Collection of middlewares in Go

Middlewares

accesslogs

HTTP access logs middleware

Router-wide access logs:

package main

import (
	"log"
	"net/http"

	"github.com/TwiN/go-middlewares/accesslogs"
)

var exampleHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
	w.WriteHeader(http.StatusOK)
	w.Write([]byte("pong"))
})

func main() {
	router := http.NewServeMux()
	router.Handle("/health", exampleHandler)
	router.Handle("/hello", exampleHandler)
	router.Handle("/world", exampleHandler)
	routerWithAccessLogs := accesslogs.New().WithColors().SkipPathsWithDots().IgnorePaths("/health").Handler(router)
	log.Fatal(http.ListenAndServe(":8080", routerWithAccessLogs))
}

You can also use it on a per-handler basis if you wish:

package main

import (
	"log"
	"net/http"

	"github.com/TwiN/go-middlewares/accesslogs"
)

var exampleHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
	w.WriteHeader(http.StatusOK)
	w.Write([]byte("pong"))
})

func main() {
	accessLogs := accesslogs.New().WithColors()
	http.Handle("/hello", accessLogs.Handler(exampleHandler))
	http.Handle("/world", accessLogs.Handler(exampleHandler))
	log.Fatal(http.ListenAndServe(":8080", nil))
}
