How to copy a file in node.js?

Question

I'm learning Node.js and using the Hyper Terminal and Visual Studio Code. I want to copy a file through Hyper Terminal and notice that const fs = require("fs"); doesn't work in CommonJS. So I try to use the import like it says in Node.js docs. This is the code:

import * as fs from 'fs';

fs.copyFile("file1.txt", "file2.txt", messageFunction);

function messageFunction() {
console.log("file 1 was copied");
}

This is what it shows on the Hyper Terminal:

Catarina@DESKTOP-3FEBJ01 MINGW64 ~/Desktop/HTML.CSS.JAVASCRIPT/intro-to-node
$ node index.js
file 1 was copied

The problem is that does not create a new file, it simply shows the console.log. I also create a package.json and add "type" : "module".

Thank you!

So, after 2 days I found the solution... I wrote on the paste file1.text instead of file1.txt.

But I learnt that if you use import with the callback function you have to change the package.json to "type" : "module", and if you use the const with the return you need to also change the package.json to "type": "commonjs".

Hope it helps other people! Thank you :)
