Mastering Express.js: Build Scalable & Secure Web Applications

This course is designed to provide a comprehensive understanding of Express.js, the powerful web framework for Node.js. You will start with the fundamentals, learning how to set up an Express server and handle routing effectively. As you progress, you will explore middleware, request and response handling, and the integration of templating engines such as EJS, Handlebars, and Pug.

A key focus of this course is working with databases, covering both MongoDB and MySQL, to build dynamic applications. You will gain hands-on experience in implementing authentication and authorization using JWT, OAuth, and bcrypt.js, ensuring secure access to your applications.

The course will also cover building robust RESTful APIs, error handling, and debugging techniques to create reliable and maintainable applications. Additionally, you will learn best practices for performance optimization and security to enhance the stability of your projects.

Finally, you will explore deployment strategies and scaling techniques to ensure your Express.js applications are ready for real-world use. By the end of this course, you will have the skills and confidence to develop high-performance web applications using Express.js.
