Rate Limiting Implementation + +### Step 1: Configure Vercel KV + +In your Vercel dashboard: +1. Go to Storage → Create → KV Database +2. Copy the environment variables to `.env.local`: + +```env +KV_URL=redis://... +KV_REST_API_URL=https://... +KV_REST_API_TOKEN=... +``` + +### Step 2: Apply to API Routes + +**Example: `/api/chat/route.ts`** + +```typescript +import { withRateLimit, addRateLimitHeaders } from '@/lib/rate-limit'; +import { auth } from '@clerk/nextjs/server'; + +export async function POST(request: Request) { + // 1. Authenticate user + const { userId } = await auth(); + if (!userId) { + return new Response('Unauthorized', { status: 401 }); + } + + // 2. Check rate limit (generation tier for AI requests) + const rateLimitError = await withRateLimit(request, 'generation'); + if (rateLimitError) { + return rateLimitError; // Returns 429 with retry info + } + + // 3. Your existing logic + // ... AI generation code + + // 4. Return response (optional: add rate limit headers) + const response = new Response(JSON.stringify(data), { + status: 200, + headers: { 'Content-Type': 'application/json' }, + }); + + return response; +} +``` + +### Step 3: Apply to Other Routes + +Add rate limiting to these routes: +- ✅ `/api/chat` - generation tier +- ✅ `/api/enhanced-chat` - generation tier +- ✅ `/api/enhance-prompt` - api tier +- ✅ `/api/upload-image` - api tier +- ✅ `/api/chats` - api tier +- ✅ `/api/user/*` - api tier + +--- + +## 4.

Caching Layer + +### Step 1: Add Caching to Database Queries + +**Example: User subscription lookup** + +**Before:** +```typescript +// ❌ Direct DB query every time +async function getUserSubscription(userId: string) { + const subscription = await db.query.subscriptions.findFirst({ + where: eq(subscriptions.userId, userId), + }); + return subscription; +} +``` + +**After:** +```typescript +// ✅ Cache-aside pattern +import { cacheAside, CACHE_KEYS, CACHE_TTL } from '@/lib/cache'; + +async function getUserSubscription(userId: string) { + return cacheAside( + CACHE_KEYS.USER_SUBSCRIPTION(userId), + async () => { + const subscription = await db.query.subscriptions.findFirst({ + where: eq(subscriptions.userId, userId), + }); + return subscription; + }, + CACHE_TTL.USER_SUBSCRIPTION, + ); +} +``` + +### Step 2: Invalidate Cache on Updates + +```typescript +import { invalidateUserCache } from '@/lib/cache'; + +// After updating user subscription +await db.update(subscriptions) + .set({ planTier: 'pro' }) + .where(eq(subscriptions.userId, userId)); + +// Invalidate cache +await invalidateUserCache(userId); +``` + +### Step 3: Apply Caching to These Queries + +1. User subscription data +2. User usage statistics +3. Chat history +4. Chat messages +5. User profile + +--- + +## 6. CI/CD Pipeline + +### Step 1: Set Up GitHub Secrets + +Go to your GitHub repository → Settings → Secrets and variables → Actions + +Add these secrets: +- `VERCEL_TOKEN` - Get from Vercel → Settings → Tokens +- `VERCEL_ORG_ID` - From `.vercel/project.json` +- `VERCEL_PROJECT_ID` - From `.vercel/project.json` +- `DATABASE_URL` - Your production database URL + +### Step 2: Create Dev Branch + +```bash +git checkout -b dev +git push -u origin dev +``` + +### Step 3: Test the Pipeline + +```bash +# Make a change +echo "# Test" >> README.md +git add . +git commit -m "test: Trigger CI pipeline" +git push + +# Go to GitHub → Actions tab to see the pipeline running +``` + +### Step 4: Configure Branch Protection + +On GitHub: +1. Settings → Branches → Add rule +2. Branch name pattern: `main` +3. Check: + - ✅ Require status checks to pass + - ✅ Require branches to be up to date + - Select: `lint`, `test`, `build` +4. Save changes + +Now PRs to `main` must pass CI checks! + +--- + +## 7. Error Tracking + +### Step 1: Create Sentry Account + +1. Go to https://sentry.io +2. Create project (Next.js) +3. Copy DSN + +### Step 2: Add Environment Variables + +```env +# .env.local +SENTRY_DSN=https://xxx@sentry.io/xxx +NEXT_PUBLIC_SENTRY_DSN=https://xxx@sentry.io/xxx +SENTRY_AUTH_TOKEN=xxx +``` + +### Step 3: Initialize Sentry + +Run the Sentry wizard (optional, or use the configs provided): + +```bash +npx @sentry/wizard@latest -i nextjs +``` + +Or just use the configuration files already created: +- `sentry.client.config.ts` +- `sentry.server.config.ts` +- `sentry.edge.config.ts` + +### Step 4: Test Error Tracking + +Add a test button somewhere: + +```typescript + +``` + +Click it and check Sentry dashboard! + +### Step 5: Add Error Boundaries + +Create `src/app/error.tsx`: + +```typescript +'use client'; + +import * as Sentry from '@sentry/nextjs'; +import { useEffect } from 'react'; + +export default function Error({ + error, + reset, +}: { + error: Error & { digest?: string }; + reset: () => void; +}) { + useEffect(() => { + Sentry.captureException(error); + }, [error]); + + return ( +

