Brotli Handler

This is a tiny Go package which wraps HTTP handlers to transparently compress the response body using Brotli or Gzip, for clients which support it. Although it's usually simpler to leave that to a reverse proxy (like nginx or Varnish), this package is useful when that's undesirable.

This is the clone of Gorilla compress middleware with Brotli support. The most of the code was copied from the original files.

Install

go get -u github.com/sh7dm/brotlihandler

Usage

Call CompressHandler with any handler (an object which implements the http.Handler interface), and it'll return a new handler which compresses the response with Brotli or gzip as a fallback. For example:

package main

import (
	"io"
	"net/http"
	"github.com/sh7dm/brotlihandler"
)

func main() {
	withoutBr := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		w.Header().Set("Content-Type", "text/plain")
		io.WriteString(w, "Hello, World")
	})

	withBr := brotlihandler.CompressHandler(withoutBr)

	http.Handle("/", withBr)
	http.ListenAndServe("0.0.0.0:8000", nil)
}
