A year ago we released a technology preview of Dart, a project that includes a modern language, libraries and tools for building complex web applications. Today, after plowing through thousands of bug reports and feature requests from the web community, a new, more stable and comprehensive version of Dart is now available and ready to use.



With this version of the Dart SDK, we’ve made several improvements and added many features:

• A faster Dart Virtual Machine that on some Octane tests outperforms even V8.
• A new Dart to JavaScript translator that generates fast and compact output.
• An HTML library that works transparently on modern browsers.
• A library to interoperate with JavaScript code.
• An easy to use editor.
• Pub, a new package manager
• Dartium, a Chromium build with native Dart support.
• A server-side I/O library.
• A language specification describing the Dart semantics, including new features.

Over the following months, we will continue to work hard to evolve the SDK, improve Dart’s robustness and performance, and fine-tune the language while maintaining backwards compatibility.


You can download the Dart Editor from dartlang.org. It comes with a copy of the open-source SDK and Dartium. Thanks again for all your feedback – keep it coming.

Ever since we launched Dart, the structured web programming language, we've heard developers asking for a way to use Dart to connect to Google's most popular APIs and services. Thanks to Google's 20% time policy, I’m working on an open source library that helps Dart developers connect to Google APIs such as Google+, YouTube, URL Shortener, and many more.

My favorite sample showing you how to build web apps with Dart and Google APIs is roulette. This little app will shorten your URL, or if you're lucky, rickroll you.

This library is currently alpha and under active development. Please report all bugs in the issue tracker and ask questions in the discussion forum. Thanks for the feedback, and have fun!

Today's release of the Dart SDK and Editor is the first beta release, and contains performance and productivity improvements across the platform. This latest release helps Dart developers automate code evolution, produce smaller JavaScript code and deploy Dart web apps.

The Editor's analysis engine, responsible for reporting warnings and errors, is completely rewritten and is 20% faster at parsing and analyzing. Now, there’s no need to run all the unit tests just to discover a typo. The Dart Editor watches your back as you type.

In addition, Dart Editor makes it easier for developers to manage an evolving app. Some of the new features include:

• "Rename Library" refactoring
• "Convert Method to Getter" and "Convert Getter to Method" refactorings
• "Import Library" quick fix
• "Create Class" and "Create part" quick fixes

Code completion has also improved. For example, completion is now camelcase aware. Type iE and Dart Editor finds isEmpty.

Compiling Dart to JavaScript now results in smaller code. For example, some Dart programs that use reflection and HTML can compile to JavaScript that is 3.7x smaller than previous compilation sizes.

Dart VM performance has also improved. Compared against the previous release of Dart, DeltaBlue is 33% faster and Tracer is 40% faster. This release also includes full SIMD acceleration in Dart VM.

Finally, deploying a Dart web app is now easier, with the beta pub deploy command. It creates a directory with your app's code and assets and prepares it for hosting on your favorite web server. You can use this command from Dart Editor or the pub command-line utility.

That's just the highlights - there are more improvements across the platform. You can read the full release notes for more details and changes. You can download the latest version of Dart Editor, including everything you need for Dart development, from dartlang.org. We look forward to your feedback!

Sometimes, you only have 5 minutes. Luckily, with the Dart Tips series of short video tutorials, that's all you need to start learning the new Dart language and libraries. In these videos, I show off code samples and examples across the various language features of Dart.

For example, here's a quick demo of the various types of constructors in Dart:



You can check out all the videos, or jump to the topic that most interests you:

1. A simple Dart script
2. Runtime modes
3. Variables
4. Strings, numbers, booleans, oh my!
5. Collections in Dart
6. Functions are fun, Pt 1
7. Functions are fun, Pt 2
8. Control flow statements
9. Exceptions
10. Classes: setters & getters
11. Classes: Constructors

We hope you enjoy these videos about Dart. If you have questions or comments about the videos, or Dart, please join us on the Dart mailing list and on Google+. As we say on Dart Tips, stay sharp!

The Dart team invites you to the first global Dart hackathon, a collaboration between the Dart team and the developer community. Sign up and have fun hacking on Dart to build modern client and server side web apps and libraries.

Current hackathon locations include:

• North America:
• Silicon Valley, California, USA
• South America:
• São Paulo, Brazil
• Europe and Middle East:
• London, England
• Prague, Czech Republic
• Tel Aviv, Israel
• Asia:
• Bacolod City, Philippines
• Chandigarh, India
• Goa, India
• Karnataka, India
• Manipal, India
• New Delhi, India
• Seoul, Korea
• Tokyo, Japan

Hackathon dates vary by location. Check out the full list for the schedule.



The Dart project is still in technology preview, which means you’ll be hacking on early access code, but that’s all part of the fun. We’re eager to see what you build, and we hope you can make it. Register today!

An attractive feature of Web programming is a rapid development cycle. Reloading the application after the source code has changed takes a fraction of a second. We want to offer you that same experience when using Dart, and today we’re making Mac and Linux binaries available that integrate the Dart VM into Chromium.

This technology preview allows you to run your Dart programs directly on the Dart VM in Chromium and avoid a separate compilation step. Over time, these programs will take advantage of the VM’s faster performance and lower startup latency.

Dart has been designed from the start to work with the entire modern web, and we’re simultaneously continuing to improve our fast Dart-to-JavaScript compiler. Both the Dart VM and modern JavaScript engines are first-class targets for Dart.

This release of Chromium with Dart VM integration is a technology preview, and should not be used for day-to-day browsing. After more testing and developer feedback, we plan to eventually include the Dart VM in Chrome.

Today’s release of the Chromium + Dart VM integration is another step forward for the open source "batteries included" Dart platform. Our goal is to help you build complex, high performance apps for the modern web, and we encourage you to try Dart and let us know what you think.


Anton Muhin is an engineer at Google Saint Petersburg who recently worked on making V8 VM and DOM bindings faster and now is working on integrating the Dart VM into Chromium. Before that he worked on the Google Calendar backend.

It took approximately 2000 years for the original Rosetta Stone to be discovered, which helped translate the Egyptian Hieroglyphs. We couldn’t wait that long to bridge the Dart and JavaScript worlds, so today we are releasing the JavaScript to Dart Synonym app.

Like most web developers, we are familiar, comfortable, and productive with JavaScript. We were curious about Dart, and thanks to a recent Dart hackathon, we had the chance to play with the language and libraries. The problem was, as JavaScript developers, we didn’t know how to map common JavaScript idioms to Dart. Hence the idea for this synonym app was born.

We started with the basics that every JavaScript and jQuery developer knows: variables, arrays, functions, classes, DOM manipulation, and many more. Then, with the help of the Dart team, we recorded the corresponding Dart versions of each idiom. To practice what we learned, we wrote this app with Dart.


We hope our app that maps between JavaScript and Dart eases your introduction to Dart and gives you a sense of where the project is going. We know the team is eager to hear your feedback. Don’t hesitate to join the conversation or file a new issue for either Dart or the Synonym app. And remember, Dart isn’t set in stone, so your feedback counts.
