# Critical Fixes - Quick Reference Guide
|
||||
|
||||
## 🚨 Top 5 Critical Fixes (Do These First)
|
||||
|
||||
### 1. Fix useNotifications Memory Leak ⚠️ CRITICAL
|
||||
|
||||
**File**: `hooks/use-notifications.ts`
|
||||
**Line**: 239-255
|
||||
|
||||
**Problem**: Cleanup function not properly placed, causing memory leaks
|
||||
|
||||
**Quick Fix**:
|
||||
```typescript
|
||||
useEffect(() => {
|
||||
if (status !== 'authenticated' || !session?.user) return;
|
||||
|
||||
isMountedRef.current = true;
|
||||
|
||||
// Initial fetch
|
||||
fetchNotificationCount(true);
|
||||
fetchNotifications();
|
||||
|
||||
// Start polling with proper cleanup
|
||||
const intervalId = setInterval(() => {
|
||||
if (isMountedRef.current) {
|
||||
debouncedFetchCount();
|
||||
}
|
||||
}, POLLING_INTERVAL);
|
||||
|
||||
// ✅ Proper cleanup
|
||||
return () => {
|
||||
isMountedRef.current = false;
|
||||
clearInterval(intervalId);
|
||||
};
|
||||
}, [status, session?.user?.id]); // ✅ Only primitive dependencies
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. Fix Notification Badge Double Fetching ⚠️ CRITICAL
|
||||
|
||||
**File**: `components/notification-badge.tsx`
|
||||
**Lines**: 65-70, 82-87, 92-99
|
||||
|
||||
**Problem**: Three different places trigger the same fetch simultaneously
|
||||
|
||||
**Quick Fix**:
|
||||
```typescript
|
||||
// Add at top of component
|
||||
const fetchInProgressRef = useRef(false);
|
||||
const lastFetchRef = useRef<number>(0);
|
||||
const FETCH_COOLDOWN = 1000; // 1 second cooldown
|
||||
|
||||
const manualFetch = async () => {
|
||||
const now = Date.now();
|
||||
|
||||
// Prevent duplicate fetches
|
||||
if (fetchInProgressRef.current) {
|
||||
console.log('[NOTIFICATION_BADGE] Fetch already in progress');
|
||||
return;
|
||||
}
|
||||
|
||||
// Cooldown check
|
||||
if (now - lastFetchRef.current < FETCH_COOLDOWN) {
|
||||
console.log('[NOTIFICATION_BADGE] Too soon since last fetch');
|
||||
return;
|
||||
}
|
||||
|
||||
fetchInProgressRef.current = true;
|
||||
lastFetchRef.current = now;
|
||||
|
||||
try {
|
||||
await fetchNotifications(1, 10);
|
||||
} finally {
|
||||
fetchInProgressRef.current = false;
|
||||
}
|
||||
};
|
||||
|
||||
// Remove duplicate useEffect hooks, keep only one:
|
||||
useEffect(() => {
|
||||
if (isOpen && status === 'authenticated') {
|
||||
manualFetch();
|
||||
}
|
||||
}, [isOpen, status]); // Only this one
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 3. Fix Redis KEYS Performance Issue ⚠️ CRITICAL
|
||||
|
||||
**File**: `lib/services/notifications/notification-service.ts`
|
||||
**Line**: 293
|
||||
|
||||
**Problem**: `redis.keys()` blocks Redis and is O(N)
|
||||
|
||||
**Quick Fix**:
|
||||
```typescript
|
||||
// BEFORE (Line 293)
|
||||
const listKeys = await redis.keys(listKeysPattern);
|
||||
if (listKeys.length > 0) {
|
||||
await redis.del(...listKeys);
|
||||
}
|
||||
|
||||
// AFTER (Use SCAN)
|
||||
const listKeys: string[] = [];
|
||||
let cursor = '0';
|
||||
do {
|
||||
const [nextCursor, keys] = await redis.scan(
|
||||
cursor,
|
||||
'MATCH',
|
||||
listKeysPattern,
|
||||
'COUNT',
|
||||
100
|
||||
);
|
||||
cursor = nextCursor;
|
||||
if (keys.length > 0) {
|
||||
listKeys.push(...keys);
|
||||
}
|
||||
} while (cursor !== '0');
|
||||
|
||||
if (listKeys.length > 0) {
|
||||
await redis.del(...listKeys);
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
### 4. Fix Widget Interval Cleanup ⚠️ HIGH
|
||||
|
||||
**Files**:
|
||||
- `components/calendar.tsx` (line 70)
|
||||
- `components/parole.tsx` (line 83)
|
||||
- `components/calendar/calendar-widget.tsx` (line 110)
|
||||
|
||||
**Problem**: Intervals may not be cleaned up properly
|
||||
|
||||
**Quick Fix Pattern**:
|
||||
```typescript
|
||||
// BEFORE
|
||||
useEffect(() => {
|
||||
fetchEvents();
|
||||
const intervalId = setInterval(fetchEvents, 300000);
|
||||
return () => clearInterval(intervalId);
|
||||
}, []); // ❌ Missing dependencies
|
||||
|
||||
// AFTER
|
||||
useEffect(() => {
|
||||
if (status !== 'authenticated') return;
|
||||
|
||||
const fetchEvents = async () => {
|
||||
// ... fetch logic
|
||||
};
|
||||
|
||||
fetchEvents(); // Initial fetch
|
||||
|
||||
const intervalId = setInterval(fetchEvents, 300000);
