WebStorm 2020.1 EAP #6: Improvements to Quick Documentation and Support for TypeScript 3.8 Features
WebStorm 2020.1 EAP build #6 is now available!
If you’re unfamiliar with our Early Access Program or if you want to catch up on all the new features, check out our previous EAP blog posts.
The Toolbox App is the easiest way to get the EAP builds and keep both your stable WebStorm version and any EAP versions up to date. Or you can download the EAP builds from our website. You can also choose to be notified right from the IDE when a new EAP build is available: go to Preferences/Settings | Appearance & Behavior | System Settings | Updates and select Automatically check updates for Early Access Program.
Important! WebStorm EAP builds are not fully tested and might be unstable.
Here are some of the highlights of WebStorm 2020.1 EAP #6 (build 201.5985.33). For the full list of issues fixed in this update, see the release notes.
Improvements to quick documentation
We recently made WebStorm show the documentation popup when you hover over a symbol so you can find information about the specific symbols faster. Since this change makes the documentation popup much more visible, we’ve been working on making the information shown in it more actionable.
In particular, WebStorm will now show you information about the type and visibility of the symbol in the same way that it does in the quick definition popup. You’ll also see where the symbol is defined.
Another improvement is that WebStorm will now properly render the information added using custom JSDoc tags and use it for the documentation popup.
Support for TypeScript 3.8 features
WebStorm 2020.1 will introduce full support for the new TypeScript 3.8 features, such as type-only imports/exports, private fields, and top-level `await`. To preview this support, update your project TypeScript version to 3.8. The stable version of Webstorm 2020.1 will have TypeScript 3.8 bundled.
You can also find the syntax-only support for TypeScript 3.8 features in the latest bug-fix update for WebStorm 2019.3, WebStorm 2019.3.3.
That’s it for the most notable highlights. Please report any issues on our issue tracker. And stay tuned for next week’s update!
