Warn when package.json contains an invalid "type" value

What is the problem this feature will solve?

Valid (meaningful) values are:

• commonjs
• module

I had set CommonJS, and it behaves the same as if type was unset, which is so close to the actual commonjs behavior, that I thought I had set it correctly. But I kept having cases resulting in the MODULE_TYPELESS_PACKAGE_JSON warning, instead of failing hard.

Note that while tsconfig.js ignores case, the canonical version is CommonJS, so I never considered that I was using incorrect case.

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

Raise warning/error if "type" is set, but value is none of commonjs or module.

What alternatives have you considered?

Inizia tracciando dove Node.js gestisce il campo type di package.json ed emette l’avviso MODULE_TYPELESS_PACKAGE_JSON; l’issue non indica alcun file sorgente né alcun test, quindi mappa prima quel percorso e la relativa copertura esistente. Definisci e testa il comportamento scelto di avviso o errore per i valori diversi da commonjs e module, preservando questi valori canonici.
