Using LocalStorage with React?

Question

From what I am experiencing so far, it doesn\'t seem like ReactJS updates with the state of localStorage. My code below.

var Frr = React.createClass({
getIni         


        

Answer 1

The .setItem() local storage function returns undefined. You need to perform the local storage update and then return the new state object:

switchoff: function(){
    localStorage.setItem('state', 'off');
    this.setState({lights: 'off'}); 
},
