chore(docs): consolidate 22 audit files from root into docs/audits/

Root directory had accumulated audit/exploration markdown files cluttering
the project root. Moved all audit-related files to docs/audits/ with a
README.md index, and updated cross-references in K6_LOAD_TESTING_GUIDE.md
and README_FRONTEND_DOCS.md.

## 🔴 CRITICAL ISSUES (Must Fix)
### 1. Dialog Component Missing Accessibility
**File:** `apps/web/components/ui/dialog.tsx`
**Issues:**
- Missing `role="dialog"`
- Missing `aria-modal="true"`
- No focus trap
- No escape key handling
- Background not hidden from screen readers
**Time to Fix:** 2-3 hours | **Priority:** 1
**Quick Fix Checklist:**
- [ ] Add role="dialog" to dialog container
- [ ] Add aria-modal="true"
- [ ] Implement escape key listener
- [ ] Add aria-hidden="true" to backdrop
- [ ] Test with NVDA screen reader
---
### 2. Image Gallery Thumbnail Buttons Missing Labels
**File:** `apps/web/components/listings/image-gallery.tsx:69-84`
**Issue:** Thumbnail buttons lack aria-labels
**Time to Fix:** 15-30 minutes | **Priority:** 2
**Quick Fix:**
```tsx
// Add this to each thumbnail button:
aria-label={`Select image ${index + 1}${img.caption ? ': ' + img.caption : ''}`}
aria-pressed={index === selectedIndex}
```
---
## 🟡 MAJOR ISSUES (Should Fix)
### 1. Admin Layout Header Missing Banner Role
**File:** `apps/web/app/[locale]/(admin)/layout.tsx:134`
**Quick Fix:**
```tsx
// Change from:
<header className="sticky...">
// To:
<header role="banner" className="sticky...">
```
**Time to Fix:** 2 minutes | **Priority:** 3
---
### 2. Color Contrast Not Verified
**Issue:** CSS variables defined but contrast ratios not tested
**Impact:** Potential WCAG 1.4.3 violation
**Time to Fix:** 4-6 hours testing
**Testing Checklist:**
- [ ] Extract CSS variable values from globals.css
- [ ] Test with WebAIM Contrast Checker
- [ ] Verify 4.5:1 for normal text (WCAG AA)
- [ ] Verify 7:1 for AAA compliance
- [ ] Test in both light and dark modes
---
### 3. Landing Page Search Input Missing Visible Label
**File:** `apps/web/app/[locale]/(public)/page.tsx:87-92`
**Quick Fix:**
```tsx
<div className="flex flex-col gap-1">
<label htmlFor="search-input" className="sr-only">
{t('landing.searchPlaceholder')}
</label>
<Input
id="search-input"
placeholder={t('landing.searchPlaceholder')}
value={searchQuery}
onChange={(e) => setSearchQuery(e.target.value)}
/>
</div>
```
**Time to Fix:** 30 minutes | **Priority:** 4
---
## 🟢 MINOR ISSUES (Nice to Have)
### 1. Redundant aria-labels on Visible Text
**File:** `apps/web/app/[locale]/(dashboard)/layout.tsx:125`
**Issue:** Links have aria-label when text is already visible
**Recommendation:** Remove redundant aria-labels - visible text is better for accessibility
---
## ✅ WHAT'S WORKING WELL
### Authentication Forms
- ✅ All inputs have visible labels with `<Label htmlFor="id">`
- ✅ Error messages linked via `aria-describedby`
- ✅ Invalid state marked with `aria-invalid`
- ✅ Password toggle has proper `aria-label`
- **Example:** `apps/web/app/[locale]/(auth)/login/page.tsx`
### Skip-to-Content Link
- ✅ Properly implemented with focus visibility
- ✅ Hidden by default, visible on focus
- ✅ Links to `id="main-content"`
- **Example:** `apps/web/app/[locale]/layout.tsx:105-110`
### Navigation
- ✅ All navs have `aria-label`
- ✅ Mobile menu toggles have dynamic labels
- ✅ Icons properly hidden with `aria-hidden="true"`
- **Examples:** All layout files
### Search & Filters
- ✅ Filter section has `role="search"`
- ✅ All selects have `aria-label`
- ✅ Range inputs properly labeled
- **Example:** `apps/web/components/search/filter-bar.tsx`
### Image Gallery
- ✅ Previous/Next buttons have aria-labels
- ✅ Good semantic structure
- **Example:** `apps/web/components/listings/image-gallery.tsx:47, 54`

## 🔍 Code Examples
### Good ARIA Usage Example
```tsx
// Good: Dynamic aria-label that updates based on state
<button
aria-label={mobileMenuOpen ? t('nav.closeMenu') : t('nav.openMenu')}
onClick={() => setMobileMenuOpen(!mobileMenuOpen)}
>
{mobileMenuOpen ? <X /> : <Menu />}
</button>
```
### Form Accessibility Example
```tsx
// Good: Proper label association + error handling
<div className="space-y-2">
<Label htmlFor="phone">{t('phone')}</Label>
<Input
id="phone"
type="tel"
aria-describedby={errors.phone ? 'phone-error' : undefined}
aria-invalid={!!errors.phone}
{...register('phone')}
/>
{errors.phone && (
<p id="phone-error" role="alert">{errors.phone.message}</p>
)}
</div>
```
### Search Form Example
```tsx
// Good: Proper semantic role with labeled controls
<form role="search" aria-label={t('filters')}>
<Select aria-label={t('allTransactions')}>
{/* options */}
</Select>
</form>
```

# Accessibility Code Fixes - Detailed Implementation Guide
## Fix #1: File Upload Input aria-label
**File**: `apps/web/components/listings/image-upload.tsx`
**Line**: 118
### Before
```tsx
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
onChange={(e) => {
if (e.target.files) addFiles(e.target.files);
e.target.value = '';
}}
/>
```
### After
```tsx
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
aria-label="Chọn ảnh để tải lên"
onChange={(e) => {
if (e.target.files) addFiles(e.target.files);
e.target.value = '';
}}
/>
```
**Why**: Hidden inputs need aria-label so screen readers can announce their purpose when focused.
---
## Fix #2: Search Dialog Input aria-label
**File**: `apps/web/app/[locale]/(public)/search/page.tsx`
**Line**: 189
### Before
```tsx
<input
type="text"
value={saveName}
onChange={(e) => setSaveName(e.target.value)}
placeholder="Tên tìm kiếm (VD: Chung cư Q7 dưới 3 tỷ)"
className="mb-3 w-full rounded-md border bg-background px-3 py-2 text-sm outline-none focus:ring-2 focus:ring-primary"
maxLength={100}
onKeyDown={(e) => e.key === 'Enter' && handleSaveSearch()}
/>
```
### After
```tsx
<input
type="text"
value={saveName}
onChange={(e) => setSaveName(e.target.value)}
placeholder="Tên tìm kiếm (VD: Chung cư Q7 dưới 3 tỷ)"
aria-label="Tên bộ lọc tìm kiếm"
className="mb-3 w-full rounded-md border bg-background px-3 py-2 text-sm outline-none focus:ring-2 focus:ring-primary"
maxLength={100}
onKeyDown={(e) => e.key === 'Enter' && handleSaveSearch()}
/>
```
**Why**: Text inputs need aria-label when no associated label element exists. Placeholder is not a substitute for aria-label.
---
## Fix #3: Admin Moderation - Select All Checkbox
**File**: `apps/web/app/[locale]/(admin)/admin/moderation/page.tsx`
**Line**: 222
### Before
```tsx
<TableHead className="w-10">
<input
type="checkbox"
checked={selected.size === result.data.length && result.data.length > 0}
onChange={toggleSelectAll}
className="rounded border-input"
/>
</TableHead>
```
### After
```tsx
<TableHead className="w-10">
<input
type="checkbox"
aria-label="Chọn tất cả tin đăng"
checked={selected.size === result.data.length && result.data.length > 0}
onChange={toggleSelectAll}
className="rounded border-input"
/>
</TableHead>
```
**Why**: Checkbox in table headers need aria-label to distinguish them from row checkboxes.
---
## Fix #4: Admin Moderation - Row Checkboxes
**File**: `apps/web/app/[locale]/(admin)/admin/moderation/page.tsx`
**Line**: 242
### Before
```tsx
<TableCell>
<input
type="checkbox"
checked={selected.has(item.listingId)}
onChange={() => toggleSelect(item.listingId)}
className="rounded border-input"
/>
</TableCell>
```
### After (Option 1 - Simple)
```tsx
<TableCell>
<input
type="checkbox"
aria-label={`Chọn tin đăng: ${item.listingId}`}
checked={selected.has(item.listingId)}
onChange={() => toggleSelect(item.listingId)}
className="rounded border-input"
/>
</TableCell>
```
### After (Option 2 - Better with title)
```tsx
<TableCell>
<input
type="checkbox"
aria-label={`Chọn tin đăng: ${item.title || item.listingId}`}
checked={selected.has(item.listingId)}
onChange={() => toggleSelect(item.listingId)}
className="rounded border-input"
/>
</TableCell>
```
**Why**: Each checkbox needs unique aria-label that includes context about what listing it represents.
---
## Fix #5: Test Mock Image Component
**File**: `apps/web/app/[locale]/(public)/search/__tests__/search.spec.tsx`
**Line**: 46
### Before
```tsx
vi.mock('next/image', () => ({
default: (props: Record<string, unknown>) => <img {...props} />,
}));
```
### After (Option 1 - Simple)
```tsx
vi.mock('next/image', () => ({
default: (props: Record<string, unknown>) => <img {...props} alt={props.alt || ''} />,
}));
```
### After (Option 2 - With Warning)
```tsx
vi.mock('next/image', () => ({
default: (props: Record<string, unknown>) => {
if (!props.alt) {
console.warn('Image mock: Missing alt attribute', props);
}
return <img {...props} alt={props.alt || 'image'} />;
},
}));
```
**Why**: Mock should enforce alt attribute to catch missing alts in tests before production.
---
## Fix #6 (Enhancement): Image Upload Drag-Drop Accessibility
**File**: `apps/web/components/listings/image-upload.tsx`
**Lines**: 86-128
### Current Code
```tsx
<div
onDragOver={handleDragOver}
onDragLeave={handleDragLeave}
onDrop={handleDrop}
onClick={() => inputRef.current?.click()}
className={cn(
'flex cursor-pointer flex-col items-center justify-center rounded-lg border-2 border-dashed p-8 transition-colors',
isDragging
? 'border-primary bg-primary/5'
: 'border-muted-foreground/25 hover:border-primary/50',
)}
>
<svg>...</svg>
<p className="text-sm font-medium">Kéo thả nh vào đây hoặc nhấp đ chọn</p>
<p className="mt-1 text-xs text-muted-foreground">
JPG, PNG, WebP - Tối đa {maxFiles} nh, mỗi nh 10MB
</p>
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
onChange={(e) => {
if (e.target.files) addFiles(e.target.files);
e.target.value = '';
}}
/>
</div>
```
### Enhanced Code
```tsx
<div
onDragOver={handleDragOver}
onDragLeave={handleDragLeave}
onDrop={handleDrop}
onClick={() => inputRef.current?.click()}
role="button"
tabIndex={0}
aria-label="Khu vực kéo thả hoặc nhấp để tải ảnh lên"
onKeyDown={(e) => {
if (e.key === 'Enter' || e.key === ' ') {
e.preventDefault();
inputRef.current?.click();
}
}}
className={cn(
'flex cursor-pointer flex-col items-center justify-center rounded-lg border-2 border-dashed p-8 transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-primary focus-visible:ring-offset-2',
isDragging
? 'border-primary bg-primary/5'
: 'border-muted-foreground/25 hover:border-primary/50',
)}
>
<svg>...</svg>
<p className="text-sm font-medium">Kéo thả nh vào đây hoặc nhấp đ chọn</p>
<p className="mt-1 text-xs text-muted-foreground">
JPG, PNG, WebP - Tối đa {maxFiles} nh, mỗi nh 10MB
</p>
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
aria-label="Chọn ảnh để tải lên"
onChange={(e) => {
if (e.target.files) addFiles(e.target.files);
e.target.value = '';
}}
/>
</div>
```
**Changes**:
- `role="button"` - Identifies div as an interactive button
- `tabIndex={0}` - Makes div keyboard accessible
- `aria-label` - Describes the purpose to screen readers
- `onKeyDown` handler - Allows Enter/Space to activate
- `focus-visible` styles - Shows focus indicator for keyboard navigation
**Why**: Makes drag-drop area fully keyboard accessible for users who can't use a mouse.
---
## Testing After Implementation
### 1. Screen Reader Testing
```bash
# Use VoiceOver (Mac), NVDA (Windows), or JAWS
# Navigate to each fixed element and verify:
# - Input is announced with its aria-label
# - Checkbox is announced with its aria-label
# - Purpose is clear from screen reader announcement
```
### 2. Keyboard Navigation Testing
```bash
# Tab through the page
# Verify:
# - All interactive elements are reachable via Tab
# - Focus is visible on all elements
# - Enter/Space activates buttons and checkboxes
# - Image upload drag area is focused and can be activated with keyboard
```
### 3. Automated Testing
```bash
# Run axe
npm run test:a11y
# Or use Lighthouse
npx lighthouse https://localhost:3000 --view
# ESLint JSX Accessibility Plugin should catch these issues:
npm run lint
```
### 4. Visual Testing
```bash
# Verify with browser dev tools:
# - Inspect each input to confirm aria-label attribute exists
# - Check for proper focus styles
# - Verify focus ring colors meet contrast requirements
```

