Installation & Usage

npm install react-context --save

Wrap Root

Wrap your top-most component with react-context.

var React = require('react');
var context = require('react-context');

var Root = React.createClass({
  render() {
    return <div>Root</div>
  }
});

module.exports = context(Root);

Set Types

Pass it an array of types you want to subscribe to, or call it with no arguments to subscribe to all of them.

// Subscribe to scroll and adBlock
Child.contextTypes = context.subscribe(['scroll', 'adBlock']);

// Subscribe to every context
Child.contextTypes = context.subscribe();
