const __dirname = path.resolve();

[Luis-Enrique-Mora]

import path from 'path';
import { fileURLToPath } from 'url';
// data path
const __filename = fileURLToPath( import.meta.url );
const __dirname = path.dirname( __filename );
//* Base directory of the data folder
const templateDir = path.join( __dirname, '/../.data/' );
