What problem does it solve? Building web APIs with Hono requires knowing its specific routing patterns, middleware system, validation approach, and runtime adapters. This Skill provides inline API reference knowledge so you can write correct Hono code without constantly consulting external documentation. ## Core Features & Use Cases - Routing and Middleware Reference: Covers path parameters, wildcards, route grouping with app.route() and basePath(), built-in middleware like CORS, JWT, and basic auth, plus custom middleware with createMiddleware. - Validation, JSX, and Streaming: Shows Zod and Valibot validator integration, JSX server-side rendering with hono/jsx, and streaming responses including Server-Sent Events. - Testing and Type-Safe Clients: Explains endpoint testing via npx hono request and app.request() without starting a server, plus building type-safe RPC clients with hc() and chained route exports. - Use Case: You are building a REST API on Cloudflare Workers. Use this Skill to scaffold routes with Zod validation, add JWT middleware, test endpoints with npx hono request, and export the app type for a type-safe frontend client. ## Quick Start Ask the AI to create a Hono API with a validated POST endpoint and show how to test it using npx hono request.
