To use modeljs in your application copy src/model.js to an appropriate location and include it in your HTML like so:

<script type="text/javascript" src="/path/to/model.js"></script>

If your doing server side development in Node, you can import it like so:

var Model = require("/path/to/model.js");

Or using npm install

npm install modeljs
var Model = require("modeljs");

Examples

A couple of example pages have been created to show how to use modeljs. They can be found in the /test/example folder

• New sandbox enviornment on jsFiddle here.
• tableWidget.js Shows how a table widget can be created with model js.
• example.html Shows how to integrate the table widget on your page and is followed by a tutorial of the modeljs api.
• knockoutExample.html Shows how easy it is to build a binding library on top of modeljs that behaves like the popular knockoutjs library. The example is almost identical to the knockoutjs introduction example.
