AngularDart is going all Dart

Until now, the multiple language flavors of Angular 2 were written as TypeScript source, and then automatically compiled to both JavaScript and Dart. We're happy to announce that we’re splitting the Angular 2 codebase into two flavors – a Dart version and a TypeScript/JavaScript version – and creating a dedicated AngularDart team.

This is amazing news for Dart developers because:

  • The framework will feel more like idiomatic Dart.
  • It will make use of Dart features that couldn't work with the TypeScript flavor.
  • It will be faster.

This is equally great news for our TypeScript and JavaScript developers, by the way. Cleaner API, performance gains, easier contributions. Read more on the Angular blog.

Angular 2 for Dart is used by many teams at Google. Most famously by the AdWords team, but many other Google teams build large, mobile-friendly web apps. Some of the top requests from these teams were: make the API feel like Dart, provide a faster edit-refresh cycle, and improve application performance.

That’s exactly what we aim to do. We believe we can significantly improve both the performance and usability of AngularDart. For example, in the 2 weeks since we started work on the purely Dart version, we were already able to unleash strong mode on the code and were able to significantly improve the code quality (fixed 1000+ warnings).

One more thing


We're also happy to announce plans to release our library of Material Design components for Angular 2 Dart. These components are built purely in Dart, and they’re used in production Google apps. Watch news.dartlang.org for updates.

Here’s just one of the many Angular 2 Dart components we plan to release:



Dart was designed "batteries included" – it’s not just a programming language, but also a set of stable libraries, solid tools, a great framework — and soon, a repository of battle-tested UI widgets.

The components aren’t ready to be publicly released yet, but if you were thinking about learning Dart, now is a good time to start. By the time you’re ready to build production apps, you’ll have the building blocks at your disposal.

Dig into AngularDart


angular2 2.0.0-beta.18 is now available on the pub site. You can look at the source, file issues and create pull requests at dart-lang/angular2. If you already use AngularDart in a project, you can use pub upgrade now to get the latest version. Please join the AngularDart gitter to ask general questions.
