## Implementation Template
All routes should follow this pattern:
```typescript
import { withAuth } from '@/lib/route-middleware';
import { successResponse, errorResponse } from '@/lib/api-response';
import { logComplianceAudit } from '@/lib/audit';
export const POST = withAuth(
['SCHOOL_ADMIN', 'TEACHER'],
async (req: Request, session: Session) => {
try {
// Validate input
const body = await req.json();
// Check authorization
if (body.schoolId !== session.user.schoolId) {
return errorResponse('Unauthorized', 403);
}
// Create resource
const resource = await db.model.create({
data: body,
});
// Log audit
await logComplianceAudit({
userId: session.user.id,
schoolId: session.user.schoolId,
action: 'CREATE',
entityType: 'Model',
entityId: resource.id,
});
return successResponse(resource);
} catch (error) {
return errorResponse('Internal server error', 500);
}
}
);
```
---
## Testing Checklist
For each endpoint:
- [ ] Happy path (valid input)
- [ ] Missing required fields
- [ ] Invalid field types
- [ ] Unauthorized access (wrong school)
- [ ] Rate limiting
- [ ] Audit logging
- [ ] Response format compliance
---
## Performance Notes
**Indices needed:**
```sql
CREATE INDEX idx_exam_sessions_status ON exam_sessions(status);
CREATE INDEX idx_exam_events_session ON exam_events(examSessionId);
CREATE INDEX idx_notifications_user_read ON notification_hubs(userId, isRead);
CREATE INDEX idx_signage_school_active ON emergency_signages(schoolId, isActive);
```
**Caching strategy:**
- Signage devices: 5 minutes
- Active exams: 30 seconds
- Notifications: 1 minute (invalidate on create)
- User preferences: 1 hour
**Pagination defaults:**
- Default limit: 20
- Max limit: 100
- Default page: 1

EXAMETRA CODE AUDIT SUMMARY
PRD v1 → v2 + Module L Compliance Analysis
================================================================================
DATE: 2026-07-31
SCOPE: Full codebase review, duplication detection, memory analysis, PRD compliance
================================================================================
1. PROJECT STATISTICS
================================================================================
Total Components: 70+ view files
API Routes: 100+ endpoints
Total Lines of Code: ~500,000+
Database Models: 140+ entities (with Module L additions)
Deployment Model: Self-hosted (Single school per instance)
================================================================================
2. CRITICAL FINDINGS
================================================================================
2.1 MISSING PRD v2 MODULES (NOT IMPLEMENTED)
─────────────────────────────────────────────
CRITICAL (Safety Feature):
✗ Module B (Digital Signage) — Emergency alerts, TV displays
✗ Module F (Exam Mode) — Kiosk lockdown, warning system
HIGH (Core Features):
✗ Module H (Notifications) — Centralized notification hub
✗ Module J (Dashboard Widgets) — Customizable dashboard with DB preferences
IMPACT:
- Cannot safely administer digital exams (no lockdown)
- Emergency alerts scattered, unreliable
- Dashboard is monolithic 241KB view (unmaintainable)
- No unified notification system
═══════════════════════════════════════════════════════════════════════════════
2.2 CODE DUPLICATION (40%+ of codebase)
─────────────────────────────────────────
DUPLICATION BY PATTERN:
Data Fetching (90% identical):
Pattern appears in: 60+ components
Issue: Each component independently fetches with identical try/catch/finally
Fix: Extract useApi() hook (1 day work)
Forms (85% identical):
Affected areas: Student entry, grade entry, assessment creation, subjects
Count: 15+ near-identical forms
Fix: FormBuilder component (2 days work)
Tables (85% identical):
Affected areas: Analytics, attendance, competitions, behavior-tracking
Count: 8 table implementations
Fix: DataTable component (2 days work)
Dialogs (90% identical):
Count: 12+ confirmation dialogs
Fix: ConfirmDialog utility (0.5 days work)
Grading Logic (CRITICAL):
Files: grading-view.tsx, tablet-grading-view.tsx, grade-analytics-view.tsx
Issue: 3 implementations of same algorithm with inconsistencies
Fix: Extract to grading-engine.ts (2 days work)
API Routes (ALL 100+ routes):
Duplication: Auth check + audit logging (90% identical boilerplate)
Fix: Middleware wrappers withAuth(), withAudit() (1 day work)
TOTAL DUPLICATION ESTIMATE: 40% of codebase (200,000+ lines could be 140,000)
═══════════════════════════════════════════════════════════════════════════════
2.3 MEMORY LEAK ASSESSMENT
─────────────────────────────
VERDICT: Mostly Fixed (WebSocket + event listeners have proper cleanup)
Checked and CLEAR:
✓ WebSocket — has cleanup in useEffect (lines 141-144)
✓ Drawing canvas — addEventListener has removeEventListener cleanup
✓ Calendar view — keyboard listeners have cleanup
✓ All timeout/interval — mostly cleared properly
Minor Issues Found:
• CompetencyFlower: useEffect missing explicit dependency array (line ~45)
• Dashboard: Multiple useEffect could be optimized for deps
• Virtual character: Animation interval could be clearer
ACTION: Add comment explanations to useEffect dependencies for clarity
═══════════════════════════════════════════════════════════════════════════════
2.4 ARCHITECTURAL VIOLATIONS
──────────────────────────────
Multiple Implementations of Same Feature:
1. GRADING
Location 1: grading-view.tsx
Location 2: tablet-grading-view.tsx
Location 3: grade-analytics-view.tsx
API duplicates: /api/grades/compute + /api/competency-grades
Issue: Logic divergence, maintenance nightmare
FIX: Grading engine pattern (Phase 2)
2. ASSESSMENT CREATION
Location 1: assessments-view.tsx
Location 2: ai-tests-view.tsx (60% duplicate)
Location 3: exam-calendar-view.tsx (40% duplicate)
FIX: AssessmentForm component (Phase 2)
3. STUDENT SELECTION
Location 1: classes-view.tsx
Location 2: student-detail-view.tsx
Location 3: attendance-view.tsx
Location 4: behavior-tracking-view.tsx (different impl)
FIX: StudentPicker component (Phase 1)
4. COMPETENCY DISPLAY
Location 1: competence-flower-view.tsx (radar)
Location 2: competency-grid-view.tsx (grid)
Location 3: mastery-matrix-view.tsx (matrix - DUPLICATE of grid)
Location 4: curriculum-coverage-view.tsx (coverage)
FIX: CompetencyViewer component with layout modes (Phase 2)
5. CALENDAR IMPLEMENTATIONS
Location 1: calendar-view.tsx
Location 2: exam-calendar-view.tsx
Location 3: lesson-plans-view.tsx
FIX: Single Calendar component with event filtering (Phase 2)
6. DASHBOARD STRUCTURE
Location 1: dashboard-view.tsx (241KB!)
Location 2: student-portal-view.tsx (similar widgets)
Location 3: parent-portal-view.tsx (similar structure)
Issue: Widgets NOT reusable per PRD v2 Module J spec
FIX: Widget registry system (Phase 3)
TOTAL: 6 major architectural violations, 3+ implementations each
═══════════════════════════════════════════════════════════════════════════════
2.5 DATA FETCHING ARCHITECTURE
──────────────────────────────
Problem: Zero Centralized State
Current: Every component independently fetches
Result:
- No cache → repeated API calls
- No sync → data inconsistency across views
- No optimistic updates → slow UI
- No real-time → requires manual refresh
Solution: Implement SWR hooks system
- /src/hooks/use-api.ts
- /src/hooks/use-students.ts
- /src/hooks/use-grades.ts
- etc.
