NodeJS Microservice COMPLETE Production Level Course - Node.js Microservices in Practice: Split a Monolith E-Commerce App Step-by-Step

🚀 Node.js Architecture Tutorial: Monolith to Microservices Step-by-Step In this step-by-step Node.js architecture tutorial, we take a real-world monolithic e-commerce app and break it into fully working microservices. You’ll see exactly how to move from “everything in one codebase” to separate Customer, Product, and Shopping services — each with its own database, logic, and endpoints. We’ll start by revisiting the existing monolith, walking through routes, controllers, services, and repositories. Then we’ll compare monolithic vs microservices architecture, talk about API Gateway, loose coupling, and why separate databases matter. After that, we’ll spin up three Node.js microservices, wire them behind a simple gateway proxy, and reuse your existing clean architecture (API → Service → Repository) inside each service. This video is perfect for beginners and backend developers who understand Node.js but struggle to visualize how microservices actually work in a real project. By the end, you’ll know how to design boundaries, split features, and keep your code testable and maintainable as your system grows.
