Usage

Adding values

To add a value to the object, you can either pass it as initial value when creating the store or add it with the setItem method:

import KeysStore from 'mobx-keys-store';

const store = new KeysStore({a: 1});
store.setItem('b', 2);

Since the store is using MobX, the same limitation applies - you should never set properties directly, or they won't be observable.

Getting values

You can get the value directly from the object, or use the getItem method:

console.log(store.a); // 1
console.log(store.getItem('b')); // 2

Updating values

To up[date an existing value, you can either modify it directly or use setItem:

store.a = 3;
store.setItem('b', 4);

The advantage of using setItem is that you don't need to worry if the value is already set - it will be observable in both cases.

Working with numbers

To make working with numbers, there are two helper methods on the store - increaseItem and decreaseItem:

store.increaseItem('a'); // equivalent to store.a++
store.decreaseItem('b', 2); // equivalent to store.b -= 2;

Deleting items

To delete an item, use the removeItem method:

store.removeItem('a');
