidden)
- ✅ Tab order follows document flow
**Example from Landing Page:**
```tsx
<a
href="#main-content"
className="fixed left-2 top-2 z-[100] -translate-y-16 rounded-md
bg-primary px-4 py-2 text-sm font-medium text-primary-foreground
shadow-lg transition-transform focus:translate-y-0"
>
{t('skipToContent')}
</a>
```
### Responsive Design
**Mobile-First Approach:**
- Base styles for mobile
- Breakpoint utilities: sm, md, lg, xl, 2xl
- Flexbox and Grid layouts
- Aspect ratios for images
**Examples:**
```tsx
// Landing page
className="text-4xl font-bold md:text-5xl lg:text-6xl"
// Search filters
className={isSidebar ? 'w-full' : 'w-full sm:w-40'}
// Comparison table
<div className="overflow-x-auto md:overflow-x-visible">
```
**Tested Breakpoints:**
- Mobile: 320px - 640px (sm)
- Tablet: 640px - 1024px (md/lg)
- Desktop: 1024px+ (xl/2xl)
### Dark Mode Support
- ✅ Theme provider using React Context
- ✅ Respects system preference (prefers-color-scheme)
- ✅ localStorage persistence
- ✅ Class-based dark mode (document.documentElement.classList)
- ✅ Tailwind dark: prefix support
### Form Validation
- ✅ Zod schemas with i18n error messages
- ✅ React Hook Form integration
- ✅ Multi-step form with validation state
- ✅ Image upload validation
- ✅ Real-time field validation
---
## 7. MISSING PAGES & FEATURES
### Already Implemented (No Gaps)
✅ Dashboard/Analytics - COMPLETE
✅ Admin Dashboard - COMPLETE
✅ Search/Listings - COMPLETE
✅ Comparison Tool - COMPLETE
✅ User Profiles - COMPLETE
✅ Authentication - COMPLETE
### Potentially Future Enhancements
- [ ] Agent marketplace page (mentioned in app, not a critical page)
- [ ] Notifications center (backend integration ready)
- [ ] Message inbox (backend integration ready)
- [ ] Real estate agency profiles (possible B2B feature)
**Assessment:** The blueprint features are **100% implemented**. No missing critical pages.
---
## 8. PERFORMANCE OPTIMIZATION
### Client vs Server Rendering Strategy
**Server-Rendered Pages:**
- Auth callbacks (minimal interactivity)
- Some API routes
**Client-Rendered Pages (use client):**
- Landing page - requires interactive search form
- Search page - requires filter state + map view
- Dashboard pages - require interactive charts + real-time data
- Admin pages - require dynamic data updates
- Comparison - requires client-side stats calculation
**Rationale:** Client rendering used where interactivity is essential. This is appropriate for a real estate platform.
### Image Optimization
**Next.js Image Configuration:**
```typescript
images: {
remotePatterns: [{
protocol: 'https',
hostname: '**',
}],
}
```
**Usage in App:**
-`Image` component used in dashboard listings
- ✅ Property media URLs properly formatted
- ✅ Fallback placeholders for missing images
- ✅ Aspect ratio preservation
**Optimization Opportunity:**
⚠️ **Minor:** Consider adding `fill` prop with `sizes` attribute for responsive images:
```typescript
// Current
<Image src={url} width={300} height={200} alt="property" />
// Better for responsive
<Image
src={url}
fill
sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
alt="property"
/>
```
### Code Splitting
**Dynamic Imports:**
- ✅ ListingMap component (SSR: false)
- ✅ Charts (lazy loaded in dashboard)
- ✅ Heavy components deferred to client
```typescript
const ListingMap = dynamic(
() => import('@/components/map/listing-map'),
{ ssr: false, loading: () => <LoadingSpinner /> }
);
```
### Performance Monitoring
**Web Vitals:**
-`web-vitals` package (v5.2.0)
- ✅ WebVitals provider component tracks metrics
- ✅ Sentry integration for error reporting
**Metrics Tracked:**
- CLS (Cumulative Layout Shift)
- FID (First Input Delay)
- LCP (Largest Contentful Paint)
- FCP (First Contentful Paint)
- TTFB (Time to First Byte)
### Caching Strategy
**HTTP Caching Headers:** Set in next.config.js
```
Cache-Control configured via server
```
**React Query Caching:**
- Default staleTime: 0 (immediate revalidation)
- Proper invalidation on mutations

## 10. INTERNATIONALIZATION (i18n)
### Configuration
**Supported Locales:**
- ✅ Vietnamese (`vi`)
- ✅ English (`en`)
**Setup:**
- next-intl v4.9.0 with Next.js 15
- Route prefix: `as-needed` (only for non-default locale)
**Translation Files:**
- `messages/vi.json` - 10,154 bytes (comprehensive Vietnamese)
- `messages/en.json` - 8,698 bytes (comprehensive English)
**Usage Pattern:**
```typescript
const t = useTranslations('search');
// or
const t = useTranslations(); // entire namespace
```
**Translation Keys Present:**
- Common UI labels
- Form validation messages
- Error messages
- Listing types (propertyTypes.APARTMENT, etc.)
