Fast and easy-to-use compression package for Go applications.

## Installation

The only requirement is the [Go Programming Language](https://go.dev/dl/).

```sh
$ go get github.com/kataras/compress
```

## Getting Started

Import the package:

```go
package main

import "github.com/kataras/compress"
```

Wrap a handler to enable writing and reading using the best offered compression:

```go
import "net/http"

mux := http.NewServeMux()
// [...]
http.ListenAndServe(":8080", compress.Handler(mux))
```

Wrap any `io.Writer` for writing data using compression with `NewWriter`:

```go
import "bytes"
import "encoding/json"

buf := new(bytes.Buffer)

w, err := compress.NewWriter(buf, compress.GZIP, -1)
if err != nil {
    panic(err)
}

json.NewEncoder(w).Encode(payload{Data: "my data"})

w.Close()
```

Wrap any `io.Reader` for reading compressed data with `NewReader`:

```go
// Where resp.Body is an io.Reader.
r, err := compress.NewReader(resp.Body, compress.GZIP)
if err != nil {
    panic(err)
}
defer r.Close()

body, err := ioutil.ReadAll(r)
```

To retrieve the underline `http.ResponseWriter` please use `w.(*compress.ResponseWriter).ResponseWriter`.

Example Code:
```go
import "net/http"

func handler(w http.ResponseWriter, r *http.Request) {
    target := "/your/asset.js"

if pusher, ok := w.(*compress.ResponseWriter).ResponseWriter.(http.Pusher); ok {
		err := pusher.Push(target, &http.PushOptions{
            Header: http.Header{
                "Accept-Encoding": r.Header["Accept-Encoding"],
        }})
		if err != nil {
			if err == http.ErrNotSupported {
				http.Error(w, "HTTP/2 push not supported", http.StatusHTTPVersionNotSupported)
			} else {
				http.Error(w, err.Error(), http.StatusInternalServerError)
			}
			return
		}
    }
    
    // [...]
}
```

> The `http.CloseNotifier` is obselete by Go authors, please use `Request.Context().Done()` instead.

Supported compression algorithms:

- gzip
- deflate
- brotli
