HTTP ROUTER

A very lean implementation of http router that supports path param parsing, suitable for most REST implementations. Inspired by httprouter

Usage

package main

import (
	"fmt"
	"github.com/shyamz-22/router"
	"log"
	"net/http"
)

func main() {
	
	rtr := router.New()
	
	rtr.Add("/ping", http.MethodGet, func(w http.ResponseWriter, r *http.Request, params router.PathParams) {
		w.Write([]byte("Pong!"))
	})
	
	rtr.Add("/pings/:id", http.MethodGet, func(w http.ResponseWriter, r *http.Request, params router.PathParams) {
    	id := params.ByName("id")	
    	response := fmt.Sprintf("Pong: %s", id)
		w.Write([]byte(response))
    	})
	
    log.Fatal(http.ListenAndServe(":8080", rtr))
}
