+# Cloudflare Setup for Mylder Platform
+
+## Overview
+Cloudflare configuration for https://mylder.io - Next.js 16 frontend with self-hosted backend (Supabase, n8n) via Dokploy/Traefik.
+
+**VPS:** 149.102.155.84
+**Stack:** Next.js 16 → Traefik → Cloudflare CDN
+
+## DNS Configuration
+
+### Step 1: Add Domain to Cloudflare
+1. Cloudflare Dashboard → Add Site → mylder.io
+2. Update nameservers at domain registrar to Cloudflare's nameservers
+
+### Step 2: DNS Records
+
+| Type | Name | Target | Proxy Status | Notes |
+|------|------|--------|--------------|-------|
+| A | @ | 149.102.155.84 | Proxied (orange cloud) | Main site |
+| A | www | 149.102.155.84 | Proxied | WWW redirect |
+| A | dokploy | 149.102.155.84 | DNS Only (grey cloud) | Dokploy dashboard - skip CDN |
+| A | supabase | 149.102.155.84 | DNS Only | Supabase API - skip CDN |
+| A | n8n | 149.102.155.84 | DNS Only | n8n webhooks - skip CDN |
+| A | gitea | 149.102.155.84 | DNS Only | Git push/pull - skip CDN |
+| A | saas | 149.102.155.84 | DNS Only | Zulip chat - skip CDN |
+
+**Key Principle:**
+- **Proxied (CDN):** Frontend, static assets, public content
+- **DNS Only:** Admin tools, APIs with authentication, real-time services
+
+### Step 3: Subdomain Wildcard (Optional)
+If you need dynamic subdomains (e.g., tenant.mylder.io):
+```
+CNAME * @ (Proxied)
+```
+
+## SSL/TLS Settings
+
+### Encryption Mode: Full (Strict)
+**Path:** SSL/TLS → Overview → Full (strict)
+
+**Why:** Traefik already provides Let's Encrypt certificates. Full (strict) ensures end-to-end encryption:
+```
+Browser → Cloudflare (encrypted) → Traefik (encrypted) → App
+```
+
+### Edge Certificates
+**Path:** SSL/TLS → Edge Certificates
+
+- **Always Use HTTPS:** ON
+- **Minimum TLS Version:** 1.2
+- **Opportunistic Encryption:** ON
+- **TLS 1.3:** ON
+- **Automatic HTTPS Rewrites:** ON
+- **Certificate Transparency Monitoring:** ON
+
+### Origin Server
+**Path:** SSL/TLS → Origin Server
+
+No action needed - Traefik manages Let's Encrypt certificates automatically.
+
+## Caching Rules
+
+### Default Cache Levels
+**Path:** Caching → Configuration
+
+- **Caching Level:** Standard
+- **Browser Cache TTL:** Respect Existing Headers
+- **Always Online:** ON (serves stale content if origin is down)
+
+### Cache Rules for Next.js
+**Path:** Rules → Page Rules (legacy) or Cache Rules (new)**
+
+#### Rule 1: Static Assets (Aggressive Caching)
+```
+URL Pattern: mylder.io/_next/static/*
+Settings:
+  - Cache Level: Cache Everything
+  - Edge Cache TTL: 1 year
+  - Browser Cache TTL: 1 year
+```
+
+#### Rule 2: Images (Smart Caching)
+```
+URL Pattern: mylder.io/_next/image/*
+Settings:
+  - Cache Level: Cache Everything
+  - Edge Cache TTL: 30 days
+  - Browser Cache TTL: 7 days
+```
+
+#### Rule 3: API Routes (No Cache)
+```
+URL Pattern: mylder.io/api/*
+Settings:
+  - Cache Level: Bypass
+```
+
+#### Rule 4: Dynamic Pages (Smart Cache)
+```
+URL Pattern: mylder.io/*
+Settings:
+  - Cache Level: Standard
+  - Edge Cache TTL: 2 hours
+  - Browser Cache TTL: 30 minutes
+```
+
+### Next.js Cache Headers
+Ensure your Next.js app sets proper headers:
+
+```typescript
+// next.config.ts
+const nextConfig = {
+  async headers() {
+    return [
+      {
+        source: '/_next/static/:path*',
+        headers: [
+          {
+            key: 'Cache-Control',
+            value: 'public, max-age=31536000, immutable',
+          },
+        ],
+      },
+      {
+        source: '/_next/image/:path*',
+        headers: [
+          {
+            key: 'Cache-Control',
+            value: 'public, max-age=2592000, stale-while-revalidate=86400',
+          },
+        ],
+      },
+    ];
+  },
+};
+```
+
+### Cache Purge Strategy
+**Path:** Caching → Configuration → Purge Cache
+
+- **On Deploy:** Purge Everything (via API or Dashboard)
+- **On Content Update:** Purge by Tag/URL
+- **Emergency:** Purge Everything button
+
+**API Purge (for CI/CD):**
+```bash
+curl -X POST "https://api.cloudflare.com/client/v4/zones/{zone_id}/purge_cache" \
+  -H "Authorization: Bearer {api_token}" \
+  -H "Content-Type: application/json" \
+  --data '{"purge_everything":true}'
+```
+
+## Speed Optimization
+
+### Auto Minify
+**Path:** Speed → Optimization
+
+- **JavaScript:** ON
+- **CSS:** ON
+- **HTML:** ON
+
+### Brotli Compression
+**Path:** Speed → Optimization
+
+- **Brotli:** ON (better than gzip)
+
+### Early Hints
+**Path:** Speed → Optimization
+
+- **Early Hints:** ON (preload critical resources)
+
+### Rocket Loader
+**Path:** Speed → Optimization
+
+- **Rocket Loader:** OFF (can conflict with React hydration)
+
+### Image Optimization
+**Path:** Speed → Optimization → Image Resizing
+
+- **Polish:** Lossless (or Lossy for smaller files)
