What problem does it solve? Building Hono web applications requires knowing its specific APIs for routing, middleware, validation, JSX rendering, and streaming, and developers often need to test endpoints without starting a server. ## Core Features & Use Cases - Routing & Middleware Reference: Provides inline API knowledge for Hono routing patterns, route grouping, built-in middleware (CORS, JWT, auth, caching), and custom middleware creation. - Validation & Type-Safe RPC: Covers Zod and Valibot validators plus the Hono RPC client pattern for end-to-end type safety between server and client. - Endpoint Testing Without a Server: Use npx hono request or app.request() to test endpoints directly, with workers-fetch as a fallback for Cloudflare Workers bindings. - Use Case: When building a REST API with Hono on Cloudflare Workers, use this Skill to scaffold routes with Zod validation, chain them for RPC type inference, and test each endpoint via the CLI before deployment. ## Quick Start Ask the AI to create a Hono API route with Zod validation and test it using npx hono request.