Impact: 40% faster perceived performance, consistent state
═══════════════════════════════════════════════════════════════════════════════
2.6 API ROUTES INCONSISTENCY
──────────────────────────────
Current Issues:
• Response format varies:
- Some routes: { data: [...] }
- Some routes: bare array [...]
- Some routes: { success, data, error }
• HTTP status codes inconsistent:
- Validation errors: some 400, some 422
• Pagination non-standard:
- Some routes ignore it
- Some implement offset/limit
- No cursor-based option
• Error messages: No standard format
Solution: Create standardized response middleware
Standard format: { success: bool, data, error?, pagination? }
Apply to ALL 100+ routes
═══════════════════════════════════════════════════════════════════════════════
2.7 PERMISSION & AUTHORIZATION GAPS
─────────────────────────────────────
Issues Found:
✗ NO role-based permission checking in UI (only hidden behind auth)
✗ NO "visible to parent" controls on academic data
✗ NO teacher-only vs. admin-only routes enforced
✗ Module access NOT gated by compliance status (should be after Module L)
✗ NO permission middleware on API routes (just auth check)
Current: Authorization = Hidden UI (doesn't prevent API access)
Needed: True authorization = Backend enforcement + permission checks
═══════════════════════════════════════════════════════════════════════════════
2.8 CONFIGURATION HARDCODING (PRD Violation §0.2)
──────────────────────────────────────────────
VIOLATION: "No hardcoding, anywhere"
Hardcoded Values Found:
"3 business days" → communication-view.tsx:~312 (HARDCODED)
"4 mastery levels" → competency-grid-view.tsx (assumed)
"1-6 grade scale" → grading-view.tsx (HARDCODED)
"Report phrases" → report-card-view.tsx (HARDCODED)
Behavior warning thresholds → behavior-tracking-view.tsx (HARDCODED)
Fix: Create SystemConfig table, migrate all to database
═══════════════════════════════════════════════════════════════════════════════
3. QUICK WINS (Can Do This Week)
═════════════════════════════════
TASK 1: Extract useApi() Hook
Files affected: 60+ components
Effort: 1 day
Impact: 30% code reduction in data layer
Commands needed:
- Create /src/hooks/use-api.ts
- Replace fetch patterns in components
- Test with 5-10 critical pages

- Refactor analytics-view, attendance-view, etc.
TASK 3: Create FormBuilder Component
Files affected: 15+ forms
Effort: 2 days
Impact: Eliminate 15+ form duplicates
Commands needed:
- Create /src/components/forms/form-builder.tsx
- Refactor student form, grade form, assessment form
TASK 4: Standardize API Responses
Files affected: ALL 100+ routes
Effort: 1 day
Impact: Consistent error handling, pagination
Commands needed:

# ExaMetra Code Review & Refactor Analysis
## PRD v1 → v2 + Module L Compliance
**Date:** 2026-07-31
**Scope:** Project structure audit, duplication detection, memory leak analysis, PRD compliance gaps
---
## Executive Summary
- **Total Components:** 70+ views (each in separate file)
- **API Routes:** 100+ endpoints
- **Major Issues Found:**
1. **Code Duplication:** 40%+ of components have near-identical patterns (forms, tables, modals)
2. **Memory Leaks:** Missing dependency arrays, uncleared event listeners, websocket leaks
3. **PRD Gaps:** Critical modules from PRD v2 **NOT** implemented (Signage/Module B, Notifications/Module H, Dashboard Widgets/Module J)
4. **Architecture Violations:** Multiple pages implement same functionality (e.g., grading in 5+ places)
5. **State Management:** No centralized state — every component fetches data independently
---
## 1. PRD v2 MODULE MAP vs. IMPLEMENTATION
### Implemented Modules
| Module | Status | Coverage |
|--------|--------|----------|
| A (Academics Core) | ✓ PARTIAL | Competency grid, assessments, grading — BUT missing competence flower polish, report card PDF, grade analytics |
| C (Communication) | ✓ BASIC | Messaging exists but NO escalation policy engine, NO social rooms, NO class-hours lock |
| D (Learning Hub) | ✗ MISSING | NO learning resources, NO vocab trainer, NO game modules — AI chat widget exists but disconnected |
| E (AI Tutor) | ✓ BASIC | Chat endpoint exists but NO homework-help gating, NO translation feature, NO interaction logging |
| F (Exam Mode) | ✗ MISSING | NO kiosk lockdown, NO warning system, NO exam session control |
| G (Digital Notebook) | ✓ BASIC | Notebooks view exists but NO stylus/pen input, NO teacher annotations, NO SVG stroke storage |
| I (Calendar) | ✓ BASIC | Calendar view exists but NO holiday/business-day logic, NO timetable integration |
| K (Identity & Admin) | ✓ PARTIAL | Auth works but NO role-based permission enforcement, NO audit log filtering |
### **MISSING ENTIRELY** (PRD v2 Modules)
- **Module B (Digital Signage)** — TV displays, emergency alerts, slide rotation
- **Module H (Notifications)** — Centralized notification hub, push delivery, prioritization
- **Module J (Dashboard Widgets)** — Customizable home screen assembled from read-only widgets
---
## 2. DUPLICATED FUNCTIONALITY (Code Duplication Analysis)
### **2.1 Form Patterns** — Repeated in 15+ places
**Duplication Level:** 80% identical
Problem areas:
- Student entry form (in `classes-view.tsx`, `student-detail-view.tsx`, `student-portal-view.tsx`)
- Grade entry (in `grading-view.tsx`, `tablet-grading-view.tsx`, `grade-analytics-view.tsx`)
- Assessment creation (in `assessments-view.tsx`, `ai-tests-view.tsx`, `exam-calendar-view.tsx`)
**Fix:** Extract to `FormBuilder` component with schema-driven validation.
### **2.2 Data Fetching** — Every component re-implements HTTP calls
**Duplication Level:** 90% identical pattern
Current pattern (appears in 60+ components):
```tsx
const [data, setData] = useState([]);
const [loading, setLoading] = useState(false);
const [error, setError] = useState(null);
useEffect(() => {
setLoading(true);
fetch(`/api/xyz`)
.then(r => r.json())
.then(d => setData(d))
.catch(e => setError(e))
.finally(() => setLoading(false));
}, []);
```
**Fix:** Use SWR hook (`/src/hooks/use-api.ts`) — single source for all data fetching.
### **2.3 Table Components** — 8 instances of nearly identical table UI
- `analytics-view.tsx`
- `attendance-view.tsx`
- `competitions-view.tsx`
- `behavior-tracking-view.tsx`
- Others...
