Problem & Expected behavior

What happened?

I added a custom path into tsconfig.json: "paths": {"@/*": ["./*"]}. Then if I run tsx index.ts in a project directory, all ok. If I run it from other directory, as the linked stackblitz already does (see .stackblitzrc):

cd ..
node-hpyz3n/node_modules/.bin/tsx node-hpyz3n/index.ts

then tsx cannot resolve modules referred to by "@/", e.g. import "@/other.js".

This prevents using tsx as a loader for cli tools of projects that use tsconfig paths, as in:

// cli.ts
#!/usr/bin/env tsx
import "@/other.js"
...

// package.json
{
  "bin": {"my-tool":"cli.ts"},
  ...
}

// shell
$ cd my-project
$ yarn link
$ cd /some/other/path
$ my-tool

This behavior doesn't seem to depend on path template names (@, @src, without @, etc).

What did you expect instead?

For tsx to resolve tsconfig paths based on a resolved project root, e.g. tsconfig.json/compilerOptions/{rootDir,baseUrl}. Or maybe based on tsconfig.json's location.

So, basically, if regular imports work relative to the importing source file, tsconfig-paths imports, being baseUrl-relative in normal circumstances, should work relative to where tsconfig.json thinks the root is. I believe there's no reason to resolve modules outside of a project root.

Do you have an error stack trace?

Do you have documentation links? Do you have screenshots?

Nope.

Duplicates #265 I think

Please fix your reproduction to:

• Remove unnecessary code
• Remove extraneous steps; specifically in your case, move the TS project to a nested dir so you don't need to ask others to run a more complex command.

[sou-long]

Done. A nested dir doesn't work with stackblitz due to path issues, but I modified .stackblitzrc so it takes the described steps and reproduces the issue immediately.
