DOMStorage

See https://git.coolaj86.com/coolaj86/dom-storage.js for a slightly better version of the same thing.

localStorage

An inefficient, but as W3C-compliant as possible using only pure JavaScript, localStorage implementation.

Purpose

This is meant for the purpose of being able to run unit-tests and such for browser-y modules in node.

Usage

var localStorage = require('localStorage')
, myValue = { foo: 'bar', baz: 'quux' }
;

localStorage.setItem('myKey', JSON.stringify(myValue));
myValue = localStorage.getItem('myKey');

API

* getItem(key)
* setItem(key, value)
* removeItem(key)
* clear()
* key(n)
* length

Tests

null === localStorage.getItem('key');

0 === localStorage.length;
null === localStorage.getItem('doesn't exist');
undefined === localStorage['doesn't exist'];

localStorage.setItem('myItem');
"undefined" === localStorage.getItem('myItem');
1 === localStorage.length;

localStorage.setItem('myItem', 0);
"0" === localStorage.getItem('myItem');

localStorage.removeItem('myItem', 0);
0 === localStorage.length;

localStorage.clear();
0 === localStorage.length;

TODO / Bugs
---

* Does not persist.
* could use fs.readFileSync at load and an occasional fs.writeFile to write-out localStorage.json
* Doesn't not emit Storage events