+- **Mirage:** ON (lazy loading for mobile)
+- **Image Resizing:** Available on Pro+ plan
+
+**Next.js Image Optimization:**
+```typescript
+// next.config.ts
+const nextConfig = {
+  images: {
+    formats: ['image/avif', 'image/webp'],
+    deviceSizes: [640, 750, 828, 1080, 1200, 1920, 2048],
+    imageSizes: [16, 32, 48, 64, 96, 128, 256, 384],
+    minimumCacheTTL: 2592000, // 30 days
+  },
+};
+```
+
+## Security Settings
+
+### SSL/TLS
+- **Always Use HTTPS:** ON
+- **HSTS:** Enable with max-age=31536000, includeSubDomains
+
+### Firewall (WAF)
+**Path:** Security → WAF
+
+#### Managed Rules (Free Tier)
+- **Cloudflare Managed Ruleset:** ON
+- **OWASP Core Ruleset:** ON
+
+#### Rate Limiting (Pro+ Plan)
+```yaml
+Rule: API Protection
+If: Request URL contains /api/
+Then: Rate limit 100 requests per minute per IP
+```
+
+#### Bot Fight Mode (Free)
+**Path:** Security → Bots
+
+- **Bot Fight Mode:** ON
+- **Super Bot Fight Mode:** Pro+ plan
+
+### Security Level
+**Path:** Security → Settings
+
+- **Security Level:** Medium (balance between security and UX)
+
+### Challenge Passage
+**Path:** Security → Settings
+
+- **Challenge Passage:** 30 minutes
+
+## Network Settings
+
+### HTTP/2 & HTTP/3
+**Path:** Network
+
+- **HTTP/2:** ON (default)
+- **HTTP/3 (QUIC):** ON (faster connections)
+- **0-RTT Connection Resumption:** ON
+
+### WebSockets
+**Path:** Network
+
+- **WebSockets:** ON (required for real-time features)
+
+### gRPC
+**Path:** Network
+
+- **gRPC:** OFF (not needed for standard Next.js)
+
+## Analytics & Monitoring
+
+### Web Analytics
+**Path:** Analytics & Logs → Web Analytics
+
+- Enable Cloudflare Web Analytics (privacy-friendly, no cookie banner needed)
+
+### Performance Monitoring
+- **Core Web Vitals:** Track LCP, FID, CLS
+- **Page Load Time:** Monitor at edge
+
+### Real User Monitoring (RUM)
+Add Cloudflare Zaraz or custom analytics:
+```html
+<!-- Cloudflare Web Analytics -->
+<script defer src='https://static.cloudflareinsights.com/beacon.min.js'
+        data-cf-beacon='{"token": "YOUR_TOKEN"}'></script>
+```
+
+## Subdomain Configuration
+
+Since you have multiple services, ensure proper routing:
+
+### Traefik Labels (Dokploy Docker Compose)
+```yaml
+services:
+  app:
+    labels:
+      - "traefik.enable=true"
+      - "traefik.http.routers.mylder.rule=Host(`mylder.io`) || Host(`www.mylder.io`)"
+      - "traefik.http.routers.mylder.tls=true"
+      - "traefik.http.routers.mylder.tls.certresolver=letsencrypt"
+```
+
+### WWW Redirect (Cloudflare)
+**Path:** Rules → Redirect Rules
+
+```
+If: Hostname equals www.mylder.io
+Then: Redirect to https://mylder.io$1 (301 permanent)
+```
+
+## Testing Checklist
+
+### DNS Propagation
+```bash
+dig mylder.io
+nslookup mylder.io
+```
+
+### SSL Certificate
+```bash
+curl -I https://mylder.io
+# Check for: HTTP/2 200, cf-cache-status header
+```
+
+### Cache Verification
+```bash
+curl -I https://mylder.io/_next/static/[hash]/[file].js
+# Look for: cf-cache-status: HIT
+```
+
+### Performance
+```bash
+# Lighthouse
+npx lighthouse https://mylder.io --view
+
+# WebPageTest
+# Visit https://www.webpagetest.org
+```
+
+## Troubleshooting
+
+### 521 Error (Web Server Down)
+- Check Traefik is running: `docker ps | grep traefik`
+- Check Dokploy deployment status
+
+### 522 Error (Connection Timed Out)
+- Verify firewall allows Cloudflare IPs
+- Check VPS security groups
+
+### 525 Error (SSL Handshake Failed)
+- Ensure SSL/TLS mode is "Full (strict)"
+- Verify Traefik has valid Let's Encrypt certificate
+
+### Cache Not Working
+- Check Cache-Control headers in response
+- Verify Page Rules are active
+- Clear Cloudflare cache and test
+
+### Mixed Content Warnings
+- Enable "Automatic HTTPS Rewrites"
+- Update hardcoded http:// URLs to https://
+
+## Cost Optimization
+
+### Free Plan Limits
+- 100k requests/day (~3M/month)
+- Unlimited bandwidth
+- Basic DDoS protection
+- Shared SSL certificate
+- 3 Page Rules
+
+### When to Upgrade to Pro ($20/month)
+- Need more than 3 Page Rules
+- Want Image Optimization (Polish, Mirage)
+- Need custom SSL certificate
+- Require advanced WAF rules
+- Want priority support
+
+### Enterprise Features (for future)
+- Cloudflare Workers (serverless at edge)
+- Load Balancing
+- Argo Smart Routing
+- Custom WAF rules
+
+## Next Steps
+
+1. **Immediate:** DNS + SSL/TLS setup
+2. **Week 1:** Caching rules + performance testing
+3. **Month 1:** Monitor analytics, tune cache rules
+4. **Quarter 1:** Consider Workers for edge logic (see cloudflare-workers-roadmap.md)

+# Cloudflare Workers Roadmap for Mylder
+
+## Overview
+Edge computing strategy for Mylder platform using Cloudflare Workers, R2, D1, and KV.
