Cloudflare Developer Platform Skill

Cloudflare Developer Platform is a comprehensive edge computing ecosystem for building full-stack applications on Cloudflare's global network. It includes serverless functions, databases, storage, AI/ML capabilities, and static site hosting.

When to Use This Skill

Use this skill when:

•Building serverless applications on the edge
•Implementing edge databases (D1 SQLite)
•Working with object storage (R2) or key-value stores (KV)
•Creating real-time applications with WebSockets (Durable Objects)
•Integrating AI/ML capabilities (Workers AI, AI Gateway, Agents)
•Deploying static sites with serverless functions (Pages)
•Building full-stack applications with frameworks (Next.js, Remix, Astro, etc.)
•Implementing message queues and background jobs (Queues)
•Optimizing for global performance and low latency

Core Concepts

Edge Computing Platform

Cloudflare's Edge Network: Code runs on servers globally distributed across 300+ cities, executing requests from the nearest location for ultra-low latency.

Key Components:

•Workers: Serverless functions on the edge
•D1: SQLite database with global read replication
•KV: Distributed key-value store with eventual consistency
•R2: Object storage with zero egress fees
•Durable Objects: Stateful compute with WebSocket support
•Queues: Message queue system for async processing
•Pages: Static site hosting with serverless functions
•Workers AI: Run AI models on the edge
•AI Gateway: Unified interface for AI providers

Execution Model

V8 Isolates: Lightweight execution environments (faster than containers) with:

•Millisecond cold starts
•Zero infrastructure management
•Automatic scaling
•Pay-per-request pricing

Handler Types:

•fetch: HTTP requests
•scheduled: Cron jobs
•queue: Message processing
•tail: Log aggregation
•email: Email handling
•alarm: Durable Object timers

Polyglot Storage Pattern

typescript

export default {
  async fetch(request: Request, env: Env) {
    const url = new URL(request.url);

    // KV: Fast cache
    const cached = await env.KV.get(url.pathname);
    if (cached) return new Response(cached);

    // D1: Structured data
    const user = await env.DB.prepare('SELECT * FROM users WHERE id = ?').bind(userId).first();

    // R2: Media files
    const avatar = await env.R2_BUCKET.get(`avatars/${user.id}.jpg`);

    // Durable Objects: Real-time coordination
    const chat = env.CHAT_ROOM.get(env.CHAT_ROOM.idFromName(roomId));

    // Queue: Async processing
    await env.EMAIL_QUEUE.send({ to: user.email, template: 'welcome' });

    return new Response(JSON.stringify({ user, avatar }));
  },
};

Authentication Pattern

typescript

import { verifyJWT, createJWT } from './jwt';

export default {
  async fetch(request: Request, env: Env) {
    const url = new URL(request.url);

    // Login
    if (url.pathname === '/api/login') {
      const { email, password } = await request.json();

      const user = await env.DB.prepare('SELECT * FROM users WHERE email = ?').bind(email).first();

      if (!user || !(await verifyPassword(password, user.password_hash))) {
        return new Response('Invalid credentials', { status: 401 });
      }

      const token = await createJWT({ userId: user.id }, env.JWT_SECRET);

      return new Response(JSON.stringify({ token }), {
        headers: { 'Content-Type': 'application/json' },
      });
    }

    // Protected route
    const authHeader = request.headers.get('Authorization');
    if (!authHeader) {
      return new Response('Unauthorized', { status: 401 });
    }

    const token = authHeader.replace('Bearer ', '');
    const payload = await verifyJWT(token, env.JWT_SECRET);

    // Store session in KV
    await env.KV.put(`session:${payload.userId}`, JSON.stringify(payload), {
      expirationTtl: 86400, // 24 hours
    });

    return new Response('Authenticated');
  },
};

Cache Strategy

typescript

export default {
  async fetch(request: Request, env: Env) {
    const cache = caches.default;
    const cacheKey = new Request(request.url);

    // Check cache
    let response = await cache.match(cacheKey);
    if (response) return response;

    // Check KV (distributed cache)
    const kvCached = await env.KV.get(request.url);
    if (kvCached) {
      response = new Response(kvCached);
      await cache.put(cacheKey, response.clone());
      return response;
    }

    // Fetch from origin (D1, R2, etc.)
    const data = await fetchFromOrigin(request, env);
    response = new Response(data);

    // Store in both caches
    await cache.put(cacheKey, response.clone());
    await env.KV.put(request.url, data, { expirationTtl: 3600 });

    return response;
  },
};

Best Practices

Performance

•Minimize Cold Starts: Keep Workers lightweight (<1MB bundled)
•Use Bindings Over Fetch: Direct bindings are faster than HTTP calls
•Edge Caching: Leverage KV and Cache API for frequently accessed data
•Batch Operations: Use D1 batch for multiple queries
•Stream Large Responses: Use Response.body streams for large files

