localdatastore

Unified implementation for saving data in browsers. Gracefully degrades from IndexedDB to WebSQL to Heap.

localdatastore is a fast and simple storage library for JavaScript. It improves the offline experience of your web app by using asynchronous storage (IndexedDB or WebSQL) with a simple API.

localdatastore uses Heap in browsers with no IndexedDB or WebSQL support.

To use localdatastore, just drop a single JavaScript file into your page:

<TBD>
<script src="localdatastore.js"></script>

or install with npm:

npm install localdatastore

This module is compatible with browserify and lasso.

Usage Details

var ds = require('localdatastore');


var selectedDataStore = ds.get();


var resolvedDataStore = ds.get(function() {
    var ua = window.navigator.userAgent.toLowerCase();
    if (ua.indexOf('msie') > -1) {
        return 'heap';
    } else if (ua.indexOf('safari') > -1 && ua.indexOf('chrome') === -1) {
        return 'heap';
    }
    return 'idb';
});


var resolvedDataStore = ds.get('heap');


var database1 = selectedDataStore.init('DB_NAME_1', meta);
