chi

GoDoc Widget Travis Widget

chi is a lightweight, idiomatic and composable router for building Go 1.7+ HTTP services. It's especially good at helping you write large REST API services that are kept maintainable as your project grows and changes. chi is built on the new context package introduced in Go 1.7 to handle signaling, cancelation and request-scoped values across a handler chain.

The focus of the project has been to seek out an elegant and comfortable design for writing REST API servers, written during the development of the Pressly API service that powers our public API service, which in turn powers all of our client-side applications.

The key considerations of chi's design are: project structure, maintainability, standard http handlers (stdlib-only), developer productivity, and deconstructing a large system into many small parts. The core router github.com/pressly/chi is quite small (less than 1000 LOC), but we've also included some useful/optional subpackages: middleware, render and docgen. We hope you enjoy it too!

Install

go get -u github.com/pressly/chi

Features

  • Lightweight - cloc'd in <1000 LOC for the chi router
  • Fast - yes, see benchmarks
  • 100% compatible with net/http - use any http or middleware pkg in the ecosystem that is also compat with net/http
  • Designed for modular/composable APIs - middlewares, inline middlewares, route groups and subrouter mounting
  • Context control - built on new context package, providing value chaining, cancelations and timeouts
  • Robust - tested / used in production at Pressly.com, and many others
  • Doc generation - docgen auto-generates routing documentation from your source to JSON or Markdown
  • No external dependencies - plain ol' Go 1.7+ stdlib + net/http

Examples

  • rest - REST APIs made easy, productive and maintainable
  • logging - Easy structured logging for any backend
  • limits - Timeouts and Throttling
  • todos-resource - Struct routers/handlers, an example of another code layout style
  • versions - Demo of chi/render subpkg
  • fileserver - Easily serve static files
  • graceful - Graceful context signaling and server shutdown

As easy as:

package main

import (
	"net/http"
	"github.com/pressly/chi"
)

func main() {
	r := chi.NewRouter()
	r.Get("/", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("welcome"))
	})
	http.ListenAndServe(":3000", r)
}

REST Preview:

Here is a little preview of how routing looks like with chi. Also take a look at the generated routing docs in JSON (routes.json) and in Markdown (routes.md).

I highly recommend reading the source of the examples listed above, they will show you all the features of chi and serve as a good form of documentation.

import (
  //...
  "context"
  "github.com/pressly/chi"
  "github.com/pressly/chi/middleware"
)

func main() {
  r := chi.NewRouter()

  // A good base middleware stack
  r.Use(middleware.RequestID)
  r.Use(middleware.RealIP)
  r.Use(middleware.Logger)
  r.Use(middleware.Recoverer)

  // When a client closes their connection midway through a request, the
  // http.CloseNotifier will cancel the request context (ctx).
  r.Use(middleware.CloseNotify)

  // Set a timeout value on the request context (ctx), that will signal
  // through ctx.Done() that the request has timed out and further
  // processing should be stopped.
  r.Use(middleware.Timeout(60 * time.Second))

  r.Get("/", func(w http.ResponseWriter, r *http.Request) {
    w.Write([]byte("hi"))
  })

  // RESTy routes for "articles" resource
  r.Route("/articles", func(r chi.Router) {
    r.With(paginate).Get("/", listArticles)  // GET /articles
    r.Post("/", createArticle)               // POST /articles
    r.Get("/search", searchArticles)         // GET /articles/search

    r.Route("/:articleID", func(r chi.Router) {
      r.Use(ArticleCtx)
      r.Get("/", getArticle)                 // GET /articles/123
      r.Put("/", updateArticle)              // PUT /articles/123
      r.Delete("/", deleteArticle)           // DELETE /articles/123
    })
  })

  // Mount the admin sub-router
  r.Mount("/admin", adminRouter())

  http.ListenAndServe(":3333", r)
}

func ArticleCtx(next http.Handler) http.Handler {
  return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
    articleID := chi.URLParam(r, "articleID")
    article, err := dbGetArticle(articleID)
    if err != nil {
      http.Error(w, http.StatusText(404), 404)
      return
    }
    ctx := context.WithValue(r.Context(), "article", article)
    next.ServeHTTP(w, r.WithContext(ctx))
  })
}

func getArticle(w http.ResponseWriter, r *http.Request) {
  ctx := r.Context()
  article, ok := ctx.Value("article").(*Article)
  if !ok {
    http.Error(w, http.StatusText(422), 422)
    return
  }
  w.Write([]byte(fmt.Sprintf("title:%s", article.Title)))
}

// A completely separate router for administrator routes
func adminRouter() http.Handler {
  r := chi.NewRouter()
  r.Use(AdminOnly)
  r.Get("/", adminIndex)
  r.Get("/accounts", adminListAccounts)
  return r
}

func AdminOnly(next http.Handler) http.Handler {
  return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
    ctx := r.Context()
    perm, ok := ctx.Value("acl.permission").(YourPermissionType)
    if !ok || !perm.IsAdmin() {
      http.Error(w, http.StatusText(403), 403)
      return
    }
    next.ServeHTTP(w, r)
  })
}

Router design

chi's router is based on a kind of Patricia Radix trie. The router is fully compatible with net/http.

