Development with Node

In this course, you’ll start with JavaScript fundamentals, Node.js setup, and core modules. You’ll then build web servers with Express.js, create REST APIs, integrate databases like MongoDB and PostgreSQL, and implement authentication and real-time features with WebSockets.

As you progress, you’ll explore microservices, message queues, and deployment using Docker, Heroku, and AWS. The course also covers testing, debugging, security practices, and concludes with a capstone project to develop a complete backend system.
