Bxog is a simple and fast HTTP router for Go (HTTP request multiplexer).

Usage

An example of using the multiplexer:

package main

import (
	"io"
	"net/http"

	bx "github.com/claygod/Bxog"
)

// Handlers
func IHandler(w http.ResponseWriter, req *http.Request, r *bx.Router) {
	io.WriteString(w, "Welcome to Bxog!")
}
func THandler(w http.ResponseWriter, req *http.Request, r *bx.Router) {
	params := r.Params(req, "/abc/:par")
	io.WriteString(w, "Params:\n")
	io.WriteString(w, " 'par' -> "+params["par"]+"\n")
}
func PHandler(w http.ResponseWriter, req *http.Request, r *bx.Router) {
	// Getting parameters from URL
	params := r.Params(req, "country")
	io.WriteString(w, "Country:\n")
	io.WriteString(w, " 'name' -> "+params["name"]+"\n")
	io.WriteString(w, " 'capital' -> "+params["city"]+"\n")
	io.WriteString(w, " 'valuta' -> "+params["money"]+"\n")
	// Creating an URL string
	io.WriteString(w, "Creating an URL from the current route (This is an example of creating an another URL):\n")
	io.WriteString(w, r.Create("country", map[string]string{"name": "Russia", "city": "Moscow", "money": "rouble"}))
}

// Main
func main() {
	m := bx.New()
	m.Add("/", IHandler)
	m.Add("/abc/:par", THandler)
	m.Add("/country/:name/capital/:city/valuta/:money", PHandler).
		Id("country"). // For a convinience you can indicate a short ID
		Method("GET")  // It is not necessary to indicate the GET method here as the GET method is used by default but this way is used to set an allowed method
	m.Test()
	m.Start(":9999")
}

Settings

Necessary changes in the configuration of the multiplexer can be made in the configuration file config.go

Perfomance

Bxog is the fastest router, showing the speed of query processing. Its speed is comparable to the speed of the popular multiplexers: Bone, Httprouter, Gorilla, Zeus. The test is done on a computer with a i3-6320 3.7GHz processor and 8 GB RAM. In short (less time, the better):

Bxog 163 ns/op
HttpRouter 183 ns/op
Zeus 12302 ns/op
GorillaMux 14928 ns/op
GorillaPat 618 ns/op
Bone 47333 ns/op

API

Methods:

New - create a new multiplexer
Add - add a rule specifying the handler (the default method - GET, ID - as a string to this rule)
Start - start the server indicating the listening port
Params - extract parameters from URL
Create - generate URL of the available options
Shutdown - graceful stop the server
Stop - aggressive stop the server
Test - Start analogue (for testing only)

Example: m := bxog.New() m.Add("/", IHandler)

Named parameters

Arguments in the rules designated route colon. Example route: /abc/:param , where abc is a static section and :param - the dynamic section(argument).

Static files

The directory path to the file and its nickname as part of URL specified in the configuration file. This constants FILE_PREF and FILE_PATH
