log

Package log provides a handler that logs each request/response (time, duration, status, method, path).
The log formatting can either be couloured or not.

Installing

1. Get package:

   go get -u github.com/gowww/log

2. Import it in your code:

   import "github.com/gowww/log"

Usage

To wrap an http.Handler, use Handle:

mux := http.NewServeMux()

mux.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
	fmt.Fprint(w, "Hello")
})

http.ListenAndServe(":8080", log.Handle(mux, nil))

To wrap an http.HandlerFunc, use HandleFunc:

http.Handle("/", log.HandleFunc(func(w http.ResponseWriter, r *http.Request) {
	fmt.Fprint(w, "Hello")
}, nil))

http.ListenAndServe(":8080", nil)

All in all, make sure to include this handler above any other handler to get accurate performance logs.

Colorized output

If you are on a Unix-based OS, you can get a colorized output:

log.Handle(handler, &log.Options{
	Color: true,
})
