Warning: Enable project-wide JavaScript/Typescript language features - large codebase

[matyasmihalka]

After upgrade to v2 I am not able to get rid of this error saying To enable project-wide JavaScript/TypeScript language features, exclude large folders with source files that you do not work on.

Note: it's on a large codebase with Vue 2.7.

I noticed one interesting behaviour:

• If I restart VS Code and open a .vue file, the language feature works fine for .vue files but not for .ts.
• If I restart VS Code and open a .ts file, the language feature works fine for .ts files but not for .vue

I tried to add some more exclude patterns like the message suggests, but that didn't help. Also I would not like to go down this road as until now it worked fine.

Is this one still an issue?

[matyasmihalka]

@davidmatter Yes, it's still an issue. I just tried the v2 and I still receive the same warning as before and the above described behaviour is still the same.

Otherwise I am using v1.8.27, that works as expected.

Thank you for reporting. Please provide a minimal reproduction.

I am not sore how to do that in this case. This is happening on project where there are 100 000+ lines of code in Vue and seemingly it's connected with the size of the project.
My experience is that on v2, if I open a Vue file the language feature works fine for that file even if I there is a warning, but if I switch to a .ts file, then it stops working. The behaviour is the same if I do the workflow in the opposite way.

I am also experiencing this on a big Nuxt project.

Something I found is when I change "allowJs": true to "allowJs": false the tsconfig in the .nuxt generated build/dev folder it seems to fix itself.
