The public surface is primarily Go APIs for defining and operating HTTP applications. Routing includes groups, mounted applications, domain patterns, constraints, and named-route redirects. Request binding and response serialization coexist with files, templates, streaming, sessions, and an outbound client. The middleware catalog adds authentication, HTTP policy, operational diagnostics, and response-processing features.
- Add accepts multiple methods, All uses configured RequestMethods, Group adds prefix middleware, Domain scopes routes by hostname patterns, and RouteChain groups registrations for one path. — [app.go#L1186-L1251](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/app.go#L1186-L1251)
- Handlers can use Fiber Ctx, separate Req/Res signatures with next callbacks, net/http handlers, or fasthttp handlers through toFiberHandler's adapters. — [adapter.go#L12-L29](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/adapter.go#L12-L29) [adapter.go#L52-L83](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/adapter.go#L52-L83)
- Bind.Body dispatches JSON, XML, MessagePack, CBOR, URL-encoded forms, and multipart forms; Bind.All combines URI, body, query, headers, and cookies with configurable precedence. — [bind.go#L393-L430](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/bind.go#L393-L430) [bind.go#L505-L567](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/bind.go#L505-L567)
- Responses support JSON, MessagePack, and CBOR encoders; Views supplies template rendering, and static.New exposes browsing, byte ranges, compression, cache duration, and index-name options. — [res.go#L711-L764](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/res.go#L711-L764) [ctx.go#L191-L194](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/ctx.go#L191-L194) [middleware/static/static.go#L282-L298](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/middleware/static/static.go#L282-L298)
- Redirect.To sets Location and status and processes flash messages; Redirect.Route resolves a named route and appends escaped query values. SSE supplies event streams with Last-Event-ID, retry advice, heartbeats, and close callbacks. — [redirect.go#L334-L390](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/redirect.go#L334-L390) [middleware/sse/sse.go#L24-L78](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/middleware/sse/sse.go#L24-L78)
- Session middleware exposes stored key/value state with automatic saving; Basic Auth delegates decoded credentials to Authorizer, and keyauth delegates extracted keys to Validator with authentication challenges. — [middleware/session/middleware.go#L92-L123](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/middleware/session/middleware.go#L92-L123) [middleware/basicauth/basicauth.go#L93-L118](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/middleware/basicauth/basicauth.go#L93-L118) [middleware/keyauth/keyauth.go#L85-L120](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/middleware/keyauth/keyauth.go#L85-L120)
- The outbound client provides verb helpers, pooled requests, JSON/XML/form/file/raw/CBOR bodies, selectable fasthttp transports, hook stages, timeouts, redirects, and exponential-backoff retries. — [client/client.go#L737-L743](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/client/client.go#L737-L743) [client/client.go#L952-L1007](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/client/client.go#L952-L1007) [client/request.go#L28-L72](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/client/request.go#L28-L72) [client/core.go#L98-L111](https://github.com/gofiber/fiber/blob/0923873f4a1bd7e5582ab0d6729cf04e683db2ae/client/core.go#L98-L111)