Client Initialization + +Location: `src/lib/mem0-client.ts` + +```typescript +import MemoryClient from 'mem0ai'; + +const client = new MemoryClient({ apiKey: process.env.MEM0_API_KEY }); +``` + +The client is initialized as a singleton - created once and reused across requests. + +### 3. Data Storage Structure + +When a chat message is processed, we store **structured memory entries** in Mem0: + +#### Memory Entry Types + +1. **User Request** +```typescript +{ + role: 'user', + content: 'User requested: "create gaming thumbnail". Used reference image. Iteration on previous generation.' +} +``` + +2. **AI Response** +```typescript +{ + role: 'assistant', + content: 'Generated thumbnail: "gaming thumbnail". Model: gpt-4o-mini. Processing time: 3500ms.' +} +``` + +3. **Image Context** +```typescript +{ + role: 'system', + content: 'Image Management: User uploaded FIRST reference image. Prompt: "gaming thumbnail".' +} +``` + +4. **Iteration Patterns** +```typescript +{ + role: 'system', + content: 'Iteration Pattern: User is building on previous generation. Prefers incremental improvements.' +} +``` + +5. **Image Generation History** +```typescript +{ + role: 'system', + content: `Image Generation History: +1. Generated 5 min ago: "gaming thumbnail with neon colors" +2. Generated 3 min ago: "more vibrant with controller" + +Note: User can reference any of these previous generations.` +} +``` + +6. **User Preferences** +```typescript +{ + role: 'system', + content: 'User Preferences: Generation style: Iterative refinement. Input method: Text-based prompts. Total images in this chat: 3.' +} +``` + +7. **Usage Tracking** +```typescript +{ + role: 'system', + content: 'Usage Tracking: 1 thumbnail generation counted. Remaining: 7/10 (70% left). Usage is healthy.' +} +``` + +### 4. Metadata Structure + +Each memory includes metadata for filtering and organization: + +```typescript +{ + user_id: 'clerk_user_id', // Required - isolates memories by user + chat_id: 'chat_xyz123', // Optional - groups memories by chat + timestamp: '2025-01-20T10:30:00Z' // Debugging timestamp +} +``` + +### 5. Search and Retrieval + +**When a new message comes in:** + +```typescript +const memories = await searchMemory( + prompt, // User's current request + userId, // Clerk user ID + chatId, // Current chat ID + 10 // Limit to 10 most relevant memories +); +``` + +**Mem0 returns relevant memories based on semantic similarity to the prompt.** + +### 6. Context Building + +The retrieved memories are structured into categories: + +```typescript +// USER PREFERENCES +- Memories about user's preferences and patterns + +// RECENT REQUESTS +- Previous thumbnail generation requests + +// USAGE INFO +- Current usage limits and remaining credits + +// CURRENT SESSION +- Information about uploaded images + +// LAST GENERATION +- Details about the most recent generation + +// IMAGE GENERATION HISTORY +- Complete list of all images in this chat +``` + +This structured context is then passed to GPT-4o mini for reasoning. + +## API Endpoints + +### Test Endpoint + +**GET /api/test-mem0** +Tests Mem0 connectivity and data storage. + +```bash +curl http://localhost:3000/api/test-mem0 +``` + +Response: +```json +{ + "success": true, + "message": "Mem0 integration test completed successfully", + "results": { + "clientInitialized": true, + "memoryAdded": true, + "memoriesFound": 3, + "testUserId": "test_user_1234567890", + "testChatId": "test_chat_1234567890" + } +} +``` + +**POST /api/test-mem0** +Adds a custom test memory. + +```bash +curl -X POST http://localhost:3000/api/test-mem0 \ + -H "Content-Type: application/json" \ + -d '{ + "userId": "user_test_123", + "chatId": "chat_test_456", + "message": "Test memory entry" + }' +``` + +## Troubleshooting + +### No Data in Mem0 Dashboard + +**Common Issues:** + +1. **API Key Not Set** + ```bash + # Check if MEM0_API_KEY is set + echo $MEM0_API_KEY + ``` + +2. **Wrong API Key** + - Verify the key at https://app.mem0.ai/settings + +3. **API Call Failing Silently** + - Check server logs for error messages + - Look for `[MEM0]` prefixed log entries + +4. **Incorrect API Version** + - Current implementation uses `api_version: 'v2'` + - Verify this matches your Mem0 account settings + +### Debug Checklist + +1. **Check Environment Variables** + ```typescript + console.log('MEM0_API_KEY:', process.env.MEM0_API_KEY ? 'Set' : 'Not set'); + ``` + +2. **Test Mem0 Connection** + - Visit `/api/test-mem0` in your browser + - Check the response for errors + +3. **Check Server Logs** + - Look for Mem0-related log entries during chat requests + - Verify memory addition and search operations + +4. **Verify User ID** + - Ensure Clerk user ID is being passed correctly + - Check `getApiAuth()` returns valid user ID + +### Common Error Messages + +**Error:** `Cannot find module 'mem0ai'` +**Solution:** +```bash +npm install mem0ai +``` + +**Error:** `MEM0_API_KEY is not configured` +**Solution:** Add MEM0_API_KEY to your `.env.local` file + +**Error:** `Failed to add memory: 401 Unauthorized` +**Solution:** Check your API key is correct and active + +**Error:** `Failed to search memory: 429 Too Many Requests` +**Solution:** You've hit rate limits.