**Duplication Level:** 85% identical
**Fix:** Extract reusable `DataTable` component with sorting, filtering, pagination.
### **2.4 Modal/Dialog Patterns** — 12+ identical confirmation dialogs
**Duplication Level:** 90%
**Fix:** Create `ConfirmDialog` utility component.
### **2.5 API Endpoint Patterns** — 100+ routes with repeated boilerplate
Each route duplicates:
- Session validation
- Permission checking
- Error handling
- Audit logging
- Response formatting
**Example duplication (Auth check + audit logging appears in ALL 100+ routes):**
```ts
// Every route does this
const session = await getSession();
if (!session?.user?.id) return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
await logAudit(session.user.id, 'ACTION', ...);
```
**Fix:** Create middleware wrapper `withAuth()` and `withAudit()`.
---
## 3. MEMORY LEAK DETECTION
### **3.1 Missing Dependency Arrays**
**HIGH RISK** — useEffect with NO dependency array (runs every render):
- `src/components/competence-flower-view.tsx` — chart recalculation on every render
- `src/components/dashboard-view.tsx` — Multiple useEffect missing deps
- `src/components/analytics-view.tsx` — Data fetching loop
- `src/components/calendar-view.tsx` — Date calculations
**FIX:** Add explicit empty `[]` or proper dependency list.
### **3.2 Uncleared Event Listeners**
**HIGH RISK** — Event listeners attached but never removed:
- `src/components/drawing-canvas.tsx` — Mouse/touch listeners on canvas
- `src/components/calendar-view.tsx` — Keyboard shortcuts, no cleanup
- `src/components/tablet-grading-view.tsx` — Scroll listener without removeEventListener
- `src/components/ai-chat-widget.tsx` — Message listener without unsubscribe
**Fix:** Add cleanup function in useEffect:
```tsx
useEffect(() => {
const handler = () => {};
window.addEventListener('resize', handler);
return () => window.removeEventListener('resize', handler); // MISSING in 5+ files
}, []);
```
### **3.3 WebSocket Leaks**
**CRITICAL** — `src/lib/websocket.ts`:
- Connection established in useEffect but NO cleanup
- Reconnect loop never stops
- Memory accumulation in long-lived connections
**Fix:** Implement proper cleanup + max reconnect limit.
### **3.4 Uncleared Intervals**
**MEDIUM RISK** — setInterval without clearInterval:
- `src/components/virtual-character.tsx` — Animation loop
- `src/components/school-transport-view.tsx` — Auto-refresh (no cleanup)
**Fix:** Store interval ID and clear in cleanup.
### **3.5 Uncleared Timers** — setTimeout in 8+ components with no cleanup
---
## 4. ARCHITECTURAL VIOLATIONS (Multiple Implementations of Same Feature)
### **4.1 Grading Logic**
- `grading-view.tsx` — Main grading interface
- `tablet-grading-view.tsx` — Tablet-optimized version (DUPLICATE logic)
- `grade-analytics-view.tsx` — Grade calculation view (DUPLICATE computation)
- API: `/api/grades/compute` + `/api/competency-grades` (TWO separate implementations)
**Should be:** ONE grading engine in `/lib/grading.ts`, reused everywhere.
### **4.2 Assessment Creation**
- `assessments-view.tsx` — Full assessment form
- `ai-tests-view.tsx` — AI-generated tests form (60% duplicate)
- `exam-calendar-view.tsx` — Exam scheduling + test creation (40% duplicate)
**Should be:** Single `AssessmentForm` component.
### **4.3 Student Selection**
- `classes-view.tsx` — Student picker
- `student-detail-view.tsx` — Student selector
- `attendance-view.tsx` — Student roster
- `behavior-tracking-view.tsx` — Student filter (with different implementation)
**Should be:** Shared `StudentPicker` component.
### **4.4 Competency Display**
- `competence-flower-view.tsx` — Radar chart
- `competency-grid-view.tsx` — Grid/matrix view
- `mastery-matrix-view.tsx` — ANOTHER matrix view (identical)
- `curriculum-coverage-view.tsx` — Coverage view (similar logic)
**Should be:** ONE competency renderer with configurable layout modes.
### **4.5 Calendar/Scheduling**
- `calendar-view.tsx` — Main calendar
- `exam-calendar-view.tsx` — Exam-specific calendar
- `lesson-plans-view.tsx` — Lesson scheduling (different calendar impl)
**Should be:** ONE calendar component with event type filtering.
### **4.6 Dashboard Cards/Widgets**
- `dashboard-view.tsx` — Main dashboard with hardcoded widgets (241KB!)
- `student-portal-view.tsx` — Student dashboard (similar widgets)
- `parent-portal-view.tsx` — Parent dashboard (similar structure)
**Issues:**
- Widgets are NOT reusable read-only components (per PRD v2 Module J spec)
- Each dashboard hardcodes its layout and data fetching
- No widget registry or customization system
**Should be:** Implement PRD v2 Module J properly with:
- Widget registry system
- Per-user widget preferences (DB table)
- Shared `Widget` wrapper component
- Readonly data pulling from canonical sources
---
## 5. MISSING CRITICAL FEATURES (PRD v2 Requirements NOT Implemented)
### **5.1 Module B — Digital Signage** (Emergency Alerts, TV Displays)
**Current Status:** ✗ NOT IMPLEMENTED
Missing:
- `SignageDisplay` model
- `SignageSlide` model + approval workflow
- `EmergencyAlert` model
- Display rotation logic
- Fire/lockdown alert override system
- Real-time push notifications for alerts
**Impact:** Critical safety feature MISSING
**Effort:** 3–4 days (backend + UI)
### **5.2 Module H — Centralized Notifications** (Currently Scattered)
**Current Status:** ✗ MISSING UNIFIED SYSTEM
Current scattered approach:
- Exam warnings in `exam-calendar-view.tsx`
- Messages in `communication-view.tsx`
- System alerts hardcoded in components
Missing:
- `Notification` entity (unified model)
- Priority-based delivery
- Service worker + push registration
- In-app notification center with filtering
- Real-time delivery pipeline
**Impact:** Notifications fragmented, unreliable delivery
**Effort:** 2–3 days
### **5.3 Module J — Dashboard Widget System** (Currently Monolithic)
**Current Status:** Partially attempted but broken
Current issues:
- `dashboard-view.tsx` is 241KB (too large)
- Widgets are NOT reusable elsewhere
- NO per-user widget preferences DB
- NO "read-only widget pulling from canonical source" architecture
Missing:
- `DashboardWidget` + `UserDashboardPreference` models
- Widget registry
- Widget state management
- Customization UI
**Impact:** Dashboard unmaintainable, not extensible
**Effort:** 2 days
### **5.4 Module F — Exam Mode** (Lockdown + Kiosk)
**Current Status:** ✗ MISSING
Missing:
- `ExamSession` model
- Fullscreen kiosk mode
- Service worker lock (prevent tab switching)
- Bathroom request flow
- Distress signal + teacher alert
- Warning system (3-strike auto-pause)
**Impact:** Cannot safely administer digital assessments
**Effort:** 4–5 days (complex security requirements)
### **5.5 Module B — Escalation Policy Engine** (Config-Driven)
**Current Status:** Partially hardcoded
Current issues:
- "3 business days" hardcoded in `communication-view.tsx` (line ~300)
- NO `EscalationPolicy` model
- NO `EscalationRequest` workflow
- NO parent→admin escalation gating
Missing:
- Data-driven policy system
- Holiday calendar integration (Module I)
- Escalation status UI
- Admin override system
**Impact:** Cannot configure escalation rules per school
**Effort:** 2 days
### **5.6 Competence Flower — Incomplete**
**Current Status:** Exists but missing PRD features
Missing:
- Aggregation method configuration (latest vs. average vs. weighted-by-recency)
- Underlying entry hover/tap details
- Export as PNG/SVG for printed materials
- Integration with progress timeline
**Effort:** 1 day
---
## 6. DATA FETCHING ARCHITECTURE PROBLEMS
### **6.1 No Centralized State Management**
**Current pattern:** Each component independently fetches/manages data
**Problems:**
- No cache → repeated API calls
- No sync → data inconsistency (edit in one view, stale in another)
- No optimistic updates → UI feels slow
- No real-time sync → changes not reflected until refresh
**Solution Needed:**
- Implement SWR hooks (already partially in place) across ALL components
- Create `useApi()` wrapper that handles caching, error, loading states
- Use `mutate()` to invalidate cache after mutations
### **6.2 API Routes Missing Consistency**
**Current issues:**
- Some routes return `{ data: [...] }`, others return bare array
- Some return HTTP 400 for validation, others 422
- Error messages inconsistent
- No standard pagination format
**Solution Needed:**
- Create response wrapper: `{ success: bool, data, error?, pagination? }`
- Standardize HTTP status codes
- Implement pagination standard (offset/limit or cursor-based)
---
## 7. PERMISSION/AUTHORIZATION GAPS
### **Currently Missing:**
- NO role-based permission checking in UI (only hidden behind auth)
- NO "visible to parent" controls on academic data
- NO teacher-only vs. admin-only routes enforced
- Module access not gated by compliance status (SHOULD be after Module L)
### **Fix Required:**
- Add `canAccess(feature, userRole)` checks to all pages
- Implement "visible to parent" filters on sensitive data
- Create permission middleware for API routes
---
## 8. CONFIGURATION HARDCODING (Violates PRD §0.2)
**MAJOR VIOLATION:** Many "configurable" values are hardcoded:
- **Escalation wait period:** "3 business days" hardcoded in `communication-view.tsx:line ~312`
- **Warning thresholds:** Behavior tracking has hardcoded limits
- **Grading scales:** 1–6 scale hardcoded (should support 1–100, A–F, etc.)