- Transaction types (transactionTypes.SALE, etc.)
- Price ranges (priceRanges.under1b, etc.)
- Admin labels
- Landing page content
**Middleware Integration:**
```typescript
export const middleware = (request: NextRequest) => {
const intlMiddleware = createIntlMiddleware(routing);
return intlMiddleware(request);
}
```
---
## 11. SECURITY ANALYSIS
### Headers & CSP
**Security Headers:**
```
X-Content-Type-Options: nosniff // Prevent MIME sniffing
X-Frame-Options: DENY // No iframe embedding
X-XSS-Protection: 1; mode=block // Legacy XSS protection
Referrer-Policy: strict-origin-when-cross-origin
Strict-Transport-Security: max-age=31536000 (1 year) + preload
Permissions-Policy:
- camera: disabled
- microphone: disabled
- geolocation: self only
- payment: self only
```
**Content Security Policy:**
```
default-src: 'self'
script-src: 'self' 'unsafe-inline' 'unsafe-eval' https://api.mapbox.com
style-src: 'self' 'unsafe-inline' https://api.mapbox.com
img-src: 'self' data: blob: https://*.mapbox.com https://*.tiles.mapbox.com https:
font-src: 'self' data:
connect-src: 'self' https://*.mapbox.com https://api.mapbox.com https://events.mapbox.com
worker-src: 'self' blob:
child-src: 'self' blob:
frame-ancestors: 'none'
base-uri: 'self'
form-action: 'self'
```
**Issues Found:**
⚠️ **UNSAFE-INLINE & UNSAFE-EVAL in CSP**
- Currently allows inline scripts for Next.js development
- **Recommendation:** In production, use `NEXT_STRICT_CSP_POLICY` env var
- Configuration exists but needs to be enabled
### CSRF Protection
**Implemented:**
```typescript
function getCsrfToken(): string | undefined {
if (typeof document === 'undefined') return undefined;
const match = document.cookie.match(/(?:^|;\s*)XSRF-TOKEN=([^;]*)/);
return match?.[1] ? decodeURIComponent(match[1]) : undefined;
}
// Auto-injected for non-safe methods
csrfHeaders['X-CSRF-Token'] = csrfToken;
```
**Safe Methods:** GET, HEAD, OPTIONS (no token needed)
### Authentication Security
**Secure Practices:**
- Credentials: 'include' ensures cookies sent
- HTTP-only cookie recommendation in middleware
- Token refresh on 401
- Automatic logout on persistent auth failures
⚠️ **Backend Dependency:**
- Frontend assumes backend sets HTTP-only cookies
- Verify backend is properly configured

? 'strict'
: 'relaxed'
```
#### 3. **Date Formatting Library** (Optional)
**Severity:** Very Low
**Impact:** Consistency in date display
```bash
npm install date-fns
# Use consistently across app instead of native Date methods
```
#### 4. **API Error Handling Consistency**
**Severity:** Very Low
**Impact:** Better UX on API failures
```typescript
// Consider adding retry logic for network errors in useQuery
const { data } = useQuery({
queryKey: ['listings'],
queryFn: listingsApi.search,
retry: 3,
retryDelay: (attemptIndex) => Math.min(1000 * 2 ** attemptIndex, 30000),
})
```
#### 5. **Logging Strategy** (Optional)
**Severity:** Very Low
**Impact:** Better debugging in production
```typescript
// Consider adding debug logs or structured logging
import pino from 'pino' // or winston
```
