Javascript RAM storage

README.md

Random-access memory (RAM) storage for JavaScript

Works similarly to localStorage and sessionStorage but stored in the RAM. However, unlike local and session storage we don't need to serialise objects and arrays before storing.

Store data

var id = Math.random().toString( 36 ).substr( 2, 13 );
ramStorage.setItem( 'randId', id );

Get data

var id = ramStorage.getItem( 'randId' );
// Or...
var id = ramStorage.randId;

Delete data

ramStorage.removeItem( 'randId' );

ramStorage.js

class RamStorage {

	/**
	 * Class constructor, setup empty storage and field proxy
	 */
	constructor() {
		this.storage = {};

		return new Proxy( this, {
			get: function( instance, attribute ) {
				if ( attribute in instance ) {
					return instance[ attribute ];
				} else if ( attribute in instance.storage ) {
					return instance.storage[ attribute ];
				}
			}
		} );
	}

	/**
	 * Store an item with name
	 *
	 * @param {String} name
	 * @param {Mixed} value
	 * @return {Void}
	 */
	setItem( name, value ) {
		this.storage[ name ] = value;
	}

	/**
	 * Get an item by name
	 *
	 * @param {String} name
	 * @return {Mixed}
	 */
	getItem( name ) {
		return this.storage[ name ];
	}

	/**
	 * Delete an item by name
	 *
	 * @param {String} name
	 * @return {Void}
	 */
	removeItem( name ) {
		delete this.storage[ name ];
	}

}

window.ramStorage = new RamStorage();