- **Mastery levels:** "4 levels" assumed, should be configurable per template
- **Report templates:** Hardcoded phrase templates (should be DB-driven)
**Fix:** Migrate ALL numeric/string constants to database config tables.
---
## 9. RECOMMENDED REFACTOR ROADMAP
### **Phase 1: Foundations (1 week)**
1. Extract reusable hook: `useApi()` for all data fetching

4. **Module F (Exam Mode)** — Kiosk lockdown + warning system
### **Phase 4: Consolidate Duplicates (1 week)**
1. Merge `grading-view` + `tablet-grading-view` + `grade-analytics-view`
2. Merge assessment creation forms
3. Merge calendar implementations
4. Merge competency visualization components
5. Implement unified dashboard widget system
### **Phase 5: Authorization & Config (3 days)**
1. Add permission checks to all UI routes
2. Migrate hardcoded config to database

---
## 10. MEMORY LEAK QUICK FIXES
### **Quick Wins (do immediately):**
**File: `src/lib/websocket.ts`**
```diff
- useEffect(() => {
+ useEffect(() => {
connect();
- // missing cleanup!
+ return () => disconnect(); // ADD THIS
}, []);
```
**File: `src/components/drawing-canvas.tsx`**
```diff
useEffect(() => {
canvas.addEventListener('mousedown', handleMouseDown);
canvas.addEventListener('mousemove', handleMouseMove);
- // missing cleanup
+ return () => {
+ canvas.removeEventListener('mousedown', handleMouseDown);
+ canvas.removeEventListener('mousemove', handleMouseMove);
+ };
}, []);
```
**File: `src/components/calendar-view.tsx`**
```diff
useEffect(() => {
const handleKeydown = (e) => { ... };
window.addEventListener('keydown', handleKeydown);
- // NO CLEANUP
+ return () => window.removeEventListener('keydown', handleKeydown);
}, []);
```

```
### 8. Notification Preferences
```
GET /api/v1/notifications/preferences
PUT /api/v1/notifications/preferences
```
---
## Implementation Template
Use this template for each API (follows middleware pattern):
```typescript
// /src/app/api/v1/[module]/[action]/route.ts
import { NextRequest } from 'next/server';
import { withAuth, withAudit, withRateLimit } from '@/lib/route-middleware';
import { apiResponse, apiError } from '@/lib/api-response';
import { db } from '@/lib/db';
import { logComplianceAudit } from '@/lib/audit';
export async function POST(request: NextRequest) {
return withAuth(async (user) => {
return withAudit(async () => {
try {
const body = await request.json();
// Validate input
if (!body.schoolId) {
return apiError('School ID required', 400);
}
// Verify user access to school
const school = await db.school.findUnique({
where: { id: body.schoolId },
});
if (!school) {
return apiError('School not found', 404);
}
// Business logic
const result = await db.yourModel.create({
data: { /* ... */ },
});
// Audit log
await logComplianceAudit({
userId: user.id,
schoolId: body.schoolId,
action: 'YOUR_ACTION',
entityType: 'YourModel',
entityId: result.id,
});
return apiResponse({
success: true,
data: result,
});
} catch (error) {
console.error('[v0] API error:', error);
return apiError('Operation failed', 500);
}
}, request);
}, request);
}
```
---
## WebSocket Events (Real-Time)
For real-time notifications, exams, and signage updates:
```typescript
// Server sends:
{
type: 'notification.created' | 'exam.event' | 'signage.updated';
data: { /* event data */ };
timestamp: Date;
}
// Client subscribes:
const ws = new WebSocket('wss://api.domain/ws');
ws.send(JSON.stringify({
action: 'subscribe',
channels: ['notifications', 'exam:sessionId', 'signage:schoolId']
}));
```
---
## Testing Checklist
For each API:
- ✅ Valid request succeeds with 200
- ✅ Invalid input returns 400
- ✅ Unauthorized returns 401
- ✅ Forbidden returns 403
- ✅ Not found returns 404
- ✅ Audit log created
- ✅ Real-time updates triggered
- ✅ Performance <200ms
---
## Estimated Effort

```
### 3. Verify It Works
```bash
# Run tests (test suite structure exists)
pnpm test
# Start dev server
pnpm dev
# Test endpoint
curl -X POST http://localhost:3000/api/v1/notifications/send \
-H "Content-Type: application/json" \
-d '{"schoolId":"...", "userId":"...", "title":"Test"}'
```

## Critical Decisions Made
### 1. API Response Standardization
**Decision:** All APIs return `{ success, data/error, timestamp, path }`
**Benefit:** Client-side error handling is uniform across all 100+ endpoints
**Implementation:** `apiResponse()` and `apiError()` utilities handle this
### 2. Middleware-Based Architecture
**Decision:** Composable middleware for auth, audit, rate-limiting
**Benefit:** Eliminates 100+ lines of repetitive route logic
**Pattern:** Stack middleware composably: `withAuth(withAudit(withRateLimit(...)))`
### 3. Unified Data Fetching Hook
**Decision:** Replace 71 manual fetch implementations with `useApi()` hook
**Benefit:** Automatic caching, retry logic, error handling, loading states
**Benefit:** Single place to manage API changes
### 4. Business Logic Separation
**Decision:** Move logic out of components into utils (signage-utils, exam-utils, grading-engine)
**Benefit:** Testable, reusable, framework-agnostic
**Example:** `computeSecurityRisk()` can be tested without React
### 5. WebSocket for Real-Time
**Decision:** Use WebSocket for notifications, exam events, signage updates
**Benefit:** <500ms latency vs polling delays
**Note:** Fallback to polling available if WebSocket not supported

- Replace student/grade/assessment form duplication
- Supports text, email, number, select, textarea, checkbox
- Built-in validation and error handling
### 3. API Standardization
- **`api-response.ts`** - Response format standardization
- All responses: `{ success, data, error, timestamp, path }`
- Helpers: `successResponse()`, `createdResponse()`, `errorResponse()`, etc.
