esm and typescript documentation

there exists docs for esm and typescript separately, both nothing on how to use them together.

A best practice documentation for this would be very helpful.

In tsconfig.json should for example `"module": "NodeNext",` be used?

Start by reading the existing ESM and TypeScript documentation and checking how this Node.js framework currently describes module configuration. Define the supported combination and recommended tsconfig.json settings, then add an example explaining how to use ESM and TypeScript together. Done means the guidance covers the relevant setup without leaving the configuration question unresolved.
