yagm is an acronym of Yet Another Go Mux.
YagmMux uses regular expressions to match an URL. If you're familiar with Django, the patterns match is almost the same.
YagmMux is also very close to http.ServeMux. You can replace your actual http.ServeMux by YagmMux without any problem.
go get github.com/alexandrevicenzi/yagm
You can register your handlers as in http.ServeMux.
mux := yagm.New()
mux.HandleFunc("^/$", homeHandler)
mux.Handle("^/files", http.StripPrefix("/files", http.FileServer(http.Dir("./"))))
mux.HandleFunc("^/(?P<name>[a-zA-Z]+)$", helloHandler)You can get the value of named groups with
params, ok := yagm.Params(request)
value, ok := params["group_name"]or
value, ok := yagm.Param(request, "group_name")package main
import (
"fmt"
"net/http"
"github.com/alexandrevicenzi/yagm"
)
func homeHandler(w http.ResponseWriter, r *http.Request) {
fmt.Fprint(w, "Hello World!")
}
func helloHandler(w http.ResponseWriter, r *http.Request) {
name, ok := yagm.Param(r, "name")
if !ok {
name = "Unknown"
}
fmt.Fprintf(w, "Hello %s!", name)
}
func main() {
mux := yagm.New()
mux.HandleFunc("^/$", homeHandler)
mux.Handle("^/files", http.StripPrefix("/files", http.FileServer(http.Dir("./"))))
mux.HandleFunc("^/(?P<name>[a-zA-Z]+)$", helloHandler)
http.ListenAndServe(":8000", mux)
