## API

### `minifyStream(?options)`

Create a new minify stream. Write a Javascript file or bundle to it.
Possible `options` are:

 - `uglify` - An uglify module to use, defaults to [`terser`](https://npmjs.com/package/terser).
   It must have an uglify-compatible `minify()` function.
 - All other options are passed to the `minify()` function as the second parameter.
   See the [terser docs](https://github.com/fabiosantoscode/terser#minify-options) for available options.

`minify-stream` adds inline source maps by default. Use [`exorcist`](https://npmjs.com/package/exorcist)
to extract source maps from the output stream into a separate file. If you don't need source maps, pass
the `sourceMap: false` option to disable them.

```js
minifyStream({ sourceMap: false })
```
