AngularDart: The best Angular for you?

Ferhat and Matan recently announced the release of AngularDart 2.0 with some pretty dramatic performance improvements at the Dart Developer Summit in Munich.


We figured we’d have a chat with them to better understand — straight from the horse’s mouth — what this means for developers looking to write a web app.


What is the single most important reason for people to try out the new AngularDart 2.0 release?

That would be better performance. And really — as we talked about at the Dart Summit recently — AngularDart is mainly about providing developers with three things: Productivity, Performance, and Stability.
  • AngularDart is an amazing framework for building web apps and we have internal teams reporting doubling their productivity.
  • With the new release just out, AngularDart output is 40% smaller and 10% faster.
  • Finally, with major teams depending on the framework for their products, we work hard to ensure stability throughout when implementing these improvements.

Indeed, you announced some pretty awesome performance improvements both in terms of output size and speed. What were the key insights that allowed you make so dramatic improvements in such a short time?

For size improvements, it was a combination of low hanging fruit like better whitespace compression, a focus on generating idiomatic Dart code, and refactoring to remove dynamic calls and abstraction layers where possible. For runtime performance, we have leveraged strong types and moved from “dirty checking” to a ComponentState model.

AngularDart 2.0 was just released. So I was wondering, is it stable enough that I can start using it today? I mean, you said that it has been used in production for several months. How does that work?

Yes. We have major Ads products relying on this already, and they have been for months. We have thousands of tests to make sure that as we make further performance improvements, nothing breaks along the way.

Awesome. So what is the best place to go if I want to try this out or learn more?

You can check out the video from our presentation at the 2016 Dart Summit. We also have codelabs that help you get started using AngularDart and even one with the new AngularDart components that Ted talked about at the Summit. Finally, angulardart.org is the place to go for the latest info on AngularDart.

Dart in 2016: The fastest growing programming language at Google, 2nd fastest growing in TIOBE Index

Dart was the fastest growing programming language at Google in 2016 with millions of lines of code written. It also made it to TIOBE Index Top 20 this month (see TIOBE's methodology).

It takes time to build something as ambitious as Dart and, in some ways, Dart is still in its infancy. But we're glad the hard work is starting to pay off.

Many thanks to our amazing community!

We're going to celebrate by ... releasing 1.22 next week (as per our usual 6 week release schedule).

The new Google AdSense user interface: built with AngularDart

AdSense is a free, simple way to earn money by placing ads on your website. The team just launched a completely new version of their app for publishers. Read all about it here. We asked Daniel White, the tech lead for the project, some questions because the new UI happens to be built with Dart and Angular2.


AdSense launched way back in 2003. How long is it since the last big redesign?
Last big redesign was called ‘AdSense 3’ and launched about 6 years ago. It was written in Google Web Toolkit (GWT) and the UI has evolved through several iterations - but this is the first ground-up redesign in 6 years. There are a number of long-standing UX issues that we’ve taken the opportunity to solve. A big shout-out to our UX team who’ve been 100% behind this project. We couldn’t have done it without them!

How many software engineers worked on the project?
Purely on the AdSense applications, we have a team of close to 100. Around 25% of them write Dart.

How many lines of code?
We have around 160K LO…

A stronger Dart for everyone

We are constantly asking ourselves:
How do we make developers even more productive when writing Dart apps? We believe that a critical part of the answer to this question is to make strongmode – a sound static type system for Dart – the standard for all Dart developers.

Teams that use Dart to build apps like Soundtrap, AdWords, AdSense, and Greentea say they really enjoy using strong mode features, such as early error detection. In fact, teams that have switched completely to strong mode cite not only early error detection but also better code readability and maintainability as major benefits. We hear this both from small teams and Рeven more so Рfrom large teams with hundreds of developers writing and maintaining millions of lines of Dart code. As Björn Sperber from Soundtrap says,
Strong mode and the smooth integration with IntelliJ is a joy to use and a huge improvement. If you’ve tried out Flutter, you’ve already used strong mode checks from the Dart analyzer.

Given the benefits …
