+# srcset
+
+> Parse and stringify the HTML `<img>` [srcset](https://www.smashingmagazine.com/2013/08/webkit-implements-srcset-and-why-its-a-good-thing/) attribute.
+
+Can be useful if you're creating a build-tool.
+
+## Install
+
+```
+$ npm install srcset
+```
+
+## Usage
+
+How an image with `srcset` might look like:
+
+```html
+<img
+	alt="The Breakfast Combo"
+	src="banner.jpg"
+	srcset="banner-HD.jpg 2x, banner-phone.jpg 100w"
+>
+```
+
+Then have some fun with it:
+
+```js
+const srcset = require('srcset');
+
+const 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-super-HD.jpg',
+	density: 3
+});
+
+const stringified = srcset.stringify(parsed);
+console.log(stringified);
+/*
+banner-HD.jpg 2x, banner-phone.jpg 100w, banner-super-HD.jpg 3x
+*/
+```
+
+## API
+
+### .parse(string, options?)
+
+Parse the HTML `<img>` [srcset](http://mobile.smashingmagazine.com/2013/08/21/webkit-implements-srcset-and-why-its-a-good-thing/) attribute.
+
+Accepts a “srcset” string and returns an array of objects with the possible properties: `url` (always), `width`, `height`, and `density`.
+
+#### string
+
+Type: `string`
+
+A “srcset” string.
+
+#### options
+
+Type: `object`
+
+##### strict
+
+Type: `boolean`\
+Default: `false`
+
+When enabled, an invalid “srcset” string will cause an error to be thrown. When disabled, a best effort will be made to parse the string, potentially resulting in invalid or nonsensical output.
+
+### .stringify(SrcSetDefinitions, options?)
+
+Stringify `SrcSetDefinition`s. Accepts an array of `SrcSetDefinition` objects and returns a “srcset” string.
+
+#### srcsetDescriptors
+
+Type: `array`
+
+An array of `SrcSetDefinition` objects. Each object should have a `url` field and may have `width`, `height` or `density` fields. When the `strict` option is `true`, only `width` or `density` is accepted.
+
+#### options
+
+Type: `object`
+
+##### strict
+
+Type: `boolean`
+
+Default: `false`
+
+Enable or disable validation of the SrcSetDefinitions. When true, invalid input will cause an error to be thrown. When false, a best effort will be made to stringify invalid input, likely resulting in invalid srcset value.
