Convert React.js components into Web Components

Compatible with any custom elements implementation or polyfill.

UPD Convert Angular and Backbone views as well with MVC elements project

Example

Using component in HTML

<body>
	<my-react-component items="{window.someArray}"></my-react-component>
</body>

React component definition

/* @jsx React.DOM */
MyComponent = React.createClass({
  render: function() {
    console.log(this.props.items);
    console.log(this.props._content); // original tag contents in a <content>
    return <ul><li>React content</li></ul>;
  }
});

document.registerReact('my-react-component', MyComponent);

Find demo in corresponding folder.

Nesting

Original content of a custom element is injected to component as this.props._content.

<my-react-component>Hello world</my-react-component>

In this case props._content is equal to "Hello world".

Handling attributes change

You may add attributeChanged callback to component in order to handle / modify / filter incoming values.

attributeChanged: function(attributeName, oldValue, newValue) {
    console.log('Attribute ' + attributeName + ' was changed from ' + oldValue + ' to ' + newValue);
    this.props[attributeName] = parseInt(newValue);
}

Communicate via DOM events

You may trigger DOM event from React component by using following snippet:

var event = new CustomEvent('change', {
      bubbles: true
    });
this.getDOMNode().dispatchEvent(event)

Subscribing to DOM events is similar:

this.getDOMNode().addEventListener('change', function(e){...});

NPM and Bower

NPM: reactive-elements
Bower: ReactiveElements

Dependencies

React.js
function.bind and Object.create support or polyfills
Custom elements support or polyfill

Custom elements polyfill behavior

Polyfill binds to DOMContentLoaded in order to process DOM so no custom elements exist until it fired. To prevent this hook into DOMContentLoaded and operate elements on it or after.
