Bon is fast http router of Go designed by Patricia tree

Features

• Lightweight
• Middleware framework
• Not use third party package
• Standard http request handler
• Flexible routing

Match Patterns

Priority high order

1. static is exact match
   • /users/taro
2. param is directorys range match
   • /users/:name
3. any is all range match
   • /*

package main

import (
	"net/http"

	"github.com/nissy/bon"
)

func main() {
	r := bon.NewRouter()

	r.Get("/users/taro", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("static"))
	})
	r.Get("/users/:name", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("param name is " + bon.URLParam(r, "name")))
	})
	r.Get("/*", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("any"))
	})

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

Example

• Group is inherits middleware and grants a prefix
• Route is does not inherit middleware

package main

import (
	"net/http"

	"github.com/nissy/bon"
	"github.com/nissy/bon/middleware"
)

func main() {
	r := bon.NewRouter()

	v := r.Group("/v1")
	v.Use(
		middleware.CORS(middleware.AccessControlConfig{
			AllowOrigin:      "*",
			AllowCredentials: false,
			AllowMethods: []string{
				http.MethodGet, http.MethodPost, http.MethodPut, http.MethodDelete, http.MethodOptions,
			},
			AllowHeaders: []string{
				"Authorization",
			},
			ExposeHeaders: []string{
				"link",
			},
			MaxAge: 86400,
		}),
	)
	v.Options("*", func(w http.ResponseWriter, r *http.Request) {
		w.WriteHeader(http.StatusNoContent)
	})
	v.Get("/users/:name", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("Hallo," + bon.URLParam(r, "name")))
	})

	admin := r.Group("/admin")
	admin.Use(
		middleware.BasicAuth([]middleware.BasicAuthUser{
			{
				Name:     "name",
				Password: "password",
			},
		}),
	)
	admin.Get("/users/:name", func(w http.ResponseWriter, r *http.Request) {
		w.Write([]byte("Hallo, " + bon.URLParam(r, "name")))
	})

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

Benchmarks

GitHub

The GitHub API is rather large, consisting of 203 routes. The tasks are basically the same as in the benchmarks before.
