File '@ljharb/tsconfig' not found.

Problem

I was using the 4.0.3 version before but since yesterday it has been reporting an error

The code and module that went wrong have been identified through both projects, but I didn't find out whose dependency this error message is from

qs -> side-channel -> get-intrinsic -> es-errors

jsonwebtoken -> jws -> util

If you use esbuild-loader with the above 2 modules in your project, you get the error

Error: File '@ljharb/tsconfig' not found.

Why is this happening?

• ljharb recently updated packages with a tsconfig.json that extends @ljharb/tsconfig
• esbuild-loader resolving tsconfig.json on dependency imports (bug)

In the minimal reproduction provided above, it's happening because of set-function-length & hasown. You can grep your node_modules for @ljharb/tsconfig to find which packages are causing this.

While these errors started happening as a result of ljharb publishing these tsconfig.json files (which may be an oversight since it's a dev concern), the bug is in esbuild-loader resolving tsconfig files in dependencies.

Solution

The fix should be simple: resolve tsconfig conditionally if the real path is not in node_modules.

Next steps

I'm happy to accept & review a PR. It should contain a test for this case (fake dependency fixture with tsconfig.json).

Locking thread to direct further conversation to PRs.
