What is mux ?

mux is a lightweight fast HTTP request router (also called multiplexer or just mux for short) for Go 1.7.

The difference between the default mux of Go's net/http package and this mux is, it's supports variables and regex in the routing pattern and matches against the request method. It also scales better.

Features:

• REGEX URL Matcher
• Vars URL Matcher
• GetVars in handler
• GetQueries in handler
• URL Matcher
• Header Matcher
• Scheme Matcher
• Custom Matcher
• Route Validators
• Http method declaration
• Support for standard lib http.Handler and http.HandlerFunc
• Custom NotFound handler
• Respect the Go standard http.Handler interface
• Routes are sorted
• Context support

Feature request are welcome

Example (Method GET):

    package main

    import (
        "net/http"
        "fmt"
        "os"

        "github.com/donutloop/mux"
    )

    func main() {
        r := mux.Classic()

        //URL: https://localhost:8080/home
        r.HandleFunc(http.MethodGet, "/home", homeHandler)
        
        //URL: https://localhost:8080/home-1
        r.Handle(http.MethodGet, "/home-1", http.HandlerFunc(homeHandler))
        
        //URL: https://localhost:8080/home-2
        r.Get("/home-2", homeHandler)
        
        //URL: https://localhost:8080/home-3
        r.RegisterRoute(http.MethodGet, r.NewRoute().Path("/home-3").HandlerFunc(homeHandler))
        
        //URL: https://localhost:8080/home-4
        r.RegisterRoute(http.MethodGet, r.NewRoute().Path("/home-4").Handler(http.HandlerFunc(homeHandler)))
        
    	errorHandler := func(errs []error) {
            for _ , err := range errs {
                fmt.Print(err)
            }
            if 0 != len(errs) {
                os.Exit(2)
            }
	    }

        r.ListenAndServe(":8080", errorHandler)
    }

    func homeHandler(rw http.ResponseWriter, req *http.Request) {
        //...
        rw.Write([]byte("Hello World!"))
    }

Example (Method POST):

    package main

    import (

        "fmt"
        "os"

        "github.com/donutloop/mux"
    )

    func main() {
        r := mux.Classic()

        //URL: https://localhost:8080/user/create
        r.HandleFunc(http.MethodPost, "/user/create", userHandler)

        //URL: https://localhost:8080/user-1/create
        r.Handle(http.MethodPost, "/user-1/create", http.HandlerFunc(userHandler))

        //URL: https://localhost:8080/user-2/create        
        r.Post("/user-2/create", userHandler)

        //URL: https://localhost:8080/user-3/create
        r.RegisterRoute(http.MethodPost, r.NewRoute().Path("/user-3/create").HandlerFunc(userHandler))

        //URL: https://localhost:8080/user-4/create        
        r.RegisterRoute(http.MethodPost, r.NewRoute().Path("/user-4/create").Handler(http.HandlerFunc(userHandler)))
        
    	errorHandler := func(errs []error) {
            for _ , err := range errs {
                fmt.Print(err)
            }
            if 0 != len(errs) {
                os.Exit(2)
            }
	    }

        r.ListenAndServe(":8080", errorHandler)
    }

    func userHandler(rw http.ResponseWriter, req *http.Request) {

    }

Example (Method GET & Scheme Matcher):
