A little while ago I decided to learn something about game development. Being a die-hard web developer, coding games was something completely new, so I started looking for a good language to learn game development in. Obviously C++ is the most popular language for creating commercial high-end games, but the OpenGL and DirectX API’s were both really hard to understand, especially in an unfamiliar language.

I then came across a book about developing games with Microsoft’s XNA Game Framework using either C# or VB. I quickly learned the C# syntax, which I found out is easy to learn for an (OO) JavaScript developer, and within hours I already had textures flying over my screen controlled by my keyboard and the basics of a simple game.

I then started thinking about how cool it would be to create games just as easily in JavaScript and decided to port the XNA Framework over to JavaScript using Canvas as the rendering device. I quickly had a lot of fun doing so, and learned much about the internals of game development by reverse-engineering the XNA API to JavaScript.

I decided to name the framework GameJS, since I got alot of inspiration from the ExtJS source code. I have always been a fan of ExtJS and the way it is structured.

Based on ComponentArt's Patent-pending Client-side Rendering Technology

The entire Web.UI suite is built on top of ComponentArt's innovative web user interface technology. Rather than using the standard technique of rendering HTML markup through server-side code and sending that content down to the browser, ComponentArt Web.UI controls are designed to generate JavaScript storage arrays containing the minimum data and style information required to display a user interface element. JavaScript logic is then used to generate all the required HTML markup (or DOM elements) on the client. Hence the name of the technology: client-side rendering.

This technique is implemented throughout the entire Web.UI suite, and it carries important technological advantages in several areas:

• Page footprint. The amount of content being sent over the network directly affects application performance. When HTML markup is generated on the server, the amount of output can reach hundreds of kilobytes when complex UI controls are used. As a result of our client-side rendering technology, ComponentArt Web.UI controls generate the smallest page footprint in the industry - up to 10 times lighter than that of competing products.
• Client-side performance. Generating DOM elements on the client as they are needed, and destroying them when they no longer need to be displayed produces significantly better client-side performance than if all DOM elements were pre-generated on the server and existed in the DOM tree at all times. Keeping the DOM tree small produces snappy user experience and provides the ability to handle a large number of user interface elements on the page.
• Client-side APIs. ComponentArt's JavaScript storage-based architecture allows exposing client-side APIs that allow modifying or even creating the structure of UI elements on the client. Since all DOM elements are generated on the fly based on the state of JavaScript storage, exposing such flexible client-side APIs is a natural part of ComponentArt's technology. Please refer to the Technology Showcase demo section for real-live examples involving client-side APIs.
• Rich client-side features. Finally, ComponentArt's client-side rendering technology opens the door for a wealth of rich user interface features that would be impossible or extremely hard to implement with standard, server-based rendering. Examples of these features include: Grid Client Running Mode, AJAX With Client-side Caching and Client-side Binding With Web Services.

It is important to note that all Web.UI controls are also able to generate HTML markup on the server - when needed. Examples when this type of rendering is useful include: support for older browsers, search engine optimization, Visual Studio .NET design-time support, and accessibility support.

What is SwitchPipe? SwitchPipe is a proof of concept "Web application server" or, more accurately, a Web application process manager and request proxy. Backend Web applications are loaded into their own processes, making SwitchPipe language agnostic. HTTP requests are proxied at the TCP level using information extracted from the headers to establish which backend application is being demanded.
