Generating Compile Cache Ahead of Runtime

What is the problem this feature will solve?

It is currently not possible to generate the compile cache without executing the files that will be cached.

Currently, container images and lambda functions can't easily generate code caches ahead of the actual runtime, since the code may have effects you may not want to execute early.

What is the feature you are proposing to solve the problem?

Would it be possible to add a way to generate the compile cache without executing the relevant files, i.e. walking the module tree from the entry point, generating caches along the way?

Perhaps something like node --generate-compile-cache path/to/entrypoint.mjs
and/or

module.generateCompileCache("path/to/entrypoint.mjs")

What alternatives have you considered?

You may be able to work around this by adding "dry-run" code paths specifically for code cache generation, but this is a hacky workaround that can require massive effort.

Beginne damit, das bestehende Compile-Cache-Verhalten von Node.js sowie die vorgeschlagenen Einstiegspunkte --generate-compile-cache und module.generateCompileCache() zu untersuchen. Ermittle, wie der Modulbaum eines Einstiegspunkts durchlaufen werden könnte, ohne Anwendungscode auszuführen. Die Aufgabe ist abgeschlossen, wenn es eine dokumentierte und getestete Möglichkeit gibt, den relevanten Compile-Cache vor der Laufzeit zu generieren.
