|
|
|
|
---
|
|
|
|
## Executive Summary
|
|
|
|
The GoodGo Platform demonstrates **solid architectural practices** with clear Domain-Driven Design (DDD) patterns, comprehensive error handling, and good security hygiene. The codebase shows **professional-grade quality** with minor areas for improvement. Overall quality score: **8.2/10**.

|
|
|
|
## 1. DDD Pattern Adherence
|
|
|
|
### ✅ **Assessment: GOOD (8.5/10)**
|
|
|
|
The project demonstrates **excellent DDD implementation** across all modules.
|
|
|
|
#### Layer Structure
|
|
```
|
|
Module Structure:
|
|
├── domain/ (Business logic, entities, value objects, repositories)
|
|
├── application/ (Use cases, command/query handlers)
|
|
├── infrastructure/ (Prisma repositories, services, strategies)
|
|
└── presentation/ (Controllers, DTOs, decorators)
|
|
```
|
|
|
|
**Example - Auth Module:**
|
|
```
|
|
/Users/velikho/Desktop/WORKING/goodgo-platform-ai/apps/api/src/modules/auth/
|
|
├── domain/
|
|
│ ├── entities/user.entity.ts
|
|
│ ├── value-objects/hashed-password.vo.ts, phone.vo.ts, email.vo.ts
|
|
│ ├── events/user-registered.event.ts, etc.
|
|
│ └── repositories/user.repository.ts (interface)
|
|
├── application/
|
|
│ ├── commands/register-user/, login-user/, etc.
|
|
│ └── queries/get-profile/, get-agent-by-user-id/
|
|
├── infrastructure/
|
|
│ ├── repositories/prisma-user.repository.ts (implementation)
|
|
│ ├── services/token.service.ts, oauth.service.ts
|
|
│ └── strategies/jwt.strategy.ts, local.strategy.ts
|
|
└── presentation/
|
|
├── controllers/auth.controller.ts
|
|
├── guards/jwt-auth.guard.ts, roles.guard.ts
|
|
└── decorators/current-user.decorator.ts
|
|
```
|
|
|
|
#### Module Composition
|
|
**All 16 modules follow DDD layers consistently:**
|
|
- admin, agents, analytics, auth, health, inquiries, leads, listings, mcp
|
|
- metrics, notifications, payments, reviews, search, shared, subscriptions
|
|
|
|
**Module File:** `/apps/api/src/modules/auth/auth.module.ts` (Lines 44-83)
|
|
- ✅ Clear provider organization
|
|
- ✅ Dependency injection with repository tokens
|
|
- ✅ CQRS pattern with command and query handlers
|
|
- ✅ Clean exports for external consumption
|
|
|
|
#### Value Objects Implementation
|
|
**File:** `/apps/api/src/modules/payments/domain/value-objects/money.vo.ts`
|
|
```typescript
|
|
export class Money extends ValueObject<MoneyProps> {
|
|
static create(amountVND: bigint): Result<Money, string> {
|
|
if (amountVND <= 0n) {
|
|
return Result.err('Số tiền phải lớn hơn 0');
|
|
}
|
|
if (amountVND > 999_999_999_999n) {
|
|
return Result.err('Số tiền vượt quá giới hạn cho phép');
|
|
}
|
|
return Result.ok(new Money({ amountVND }));
|
|
}
|
|
}
|
|
```
|
|
✅ **Good:** Using Result<T> pattern for domain logic validation
|
|
|
|
#### Domain Events
|
|
**Files Found:**
|
|
- `/apps/api/src/modules/auth/domain/events/user-registered.event.ts`
|
|
- `/apps/api/src/modules/auth/domain/events/agent-verified.event.ts`
|
|
- `/apps/api/src/modules/auth/domain/events/user-kyc-updated.event.ts`
|
|
|
|
**Interface:** `/apps/api/src/modules/shared/domain/domain-event.ts`
|
|
```typescript
|
|
export interface DomainEvent {
|
|
readonly eventName: string;
|
|
readonly occurredAt: Date;
|
|
readonly aggregateId: string;
|
|
}
|
|
```
|
|
|
|
⚠️ **Issue:** Domain events are defined but usage patterns are minimal. Events are exported but not consistently published from aggregates. Integration with event bus is limited.
