Taming reactive node.js: Stream-oriented architecture with NestJS
summary
Shows a concrete migration from a layered REST service to a stream‑oriented CQRS/Event Sourcing design, with a working demo game endpoint where a hero slays dragons, dispatches commands, emits domain events and persists them to an event store. Uses NestJS command/event handlers and an saga using RxJS streams to emit drop‑item and drop‑coins commands. Claims NestJS saw 300% growth in 2018 and the example is demonstrated end‑to‑end and running.
