First, install the latest version of Node.js. It has the latest and greatest features.
Second, add the "type": "module" line in your package.json file.
{
"type": "module"
}
Third, use the --experimental-modules flag when invoking nodejs:
node --experimental-modules app.js
You should be good to go!
An alternative is to avoid adding the “type”: “module” line in your package.json file and instead rename your app.js file to app.mjs.
Note that now the require() syntax will stop working.
