> Get the gzipped size of a string or buffer

const text = 'Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.';

Any [`zlib` option](https://nodejs.org/api/zlib.html#zlib_class_options).

Returns a [`stream.PassThrough`](https://nodejs.org/api/stream.html#stream_class_stream_passthrough). The stream emits a `gzip-size` event and has a `gzipSize` property.

Returns a `Promise` for the size of the file.