Built on top of the tree is the Router interface:

// 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 of 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)

	// 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)
}

// Routes interface adds two methods for router traversal, which is also
// used by the `docgen` subpackage to generation 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
}

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 1.7+. This middleware sets a hypothetical user identifier on the request context and calls the next handler in the chain.

// 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.

// 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.

// 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.


Middleware Description
RequestID Injects a request ID into the context of each request.
RealIP Sets a http.Request's RemoteAddr to either X-Forwarded-For or X-Real-IP.
Logger Logs the start and end of each request with the elapsed processing time.
Recoverer Gracefully absorb panics and prints the stack trace.
NoCache Sets response headers to prevent clients from caching.
Timeout Signals to the request context when the timeout deadline is reached.
Throttle Puts a ceiling on the number of concurrent requests.
Compress Gzip compression for clients that accept compressed responses.
Profiler Easily attach net/http/pprof to your routers.
StripSlashes Strip slashes on routing paths.
RedirectSlashes Redirect slashes on routing paths.
WithValue Short-hand middleware to set a key/value on the request context.
Heartbeat Monitoring endpoint to check the servers pulse.

NOTE: the allocs in the benchmark above are from the calls to http.Request's WithContext(context.Context) method that clones the http.Request, sets the Context() on the duplicated (alloc'd) request and returns it the new request object. This is just how setting context on a request in Go 1.7+ works.

Beyond REST

chi is just a http router that lets you decompose request handling into many smaller layers. Many companies including Pressly.com (of course) use chi to write REST services for their public APIs. But, REST is just a convention for managing state via HTTP, and there's a lot of other pieces required to write a complete client-server system or network of microservices.

Looking ahead beyond REST, I also recommend some newer works in the field coming from gRPC, NATS, go-kit and even graphql. They're all pretty cool with their own unique approaches and benefits. Specifically, I'd look at gRPC since it makes client-server communication feel like a single program on a single computer, no need to hand-write a client library and the request/response payloads are typed contracts. NATS is pretty amazing too as a super fast and lightweight pub-sub transport that can speak protobufs, with nice service discovery - an excellent combination with gRPC.

type Middlewares

type Middlewares []func(http.Handler) http.Handler

Middlewares type is a slice of standard middleware handlers with methods to compose middleware chains and http.Handler's.

func Chain

func Chain(middlewares ...func(http.Handler) http.Handler) Middlewares

Chain returns a Middlewares type from a slice of middleware handlers.

func (Middlewares) Handler

func (mws Middlewares) Handler(h http.Handler) http.Handler

Handler builds and returns a http.Handler from the chain of middlewares, with `h http.Handler` as the final handler.

func (Middlewares) HandlerFunc

func (mws Middlewares) HandlerFunc(h http.HandlerFunc) http.Handler

HandlerFunc builds and returns a http.Handler from the chain of middlewares, with `h http.Handler` as the final handler.

type Mux

type Mux struct {
	// contains filtered or unexported fields
}

Mux is a simple HTTP route multiplexer that parses a request path, records any URL params, and executes an end handler. It implements the http.Handler interface and is friendly with the standard library.

Mux is designed to be fast, minimal and offer a powerful API for building modular and composable HTTP services with a large set of handlers. It's particularly useful for writing large REST API services that break a handler into many smaller parts composed of middlewares and end handlers.

func NewMux

func NewMux() *Mux

NewMux returns a newly initialized Mux object that implements the Router interface.

func NewRouter

func NewRouter() *Mux

NewRouter returns a new Mux object that implements the Router interface.

func (*Mux) Connect

func (mx *Mux) Connect(pattern string, handlerFn http.HandlerFunc)

Connect adds the route `pattern` that matches a CONNECT http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Delete

func (mx *Mux) Delete(pattern string, handlerFn http.HandlerFunc)

Delete adds the route `pattern` that matches a DELETE http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) FileServer added in v1.0.0

func (mx *Mux) FileServer(path string, root http.FileSystem)

FileServer conveniently sets up a http.FileServer handler to serve static files from a http.FileSystem.

