Typing of RTK Query createApi return value in JetBrains WebStorm?

[joshuajung]

Hi everyone,

I'm evaluating a switch from VSCode to WebStorm for our frontend development. Everything works great so far, but I'm noticing that all our RTK Query typings are missing in code completion – see the detailed issue at https://youtrack.jetbrains.com/issue/WEB-60736/Return-type-of-createApi-from-redux-toolkit-is-not-correctly-inferred.

May I ask if any of you are using Webstorm for RTK Query development and can or cannot confirm this finding?

Thank you!

Unfortunately, we cannot do much to support WebStorm until they start actually using TypeScript and not their own implementation.

We have type tests that test the library against the last 5 versions of TypeScript to guarantee compatibility, but WebStorm uses some self-invented heuristic that often acts very similar to TypeScript, but oftentimes also completely goes off the rails and does stuff like you see there.

I can really just recommend you to use an IDE for TypeScript development that actually uses the TypeScript language server (VSCode, vim, etc.).

Thanks a lot for the insights! I had no clue that WebStorm had its own TS implementation. I'll probably go back to VSCode for the time being.

I just checked a piece of code against your snippets in YouTrack. Indeed, WS shows the API type as any, but it suggests correctly. Or am I missing something?

Oh, that's an interesting observation. Indeed, autocomplete seems to be working fine when being used inside the same file. When I import the file into another one with a lot of other unrelated TS code though, it only works in about 20% of the cases. Weird. I'll see if I can pin it down an further. Feel a bit like it's hitting some kind of timeout and then just giving up, as code completion is rather slow for this file in VSCode as well.