✅ All Form Controls: Have labels or aria-labels
✅ Cards: Have article labels (property cards)
🔴 NEEDING ATTENTION:
❌ CRITICAL: Image Gallery Thumbnail Buttons
File: apps/web/components/listings/image-gallery.tsx:69-84
Issue: No aria-label on thumbnail selection buttons
Impact: Screen readers say "button" with no context
Fix: Add aria-label={`Select image ${index + 1}`}
⚠️ MINOR: Navigation Links (redundant labels)
File: apps/web/app/[locale]/(dashboard)/layout.tsx:125
Issue: aria-label on links when text is visible
Recommendation: Remove aria-label (visible text is better)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
6⃣ LAYOUT STRUCTURE & LANDMARK REGIONS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Landmark Distribution:
HEADERS (3/4 with role="banner")
✅ Public Layout: role="banner"
✅ Dashboard Layout: role="banner"
❌ Admin Layout: MISSING role="banner" ← FIX NEEDED
✅ Auth Layout: role="banner" (implicit)
NAVIGATION (4/4 with aria-label)
✅ Public Layout: <nav aria-label="Main navigation">
✅ Dashboard Layout: <nav aria-label="Dashboard">
✅ Admin Layout: <nav aria-label="Administration">
✅ Auth Layout: Implicit in public/dashboard layouts
MAIN CONTENT (4/4 with id + role)
✅ Public Layout: <main id="main-content" role="main">
✅ Dashboard Layout: <main id="main-content" role="main">
✅ Admin Layout: <main id="main-content" role="main">
✅ Auth Layout: <main id="main-content" role="main">
FOOTERS (1/1 with role="contentinfo")
✅ Public Layout: <footer role="contentinfo">
NAVIGATION ASIDES (2/2 with role="navigation")
✅ Dashboard Sidebar: <aside role="navigation">
✅ Admin Sidebar: <aside role="navigation">
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
7⃣ COLOR CONTRAST & THEME SYSTEM
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Status: ⚠️ NEEDS VERIFICATION
Color System Implementation:
File: apps/web/tailwind.config.ts
Format: HSL CSS Variables

# GoodGo Frontend Accessibility Issues - Code Fixes Required
**Date**: 2026-04-10
**Scope**: apps/web (GoodGo Frontend)
**Status**: ACTIONABLE ITEMS - Ready for Implementation
---
## Summary
Found **4 specific accessibility issues** that require code fixes across the GoodGo frontend. Below are the exact file paths, line numbers, problematic code snippets, and required fixes.
---
## ISSUE 1: Form Inputs Missing aria-label or Associated Labels
### 1.1 File Upload Input Without aria-label
**File**: `apps/web/components/listings/image-upload.tsx`
**Line**: 118
**Problem**: Hidden file input has no aria-label or associated label element
**Current Code**:
```tsx
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
onChange={(e) => {
if (e.target.files) addFiles(e.target.files);
e.target.value = '';
}}
/>
```
**Fix Required**: Add `aria-label`
```tsx
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
aria-label="Chọn ảnh để tải lên"
onChange={(e) => {
if (e.target.files) addFiles(e.target.files);
e.target.value = '';
}}
/>
```
---
### 1.2 Search Save Dialog - Text Input Without aria-label
**File**: `apps/web/app/[locale]/(public)/search/page.tsx`
**Line**: 189
**Problem**: Text input for saving search name has no associated label or aria-label
**Current Code**:
```tsx
<input
type="text"
value={saveName}
onChange={(e) => setSaveName(e.target.value)}
placeholder="Tên tìm kiếm (VD: Chung cư Q7 dưới 3 tỷ)"
className="mb-3 w-full rounded-md border bg-background px-3 py-2 text-sm outline-none focus:ring-2 focus:ring-primary"
maxLength={100}
onKeyDown={(e) => e.key === 'Enter' && handleSaveSearch()}
/>
```
**Fix Required**: Add `aria-label`
```tsx
<input
type="text"
value={saveName}
onChange={(e) => setSaveName(e.target.value)}
placeholder="Tên tìm kiếm (VD: Chung cư Q7 dưới 3 tỷ)"
aria-label="Tên bộ lọc tìm kiếm"
className="mb-3 w-full rounded-md border bg-background px-3 py-2 text-sm outline-none focus:ring-2 focus:ring-primary"
maxLength={100}
onKeyDown={(e) => e.key === 'Enter' && handleSaveSearch()}
/>
```
---
### 1.3 Admin Moderation - Select All Checkbox Without aria-label
**File**: `apps/web/app/[locale]/(admin)/admin/moderation/page.tsx`
**Line**: 222
**Problem**: Table header checkbox for "select all" has no aria-label
**Current Code**:
```tsx
<TableHead className="w-10">
<input
type="checkbox"
checked={selected.size === result.data.length && result.data.length > 0}
onChange={toggleSelectAll}
className="rounded border-input"
/>
</TableHead>
```
**Fix Required**: Add `aria-label`
```tsx
<TableHead className="w-10">
<input
type="checkbox"
aria-label="Chọn tất cả tin đăng"
checked={selected.size === result.data.length && result.data.length > 0}
onChange={toggleSelectAll}
className="rounded border-input"
/>
</TableHead>
```
---
### 1.4 Admin Moderation - Row Checkboxes Without aria-label
**File**: `apps/web/app/[locale]/(admin)/admin/moderation/page.tsx`
**Line**: 242
**Problem**: Individual row checkboxes in table have no aria-label
**Current Code**:
```tsx
<TableCell>
<input
type="checkbox"
checked={selected.has(item.listingId)}
onChange={() => toggleSelect(item.listingId)}
className="rounded border-input"
/>
</TableCell>
```
**Fix Required**: Add `aria-label` with dynamic content
```tsx
<TableCell>
<input
type="checkbox"
aria-label={`Chọn tin đăng: ${item.title || item.listingId}`}
checked={selected.has(item.listingId)}
onChange={() => toggleSelect(item.listingId)}
className="rounded border-input"
/>
</TableCell>
```
---
## ISSUE 2: Mock Image Component Missing alt Attribute
### 2.1 Test Mock Image Component
**File**: `apps/web/app/[locale]/(public)/search/__tests__/search.spec.tsx`
**Line**: 46
**Problem**: Mock Image component spreads all props including missing alt attribute
**Current Code**:
```tsx
default: (props: Record<string, unknown>) => <img {...props} />,
```
**Fix Required**: Ensure alt is always included in mock or add default
```tsx
default: (props: Record<string, unknown>) => <img {...props} alt={props.alt || ''} />,
```
OR better approach - require alt in mock setup:
```tsx
default: (props: Record<string, unknown>) => {
if (!props.alt) {
console.warn('Missing alt attribute in Image mock:', props);
}
return <img {...props} alt={props.alt || 'image'} />;
},
```
---
## ISSUE 3: Hidden File Input Needs Better Accessibility
### 3.1 Image Upload Drag-Drop Area Needs Better Labeling
**File**: `apps/web/components/listings/image-upload.tsx`
**Lines**: 86-128
**Problem**: The clickable div that triggers file input has descriptive text but no label element linking to the hidden input
**Current Implementation**:
```tsx
<div
onDragOver={handleDragOver}
onDragLeave={handleDragLeave}
onDrop={handleDrop}
onClick={() => inputRef.current?.click()}
className={cn(...)}
>
<svg>...</svg>
<p className="text-sm font-medium">Kéo thả nh vào đây hoặc nhấp đ chọn</p>
<p className="mt-1 text-xs text-muted-foreground">
JPG, PNG, WebP - Tối đa {maxFiles} nh, mỗi nh 10MB
</p>
<input
ref={inputRef}
type="file"
accept="image/jpeg,image/png,image/webp"
multiple
className="hidden"
onChange={(e) => {...}}
/>
</div>
```
**Recommended Enhancement**: Add proper label or role
```tsx
<div
onDragOver={handleDragOver}
onDragLeave={handleDragLeave}
onDrop={handleDrop}
onClick={() => inputRef.current?.click()}
role="button"
tabIndex={0}
aria-label="Khu vực kéo thả hoặc nhấp để tải ảnh lên"
onKeyDown={(e) => {
if (e.key === 'Enter' || e.key === ' ') {
inputRef.current?.click();
}
}}
className={cn(...)}
>
{/* ... rest of content ... */}
</div>
```
---
## ISSUE 4: Verification of Properly Implemented Accessibility
### ✅ CORRECT - Image Components with alt attributes
The following files already have proper alt attributes and require NO changes:
- `apps/web/components/listings/image-gallery.tsx` - All Image components have alt (lines 34, 77)
- `apps/web/components/listings/image-upload.tsx` - All img tags have alt (line 135-138)
- `apps/web/components/search/property-card.tsx` - Image has alt (line 44)
- `apps/web/app/[locale]/(dashboard)/listings/page.tsx` - All Images have alt (lines 192, 272)
- `apps/web/app/[locale]/(dashboard)/dashboard/page.tsx` - Image has alt (line 252)
- `apps/web/app/[locale]/(admin)/admin/kyc/page.tsx` - All Images have alt (lines 102, 116, 130)
### ✅ CORRECT - Icon-only Buttons with aria-label
The following files already have proper aria-labels and require NO changes:
- `apps/web/components/listings/image-gallery.tsx` - Navigation buttons have aria-labels (lines 47, 54)
- `apps/web/app/[locale]/(public)/layout.tsx` - Mobile menu button has aria-label (line 91)
### ✅ CORRECT - Dialogs with Semantic Titles
The following dialogs already have proper DialogTitle elements and require NO changes:
- `apps/web/app/[locale]/(dashboard)/dashboard/subscription/page.tsx` - DialogTitle present (line 327-329)
- `apps/web/app/[locale]/(admin)/admin/kyc/page.tsx` - Both dialogs have DialogTitle (approval and rejection dialogs)
### ✅ CORRECT - Checkbox with Associated Label
- `apps/web/app/[locale]/(public)/search/page.tsx` (line 199) - Checkbox has associated `<label>` element
---
## Implementation Priority

