## Install

```
$ npm install @mole-inc/bin-wrapper
```


## Usage

```js
import {BinWrapper} from '@mole-inc/bin-wrapper';

const base = 'https://github.com/imagemin/gifsicle-bin/raw/master/vendor';
const bin = new BinWrapper()
	.src(`${base}/macos/gifsicle`, 'darwin')
	.src(`${base}/linux/x64/gifsicle`, 'linux', 'x64')
	.src(`${base}/win/x64/gifsicle.exe`, 'win32', 'x64')
	.dest(path.join('vendor'))
	.use(process.platform === 'win32' ? 'gifsicle.exe' : 'gifsicle')
	.version('>=1.71');

(async () => {
	await bin.run(['--version']);
	console.log('gifsicle is working');
})();
```

Get the path to your binary with `bin.path`:

```js
console.log(bin.path);
//=> 'path/to/vendor/gifsicle'
```

> if you have the requested binary installed globally, this one will be used instead (if everything works)
