compresshandler

Go compress http handler. Just fire and forget.

Package provides methods to wrap http handler for auto decompress compressed data & auto compress response with prefered client compression.

Example

import (
        "net/http"

        "github.com/alexdyukov/compresshandler"
)

func main() {
        echo := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
                w.Write(r.Body)
        })

        compressConfig := compresshandler.Config{
                GzipLevel:        compresshandler.GzipDefaultCompression,
                ZlibLevel:        compresshandler.ZlibDefaultCompression,
                BrotliLevel:      compresshandler.BrotliDefaultCompression,
                MinContentLength: 1400,
        }

        compress := compresshandler.NewNetHTTP(compressConfig)

        http.ListenAndServe(":8080", compress(echo))
}

TODOs

• gin handler
• configurable content response type. We dont need to zip already zipped image or archives:

# default should be:
application/*json
application/*xml
application/*json
*javascript
*ecmascript

• found out better brotli implementation :
