This is a tiny Go package which wraps HTTP handlers to transparently gzip the response body, 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.
go get -u github.com/NYTimes/gziphandlerCall GzipHandler with any handler (an object which implements the
http.Handler interface), and it'll return a new handler which gzips the
response. For example:
package main
import (
"io"
"net/http"
"github.com/NYTimes/gziphandler"
)
func main() {
withoutGz := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/plain")
io.WriteString(w, "Hello, World")
})
withGz := gziphandler.GzipHandler(withoutGz)
http.Handle("/", withGz)
http.ListenAndServe("0.0.0.0:8000", nil)
