import Value from 'storage-value';

const volume1 = new Value('volume');
console.log(volume1.value); // null
volume1.value = 100;

const volume2 = new Value('volume');
console.log(volume2.value); // 100

volume2.value = 200;
console.log(volume1.value); // 200

use default

import Value from 'storage-value';

const volume = new Value('volume', {default: 30});
console.log(volume.value); // 30

const volume2 = new Value('volume');
console.log(volume); // null
// default value doesn't save storage

volume2.value = 100;
const volume3 = new Value('volume', {default: 50});
console.log(volume3.value); // 100
// when there is storage value, ignore default value

use another storage

import Value from 'storage-value';

const volume = new Value('volume', {storage: sessionStorage});
volume.value = 100;

const volume2 = new Value('volume');
console.log(volume2.value); // null
// default storage is localStorage

const volume3 = new Value('volume', {storage: sessionStorage});
console.log(volume3.value); // 100

use namespace

import Value from 'storage-value';

const createHogeValue = Value.namespace('hoge');
const createFugaValue = Value.namespace('fuga');

const test1 = createHogeValue('test');
test1.value = 100;
const test2 = createFugaValue('test');
