sweetreaction

A collection of Sweet.js macros for the excellent React library.

You can use it together with jsx-reader or react.hiccup -- or both if you want some chaos :D

Usage

Something like this:

$ npm install sweet.js jsx-reader sweetreaction
$ sjs -r -l jsx-reader -m sweetreaction example.js

Basically, the sweetreaction npm module has the exported macros, use it with your usual Sweet.js setup.

Example

mixin SetIntervalMixin {
	componentWillMount() {
		this.intervals = [];
	}
	setInterval() {
		this.intervals.push(setInterval.apply(null, arguments));
	}
	componentWillUnmount() {
		this.intervals.map(clearInterval);
	}
}

component TickTock uses SetIntervalMixin {
	initialState {seconds: 0}
	defaultProps {name: "React"}
	componentDidMount() {
		this.setInterval(this.tick, 1000); // Call a method on the mixin
	}
	tick() {
		this.setState({seconds: TickTock.increment(this.state.seconds)});
	}
	render {
    this.unit = 'seconds';
		<p>
			{this.props.name} has been running for {this.state.seconds} {this.unit}.
		</p>
	}
	statics {
		increment(n) { return n + 1; }
	}
}

mount <TickTock /> to document.getElementById('example');

compiles to:

var SetIntervalMixin = {
	componentWillMount: function () {
		this.intervals = [];
	},
	setInterval: function () {
		this.intervals.push(setInterval.apply(null, arguments));
	},
	componentWillUnmount: function () {
		this.intervals.map(clearInterval);
	}
};
var TickTock = React.createClass({
  displayName: 'TickTock',
	mixins: [SetIntervalMixin],
	getInitialState: function () {
		return { seconds: 0 };
	},
	getDefaultProps: function () {
		return { name: 'React' };
	},
	componentDidMount: function () {
		this.setInterval(this.tick, 1000); // Call a method on the mixin
	},
	tick: function () {
		this.setState({ seconds: TickTock.increment(this.state.seconds) });
	},
	render: function () {
    this.unit = 'seconds';
		return React.DOM.p(null, this.props.name, ' has been running for ', this.state.seconds, ' ', this.unit, '.');
	},
	statics: {
		increment: function (n) {
			return n + 1;
		}
	}
});
React.renderComponent(TickTock(null), document.getElementById('example'));
