Description
This course is designed for beginners aiming to master web application and API development using Node.js and Express.js. Express is a minimal, flexible framework that provides essential tools for building robust server-side applications. Over seven detailed lessons, you'll progress from foundational concepts to implementing advanced security features like authentication and authorization. The course emphasizes practical, hands-on learning, ensuring you gain the skills needed to create scalable and secure backend systems.
You'll start with an introduction to Express JS, understanding its role in the Node.js ecosystem and how it simplifies handling HTTP requests and responses. Middleware, a core concept in Express, will be explored in depth, showing how it intercepts requests for tasks such as logging, parsing, and error handling. Routing is covered next, with a focus on using Express Router to organize endpoints modularly, making your codebase maintainable and scalable.
Moving forward, the course introduces the Model-View-Controller (MVC) architecture, a design pattern that separates application logic into models, views, and controllers. Through a practical example, you'll build a CRUD (Create, Read, Update, Delete) REST API, learning to design endpoints, manage data, and implement validation. This section is crucial for understanding how to structure real-world applications.
Security is a major theme in the latter part of the course. You'll implement user password authentication, covering password hashing with bcrypt, session management, and secure storage. Then, JSON Web Tokens (JWT) are introduced for stateless authentication, essential in modern APIs and single-page applications. You'll learn to generate, verify, and refresh tokens, ensuring secure user access.
Finally, authorization is addressed, teaching you how to assign roles and permissions to users and enforce access controls on routes. This ensures that only authorized users can perform specific actions, enhancing application security. Throughout the course, best practices and common pitfalls are highlighted to help you write efficient and error-free code.
By completing this course, you'll be equipped to develop full-featured backend applications with Node.js and Express.js, ready to tackle projects in web development.
