[javascript] SyntaxError: Cannot use import statement outside a module

According to the official doc (https://nodejs.org/api/esm.html#esm_code_import_code_statements):

import statements are permitted only in ES modules. For similar functionality in CommonJS, see import().

To make Node treat your file as a ES module you need to (https://nodejs.org/api/esm.html#esm_enabling):

  • add "type": "module" to package.json
  • add "--experimental-modules" flag to the node call
