type-stripping in Node.js recommendations?

[marcomuser]

Node.js is adding native ts support. It would be great if the Node.js tsconfigs would follow the official recommendations: https://nodejs.org/docs/latest/api/typescript.html#type-stripping

I think we'd need a separate one for that, the type-stripping in node is experimental and requires flagging

I'm not sure those are options that one should be enabling without understanding what you're doing already; those flags are also incomplete until TS adds the ability to block bad syntax and require .ts in imports as well.

A separate tsconfig sounds reasonable! Would you then wait for the tsconfig option mentioned (reference for others: microsoft/TypeScript#59601), or could we go ahead and provide a “strip-types” tsconfig that could be kept in sync with the Node.js recommendations for this mode going forward?

TypeScript 5.8 beta was just released with a new erasableSyntaxOnly option:

It'd be great to see it as part of @tsconfig/strictest.
