Gzip middleware for Negroni.

Mostly a copy of the Martini gzip module with small changes to make it function under Negroni. Support for setting the compression level has also been added and tests have been written. Test coverage is 100% according to go cover.

package main

import (
    "fmt"
    "net/http"

    "github.com/urfave/negroni"
    "github.com/phyber/negroni-gzip/gzip"
)

func main() {
    mux := http.NewServeMux()
    mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
    	  fmt.Fprintf(w, "Welcome to the home page!")
    })

    n := negroni.Classic()
    n.Use(gzip.Gzip(gzip.DefaultCompression))
    n.UseHandler(mux)
    n.Run(":3000")
}

Make sure to include the Gzip middleware above any other middleware that alter the response body.

As noted above, any middleware that alters response body will need to be below the Gzip middleware. If you wish to gzip static files served by the default negroni Static middleware you will need to include negroni.Static() after gzip.Gzip().

    n := negroni.New()
    n.Use(negroni.NewRecovery())
    n.Use(negroni.NewLogger())
    n.Use(gzip.Gzip(gzip.DefaultCompression))
    n.Use(negroni.NewStatic(http.Dir("public")))
