Can somone point me to a basic config for running TypeScript in NodeJS ?

I always circle in those errors, it is a fucking nightmare :

Error [ERR_REQUIRE_ESM]: require() of ... not supported.
TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts"
ReferenceError: exports is not defined in ES module scope
SyntaxError: Cannot use import statement outside a module
error TS1378: Top-level 'await' expressions are only allowed when the 'module' option is set to 'es2022'...

How to simply launch some TS with the import of other TS and other packages (who may be mjs) ?

Deno can do it. But it seems that "ts-node" just answer "F_ Y" instead of documenting a troubleshooting solution.

To answer to myself:
https://www.typescriptlang.org/docs/handbook/esm-node.html

relative import paths need full extensions (e.g we have to write import "./foo.js")
This code works in CommonJS modules, but will fail in ES modules because relative import paths need to use extensions. As a result, it will have to be rewritten to use the extension of the output of foo.ts - so bar.ts will instead have to import from ./foo.js.

It would have be nice to have an hint of "use *.js for importing *.ts files in ES module mode...

I discover it an Stack Owerflow response. The TypeScript Handbook can't say "do not use *.ts, nerver. Juste no extention (old mode) or *.js (new mode)