## Repository Layer
### Domain Interface
```typescript
// domain/repositories/audit-log.repository.ts
export interface IAuditLogRepository {
create(auditLog: CreateAuditLogDto): Promise<AuditLog>;
findMany(params: FindAuditLogsParams): Promise<PaginatedResult<AuditLog>>;
findById(id: string): Promise<AuditLog | null>;
findByAdminId(adminId: string, pagination: Pagination): Promise<PaginatedResult<AuditLog>>;
}
export interface CreateAuditLogDto {
adminId: string;
action: AdminAction;
resourceType: AuditResourceType;
resourceId: string;
changes?: Record<string, any>;
reason?: string;
ipAddress?: string;
userAgent?: string;
status: AuditStatus;
statusCode?: number;
errorMessage?: string;
duration?: number;
}
export interface FindAuditLogsParams {
page: number;
limit: number;
adminId?: string;
action?: AdminAction;
resourceType?: AuditResourceType;
resourceId?: string;
startDate?: Date;
endDate?: Date;
}
```
### Infrastructure Implementation
```typescript
// infrastructure/repositories/prisma-audit-log.repository.ts
@Injectable()
export class PrismaAuditLogRepository implements IAuditLogRepository {
constructor(private readonly prisma: PrismaService) {}
async create(dto: CreateAuditLogDto): Promise<AuditLog> {
return this.prisma.auditLog.create({
data: {
adminId: dto.adminId,
action: dto.action,
resourceType: dto.resourceType,
resourceId: dto.resourceId,
changes: dto.changes,
reason: dto.reason,
ipAddress: dto.ipAddress,
userAgent: dto.userAgent,
status: dto.status,
statusCode: dto.statusCode,
errorMessage: dto.errorMessage,
duration: dto.duration,
},
});
}
async findMany(params: FindAuditLogsParams): Promise<PaginatedResult<AuditLog>> {
const skip = (params.page - 1) * params.limit;
const where: Prisma.AuditLogWhereInput = {
...(params.adminId && { adminId: params.adminId }),
...(params.action && { action: params.action }),
...(params.resourceType && { resourceType: params.resourceType }),
...(params.resourceId && { resourceId: params.resourceId }),
...(params.startDate || params.endDate) && {
createdAt: {
...(params.startDate && { gte: params.startDate }),
...(params.endDate && { lte: params.endDate }),
},
},
};
const [data, total] = await Promise.all([
this.prisma.auditLog.findMany({
where,
skip,
take: params.limit,
orderBy: { createdAt: 'desc' },
}),
this.prisma.auditLog.count({ where }),
]);
return {
data,
total,
page: params.page,
limit: params.limit,
totalPages: Math.ceil(total / params.limit),
};
}
// ... other methods
}
```
---
## Event Listener Implementation
```typescript
// application/listeners/audit-logging.listener.ts
@Injectable()
export class AuditLoggingListener {
constructor(
@Inject(AUDIT_LOG_REPOSITORY) private readonly auditRepo: IAuditLogRepository,
private readonly logger: LoggerService,
) {}
@OnEvent('user.banned', { async: true })
async handleUserBanned(event: UserBannedEvent): Promise<void> {
await this.createAuditLog({
adminId: event.adminId,
action: AdminAction.USER_BANNED,
resourceType: AuditResourceType.USER,
resourceId: event.aggregateId,
reason: event.reason,
status: AuditStatus.SUCCESS,
});
}
@OnEvent('user.unbanned', { async: true })
async handleUserUnbanned(event: UserUnbannedEvent): Promise<void> {
await this.createAuditLog({
adminId: event.adminId,
action: AdminAction.USER_UNBANNED,
resourceType: AuditResourceType.USER,
resourceId: event.aggregateId,
status: AuditStatus.SUCCESS,
});
}
@OnEvent('listing.approved', { async: true })
async handleListingApproved(event: ListingApprovedEvent): Promise<void> {
await this.createAuditLog({
adminId: event.adminId,
action: AdminAction.LISTING_APPROVED,
resourceType: AuditResourceType.LISTING,
resourceId: event.aggregateId,
reason: event.moderationNotes,
status: AuditStatus.SUCCESS,
});
}
@OnEvent('kyc.approved', { async: true })
async handleKycApproved(event: KycApprovedEvent): Promise<void> {
await this.createAuditLog({
adminId: event.adminId,
action: AdminAction.KYC_APPROVED,
resourceType: AuditResourceType.KYC,
resourceId: event.aggregateId,
reason: event.comments,
status: AuditStatus.SUCCESS,
});
}
// ... more handlers ...
private async createAuditLog(dto: CreateAuditLogDto): Promise<void> {
try {
await this.auditRepo.create(dto);
this.logger.log(
`Audit logged: ${dto.action} on ${dto.resourceType}/${dto.resourceId}`,
'AuditLoggingListener',
);
} catch (error) {
this.logger.error(
`Failed to create audit log: ${String(error)}`,
error instanceof Error ? error.stack : undefined,
'AuditLoggingListener',
);
// Don't re-throw to prevent interrupting the main operation
}
}
}
```
---
## Query Handler for Retrieval
```typescript
// application/queries/get-audit-logs/get-audit-logs.handler.ts
export class GetAuditLogsQuery {
constructor(
public readonly page: number,
public readonly limit: number,
public readonly adminId?: string,
public readonly action?: AdminAction,
public readonly resourceType?: AuditResourceType,
public readonly startDate?: Date,
public readonly endDate?: Date,
) {}
}
@QueryHandler(GetAuditLogsQuery)
export class GetAuditLogsHandler implements IQueryHandler<GetAuditLogsQuery> {
constructor(
@Inject(AUDIT_LOG_REPOSITORY) private readonly auditRepo: IAuditLogRepository,
) {}
async execute(query: GetAuditLogsQuery): Promise<PaginatedResult<AuditLog>> {
return this.auditRepo.findMany({
page: query.page,
limit: query.limit,
adminId: query.adminId,
action: query.action,
resourceType: query.resourceType,
startDate: query.startDate,
endDate: query.endDate,
});
}
}
```
---
## Controller Endpoint
```typescript
// presentation/controllers/admin.controller.ts (add to existing file)
@Get('audit-logs')
@ApiOperation({ summary: 'Get audit logs with filters' })
@ApiQuery({ name: 'page', required: false, type: Number })
@ApiQuery({ name: 'limit', required: false, type: Number })
@ApiQuery({ name: 'adminId', required: false, type: String })
@ApiQuery({ name: 'action', required: false, enum: AdminAction })
@ApiQuery({ name: 'resourceType', required: false, enum: AuditResourceType })
@ApiQuery({ name: 'startDate', required: false, type: String })
@ApiQuery({ name: 'endDate', required: false, type: String })
@ApiResponse({ status: 200, description: 'Audit logs retrieved' })
async getAuditLogs(
@Query() query: GetAuditLogsQueryDto,
): Promise<PaginatedResult<AuditLog>> {
return this.queryBus.execute(
new GetAuditLogsQuery(
query.page ?? 1,
query.limit ?? 20,
query.adminId,
query.action,
query.resourceType,
query.startDate ? new Date(query.startDate) : undefined,
query.endDate ? new Date(query.endDate) : undefined,
),
);
}
```
---
## DI Registration
```typescript
// admin.module.ts (update existing)
import { AUDIT_LOG_REPOSITORY, IAuditLogRepository } from '...';
import { PrismaAuditLogRepository } from '...';
import { AuditLoggingListener } from '...';
const QueryHandlers = [
// ... existing handlers ...
GetAuditLogsHandler, // NEW
];
const EventListeners = [
UserBannedListener,
UserDeactivatedListener,
AuditLoggingListener, // NEW
];
@Module({
imports: [CqrsModule, AuthModule, ListingsModule, SubscriptionsModule],
controllers: [AdminController, AdminModerationController],
providers: [
// Repositories
{ provide: ADMIN_QUERY_REPOSITORY, useClass: PrismaAdminQueryRepository },
{ provide: AUDIT_LOG_REPOSITORY, useClass: PrismaAuditLogRepository }, // NEW
// CQRS
...CommandHandlers,
...QueryHandlers,
// Event Listeners
...EventListeners,
],
})
export class AdminModule {}
```
---
## Testing Strategy
### Unit Test (AuditLoggingListener)
```typescript
describe('AuditLoggingListener', () => {
let listener: AuditLoggingListener;
let auditRepo: MockRepository<IAuditLogRepository>;
beforeEach(() => {
auditRepo = mockRepository();
listener = new AuditLoggingListener(auditRepo, mockLogger());
});
it('should create audit log on user.banned event', async () => {
const event = new UserBannedEvent('usr_123', 'admin_456', 'Violation');
await listener.handleUserBanned(event);
expect(auditRepo.create).toHaveBeenCalledWith(
expect.objectContaining({
adminId: 'admin_456',
action: AdminAction.USER_BANNED,
resourceId: 'usr_123',
reason: 'Violation',
})
);
});
it('should handle repository errors gracefully', async () => {
auditRepo.create.mockRejectedValueOnce(new Error('DB error'));
const event = new UserBannedEvent('usr_123', 'admin_456', 'Violation');
// Should not throw
await expect(listener.handleUserBanned(event)).resolves.toBeUndefined();
});
});
```
### Integration Test
```typescript
describe('Audit Logging Integration', () => {
let app: INestApplication;
let prisma: PrismaService;
beforeAll(async () => {
const module = await Test.createTestingModule({
imports: [AdminModule, SharedModule],
}).compile();
app = module.createNestApplication();
prisma = module.get(PrismaService);
});
it('should log admin action to database', async () => {
const admin = await createTestAdmin(prisma);
const user = await createTestUser(prisma);
await app.get(CommandBus).execute(
new BanUserCommand(user.id, admin.id, 'Test ban')
);
const auditLog = await prisma.auditLog.findFirst({
where: { adminId: admin.id, resourceId: user.id },
});
expect(auditLog).toBeDefined();
expect(auditLog?.action).toBe(AdminAction.USER_BANNED);
expect(auditLog?.reason).toBe('Test ban');
});
});
```
---
## Summary
This architecture ensures:
**Separation of Concerns** - Audit logging as separate concern via event listener
**Non-Blocking** - Audit logging happens async, doesn't block main operation
**Reusability** - Single listener handles all admin actions
**Consistency** - Follows existing DDD/CQRS patterns
**Queryability** - Full audit trail with filtering capabilities
**Compliance** - Complete record of who did what and when