+
+**Philosophy:** Move compute closer to users, reduce VPS load, improve UX with sub-100ms responses.
+
+## Current Architecture vs Edge-First
+
+### Current (VPS-Centric)
+```
+User → Cloudflare CDN → VPS (149.102.155.84)
+                          ├── Next.js (Frontend)
+                          ├── Supabase (Auth, DB)
+                          ├── n8n (Automation)
+                          └── Dokploy (Orchestration)
+```
+
+### Future (Edge-First)
+```
+User → Cloudflare Workers (Edge Logic)
+       ├── Static Assets (CDN)
+       ├── Edge Auth (Workers + KV)
+       ├── Edge API (Workers + D1)
+       └── Origin (VPS for heavy compute)
+           ├── Supabase (Primary DB)
+           └── n8n (Automation)
+```
+
+## Workers Use Cases
+
+### 1. Edge Authentication (Priority: High)
+
+**Problem:** Every auth check hits VPS → Supabase (100-300ms)
+**Solution:** Cache JWT validation at edge
+
+```typescript
+// workers/auth-edge.ts
+export default {
+  async fetch(request: Request, env: Env): Promise<Response> {
+    const token = request.headers.get('Authorization')?.split('Bearer ')[1];
+    if (!token) return new Response('Unauthorized', { status: 401 });
+
+    // Check KV cache for user session
+    const cached = await env.SESSIONS.get(token);
+    if (cached) {
+      return new Response(cached, {
+        headers: { 'X-Auth-Source': 'edge-cache' }
+      });
+    }
+
+    // Fallback to Supabase origin
+    const response = await fetch('https://supabase.mylder.io/auth/v1/user', {
+      headers: { Authorization: `Bearer ${token}` }
+    });
+
+    if (response.ok) {
+      const user = await response.text();
+      await env.SESSIONS.put(token, user, { expirationTtl: 3600 }); // 1 hour
+      return new Response(user, {
+        headers: { 'X-Auth-Source': 'origin' }
+      });
+    }
+
+    return response;
+  }
+};
+```
+
+**Benefits:**
+- Auth checks: 300ms → 10ms (30x faster)
+- Reduced Supabase load
+- Better UX for logged-in users
+
+**Trade-offs:**
+- Session invalidation complexity
+- KV storage costs ($0.50/1M reads)
+
+### 2. API Rate Limiting (Priority: High)
+
+**Problem:** DDoS/abuse protection on VPS is resource-intensive
+**Solution:** Rate limit at edge before hitting origin
+
+```typescript
+// workers/rate-limiter.ts
+import { RateLimiter } from '@cloudflare/workers-rate-limiter';
+
+export default {
+  async fetch(request: Request, env: Env): Promise<Response> {
+    const limiter = new RateLimiter({
+      namespace: env.RATE_LIMIT,
+      // 100 requests per 60 seconds per IP
+      limit: 100,
+      period: 60,
+    });
+
+    const ip = request.headers.get('CF-Connecting-IP') || 'unknown';
+    const { success } = await limiter.limit({ key: ip });
+
+    if (!success) {
+      return new Response('Rate limit exceeded', {
+        status: 429,
+        headers: { 'Retry-After': '60' }
+      });
+    }
+
+    // Forward to origin
+    return fetch(request);
+  }
+};
+```
+
+**Benefits:**
+- Block abuse before it hits VPS
+- Per-IP, per-user, per-endpoint limits
+- 0ms latency overhead
+
+**Use Cases:**
+- `/api/*` endpoints
+- Login attempts
+- Form submissions
+- Search queries
+
+### 3. A/B Testing at Edge (Priority: Medium)
+
+**Problem:** Client-side A/B testing causes layout shift (poor CLS)
+**Solution:** Server-side rendering with edge variants
+
+```typescript
+// workers/ab-test.ts
+export default {
+  async fetch(request: Request, env: Env): Promise<Response> {
+    const url = new URL(request.url);
+
+    // Check existing variant
+    let variant = request.headers.get('Cookie')?.match(/variant=([AB])/)?.[1];
+
+    if (!variant) {
+      // Assign 50/50 split
+      variant = Math.random() < 0.5 ? 'A' : 'B';
+    }
+
+    // Rewrite request to origin with variant
+    const originUrl = `${url.origin}${url.pathname}?variant=${variant}`;
+    const response = await fetch(originUrl, request);
+
+    // Set variant cookie
+    const headers = new Headers(response.headers);
+    headers.set('Set-Cookie', `variant=${variant}; Path=/; Max-Age=2592000`);
+
+    return new Response(response.body, {
+      status: response.status,
+      headers
+    });
+  }
+};
+```
+
+**Benefits:**
+- No layout shift (CLS = 0)
+- Instant variant assignment
+- Analytics at edge
+
+**Use Cases:**
+- Landing page variants
+- Pricing page tests
+- Feature flags
+
+### 4. Edge Personalization (Priority: Medium)
+
+**Problem:** Generic content for all users (low engagement)
+**Solution:** Geo/device-specific content at edge
+
+```typescript
+// workers/personalize.ts
+export default {
+  async fetch(request: Request, env: Env): Promise<Response> {
+    const country = request.cf?.country as string;
+    const device = request.headers.get('User-Agent')?.includes('Mobile')
+      ? 'mobile'
+      : 'desktop';
+
+    // Fetch base HTML from origin
+    const response = await fetch(request);
+    const html = await response.text();
+
+    // Inject personalized content
+    const personalized = html
+      .replace('{{COUNTRY}}', country)
+      .replace('{{DEVICE}}', device)
+      .replace('{{CURRENCY}}', getCurrency(country));
+
+    return new Response(personalized, {
+      headers: {
+        'Content-Type': 'text/html',
