es-next/compiler.js fails to resolve module after typescript successfully resolves and compiles it

[cdaringe]

What is your Scenario?

I want to:

• use typescript
• use tsconfig::compilerOptions::paths (and tsconfig::extends, but not related to this issue)
• use testcafe

What is the Current behavior?

Internally, the typescript compiler compiles page.test.ts fine. A downstream es-next compiler cannot resolve a module that the typescript compiler resolved.

What is the Expected behavior?

Either not use the es-next compiler, or extend es-next compiler module resolution with paths as used from the typescript compiler.

What is your public website URL? (or attach your complete example)

tiny, minimal reproduction posted here: https://github.com/cdaringe/testcafe-path-resolution-typescript

What is your TestCafe test code?

// test/page.test.ts
import { foo } from "foo";
import { ClientFunction } from "testcafe";

fixture`foo`.page("http://localhost:3333");

const log = ClientFunction(() => console.log("sup"));

test("bar", async (t) => {
  foo();
  await log();
  await t.debug();
});

// src/foo.ts
export const foo = () => "bar";

Your complete configuration file

none, cli only.

DEBUG=testcafe* testcafe --compiler-options='typescript.configPath=tsconfig.json' chrome test/

Hi @cdaringe,

You cannot override the target compiler option in the TypeScript configuration file. However, there is PR that supports native ESM. You can use it once it is merged and published.

hey @Aleksey28 , thx for the reply. i've dropped target from the demo so as to keep this bug report focused on the resolution issue. indeed, i don't need that target, i just used a bunch of the defaults from tsc --init, but i appreciate the tip/ref regardless!

Hi @cdaringe,

You're welcome. I'll close the issue. Feel free to contact us if you have further questions.

[cdaringe]

@Aleksey28 forgive me—the issue should not be closed. The issue should remain open. My above remark was politely stating that your suggestion is not relevant to this specific problem

[Aleksey28]

Ok. In this case, please update your example so that I can run it and reproduce this error.

[cdaringe]

@Aleksey28, the example is updated and runnable, with instructions in the repo. thanks!

[Aleksey28]

I managed to reproduce the issue. We will update this thread once we have any news.

[hendriku]

Thanks for providing a minimal example; I've already spent hours on debugging that in our project. Are there any known workarounds or versions where this bug is not present in?
