Building JavaScript Microservices with Node.js

Maciej Treder's post guides readers through building basic JavaScript microservices using Node.js, demonstrating how to decompose a monolithic application into a distributed system with independent services. The tutorial outlines the process of creating two microservices—the "heroes" service and the "threats" service—each responsible for specific tasks and communicating via RESTful APIs. The "heroes" service manages a list of heroes with different superpowers, while the "threats" service handles various challenges these heroes can address. The post emphasizes the benefits of microservices, such as modularity, scalability, and independent deployment, allowing for the maintenance and extension of each service without impacting others. Readers are guided through setting up the services, testing them with tools like Postman and curl, and exploring how these services can be expanded in future projects.
