Today, `chi` still has zero dependencies, -and in many ways is future proofed from changes, given it's minimal nature. Between versions, chi's iterations have been very -incremental, with the architecture and api being the same today as it was originally designed in 2016. For this reason it -makes chi a pretty easy project to maintain, as well thanks to the many amazing community contributions over the years -to who all help make chi better (total of 86 contributors to date -- thanks all!). - -Chi has been an labour of love, art and engineering, with the goals to offer beautiful ergonomics, flexibility, performance -and simplicity when building HTTP services with Go. I've strived to keep the router very minimal in surface area / code size, -and always improving the code wherever possible -- and as of today the `chi` package is just 1082 lines of code (not counting -middlewares, which are all optional). As well, I don't have the exact metrics, but from my analysis and email exchanges from -companies and developers, chi is used by thousands of projects around the world -- thank you all as there is no better form of -joy for me than to have art I had started be helpful and enjoyed by others. And of course I use chi in all of my own projects too :) - -For me, the asthetics of chi's code and usage are very important. With the introduction of Go's module support -(which I'm a big fan of), chi's past versioning scheme choice to v2, v3 and v4 would mean I'd require the import path -of "github.com/go-chi/chi/v4", leading to the lengthy discussion at https://github.com/go-chi/chi/issues/462. -Haha, to some, you may be scratching your head why I've spent > 1 year stalling to adopt "/vXX" convention in the import -path -- which isn't horrible in general -- but for chi, I'm unable to accept it as I strive for perfection in it's API design, -aesthetics and simplicity. It just doesn't feel good to me given chi's simple nature -- I do not foresee a "v5" or "v6", -and upgrading between versions in the future will also be just incremental. - -I do understand versioning is a part of the API design as well, which is why the solution for a while has been to "do nothing", -as Go supports both old and new import paths with/out go.mod. However, now that Go module support has had time to iron out kinks and -is adopted everywhere, it's time for chi to get with the times. Luckily, I've discovered a path forward that will make me happy, -while also not breaking anyone's app who adopted a prior versioning from tags in v2/v3/v4. I've made an experimental release of -v1.5.0 with go.mod silently, and tested it with new and old projects, to ensure the developer experience is preserved, and it's -largely unnoticed. Fortunately, Go's toolchain will check the tags of a repo and consider the "latest" tag the one with go.mod. -However, you can still request a specific older tag such as v4.1.2, and everything will "just work". But new users can just -`go get github.com/go-chi/chi` or `go get github.com/go-chi/chi@latest` and they will get the latest version which contains -go.mod support, which is v1.5.0+. `chi` will not change very much over the years, just like it hasn't changed much from 4 years ago. -Therefore, we will stay on v1.x from here on, starting from v1.5.0. Any breaking changes will bump a "minor" release and -backwards-compatible improvements/fixes will bump a "tiny" release. - -For existing projects who want to upgrade to the latest go.mod version, run: `go get -u github.com/go-chi/chi@v1.5.0`, -which will get you on the go.mod version line (as Go's mod cache may still remember v4.x). Brand new systems can run -`go get -u github.com/go-chi/chi` or `go get -u github.com/go-chi/chi@latest` to install chi, which will install v1.5.0+ -built with go.mod support. - -My apologies to the developers who will disagree with the decisions above, but, hope you'll try it and see it's a very -minor request which is backwards compatible and won't break your existing installations. - -Cheers all, happy coding! - - ---- - - -## v4.1.2 (2020-06-02) - -- fix that handles MethodNotAllowed with path variables, thank you @caseyhadden for your contribution -- fix to replace nested wildcards correctly in RoutePattern, thank you @@unmultimedio for your contribution -- History of changes: see https://github.com/go-chi/chi/compare/v4.1.1...v4.1.2 - - -## v4.1.1 (2020-04-16) - -- fix for issue https://github.com/go-chi/chi/issues/411 which allows for overlapping regexp - route to the correct handler through a recursive tree search, thanks to @Jahaja for the PR/fix! -- new middleware.RouteHeaders as a simple router for request headers with wildcard support -- History of changes: see https://github.com/go-chi/chi/compare/v4.1.0...v4.1.1 - - -## v4.1.0 (2020-04-1) - -- middleware.LogEntry: Write method on interface now passes the response header - and an extra interface type useful for custom logger implementations. -- middleware.WrapResponseWriter: minor fix -- middleware.Recoverer: a bit prettier -- History of changes: see https://github.com/go-chi/chi/compare/v4.0.4...v4.1.0 - -## v4.0.4 (2020-03-24) - -- middleware.Recoverer: new pretty stack trace printing (https://github.com/go-chi/chi/pull/496) -- a few minor improvements and fixes -- History of changes: see https://github.com/go-chi/chi/compare/v4.0.3...v4.0.4 - - -## v4.0.3 (2020-01-09) - -- core: fix regexp routing to include default value when param is not matched -- middleware: rewrite of middleware.Compress -- middleware: suppress http.ErrAbortHandler in middleware.Recoverer -- History of changes: see https://github.com/go-chi/chi/compare/v4.0.2...v4.0.3 - - -## v4.0.2 (2019-02-26) - -- Minor fixes -- History of changes: see https://github.com/go-chi/chi/compare/v4.0.1...v4.0.2 - - -## v4.0.1 (2019-01-21) - -- Fixes issue with compress middleware: #382 #385 -- History of changes: see https://github.com/go-chi/chi/compare/v4.0.0...v4.0.1 - - -## v4.0.0 (2019-01-10) - -- chi v4 requires Go 1.10.3+ (or Go 1.9.7+) - we have deprecated support for Go 1.7 and 1.8 -- router: respond with 404 on router with no routes (#362) -- router: additional check to ensure wildcard is at the end of a url pattern (#333) -- middleware: deprecate use of http.CloseNotifier (#347) -- middleware: fix RedirectSlashes to include query params on redirect (#334) -- History of changes: see https://github.com/go-chi/chi/compare/v3.3.4...v4.0.0 - - -## v3.3.4 (2019-01-07) - -- Minor middleware improvements.

- -## Router interface - -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 where we assign a context key `"user"` -the value of `"123"`. 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) { - // create new context from `r` request context, and assign key `"user"` - // to value of `"123"` - ctx := context.WithValue(r.Context(), "user", "123") - - // call the next handler in the chain, passing the response writer and - // the updated request object with the new context value. - // - // note: context.Context values are nested, so any previously set - // values will be accessible as well, and the new `"user"` key - // will be accessible from this point forward. - 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) { - // here we read from the request context and fetch out `"user"` key set in - // the MyMiddleware example above. - user := r.Context().Value("user").(string) - - // respond to the client - 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) { - // fetch the url parameter `"userID"` from the request of a matching - // routing pattern. An example routing pattern could be: /users/{userID} - userID := chi.URLParam(r, "userID") - - // fetch `"key"` from the request context - ctx := r.Context() - key := ctx.Value("key").(string) - - // respond to the client - 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 | -| :--------------------- | :---------------------------------------------------------------------- | -| [AllowContentEncoding] | Enforces a whitelist of request Content-Encoding headers | -| [AllowContentType] | Explicit whitelist of accepted request Content-Types | -| [BasicAuth] | Basic HTTP authentication | -| [Compress] | Gzip compression for clients that accept compressed responses | -| [ContentCharset] | Ensure charset for Content-Type request headers | -| [CleanPath] | Clean double slashes from request path | -| [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 | -| [RouteHeaders] | Route handling for request headers | -| [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 | ----------------------------------------------------------------------------------------------------- -
