The gist of Deep Storage

1. Create a new Deep Storage instance and initialise its state

import { deepStorage } from 'deep-storage';

const storage = deepStorage({
    timer: 0
});

2. Create a view that responds to changes in state

import { wire } from 'deep-storage-react';

class TimerView extends React.Component {
    render() {
        return (
            <button onClick={this.onReset.bind(this)}>
                Seconds passed: {this.props.timer}
            </button>
        );
    }
    onReset () {
        this.props.resetTimer();
    }
};

const DeepTimerView = wire(TimerView, {timer: storage.deep('timer')});

ReactDOM.render((
    <DeepTimerView resetTimer={resetTimer}/>
), document.body);

3. Modify the State

function resetTimer() {
    storage.deep('timer').set(0);
}

setInterval(function tick() {
    storage.deep('timer').update(prev => prev + 1);
}, 1000);
