JavaScript and Node.js Fundamentals for Microservices

Modern backend systems rely heavily on fast, decoupled services that handle specific application tasks efficiently. This course provides a clear guide to building backend microservices with JavaScript and Node.js, perfect for developers looking to expand their service architecture toolkit. You will learn to write modular server-side code, connect services via HTTP endpoints, and handle asynchronous data flows. Through structured text-based explanations and readable code snippets, you will build a solid understanding of how independent services communicate. What you'll learn: - Understand foundational JavaScript terminology, data structures, and modern module syntax - Master asynchronous programming using promises and async/await in Node.js - Design simple RESTful APIs and handle JSON payload parsing - Build decoupled microservices that manage isolated backend responsibilities - Implement basic error handling, structured logging, and environment variables - Apply best practices for project setup and package management using npm. The course begins with core syntax, runtime concepts, and fundamental definitions before moving into API design and service structure. You will follow step-by-step written explanations that guide you from initial setups to functioning backend components. This course is designed for beginners and developers familiar with other languages who want a straightforward introduction to Node.js microservices without unnecessary complexity.
