Node.js Fundamentals for Backend Development and Microservices

Node.js enables developers to use JavaScript to build fast, scalable server-side applications, web scrapers, and microservices. This text-based course guides you step by step through backend development concepts, starting with foundational syntax, asynchronous execution, and event-driven architecture. By completing this course, you will understand how to structure backend applications, communicate with external services, and write modern asynchronous code for real-world projects. What you will learn: - Understand essential backend terminology, Node.js architecture, and the event loop - Work with core built-in modules, file systems, and environment variables - Build RESTful APIs using modern asynchronous JavaScript and ES modules - Create microservices and web scrapers to fetch and parse external data - Apply basic authentication, error handling, and security best practices. You will begin with basic definitions and foundational concepts before reading through practical code examples and structural patterns. This course is ideal for beginners and frontend developers transitioning to backend development, with no prior server-side experience required. Start reading today to expand your skills into server-side JavaScript.
