[React] React Fundamentals: with-addons - ReactLink

It can be tedious to type out all the boilerplate needed to get the DOM and states in React to synchronize. Luckily, React provides a version of the toolkit with a selection of available addons. This lesson is going to dig into ReactLink, and how this addon can give you two-way binding.

    React.render(<App />, document.getElementById('panel'));

Use addon: ReactLink

1. include the script:

script src="https://fb.me/react-with-addons-0.13.3.js"></script>

2. Add mixin:

mixins: [React.addons.LinkedStateMixin],

3. Use valueLink={this.linkState('name')} instead of 'ref' and 'onChange':

<input valueLink={this.linkState('name')} type="text" placeholder="Name" />
