Google Web Toolkit
Google Web Toolkit (GWT) is an open source set of
tools for building and optimizing complex browser-based
applications. Its goal is to enable productive development of
high-performance web applications without the developer having to be an
expert in browser quirks, XMLHttpRequest, and JavaScript. It offers
excellent development tools.
GWT is used by many products at Google, including Google Wave
and the new version of AdWords. Other projects that use GWT include Go
Grid, Lombardi Blueprint, Scenechronize, and Whirled.
Many common widgets not found in the GWT have been implemented
in third-party libraries, such as Ext GWT, GWT Component Library,
GWT-Ext, GWT Widget Library, GWTiger, Rocket GWT, Dojo, and SmartGWT.
Features include:
- A single code base for client and server
- The GWT SDK contains the Java API libraries, compiler, and
development server. It lets you to write client-side applications in
Java and deploy them as JavaScript
- Identify performance problems with Speed Tracer, a
Chrome Extension
- The Plugin for Eclipse provides IDE support for Google Web
Toolkit and App Engine web projects
- GWT Designer lets you create user interfaces with tools for
intelligent layout assist, drag-and-drop, and automatic
code generation
- Dynamic and reusable UI components: programmers can use
pre-designed classes to implement otherwise time-consuming dynamic
behaviors, such as drag-and-drop or sophisticated visual tree structures
- Simple RPC mechanism
- Browser history management
- Support for full-featured Java debugging
- GWT handles some cross-browser issues for the developer
- JUnit integration
- Man mix handwritten JavaScript in the Java
source code using the JavaScript Native Interface (JSNI)
- Support for using Google APIs in GWT applications
(initially, support for Google Gears)
- Design and develop their application in
a pure object-oriented fashion, since they're using Java (instead of
JavaScript) Common JavaScript errors, such as typos and type
mismatches, are caught at compile time
- The JavaScript that the GWT compiler generates can be
tailored to be either unobfuscated and easy to understand or obfuscated
and smaller to download
- A number of libraries are available for GWT, by Google and
third parties. These extend GWT's features
- Animations
- Cookies
- Easy internationalization
