Building and structuring a Node.js MVC application

The tutorial provides a comprehensive guide to building a Node.js web application using the Model-View-Controller (MVC) architectural pattern, with a focus on creating a well-structured sample app that includes a login and registration system. It emphasizes the separation of concerns inherent in the MVC pattern, dividing the application into models, views, and controllers to improve maintainability. The process involves setting up a Node.js environment with Express for HTTP endpoints, Pug for server-side HTML rendering, Sequelize.js as an ORM for database interaction, and Passport.js for user authentication. The guide details the creation of user models, views for registration and login, and controllers for handling functionality, illustrating how to protect routes and manage sessions. Additionally, it outlines how to implement user registration, authentication, and logout features, while employing bcrypt.js for password hashing to enhance security. The tutorial also highlights the use of SQLite as the database engine and demonstrates how to organize code for scalability, making it a useful reference for developing large-scale applications.