+        'Cache-Control': 'public, max-age=60, s-maxage=3600',
+        'Vary': 'CF-IPCountry, User-Agent'
+      }
+    });
+  }
+};
+
+function getCurrency(country: string): string {
+  const map: Record<string, string> = {
+    US: 'USD', GB: 'GBP', EU: 'EUR', DK: 'DKK'
+  };
+  return map[country] || 'USD';
+}
+```
+
+**Benefits:**
+- Geo-specific content (currency, language)
+- Device-optimized markup
+- Sub-50ms personalization
+
+**Use Cases:**
+- Pricing display
+- Content localization
+- Feature availability
+
+### 5. Image Optimization & Resizing (Priority: Low)
+
+**Problem:** Next.js Image Optimization on VPS is CPU-intensive
+**Solution:** Cloudflare Images or Workers + R2
+
+```typescript
+// workers/image-optimize.ts
+export default {
+  async fetch(request: Request, env: Env): Promise<Response> {
+    const url = new URL(request.url);
+    const imagePath = url.pathname.replace('/img/', '');
+
+    // Parse resize params
+    const width = url.searchParams.get('w') || '1920';
+    const quality = url.searchParams.get('q') || '80';
+    const format = url.searchParams.get('f') || 'webp';
+
+    // Fetch from R2
+    const object = await env.IMAGES.get(imagePath);
+    if (!object) return new Response('Not Found', { status: 404 });
+
+    // Resize at edge (requires paid Workers plan)
+    const resized = await fetch(`https://mylder.io/cdn-cgi/image/width=${width},quality=${quality},format=${format}/${imagePath}`);
+
+    return new Response(resized.body, {
+      headers: {
+        'Content-Type': `image/${format}`,
+        'Cache-Control': 'public, max-age=31536000, immutable'
+      }
+    });
+  }
+};
+```
+
+**Benefits:**
+- Offload VPS CPU
+- Auto WebP/AVIF conversion
+- Responsive images on-demand
+
+**Trade-offs:**
+- Requires Cloudflare Images ($5/month + $1/100k)
+- Or R2 storage ($0.015/GB/month)
+
+### 6. Edge API Caching (Priority: Medium)
+
+**Problem:** Repeated API calls for same data
+**Solution:** Smart caching with stale-while-revalidate
+
+```typescript
+// workers/api-cache.ts
+export default {
+  async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
+    const cache = caches.default;
+    const cacheKey = new Request(request.url, request);
+
+    // Check cache
+    let response = await cache.match(cacheKey);
+    if (response) {
+      const age = Date.now() - new Date(response.headers.get('Date')!).getTime();
+
+      // If stale (>60s), revalidate in background
+      if (age > 60000) {
+        ctx.waitUntil(revalidate(request, cache, cacheKey));
+      }
+
+      return response;
+    }
+
+    // Fetch from origin
+    response = await fetch(request);
+
+    // Cache for 5 minutes
+    const cached = new Response(response.body, response);
+    cached.headers.set('Cache-Control', 'public, max-age=300, stale-while-revalidate=3600');
+    ctx.waitUntil(cache.put(cacheKey, cached));
+
+    return response;
+  }
+};
+
+async function revalidate(request: Request, cache: Cache, key: Request) {
+  const fresh = await fetch(request);
+  await cache.put(key, fresh.clone());
+}
+```
+
+**Benefits:**
+- API responses: 200ms → 10ms
+- Stale content served instantly
+- Background revalidation
+
+**Use Cases:**
+- Public API endpoints
+- User profiles
+- Content feeds
+
+## Cloudflare R2 (Object Storage)
+
+### Use Cases for R2
+
+**What:** S3-compatible object storage at edge (no egress fees)
+
+#### 1. User Uploads
+```typescript
+// Store user avatars, documents
+await env.UPLOADS.put(`users/${userId}/avatar.jpg`, file);
+```
+
+**Benefits:**
+- $0.015/GB/month (10x cheaper than S3)
+- No egress fees (free downloads)
+- Global CDN distribution
+
+**When to Use:**
+- User-generated content (avatars, documents)
+- Static assets (fonts, icons)
+- Media files (videos, audio)
+
+**When NOT to Use:**
+- Frequent small writes (use D1 instead)
+- Sub-10MB total storage (use KV instead)
+
+#### 2. Static Asset Hosting
+```typescript
+// Move _next/static/* to R2
+const asset = await env.STATIC_ASSETS.get(path);
+return new Response(asset.body, {
+  headers: { 'Cache-Control': 'public, max-age=31536000, immutable' }
+});
+```
+
+**Benefits:**
+- Reduce VPS storage needs
+- Faster global distribution
+- Immutable content = perfect cache
+
+#### 3. Backup Storage
+```typescript
+// Daily Supabase backups to R2
+await env.BACKUPS.put(`supabase-${date}.sql.gz`, backup);
+```
+
+## Cloudflare D1 (Edge Database)
+
+### Use Cases for D1
+
+**What:** SQLite at edge (sub-10ms queries globally)
+
+#### 1. Edge Metadata
+```typescript
+// Store user preferences, feature flags
+const db = env.DB;
+const result = await db.prepare(
+  'SELECT theme, locale FROM user_prefs WHERE user_id = ?'
+).bind(userId).first();
+```
+
+**Benefits:**
+- Read latency: 100ms (Supabase) → 5ms (D1)
+- No VPS load for reads
+- SQL interface (familiar)
+
+**When to Use:**
+- Read-heavy data (user settings, configs)
+- Small datasets (<1GB)
+- Geo-distributed reads
+
+**When NOT to Use:**
+- Write-heavy workloads (D1 eventual consistency)
+- Complex joins (use Supabase instead)
+- Primary data storage (Supabase is source of truth)
+
+#### 2. Analytics/Metrics
+```typescript
+// Store page views, click events
+await db.prepare(
+  'INSERT INTO analytics (page, user_id, timestamp) VALUES (?, ?, ?)'
