WebStorm 12 EAP, 144.3891: debugging Web Workers, and more

A fresh WebStorm 12 EAP build (144.3891) is now available for download!

As always, you can download it here or, if you have a previous EAP build (144.3600) installed, you should soon get a notification in the IDE about a patch update.

Debugging web workers

Web Workers allow you to run intensive scripts in the background thread separate from the main execution thread of a web application.

WebStorm JavaScript debugger can now hit breakpoints inside these background workers. You can go through the frames and explore variables the same way as you’re used to. In the drop-down list on the left you can jump between the workers’ threads and the main application thread.


Improvements in Dart support

The update brings more improvements in the Dart support:

  • New options in Generate code (Cmd-N on OS X or Alt-Insert on Windows and Linux) that help to add named constructor and to override toString(), ==() and hashCodedart-generate-code
  • Improvements in the package:test support: now you can run all test suites in a folder right from its context menu
  • Remote debug for Dart command line app is now fixed

--nolazy option in Node.js run/debug configuration

--nolazy option is no longer added to the Node.js run/debug configuration. It was used to ensure that breakpoints are hit reliably in older versions of Node.js. However,  no longer needed for Node.js v4 and v5 and moreover it has negative effects on performance. If you’re using Node.js v0.12,  please add --nolazy explicitly in the Node parameters field in the configuration.

The full list of issues addressed in this EAP build is available in the Release notes.