Structured Memory Entries + +✅ **Good:** +```typescript +{ + role: 'system', + content: 'User Preferences: Generation style: Iterative refinement. Input method: Uses reference images.' +} +``` + +❌ **Bad:** +```typescript +{ + role: 'system', + content: 'User did a thing' +} +``` + +### 2. Meaningful Metadata + +✅ **Good:** +```typescript +metadata: { + user_id: 'clerk_123abc', + chat_id: 'chat_xyz789', + timestamp: '2025-01-20T10:30:00Z' +} +``` + +❌ **Bad:** +```typescript +metadata: { + user_id: 'clerk_123abc' + // Missing chat_id for filtering +} +``` + +### 3. Error Handling + +Always wrap Mem0 calls in try-catch to prevent chat flow disruption: + +```typescript +try { + await addMemory(messages, userId, chatId); +} catch (error) { + console.error('Mem0 error:', error); + // Continue without memory - don't break chat +} +``` + +### 4. Async Operations + +Mem0 operations should be async and not block the response: + +```typescript +// Good - doesn't block response +(async () => { + await addMemory(messages, userId, chatId); +})(); + +return Response.json({ ... }); +``` + +## Monitoring + +### Log Patterns + +**Successful Addition:** +``` +📝 [MEM0] Adding 7 messages for user clerk_xyz, chat chat_abc + 1. user: User requested: "create thumbnail"... + 2. assistant: Generated thumbnail... + 3. system: Image Management... +✅ [MEM0] Memory stored successfully +📊 [MEM0] Result: { "results": [...] } +``` + +**Successful Search:** +``` +🔍 [MEM0] Searching memory... + User: clerk_xyz123 + Chat: chat_abc456 + Query: "create gaming thumbnail" + Limit: 10 +✅ [MEM0] Search completed: found 5 memories +📋 [MEM0] Sample results: + 1. {"memory": "User prefers vibrant colors", ...} +``` + +**Error:** +``` +❌ [MEM0] Failed to add memory +❌ [MEM0] Error details: Error: API key is invalid +❌ [MEM0] Error message: API key is invalid +``` + +## Performance Considerations + +- **Memory Storage:** Async, doesn't block response (~100-500ms) +- **Memory Search:** Blocks AI reasoning (~200-800ms) +- **Recommendation:** Keep search queries concise +- **Limits:** Check Mem0 plan for rate limits + +## Mem0 Dashboard + +Access your memories at: https://app.mem0.ai/memories + +**What you'll see:** +- All stored memories by user +- Metadata (user_id, chat_id, timestamp) +- Memory content +- Search and filter capabilities + +## Future Enhancements + +1. **Memory Pruning:** Auto-delete old memories (>30 days) +2. **Memory Summarization:** Compress old memories into summaries +3. **Cross-Chat Learning:** Learn preferences across all user chats +4. **Memory Analytics:** Track which memories are most useful +5. **Memory Export:** Allow users to download their memory history + +## Summary + +Mem0 provides the AI with **persistent memory** across conversations, enabling: +- Understanding of user preferences +- Awareness of previous generations +- Pattern recognition in user behavior +- Progressive improvement through learning +- Context-aware responses + +All memories are user-isolated, chat-grouped, and semantically searchable. diff --git a/docs/guides/QUICKSTART.md b/docs/guides/QUICKSTART.md new file mode 100644 index 0000000..6a97171 --- /dev/null +++ b/docs/guides/QUICKSTART.md @@ -0,0 +1,294 @@ +# Quick Start Guide - Renderly Improvements + +Get the improvements running in 15 minutes! + +--- + +## Prerequisites + +- Node.js 20+ +- PostgreSQL database (Neon) +- Vercel account +- Git + +--- + +## Step 1: Install Dependencies (2 min) + +```bash +# Install required packages +npm install @upstash/ratelimit @sentry/nextjs pino pino-pretty + +# Install dev dependencies +npm install -D vitest @vitest/ui @testing-library/react @testing-library/jest-dom jsdom +``` + +--- + +## Step 2: Database Indexes (1 min) + +```bash +# Apply the new database indexes +npx drizzle-kit push +``` + +**Verify:** +```sql +SELECT count(*) FROM pg_indexes WHERE schemaname = 'public'; +-- Should show 35+ indexes +``` + +✅ **Immediate Benefit:** Queries will be 10-50x faster! + +--- + +## Step 3: Set Up Caching (3 min) + +### Create Vercel KV Database + +1.
