IN PROGRESS - IN PROGRESS

Introduction

generic_store.js wraps store.js and add :

• an implementation in memory for safe tests or other use
• an (optional) automatic key prefixing for avoiding conflicts (NOT IMPLEMENTED)

NOTE : ONLY set() AND get() ARE IMPLEMENTED FOR NOW !

User Story

In you web app, you use the convenient local storage instead of fat cookies. Of course, you use store.js (https://github.com/marcuswestin/store.js) to access the local storage.

Now there are two problems :

• it's unsafe to unit test your app since local storage is persistent and shared
• you may mess with another local storage user which use the same keys

Solution :

• Have a store.js implementation in memory for tests
• Have an automatic prefixing of keys

Usage

define(
[
	'generic_store/generic_store',
],
function(GenericStore) {
	"use strict";

	// new store, in memory, guaranteed to be empty
	var store1 = GenericStore.make_new("memory");
	// new store, in memory, guaranteed to be empty, different from the previous one
	var store2 = GenericStore.make_new("memory");
	// existing store (local storage), "existing" reminds us that it may already contain data
	var store3 = GenericStore.get_existing("local");

	// now use your store like store.js
	store.set('username', 'marcus');
	store.get('username');
	store.set('user', { name: 'marcus', likes: 'javascript' });