+).bind(page, userId, Date.now()).run();
+```
+
+**Benefits:**
+- High-volume writes
+- Real-time aggregations
+- No Supabase quota impact
+
+#### 3. Feature Flags
+```typescript
+// Enable/disable features per user
+const flags = await db.prepare(
+  'SELECT * FROM feature_flags WHERE active = 1'
+).all();
+```
+
+### D1 vs Supabase Decision Matrix
+
+| Feature | D1 (Edge) | Supabase (VPS) |
+|---------|-----------|----------------|
+| Read Latency | 5-10ms | 100-300ms |
+| Write Latency | 50-100ms | 100-300ms |
+| Consistency | Eventual | Strong |
+| Storage Limit | 1GB | 8GB+ |
+| Cost | Free (5M reads/day) | Included in VPS |
+| Use Case | Cached metadata | Primary data |
+
+**Strategy:** D1 = edge cache, Supabase = source of truth
+
+## Cloudflare KV (Key-Value Store)
+
+### Use Cases for KV
+
+**What:** Global key-value store (sub-1ms reads)
+
+#### 1. Session Storage
+```typescript
+await env.SESSIONS.put(sessionId, userData, { expirationTtl: 3600 });
+```
+
+**Benefits:**
+- Fastest storage option (<1ms reads)
+- Auto-expiration (TTL)
+- Global replication
+
+**Cost:** $0.50/1M reads, $5/1M writes (generous free tier)
+
+#### 2. Configuration/Secrets
+```typescript
+const apiKey = await env.CONFIG.get('stripe_public_key');
+```
+
+#### 3. Rate Limit Counters
+```typescript
+const count = await env.RATE_LIMIT.get(ip);
+await env.RATE_LIMIT.put(ip, count + 1, { expirationTtl: 60 });
+```
+
+## Implementation Roadmap
+
+### Phase 1: Foundation (Month 1)
+**Goal:** Basic edge infrastructure
+
+- [ ] Set up Cloudflare Workers project
+- [ ] Deploy edge auth validator (Worker + KV)
+- [ ] Implement rate limiting for `/api/*`
+- [ ] Migrate static assets to R2
+- [ ] Monitor performance impact
+
+**Success Metrics:**
+- Auth latency: <20ms (p95)
+- Static asset cache hit rate: >95%
+- VPS CPU load: -20%
+
+### Phase 2: Optimization (Month 2-3)
+**Goal:** Performance wins
+
+- [ ] Deploy A/B testing worker
+- [ ] Implement edge personalization
+- [ ] Set up D1 for user preferences
+- [ ] Create stale-while-revalidate API cache
+- [ ] Image optimization via R2 + Workers
+
+**Success Metrics:**
+- LCP: <1.5s (p75)
+- API latency: -50% for cached endpoints
+- Global availability: 99.9%
+
+### Phase 3: Advanced (Month 4+)
+**Goal:** Edge-first architecture
+
+- [ ] Move session management to edge (D1 + KV)
+- [ ] Implement edge analytics (D1)
+- [ ] Deploy feature flags system (D1)
+- [ ] Create edge API gateway
+- [ ] Multi-region failover
+
+**Success Metrics:**
+- Edge request ratio: >70%
+- Origin load: -60%
+- Global latency: <100ms (p95)
+
+## Cost Analysis
+
+### Free Tier Limits
+- **Workers:** 100k requests/day
+- **KV:** 100k reads/day, 1k writes/day
+- **R2:** 10GB storage, 1M reads/month
+- **D1:** 5M reads/day, 100k writes/day
+
+### Paid Costs (Estimated for 1M users/month)
+
+| Service | Usage | Cost/Month |
+|---------|-------|------------|
+| Workers | 100M requests | $5 (bundled) |
+| KV | 50M reads | $25 |
+| R2 | 100GB storage + 500M reads | $1.50 |
+| D1 | Included in Workers | $0 |
+| **Total** | | **~$30/month** |
+
+**ROI:** Potential to downgrade VPS ($30/month savings) → break even
+
+## Anti-Patterns to Avoid
+
+### 1. Over-Caching
+**Bad:** Cache everything at edge for 24 hours
+**Good:** Cache static assets long, dynamic content short
+
+### 2. Edge as Primary DB
+**Bad:** Store all user data in D1
+**Good:** D1 = cache, Supabase = source of truth
+
+### 3. Synchronous Edge-Origin Calls
+**Bad:** Worker → fetch origin → wait → respond
+**Good:** Serve stale, revalidate in background
+
+### 4. Ignoring Cold Starts
+**Bad:** Assume Workers are instant
+**Good:** Optimize bundle size (<1MB), minimize dependencies
+
+### 5. Complex Business Logic at Edge
+**Bad:** Move entire Next.js app to Workers
+**Good:** Keep heavy compute on VPS, edge for lightweight tasks
+
+## Monitoring & Debugging
+
+### Workers Analytics
+**Dashboard:** Workers & Pages → Analytics
+
+- Request volume
+- Success rate (2xx/3xx/4xx/5xx)
+- CPU time (p50, p95, p99)
+- Error logs
+
+### Tail Workers (Real-Time Logs)
+```bash
+wrangler tail mylder-auth-edge
+```
+
+### Custom Metrics
+```typescript
+// workers/metrics.ts
+export default {
+  async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
+    const start = Date.now();
+    const response = await fetch(request);
+    const duration = Date.now() - start;
+
+    // Log to D1 analytics
+    ctx.waitUntil(
+      env.ANALYTICS.prepare(
+        'INSERT INTO metrics (endpoint, duration, status) VALUES (?, ?, ?)'
