# srcset [](https://travis-ci.org/sindresorhus/srcset)
> Parse and stringify the HTML `
` [srcset](http://mobile.smashingmagazine.com/2013/08/21/webkit-implements-srcset-and-why-its-a-good-thing/) attribute.
Useful if you're creating a polyfill, build-tool, etc.
## Install
```
$ npm install --save srcset
```
## Usage
How an image with `srcset` might look like:
```html
```
Then have some fun with it:
```js
var srcset = require('srcset');
var parsed = srcset.parse('banner-HD.jpg 2x, banner-phone.jpg 100w');
console.log(parsed);
/*
[
{ url: 'banner-HD.jpg', density: 2 },
{ url: 'banner-phone.jpg', width: 100 }
]
*/
parsed.push({ url: 'banner-phone-HD.jpg', width: 100, density: 2 });
var stringified = srcset.stringify(parsed);
console.log(stringified);
/*
banner-HD.jpg 2x, banner-phone.jpg 100w, banner-phone-HD.jpg 100w 2x
*/
```
## API
### .parse()
Accepts a srcset string and returns an array of objects with the possible properties: `url` (always), `width`, `height`, `density`.
### .stringify()
Accepts an array of objects with the possible properties: `url` (required), `width`, `height`, `density` and returns a srcset string.