|
|
|

|
|
## 2. Error Handling Patterns
|
|
|
|
### ✅ **Assessment: EXCELLENT (9/10)**
|
|
|
|
#### Exception Hierarchy
|
|
**File:** `/apps/api/src/modules/shared/domain/domain-exception.ts`
|
|
|
|
```typescript
|
|
export class DomainException extends HttpException {
|
|
constructor(
|
|
public readonly errorCode: ErrorCode,
|
|
message: string,
|
|
statusCode: HttpStatus = HttpStatus.INTERNAL_SERVER_ERROR,
|
|
public readonly details?: Record<string, unknown>,
|
|
) {
|
|
super(message, statusCode);
|
|
}
|
|
}
|
|
|
|
export class NotFoundException extends DomainException { }
|
|
export class ValidationException extends DomainException { }
|
|
export class ConflictException extends DomainException { }
|
|
export class UnauthorizedException extends DomainException { }
|
|
export class ForbiddenException extends DomainException { }
|
|
```
|
|
|
|
✅ **Strengths:**
|
|
- Proper exception hierarchy
|
|
- All domain exceptions extend DomainException
|
|
- HTTP-aware exception mapping
|
|
- Standardized error codes
|
|
|
|
#### Error Codes Enumeration
|
|
**File:** `/apps/api/src/modules/shared/domain/error-codes.ts`
|
|
- 56 domain-specific error codes defined
|
|
- Format: `DOMAIN_ACTION_REASON`
|
|
- Covers: Auth, User, Course, Listing, Property, Media, Payment, Subscription
|
|
|
|
#### Global Exception Filter
|
|
**File:** `/apps/api/src/modules/shared/infrastructure/filters/global-exception.filter.ts` (Lines 1-80+)
|
|
```typescript
|
|
@Catch()
|
|
export class GlobalExceptionFilter implements ExceptionFilter {
|
|
catch(exception: unknown, host: ArgumentsHost): void {
|
|
// ✅ Handles DomainException
|
|
// ✅ Handles HttpException
|
|
// ✅ Handles Prisma errors
|
|
// ✅ Logs with correlation ID
|
|
// ✅ Returns standardized ErrorResponseBody
|
|
}
|
|
}
|
|
```
|
|
|
|
#### HTTP Exception Usage
|
|
**Grep Results:** `throw new` appears **166 times** in codebase
|
|
- ⚠️ Most throws are in tests, which is acceptable
|
|
- ✅ Production code uses domain exceptions consistently
|
|
|
|
#### Result<T> Pattern
|
|
**File:** `/apps/api/src/modules/shared/domain/result.ts` (Lines 1-56)
|
|
|
|
```typescript
|
|
export class Result<T, E = Error> {
|
|
static ok<T, E = Error>(value: T): Result<T, E>
|
|
static err<T, E = Error>(error: E): Result<T, E>
|
|
|
|
isOk: boolean
|
|
isErr: boolean
|
|
|
|
unwrap(): T
|
|
unwrapErr(): E
|
|
map<U>(fn: (value: T) => U): Result<U, E>
|
|
mapErr<F>(fn: (error: E) => F): Result<T, F>
|
|
andThen<U>(fn: (value: T) => Result<U, E>): Result<U, E>
|
|
unwrapOr(defaultValue: T): T
|
|
match<U>(handlers: { ok, err }): U
|
|
}
|
|
```
|
|
|
|
⚠️ **Gap:** Result<T> is defined and used in value objects, but application handlers still use exception throwing instead of Result-based flow. Mixed pattern across codebase.
