localStorage MOVED
=== =====
An inefficient, but as W3C-compliant as possible using only pure JavaScript, `localStorage` implementation. Now at https://github.com/node-browser-compat/dom-storage
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
---
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