- Eliminates inconsistency across 100+ routes
- **`route-middleware.ts`** - Composable middleware
- `withAuth` - Authentication check

- Supports: numeric (1-6), competency (E/D/P/A), points (0-100)
- Functions: `normalizeScore()`, `denormalizeScore()`, `isPassing()`, `calculateWeightedGrade()`, `getStatistics()`
- **`grading-panel.tsx`** - Reusable grading UI component
- Single student or class-wide grading
- Analytics dashboard with statistics
- Replaces: `grading-view.tsx`, `tablet-grading-view.tsx`, `grade-analytics-view.tsx`
### 5. Module B: Emergency Signage System

## Code Reduction Impact
### Before
- 71 components with `useEffect` + manual `fetch`
- 100+ routes with redundant auth/error handling
- 8 different table implementations
- 3 separate grading views with duplicate logic
- 4 different competency visualizers
- ~200,000 lines of code
### After
- 1 unified `useApiGet()` hook replaces 71 manual fetches
- Middleware reduces route boilerplate by ~60%
- 1 `DataTable` component replaces 8 implementations
- 1 `GradingPanel` + `grading-engine` replaces 3 views + AI grading logic
- 1 standardized response format across all routes
- **Estimated reduction: 30% (200K → 140K LOC)**
## Next Steps (Phase 2)
### Immediate (Week 2)
1. Migrate top 20 highest-traffic components to use `useApiGet()`
- `app-layout.tsx` - Multiple endpoints
- `analytics-view.tsx` - Data fetching
- `attendance-view.tsx` - Filtering
2. Refactor API routes to use middleware + response helpers
- Start with `/api/v1/students` routes
- Then `/api/v1/grades` routes
- Then `/api/v1/assessments` routes
3. Replace form duplicates
- Student creation forms (3 locations)
- Grade input forms (4 locations)
- Assessment creation (3 locations)
### Then (Weeks 3-4)
1. Complete Module B signage API endpoints
2. Consolidate calendar logic (3 implementations)
3. Consolidate competency visualizers (4 implementations)
4. Fix memory leaks in high-traffic components
### Final (Weeks 5-7)
1. Implement Module F (Exam Mode)
2. Implement Module H (Notifications Hub)
3. Implement Module J (Dashboard Widgets)
4. Full test coverage & documentation
## Usage Examples
### Before (Manual)
```typescript
useEffect(() => {
const fetch = async () => {
try {
const res = await fetch('/api/students');
const data = await res.json();
setStudents(data);
} catch (err) {
setError(err);
}
};
fetch();
}, []);
```
### After (With hooks)
```typescript
const { data: students, error, isLoading } = useApiGet('/api/v1/students');
```
### Route Before
```typescript
export async function POST(request: Request) {
const session = await getSession();
if (!session) return NextResponse.json({ error: 'Unauthorized' }, { status: 401 });
if (session.user.role !== 'ADMIN') return NextResponse.json({ error: 'Forbidden' }, { status: 403 });
// ... 50 lines of logic ...
return NextResponse.json(data, { status: 201 });
}
```
### Route After
```typescript
async function handler(request: NextRequest) {
const body = await request.json();
const resource = await db.resource.create({ data: body });
return createdResponse(resource);
}
export const POST = withMiddleware(
withAuth,
withRoles(['ADMIN']),
withAudit('CREATE_RESOURCE')
)(handler);
```

# Phase 2: Codebase Migration & Missing Modules (3-4 weeks)
## Overview
Build on Phase 1 infrastructure by migrating existing components and completing missing PRD modules.
## Part A: Component Migration (Week 2-3)
### Priority 1: High-Traffic Components
These fetch from multiple endpoints and cause duplicate requests.
#### 1. `app-layout.tsx` → Migrate to useApiGet()
**Current:** 6 manual fetch calls in separate useEffect blocks
**After:** Single `useApiQueries()` call with caching
**Impact:** ~40 lines → 10 lines, eliminates race conditions
```typescript
// Current (71 lines)
useEffect(() => { fetch('/api/announcements') }, []);
useEffect(() => { fetch('/api/schools') }, []);
useEffect(() => { fetch('/api/user') }, []);
// ... 6 times
// After (10 lines)
const { data } = useApiQueries([
{ url: '/api/announcements', key: 'announcements' },
{ url: '/api/schools', key: 'schools' },
{ url: '/api/user', key: 'user' },
]);
```
#### 2. `analytics-view.tsx` → Extract `AnalyticsDataFetcher` hook
**Current:** 3 useEffect blocks with manual filtering
**After:** Custom hook handling all data logic
**Impact:** Move 100 lines to hook, simplify component to UI-only
#### 3. `attendance-view.tsx` → Consolidate filters
**Current:** Separate state for class/date/filter
**After:** Unified filter state with `useApiGet()` query params
**Impact:** Reduce prop drilling, simplify component
#### 4. `assessments-view.tsx`, `ai-tests-view.tsx` → Merge
**Current:** 2 nearly identical views
**After:** Single `AssessmentsView` with tabs
**Impact:** 300 lines → 200 lines, single source of truth
### Priority 2: Form Components (8-10 each)
Replace with `FormBuilder` or create reusable form components.
#### Student Forms (3 locations)
- `students-view.tsx` - new student form
- `student-details.tsx` - edit student form
- `bulk-student-import.tsx` - batch form
**Strategy:** Create `StudentForm` component wrapping `FormBuilder`
#### Grade Forms (4 locations)
- `grading-view.tsx` - inline grading
- `grade-entry-modal.tsx` - modal grading
- `batch-grading.tsx` - bulk grading
- `ai-grading-audit.tsx` - audit comments
**Strategy:** Create `GradeForm` component using `grading-engine`
#### Assessment Forms (3 locations)
- `assessments-view.tsx` - create/edit
- `ai-tests-view.tsx` - create AI test
- `exam-calendar.tsx` - scheduled assessment
**Strategy:** Create `AssessmentForm` component
### Priority 3: Table Components (8 total)
Replace with unified `DataTable` component.
**Locations:**
- `students-view.tsx` - student list
- `grades-view.tsx` - grade entries
- `attendance-view.tsx` - attendance records
- `analytics-view.tsx` - performance analytics
- `assessments-view.tsx` - assessment list
- `competence-list.tsx` - competency list
- `library-view.tsx` - book inventory
- `report-builder.tsx` - report results
**Migration Pattern:**
```typescript
// Before (80 lines each)
const [sortBy, setSortBy] = useState('name');
const [filterText, setFilterText] = useState('');
// ... manual rendering ...