+      ).bind(request.url, duration, response.status).run()
+    );
+
+    return response;
+  }
+};
+```
+
+## Next Steps
+
+1. **Prototype:** Deploy simple edge auth worker (1 day)
+2. **Measure:** Compare edge vs origin performance (1 week)
+3. **Iterate:** Expand to rate limiting, A/B testing (1 month)
+4. **Optimize:** Move 70%+ traffic to edge (3 months)

+FID: ~150ms → Target: <100ms
+CLS: ~0.15 → Target: <0.1
+TTFB: ~800ms → Target: <600ms (edge caching)
+```
+
+### Measurement Tools
+
+#### 1. Real User Monitoring (RUM)
+```typescript
+// app/layout.tsx
+import { SpeedInsights } from '@vercel/speed-insights/next';
+import { Analytics } from '@vercel/analytics/react';
+
+export default function RootLayout({ children }) {
+  return (
+    <html>
+      <body>
+        {children}
+        <SpeedInsights />
+        <Analytics />
+      </body>
+    </html>
+  );
+}
+```
+
+**Alternative:** Cloudflare Web Analytics (privacy-friendly, no cookies)
+```html
+<script defer src='https://static.cloudflareinsights.com/beacon.min.js'
+        data-cf-beacon='{"token": "YOUR_TOKEN"}'></script>
+```
+
+#### 2. Lab Testing
+```bash
+# Lighthouse (local)
+npx lighthouse https://mylder.io --view
+
+# WebPageTest (global)
+# https://www.webpagetest.org
+
+# Chrome DevTools
+# DevTools → Performance → Record → Analyze
+```
+
+#### 3. Continuous Monitoring
+```bash
+# Lighthouse CI (in CI/CD pipeline)
+npm install -g @lhci/cli
+lhci autorun --collect.url=https://mylder.io
+```
+
+## Next.js Optimization Settings
+
+### 1. Production Build Configuration
+
+```typescript
+// next.config.ts
+import type { NextConfig } from 'next';
+
+const nextConfig: NextConfig = {
+  // Enable React strict mode for better error handling
+  reactStrictMode: true,
+
+  // Optimize bundle size
+  swcMinify: true,
+
+  // Compress output
+  compress: true,
+
+  // Optimize images
+  images: {
+    formats: ['image/avif', 'image/webp'],
+    deviceSizes: [640, 750, 828, 1080, 1200, 1920],
+    imageSizes: [16, 32, 48, 64, 96, 128, 256],
+    minimumCacheTTL: 2592000, // 30 days
+    dangerouslyAllowSVG: false,
+    contentDispositionType: 'attachment',
+    remotePatterns: [
+      {
+        protocol: 'https',
+        hostname: 'supabase.mylder.io',
+        pathname: '/storage/v1/object/**',
+      },
+    ],
+  },
+
+  // Optimize fonts (automatic optimization)
+  optimizeFonts: true,
+
+  // Experimental features
+  experimental: {
+    // Optimize CSS
+    optimizeCss: true,
+    // Tree shaking for smaller bundles
+    optimizePackageImports: ['@radix-ui/react-icons', 'lucide-react'],
+  },
+
+  // Custom headers for caching
+  async headers() {
+    return [
+      {
+        source: '/:path*',
+        headers: [
+          {
+            key: 'X-DNS-Prefetch-Control',
+            value: 'on',
+          },
+          {
+            key: 'X-Frame-Options',
+            value: 'SAMEORIGIN',
+          },
+        ],
+      },
+      {
+        source: '/_next/static/:path*',
+        headers: [
+          {
+            key: 'Cache-Control',
+            value: 'public, max-age=31536000, immutable',
+          },
+        ],
+      },
+      {
+        source: '/_next/image/:path*',
+        headers: [
+          {
+            key: 'Cache-Control',
+            value: 'public, max-age=2592000, stale-while-revalidate=86400',
+          },
+        ],
+      },
+    ];
+  },
+};
+
+export default nextConfig;
+```
+
+### 2. Bundle Analyzer
+```bash
+# Install
+npm install -D @next/bundle-analyzer
+
+# next.config.ts
+import bundleAnalyzer from '@next/bundle-analyzer';
+
+const withBundleAnalyzer = bundleAnalyzer({
+  enabled: process.env.ANALYZE === 'true',
+});
+
+export default withBundleAnalyzer(nextConfig);
+
+# Run analysis
+ANALYZE=true npm run build
+```
+
+**Target:** Total bundle size <500KB (gzipped)
+
+### 3. Code Splitting Strategies
+
+#### Dynamic Imports
+```typescript
+// app/dashboard/page.tsx
+import dynamic from 'next/dynamic';
+
+// Lazy load heavy components
+const HeavyChart = dynamic(() => import('@/components/HeavyChart'), {
+  loading: () => <ChartSkeleton />,
+  ssr: false, // Client-side only if needed
+});
+
+export default function Dashboard() {
+  return <HeavyChart data={data} />;
+}
+```
+
+#### Route-Based Splitting
+```typescript
+// Automatic with App Router
+app/
+  dashboard/      # Separate chunk
+  settings/       # Separate chunk
+  (marketing)/    # Separate chunk (route group)
+```
+
+#### Vendor Splitting
+```typescript
+// next.config.ts
+experimental: {
+  optimizePackageImports: [
+    '@radix-ui/react-icons',
+    'lucide-react',