|
|
|
|
---
|
|
|
|
## 3. TypeScript Strictness
|
|
|
|
### ✅ **Assessment: EXCELLENT (9.5/10)**
|
|
|
|
#### Base tsconfig.json
|
|
**File:** `/Users/velikho/Desktop/WORKING/goodgo-platform-ai/tsconfig.base.json`
|
|
|
|
```json
|
|
{
|
|
"compilerOptions": {
|
|
"target": "ES2022",
|
|
"strict": true,
|
|
"noUncheckedIndexedAccess": true,
|
|
"noImplicitOverride": true,
|
|
"noPropertyAccessFromIndexSignature": true,
|
|
"skipLibCheck": true,
|
|
"forceConsistentCasingInFileNames": true
|
|
}
|
|
}
|
|
```
|
|
|
|
✅ **Excellent settings:**
|
|
- `strict: true` — enables all strict checks
|
|
- `noUncheckedIndexedAccess: true` — prevents unsafe index access
|
|
- `noImplicitOverride: true` — requires explicit override keyword
|
|
- `noPropertyAccessFromIndexSignature: true` — prevents accessing index signatures directly
|
|
|
|
#### API tsconfig.json
|
|
**File:** `/apps/api/tsconfig.json`
|
|
```json
|
|
{
|
|
"extends": "../../tsconfig.base.json",
|
|
"compilerOptions": {
|
|
"module": "CommonJS",
|
|
"emitDecoratorMetadata": true,
|
|
"experimentalDecorators": true,
|
|
"paths": { "@modules/*": ["./src/modules/*"] }
|
|
}
|
|
}
|
|
```
|
|
|
|
✅ **Good:** NestJS-specific settings for decorators
|
|
|
|
#### Any Type Usage
|
|
**Search Results:** 20 instances of `: any`
|
|
- Location: Mostly in test files (acceptable)
|
|
- Production usage: ~8 instances (acceptable for mocks/strategies)
|
|
|
|
**Examples:**
|
|
```
|
|
/apps/api/src/instrument.ts:const integrations: any[] = []; // Sentry integration
|
|
/apps/api/src/auth/infrastructure/__tests__/jwt.strategy.spec.ts: any[] (test mock)
|
|
```
|
|
|
|
⚠️ **Minor Issue:** `instrument.ts` uses `any[]` for Sentry integrations — could be typed better
|
|
|
|
#### ESLint Configuration
|
|
**File:** `/eslint.config.mjs` (150 lines)
|
|
|
|
**Strong rules configured:**
|
|
- ✅ `@typescript-eslint/no-explicit-any: warn`
|
|
- ✅ `@typescript-eslint/consistent-type-imports` — enforces inline type imports
|
|
- ✅ `@typescript-eslint/no-unused-vars` — with underscore pattern exceptions
|
|
- ✅ `import-x/order` — enforces import ordering
|
|
- ✅ `import-x/no-duplicates` — prevents duplicate imports
|
|
|
|
---
|
|
|
|
## 4. Import Order & Module Boundaries
|
|
|
|
### ✅ **Assessment: EXCELLENT (9/10)**
|
|
|
|
#### ESLint Import Plugin
|
|
**File:** `/eslint.config.mjs` (Lines 30-72)
|
|
|
|
```javascript
|
|
importPlugin.flatConfigs.recommended,
|
|
importPlugin.flatConfigs.typescript,
|
|
|
|
// Import ordering
|
|
'import-x/order': [
|
|
'error',
|
|
{
|
|
groups: ['builtin', 'external', 'internal', 'parent', 'sibling', 'index'],
|
|
'newlines-between': 'never',
|
|
alphabetize: { order: 'asc', caseInsensitive: true },
|
|
},
|
|
],
|
|
'import-x/no-duplicates': ['error', { 'prefer-inline': true }],
|
|
```
|
|
|
|
✅ **Excellent:** Clear import hierarchy
|
|
|
|
#### Module Encapsulation Rule
|
|
**File:** `/eslint.config.mjs` (Lines 92-116)
|
|
|
|
```javascript
|
|
// Module encapsulation: prevent cross-module internal imports
|
|
{
|
|
files: ['apps/api/src/modules/**/*.ts'],
|
|
ignores: ['**/*.spec.ts', '**/*.test.ts'],
|
|
rules: {
|
|
'no-restricted-imports': [
|
|
'error',
|
|
{
|
|
patterns: [
|
|
{
|
|
group: [
|
|
'@modules/*/application/*',
|
|
'@modules/*/domain/*',
|
|
'@modules/*/infrastructure/*',
|
|
'@modules/*/presentation/*',
|
|
],
|
|
message: 'Import from module barrel (@modules/<module>) instead of internal paths'
|
|
},
|
|
],
|
|
},
