Anyway to compress HTML output with Martini? - go

Question

In a quasi-embedded environment so speed is everything. I have found that if I compress my .html files, the app is speedier. Is there a flag or way in Martini to do this on the fly?

Answer 1

You can use gzip Middleware
https://github.com/codegangsta/martini-contrib/tree/master/gzip
import (
"github.com/codegangsta/martini"
"github.com/codegangsta/martini-contrib/gzip"
)
func main() {
m := martini.Classic()
// gzip every request
m.Use(gzip.All())
m.Run()
}

Answer 2

This answer is just to show that #fabrizioM's answer actually works:
Step 1: Create the server
package main
import (
"github.com/codegangsta/martini"
"github.com/codegangsta/martini-contrib/gzip"
)
func main() {
m := martini.Classic()
// gzip every request
m.Use(gzip.All())
m.Get("/hello", func() string {
return "Hello, World!"
})
m.Run()
}
Step 2: Run the server
go run main.go
Step 3: Try the server
This is the step where you must remember to include the Accept-Encoding: gzip header (or equivalent).
Without compression:
curl --dump-header http://localhost:3000/hello
HTTP/1.1 200 OK
Date: Wed, 09 Jul 2014 17:19:35 GMT
Content-Length: 13
Content-Type: text/plain; charset=utf-8
Hello, World!
With compression:
curl --dump-header http://localhost:3000/hello -H 'Accept-Encoding: gzip'
HTTP/1.1 200 OK
Content-Encoding: gzip
Content-Type: text/plain; charset=utf-8
Vary: Accept-Encoding
