Minirouter

go get github.com/ofux/minirouter

Minirouter just adds support for middlewares on top of httprouter. It was inspired by hitch, but minirouter also supports clean definition of sub-paths so that routes can be grouped together.

It is designed to use only standard interfaces such as http.Handler and http.HandlerFunc to define handlers and middlewares, and exclusively uses context to retrieve query parameters. It does not pollute your code with weird custom stuff. Only standard interfaces.

Usage

package main

import (
	"fmt"
	"net/http"
	"log"

	"github.com/ofux/minirouter"
	"github.com/rs/cors"
)

func Index(w http.ResponseWriter, r *http.Request) {
	fmt.Fprint(w, "Welcome!\n")
}

func Hello(w http.ResponseWriter, r *http.Request) {
	fmt.Fprintf(w, "hello, %s!\n", minirouter.Params(r).ByName("name"))
}

func GetUser(w http.ResponseWriter, r *http.Request) {
	fmt.Fprintf(w, "hello, user with ID %s!\n", minirouter.Params(r).ByName("id"))
}

func CreateUser(w http.ResponseWriter, r *http.Request) {
	//TODO: do your thing
}

func checkIsAdmin(next http.Handler) http.Handler {
	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		//TODO: check logged user is admin
		next.ServeHTTP(w, r)
	})
}

func main() {
	mr := minirouter.New()
	mr = mr.WithMiddleware(cors.Default().Handler)

	mr.GET("/", Index)
	mr.GET("/hello/:name", Hello)

	mrAdmin := mr.WithBasePath("/admin").WithMiddleware(checkIsAdmin)
	mrAdmin.GET("/users/:id", GetUser)
	mrAdmin.POST("/users", CreateUser)

	log.Fatal(http.ListenAndServe(":8080", mr))