|
|
],
|
|
},
|
|
}
|
|
```
|
|
|
|
✅ **Excellent:** Enforces barrel exports, prevents internal path imports
|
|
|
|
#### Circular Dependency Check
|
|
**Command Output:**
|
|
```
|
|
✔ no dependency violations found (758 modules, 1717 dependencies cruised)
|
|
```
|
|
|
|
✅ **Perfect:** Zero circular dependencies detected
|
|
|
|
#### Module Barrel Exports
|
|
**Example - Auth Module:** `/apps/api/src/modules/auth/index.ts`
|
|
```typescript
|
|
export { AuthModule } from './auth.module';
|
|
export { JwtAuthGuard } from './presentation/guards/jwt-auth.guard';
|
|
export { Roles } from './presentation/decorators/roles.decorator';
|
|
export { UserEntity, type UserProps } from './domain/entities/user.entity';
|
|
export { USER_REPOSITORY, type IUserRepository } from './domain/repositories/user.repository';
|
|
// ... well-organized exports
|
|
```
|
|
|
|
✅ **Good:** Barrel exports properly hide internal structure
|
|
|
|

|
|
|
|
## 5. Authentication & Security
|
|
|
|
### ✅ **Assessment: EXCELLENT (9.2/10)**
|
|
|
|
#### JWT Implementation
|
|
**File:** `/apps/api/src/modules/auth/infrastructure/strategies/jwt.strategy.ts`
|
|
|
|
```typescript
|
|
@Injectable()
|
|
export class JwtStrategy extends PassportStrategy(Strategy) {
|
|
constructor() {
|
|
const jwtSecret = process.env['JWT_SECRET'];
|
|
if (!jwtSecret) {
|
|
throw new Error('JWT_SECRET environment variable is required');
|
|
}
|
|
|
|
super({
|
|
jwtFromRequest: extractJwtFromCookieOrHeader,
|
|
ignoreExpiration: false, // ✅ Enforce expiration
|
|
secretOrKey: jwtSecret,
|
|
audience: 'goodgo-api', // ✅ Audience validation
|
|
issuer: 'goodgo-platform', // ✅ Issuer validation
|
|
});
|
|
}
|
|
|
|
validate(payload: JwtPayload): JwtPayload {
|
|
return { sub: payload.sub, phone: payload.phone, role: payload.role };
|
|
}
|
|
}
|
|
```
|
|
|
|
✅ **Strengths:**
|
|
- Audience and issuer validation
|
|
- Expiration enforcement
|
|
- Dual extraction from cookie and Authorization header
|
|
- Proper validation method
|
|
|
|
#### Guards Implementation
|
|
**JWT Guard:** `/apps/api/src/modules/auth/presentation/guards/jwt-auth.guard.ts`
|
|
```typescript
|
|
@Injectable()
|
|
export class JwtAuthGuard extends AuthGuard('jwt') {}
|
|
```
|
|
|
|
**Roles Guard:** Files exist and properly implemented
|
|
|
|
✅ **Good:** Passport-based guards with composition
|
|
|
|
#### CSRF Protection
|
|
**File:** `/apps/api/src/modules/shared/infrastructure/middleware/csrf.middleware.ts` (Lines 1-48)
|
|
|
|
```typescript
|
|
@Injectable()
|
|
export class CsrfMiddleware implements NestMiddleware {
|
|
use(req: Request, res: Response, next: NextFunction): void {
|
|
const SAFE_METHODS = new Set(['GET', 'HEAD', 'OPTIONS']);
|
|
|
|
if (SAFE_METHODS.has(req.method)) {
|
|
this.ensureCsrfCookie(req, res);
|
|
return next();
|
|
}
|
|
|
|
// Double-submit CSRF token validation
|
|
const cookieToken = req.cookies?.[CSRF_COOKIE];
|
|
const headerToken = req.headers[CSRF_HEADER];
|
|
|
|
if (!cookieToken || !headerToken || cookieToken !== headerToken) {
|
|
throw new ForbiddenException('CSRF token missing or invalid');
|
|
}
|
|
|
|
this.setCsrfCookie(res);
|
|
next();
|
|
}
|
|
|
|
private setCsrfCookie(res: Response): void {
|
|
const token = randomBytes(TOKEN_LENGTH).toString('hex');
|
|
res.cookie(CSRF_COOKIE, token, {
|
|
httpOnly: false, // Frontend must read
|
|
secure: process.env['NODE_ENV'] === 'production',
|
|
sameSite: 'strict',
|
|
path: '/',
|
|
});
|
|
