// First check if your browser has localStorage support 
// Save the JSON data into localStorage 
db.set('key', data); 
// Access the data in the application. The following method returns the Object. 
// Remove the data having key as key, checks for keys with no data. 

Installation and Use:

You can download the latest stable code via bower or npm: With npm you can download with:

npm install ldb or bower install ldb.js

I have also included polyfill.js for enabling localStorage in browsers where there is no support.

<script type="text/javascript" src="polyfill.js"></script>
<script type="text/javascript" src="ldb.js"></script>
