Cloudflare Workers Quick Start Guide

Cloudflare Workers Quick Start Guide

Just deployed my first Cloudflare Worker and it was incredibly fast!

What I Learned

Deployment Speed

• From project creation to production: ~5 minutes
• Zero cold starts (< 1ms)
• Global deployment across 300+ locations

Key Configuration

{
  "name": "my-worker",
  "main": "src/index.ts",
  "compatibility_date": "2025-01-01"
}

Important: Always use the current date for compatibility_date to get the latest features!

TypeScript Integration

npx wrangler types  # Generates .wrangler/types/runtime.d.ts

Then import in your code:

import type { Env } from './.wrangler/types/runtime';

Useful Commands

• npx wrangler dev - Local development
• npx wrangler dev --remote - Local with real resources
• npx wrangler deploy - Deploy to production
• npx wrangler tail - Real-time logs

Next Steps

• Add KV storage for caching
• Integrate D1 database
• Set up cron jobs for scheduled tasks
