Building an API with Cloudflare Workers and D1#
This tutorial walks through building a production API on Cloudflare Workers with a D1 database, KV caching, rate limiting, full-text search, and request logging. The patterns come from a real production deployment – not a toy example.
By the end you will have: a TypeScript Worker handling multiple API routes, a D1 database with FTS5 full-text search, KV-based caching and rate limiting, CORS support, request logging with IP hashing for privacy, and a deployment to Cloudflare’s global network.