- ✅ No AdminAction model found
- ✅ Opportunity to implement from scratch following project patterns
---
## 3. ADMIN CONTROLLER ACTIONS & FLOW
### AdminController (User Management)
**File**: `presentation/controllers/admin.controller.ts`
#### Endpoints:
1. **GET /admin/users** - List users with filters
- Query params: page, limit, role, isActive, search
- Returns: UserListResult (paginated)
2. **GET /admin/users/:id** - Get user details
- Returns: UserDetail (full profile + activity)
3. **PATCH /admin/users/status** - Update user active status
- Body: `UpdateUserStatusDto` {userId, isActive, reason}
- Current user (admin) captured via `@CurrentUser()`
- Command: `UpdateUserStatusCommand(userId, adminId, isActive, reason)`
4. **POST /admin/users/ban** - Ban/unban user
- Body: `BanUserDto` {userId, reason, unban?}
- Command: `BanUserCommand(userId, adminId, reason, unban)`
- **Key**: Admin ID is captured from JWT
5. **POST /admin/subscriptions/adjust** - Adjust subscription
- Body: `AdjustSubscriptionDto` {userId, newPlanTier, reason}
- Command: `AdjustSubscriptionCommand(userId, adminId, newPlanTier, reason)`
6. **GET /admin/dashboard** - Dashboard stats
- Query: `GetDashboardStatsQuery`
7. **GET /admin/revenue** - Revenue statistics
- Query params: startDate, endDate, groupBy (day/month)
### AdminModerationController (Content Moderation)
**File**: `presentation/controllers/admin-moderation.controller.ts`
#### Endpoints:
1. **GET /admin/moderation** - Get moderation queue
- Query params: page, limit
- Returns: ModerationQueueResult
2. **POST /admin/moderation/approve** - Approve listing
- Body: `ApproveListingDto` {listingId, moderationNotes}
- Command: `ApproveListingCommand(listingId, adminId, moderationNotes)`
- Event: `ListingApprovedEvent` published
3. **POST /admin/moderation/reject** - Reject listing
- Body: `RejectListingDto` {listingId, reason}
- Command: `RejectListingCommand(listingId, adminId, reason)`
- Event: `ListingRejectedEvent` published
4. **POST /admin/moderation/bulk** - Bulk moderate
- Body: `BulkModerateDto` {listingIds[], action, reason}
- Command: `BulkModerateListingsCommand(...)`
5. **GET /admin/kyc** - Get KYC queue
- Returns: KycQueueResult (users with PENDING KYC)
6. **POST /admin/kyc/approve** - Approve KYC
- Body: `ApproveKycDto` {userId, comments}
- Command: `ApproveKycCommand(userId, adminId, comments)`
- Event: `KycApprovedEvent` published
7. **POST /admin/kyc/reject** - Reject KYC
- Body: `RejectKycDto` {userId, reason}
- Command: `RejectKycCommand(userId, adminId, reason)`
- Event: `KycRejectedEvent` published
### Key Pattern: Admin ID Capture
```typescript
@Post('moderation/approve')
async approveListing(
@Body() dto: ApproveListingDto,
@CurrentUser() user: JwtPayload, // ← Admin's identity
) {
return this.commandBus.execute(
new ApproveListingCommand(dto.listingId, user.sub, dto.moderationNotes)
);
// user.sub = admin's userId
}
```
---
## 4. EXISTING EVENT/LOGGING INFRASTRUCTURE
### DomainEvent Interface
**Location**: `@modules/shared`
```typescript
// All domain events implement DomainEvent:
export interface DomainEvent {
readonly eventName: string;
readonly occurredAt: Date;
readonly aggregateId: string; // What changed (user/listing ID)
}
```
### Example: UserBannedEvent
```typescript
export class UserBannedEvent implements DomainEvent {
readonly eventName = 'user.banned';
readonly occurredAt = new Date();
constructor(
public readonly aggregateId: string, // userId
public readonly adminId: string, // ← Admin who performed action
public readonly reason: string,
) {}
}
```
### Example: ListingApprovedEvent
```typescript
export class ListingApprovedEvent implements DomainEvent {
readonly eventName = 'listing.approved';
readonly occurredAt = new Date();
constructor(
public readonly aggregateId: string, // listingId
public readonly adminId: string, // ← Admin who approved
public readonly moderationNotes?: string,
) {}
}
```
### Event Publishing & Listening
**Pattern Used**: NestJS CQRS + EventEmitter
#### Publishing (in Command Handlers):
```typescript
@CommandHandler(BanUserCommand)
export class BanUserHandler implements ICommandHandler<BanUserCommand> {
constructor(
private readonly userRepo: IUserRepository,
private readonly eventBus: EventBus, // ← Injected
) {}
async execute(command: BanUserCommand): Promise<BanUserResult> {
// ... business logic ...
this.eventBus.publish(
new UserBannedEvent(user.id, command.adminId, command.reason)
);
return { userId: user.id, isActive: false, message: 'Người dùng đã bị ban' };
}
}
```
#### Listening (in Event Listeners):
```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'
);
// Side effects: deactivate listings, send notification, etc.
const deactivated = await this.prisma.listing.updateMany({
where: { sellerId: event.aggregateId, status: { in: ['ACTIVE', ...] } },
data: { status: 'EXPIRED' },
});
// Send email notification
await this.commandBus.execute(
new SendNotificationCommand(user.id, 'EMAIL', 'user.banned', ...)
);
}
}
```
### EventBus Architecture
- **Module**: `@nestjs/cqrs`
- **Setup**: `CqrsModule.forRoot()` in `app.module.ts`
- **Mechanism**:
- Commands publish events via `eventBus.publish(event)`
- Listeners subscribe via `@OnEvent(eventName, { async: true })`
- Events are async by default (non-blocking)
---
## 5. LOGGER SERVICE
**Location**: `apps/api/src/modules/shared/infrastructure/logger.service.ts`
### Features
- **Provider**: Pino (structured logging)
- **PII Redaction**: Automatic masking of sensitive fields
- Redacted paths: password, token, email, phone, kycData, creditCard, etc.
- Censor pattern: `[REDACTED]`
- **Environment-aware**:
- Dev: Pretty-printed with colors
- Prod: Structured JSON
- **Methods**:
- `log(message, context)`
- `error(message, trace, context)`
- `warn(message, context)`
- `debug(message, context)`
- `verbose(message, context)`
- `child(bindings)` - Child logger with context binding
### Redacted Fields
```typescript
redact: {
paths: [
'password', 'passwordHash', 'token', 'accessToken', 'refreshToken',
'secret', 'authorization', 'cookie', 'creditCard', 'cardNumber',
'cvv', 'ssn', 'cmnd', 'cccd', 'email', 'phone', 'kycData',
'idNumber', 'identityNumber', 'dateOfBirth', 'dob', 'address',
'bankAccount', 'accountNumber', 'apiKey', 'privateKey', 'encryptionKey',
'req.headers.authorization', 'req.headers.cookie',
'user.email', 'user.phone', 'user.kycData',
'body.password', 'body.token', 'body.email', 'body.phone',
],
censor: '[REDACTED]',
}
```
---
## 6. EXCEPTION HANDLING & FILTERS
### GlobalExceptionFilter
**Location**: `apps/api/src/modules/shared/infrastructure/filters/global-exception.filter.ts`
```typescript
@Catch()
export class GlobalExceptionFilter implements ExceptionFilter {
constructor(private readonly logger: LoggerService) {}
catch(exception: unknown, host: ArgumentsHost): void {
const ctx = host.switchToHttp();
const response = ctx.getResponse<Response>();
const request = ctx.getRequest<Request>();
const correlationId = (request.headers['x-correlation-id'] as string) ?? undefined;
const errorResponse = this.buildErrorResponse(exception, correlationId);
this.logger.error(
`[${errorResponse.errorCode}] ${errorResponse.message}`,
exception instanceof Error ? exception.stack : undefined,
'GlobalExceptionFilter'
);
response.status(errorResponse.statusCode).json(errorResponse);
}
}
```
### Error Response Structure
```typescript
interface ErrorResponseBody {
statusCode: number;
errorCode: ErrorCode; // Enum with values like VALIDATION_FAILED, NOT_FOUND, etc.
message: string;
details?: Record<string, unknown>;
correlationId?: string;
timestamp: string;
}
```
### Domain Exceptions
```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);
}
}
// Specific exceptions:
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 { ... }
```
---
## 7. SECURITY & GUARDS
### Role-Based Access Control (RBAC)
**Location**: `apps/api/src/modules/auth/presentation/decorators/`
#### Pattern:
```typescript
@Controller('admin')
@UseGuards(JwtAuthGuard, RolesGuard)
@Roles('ADMIN')
export class AdminController {
// All endpoints require ADMIN role
}
```
#### Roles Guard Flow:
1. `JwtAuthGuard` - Validates JWT token
2. `RolesGuard` - Checks `@Roles()` decorator against user.role
3. Both decorators from `@modules/auth`
### Rate Limiting
**Setup**: ThrottlerModule + ThrottlerBehindProxyGuard
- Default: 60 requests per 60 seconds per IP
- Auth endpoints: 10 requests per 60 seconds
- Payment callbacks: 20 requests per 60 seconds
---
## 8. DDD LAYER STRUCTURE
### Architectural Layers
```
Presentation Layer (Controllers)
↓ (DTO validation)
Application Layer (Commands/Queries/Handlers/Listeners)
↓ (Command/Query)
Domain Layer (Events, Interfaces, Business Rules)
↓ (Repository calls, Event publishing)
Infrastructure Layer (Prisma, Database)
```
### Command Handler Pattern
```typescript
// 1. Command (DTO-like)
export class BanUserCommand {
constructor(
public readonly userId: string,
public readonly adminId: string,
public readonly reason: string,
public readonly unban: boolean = false,
) {}
}
// 2. Handler (Business Logic + Event Publishing)
@CommandHandler(BanUserCommand)
export class BanUserHandler implements ICommandHandler<BanUserCommand> {
constructor(
@Inject(USER_REPOSITORY) private readonly userRepo: IUserRepository,
private readonly eventBus: EventBus,
) {}
async execute(command: BanUserCommand): Promise<BanUserResult> {
// Business logic
const user = await this.userRepo.findById(command.userId);
if (!user) throw new NotFoundException(...);
user.deactivate();
await this.userRepo.update(user);
// Publish event
this.eventBus.publish(
new UserBannedEvent(user.id, command.adminId, command.reason)
);
return { userId: user.id, isActive: false, message: '...' };
}
}
// 3. Event (Side-effect Trigger)
export class UserBannedEvent implements DomainEvent {
readonly eventName = 'user.banned';
readonly occurredAt = new Date();
constructor(
public readonly aggregateId: string,
public readonly adminId: string,
public readonly reason: string,
) {}
}
// 4. Listener (Side Effects - triggered by Event)
@Injectable()
export class UserBannedListener {
@OnEvent('user.banned', { async: true })
async handle(event: UserBannedEvent): Promise<void> {
// Send notification, update related data, etc.
}
}
```
### Query Handler Pattern
```typescript
// Query (read operation definition)
export class GetDashboardStatsQuery {}
// Handler (fetch & return data)
@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();
}
}
```
### Repository Pattern
```typescript
// Domain interface (no implementation details)
export interface IAdminQueryRepository {
getModerationQueue(page: number, limit: number): Promise<ModerationQueueResult>;
getDashboardStats(): Promise<DashboardStats>;
// ... more methods
}
// Infrastructure implementation (Prisma-specific)
@Injectable()
export class PrismaAdminQueryRepository implements IAdminQueryRepository {
constructor(private readonly prisma: PrismaService) {}
async getModerationQueue(page: number, limit: number): Promise<ModerationQueueResult> {
// Prisma queries here
}
}
// DI Token
export const ADMIN_QUERY_REPOSITORY = Symbol('ADMIN_QUERY_REPOSITORY');
// Module registration
@Module({
providers: [
{ provide: ADMIN_QUERY_REPOSITORY, useClass: PrismaAdminQueryRepository },
],
})
export class AdminModule {}
```
---
## 9. MODULE BOOTSTRAP
### AdminModule Setup
**File**: `apps/api/src/modules/admin/admin.module.ts`
```typescript
@Module({
imports: [CqrsModule, AuthModule, ListingsModule, SubscriptionsModule],
controllers: [AdminController, AdminModerationController],
providers: [
// Repositories
{ provide: ADMIN_QUERY_REPOSITORY, useClass: PrismaAdminQueryRepository },
// CQRS Handlers
...CommandHandlers, // 8 command handlers
...QueryHandlers, // 6 query handlers
// Event Listeners
UserBannedListener,
UserDeactivatedListener,
],
})
export class AdminModule {}
```
### Global Setup
**File**: `apps/api/src/app.module.ts`
```typescript
@Module({
imports: [
SentryModule.forRoot(),
CqrsModule.forRoot(), // ← CQRS with Event Bus
ScheduleModule.forRoot(),
ThrottlerModule.forRoot(...), // ← Rate limiting
// ... other modules including AdminModule
],
providers: [
{
provide: APP_FILTER,
useClass: SentryGlobalFilter,
},
{
provide: APP_GUARD,
useClass: ThrottlerBehindProxyGuard,
},
{
provide: APP_INTERCEPTOR,
useClass: HttpMetricsInterceptor,
},
],
})
export class AppModule implements NestModule {
configure(consumer: MiddlewareConsumer) {
consumer.apply(SanitizeInputMiddleware).forRoutes('*');
consumer.apply(CsrfMiddleware).exclude(...).forRoutes('*');
}
}
```
---
## 10. EXISTING INTERCEPTOR PATTERNS
### HttpMetricsInterceptor
**Location**: `@modules/metrics`
- Injected globally via `APP_INTERCEPTOR`
- Tracks HTTP request/response metrics
- Could serve as a template for audit logging interceptor
### CSRF Middleware
**Location**: `@modules/shared/infrastructure/middleware/csrf.middleware`
- Double-submit cookie pattern
- Validates on state-changing methods
- Provides model for request context enhancement
---
## 11. SUMMARY FOR AUDIT LOGGING IMPLEMENTATION
### What's Already in Place ✅
1. **Event-driven architecture** - Commands publish events, listeners handle side effects
2. **Admin identity capture** - All admin actions have `adminId` in commands
3. **Logger service** - Pino-based with PII redaction
4. **Exception handling** - Global filter + DomainException hierarchy
5. **RBAC** - @Roles('ADMIN') guard in place
6. **Module bootstrap** - Clear DI pattern ready for audit repository injection
7. **DTO validation** - All inputs validated via class-validator
### What Needs to Be Built 🚀
1. **AuditLog Prisma Model** - Store in database
2. **AuditLoggingInterceptor** - Capture HTTP context (IP, timestamp, endpoint)
3. **AuditEvent Domain Event** - Extend domain events for audit purposes
4. **AuditLoggingListener** - Event listener that persists to AuditLog
5. **AuditLog Repository** - CRUD operations for AuditLog
6. **Query Handler** - Retrieve audit logs with filters (date range, admin, action type)
7. **Controller Endpoint** - GET /admin/audit-logs for viewing audit trail
### Key Integration Points
1. Commands already pass `adminId` → Use in AuditLoggingListener
2. Domain events already published → Hook audit listener to relevant events
3. HTTPContext (IP, user-agent, etc.) → Capture in interceptor
4. Logger service available → Use for structured logging
5. Repository pattern established → Follow for AuditLog repository
### Recommended Audit Fields
- `id` (primary key)
- `adminId` (who performed action)
- `adminName` (for denormalization)
- `action` (e.g., 'user.banned', 'listing.approved')
- `resourceType` (e.g., 'user', 'listing')
- `resourceId` (what was affected)
- `changes` (JSON of what changed - before/after)
- `reason` (from DTO if provided)
- `ipAddress` (from request)
- `userAgent` (from request)
- `status` (success/failure)
- `statusCode` (HTTP status)
- `errorMessage` (if failed)
- `duration` (milliseconds)
- `createdAt` (timestamp)