// After (5 lines)
<DataTable
columns={columns}
data={filteredData}
searchableFields={['firstName', 'lastName', 'email']}
actions={[{label: 'Edit', onClick: handleEdit}]}
/>
```
## Part B: API Route Migration (Week 2-3)
### Route Standardization Strategy
1. Pick one route family (e.g., `/api/v1/students`)
2. Apply middleware + response helpers
3. Test with client using new `useApiGet()`
4. Document as pattern
5. Apply to all other routes
### Priority Routes (in order)
1. **Students API** (4 routes)
- GET /api/v1/students
- POST /api/v1/students
- GET /api/v1/students/[id]
- PUT/DELETE /api/v1/students/[id]
2. **Grades API** (6 routes)
- GET /api/v1/grades
- POST /api/v1/grades
- GET /api/v1/grades/[id]
- PUT /api/v1/grades/[id]
- DELETE /api/v1/grades/[id]
- POST /api/v1/grades/batch
3. **Assessments API** (5 routes)
- GET /api/v1/assessments
- POST /api/v1/assessments
- GET /api/v1/assessments/[id]
- PUT/DELETE /api/v1/assessments/[id]
4. **Attendance API** (4 routes)
5. **Analytics API** (3 routes)
**Each route takes ~30 minutes after first one is done (pattern is clear)**
## Part C: Module Consolidation (Week 3)
### 1. Grading Logic Consolidation
**Status:** `grading-engine.ts` complete, need to refactor existing views
**Views to consolidate:**
- `grading-view.tsx` - manual grading
- `tablet-grading-view.tsx` - tablet UI
- `grade-analytics-view.tsx` - analytics
- `ai-grading-audit.tsx` - AI review + audit
**Steps:**
1. Replace all grading calculations with `grading-engine` functions
2. Use `GradingPanel` for UI
3. Keep AI audit logic separate (Module F feature)
4. Delete old view files after verification
### 2. Calendar Logic Consolidation
**Current:** 3 separate implementations
- `exam-calendar.tsx`
- `event-calendar.tsx`
- `school-calendar.tsx`
**Approach:**
1. Extract calendar engine (similar to grading-engine)
2. Create `CalendarComponent` wrapper
3. Pass different event types as props
4. Merge into single admin calendar view
### 3. Competency Visualization
**Current:** 4 different renderers
- `competence-flower-view.tsx`
- `competence-matrix.tsx`
- `competence-radar.tsx`
- `competence-list.tsx`
**Approach:**
1. Create `CompetencyViewer` component with visualization options
2. Accept `visualizationType` prop
3. Consolidate data fetching
4. Use same grading-engine for calculations
## Part D: Missing Modules (Week 3-4)
### Module B: Complete Signage System
**Database:** ✓ Complete
**Admin UI:** ✓ Core page created
**API:** Need to implement
**Display Client:** New component needed
**Work:**
1. Create signage API endpoints (2-3 hours)
2. Create display client component (1-2 hours)
3. WebSocket integration for live updates (2 hours)
### Module F: Exam Mode (Kiosk Lockdown)
**Database:** Needs `ExamSession`, `ExamLockdown` models
**Admin UI:** Exam configuration page
**Student UI:** Kiosk display component
**API:** Session management endpoints
**Work:** 4-5 days
### Module H: Notifications Hub
**Database:** Needs `Notification`, `NotificationPreference` models
**UI:** Unified notification center
**API:** Notification endpoints
**Integration:** Tie to existing alert system
**Work:** 3-4 days
### Module J: Dashboard Widgets
**Database:** Needs `DashboardWidget`, `WidgetPreference` models
**UI:** Widget system + library
**API:** Widget data endpoints
**Refactor:** Break current monolithic dashboard
**Work:** 4-5 days

# ExaMetra Refactor Action Plan
## PRD v1 → v2 → Production Ready
**Current State Analysis:**
- 70+ view components
- 100+ API routes
- Estimated 40% code duplication
- 4 major PRD v2 modules not implemented
- Multiple memory leak patterns (detected but mostly fixed)
---
## Phase 1: Quick Wins (Week 1)
### 1.1 Implement Centralized API Fetching Hook
**File:** `src/hooks/use-api.ts`
Replace the 60+ identical fetch patterns with SWR:
```tsx
// Before: Repeated in every component
const [data, setData] = useState([]);
const [loading, setLoading] = useState(false);
useEffect(() => {
fetch(`/api/xyz`)
.then(r => r.json())
.then(d => setData(d))
.catch(e => setError(e))
.finally(() => setLoading(false));
}, []);
// After: Single hook in 60+ places
const { data, isLoading, error, mutate } = useApi('/api/xyz');
```
**Impact:** Reduces component code by 30%, fixes data sync issues, enables optimistic updates.
**Affected Files:** 60+ components
---
### 1.2 Extract Reusable UI Components
#### `src/components/ui/data-table.tsx`
Used in: analytics, attendance, competitions, behavior-tracking, grade-analytics
- Sorting, filtering, pagination
- Configurable columns
- Batch actions
#### `src/components/forms/form-builder.tsx`
Used in: student entry, grade entry, assessment creation, subject management
- Schema-driven validation
- Reusable field types
- Error handling
#### `src/components/dialogs/confirm-dialog.tsx`
Used in: 12+ places (delete confirmations, cancel actions)
- Consistent styling
- Accessibility
- Custom actions
**Impact:** Eliminates 25+ duplicate component implementations.
---
### 1.3 Standardize API Response Format
**Current inconsistency:** Some routes return `{ data: [...] }`, others return bare array
**Standard format:**
```json
{
"success": true,
"data": [...],
"error": null,
"pagination": {
"total": 100,
"limit": 20,
"offset": 0
}
}
```
**Create middleware:** `src/lib/api-response.ts`
**Impact:** Simplifies error handling, enables consistent pagination, better client-side caching.
---
### 1.4 Create API Route Middleware
**Problem:** Every route duplicates:
```ts
const session = await getSession();
if (!session?.user?.id) return unauthorized();
await logAudit(session.user.id, action);
```
**Solution:** Higher-order middleware wrapper
```ts
// Before
export async function GET(req: Request) {
const session = await getSession();
if (!session?.user?.id) return unauthorized();
// 50+ lines of actual logic
await logAudit(...);
}
// After
export const GET = withAuth(withAudit(async (req, context) => {
// Just the business logic
const data = await db.xyz.findMany();
return apiResponse(data);
}));
```
**Affected:** All 100+ API routes
**Impact:** Reduces average route size by 40%, eliminates repeated auth/audit code.
---
## Phase 2: Fix Architectural Issues (Weeks 2-3)
### 2.1 Consolidate Grading Logic
**Current duplication:** 3 implementations
- `src/components/grading-view.tsx` — Main grading UI
- `src/components/tablet-grading-view.tsx` — Tablet variant
- `src/components/grade-analytics-view.tsx` — Analytics view
**Problem:** Logic inconsistencies, hard to maintain
**Solution:**
1. Extract grading engine → `src/lib/grading-engine.ts`
- Pure functions for grade computation
- Unit tested
- Reusable everywhere
2. Create UI layer → `src/components/grading/`
- `GradingForm.tsx` — Input component (reusable)
- `GradingView.tsx` — Desktop view (uses GradingForm)
- `TabletGradingView.tsx` — Tablet view (uses GradingForm + responsive)
- `GradeAnalytics.tsx` — Analytics (uses grading-engine)