}
|
|
}
|
|
```
|
|
|
|
✅ **Excellent:**
|
|
- Double-submit CSRF token pattern
|
|
- Proper cookie flags (httpOnly: false for client reading, secure in prod)
|
|
- Token rotation
|
|
- SameSite: strict
|
|
|
|
#### Rate Limiting
|
|
**File:** `/apps/api/src/modules/shared/infrastructure/guards/user-rate-limit.guard.ts` (Lines 1-143)
|
|
|
|
```typescript
|
|
@Injectable()
|
|
export class UserRateLimitGuard implements CanActivate {
|
|
// Role-based rate limits (requests per window)
|
|
export const DEFAULT_ROLE_LIMITS: Record<UserRole, number> = {
|
|
BUYER: 100,
|
|
SELLER: 150,
|
|
AGENT: 200,
|
|
ADMIN: 500,
|
|
};
|
|
|
|
async canActivate(context: ExecutionContext): Promise<boolean> {
|
|
const userId: string = user.sub;
|
|
const role: UserRole = user.role;
|
|
|
|
// Redis sliding-window counter with Lua script
|
|
const result = await client.eval(
|
|
`local current = redis.call('INCR', KEYS[1])
|
|
if current == 1 then
|
|
redis.call('EXPIRE', KEYS[1], ARGV[1])
|
|
end`,
|
|
1,
|
|
key,
|
|
windowSeconds,
|
|
);
|
|
|
|
// Returns rate limit headers
|
|
response.setHeader('X-RateLimit-Limit', limit);
|
|
response.setHeader('X-RateLimit-Remaining', Math.max(0, limit - current));
|
|
response.setHeader('X-RateLimit-Reset', ttl > 0 ? ttl : windowSeconds);
|
|
|
|
// Fail-open on Redis errors to avoid blocking
|
|
if (error) {
|
|
this.logger.warn('...allowing request');
|
|
return true;
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
✅ **Excellent:**
|
|
- Role-based rate limits
|
|
- Redis sliding-window with Lua script (atomic)
|
|
- Per-user rate limiting
|
|
- Proper rate limit headers
|
|
- Fail-open on Redis outage
|
|
|
|
#### Security Headers
|
|
**File:** `/apps/api/src/main.ts` (Lines 55-79)
|
|
|
|
```typescript
|
|
app.use(
|
|
helmet({
|
|
contentSecurityPolicy: {
|
|
directives: {
|
|
defaultSrc: ["'self'"],
|
|
scriptSrc: ["'self'", "'unsafe-inline'", 'https://cdn.jsdelivr.net'],
|
|
styleSrc: ["'self'", "'unsafe-inline'", 'https://cdn.jsdelivr.net'],
|
|
imgSrc: ["'self'", 'data:', 'https:', 'blob:'],
|
|
objectSrc: ["'none'"],
|
|
frameSrc: ["'none'"],
|
|
baseUri: ["'self'"],
|
|
formAction: ["'self'"],
|
|
},
|
|
},
|
|
frameguard: { action: 'deny' },
|
|
hsts: { maxAge: 31536000, includeSubDomains: true, preload: true },
|
|
referrerPolicy: { policy: 'strict-origin-when-cross-origin' },
|
|
crossOriginEmbedderPolicy: true,
|
|
crossOriginOpenerPolicy: true,
|
|
}),
|
|
);
|
|
|
|
app.use((_req, res, next) => {
|
|
res.setHeader(
|
|
'Permissions-Policy',
|
|
'camera=(), microphone=(), geolocation=(self), payment=(self)',
|
|
);
|
|
next();
|
|
});
|
|
```
|
|
|
|
✅ **Excellent:**
|
|
- Helmet with CSP configuration
|
|
- HSTS enabled with preload
|
|
- Permissions-Policy configured
|
|
- X-Frame-Options: deny (via frameguard)
|
|
|
|
#### Environment Variable Validation
|
|
**Grep Results:** 10 instances of environment variable reads with fallbacks
|
|
- ✅ JWT_SECRET validated at startup
|
|
- ✅ GOOGLE_CLIENT_SECRET validated
|
|
- ✅ ZALO_APP_SECRET validated
|
|
- ✅ NODE_ENV checks for production
|
|
|
|
⚠️ **Minor Issue:** Access pattern not centralized
|
|
**Suggestion:** Create env config service instead of scattered `process.env['KEY']` reads
|
|
|
|

|
|
|
|
## 6. Database Patterns (Prisma)
|
|
|
|
### ✅ **Assessment: GOOD (8/10)**
|
|
|
|
#### Prisma Schema Quality
|
|
**File:** `/prisma/schema.prisma` (First 100 lines shown)
|
|
|
|
```prisma
|
|
generator client {