# Quick File Reference for Admin Module Audit Logging
## MUST READ FIRST (15 min total)
### 1. Main Controllers (Define what actions need audit)
-`apps/api/src/modules/admin/presentation/controllers/admin.controller.ts` (155 lines)
- User management: ban, update status, adjust subscription
- All endpoints have @CurrentUser() decorator to capture admin ID
-`apps/api/src/modules/admin/presentation/controllers/admin-moderation.controller.ts` (157 lines)
- Listing approval/rejection
- KYC approval/rejection
- Bulk moderation
### 2. Command Handlers (Where to hook audit logging)
Each command publishes a domain event. Audit logging listener should listen to these events.
**Ban User Flow:**
- Input: `apps/api/src/modules/admin/presentation/dto/ban-user.dto.ts`
- Command: `apps/api/src/modules/admin/application/commands/ban-user/ban-user.command.ts`
- Handler: `apps/api/src/modules/admin/application/commands/ban-user/ban-user.handler.ts` (70 lines)
- Line 62: `this.eventBus.publish(new UserBannedEvent(...))`
**Approve Listing Flow:**
- Input: `apps/api/src/modules/admin/presentation/dto/approve-listing.dto.ts`
- Command: `apps/api/src/modules/admin/application/commands/approve-listing/approve-listing.command.ts`
- Handler: `apps/api/src/modules/admin/application/commands/approve-listing/approve-listing.handler.ts` (52 lines)
- Line 42-44: `this.eventBus.publish(new ListingApprovedEvent(...))`
### 3. Domain Events (What information is published)
```
apps/api/src/modules/admin/domain/events/
├── user-banned.event.ts
├── user-unbanned.event.ts
├── listing-approved.event.ts
├── listing-rejected.event.ts
├── subscription-adjusted.event.ts
├── kyc-approved.event.ts
└── kyc-rejected.event.ts
```
Each event has:
- `eventName` (e.g., 'user.banned')
- `occurredAt` (timestamp)
- `aggregateId` (userId or listingId)
- `adminId` (the admin who performed the action)
- Additional context (reason, notes, etc.)
### 4. Existing Event Listener Pattern (Template)
-`apps/api/src/modules/admin/application/listeners/user-banned.listener.ts` (52 lines)
- Shows @OnEvent() decorator
- Shows how to access event data
- Shows side effects (deactivate listings, send notification)
- **THIS IS YOUR TEMPLATE FOR AUDIT LOGGING LISTENER**
### 5. Logger Service (Where to log)
-`apps/api/src/modules/shared/infrastructure/logger.service.ts` (65 lines)
- Pino-based structured logging
- Auto PII redaction
- Methods: log(), error(), warn(), debug(), verbose()
### 6. Exception Filter (For error logging)
-`apps/api/src/modules/shared/infrastructure/filters/global-exception.filter.ts` (145 lines)
- Catches all exceptions
- Logs with correlationId
- Could capture failed admin actions
---
## ARCHITECTURE REFERENCES
### Repository Pattern
- Domain Interface: `apps/api/src/modules/admin/domain/repositories/admin-query.repository.ts`
- Prisma Implementation: `apps/api/src/modules/admin/infrastructure/repositories/prisma-admin-query.repository.ts`
- **FOLLOW THIS PATTERN** for AuditLog repository
### Module Bootstrap
- `apps/api/src/modules/admin/admin.module.ts` (64 lines)
- Shows how to register repositories via DI
- Shows how to register listeners
- Shows how to import CQRS module
### Global App Setup
- `apps/api/src/app.module.ts` (100+ lines)
- Shows APP_FILTER, APP_GUARD, APP_INTERCEPTOR registration
- Shows CqrsModule.forRoot() setup
- Shows middleware configuration
---
## PRISMA SCHEMA
### Current Models (What we're auditing)
- `prisma/schema.prisma` (602 lines total)
**User Model** (lines 34-71):
- Fields to audit: isActive, kycStatus, role
**Listing Model** (lines 227-276):
- Fields to audit: status, moderationScore, moderationNotes
**NO AUDIT MODEL YET** - Opportunity to create from scratch
---
## EXACT ENDPOINTS TO AUDIT (From Controllers)
### AdminController Actions:
1. `PATCH /admin/users/status` - Update user active status
2. `POST /admin/users/ban` - Ban/unban user
3. `POST /admin/subscriptions/adjust` - Adjust subscription
### AdminModerationController Actions:
1. `POST /admin/moderation/approve` - Approve listing
2. `POST /admin/moderation/reject` - Reject listing
3. `POST /admin/moderation/bulk` - Bulk moderate listings
4. `POST /admin/kyc/approve` - Approve KYC
5. `POST /admin/kyc/reject` - Reject KYC
Each action:
- Already captures admin ID from JWT
- Already publishes a domain event
- Already has a command handler
- Needs: Audit logging listener to capture to database
---
## DEPENDENCIES ALREADY IMPORTED
### In AdminModule:
```typescript
// Already available:
- CqrsModule (from @nestjs/cqrs)
- AuthModule (auth guards/decorators)
- ListingsModule (for listing operations)
- SubscriptionsModule (for subscription operations)
// In providers:
- CommandHandlers (8 total)
- QueryHandlers (6 total)
- Event Listeners (2 existing + need to add AuditLoggingListener)
```
### From SharedModule:
- `PrismaService` (database)
- `LoggerService` (logging)
- Exception types (NotFoundException, ValidationException, etc.)
---
## IMPLEMENTATION CHECKLIST
### Phase 1: Database & Repository
- [ ] Create AuditLog Prisma model in schema.prisma
- [ ] Create IAuditLogRepository interface
- [ ] Create PrismaAuditLogRepository implementation
- [ ] Add to AdminModule providers
### Phase 2: Events & Listeners
- [ ] Create AuditEvent domain event (if needed as wrapper)
- [ ] Create AuditLoggingListener to @OnEvent() for all admin events
- [ ] Inject AuditLogRepository into listener
- [ ] Persist audit records on event
### Phase 3: Query & API
- [ ] Create GetAuditLogsQuery
- [ ] Create GetAuditLogsHandler
- [ ] Create IAuditLogQueryRepository method
- [ ] Add to QueryHandlers in module
### Phase 4: Controller Endpoint
- [ ] Add GET /admin/audit-logs endpoint
- [ ] Add filtering DTOs (dateRange, adminId, actionType, resourceId)
- [ ] Add pagination support
### Phase 5: Testing
- [ ] Unit tests for AuditLoggingListener
- [ ] Integration tests for audit persistence
- [ ] E2E tests for audit log retrieval
---
## CRITICAL PATTERNS TO FOLLOW
### 1. Command Pattern (Already Used)
```typescript
// DTOs validate input
// Commands encapsulate business intent
// Handlers execute + publish events
// Events trigger side effects via listeners
```
### 2. DDD Layer Structure
```
Presentation (DTO validation)
Application (Command/Query execution + Event publishing)
Domain (Event definitions, Repository interfaces)
Infrastructure (Database implementation)
```
### 3. Dependency Injection
```typescript
// Always use Symbol for tokens:
export const AUDIT_LOG_REPOSITORY = Symbol('AUDIT_LOG_REPOSITORY');
// Register in module:
{ provide: AUDIT_LOG_REPOSITORY, useClass: PrismaAuditLogRepository }
// Inject in service:
constructor(
@Inject(AUDIT_LOG_REPOSITORY) private readonly auditRepo: IAuditLogRepository,
) {}
```
### 4. Event Listener Pattern
```typescript
@Injectable()
export class AuditLoggingListener {
constructor(
@Inject(AUDIT_LOG_REPOSITORY) private readonly auditRepo: IAuditLogRepository,
private readonly logger: LoggerService,
) {}
@OnEvent('user.banned', { async: true })
async handleUserBanned(event: UserBannedEvent): Promise<void> {
// Extract data from event
// Persist to database
// Log if successful/failed
}
}
```

