- -## Router design - -chi's router is based on a kind of [Patricia Radix trie](https://en.wikipedia.org/wiki/Radix_tree). -The router is fully compatible with `net/http`. - -Built on top of the tree is the `Router` interface: - -```go -// Router consisting of the core routing methods used by chi's Mux, -// using only the standard net/http. -type Router interface { - http.Handler - Routes - - // Use appends one or more middlewares onto the Router stack. - Use(middlewares ...func(http.Handler) http.Handler) - - // With adds inline middlewares for an endpoint handler. - With(middlewares ...func(http.Handler) http.Handler) Router - - // Group adds a new inline-Router along the current routing - // path, with a fresh middleware stack for the inline-Router. - Group(fn func(r Router)) Router - - // Route mounts a sub-Router along a `pattern`` string. - Route(pattern string, fn func(r Router)) Router - - // Mount attaches another http.Handler along ./pattern/* - Mount(pattern string, h http.Handler) - - // Handle and HandleFunc adds routes for `pattern` that matches - // all HTTP methods. - Handle(pattern string, h http.Handler) - HandleFunc(pattern string, h http.HandlerFunc) - - // Method and MethodFunc adds routes for `pattern` that matches - // the `method` HTTP method. - Method(method, pattern string, h http.Handler) - MethodFunc(method, pattern string, h http.HandlerFunc) - - // HTTP-method routing along `pattern` - Connect(pattern string, h http.HandlerFunc) - Delete(pattern string, h http.HandlerFunc) - Get(pattern string, h http.HandlerFunc) - Head(pattern string, h http.HandlerFunc) - Options(pattern string, h http.HandlerFunc) - Patch(pattern string, h http.HandlerFunc) - Post(pattern string, h http.HandlerFunc) - Put(pattern string, h http.HandlerFunc) - Trace(pattern string, h http.HandlerFunc) - - // NotFound defines a handler to respond whenever a route could - // not be found. - NotFound(h http.HandlerFunc) - - // MethodNotAllowed defines a handler to respond whenever a method is - // not allowed. - MethodNotAllowed(h http.HandlerFunc) -} - -// Routes interface adds two methods for router traversal, which is also -// used by the github.com/go-chi/docgen package to generate documentation for Routers. -type Routes interface { - // Routes returns the routing tree in an easily traversable structure. - Routes() []Route - - // Middlewares returns the list of middlewares in use by the router. - Middlewares() Middlewares - - // Match searches the routing tree for a handler that matches - // the method/path - similar to routing a http request, but without - // executing the handler thereafter. - Match(rctx *Context, method, path string) bool -} -``` - -Each routing method accepts a URL `pattern` and chain of `handlers`. The URL pattern -supports named params (ie. `/users/{userID}`) and wildcards (ie. `/admin/*`). URL parameters -can be fetched at runtime by calling `chi.URLParam(r, "userID")` for named parameters -and `chi.URLParam(r, "*")` for a wildcard parameter. - - -### Middleware handlers - -chi's middlewares are just stdlib net/http middleware handlers. There is nothing special -about them, which means the router and all the tooling is designed to be compatible and -friendly with any middleware in the community. This offers much better extensibility and reuse -of packages and is at the heart of chi's purpose. - -Here is an example of a standard net/http middleware handler using the new request context -available in Go. This middleware sets a hypothetical user identifier on the request -context and calls the next handler in the chain. - -```go -// HTTP middleware setting a value on the request context -func MyMiddleware(next http.Handler) http.Handler { - return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { - ctx := context.WithValue(r.Context(), "user", "123") - next.ServeHTTP(w, r.WithContext(ctx)) - }) -} -``` - - -### Request handlers - -chi uses standard net/http request handlers. This little snippet is an example of a http.Handler -func that reads a user identifier from the request context - hypothetically, identifying -the user sending an authenticated request, validated+set by a previous middleware handler. - -```go -// HTTP handler accessing data from the request context. -func MyRequestHandler(w http.ResponseWriter, r *http.Request) { - user := r.Context().Value("user").(string) - w.Write([]byte(fmt.Sprintf("hi %s", user))) -} -``` - - -### URL parameters - -chi's router parses and stores URL parameters right onto the request context. Here is -an example of how to access URL params in your net/http handlers. And of course, middlewares -are able to access the same information. - -```go -// HTTP handler accessing the url routing parameters. -func MyRequestHandler(w http.ResponseWriter, r *http.Request) { - userID := chi.URLParam(r, "userID") // from a route like /users/{userID} - - ctx := r.Context() - key := ctx.Value("key").(string) - - w.Write([]byte(fmt.Sprintf("hi %v, %v", userID, key))) -} -``` - - -## Middlewares - -chi comes equipped with an optional `middleware` package, providing a suite of standard -`net/http` middlewares. Please note, any middleware in the ecosystem that is also compatible -with `net/http` can be used with chi's mux. - -### Core middlewares - ------------------------------------------------------------------------------------------------------------ -| chi/middleware Handler | description | -|:----------------------|:--------------------------------------------------------------------------------- -| AllowContentType | Explicit whitelist of accepted request Content-Types | -| BasicAuth | Basic HTTP authentication | -| Compress | Gzip compression for clients that accept compressed responses | -| GetHead | Automatically route undefined HEAD requests to GET handlers | -| Heartbeat | Monitoring endpoint to check the servers pulse | -| Logger | Logs the start and end of each request with the elapsed processing time | -| NoCache | Sets response headers to prevent clients from caching | -| Profiler | Easily attach net/http/pprof to your routers | -| RealIP | Sets a http.Request's RemoteAddr to either X-Forwarded-For or X-Real-IP | -| Recoverer | Gracefully absorb panics and prints the stack trace | -| RequestID | Injects a request ID into the context of each request | -| RedirectSlashes | Redirect slashes on routing paths | -| SetHeader | Short-hand middleware to set a response header key/value | -| StripSlashes | Strip slashes on routing paths | -| Throttle | Puts a ceiling on the number of concurrent requests | -| Timeout | Signals to the request context when the timeout deadline is reached | -| URLFormat | Parse extension from url and put it on request context | -| WithValue | Short-hand middleware to set a key/value on the request context | ------------------------------------------------------------------------------------------------------------ - -### Extra middlewares & packages - -Please see https://github.com/go-chi for additional packages. - --------------------------------------------------------------------------------------------------------------------- -| package | description | -|:---------------------------------------------------|:------------------------------------------------------------- -| [cors](https://github.com/go-chi/cors) | Cross-origin resource sharing (CORS) | -| [docgen](https://github.com/go-chi/docgen) | Print chi.Router routes at runtime | -| [jwtauth](https://github.com/go-chi/jwtauth) | JWT authentication | -| [hostrouter](https://github.com/go-chi/hostrouter) | Domain/host based request routing | -| [httplog](https://github.com/go-chi/httplog) | Small but powerful structured HTTP request logging | -| [httprate](https://github.com/go-chi/httprate) | HTTP request rate limiter | -| [httptracer](https://github.com/go-chi/httptracer) | HTTP request performance tracing library | -| [httpvcr](https://github.com/go-chi/httpvcr) | Write deterministic tests for external sources | -| [stampede](https://github.com/go-chi/stampede) | HTTP request coalescer | --------------------------------------------------------------------------------------------------------------------- - -please [submit a PR](./CONTRIBUTING.md) if you'd like to include a link to a chi-compatible middleware - - -## context? - -`context` is a tiny pkg that provides simple interface to signal context across call stacks -and goroutines.
