# node-gzip
> Gzip and ungzip in Node.js
Tiny and easy to use wrapper around [zlib.gzip](https://nodejs.org/api/zlib.html#zlib_zlib_gzip_buffer_options_callback) and [zlib.gunzip](https://nodejs.org/api/zlib.html#zlib_zlib_gunzip_buffer_options_callback) to support promises.
```js
const compressed = await gzip('Hello World');
```
## Install
```sh
npm install node-gzip --save
```
## Examples
#### With Promises
```js
const {gzip, ungzip} = require('node-gzip');
gzip('Hello World')
.then((compressed) => {
return ungzip(compressed);
})
.then((decompressed) => {
console.log(decompressed.toString()); //Hello World
});
```
#### With async / await
```js
const {gzip, ungzip} = require('node-gzip');
const compressed = await gzip('Hello World');
const decompressed = await ungzip(compressed);
console.log(decompressed.toString()); //Hello World
```
## Options
Pass options just like with [Zlib](https://nodejs.org/api/zlib.html). See all [options](https://nodejs.org/api/zlib.html#zlib_class_options).
```js
await gzip('Hello World', {...});
```
## Description
#### gzip(input[,options])
* input: `Buffer | TypedArray | DataView | ArrayBuffer | string`
* returns: `Buffer`
#### ungzip(input[,options])
* input: `Buffer | TypedArray | DataView | ArrayBuffer | string`
* returns: `Buffer`
Use `toString()` after `ungzip` to convert the Buffer into a string.
Supports Node.js version 0.12 and higher.
