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.

+``` + +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 +