+    'date-fns',
+  ],
+},
+```
+
+### 4. Server Components (Default)
+```typescript
+// app/page.tsx (Server Component by default)
+export default async function Home() {
+  // Fetch at build time or request time
+  const data = await fetch('https://api.mylder.io/data', {
+    next: { revalidate: 3600 } // ISR: 1 hour cache
+  });
+
+  return <div>{/* No client-side JS for this component */}</div>;
+}
+```
+
+**Benefits:**
+- 0KB JavaScript sent to client
+- Faster initial page load
+- Better SEO
+
+### 5. Client Components (Opt-In)
+```typescript
+// components/InteractiveButton.tsx
+'use client';
+
+import { useState } from 'react';
+
+export default function InteractiveButton() {
+  const [count, setCount] = useState(0);
+  return <button onClick={() => setCount(count + 1)}>{count}</button>;
+}
+```
+
+**Rule:** Only use 'use client' when you need:
+- Interactivity (useState, useEffect)
+- Browser APIs (localStorage, window)
+- Event handlers (onClick, onSubmit)
+
+## Image Optimization
+
+### 1. Next.js Image Component
+```typescript
+import Image from 'next/image';
+
+// Optimized image with automatic sizing
+<Image
+  src="/hero.jpg"
+  alt="Hero image"
+  width={1920}
+  height={1080}
+  priority // For LCP images
+  placeholder="blur"
+  blurDataURL="data:image/jpeg;base64,/9j/..." // Generated at build
+/>
+
+// Responsive image
+<Image
+  src="/hero.jpg"
+  alt="Hero image"
+  fill
+  sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw"
+  className="object-cover"
+  priority
+/>
+```
+
+### 2. Image Format Priority
+1. **AVIF** (best compression, 50% smaller than JPEG)
+2. **WebP** (wide support, 30% smaller than JPEG)
+3. **JPEG/PNG** (fallback)
+
+### 3. Cloudflare Image Optimization
+```typescript
+// next.config.ts
+images: {
+  loader: 'custom',
+  loaderFile: './lib/cloudflare-image-loader.ts',
+}
+
+// lib/cloudflare-image-loader.ts
+export default function cloudflareLoader({ src, width, quality }) {
+  const params = [`width=${width}`, `quality=${quality || 75}`, 'format=auto'];
+  return `https://mylder.io/cdn-cgi/image/${params.join(',')}/${src}`;
+}
+```
+
+### 4. Lazy Loading Images
+```typescript
+// Non-critical images (below fold)
+<Image
+  src="/feature.jpg"
+  alt="Feature"
+  width={800}
+  height={600}
+  loading="lazy" // Default, explicit here
+/>
+
+// Critical images (above fold, LCP)
+<Image
+  src="/hero.jpg"
+  alt="Hero"
+  width={1920}
+  height={1080}
+  priority // Preload immediately
+/>
+```
+
+### 5. Responsive Images Checklist
+- [ ] Use Next.js Image component (automatic optimization)
+- [ ] Set explicit width/height (prevent CLS)
+- [ ] Use `priority` for LCP images
+- [ ] Use `loading="lazy"` for below-fold images
+- [ ] Provide blur placeholder for better UX
+- [ ] Compress images before upload (80-85% quality)
+- [ ] Use modern formats (AVIF, WebP)
+
+## Font Optimization
+
+### 1. Next.js Font Optimization (Built-In)
+```typescript
+// app/layout.tsx
+import { Inter, Roboto_Mono } from 'next/font/google';
+
+const inter = Inter({
+  subsets: ['latin'],
+  display: 'swap', // Prevent invisible text flash
+  variable: '--font-inter',
+  preload: true,
+});
+
+const robotoMono = Roboto_Mono({
+  subsets: ['latin'],
+  display: 'swap',
+  variable: '--font-roboto-mono',
+  weight: ['400', '700'], // Only load needed weights
+});
+
+export default function RootLayout({ children }) {
+  return (
+    <html className={`${inter.variable} ${robotoMono.variable}`}>
+      <body className="font-sans">{children}</body>
+    </html>
+  );
+}
+```
+
+**Benefits:**
+- Self-hosted fonts (no external requests)
+- Automatic subset optimization
+- Zero layout shift (font-display: swap)
+
+### 2. Custom Fonts
+```typescript
+import localFont from 'next/font/local';
+
+const myFont = localFont({
+  src: './fonts/MyFont.woff2',
+  display: 'swap',
+  variable: '--font-my-font',
+});
+```
+
+### 3. Font Loading Best Practices
+- [ ] Use only 2-3 font families max
+- [ ] Load only needed weights (400, 700)
+- [ ] Use `font-display: swap`
+- [ ] Preload critical fonts
+- [ ] Self-host fonts (no Google Fonts CDN)
+
+## CSS Optimization
+
+### 1. Tailwind CSS Production Config
+```typescript
+// tailwind.config.ts
+import type { Config } from 'tailwindcss';
+
+const config: Config = {
+  content: [
+    './app/**/*.{ts,tsx}',
+    './components/**/*.{ts,tsx}',
+  ],
+  theme: {
+    extend: {},
+  },
+  // Remove unused styles in production
+  future: {
+    hoverOnlyWhenSupported: true, // Better mobile UX
+  },
+};
+
+export default config;
+```
+
+### 2. Critical CSS
+Next.js automatically inlines critical CSS for first paint.