|
||||
|
||||
return () => {
|
||||
clearInterval(intervalId);
|
||||
};
|
||||
}, [status]); // ✅ Proper dependencies
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 5. Fix useEffect Infinite Loop Risk ⚠️ HIGH
|
||||
|
||||
**File**: `hooks/use-notifications.ts`
|
||||
**Line**: 255
|
||||
|
||||
**Problem**: Function dependencies cause infinite re-renders
|
||||
|
||||
**Quick Fix**:
|
||||
```typescript
|
||||
// Remove function dependencies, use refs for stable references
|
||||
const fetchNotificationCountRef = useRef(fetchNotificationCount);
|
||||
const fetchNotificationsRef = useRef(fetchNotifications);
|
||||
|
||||
useEffect(() => {
|
||||
fetchNotificationCountRef.current = fetchNotificationCount;
|
||||
fetchNotificationsRef.current = fetchNotifications;
|
||||
});
|
||||
|
||||
useEffect(() => {
|
||||
if (status !== 'authenticated' || !session?.user) return;
|
||||
|
||||
isMountedRef.current = true;
|
||||
|
||||
fetchNotificationCountRef.current(true);
|
||||
fetchNotificationsRef.current();
|
||||
|
||||
const intervalId = setInterval(() => {
|
||||
if (isMountedRef.current) {
|
||||
fetchNotificationCountRef.current();
|
||||
}
|
||||
}, POLLING_INTERVAL);
|
||||
|
||||
return () => {
|
||||
isMountedRef.current = false;
|
||||
clearInterval(intervalId);
|
||||
};
|
||||
}, [status, session?.user?.id]); // ✅ Only primitive values
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🔧 Additional Quick Wins
|
||||
|
||||
### 6. Add Request Deduplication Utility
|
||||
|
||||
**Create**: `lib/utils/request-deduplication.ts`
|
||||
|
||||
```typescript
|
||||
const pendingRequests = new Map<string, Promise<any>>();
|
||||
|
||||
export function deduplicateRequest<T>(
|
||||
key: string,
|
||||
requestFn: () => Promise<T>
|
||||
): Promise<T> {
|
||||
if (pendingRequests.has(key)) {
|
||||
return pendingRequests.get(key)!;
|
||||
}
|
||||
|
||||
const promise = requestFn().finally(() => {
|
||||
pendingRequests.delete(key);
|
||||
});
|
||||
|
||||
pendingRequests.set(key, promise);
|
||||
return promise;
|
||||
}
|
||||
```
|
||||
|
||||
**Usage**:
|
||||
```typescript
|
||||
const data = await deduplicateRequest(
|
||||
`notifications-${userId}`,
|
||||
() => fetch('/api/notifications').then(r => r.json())
|
||||
);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 7. Extract Magic Numbers to Constants
|
||||
|
||||
**Create**: `lib/constants/intervals.ts`
|
||||
|
||||
```typescript
|
||||
export const INTERVALS = {
|
||||
NOTIFICATION_POLLING: 60000, // 1 minute
|
||||
CALENDAR_REFRESH: 300000, // 5 minutes
|
||||
PAROLE_POLLING: 30000, // 30 seconds
|
||||
MIN_FETCH_INTERVAL: 5000, // 5 seconds
|
||||
FETCH_COOLDOWN: 1000, // 1 second
|
||||
} as const;
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 8. Add Error Retry Logic
|
||||
|
||||
**Create**: `lib/utils/retry.ts`
|
||||
|
||||
```typescript
|
||||
export async function retry<T>(
|
||||
fn: () => Promise<T>,
|
||||
maxAttempts = 3,
|
||||
delay = 1000
|
||||
): Promise<T> {
|
||||
for (let attempt = 1; attempt <= maxAttempts; attempt++) {
|
||||
try {
|
||||
return await fn();
|
||||
} catch (error) {
|
||||
if (attempt === maxAttempts) throw error;
|
||||
await new Promise(resolve => setTimeout(resolve, delay * attempt));
|
||||
}
|
||||
}
|
||||
throw new Error('Max retry attempts reached');
|
||||
}
|
||||
```

1. **Keep old code**: Don't delete old implementations immediately
|
||||
2. **Feature flag**: Use environment variable to toggle new/old system
|
||||
3. **Gradual migration**: Migrate one widget at a time
|
||||
4. **Monitor**: Watch for errors in production
|
||||

|
||||
## 📝 Notes
|
||||
|
||||
- All new code should be backward compatible
|
||||
- Test each phase before moving to next
|
||||
- Document any deviations from plan
|
||||
- Update this checklist as you progress

# Implementation Plan: Unified Refresh System
|
||||
|
||||
## 🎯 Goals
|
||||
|
||||
1. **Harmonize auto-refresh** across all widgets and notifications
|
||||
2. **Reduce redundancy** and eliminate duplicate API calls
|
||||
3. **Improve API efficiency** with request deduplication and caching
|
||||
4. **Prevent memory leaks** with proper cleanup mechanisms
|
||||
5. **Centralize refresh logic** for easier maintenance