# GoodGo Platform API - Comprehensive Code Audit Report
**Date:** April 10, 2026
**Scope:** `/apps/api/` | NestJS Backend
**Codebase Size:** ~22K LOC (prod) | ~20K LOC (tests) | 207 test files
---
## 1. MODULE STRUCTURE & DDD ADHERENCE
### ✅ **STRONG: Full DDD Layer Implementation**
All 16 modules follow strict DDD separation:
- **Modules:** auth, listings, payments, subscriptions, admin, analytics, search, notifications, mcp, metrics, agents, inquiries, leads, reviews, health, shared
- **Layer Structure:** `domain/` (entities, VOs, repositories) → `application/` (commands, queries, handlers) → `infrastructure/` (services, strategies, repos) → `presentation/` (controllers, DTOs, guards)
- **CQRS Pattern:** Consistently implemented with CommandBus & QueryBus in auth, payments, subscriptions modules
- **All MVP modules present:** ✓ auth, ✓ listings, ✓ payments, ✓ subscriptions, ✓ admin, ✓ analytics, ✓ search, ✓ notifications, ✓ mcp, ✓ metrics + 6 additional (agents, inquiries, leads, reviews, health)
**Severity:** LOW (architecture excellent)
---
## 2. CODE HEALTH & TYPE SAFETY
### ✅ **EXCELLENT: TypeScript Strict Mode**
```json
"strict": true
"noUncheckedIndexedAccess": true
"noImplicitOverride": true
"noPropertyAccessFromIndexSignature": true
"skipLibCheck": false
```
- **Result Type Pattern:** Implemented in `shared/domain/result.ts` with `.match()`, `.map()`, `.andThen()`
- **Error Handling:** 46 instances of explicit throws (exceptions over bare throws)
- **No type shortcuts:** Zero `: any` types in production code
- **No console logs:** Enforced via Pino structured logging
- **No hardcoded values:** All secrets use `process.env` with validation
**Severity:** LOW (exemplary)
---
## 3. TESTING
### ✅ **COMPREHENSIVE: 207 test files, ~50% code coverage**
- **Test Structure:** Unit tests (`.spec.ts`), integration tests (`.integration.spec.ts`)
- **Test Framework:** Vitest with Node environment
- **Key Coverage:**
- Auth handlers: 8 spec files (register, login, verify-kyc, deletion, export-user)
- Payments: Full CQRS handlers tested
- Listings: Media storage, status updates
- Subscriptions: Quota, metering, upgrades
- **Test Ratio:** ~0.93:1 (20.4K test LOC : 21.9K prod LOC)
- **Missing:** No e2e tests configured; only unit + integration
⚠️ **MEDIUM:** Integration test suite not wired to CI/CD; needs `vitest.integration.config.ts` execution
**Severity:** MEDIUM (strong unit coverage, missing e2e)
---
## 4. DEPENDENCIES & SECURITY
### ✅ **CURRENT: All dependencies up-to-date (NestJS 11, Prisma 7.7, TypeScript 6)**
```
@nestjs/*: ^11.0
@prisma/*: ^7.7.0
typescript: ^6.0.2
passport: ^0.7.0, @nestjs/jwt: ^11.0.2
helmet: ^8.1.0
sentry: ^10.47.0
```
**Audit Findings:**
- ✅ No known CVEs in direct dependencies
- ✅ Helmet configured with CSP, HSTS, COEP, COOP
- ✅ Sentry profiling enabled for error tracking
- ✅ Database adapter: `@prisma/adapter-pg` v7.7.0
⚠️ **LOW:** Package lock strategy unclear (monorepo uses `workspace:*`); ensure pnpm-lock.yaml is committed
**Severity:** LOW (dependencies clean)
---
## 5. SECURITY AUDIT
### ✅ **STRONG: Multi-layered security controls**
#### **Environment Validation** (CRITICAL)
```typescript
// Enforced at app bootstrap (main.ts)
- ALWAYS_REQUIRED: JWT_SECRET, JWT_REFRESH_SECRET
- PRODUCTION_ONLY: DATABASE_URL, CORS_ORIGINS, REDIS_HOST, KYC_ENCRYPTION_KEY
- MINIMUM_SECRET_LENGTH: 32 chars (256-bit equiv.)
- FORBIDDEN_VALUES: placeholder, test, default, change_me, xxx, etc.
```
**Severity:** LOW (excellent validation)
#### **Authentication & Authorization**
- ✅ JWT + refresh token strategy (15m expiry, audience/issuer set)
- ✅ Passport.js guards: JwtAuthGuard, LocalAuthGuard, RolesGuard
- ✅ Multi-OAuth: Google, Zalo
- ✅ Secrets retrieved via ConfigService, not environment directly
#### **CSRF Protection**
- ✅ Double-submit cookie pattern (CsrfMiddleware in shared)
- ✅ X-CSRF-Token header validated on state-changing methods
- ✅ Health endpoints excluded to prevent cookie pollution
#### **Input Sanitization**
- ✅ Global ValidationPipe: whitelist, forbidNonWhitelisted, transform enabled
- ✅ SanitizeInputMiddleware applied to all routes (using `sanitize-html`)
- ✅ Prisma uses parameterized queries (no SQL injection risk detected)
- Only `Prisma.sql` template literal with `Prisma.join()` found (safe)
#### **Rate Limiting**
- ✅ ThrottlerModule with per-route overrides:
- default: 60 req/60s
- auth: 10 req/60s
- payment-callback: 20 req/60s
#### **CORS Configuration**
- ✅ Configurable allowed origins (required in production)
- ✅ Credentials: true, Methods: GET/POST/PUT/PATCH/DELETE, maxAge: 86400
#### **Security Headers (Helmet)**
```
- Content-Security-Policy: 'self' + CDN exceptions (reviewable)
- HSTS: 31536000s, preload enabled
- X-Frame-Options: deny
- Cross-Origin policies: COEP, COOP enabled
- Referrer-Policy: strict-origin-when-cross-origin
```
⚠️ **MEDIUM:** CSP allows `'unsafe-inline'` for scripts/styles
```javascript
scriptSrc: ["'self'", "'unsafe-inline'", 'https://cdn.jsdelivr.net']
```
**Recommendation:** Move to nonce-based CSP in production.
#### **Data Protection**
- ✅ KYC data encrypted at rest (Prisma field encryption via KYC_ENCRYPTION_KEY)
- ✅ Soft deletes: `deletedAt`, `deletionScheduledAt` fields (GDPR compliance path)
- ✅ User deletion workflow: RequestUserDeletion → 30-day grace → ProcessScheduledDeletions
⚠️ **LOW:** No mention of bcrypt cost factor; assume default (10) is acceptable
**Severity:** MEDIUM (CSP policy review needed; otherwise strong)
---
## 6. DATABASE & SCHEMA
### ✅ **SOLID: Prisma 7.7 + PostgreSQL 16 + PostGIS**
- **Schema File:** `/prisma/schema.prisma` (well-structured)
- **Migrations:** 11 SQL migrations tracked (evolution visible)
- **Key Tables:**
- User (with soft delete, KYC status, roles: BUYER/SELLER/AGENT/ADMIN)
- RefreshToken (TTL-based, indexed by userId)
- OAuthAccount (Google, Zalo providers)
- Listing, Property (with PostGIS geometry for geo queries)
- Subscription, Payment, Transaction
- Inquiry, Review, SavedSearch
**Indexing Strategy:**
- ✅ Single-column indexes on hot queries (role, kycStatus, isActive, createdAt)
- ✅ Composite indexes (role + isActive + createdAt DESC) for admin queries
- ✅ Foreign keys with cascade rules checked
⚠️ **LOW:** No explicit CASCADE/RESTRICT rules visible; verify orphaned data handling in deletes
**Severity:** LOW (schema well-designed)
---
## 7. API ENDPOINTS & ROUTES
### ✅ **COMPREHENSIVE: 105+ route decorators across 16 modules**
**Endpoints by module:**
- **Auth:** Register, Login, RefreshToken, VerifyKyc, RequestUserDeletion, ExportUserData, GetProfile, OAuthCallbacks
- **Listings:** CreateListing, UpdateListing, GetListing, ListListings, UpdateStatus, UploadMedia, DeleteMedia
- **Payments:** CreatePayment, GetPaymentStatus, ListTransactions, HandleCallback, RefundPayment
- **Subscriptions:** GetPlan, CreateSubscription, UpgradeSubscription, CancelSubscription, CheckQuota, GetBillingHistory
- **Search:** FullTextSearch, GeoSearch, SavedSearches
- **Admin:** UserModeration, Analytics Dashboard, PaymentReports
- **Notifications:** GetHistory, UpdatePreferences
- **Reviews:** CreateReview, ListReviews, UpdateReview
- **Agents:** GetAgentProfile, ListAgents, GetAgentStats
- **Analytics:** PriceAnalytics, MarketReports, MetricsExport
- **MCP:** TransportController (Model Context Protocol server transport)
**Versioning:** Global `/api/v1/` prefix with health endpoints excluded
**Severity:** LOW (routes well-organized)
---
## 8. CONFIGURATION & ENV MANAGEMENT
### ✅ **STRICT: Comprehensive env validation**
- **Validation Location:** `shared/infrastructure/env-validation.ts` (called at bootstrap)
- **Error Handling:** Throws on missing critical vars (fail-fast)
- **Warnings:** Logged for optional payment/storage vars if unset
- **Supported Payment Gateways:**
- VNPay (VNPAY_TMN_CODE, VNPAY_HASH_SECRET)
- MoMo (MOMO_PARTNER_CODE, MOMO_ACCESS_KEY, MOMO_SECRET_KEY)
- ZaloPay (ZALOPAY_APP_ID, ZALOPAY_KEY1, ZALOPAY_KEY2)
- **Supported OAuth:** Google, Zalo
- **Storage:** MinIO (MINIO_ACCESS_KEY, MINIO_SECRET_KEY, MINIO_ENDPOINT, MINIO_BUCKET)
- **Infrastructure:** PostgreSQL, Redis, Sentry, Typesense
**Missing .env.example:** ⚠️ MEDIUM - No `.env.example` or `.env.sample` found; developers must infer required vars.
**Severity:** MEDIUM (validation strong, documentation missing)
---
## 9. BUILD, LINT & QUALITY
### ✅ **CURRENT: ESLint + TypeScript with strict checks**
- **ESLint:** Monorepo-level config at root (`eslint.config.mjs`)
- **TypeScript:** `tsc --noEmit` for type-checking without emit
- **Build:** NestJS CLI (`nest build`) outputs to `dist/`
- **Scripts:**
- `npm run lint` - ESLint on `src/`
- `npm run test` - Vitest unit tests
- `npm run test:integration` - Integration suite
- `npm run typecheck` - Type safety only
⚠️ **LOW:** No pre-commit hooks configured (can be added via Husky); CI/CD not shown
**Severity:** LOW (tooling solid, CI/CD unknown)
---
## 10. MONITORING & OBSERVABILITY
### ✅ **GOOD: Sentry + Prometheus + Pino**
- **Error Tracking:** Sentry integration with profiling
- **Metrics:** Prometheus client (HTTP request latency, payments processed, subscriptions active)
- **Logging:** Pino with structured JSON output (pino-pretty for dev)
- **Health Checks:** Terminus module with Prisma + Redis indicators
**MCP Module:** Connected to AI service (configurable base URL)
**Severity:** LOW (solid observability)
---
## 11. CRITICAL FINDINGS SUMMARY
| Issue | Severity | Location | Remediation |
|-------|----------|----------|-------------|
| CSP allows `'unsafe-inline'` scripts | MEDIUM | `main.ts` line 61 | Use nonce-based CSP with hash-based fallback |
| Missing `.env.example` | MEDIUM | Root project | Create `.env.example` with all required vars |
| No e2e tests in CI | MEDIUM | `vitest.integration.config.ts` | Add e2e suite to pipeline |
| JSON.parse without try-catch | LOW | `zalopay.service.ts` | Wrap in error handler (already done, verify) |
| No explicit DELETE cascade rules | LOW | `schema.prisma` | Document orphaned data cleanup |
---
## FINAL SCORE: **8.5/10** ✅
### Strengths:
✅ Exemplary DDD architecture with full layer separation
✅ Comprehensive test coverage (207 test files, 50% LOC ratio)
✅ Strong environment validation & secrets management
✅ Multi-layered security (CSRF, rate-limiting, input sanitization, CSP)
✅ All MVP modules implemented + 6 extras
✅ TypeScript strict mode enforced
✅ Sentry + Prometheus observability
✅ Clean code (no `any`, no console logs)
### Weaknesses:
⚠️ CSP policy review needed (unsafe-inline)
⚠️ Missing `.env.example` documentation
⚠️ No e2e test suite visible
⚠️ CI/CD pipeline not documented
⚠️ No pre-commit hooks
### Recommendations:
1. **High Priority:** Migrate to nonce-based CSP; create `.env.example`
2. **Medium Priority:** Add e2e tests to Vitest config; integrate into CI
3. **Low Priority:** Add Husky pre-commit hooks; document cascade delete rules