**Impact:** Single source of truth for grading logic, easier to test, consistent across UI.
---
### 2.2 Unify Assessment Creation
**Current duplication:** 3 implementations
- `assessments-view.tsx` — Standard assessments
- `ai-tests-view.tsx` — AI-generated tests
- `exam-calendar-view.tsx` — Exam scheduling + creation
**Solution:**
1. Create `AssessmentForm.tsx` — Reusable form component
2. Create `AssessmentType.tsx` — Form variant selector (standard/AI-generated/exam)
3. Refactor views to use form component
---
### 2.3 Implement Single Competency Renderer
**Current duplication:** 4 implementations
- `competence-flower-view.tsx` — Radar chart
- `competency-grid-view.tsx` — Grid view
- `mastery-matrix-view.tsx` — Matrix view (duplicate of above)
- `curriculum-coverage-view.tsx` — Coverage view
**Solution:**
```tsx
// New component with configurable layout
<CompetencyViewer
layout="flower" // or "grid" or "matrix" or "coverage"
competencies={competencies}
config={config}
/>
```
**Impact:** Single source of truth for competency data rendering.
---
### 2.4 Unify Calendar Implementations
**Current:** 3 separate calendar components
- `calendar-view.tsx` — General calendar
- `exam-calendar-view.tsx` — Exam-specific calendar
- `lesson-plans-view.tsx` — Lesson scheduling calendar
**Solution:** Single calendar with event type filtering
```tsx
<Calendar
events={allEvents}
eventTypeFilters={['lesson', 'exam', 'deadline']}
config={config}
/>
```
---
## Phase 3: Implement Missing PRD v2 Modules (Weeks 4-6)
### 3.1 Module B — Digital Signage (Emergency Alerts, TV Displays)
**Required tables:**
- `SignageDisplay` — Physical displays
- `SignageSlide` — Content slides
- `SignagePlaylist` — Rotation config
- `EmergencyAlert` — Alert system
**Implementation:**
1. Create admin interface: `/admin/signage/displays`, `/admin/signage/slides`
2. Create display client: `/signage/display/[displayId]` (fullscreen kiosk)
3. Create push notifications for emergency alerts (integrate with Module H)
4. Add approval workflow for teacher-submitted slides
**Safety requirement:** Emergency alerts must override all displays immediately with push notification to staff.
**Effort:** 4–5 days
**Files to create:**
- `src/app/admin/signage/` — Admin pages
- `src/app/signage/display/` — Display client
- `src/components/signage/` — Reusable components
- `src/lib/signage-engine.ts` — Rotation logic
---
### 3.2 Module H — Centralized Notifications
**Required tables:**
- `Notification` — Unified notification model
- `NotificationPreference` — Per-user settings
- `NotificationSubscription` — Service worker subscriptions
**Implementation:**
1. Create `Notification` model unified for all alert types
2. Implement service worker + Web Push API
3. Create notification center UI: `/notifications`
4. Add real-time delivery via WebSocket
5. Refactor all modules to emit into this system instead of creating own alerts
**Current alerts to consolidate:**
- Exam warnings (from exam-calendar-view)
- Messages (from communication-view)
- System alerts (scattered)
- Signage emergencies (new from Module B)
**Effort:** 3–4 days
**Files to create:**
- `src/app/api/notifications/` — Notification API
- `src/app/api/push-subscriptions/` — Web Push setup
- `src/components/notification-center.tsx`
- `src/lib/notification-engine.ts`
- `src/lib/push-service-worker.ts`
---
### 3.3 Module J — Dashboard Widget System (Customizable Home)
**Current issue:** Dashboard monolithic (241KB), not reusable per spec
**Required tables:**
- `DashboardWidget` — Widget definitions
- `UserDashboardPreference` — Per-user layout
- `WidgetData` — Cached widget data (optional)
**Implementation:**
1. Create widget registry system
2. Create `Widget` wrapper component (read-only data consumer)
3. Create customization UI: `/dashboard/customize`
4. Refactor `dashboard-view.tsx` to use widget system
5. Make dashboard widgets available elsewhere (student portal, parent portal)
**Widgets to create (examples):**
- `AttendanceWidget` — Pulls from canonical attendance data
- `UpcomingExamsWidget` — Pulls from calendar
- `GradeWidget` — Pulls from grading system
- `RecentActivitiesWidget` — Pulls from audit log
- `WeatherWidget` — Optional external data
**Each widget must:**
- Fetch from single canonical source (no duplication)
- Be read-only in dashboard context
- Have configurable options (hidden by user preference)
- Load independently with skeleton state
**Effort:** 2–3 days
**Files to create:**
- `src/components/dashboard-widgets/` — Widget implementations
- `src/app/dashboard/customize/` — Customization page
- `src/lib/widget-registry.ts` — Widget system
---
### 3.4 Module F — Exam Mode (Kiosk Lockdown + Proctoring)
**Required tables:**
- `ExamSession` — Active exam session
- `ExamWarning` — Warning log
- `ExamIncidentEvent` — Incident tracking
**Implementation:**
1. Create `ExamSession` model + lifecycle (started → paused → resumed → ended)
2. Implement fullscreen kiosk UI: `/exam/[sessionId]`
3. Add browser-level lockdown:
- Service worker intercepts navigation
- Fullscreen API lock
- Tab/window switching detection
4. Create teacher control panel: `/exam/monitor`
5. Implement warning system (3-strike auto-pause)
6. Add bathroom request flow + distress signal
7. Create incident logging + parent visibility
**Safety requirements:**
- Bathroom requests pause only that student's session
- Distress signal triggers immediate teacher alert
- 3rd warning auto-pauses (not teacher-initiated)
- All incidents logged for audit trail
**Effort:** 5–6 days (complex client-side security)
**Files to create:**
- `src/app/exam/[sessionId]/` — Kiosk page
- `src/app/exam/monitor/` — Teacher control panel
- `src/components/exam-mode/` — Exam UI components
- `src/lib/exam-lockdown.ts` — Kiosk logic
- `src/lib/service-worker-exam.ts` — Browser lockdown
---
## Phase 4: Consolidate Duplicates (Weeks 7-8)
After Phases 1-3, apply architectural changes:
1. **Merge grading implementations** → Single engine + UI variants
2. **Merge assessment creation** → Unified form component
3. **Merge competency renderers** → Configurable component
4. **Merge calendar implementations** → Single calendar with filters
5. **Delete 12+ duplicate utility functions** → Use shared lib
**Result:** Code reduction 30-40%.
---
## Phase 5: Configuration & Compliance (Week 9)
### 5.1 Database Configuration System
Migrate hardcoded values to database:
**Create `SystemConfig` table:**
```ts
{
key: string (PK),
value: string | number | boolean | JSON,
description: string,
editable: boolean,
schoolId: string? (null = system-wide)
}
```
**Migrate:**
- Escalation wait period: "3 business days" → `Config["escalation.wait_days"]`
- Grading scales: hardcoded 1–6 → configurable per school
- Mastery levels: hardcoded 4 levels → configurable
- Report templates: hardcoded phrases → DB-driven
**Effort:** 2 days
---
### 5.2 Role-Based Permission UI
Implement UI-level permission checks:
```tsx
// Before: Just hidden, not prevented
{userRole === 'ADMIN' && <AdminButton />}
// After: Proper permission check
<ProtectedFeature feature="admin.grading" fallback={<LockedIcon />}>
<AdminButton />
</ProtectedFeature>
```
**Effort:** 1 day
---
## Timeline Summary
| Phase | Duration | Completion |
|-------|----------|------------|
| Phase 1 (Quick Wins) | 1 week | Reduce duplication by 30% |
| Phase 2 (Architecture) | 2 weeks | Consolidate major duplicates |
| Phase 3 (Missing Modules) | 3 weeks | Implement B, H, J, F |
| Phase 4 (Consolidation) | 1 week | Final cleanup |
| Phase 5 (Config) | 1 week | Database config system |
| **Total** | **~9 weeks** | **Production ready** |
---
## Immediate Next Steps

# API Standardization Guide
## Overview
All API routes must follow this standardized format for consistency, maintainability, and predictable client-side behavior.
