DOMSnap
Offline web pages by persisting DOM to IndexedDB/WebSQL.
Please try the demo.
How it works
HTML5 provides LocalStorage, IndexedDB, and window.caches to build offline web apps.
But all of these technologies, we can't miss local database.
DOMSnap takes full advantage of offline technologies.
Storing HTML to local IndexedDB/WebSQL and resumeing when you're offline.
With DOMSnap, web pages can resume to their last state with less request to the server and less template render.
Think offline is a long way out, why not just give DOMSnap a try?
Usage
1.Include dist/DOMSnap.min.js
file in your HTML
<script src="DOMSnap.min.js"></script>
2.Or insttall the package
npm install --save domsnap
and require it in your files
var DOMSnap = require('domsnap');
Examples
//init DOMSnap
var DS = DOMSnap({
onReady: function(){
console.log('DOMSnap is ready');
}
});
//capture snapshot html of #main
DS.capture('#main');
//capture with specified capture id
DS.capture('#main', {id: 'my_id'});
//set the html of #main by it's captured snapshot html
DS.resume('#main');
//set by specified capture id
DS.resume('#main',{id: 'my_id'});