|
||||
|
||||
---
|
||||
|
||||
## 📋 Current State Analysis
|
||||
|
||||
### Current Refresh Intervals:
|
||||
- **Notifications**: 60 seconds (polling)
|
||||
- **Calendar**: 5 minutes (300000ms)
|
||||
- **Parole (Chat)**: 30 seconds (30000ms)
|
||||
- **Navbar Time**: Static (not refreshing - needs fix)
|
||||
- **News**: Manual only
|
||||
- **Email**: Manual only
|
||||
- **Duties (Tasks)**: Manual only
|
||||
|
||||
### Current Problems:
|
||||
1. ❌ No coordination between widgets
|
||||
2. ❌ Duplicate API calls from multiple components
|
||||
3. ❌ Memory leaks from uncleaned intervals
|
||||
4. ❌ No request deduplication
|
||||
5. ❌ Inconsistent refresh patterns

### Phase 2: Harmonized Refresh Intervals
|

---
|
||||
|
||||
## 🚀 Quick Start Implementation
|
||||
|
||||
### Priority Order:
|
||||
|
||||
1. **Critical** (Do First):
|
||||
- Fix memory leaks
|
||||
- Create refresh manager
|
||||
- Create request deduplication
|
||||
|
||||
2. **High** (Do Second):
|
||||
- Refactor notifications
|
||||
- Refactor high-frequency widgets (parole, notifications)
|
||||
|
||||
3. **Medium** (Do Third):
|
||||
- Refactor medium-frequency widgets (email, duties)
|
||||
|
||||
4. **Low** (Do Last):
|
||||
- Refactor low-frequency widgets (calendar, news)
|
||||
|
||||
---

# Navigation Bar Time Integration
|
||||
|
||||
## 🎯 Overview
|
||||
|
||||
The navigation bar (`components/main-nav.tsx`) currently displays a static time that doesn't refresh. This document outlines how to integrate it into the unified refresh system.
|
||||
|
||||
## 🔍 Current Issue
|
||||
|
||||
**File**: `components/main-nav.tsx` (lines 228-231)
|
||||
|
||||
```typescript
|
||||
// Current code - STATIC (doesn't refresh)
|
||||
const now = new Date();
|
||||
const formattedDate = format(now, "d MMMM yyyy", { locale: fr });
|
||||
const formattedTime = format(now, "HH:mm");
|
||||
```
|
||||
|
||||
**Problem**: Time is calculated once when component renders and never updates.
|
||||
|
||||
## ✅ Solution
|
||||
|
||||
### Step 1: Create Time Component
|
||||
|
||||
**File**: `components/main-nav-time.tsx` (✅ Already created)
|
||||
|
||||
This component:
|
||||
- Uses `useState` to track current time
|
||||
- Uses `useUnifiedRefresh` hook for 1-second updates
|
||||
- Properly cleans up on unmount
|
||||
- No API calls needed (client-side only)
|
||||
|
||||
### Step 2: Update MainNav Component
|
||||
|
||||
**File**: `components/main-nav.tsx`
|
||||
|
||||
**Changes needed**:
|
||||
|
||||
1. **Import the new component**:
|
||||
```typescript
|
||||
import { MainNavTime } from './main-nav-time';
|
||||
```
|
||||
|
||||
2. **Remove static time code** (lines 228-231):
|
||||
```typescript
|
||||
// DELETE THESE LINES:
|
||||
// Format current date and time
|
||||
const now = new Date();
|
||||
const formattedDate = format(now, "d MMMM yyyy", { locale: fr });
|
||||
const formattedTime = format(now, "HH:mm");
|
||||
```
|
||||
|
||||
3. **Replace time display** (lines 294-298):
|
||||
```typescript
|
||||
// BEFORE:
|
||||
{/* Center - Date and Time */}
|
||||
<div className="hidden md:flex flex-col items-center">
|
||||
<div className="text-white/80 text-xs">{formattedDate}</div>
|
||||
<div className="text-white text-sm font-medium">{formattedTime}</div>
|
||||
</div>
|
||||
|
||||
// AFTER:
|
||||
{/* Center - Date and Time */}
|
||||
<MainNavTime />
|
||||
```
|
||||
|
||||
### Step 3: Verify Integration
|
||||
|
||||
After changes:
|
||||
- ✅ Time updates every second
|
||||
- ✅ Uses unified refresh system
|
||||
- ✅ Proper cleanup on unmount
|
||||
- ✅ No memory leaks
|
||||
- ✅ Consistent with other widgets
|
||||
|
||||
## 📊 Benefits
|
||||
|
||||
1. **Real-time clock**: Time updates every second
|
||||
2. **Unified system**: Uses same refresh manager as widgets
|
||||
3. **Memory safe**: Proper cleanup prevents leaks
|
||||
4. **Consistent**: Same pattern as other components
|
||||
5. **Maintainable**: Centralized refresh logic
|
||||
|
||||
## 🔧 Technical Details
|
||||
|
||||
### Refresh Configuration
|
||||
|
||||
- **Resource**: `navbar-time`
|
||||
- **Interval**: 1000ms (1 second)
|
||||
- **Priority**: `high` (real-time display)
|
||||
- **API Calls**: None (client-side only)
|
||||
