GWT 2.0 is the latest version of Google Web Toolkit, the search giant's open-source development tool kit for building and optimizing complex browser-based applications.
Google has introduced GWT 2.0, the latest version of Google Web Toolkit, the
search giant's "open-source development tool kit used by thousands of
developers ... for building and optimizing complex browser-based
applications," it said in a news release Dec. 9.
Recent "improvements in browser speed and capabilities" enable the
creation of "ever larger and richer Web applications," Google said.
The company announced the release of GWT 2.0 at a Google Campfire One event
held Dec. 8 at Google's headquarters in Mountain View,
In a blog post about the release, Andrew
Bowers, GWT product manager,
said the GWT 2.0 release was designed "to
do two main things for developers: make it easier to build faster apps [and]
speed up the overall development cycle."
"This is a very exciting release
because it's the [culmination] of a year and a half working with teams like
Google Wave, AdWords, and Orkut (among many others inside and outside of
Google) to evolve GWT to meet the needs of today's web applications. There are
many features and improvements, but let me call out three which we're
especially excited about."
The three new features Bowers drew attention to were Speed Tracer, Code
Splitting and UiBinder. The Google news release described them as follows:
"- Performance Profiling with Speed Tracer:
Speed Tracer is a new tool built using modern HTML5 technologies that allows
developers to diagnose performance problems in the browser, providing insight
that hasn't been available before about low-level operations deep within the
Incremental Downloading with Code Splitting: As applications grow
larger, developers want to ensure that their applications start as quickly as
possible, without requiring application "boot up" time as the code
downloads. Code Splitting enables developers to safely and easily slice and
dice their application code so that key functionality can load immediately and
other features can be loaded later as needed.
Declarative UI with UiBinder: Team projects benefit from a workflow that
allows smooth collaboration between designers and developers. UiBinder is a new
declarative UI framework in Google Web Toolkit which enables rapid design iteration
and a clean separation between presentation layer and application logic."
"The Web is getting more powerful as an application platform and ever-improving
developer tools are playing a key role in this growth," the release quoted
Bowers as saying. "Google Web Toolkit's performance and productivity
enhancements have been tried and tested over the past year with Google teams
that are pushing the boundaries of Web apps-
Google Wave and AdWords 3.0."
"We use Google Web Toolkit for all our Java-based internal apps,"
said Google CIO Ben Fried. "It's a
great tool for Enterprise-class Java GUI development, and we build our most
sensitive and critical corporate systems with it. In addition to the big
benefits in developer productivity GWT offers, the future-proofing and browser
independence you get out of the box mean that we're protected from the problems
caused by browser-specific bugs and exploits."