- ⚠️ Missing Features: 3 of 5 Sprint items not implemented
---
## 1. SECURITY ISSUES
### Critical Issues
#### 1.1 **Axios SSRF Vulnerability** [CRITICAL]
- **Severity:** CRITICAL
- **Issue:** Axios has a NO_PROXY Hostname Normalization Bypass leading to SSRF
- **Affected Package:** `axios < 1.15.0` (via `typesense > axios`)
- **Path:** `apps__api > typesense > axios`
- **Risk:** Server-side request forgery attacks possible
- **Recommendation:**
- Update typesense dependency to use axios >= 1.15.0
- Pin axios version explicitly in package.json
#### 1.2 **Next.js HTTP Request Deserialization DoS** [HIGH]
- **Severity:** HIGH
- **Issue:** Next.js < 15.0.8 vulnerable to DoS when using insecure React Server Components
- **Affected Package:** `next ^14.2.0` (apps/web/package.json:33)
- **Current Version:** 14.2.0 (vulnerable)
- **Recommendation:**
- Upgrade to Next.js ^15.0.8
- Test compatibility before production deployment
#### 1.3 **Lodash Code Injection & Prototype Pollution** [HIGH]
- **Severity:** HIGH
- **Issues:** Two vulnerabilities in lodash <= 4.17.23
1. Code Injection via `_.template` imports
2. Prototype Pollution via `_.unset` and `_.omit`
- **Affected Path:** `apps__api > @nestjs/config > lodash`
- **Recommendation:**
- Update @nestjs/config to use lodash >= 4.18.0
- Check if lodash can be removed or replaced with native JS
#### 1.4 **path-to-regexp DoS Vulnerabilities** [HIGH]
- **Severity:** HIGH
- **Issues:** Two DoS vulnerabilities (sequential optional groups, regex DoS)
- **Affected Path:** `apps__api > @nestjs/swagger > path-to-regexp`
- **Current Version:** < 8.4.0 (vulnerable)
- **Recommendation:**
- Update @nestjs/swagger to use path-to-regexp >= 8.4.0
### High Priority Issues
#### 1.5 **Next.js Image Optimizer Issues** [MODERATE/HIGH]
- **Issues (3):**
1. DoS via remotePatterns configuration (< 15.5.10)
2. HTTP request smuggling in rewrites (< 15.5.13)
3. Unbounded disk cache growth (< 15.5.14)
- **Current Version:** 14.2.0 (all vulnerable)
- **Recommendation:** Upgrade to Next.js ^15.5.14
### Medium Priority Issues
#### 1.6 **Moderate Vulnerabilities** [MODERATE]
- `@hono/node-server < 1.19.13`: Middleware bypass via repeated slashes
- `@tootallnate/once < 3.0.1`: Incorrect control flow scoping
- Multiple Next.js vulnerabilities affecting image and request handling
**Total Dependencies with Issues:** 6 packages
**Action Required:** 6 high/critical issues MUST be fixed before production
---
## 2. SECURITY BEST PRACTICES ✅
### Positive Findings
**Environment Configuration:**
- `.env` is NOT committed to git (correctly listed in `.gitignore`)
- `.env.example` exists with template values (71 environment variables documented)
- `.env.test` provided for test environment
- No hardcoded secrets found in TypeScript code
**API Security Headers (apps/api/src/main.ts):**
- Helmet.js configured with strong CSP directives
- CORS properly enforced with environment variable validation
- Production CORS requires `CORS_ORIGINS` to be set
- HSTS, X-Frame-Options, Permissions-Policy configured
- Cookie parser for CSRF protection
- Rate limiting trust proxy configuration
**CI/CD Security:**
- E2E tests use separate CI credentials (not production)
- Test database password safely isolated
- JWT secrets in CI are test-only values
### Remaining Gaps
⚠️ **Typesense CORS:**
- Line 50 in `docker-compose.yml`: `TYPESENSE_ENABLE_CORS: 'true'` (acceptable for dev)
- Recommendation: Disable in production or restrict origins
⚠️ **Password Storage:**
- Production secrets use Docker secrets manager (good)
- Grafana admin credentials properly isolated
- Recommendation: Ensure all production secrets use secrets manager
---
## 3. TEST COVERAGE ANALYSIS
### Summary Statistics
- **Total Source Files:** 557 (API: 509, Frontend: 48)
- **Total Test Files:** 166 (API: 166, Frontend: 0)

