FAQ

What is the difference between .js and .mjs files?

Node.js’s original module system is CommonJs (which uses require and module.exports).
Since Node.js was created, the ECMAScript module system (which uses import and export) has become standard and Node.js has added support for it.
Node.js will treat .cjs files as CommonJS modules and .mjs files as ECMAScript modules. It will treat .js files as whatever the default module system for the project is (which is CommonJS unless package.json says "type": "module",).
