About this Book

JavaScript at the server? You guess. Node.js is a JavaScript server able to assisting scalable, high-performance internet functions. utilizing asynchronous I/O, the server can do a couple of factor at a time, a key requirement for real-time apps like chat, video games, and reside facts. and because it's JavaScript, you utilize an identical language finish to end.

Node.js in Action indicates you the way to construct production-quality functions. transparent introductions of key recommendations and example-by-example assurance take you from setup to deployment. You'll dive into asynchronous programming, facts garage, and output templating, and engage with the filesystem to create non-HTTP purposes like TCP/IP servers and command-line instruments. ideal for an online developer transitioning from Rails, Django, or personal home page. calls for easy wisdom of JavaScript. No previous adventure with Node.js needed.

These types of optimizations would be much more difficult with regular Ajax applications built directly with JavaScript. The GWT team is also actively working on improving the compiler. You can easily add performance improvements available in new versions of the compiler to your application by simply upgrading to a new GWT version. 3. A smaller application size means the application loads faster in the client’s browser. Evaluating Your Background Now that you know how the Google Web Toolkit fits into the web landscape, let’s consider how your background fits with GWT.

Running the applicationCreator script without specifying a path To start using GWT to build an application, we first need to create a new project. The project is going to be for a Hangman Ajax application, so we’ll use Hangman for the project name. Figure 1-4 shows creating the application’s directory and then running GWT’s applicationCreator script to generate the required files. Figure 1–4. Hangman The argument is the full Java path name for our GWT application. ) The Java path maps directly to a path in the file system, as you can see in Figure 1-4.

In the short term, you just need to learn how to use GWT to build an Ajax application. Fortunately, it’s easy to get started. A Quick Tutorial The best way to get a feel for building applications with GWT is to run through a quick high-level view of building a simple application. This section shows you how to build an Ajax application, including how to start a A Quick Tutorial GWT project, customize the generated code, create a dynamic interface, and load data asynchronously from a server. The application we’ll build, called Hangman, provides an interface to play a game which involves guessing a word.