- **Recommendation**: Add integration tests for critical flows (auth, search, listings)
---
## 8. **Performance** ⚠️ **NEEDS OPTIMIZATION**
**Status**: PARTIAL - Some optimizations in place
### Good:
✅ Dynamic imports for map components (`next/dynamic`)
✅ Suspense boundaries for lazy-loaded content
✅ Image optimization ready (Next.js config allows remote images)
✅ Standalone output mode (better Docker builds)
✅ React Query caching (5min GC time)
### Issues: 🔴
- No explicit `Image` component usage found (using `<img>` tags likely)
- **Impact**: Missing automatic optimization, size reduction
- 30 `'use client'` directives found (some likely unnecessary)
- **Recommendation**: Audit and move data fetching to Server Components
- No font optimization detected
- **Missing**: `next/font` for system fonts or Google Fonts
- No visible route prefetch strategy
- Limited loading states (some pages have `loading.tsx`, others don't)
### Web Vitals:
✅ web-vitals v5.2.0 integrated
✅ Sentry monitoring configured
---
## 9. **Accessibility** 🔴 **NEEDS WORK**
**Status**: POOR - Minimal a11y attributes detected
### Found (28 instances):
- 4 `role="alert"` on error boundaries
- Some `aria-*` attributes in forms
- Limited `alt` text on images
### Missing:
❌ No `aria-label` / `aria-describedby` strategy
❌ No keyboard navigation testing
❌ Limited contrast testing
❌ No ARIA live regions beyond errors
❌ Form labels disconnected from inputs in some cases
### **Recommendation**:
- Run axe DevTools audit
- Add `aria-label` to icon-only buttons
- Ensure all inputs have proper labels
- Test with keyboard navigation
---
## 10. **Build Configuration** ✅
**Status**: GOOD - Properly configured
### Next.js Config (`next.config.js`):
✅ Strict mode enabled
✅ Sentry integration
✅ next-intl plugin
✅ Standalone output
✅ CSP headers configured
✅ Image optimization (remote patterns)
### Tailwind Config:
✅ Dark mode support
✅ CVA integration
✅ Animation plugin
✅ Proper content paths
### TypeScript:
✅ ES2017 target
✅ Bundler module resolution
✅ Path aliases (`@/*`)
✅ Incremental builds enabled
---
## 11. **Missing Pages vs MVP Blueprint** 🔴
**MVP Pages (11 planned)**:
1. ✅ Landing (`/`)
2. ✅ Search Results (`/search`)
3. ✅ Listing Detail (`/listings/[id]`)
4. ✅ Login (`/login`)
5. ✅ Register (`/register`)
6. ✅ Dashboard (`/dashboard`)
7. ✅ Admin Panel (`/admin`)
8. ✅ Analytics (`/analytics`)
9. ⚠️ **Pricing** - **MISSING**

# GoodGo Platform AI - Test Coverage Audit Report
**Date:** April 10, 2026
**Repository:** /Users/velikho/Desktop/WORKING/goodgo-platform-ai/apps/api/src/modules/
---
## EXECUTIVE SUMMARY
This audit analyzes test coverage across three critical modules in the GoodGo Platform AI backend:
| Module | Source Files | Test Files | Coverage |
|--------|-------------|-----------|----------|
| **Listings** | 42 | 13 | 31% |
| **Auth** | 56 | 21 | 38% |
| **Search** | 22 | 10 | 45% |
| **TOTAL** | **120** | **44** | **37%** |
**Key Finding:** While test files exist for major handlers and domain entities, many critical infrastructure services, value objects, repositories, and presentation layer components lack test coverage.

- `presentation/guards/roles.guard.spec.ts`
- `infrastructure/repositories/prisma-user.repository.spec.ts`
- `infrastructure/strategies/jwt.strategy.spec.ts`
- `infrastructure/strategies/local.strategy.spec.ts`
2. **Create 4 critical tests for LISTINGS module:**
- `infrastructure/repositories/prisma-listing.repository.spec.ts`
- `infrastructure/services/prisma-duplicate-detector.spec.ts`
- `infrastructure/services/prisma-price-validator.spec.ts`
- `domain/services/moderation.service.spec.ts`
### Short Term (Week 2-3)
3. **Infrastructure Repository Tests:**
- All Prisma repository implementations
- Search repository implementations
4. **Integration/Event Tests:**
- Event handler tests for all domain events
- Event publishing verification
5. **Presentation Layer Tests:**
- All controllers
- All guards and decorators
- DTO validation tests
### Medium Term (Week 4+)
6. **End-to-End Tests:**
- Full user flow tests (registration → authentication → data access)
- Listing lifecycle tests (creation → moderation → publishing)
- Search feature tests (indexing → retrieval)

## Conclusion
The GoodGo Platform AI monorepo has a **37% test coverage** across the three critical modules examined, with significant gaps in:
- **Security-critical guards and strategies (AUTH)**
- **Infrastructure data access layers (all modules)**
- **Presentation layer controllers and DTOs (all modules)**
- **Domain event models (LISTINGS & AUTH)**
The **Search module** shows the strongest test coverage at **45%**, with most handlers and services tested. The **Listings and Auth modules** need immediate attention to the security and business logic components identified in Tier 1 recommendations.

## 🔴 CRITICAL - Must Test First (11 files)
### AUTH Module - Security Critical (4 files)
```
1. presentation/guards/jwt-auth.guard.ts
└─ Why: Token validation security
└─ Test: Valid tokens, expired, invalid signatures
2. presentation/guards/roles.guard.ts
└─ Why: Authorization enforcement
└─ Test: Admin access, user access, denied access
3. infrastructure/repositories/prisma-user.repository.ts
└─ Why: Primary user data access
└─ Test: CRUD operations, user lookup queries
4. infrastructure/strategies/jwt.strategy.ts
└─ Why: JWT authentication
└─ Test: Token validation, user extraction
```
### LISTINGS Module - Business Logic Critical (4 files)
```
5. infrastructure/services/prisma-duplicate-detector.ts
└─ Why: Core duplicate detection
└─ Test: Database queries, similarity logic
6. infrastructure/services/prisma-price-validator.ts
└─ Why: Price validation logic
└─ Test: Price ranges, validation rules
7. infrastructure/repositories/prisma-listing.repository.ts
└─ Why: Primary listing data access
└─ Test: CRUD operations, complex queries
8. domain/services/moderation.service.ts
└─ Why: Moderation business rules
└─ Test: Approval/rejection logic, scoring
```
### SEARCH Module - Integration Critical (2 files)
```
9. infrastructure/services/typesense-client.service.ts
└─ Why: Search engine integration
└─ Test: Client init, connection, errors

## 🧪 Test Type Guidelines
### Unit Tests (50 minutes per file avg)
**For:** Services, repositories, value objects, entities
```typescript
// Test structure
describe('ServiceName', () => {
let service: ServiceName;
let mockDependency: Mock;
beforeEach(() => {
mockDependency = mock();
service = new ServiceName(mockDependency);
});
it('should handle success case', () => {});
it('should handle error case', () => {});
});
```
### Integration Tests (60 minutes per file avg)
**For:** Repositories, event handlers, strategies
```typescript
// Test structure - usually with database/real service
describe('RepositoryName', () => {
let repository: RepositoryName;
let prisma: PrismaClient; // or real client
beforeEach(async () => {
await setupTestDatabase();
repository = new RepositoryName(prisma);
});
afterEach(async () => {
await cleanupTestDatabase();
});
});
```
### Guard/Decorator Tests (30 minutes per file avg)
**For:** Guards, decorators, middleware
```typescript
// Test structure
describe('GuardName', () => {
let guard: GuardName;
let mockExecutionContext: Mock;
it('should allow authorized requests', () => {});
it('should deny unauthorized requests', () => {});
});
```
### Controller Tests (40 minutes per file avg)
**For:** REST controllers
```typescript
// Test structure
describe('ControllerName', () => {
let controller: ControllerName;
let mockService: Mock;
it('should handle POST request', () => {});
it('should return 400 for invalid input', () => {});
});
```
### DTO Tests (20 minutes per file avg)
**For:** Data validation objects
```typescript
// Test structure - focus on validation
describe('DtoName', () => {
it('should validate correct data', () => {});
it('should reject invalid email', () => {});
it('should reject short password', () => {});
});
```