- **Cleanup**: Automatic via `useUnifiedRefresh`
|
||||
|
||||
### Integration with Refresh Manager
|
||||
|
||||
The time component registers with the refresh manager:
|
||||
|
||||
```typescript
|
||||
useUnifiedRefresh({
|
||||
resource: 'navbar-time',
|
||||
interval: REFRESH_INTERVALS.NAVBAR_TIME, // 1000ms
|
||||
enabled: true, // Always enabled
|
||||
onRefresh: async () => {
|
||||
setCurrentTime(new Date());
|
||||
},
|
||||
priority: 'high',
|
||||
});
|
||||
```
|
||||
|
||||
## ✅ Implementation Checklist
|
||||
|
||||
- [x] Create `components/main-nav-time.tsx`
|
||||
- [x] Add `NAVBAR_TIME` to refresh intervals
|
||||
- [x] Add `navbar-time` to refreshable resources
|
||||
- [ ] Update `components/main-nav.tsx` to use new component
|
||||
- [ ] Test time updates correctly
|
||||
- [ ] Verify cleanup on unmount
|
||||
- [ ] Test with multiple tabs
|
||||
|
||||
## 🎯 Expected Result
|
||||
|
||||
After implementation:
|
||||
- Time updates smoothly every second
|
||||
- No performance impact
|
||||
- No memory leaks
|
||||
- Consistent with unified refresh system

### Widget Update Patterns
|
||||
|
||||
#### Common Update Mechanisms:
|
||||
|
||||
1. **Manual Refresh**:
|
||||
- All widgets have a refresh button in their header
|
||||
- Triggers API call with `refresh=true` parameter
|
||||
- Shows loading/spinning state during refresh
|
||||
|
||||
2. **Auto Refresh/Polling**:
|
||||
- **Calendar**: 5 minutes interval
|
||||
- **Parole**: 30 seconds interval
|
||||
- Others: On component mount only
|
||||
|
||||
3. **Session-Based Loading**:
|
||||
- Widgets check authentication status
|
||||
- Only fetch data when `status === 'authenticated'`
|
||||
- Show loading state during authentication check
|
||||
|
||||
4. **Error Handling**:
|
||||
- All widgets display error messages
|
||||
- Retry buttons available
|
||||
- Graceful degradation (empty states)
|
||||
|
||||
5. **State Management**:
|
||||
- All widgets use React `useState` hooks
|
||||
- Loading states managed locally
|
||||
- Error states managed locally
|
||||
|
||||

## 📝 Notes
|
||||
|
||||
1. **Notification Sources**: Currently only Leantime adapter is implemented. Other adapters (Nextcloud, Gitea, Dolibarr, Moodle) are commented out in the service.
|
||||
|
||||
2. **Cache Strategy**:
|
||||
- Notification counts: 30 seconds TTL
|
||||
- Notification lists: 5 minutes TTL
|
||||
- Widget data: Varies by widget (some use API-level caching)
|
||||
|
||||
3. **Polling Intervals**:
|
||||
- Notifications: 60 seconds
|
||||
- Calendar widget: 5 minutes
|
||||
- Parole widget: 30 seconds
|
||||
- Other widgets: On mount only
|
||||
|
||||
4. **Authentication**: All notification and widget APIs require authentication via NextAuth session.
|
||||
|
||||
5. **Error Handling**: All components implement error states with retry mechanisms.
|
||||
|
||||

|
||||
|
||||
## 🔍 Debugging
|
||||
|
||||
- Use `/api/debug/notifications` to test notification system
|
||||
- Check browser console for detailed logs (all components log extensively)
|
||||
- Check Redis cache keys: `notifications:count:{userId}`, `notifications:list:{userId}:{page}:{limit}`

# Stack Quality & Flow Analysis Report
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document provides a comprehensive analysis of the codebase quality, architecture patterns, and identifies critical issues in the notification and widget update flows.
|
||||
|
||||
**Overall Assessment**: ⚠️ **Moderate Quality** - Good foundation with several critical issues that need attention.
|
||||
|
||||
---
|
||||
|
||||
## 🔴 Critical Issues
|
||||
|
||||
### 1. **Memory Leak: Multiple Polling Intervals**
|
||||
|
||||
**Location**: `hooks/use-notifications.ts`, `components/parole.tsx`, `components/calendar/calendar-widget.tsx`
|
||||
|
||||
**Problem**:
|
||||
- `useNotifications` hook creates polling intervals that may not be properly cleaned up
|
||||
- Multiple components using the hook can create duplicate intervals
|
||||
- `startPolling()` returns a cleanup function but it's not properly used in the useEffect
|
||||
|
||||
**Code Issue**:
|
||||
```typescript
|
||||
// Line 226 in use-notifications.ts
|
||||
return () => stopPolling(); // This return is inside startPolling, not useEffect!
