global-key-value-store v1.1.2

Global Key Value Store

Small and lightweight key value store that makes the stored values globally available. This works in Node.js as well as in the browser across modules and Javascript files. Each value can be assigned to a key. Multi-values are also supported via a separate API. A callback API can be used to receive notifications when values are changed or removed.

Install

npm i global-key-value-store

Examples

Set, get and remove a single value

const store = require('global-key-value-store');

store.set('message', 'Hello World!');
console.log(store.get('message')); // Hello World!

store.remove('message');
console.log(store.get('message')); // undefined

Set, get and remove multiple values for a key

const store = require('global-key-value-store');

store.push('messages', 'Hello World!');
store.push('messages', 'Goodbye!');
console.log(store.get('messages')); // [ Hello World!, Goodbye! ]

store.remove('messages');
console.log(store.get('messages')); // undefined

Clear all values

const store = require('global-key-value-store');
store.clear();

Subscribe and unsubscribe callback functions

const store = require('global-key-value-store');

var callback = () => console.log('Message has changed!');
store.subscribe('message', callback);

store.set('message', 'Hello World!'); // Message has changed!
store.set('message', 'Goodbye!'); // Message has changed!

store.unsubscribe('message', callback);
store.remove('message'); // (silent)