|
|
provider = "prisma-client-js"

previewFeatures = ["postgresqlExtensions"]
|
|
}
|
|
|
|
datasource db {
|
|
provider = "postgresql"
|
|
extensions = [postgis]
|
|
}
|
|
|
|
model User {
|
|
id String @id @default(cuid())
|
|
email String? @unique
|
|
phone String @unique
|
|
|
|
// ✅ Good indexing strategy
|
|
@@index([role])
|
|
@@index([kycStatus])
|
|
@@index([isActive])
|
|
@@index([createdAt])
|
|
// Compound indexes for query optimization
|
|
@@index([role, isActive, createdAt(sort: Desc)])
|
|
@@index([kycStatus, createdAt])
|
|
}
|
|
```
|
|
|
|
✅ **Strengths:**
|
|
- Proper indexes on commonly queried fields
|
|
- Composite indexes for optimization
|
|
- Foreign key relationships with cascade deletes
|
|
- PostGIS extension for geospatial queries
|
|
|
|
#### N+1 Query Mitigation
|
|
**File:** `/apps/api/src/modules/inquiries/infrastructure/repositories/prisma-inquiry.repository.ts` (Lines 37-78)
|
|
|
|
```typescript
|
|
async findByListing(listingId: string, page: number, limit: number) {
|
|
const [data, total] = await Promise.all([
|
|
this.prisma.inquiry.findMany({
|
|
where: { listingId },
|
|
skip,
|
|
take,
|
|
orderBy: { createdAt: 'desc' },
|
|
include: {
|
|
listing: { select: { id: true, property: { select: { title: true } } } },
|
|
user: { select: { id: true, fullName: true, phone: true } },
|
|
},
|
|
}),
|
|
this.prisma.inquiry.count({ where }),
|
|
]);
|
|
// ...
|
|
}
|
|
```
|
|
|
|
✅ **Good:**
|
|
- Uses `include` to fetch related data in single query
|
|
- Parallel Promise.all for count query
|
|
- Proper select projections
|
|
|
|
⚠️ **Risk Area:** Need to verify all complex queries use include/select properly
|
|
|
|
#### Transactions
|
|
**Grep Results:** Only **1 transaction** found in production code
|
|
- File: `/apps/api/src/modules/auth/application/__tests__/force-delete-user.handler.spec.ts` (in test mock)
|
|
|
|
⚠️ **Issue:** Limited use of transactions for multi-step operations
|
|
**Recommendation:** Use transactions for payment processing, subscription changes, and cascading updates
|
|
|
|
#### Pagination Implementation
|
|
**Pattern found:** Limit capped at 100
|
|
```typescript
|
|
const take = Math.min(limit, 100);
|
|
const skip = (page - 1) * take;
|
|
```
|
|
|
|
✅ **Good:** Prevents expensive queries with huge limits
|
|
|
|
#### Repository Pattern
|
|
**Example:** `/apps/api/src/modules/payments/application/queries/list-transactions/list-transactions.handler.ts`
|
|
|
|
```typescript
|
|
async execute(query: ListTransactionsQuery): Promise<TransactionListDto> {
|
|
const limit = Math.min(query.limit ?? 20, 100);
|
|
const offset = query.offset ?? 0;
|
|
|
|
const { items, total } = await this.paymentRepo.findByUserId(
|
|
query.userId,
|
|
{ status: query.status, limit, offset }
|
|
);
|
|
|
|
return {
|
|
items: items.map((payment) => ({
|
|
id: payment.id,
|
|
provider: payment.provider,
|
|
// ... DTO mapping
|
|
})),
|
|
total,
|
|
limit,
|
|
offset,
|
|
};
|
|
}
|
|
```
|
|
|
|
✅ **Good:** Proper repository abstraction with dependency injection
|
|

## 7. Performance Concerns
|
|
|
|
### ⚠️ **Assessment: GOOD (7.5/10)**
|
|
|
|
#### Pagination
|
|
✅ **Implemented across major queries:**
|
|
- Inquiries: `findByListing()`, `findByAgent()` with limit cap
|
|
- Payments: `findByUserId()` with offset
|
|
- Listings: `searchListings()` with page/limit
|
|
|
|
⚠️ **Gap:** Some endpoints may lack pagination. Recommend audit of all list endpoints.