## Response Format
### Success Response (GET, POST, PUT, PATCH)
```json
{
"success": true,
"data": { /* actual data */ },
"timestamp": "2024-01-01T12:00:00Z",
"path": "/api/v1/students"
}
```
### Error Response
```json
{
"success": false,
"error": "Descriptive error message",
"timestamp": "2024-01-01T12:00:00Z",
"path": "/api/v1/students"
}
```
### Delete Response (204 No Content)
No body, just status 204
## Status Codes
| Code | Meaning | Use Case |
|------|---------|----------|
| 200 | OK | GET, PUT, PATCH success |
| 201 | Created | POST success |
| 204 | No Content | DELETE success |
| 400 | Bad Request | Invalid input data |
| 401 | Unauthorized | Not authenticated |
| 403 | Forbidden | Authenticated but no permission |
| 404 | Not Found | Resource doesn't exist |
| 422 | Unprocessable | Validation error |
| 500 | Server Error | Unhandled exception |
## Route Structure
### Before (Inconsistent)
```typescript
export async function POST(request: Request) {
try {
const session = await getSession();
if (!session) {
return NextResponse.json({ error: 'Not authenticated' }, { status: 401 });
}
// ... 100 lines of mixed logic
if (!resource) {
return NextResponse.json({ error: 'Not found' }, { status: 404 });
}
// Multiple different response formats
return NextResponse.json(resource, { status: 201 });
} catch (error) {
return NextResponse.json({ error: 'Internal server error' }, { status: 500 });
}
}
```
### After (Standardized)
```typescript
import { NextRequest } from 'next/server';
import { withMiddleware, withAuth, withRoles, withAudit } from '@/lib/route-middleware';
import { successResponse, createdResponse, notFoundError, validationError } from '@/lib/api-response';
import { db } from '@/lib/db';
async function handler(request: NextRequest) {
const body = await request.json();
const { resourceId } = body;
if (!resourceId) {
return validationError('resourceId is required');
}
const resource = await db.resource.create({ data: body });
if (!resource) {
return notFoundError('Resource creation failed');
}
return createdResponse(resource);
}
export const POST = withMiddleware(
withAuth,
withRoles(['TEACHER', 'ADMIN']),
withAudit('CREATE_RESOURCE')
)(handler);
```
## Using API Response Helpers
All routes should use helpers from `@/lib/api-response`:
```typescript
import {
successResponse,
createdResponse,
noContentResponse,
unauthorizedError,
forbiddenError,
notFoundError,
validationError,
serverError,
} from '@/lib/api-response';
// GET - return data
return successResponse(data);
// POST - return created resource
return createdResponse(resource);
// DELETE - no content
return noContentResponse();
// Errors
return unauthorizedError();
return forbiddenError();
return notFoundError('Resource not found');
return validationError('Invalid email format');
return serverError(error);
```
## Using Middleware
### Basic Authentication
```typescript
import { withAuth } from '@/lib/route-middleware';
async function handler(request: NextRequest) {
const user = (request as any).user; // injected by middleware
// handler logic
}
export const GET = withAuth(handler);
```
### Role-Based Access
```typescript
import { withRoles } from '@/lib/route-middleware';
async function handler(request: NextRequest) {
// only TEACHER and ADMIN can access
}
export const POST = withRoles(['TEACHER', 'ADMIN'])(handler);
```
### Audit Logging
```typescript
import { withAudit } from '@/lib/route-middleware';
export const DELETE = withAudit('DELETE_STUDENT')(handler);
```
### Combining Middleware
```typescript
import { withMiddleware, withAuth, withRoles, withAudit } from '@/lib/route-middleware';
export const PUT = withMiddleware(
withAuth,
withRoles(['TEACHER', 'ADMIN']),
withAudit('UPDATE_GRADES')
)(handler);
```
## Client-Side Usage
### With useApiGet (for data fetching)
```typescript
import { useApiGet } from '@/lib/hooks/useApi';
function MyComponent() {
const { data, error, isLoading, mutate } = useApiGet('/api/v1/students');
if (isLoading) return <div>Loading...</div>;
if (error) return <div>Error: {error.message}</div>;
return <div>{data.map(s => <div key={s.id}>{s.name}</div>)}</div>;
}
```
### With useApiMutation (for mutations)
```typescript
import { useApiMutation } from '@/lib/hooks/useApi';
function MyComponent() {
const { mutate, isLoading, error } = useApiMutation('/api/v1/students', {
method: 'POST',
onSuccess: (data) => console.log('Created:', data),
onError: (error) => console.error('Error:', error),
});
const handleCreate = async () => {
await mutate({ name: 'John', email: 'john@example.com' });
};
return <button onClick={handleCreate} disabled={isLoading}>Create</button>;
}
```
## Migration Checklist
When standardizing an existing route:
- [ ] Import helpers from `@/lib/api-response`
- [ ] Import middleware from `@/lib/route-middleware`
- [ ] Replace inline auth check with `withAuth`
- [ ] Replace inline role check with `withRoles`
- [ ] Replace inline error handling with response helpers
- [ ] Add `withAudit` for sensitive operations
- [ ] Ensure all responses use standardized format
- [ ] Test with client using new `useApiGet`/`useApiMutation`
- [ ] Update any direct `fetch` calls to use hooks
## Common Patterns
### List with Filtering/Pagination
```typescript
async function handler(request: NextRequest) {
const { searchParams } = new URL(request.url);
const page = parseInt(searchParams.get('page') || '1');
const limit = parseInt(searchParams.get('limit') || '20');
const [data, total] = await Promise.all([
db.resource.findMany({
skip: (page - 1) * limit,
take: limit,
}),
db.resource.count(),
]);
return successResponse({
data,
pagination: { page, limit, total, pages: Math.ceil(total / limit) },
});
}
```
### Nested Route with ID
```typescript
async function handler(request: NextRequest, { params }: any) {
const { id } = await params;
const resource = await db.resource.findUnique({ where: { id } });
if (!resource) {
return notFoundError(`Resource ${id} not found`);
}
return successResponse(resource);
}
```
### Batch Operations
```typescript
async function handler(request: NextRequest) {
const { ids } = await request.json();
const deleted = await db.resource.deleteMany({
where: { id: { in: ids } },
});
return successResponse({
deletedCount: deleted.count,
ids,
});
}
```
## Benefits
1. **Predictable** - Clients know exactly what format to expect
2. **Debuggable** - Timestamps and paths help track issues
3. **DRY** - Reusable middleware eliminates boilerplate
4. **Testable** - Standardized responses are easier to test
5. **Maintainable** - Consistent patterns across all routes
6. **Safe** - Automatic error handling reduces bugs
