This code imports a module and a specific function from it, using Node.js's require function and the import method of the imported module. It then uses the imported function to save credentials, passing in an object with 'host', 'password', and 'username' properties, with the password masked for security.

Cell 2

var importer = require('../Core');
var saveCredentials = importer.import("add encrypted passwords.json");

saveCredentials({
    host: 'linkedin.com',
    password: '********',
    username: 'megamindbrian@gmail.com'
});

// Import the core module
import { Core } from '../Core';

// Create an instance of the Core class
const core = new Core();

/**
 * Save encrypted credentials to a JSON file.
 *
 * @param {object} credentials - Credentials object
 * @param {string} credentials.host - Host URL
 * @param {string} credentials.password - Encrypted password
 * @param {string} credentials.username - Username
 */
export function saveCredentials(credentials) {
  // Use the add method from the Core instance to save the credentials
  core.add('add encrypted passwords.json', credentials);
}
