+
+> Get the gzipped size of a string or buffer
+
+
+## Install
+
+```
+$ npm install gzip-size
+```
+
+
+## Usage
+
+```js
+const gzipSize = require('gzip-size');
+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.';
+
+console.log(text.length);
+//=> 191
+
+console.log(gzipSize.sync(text));
+//=> 78
+```
+
+
+## API
+
+### gzipSize(input, [options])
+
+Returns a `Promise` for the size.
+
+### gzipSize.sync(input, [options])
+
+Returns the size.
+
+#### input
+
+Type: `string` `Buffer`
+
+#### options
+
+Type: `Object`
+
+Any [`zlib` option](https://nodejs.org/api/zlib.html#zlib_class_options).
+
+### gzipSize.stream([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.
+
+### gzipSize.file(path, [options])
+
+Returns a `Promise` for the size of the file.
+
+#### path
+
+Type: `string`