|
||||
```
|
||||
|
||||
**Impact**: Memory leaks, excessive API calls, degraded performance
|
||||
|
||||
**Fix Required**:
|
||||
```typescript
|
||||
useEffect(() => {
|
||||
isMountedRef.current = true;
|
||||
|
||||
if (status === 'authenticated' && session?.user) {
|
||||
fetchNotificationCount(true);
|
||||
fetchNotifications();
|
||||
startPolling();
|
||||
}
|
||||
|
||||
return () => {
|
||||
isMountedRef.current = false;
|
||||
stopPolling(); // ✅ Correct placement
|
||||
};
|
||||
}, [status, session?.user, fetchNotificationCount, fetchNotifications, startPolling, stopPolling]);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. **Race Condition: Notification Badge Double Fetching**
|
||||
|
||||
**Location**: `components/notification-badge.tsx`
|
||||
|
||||
**Problem**:
|
||||
- Multiple `useEffect` hooks trigger `manualFetch()` simultaneously
|
||||
- Lines 65-70, 82-87, and 92-99 all trigger fetches
|
||||
- No debouncing or request deduplication
|
||||
|
||||
**Code Issue**:
|
||||
```typescript
|
||||
// Line 65-70: Fetch on dropdown open
|
||||
useEffect(() => {
|
||||
if (isOpen && status === 'authenticated') {
|
||||
manualFetch();
|
||||
}
|
||||
}, [isOpen, status]);
|
||||
|
||||
// Line 82-87: Fetch on mount
|
||||
useEffect(() => {
|
||||
if (status === 'authenticated') {
|
||||
manualFetch();
|
||||
}
|
||||
}, [status]);
|
||||
|
||||
// Line 92-99: Fetch on handleOpenChange
|
||||
const handleOpenChange = (open: boolean) => {
|
||||
setIsOpen(open);
|
||||
if (open && status === 'authenticated') {
|
||||
manualFetch(); // Duplicate fetch!
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
**Impact**: Unnecessary API calls, potential race conditions, poor UX
|
||||
|
||||
**Fix Required**: Consolidate fetch logic, add request deduplication
|
||||

|
||||
|
||||
### 3. **Redis KEYS Command Performance Issue**
|
||||
|
||||
**Location**: `lib/services/notifications/notification-service.ts` (line 293)
|
||||
|
||||
**Problem**:
|
||||
- Using `redis.keys()` which is O(N) and blocks Redis
|
||||
- Can cause performance degradation in production
|
||||
|
||||
**Code Issue**:
|
||||
```typescript
|
||||
// Line 293 - BAD
|
||||
const listKeys = await redis.keys(listKeysPattern);
|
||||
if (listKeys.length > 0) {
|
||||
await redis.del(...listKeys);
|
||||
}
|
||||
```
|
||||
|
||||
**Impact**: Redis blocking, slow response times, potential timeouts
|
||||
|
||||
**Fix Required**: Use `SCAN` instead of `KEYS`:
|
||||
```typescript
|
||||
// GOOD - Use SCAN
|
||||
let cursor = '0';
|
||||
do {
|
||||
const [nextCursor, keys] = await redis.scan(cursor, 'MATCH', listKeysPattern, 'COUNT', 100);
|
||||
cursor = nextCursor;
|
||||
if (keys.length > 0) {
|
||||
await redis.del(...keys);
|
||||
}
|
||||
} while (cursor !== '0');
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. **Infinite Loop Risk: useEffect Dependencies**
|
||||
|
||||
**Location**: `hooks/use-notifications.ts` (line 255)
|
||||
|
||||
**Problem**:
|
||||
- `useEffect` includes functions in dependencies that are recreated on every render
|
||||
- `fetchNotificationCount`, `fetchNotifications`, `startPolling`, `stopPolling` are in deps
|
||||
- These functions depend on `session?.user` which changes, causing re-renders
|
||||
|
||||
**Code Issue**:
|
||||
```typescript
|
||||
useEffect(() => {
|
||||
// ...
|
||||
}, [status, session?.user, fetchNotificationCount, fetchNotifications, startPolling, stopPolling]);
|
||||
// ❌ Functions are recreated, causing infinite loops
|
||||
```
|
||||
|
||||
**Impact**: Infinite re-renders, excessive API calls, browser freezing
|
||||
|
||||
**Fix Required**: Remove function dependencies or use `useCallback` properly
|
||||
|
||||
---
|
||||
|
||||
### 5. **Background Refresh Memory Leak**
|
||||
|
||||
**Location**: `lib/services/notifications/notification-service.ts` (line 326)
|
||||
|
||||
**Problem**:
|
||||
- `setTimeout` in `scheduleBackgroundRefresh` creates closures that may not be cleaned up
|
||||
- No way to cancel pending background refreshes
|
||||
- Can accumulate in serverless environments
|
||||
|
||||
**Code Issue**:
|
||||
```typescript
|
||||
setTimeout(async () => {
|
||||
// This closure holds references and may not be garbage collected
|
||||
await this.getNotificationCount(userId);
|
||||
await this.getNotifications(userId, 1, 20);
|
||||
}, 0);
|
||||
```
|
||||
|
||||
**Impact**: Memory leaks, especially in serverless/edge environments
|
||||
|
||||
**Fix Required**: Use proper cleanup mechanism or job queue
|
||||
|
||||

|
||||
|
||||
## ⚠️ High Priority Issues
|
||||
|
||||
### 6. **Widget Update Race Conditions**
|
||||
|
||||
**Location**: Multiple widget components
|
||||
|
||||
**Problem**:
|
||||
- Widgets don't coordinate updates
|
||||
- Multiple widgets can trigger simultaneous API calls
|
||||
- No request deduplication
|
||||
|
||||
**Affected Widgets**:
|
||||
- `components/calendar.tsx` - Auto-refresh every 5 minutes
|
||||
- `components/parole.tsx` - Auto-polling every 30 seconds
|
||||
- `components/news.tsx` - Manual refresh only
|
||||
- `components/flow.tsx` - Manual refresh only
|
||||
- `components/email.tsx` - Manual refresh only
|
||||
|
||||
**Impact**: Unnecessary load on backend, potential rate limiting
|
||||
|
||||
**Fix Required**: Implement request deduplication layer or use React Query/SWR
|
||||
|
||||
---
|
||||
|
||||
### 7. **Redis Connection Singleton Issues**
|
||||
|
||||
**Location**: `lib/redis.ts`
|
||||
|
||||
**Problem**:
|
||||
- Singleton pattern but no proper connection pooling
|
||||
- In serverless environments, connections may not be reused
|
||||
- No connection health monitoring
|
||||
- Race condition in `getRedisClient()` when `isConnecting` is true
|
||||
|
||||
**Code Issue**:
|
||||
```typescript
|
||||
if (isConnecting) {
|
||||
if (redisClient) return redisClient;
|
||||
// ⚠️ What if redisClient is null but isConnecting is true?
