Google Web Toolkit 1.7

Productivity for developers, performance for users

Writing web apps today is a tedious and error-prone process. Developers can spend 90% of their time working around browser quirks. In addition, building, reusing, and maintaining large JavaScript code bases and AJAX components can be difficult and fragile. Google Web Toolkit (GWT) eases this burden by allowing developers to quickly build and maintain complex yet highly performant JavaScript front-end applications in the Java programming language.

With Google Web Toolkit (GWT), you write your AJAX front-end in the Java programming language which GWT then cross-compiles into optimized JavaScript that automatically works across all major browsers. During development, you can iterate quickly in the same “edit – refresh – view” cycle you’re accustomed to with JavaScript, with the added benefit of being able to debug and step through your Java code line by line. When you’re ready to deploy, GWT compiles your Java source code into optimized, standalone JavaScript files. Easily build one widget for an existing web page or an entire application using Google Web Toolkit.

Write AJAX apps in the Java language, then compile to optimized JavaScript

Unlike JavaScript minifiers that work only at a textual level, the GWT compiler performs comprehensive static analysis and optimizations across your entire GWT codebase, often producing JavaScript that loads and executes faster than equivalent handwritten JavaScript. For example, the GWT compiler safely eliminates dead code — aggressively pruning unused classes, methods, fields, and even method parameters — to ensure that your compiled script is the smallest it can possibly be. Another example: the GWT compiler selectively inlines methods, eliminating the performance overhead of method calls.

Cross-compilation affords you the maintainable abstractions and modularity you need for development without incurring a runtime performance penalty.
