"Composite Components"

Declarative markup & events

Bi-directional data binding

Plays nicely with other libs (jQuery, Bootstrap, etc.)

With React, you *never* generate strings. Instead, you construct a tree of lightweight objects that represent HTML elements and subcomponents that make up your component. This tree of objects is eventually serialized to HTML.

Web Components Today!

Native web components are still a little way off.

Luckily (as usual) libraries are leading the way!


Full Web Component polyfill library by Google

<element name="tk-element-databinding">
    This is <strong>{{owner}}</strong>'s tk-element.
    Polymer.register(this, {
      owner: 'Brian'


By Mozilla, mainly focused on custom elements

// JS:
xtag.register('modal', {

// HTML:
  <h3>X-Tags Modal Map</h3>
  <x-map data-key="6c86bb5b30a442c"></x-map>

React Components

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

    <Hello name="World" />, document.body

Angular Components

<input type="text" ng-model="yourName" value="World">

<h1>Hello {{yourName}}!</h1>

Ember Components

App.ApplicationController =
    yourName: "World"

<p>Hello, {{yourName}}!</p>
