npm packages typed via `*.d.ts` reported as unused about knip HOT 10 CLOSED

I have a similar situation. I have a .js file and I'm using an export from it in a .ts file. When I use the imported function I get typescript errors related to types. For that reason I created a .d.ts that only defines types for the exports in the .js file so I don't have any typescript errors any more.
But... Now knip comlpains about the .js file not being used. IMO this is a bug, because knip should assume, that .d.ts files don't contain any implementation, but rather only definitions.

Works for my version of the issue.

Knip version: 4.5.0
Node.js version: 20.10.0

Seems a PR is in the works for this:
#503

Yet another effect probably from the same reason:

For that reason I created a .d.ts that only defines types for the exports in the .js file so I don't have any typescript errors any more.

In my case exports used only in that .js file are reported as unused (though I haven't been able to reproduce this in a minimized project). Knip version is 5.0.2.

🚀 This issue has been resolved in v5.1.3-canary.0. See Release 5.1.3-canary.0 for release notes.

Would be great if you could try out this version before I'll release v5.1.3 (I'm not in a hurry btw)

@webpro 5.1.3-canary.0 didn't fix it for me :(

It does for me, although I did add an (empty) tsconfig.json to your example.

In my actual project I have this in my tsconfig.json

{
  "compilerOptions": {
    "baseUrl": "src"
  },
  "include": ["./"]
}