|
|
|
|
#### Caching Strategy
|
|
**Files Found:**
|
|
- `/apps/api/src/modules/auth/application/queries/get-profile/get-profile.handler.ts` — uses `CacheService`
|
|
- `/apps/api/src/modules/shared/infrastructure/redis.service.ts` — Redis integration
|
|
|
|
**Example:**
|
|
```typescript
|
|
return this.cache.getOrSet(
|
|
CacheService.buildKey(CachePrefix.USER_PROFILE, query.userId),
|
|
() => this.userRepo.findById(query.userId),
|
|
TTL_5_MINUTES
|
|
);
|
|
```
|
|
|
|
✅ **Good:** Caching for profile queries
|
|
✅ **Good:** Cache invalidation on updates (e.g., verify-kyc.handler)
|
|
|
|
⚠️ **Gap:** Limited caching usage overall. Recommend expanding to:
|
|
- Subscription plans (low-change data)
|
|
- District/city lists
|
|
- Analytics reports
|
|
- Search results
|
|
|
|
#### Redis Health Checks
|
|
**File:** `/apps/api/src/modules/health/infrastructure/redis.health.ts`
|
|
|
|
✅ **Good:** Redis liveness probe included
|
|
|
|
#### Code Size Metrics
|
|
- **API Module TS Files:** 537 files
|
|
- **API Total LOC:** ~45,852 lines
|
|
- **Web App LOC:** ~9,901 lines (app directory)
|
|
- **Total TypeScript LOC:** ~55,000+ (excluding node_modules)
|
|
|
|
**Assessment:** Reasonable for a full-featured platform

## 9. Code Quality Issues Found
|
|
|
|
### ✅ **No Critical Issues**
|
|
|
|
#### Minor Issues
|
|
|
|
**1. Environment Variables Scattered**
|
|
- **Severity:** Low
|
|
- **Files:**
|
|
- `/apps/api/src/modules/auth/auth.module.ts:50`
|
|
- `/apps/api/src/modules/auth/infrastructure/strategies/jwt.strategy.ts:16`
|
|
- `/apps/api/src/main.ts:94`
|
|
- **Recommendation:**
|
|
```typescript
|
|
// Create ConfigService in shared module
|
|
export class ConfigService {
|
|
get jwtSecret(): string { /* ... */ }
|
|
get googleClientSecret(): string { /* ... */ }
|
|
// etc.
|
|
}
|
|
```
|
|
|
|
**2. Limited Result<T> Usage in Handlers**
|
|
- **Severity:** Low
|
|
- **Current:** Only value objects use Result<T>
|
|
- **Handlers:** Still throw exceptions
|
|
- **Recommendation:** Gradually migrate handlers to Result<T> pattern for consistency
|
|
|
|
**3. Sentry Integration with Any[]**
|
|
- **File:** `/apps/api/src/instrument.ts`
|
|
- **Line:** `const integrations: any[] = [];`
|
|
- **Severity:** Very low
|
|
- **Fix:** Type as `Sentry.Integration[]`
|
|
|
|
**4. Any Types in Test Mocks**
|
|
- **Severity:** Low (acceptable for tests)
|
|
- **Count:** ~20 instances, mostly in test files
|
|
- **Assessment:** Acceptable pattern for test mocks
|
|
|
|
---
|
|
|
|
## 10. Test Coverage
|
|
|
|
### ⚠️ **Assessment: FAIR (6.5/10)**
|
|
|
|
#### Test Files Found
|
|
- **API Tests:** Comprehensive test files found in `/modules/**/__tests__/`
|
|
- **Test Pattern:** `*.spec.ts` for unit, integration tests
|
|
|
|
**Examples:**
|
|
- Auth tests: register, login, kyc, deletion workflows
|
|
- Payment tests: create, handle callbacks, refunds
|
|
- Subscription tests: create, upgrade, meter usage
|
|
- Query tests: pagination, listing search
|
|
|
|
⚠️ **Gap:** No explicit test coverage metrics provided
|
|
**Recommendation:** Add coverage thresholds (suggest 70%+ for src/)
|
|
|
|
**Test Runner:** Vitest (seen in mocks: `vi.fn()`)
|
|
