Support clearing Node.js cache for package.json

What is the problem this feature will solve?

When a long-running Node.js process is active and a package.json file is modified (for example, by adding "type": "module"), Node.js does not detect this change. It continues treating the package as CommonJS, which results in an error like Unexpected token 'export' when attempting to use ES modules.

This is crucial for us at bit, where we run a background process called “bit server” that manages the local development workspace. Among its tasks is creating new web components, which initially have a package.json without "type": "module". If the component is later determined to be ESM, the package.json is updated accordingly. (Explaining why this can’t be handled differently is beyond the scope of this feature request).

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

I propose adding an API that allows clearing the cached information related to the package.json of a specific module (or optionally clearing the cache for all modules). Either option would solve the issue.

What alternatives have you considered?

Restarting the Node.js process, but this results in a poor user experience.

In der Issue wird keine Datei und kein Test genannt. Beginne damit nachzuverfolgen, wo Node.js die Modulmetadaten von package.json zwischenspeichert, und definiere dann eine API zum Löschen des Caches eines einzelnen Moduls und optional aller Module; abgeschlossen ist die Aufgabe, wenn Änderungen des Pakettyps ohne Neustart des Prozesses erkannt werden.