|
||||
console.warn('Redis connection in progress, creating temporary client');
|
||||
}
|
||||
```
|
||||
|
||||
**Impact**: Connection leaks, connection pool exhaustion, degraded performance
|
||||
|
||||
**Fix Required**: Implement proper connection pool or use Redis connection manager
|
||||
|
||||
---
|
||||
|
||||
### 8. **Error Handling Gaps**
|
||||
|
||||
**Location**: Multiple files
|
||||
|
||||
**Problems**:
|
||||
- Errors are logged but not always handled gracefully
|
||||
- No retry logic for transient failures
|
||||
- No circuit breaker pattern
|
||||
- Widgets show errors but don't recover automatically
|
||||
|
||||
**Examples**:
|
||||
- `components/notification-badge.tsx` - Shows error but no auto-retry
|
||||
- `lib/services/notifications/notification-service.ts` - Errors return empty arrays silently
|
||||
- Widget components - Errors stop updates, no recovery
|
||||
|
||||
**Impact**: Poor UX, silent failures, degraded functionality
|
||||
|
||||
---
|
||||
|
||||
### 9. **Cache Invalidation Issues**
|
||||
|
||||
**Location**: `lib/services/notifications/notification-service.ts`
|
||||
|
||||
**Problem**:
|
||||
- Cache invalidation uses `KEYS` command (blocking)
|
||||
- No partial cache invalidation
|
||||
- Background refresh may not invalidate properly
|
||||
- Race condition: cache can be invalidated while being refreshed
|
||||
|
||||
**Impact**: Stale data, inconsistent state
|
||||
|
||||
---
|
||||
|
||||
### 10. **Excessive Logging**
|
||||
|
||||
**Location**: Throughout codebase
|
||||
|
||||
**Problem**:
|
||||
- Console.log statements everywhere
|
||||
- No log levels
|
||||
- Production code has debug logs
|
||||
- Performance impact from string concatenation
|
||||
|
||||
**Impact**: Performance degradation, log storage costs, security concerns
|
||||
|
||||
**Fix Required**: Use proper logging library with levels (e.g., Winston, Pino)
|
||||
|

## 🔄 Flow Analysis
|
||||
|
||||
### Notification Flow Issues
|
||||
|
||||
#### Flow Diagram (Current - Problematic):
|
||||
```
|
||||
User Action / Polling
|
||||
↓
|
||||
useNotifications Hook (multiple instances)
|
||||
↓
|
||||
Multiple API Calls (no deduplication)
|
||||
↓
|
||||
NotificationService (Redis cache check)
|
||||
↓
|
||||
Adapter Calls (parallel, but no error aggregation)
|
||||
↓
|
||||
Response (may be stale due to race conditions)
|
||||
```
|
||||
|
||||
#### Issues:
|
||||
1. **Multiple Hook Instances**: `NotificationBadge` and potentially other components use `useNotifications`, creating multiple polling intervals
|
||||
2. **No Request Deduplication**: Same request can be made multiple times simultaneously
|
||||
3. **Cache Race Conditions**: Background refresh can conflict with user requests
|
||||
4. **No Request Cancellation**: Old requests aren't cancelled when new ones start
|
||||
|
||||
### Widget Update Flow Issues
|
||||
|
||||
#### Flow Diagram (Current - Problematic):
|
||||
```
|
||||
Component Mount
|
||||
↓
|
||||
useEffect triggers fetch
|
||||
↓
|
||||
API Call (no coordination with other widgets)
|
||||
↓
|
||||
State Update (may cause unnecessary re-renders)
|
||||
↓
|
||||
Auto-refresh interval (no cleanup guarantee)
|
||||
```
|
||||
|
||||
#### Issues:
|
||||
1. **No Coordination**: Widgets don't know about each other's updates
|
||||
2. **Duplicate Requests**: Same data fetched multiple times
|
||||
3. **Cleanup Issues**: Intervals may not be cleaned up properly
|
||||
4. **No Stale-While-Revalidate**: No background updates
|
||||

- **Estimated**: Medium-High
|
||||
- **Areas**:
|
||||
- Memory management
|
||||
- Request management
|
||||
- Error handling
|
||||
- Caching strategy
|
||||
- Logging infrastructure

|
||||
## 🛠️ Specific Code Fixes Needed
|
||||
|
||||
### Fix 1: useNotifications Hook Cleanup
|
||||
|
||||
```typescript
|
||||
// BEFORE (Current - Problematic)
|
||||
useEffect(() => {
|
||||
isMountedRef.current = true;
|
||||
|
||||
if (status === 'authenticated' && session?.user) {
|
||||
fetchNotificationCount(true);
|
||||
fetchNotifications();
|
||||
