Summary
This chapter offered a comprehensive guide to building robust microservices with NestJS, transitioning from monolithic to scalable architectures. We started by defining and implementing microservices, highlighting the strengths of NestJS’s modular design that facilitates inter-service communication and data management. We then created a mono repo structure that hosts multiple services, enabling them to harness the full potential of NestJS’s microservices architecture.
Moving on, we focused on inter-service communication, demonstrating how services can interact through both synchronous HTTP requests and asynchronous event-driven patterns. Using practical examples such as an order management system, we learned to set up event handlers, define DTOs, and implement event patterns for seamless interaction between services.
Furthermore, we explored best practices for building microservices with NestJS, emphasizing modularization, environment-specific configuration...
