WebStorm 9 released with improved Dart support

Today, JetBrains announced WebStorm 9, an update to their powerful web development editor. Highlights for the Dart developer include: pub serve support, improved isolates debugging, Observatory support, new syntax support, and more.

WebStorm 9 now launches pub serve, Dart's development server, when the developer runs a Dart web app. Pub serve takes care of generating assets, compiling to JavaScript, and more.

Developing and debugging apps that run multiple computations in parallel is now easier, thanks to the new ability to set breakpoints inside of isolates.



For deep insight into your app running on the Dart VM, you can now open the Observatory directly from WebStorm 9. Use the Observatory to learn how memory is used, where CPU time is spent, and more.



It's now easier to debug apps that use collections (which is every app), thanks to the debugger's logical view of maps and lists. Developers now see the logical data structure instead of internal implementation details.



WebStorm 9 now understands syntax for deferred loading and symbols. Deferred loading helps web apps start quickly, by delaying when libraries are loaded. Symbols are used when an identifier needs to remain unmodified after minification.

We encourage you to try WebStorm or IntelliJ IDEA for your Dart development, and we hope you enjoy these new features. We look forward to your feedback.

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…

AngularDart 2.1 and new Components

AngularDart got its own dedicated team 5 months ago. Last month, we launched 2.0 final on the Dart Developer Summit. Today, we’re releasing the first minor release after that: 2.1.

Since the focus of AngularDart is Productivity, Performance, Stability, there are no major breaking changes (see the changelog) — but a lot of behind-the-scenes improvements. Your apps will get slightly smaller and faster (even relative to 2.0 which already made huge strides in size and performance since the compiled-from-TypeScript days).

Many features that AngularJS had to implement for JavaScript and TypeScript are not needed in Dart (because Dart already has those features out-of-the-box). So we’re removing them from AngularDart. Renderer is deprecated in favor of plain-old dart:html. NgPlural is going away — Dart programs can use the package:intl library.

New components

On the Dart Developer Summit, we launched AngularDart Components — the material design widgets Google is using in customer-facing apps …
