react-picture

React component for rendering responsive images. Attempts to implement <img srcset=...> support in non-compliant browsers, otherwize renders the native <img srcset>. Will eventually support Picture & Source elements.

How to use

npm install react-picture

Then use in your react app like so:

var Img = require('react-picture').Image;
...
   render: function() {
   	  var imgs = '//placebacon.net/200/150 600w, //placebacon.net/300/300 800w';

      return (
      	<Img alt='Your picture description' srcSet={imgs} extra={{className='myImg'}}/>
      );
   }
...

The following properties can be passed to the Image component:

• alt - Required and describes your picture
• srcSet - Required and consists of a string formated like srcset
• extra - Optional object which contains properties that will be put on img tag

Features

• Use <img srcset> when supported
• Implement srcset support for browsers that do not have it, using javascript. Currently missing sizes implementation.