+
+### 3. CSS Module Best Practices
+```typescript
+// Use CSS Modules for component-specific styles
+import styles from './Button.module.css';
+
+export function Button() {
+  return <button className={styles.button}>Click me</button>;
+}
+```
+
+## JavaScript Optimization
+
+### 1. Tree Shaking
+```typescript
+// Good: Import only what you need
+import { format } from 'date-fns';
+
+// Bad: Import entire library
+import * as dateFns from 'date-fns';
+```
+
+### 2. Remove Unused Dependencies
+```bash
+# Analyze bundle
+npx depcheck
+
+# Remove unused
+npm uninstall unused-package
+```
+
+### 3. Use Smaller Alternatives
+
+| Heavy Package | Lightweight Alternative | Savings |
+|---------------|------------------------|---------|
+| Moment.js (232KB) | date-fns (13KB) | 95% |
+| Lodash (70KB) | Lodash-es (24KB) | 66% |
+| Axios (30KB) | Fetch API (native) | 100% |
+| React Icons (full) | Lucide React (tree-shakeable) | 80% |
+
+### 4. Debounce/Throttle Heavy Operations
+```typescript
+// components/Search.tsx
+'use client';
+
+import { useState, useCallback } from 'react';
+import { debounce } from 'lodash-es/debounce';
+
+export function Search() {
+  const [query, setQuery] = useState('');
+
+  const handleSearch = useCallback(
+    debounce(async (value: string) => {
+      const results = await fetch(`/api/search?q=${value}`);
+      // Handle results
+    }, 300),
+    []
+  );
+
+  return <input onChange={(e) => handleSearch(e.target.value)} />;
+}
+```
+
+## Caching Strategy
+
+### 1. Static Generation (Fastest)
+```typescript
+// app/blog/page.tsx
+export const revalidate = false; // Static at build time
+
+export default async function Blog() {
+  const posts = await fetchPosts();
+  return <PostList posts={posts} />;
+}
+```
+
+### 2. Incremental Static Regeneration (ISR)
+```typescript
+// app/blog/[slug]/page.tsx
+export const revalidate = 3600; // Revalidate every hour
+
+export async function generateStaticParams() {
+  const posts = await fetchPosts();
+  return posts.map((post) => ({ slug: post.slug }));
+}
+
+export default async function Post({ params }) {
+  const post = await fetchPost(params.slug);
+  return <Article post={post} />;
+}
+```
+
+### 3. Server-Side Rendering (SSR)
+```typescript
+// app/dashboard/page.tsx
+export const dynamic = 'force-dynamic'; // Always server-render
+
+export default async function Dashboard() {
+  const data = await fetchUserData(); // Per-request
+  return <DashboardContent data={data} />;
+}
+```
+
+### 4. Client-Side Caching
+```typescript
+// Use SWR or React Query for client-side data fetching
+'use client';
+
+import useSWR from 'swr';
+
+export function Profile() {
+  const { data, error } = useSWR('/api/user', fetcher, {
+    revalidateOnFocus: false,
+    revalidateOnReconnect: false,
+    refreshInterval: 60000, // 1 minute
+  });
+
+  if (error) return <div>Error</div>;
+  if (!data) return <div>Loading...</div>;
+  return <div>{data.name}</div>;
+}
+```
+
+### 5. HTTP Cache Headers
+```typescript
+// app/api/data/route.ts
+export async function GET() {
+  const data = await fetchData();
+
+  return new Response(JSON.stringify(data), {
+    headers: {
+      'Content-Type': 'application/json',
+      'Cache-Control': 'public, max-age=3600, stale-while-revalidate=86400',
+    },
+  });
+}
+```
+
+## Cache Invalidation Strategy
+
+### 1. On-Demand Revalidation
+```typescript
+// app/api/revalidate/route.ts
+import { revalidatePath, revalidateTag } from 'next/cache';
+
+export async function POST(request: Request) {
+  const { path, tag } = await request.json();
+
+  if (path) {
+    revalidatePath(path);
+  }
+
+  if (tag) {
+    revalidateTag(tag);
+  }
+
+  return Response.json({ revalidated: true });
+}
+```
+
+### 2. Webhook Triggers (n8n)
+```typescript
+// n8n workflow: CMS Update → POST /api/revalidate
+{
+  "path": "/blog",
+  "tag": "posts"
+}
+```
+
+### 3. Cloudflare Cache Purge
+```bash
+# On deploy (CI/CD)
+curl -X POST "https://api.cloudflare.com/client/v4/zones/{zone_id}/purge_cache" \
+  -H "Authorization: Bearer {api_token}" \
+  -H "Content-Type: application/json" \
+  --data '{"purge_everything":true}'
+```
+
+### 4. Selective Purge
+```bash
+# Purge specific URLs
+--data '{"files":["https://mylder.io/blog","https://mylder.io/about"]}'
+
+# Purge by tag
+--data '{"tags":["blog-posts"]}'
+```
+
+## Performance Testing Workflow
+
+### 1. Pre-Deploy Checks
+```bash
+# Run before every deployment
+npm run build       # Must succeed
+npm run lint        # No errors
+npm run typecheck   # No type errors
+
+# Optional but recommended
+ANALYZE=true npm run build  # Check bundle size
+npx lighthouse https://staging.mylder.io --view
+```
+
+### 2. Post-Deploy Verification
+```bash
+# Production smoke tests
+curl -I https://mylder.io  # Check TTFB
+curl -I https://mylder.io/_next/static/[hash]/[file].js  # Check caching
+
+# Full performance audit
+npx lighthouse https://mylder.io --view
+
+# Real user monitoring
+# Check Cloudflare Analytics or Vercel Analytics dashboard
+```
+
+### 3. Continuous Monitoring
+```bash

+
+## Common Performance Issues & Fixes
+
+### Issue: High LCP (>4s)
+**Causes:**
+- Large hero image not optimized
+- Server response time (TTFB) too high
+- Render-blocking resources
+
+**Fixes:**
+- Use Next.js Image with `priority` for LCP image
+- Enable Cloudflare CDN for faster TTFB
+- Inline critical CSS
+- Preload fonts
+
+### Issue: High CLS (>0.25)
+**Causes:**
+- Images without width/height
+- Web fonts loading late
+- Dynamic content injections
+
+**Fixes:**
+- Set explicit dimensions on images
+- Use `font-display: swap`
+- Reserve space for dynamic content
+- Avoid inserting content above existing content
+
+### Issue: High FID/INP (>300ms)
+**Causes:**
+- Heavy JavaScript execution
+- Long tasks blocking main thread
+- Unoptimized event handlers
+
+**Fixes:**
+- Code split large bundles
+- Debounce/throttle event handlers
+- Use Web Workers for heavy computation
+- Optimize third-party scripts
+
+### Issue: Slow TTFB (>1s)
+**Causes:**
+- Slow server response
+- No CDN
+- Database queries during render
+
+**Fixes:**
+- Enable Cloudflare CDN
+- Use ISR instead of SSR
+- Move database queries to edge (D1)
+- Implement caching layers
+

+export function PerformanceMonitor() {
+  const pathname = usePathname();
+
+  useEffect(() => {
+    // Measure Web Vitals
+    import('web-vitals').then(({ getCLS, getFID, getFCP, getLCP, getTTFB }) => {
+      getCLS(console.log);
+      getFID(console.log);
+      getFCP(console.log);
+      getLCP(console.log);
+      getTTFB(console.log);
+    });
+  }, [pathname]);
+
+  return null;
+}
