Support "module": "nodenext" in tsconfig.json

[michaelhays]

Describe the feature you'd like to request

With TypeScript 4.7 providing ECMAScript Module Support, we can now set this in our tsconfig.json file for the module option:

{
  "compilerOptions": {
    "module": "nodenext",
  }
}

However, Next.js rejects this value, and overwrites it with "esnext".

#36189 did add support for "moduleResolution": "nodenext", but not "module": "nodenext".

Describe the solution you'd like

Add "nodenext" and "node16" to module.parsedValues:

parsedValues: [
  ts.ModuleKind.ES2020,
  ts.ModuleKind.ESNext,
  ts.ModuleKind.NodeNext,
  ts.ModuleKind.Node16,
  ts.ModuleKind.CommonJS,
  ts.ModuleKind.AMD,
]

I figure there may be other changes necessary to make this work, and that the TypeScript version should be bumped to 4.7+ with it.

Describe alternatives you've considered

I edited writeConfigurationDefaults.js directly in my node_modules for a local project, and it seemed to work.

Relevant aside: I think the discussion at #32237 is a bug that needs to be resolved before this can work as expected. I still haven't been able to import files with the .js extension.

Also, "moduleResolution": "node16" isn't supported, only "node", "node12" or "nodenext".

Are there plans to support it? I'm trying to use a local ES module in my monorepo but it won't resolve without "node16". Even an option to stop Next.js forcibly overwriting the tsconfig.json would be helpful.

@terenceodonoghue Can you post a Replit repro?

👋 @ctjlewis, you can try playing with kachkaev/njt#186 where I attempt to switch a small Next.js 13 project to pure ESM with native Node module resolution. I need to use these two workarounds and it’d be great to see them implemented in Next: #41189 (comment). I’m also unable to use "module": "NodeNext" as mentioned in this issue.

Keeping Next.js aligned with native Node module transpiling and resolution helps keep scripts or tests alongside the app.

Is there some progress on this?
