Divide and Conquer – Microservices with Node.js
summary
Shows how Node.js can be used for microservices by building an Express HTTP/MVC article service with a model and database, using TypeScript for types, npm/yarn for package management, Jasmine and Frisby for tests, remote logging to a collector, and Docker for container deployment. Presents swapping the transport layer to Seneca (command/pattern patterns over TCP or message queues) for asynchronous communication, uses PM2 to run multiple Node worker processes, and notes the operational costs such as added complexity and the need for clustered databases as traffic grows.
