react-timer-mixin
Using bare setTimeout, setInterval, setImmediate and requestAnimationFrame calls is very dangerous because if you forget to cancel the request before the component is unmounted, you risk the callback throwing an exception.
If you include TimerMixin, then you can replace your calls to
setTimeout(fn, 500)
with this.setTimeout(fn, 500)
(just prepend this.
) and
everything will be properly cleaned up for you.
Installation
Install the module directly from npm:
npm install react-timer-mixin
Example
var React = require('react');
var TimerMixin = require('react-timer-mixin');
var Component = React.createClass({
mixins: [TimerMixin],
componentDidMount() {
this.setTimeout(
() => { console.log('I do not leak!'); },
500
);
}
});
