The fact that Node.js runs in a single thread does not mean that we cant take advantage of multiple processes and, of course, multiple machines as well. Heres a brief rundown of what each installed package actually helps us with: dotenv : This package loads environmental variables from a .env file into Nodes process.env object. CREATE TABLE IF NOT EXISTS `tutorials` ( id int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT, title varchar(255) NOT NULL, description varchar(255), published BOOLEAN DEFAULT false ) ENGINE=InnoDB DEFAULT Cloud Storage.
