node-extjs

Sencha's (http://www.sencha.com) ExtJS 4 library running under NodeJS (http://www.nodejs.org)

Only includes those objects and components necessary to use ExtJS as a core library with Node.

Also includes some custom extensions to ExtJS to further enhance the library. These are slightly opinionated but work.

This utilizes Node's built-in CommonJS loader system to properly load the necessary ExtJS source files. This retains the full stack trace in errors (other implementations have used eval to load the library).

Installation

(Requires NodeJS 0.6.x or higher)

npm install node-extjs-core

Usage for core

require("node-extjs-core");

console.log(Ext.getVersion().version);

Usage for extended (default)

require("node-extjs-core");

console.log(Ext.getVersion().version);

Ext.define("User", {
    extend: 'Ext.data.Model',

	fields: [
		{name: 'name',     type: 'string'},
		{name: 'age',      type: 'int'},
		{name: 'phone',    type: 'string'},
		{name: 'gender',   type: 'string'},

	changeName: function() {
		var oldName = this.get('name'),
			newName = oldName + " The Barbarian";

		this.set('name', newName);
	}
});

var user = Ext.create("User", {
