• What language/extension are you using?
• What does closed reference mean?

[kiyutink]

JavaScript, no extensions.
I didn't mean closed reference, I meant to say that the reference won't be found, if the file with the reference is closed (not opened in the editor)

Do you have a jsconfig.json?

[kiyutink]

hmm, when i add a jsconfig.json it stops finding references even in opened files

Please share a minimal code example or small example project

Hey, I've done some checking and found out that it only happens if you search for references of a variable defined in a .jsx file. Unfortunately, I couldn't find how to configure the project to allow VS Code to enable it. To reproduce this you can just create two files as following:

file1.jsx:
export const a = 3;

file2.jsx:
import {a} from './file1.jsx'

Then if you search for references of 'a' from file1.jsx you'll get different results depending on whether you have or don't have a jsconfig.json. If you don't have it you'll only see the reference of 'a' in file2.jsx if it's opened in the editor. If you have a jsconfig.json, you won't see the reference regardless of the file being opened in the editor or not.

In your jsconfig.json, make sure you set "jsx": "react" under compilerOptions. That should fix the problem
