feathercache's Introduction

โ˜ Feather Cache v0.3

A super-lightweight json cache for your mobile web apps.

Features

  • Provides a thin wrapper around html5 localStorage.
  • Complex data (objects, arrays, et al) are seralized with JSON.stringify so you can store virtually anything.
  • This data is JSON.parse'd on the way out for you too. You're welcome!
  • Written in coffescript.
  • Fully unit tested with Jasmine.

Requirements

  • jQuery 1.4+

Install

  • Include feathercache.js in your webpage.
  • Ensure that jQuery is already included on the page, or FeatherCache#fetch won't work for you.

Usage

fc = FeatherCache({key_prefix: 'feather:'});

fc.set('key','value');
fc.get('key');

fc.fetch('nggyu','http://graph.facebook.com/nggyu');
nggyu = fc.get('nggyu');
console.log(nggyu);

feathercache's Issues

QUOTA_EXCEEDED_ERR - Exception Handling

When saving to the cache, there is a real possibility that the quota could be exceeded. We need to check for this happening and take appropriate action.

An example of detecting this issue is below:

try {
  localStorage.setItem("name", "Hello World!");
} catch (e) {
  if (e == QUOTA_EXCEEDED_ERR) {
    alert('Quota exceeded!');
  }
}
