Web Frameworks for Workers

Purpose

This skill provides guidance on web frameworks for Cloudflare Workers, with focus on Hono and itty-router—the two most popular choices. Use this when building API endpoints, adding middleware, or choosing between vanilla fetch handlers and framework-based routing.

When to Use a Framework

Use a framework when:

• Multiple routes/endpoints (>3-4)
• Need middleware (auth, logging, CORS)
• Building a REST API
• Want type-safe routing
• Team is familiar with Express-like patterns