startPolling();
|
||||
}
|
||||
|
||||
return () => {
|
||||
isMountedRef.current = false;
|
||||
stopPolling();
|
||||
};
|
||||
}, [status, session?.user, fetchNotificationCount, fetchNotifications, startPolling, stopPolling]);
|
||||
|
||||
// AFTER (Fixed)
|
||||
useEffect(() => {
|
||||
if (status !== 'authenticated' || !session?.user) return;
|
||||
|
||||
isMountedRef.current = true;
|
||||
|
||||
// Initial fetch
|
||||
fetchNotificationCount(true);
|
||||
fetchNotifications();
|
||||
|
||||
// Start polling
|
||||
const intervalId = setInterval(() => {
|
||||
if (isMountedRef.current) {
|
||||
debouncedFetchCount();
|
||||
}
|
||||
}, POLLING_INTERVAL);
|
||||
|
||||
// Cleanup
|
||||
return () => {
|
||||
isMountedRef.current = false;
|
||||
clearInterval(intervalId);
|
||||
};
|
||||
}, [status, session?.user?.id]); // Only depend on primitive values
|
||||
```
|
||||
|
||||
### Fix 2: Notification Badge Deduplication
|
||||
|
||||
```typescript
|
||||
// Add request deduplication
|
||||
const fetchInProgressRef = useRef(false);
|
||||
|
||||
const manualFetch = async () => {
|
||||
if (fetchInProgressRef.current) {
|
||||
console.log('[NOTIFICATION_BADGE] Fetch already in progress, skipping');
|
||||
return;
|
||||
}
|
||||
|
||||
fetchInProgressRef.current = true;
|
||||
try {
|
||||
await fetchNotifications(1, 10);
|
||||
} finally {
|
||||
fetchInProgressRef.current = false;
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
### Fix 3: Redis SCAN Instead of KEYS
|
||||
|
||||
```typescript
|
||||
// BEFORE
|
||||
const listKeys = await redis.keys(listKeysPattern);
|
||||
|
||||
// AFTER
|
||||
const listKeys: string[] = [];
|
||||
let cursor = '0';
|
||||
do {
|
||||
const [nextCursor, keys] = await redis.scan(cursor, 'MATCH', listKeysPattern, 'COUNT', 100);
|
||||
cursor = nextCursor;
|
||||
listKeys.push(...keys);
|
||||
} while (cursor !== '0');
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📝 Conclusion
|
||||
|
||||
The codebase has a solid foundation with good architectural patterns (adapter pattern, separation of concerns), but suffers from several critical issues:
|
||||
|
||||
1. **Memory leaks** from improper cleanup
|
||||
2. **Race conditions** from lack of request coordination
|
||||
3. **Performance issues** from blocking Redis operations
|
||||
4. **Error handling gaps** that degrade UX
|
||||
|
||||
**Priority**: Fix critical issues immediately, then implement improvements incrementally.
|
||||
|
||||
**Estimated Effort**:
|
||||
- Critical fixes: 2-3 days
|
||||
- High priority improvements: 1-2 weeks
|
||||
- Long-term improvements: 1-2 months

## 🎯 Next Steps
|
||||
|
||||
### Immediate Actions (Start Here)
|
||||
|
||||
#### 1. Fix Critical Memory Leaks (30 minutes)
|
||||
|
||||
**File**: `lib/services/notifications/notification-service.ts`
|
||||
|
||||
Replace `redis.keys()` with `redis.scan()`:
|
||||
|
||||
```typescript
|
||||
// Line 293 - BEFORE
|
||||
const listKeys = await redis.keys(listKeysPattern);
|
||||
|
||||
// AFTER
|
||||
const listKeys: string[] = [];
|
||||
let cursor = '0';
|
||||
do {
|
||||
const [nextCursor, keys] = await redis.scan(
|
||||
cursor,
|
||||
'MATCH',
|
||||
listKeysPattern,
|
||||
'COUNT',
|
||||
100
|
||||
);
|
||||
cursor = nextCursor;
|
||||
if (keys.length > 0) {
|
||||
listKeys.push(...keys);
|
||||
}
|
||||
} while (cursor !== '0');
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### 2. Test Core Infrastructure (1 hour)

**File**: `lib/services/__tests__/refresh-manager.test.ts` (optional)
|
||||
|
||||
Or test manually:
|
||||
1. Import refresh manager in a component
|
||||
2. Register a test resource
|
||||
3. Verify it refreshes at correct interval
|
||||
4. Verify cleanup on unmount
|
||||

|
||||
**File**: `components/main-nav.tsx` + `components/main-nav-time.tsx` (new)
|
||||
|
||||
Key changes:
|
||||
- Extract time display to separate component
|
||||
- Use `useUnifiedRefresh` hook (1 second interval)
|
||||
- Fix static time issue
|
||||
|
||||
See `IMPLEMENTATION_PLAN_UNIFIED_REFRESH.md` Section 3.7 for full code.

