Badger

Simple Route multiplexer for web api's based on httprouter adding the feature to add Middlewares to specific group of routes.

Why a new Router?

Please see the reason here.

Features

• Fast and versatile routing
• Easy to use route grouping
• Middlewares
• 100% stdlib interfaces

How does it work?

Simple server

package main

import (
	"net/http"

	"github.com/hugoluchessi/badger"
)

func main() {
	// Create new Mux
	mux := badger.NewMux()

	// Create new router group
	router := mux.AddRouter("v1")

	// Handler got GET Products
	router.Get("products", http.HandlerFunc(func(res http.ResponseWriter, req *http.Request) {
		products := YourProductsDAL.all
		fmt.Fprintf(res, toJson(products))
	}))

	// Handler got GET Products
	router.Get("products/:id", http.HandlerFunc(func(res http.ResponseWriter, req *http.Request) {
		rp := badger.GetRouteParamsFromRequest(req)
		id, _ := rp.GetInt("id")

		products := YourProductsDAL.where("id = %d", id)
		fmt.Fprintf(res, toJson(products))
	}))

	// Define a middleware used by router 1
	router.Use(func(h http.Handler) http.Handler {
		return http.HandlerFunc(func(rw http.ResponseWriter, req *http.Request) {
			logger.Info("Started")
			h.ServeHTTP(rw, req)
			logger.Info("Finished")
		})
	})

	http.ListenAndServe(":8080", mux)
}