func (*Mux) Get

func (mx *Mux) Get(pattern string, handlerFn http.HandlerFunc)

Get adds the route `pattern` that matches a GET http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Group

func (mx *Mux) Group(fn func(r Router)) Router

Group creates a new inline-Mux with a fresh middleware stack. It's useful for a group of handlers along the same routing path that use an additional set of middlewares. See _examples/.

func (*Mux) Handle

func (mx *Mux) Handle(pattern string, handler http.Handler)

Handle adds the route `pattern` that matches any http method to execute the `handler` http.Handler.

func (*Mux) HandleFunc

func (mx *Mux) HandleFunc(pattern string, handlerFn http.HandlerFunc)

HandleFunc adds the route `pattern` that matches any http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Head

func (mx *Mux) Head(pattern string, handlerFn http.HandlerFunc)

Head adds the route `pattern` that matches a HEAD http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) MethodNotAllowed

func (mx *Mux) MethodNotAllowed(handlerFn http.HandlerFunc)

MethodNotAllowed sets a custom http.HandlerFunc for routing paths where the method is unresolved. The default handler returns a 405 with an empty body.

func (*Mux) MethodNotAllowedHandler

func (mx *Mux) MethodNotAllowedHandler() http.HandlerFunc

MethodNotAllowedHandler returns the default Mux 405 responder whenever a method cannot be resolved for a route.

func (*Mux) Middlewares

func (mx *Mux) Middlewares() Middlewares

func (*Mux) Mount

func (mx *Mux) Mount(pattern string, handler http.Handler)

Mount attaches another http.Handler or chi Router as a subrouter along a routing path. It's very useful to split up a large API as many independent routers and compose them as a single service using Mount. See _examples/.

Note that Mount() simply sets a wildcard along the `pattern` that will continue routing at the `handler`, which in most cases is another chi.Router. As a result, if you define two Mount() routes on the exact same pattern the mount will panic.

func (*Mux) NotFound

func (mx *Mux) NotFound(handlerFn http.HandlerFunc)

NotFound sets a custom http.HandlerFunc for routing paths that could not be found. The default 404 handler is `http.NotFound`.

func (*Mux) NotFoundHandler

func (mx *Mux) NotFoundHandler() http.HandlerFunc

NotFoundHandler returns the default Mux 404 responder whenever a route cannot be found.

func (*Mux) Options

func (mx *Mux) Options(pattern string, handlerFn http.HandlerFunc)

Options adds the route `pattern` that matches a OPTIONS http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Patch

func (mx *Mux) Patch(pattern string, handlerFn http.HandlerFunc)

Patch adds the route `pattern` that matches a PATCH http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Post

func (mx *Mux) Post(pattern string, handlerFn http.HandlerFunc)

Post adds the route `pattern` that matches a POST http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Put

func (mx *Mux) Put(pattern string, handlerFn http.HandlerFunc)

Put adds the route `pattern` that matches a PUT http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Route

func (mx *Mux) Route(pattern string, fn func(r Router)) Router

Route creates a new Mux with a fresh middleware stack and mounts it along the `pattern` as a subrouter. Effectively, this is a short-hand call to Mount. See _examples/.

func (*Mux) Routes

func (mx *Mux) Routes() []Route

func (*Mux) ServeHTTP

func (mx *Mux) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP is the single method of the http.Handler interface that makes Mux interoperable with the standard library. It uses a sync.Pool to get and reuse routing contexts for each request.

func (*Mux) Trace

func (mx *Mux) Trace(pattern string, handlerFn http.HandlerFunc)

Trace adds the route `pattern` that matches a TRACE http method to execute the `handlerFn` http.HandlerFunc.

func (*Mux) Use

func (mx *Mux) Use(middlewares ...func(http.Handler) http.Handler)

Use appends a middleware handler to the Mux middleware stack.

The middleware stack for any Mux will execute before searching for a matching route to a specific handler, which provides opportunity to respond early, change the course of the request execution, or set request-scoped values for the next http.Handler.

func (*Mux) With

func (mx *Mux) With(middlewares ...func(http.Handler) http.Handler) Router

With adds inline middlewares for an endpoint handler.

type Route

type Route struct {
	Pattern   string
	Handlers  map[string]http.Handler
	SubRoutes Routes
}

type Router

type Router interface {
	http.Handler
	Routes

	// Use appends one of 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)

	// 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)
}

Router consisting of the core routing methods used by chi's Mux, using only the standard net/http.

type Routes

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
}

Routes interface adds two methods for router traversal, which is also used by the `docgen` subpackage to generation documentation for Routers.
