DOMSnap
=================
Offline web pages by persisting DOM to IndexedDB/WebSQL.
Please try the [demo](http://unbug.github.io/DOMSnap/).

How it works
============= 
HTML5 provides LocalStorage, IndexedDB, and [window.caches](https://googlechrome.github.io/samples/service-worker/window-caches/) to build offline web apps.
But all of [these technologies](http://www.html5rocks.com/en/features/offline), we can't miss local database.
DOMSnap takes full advantage of [offline technologies](http://www.html5rocks.com/en/features/offline).
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`](https://github.com/unbug/DOMSnap/tree/master/dist) 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**

```javascript
//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'});
```
