javascript - Node.js: SyntaxError: Cannot use import statement outside a module

I am getting this error SyntaxError: Cannot use import statement outside a module when trying to import from another javascript file. This is the first time I'm trying something like this. The main file is main.js and the module file is mod.js.

main.js:

import * as myModule from "mod";
myModule.func();

mod.js:

export function func(){
    console.log("Hello World");
}

How can I fix this? Thanks

In order to use the import syntax (ESModules), you need to set the following to your package.json:

{"type": "module" }

If you are using a version of Node earlier than 13, you need to use the --experimental-modules flag when you run the program

node --experimental-modules program.js

and add {"type": "module" } in package.json

Hope it helps !
