Edge Computing

Example Prompts

• "Build a Cloudflare Worker for A/B testing at the edge"
• "Create an edge function for geo-based personalization"
• "Implement rate limiting at the edge using KV"

Example Output

export default {
  async fetch(request: Request, env: Env): Promise<Response> {
    const ip = request.headers.get('CF-Connecting-IP')!;
    const key = `rate:${ip}:${Math.floor(Date.now() / 60000)}`;
    const count = parseInt(await env.RATE_KV.get(key) || '0');
    if (count >= 100) return new Response('Rate limited', { status: 429 });
    await env.RATE_KV.put(key, String(count + 1), { expirationTtl: 120 });
    return fetch(request);
  }
