When should I avoid using a framework for my Worker?

Use a vanilla fetch handler when your Worker is single-purpose (like a simple redirect), requires maximum performance, or needs minimal dependencies.

How does itty-router compare to Hono in terms of size?

itty-router is extremely lightweight at ~1KB, whereas Hono is ~14KB. itty-router is ideal when bundle size is the primary concern.

Which framework is best for large Cloudflare Workers projects?

Hono is recommended for large projects due to its extensive middleware ecosystem, excellent TypeScript support, and Express-like API.

Can I use Zod for validation with these frameworks?

Yes, this skill includes specific patterns for using Zod with Hono via the @hono/zod-validator to ensure type-safe request handling.

Does this skill help with Workers AI integration?

Yes, it provides implementation patterns for integrating Workers AI within framework routes, including streaming response support.

Cloud Infrastructure

Streamlines the selection and implementation of web frameworks like Hono and itty-router for Cloudflare Workers development.

About

This skill provides expert guidance on architecting Cloudflare Workers using modern web frameworks. It offers deep technical comparisons between Hono, itty-router, and vanilla fetch handlers, helping developers choose the right tool based on bundle size, type safety, and complexity requirements. With ready-to-use boilerplate for routing, middleware, and Workers AI integration, it accelerates the transition from simple scripts to production-grade REST APIs and serverless applications.

Key Features

Type-safe routing configurations for TypeScript
Migration strategies from vanilla handlers to modern frameworks
Framework comparison between Hono, itty-router, and vanilla JS
Production-ready middleware implementation patterns
Integration guides for Workers AI, D1 Database, and KV
1 GitHub stars

Use Cases

Building complex REST APIs on the Cloudflare Edge
Optimizing Worker bundle sizes for high-performance applications
Implementing custom middleware for authentication and logging
