Node.js: Microservices

Course details

In this fast-paced era of distributed systems, mastering microservices—not just deploying services, but truly understanding the patterns and principles that drive them— is essential for developers. And in organizations large and small, Node.js is often the platform of choice for building microservices architectures. In this course, Daniel Khan shows you how to use Node.js to create a microservice architecture from scratch and tackles the all-too-common challenge of transforming a monolithic app into a flexible, modular system composed of individual services. Throughout the course, Daniel explores crucial concepts like service discovery, resilience, and decoupling. Check out this course to gain practical knowledge of microservices that you can apply to your day-to-day work immediately.
