Auto import suggestion across referenced composite projects

[ekr3peeK]

Type: Bug

I am trying to make auto-import suggestions to work when using composite projects via typescripts tsconfig. I've set up a small repo where my issue can be reproduced.

Here is the repo: https://github.com/ekr3peeK/vscode-autoimport-bug

What is happening When trying to use TestClass in a file inside projectA, I get no auto-import suggestions for the class. Auto-import suggestions work for files from which there was something manually imported at least once inside projectA.

What I am expecting I am expecting that if projectA is referencing projectB via tsconfig.json, I should receive auto import suggestion for things exported from projectB, even if no file was added beforehand.

If I add the folder of projectB to the includes inside projectA/tsconfig.json auto-import suggestions work, but the projects are not buildable anymore.

As it seems this is then a typescript related bug (strange, because other typescript features work, only Vs Code fails to suggest auto imports), I will add, that the typescript version that I am using is 5.2.2, but it seems to work with the nightly version. So maybe this was a bug that was already fixed, but not yet released.

I am still not closing this issue, to get a proper feedback about this, thank you!

Okay, so basically this still has some bugs. Auto-import suggestions now work for files that were present at the time VsCode initialized the typescript project. If I add new exports into files that were present, it works and I get suggestions for the new imports as well.

However, if I create a new file in a referenced project, auto-import won't find the exports of the file, until I use the TypeScript: Reload Project option in vs code.

Just to prevent some follow-up questions, I have watch running with build on the parent project, and declaration files are built for the newly created file. So I am not sure if this is a typescript related bug, or a vs code one, some feedback would be nice.

Quick question whether this is still going to be considered in the near future, as it was not included in TS 5.4? For our project we have switched to a monorepo setup with TS Composite Projects and auto-imports don't seem reliable in that setup.

Thanks in advance for any update :)