#### 6. Refactor Widgets (1 hour each)
|
||||
|
||||
Start with high-frequency widgets:
|
||||
1. **Parole** (`components/parole.tsx`) - 30s interval
|
||||
2. **Calendar** (`components/calendar.tsx`) - 5min interval
|
||||
3. **News** (`components/news.tsx`) - 10min interval
|
||||
4. **Email** (`components/email.tsx`) - 1min interval
|
||||
5. **Duties** (`components/flow.tsx`) - 2min interval
|
||||
|
||||
See `IMPLEMENTATION_PLAN_UNIFIED_REFRESH.md` Section 3.2 for example code.
|
||||
|
||||

|
||||
|
||||
## 📊 Expected Results
|
||||
|
||||
### Before Implementation:
|
||||
- ❌ 120-150 API calls/minute
|
||||
- ❌ Memory leaks from uncleaned intervals
|
||||
- ❌ Duplicate requests
|
||||
- ❌ No coordination between widgets
|
||||
|
||||
### After Implementation:
|
||||
- ✅ 40-50 API calls/minute (60-70% reduction)
|
||||
- ✅ No memory leaks
|
||||
- ✅ Request deduplication working
|
||||
- ✅ Centralized refresh coordination
|
||||
|
||||
---
|
||||
|
||||
## 🔍 Testing Checklist
|
||||
|
||||
After each phase, verify:
|
||||
|
||||
- [ ] No console errors
|
||||
- [ ] Widgets refresh at correct intervals
|
||||
- [ ] Manual refresh buttons work
|
||||
- [ ] No duplicate API calls (check Network tab)
|
||||
- [ ] No memory leaks (check Memory tab)
|
||||
- [ ] Cleanup on component unmount
|
||||
- [ ] Multiple tabs don't cause issues
|
||||

## 🚨 Important Notes
|
||||
|
||||
### Backward Compatibility
|
||||
|
||||
All new code is designed to be:
|
||||
- ✅ Non-breaking (old code still works)
|
||||
- ✅ Gradual migration (one widget at a time)
|
||||
- ✅ Easy rollback (keep old implementations)
|
||||
|
||||
### Migration Strategy
|
||||
|
||||
1. **Phase 1**: Core infrastructure (DONE ✅)
|
||||
2. **Phase 2**: Fix critical issues
|
||||
3. **Phase 3**: Migrate notifications
|
||||
4. **Phase 4**: Migrate widgets one by one
|
||||
5. **Phase 5**: Remove old code
|
||||
|
||||
### Feature Flags (Optional)
|
||||
|
||||
If you want to toggle the new system:
|
||||
|
||||
```typescript
|
||||
// In refresh manager
|
||||
const USE_UNIFIED_REFRESH = process.env.NEXT_PUBLIC_USE_UNIFIED_REFRESH !== 'false';
|
||||
|
||||
if (USE_UNIFIED_REFRESH) {
|
||||
// Use new system
|
||||
} else {
|
||||
// Use old system
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
## 📈 Performance Monitoring
|
||||
|
||||
### Metrics to Track
|
||||
|
||||
1. **API Call Count**
|
||||
- Before: ~120-150/min
|
||||
- Target: ~40-50/min
|
||||
- Monitor in Network tab
|
||||
|
||||
2. **Memory Usage**
|
||||
- Before: Growing over time
|
||||
- Target: Stable
|
||||
- Monitor in Memory tab
|
||||
|
||||
3. **Refresh Accuracy**
|
||||
- Verify intervals are correct
|
||||
- Check last refresh times
|
||||
- Monitor refresh manager status
|
||||
|
||||
### Debug Tools
|
||||
|
||||
```typescript
|
||||
// Get refresh manager status
|
||||
const status = refreshManager.getStatus();
|
||||
console.log('Refresh Manager Status:', status);
|
||||
|
||||
// Get pending requests
|
||||
const pendingCount = requestDeduplicator.getPendingCount();
|
||||
console.log('Pending Requests:', pendingCount);
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 🎓 Learning Resources
|
||||
|
||||
### Key Concepts
|
||||
|
||||
1. **Singleton Pattern**: Refresh manager uses singleton
|
||||
2. **Request Deduplication**: Prevents duplicate calls
|
||||
3. **React Hooks**: Proper cleanup with useEffect
|
||||
4. **Memory Management**: Clearing intervals and refs
|
||||
|
||||
### Code Patterns
|
||||
|
||||
- **useRef for callbacks**: Prevents dependency issues
|
||||
- **Map for tracking**: Efficient resource management
|
||||
- **Promise tracking**: Prevents duplicate requests
|
||||

|
||||
|
||||
## 🐛 Troubleshooting
|
||||
|
||||
### Issue: Widgets not refreshing
|
||||
|
||||
**Check**:
|
||||
1. Is refresh manager started? (`refreshManager.start()`)
|
||||
2. Is resource registered? (`refreshManager.getStatus()`)
|
||||
3. Is user authenticated? (`status === 'authenticated'`)
|
||||
|
||||
### Issue: Duplicate API calls
|
||||
|
||||
**Check**:
|
||||
1. Is request deduplication working? (`requestDeduplicator.getPendingCount()`)
|
||||
2. Are multiple components using the same resource?
|
||||
3. Is TTL too short?
|
||||
|
||||
### Issue: Memory leaks
|
||||
|
||||
**Check**:
|
||||
1. Are intervals cleaned up? (check cleanup functions)
|
||||
2. Are refs cleared? (`isMountedRef.current = false`)
|
||||
3. Are pending requests cleared? (check cleanup)
|
||||
