Way
HTTP router for Go 1.7
- Deliberately simple
- Extremely fast
- Route based on HTTP methods and path
- Path parameters via
Context
(e.g./music/:band/:song
) - Trailing
/
matches path prefixes
Install
There's no need to add a dependency to Way, just copy way.go
and way_test.go
into your project, or drop them in:
drop github.com/matryer/way
If you prefer, it is go gettable:
go get github.com/matryer/way
Usage
- Use
NewRouter
to make a newRouter
- Call
Handle
andHandleFunc
to add handlers - Specify HTTP method and path pattern for each route
- Use
Param
function to get the path parameters from the context
func main() {
router := way.NewRouter()
router.HandleFunc("GET", "/music/:band/:song", handleReadSong)
router.HandleFunc("PUT", "/music/:band/:song", handleUpdateSong)
router.HandleFunc("DELETE", "/music/:band/:song", handleDeleteSong)
log.Fatalln(http.ListenAndServe(":8080", router))
}
func handleReadSong(w http.ResponseWriter, r *http.Request) {
band := way.Param(r.Context(), "band")
song := way.Param(r.Context(), "song")
// use 'band' and 'song' parameters...
}
- Prefix matching
To match any path that has a specific prefix, use the ...
prefix indicator:
func main() {
router := way.NewRouter()
router.HandleFunc("GET", "/images...", handleImages)
log.Fatalln(http.ListenAndServe(":8080", router))
}
In the above example, the following paths will match:
-
/images
-
/images/
-
/images/one/two/three.jpg
-
Set
Router.NotFound
to handle 404 errors manually
func main() {
router := way.NewRouter()
router.NotFound = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.WriteHeader(http.StatusNotFound)
fmt.Fprintf(w, "This is not the page you are looking for")
})
log.Fatalln(http.ListenAndServe(":8080", router))
}
Why another HTTP router?
I know, I know. But no routers offer the simplicity of path parameters via Context, and HTTP method matching. Which covers 100% of my use cases so far.
