R2

A minimalist HTTP request routing helper for Go.

The name "R2" stands for "Request Routing". That's all, R2 is just a capable little helper for HTTP request routing, not another fancy web framework that wraps net/http.

R2 is built for people who:

• Think net/http is powerful enough and easy to use.
• Don't want to use any web framework that wraps net/http.
• Don't want to use any variant of http.Handler.
• Want http.ServeMux to have better performance and support path parameters.

Features

• Extremely easy to use
• Blazing fast (see benchmarks)
• Based on radix tree
• Sub-router support
• Path parameter support
• No http.Handler variant
• Middleware support
• Zero third-party dependencies
• 100% code coverage

Installation

Open your terminal and execute

$ go get github.com/aofei/r2

done.

The only requirement is the Go, at least v1.13.

Hello, 世界

Create a file named hello.go

package main

import (
	"fmt"
	"net/http"

	"github.com/aofei/r2"
)

func main() {
	r := &r2.Router{}
	r.Handle("", "/hello/:name", http.HandlerFunc(hello))
	http.ListenAndServe("localhost:8080", r)
}

func hello(rw http.ResponseWriter, req *http.Request) {
	fmt.Fprintf(rw, "Hello, %s\n", r2.PathParam(req, "name"))
}

and run it

$ go run hello.go

then visit http://localhost:8080/hello/世界.