Security

•Secrets Management: Use wrangler secret for API keys
•Environment Isolation: Separate production/staging/development
•Input Validation: Sanitize user input
•Rate Limiting: Use KV or Durable Objects for rate limiting
•CORS: Configure proper CORS headers

Cost Optimization

•R2 for Large Files: Zero egress fees vs S3
•KV for Caching: Reduce D1/R2 requests
•Request Deduplication: Cache identical requests
•Efficient Queries: Index D1 tables properly
•Monitor Usage: Use Cloudflare Analytics

Development Workflow

•Local Development: Use wrangler dev for testing
•Type Safety: Use TypeScript with @cloudflare/workers-types
•Testing: Use Vitest with unstable_dev()
•CI/CD: GitHub Actions with cloudflare/wrangler-action
•Gradual Deployments: Use percentage-based rollouts

Common Patterns

API Gateway

typescript

import { Hono } from 'hono';

const app = new Hono();

app.get('/api/users/:id', async (c) => {
  const user = await c.env.DB.prepare('SELECT * FROM users WHERE id = ?')
    .bind(c.req.param('id'))
    .first();

  return c.json(user);
});

app.post('/api/users', async (c) => {
  const { name, email } = await c.req.json();

  await c.env.DB.prepare('INSERT INTO users (name, email) VALUES (?, ?)').bind(name, email).run();

  return c.json({ success: true }, 201);
});

export default app;

Image Transformation

typescript

export default {
  async fetch(request: Request, env: Env) {
    const url = new URL(request.url);
    const imageKey = url.pathname.replace('/images/', '');

    // Get from R2
    const object = await env.R2_BUCKET.get(imageKey);
    if (!object) {
      return new Response('Not found', { status: 404 });
    }

    // Transform with Cloudflare Images
    return new Response(object.body, {
      headers: {
        'Content-Type': object.httpMetadata?.contentType || 'image/jpeg',
        'Cache-Control': 'public, max-age=86400',
        'cf-image-resize': JSON.stringify({
          width: 800,
          height: 600,
          fit: 'cover',
        }),
      },
    });
  },
};

Rate Limiting (KV)

typescript

async function rateLimit(ip: string, env: Env): Promise<boolean> {
  const key = `ratelimit:${ip}`;
  const limit = 100; // requests per minute
  const window = 60; // seconds

  const current = await env.KV.get(key);
  const count = current ? parseInt(current) : 0;

  if (count >= limit) {
    return false; // Rate limit exceeded
  }

  await env.KV.put(key, (count + 1).toString(), {
    expirationTtl: window,
  });

  return true;
}

export default {
  async fetch(request: Request, env: Env) {
    const ip = request.headers.get('CF-Connecting-IP') || 'unknown';

    if (!(await rateLimit(ip, env))) {
      return new Response('Rate limit exceeded', { status: 429 });
    }

    return new Response('OK');
  },
};

Scheduled Jobs

toml

# wrangler.toml
[triggers]
crons = ["0 0 * * *"] # Daily at midnight

typescript

export default {
  async scheduled(event: ScheduledEvent, env: Env) {
    // Cleanup old sessions
    const sessions = await env.KV.list({ prefix: 'session:' });
    for (const key of sessions.keys) {
      const session = await env.KV.get(key.name, 'json');
      if (session.expiresAt < Date.now()) {
        await env.KV.delete(key.name);
      }
    }
  },
};

Troubleshooting

Common Issues

"Module not found" errors

•Ensure dependencies are in package.json
•Run npm install before deploying
•Check compatibility_date in wrangler.toml

Database connection errors (D1)

•Verify database_id in wrangler.toml
•Check database exists: wrangler d1 list
•Run migrations: wrangler d1 execute DB --file=schema.sql

KV not found errors

•Create namespace: wrangler kv:namespace create MY_KV
•Add binding to wrangler.toml
•Deploy after configuration changes

Cold start timeout

•Reduce bundle size (<1MB ideal)
•Remove unnecessary dependencies
•Use dynamic imports for large libraries

CORS errors

•Add CORS headers to responses:

typescript

return new Response(data, {
  headers: {
    'Access-Control-Allow-Origin': '*',
    'Access-Control-Allow-Methods': 'GET, POST, OPTIONS',
    'Access-Control-Allow-Headers': 'Content-Type',
  },
});

Deployment fails

•Check wrangler version: wrangler --version
•Verify authentication: wrangler whoami
•Review build errors in console output

Debugging

bash

# Real-time logs
wrangler tail

# Local debugging with breakpoints
wrangler dev --local

# Remote debugging
wrangler dev --remote

# Check deployment status
wrangler deployments list

Decision Matrix

Need	Choose
Sub-millisecond reads	KV
SQL queries	D1
Large files (>25MB)	R2
Real-time WebSockets	Durable Objects
