Support for TypeScript types in JSDoc
We’ll start off with one of the most anticipated improvements – WebStorm now properly supports the TypeScript syntax used within JSDoc comments in your .js files. Support for some syntactic constructs, such as union types, has already been available for a while. With this release, we’ve reworked and expanded the existing support, making WebStorm recognize more syntactic constructs. We’ve also fixed a lot of known issues. For example, optional properties in @typedef declarations are now supported.
Auto-imports for CommonJS modules
The next improvement in this release is for Node.js users. As you may know, WebStorm adds missing import statements as you complete ES6 symbols. It will now do the same for CommonJS modules – require imports will be inserted on code completion.
Whenever the IDE isn’t sure what syntax should be used in a file, it will show you a popup allowing you to choose between using the ES6 and CommonJS syntax.
Generic support for web-types
Synchronized code completion for Code With Me
When you’re in Following mode during a Code With Me session, you can now keep track of what code completion suggestions the person you’re following uses.
Other notable improvements
Those were the biggest highlights. Here are some other important enhancements available in this build:
- We’ve reviewed the list of browsers shown by default in the browser icon popup and removed less popular options. On macOS or Linux, you will no longer see Opera and Edge. The latter is still shown by default on Windows (WEB-50871).
- To avoid potential security issues, the values of variables stored in .env files will no longer be shown during code completion if those files are excluded or added to .gitignore (WEB-46834).
- We’ve fixed the regression bug causing the Stretch to Right / Stretch to Left actions not to work as expected (IDEA-267294).
- On Big Sur, it’s now possible to use a shortcut to switch project tabs (IDEA-259660).
