Source inspection; upstream code and tests were not executed.

The user-facing product is a framework API and exported modules rather than a fixed application route set. Routing, responses, middleware and validation form the server surface. Typed clients, JSX, streaming, WebSockets and static generation extend it into full web application development. The export-map inventory is broader than the implementation paths examined in detail.
- Applications register get/post/put/delete/options/patch/query/all handlers, arbitrary method/path combinations through on(), and path-scoped middleware through use(). — [src/hono-base.ts#L104-113](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/hono-base.ts#L104-L113) [src/hono-base.ts#L127-170](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/hono-base.ts#L127-L170)
- route() groups Hono applications, basePath() prefixes registration, and mount() integrates another Request handler with configurable request replacement and arguments. — [src/hono-base.ts#L211-255](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/hono-base.ts#L211-L255) [src/hono-base.ts#L331-384](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/hono-base.ts#L331-L384)
- Context exposes text, JSON, HTML, redirect and custom-body response construction; onError() and notFound() customize application failures. — [src/context.ts#L681-750](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/context.ts#L681-L750) [src/context.ts#L767-779](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/context.ts#L767-L779) [src/hono-base.ts#L274-297](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/hono-base.ts#L274-L297)

- hc() supplies proxy-generated HTTP calls, $url/$path helpers and $ws connections, with form, JSON, query, parameter, header and cookie inputs. — [src/client/client.ts#L58-146](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/client/client.ts#L58-L146) [src/client/client.ts#L179-246](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/client/client.ts#L179-L246)
- The JSR export map exposes authentication, IP restriction, body limits, cache, compression, CORS, CSRF, ETag and trailing-slash middleware. — [jsr.json#L16-29](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/jsr.json#L16-L29) [jsr.json#L43-44](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/jsr.json#L43-L44)
- Additional exported middleware covers timeouts, timing, logging, method handling, request IDs, language selection, secure headers, JSON formatting and middleware combinations. — [jsr.json#L45-55](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/jsr.json#L45-L55)
- Hono JSX exports components, context, hooks, Suspense and ErrorBoundary; the DOM package additionally exports render, portals, flushSync and form-state hooks. — [src/jsx/index.ts#L36-73](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/jsx/index.ts#L36-L73) [src/jsx/dom/index.ts#L33-39](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/jsx/dom/index.ts#L33-L39) [src/jsx/dom/index.ts#L85-125](https://github.com/honojs/hono/blob/f23b146afcec63606144cde50b5fbd360dd60238/src/jsx/dom/index.ts#L85-L125)
