Summary

In this chapter, we embarked on the journey of building a real-life ERP system with NestJS, focusing on design, implementation, and best practices. We covered the following key areas.

We began by understanding the requirements of an ERP system, identifying the core functional and non-functional needs, and defining user roles and permissions to ensure the system meets business and user expectations.

Next, we designed the system architecture, leveraging microservices to achieve scalability and modularity. We explored the high-level architecture, database design, and communication patterns, ensuring a robust and efficient structure for our ERP system.

We then implemented microservices, focusing on creating scalable and maintainable services. We covered service decomposition, communication, and fault tolerance, providing practical code examples and best practices.

We delved into data synchronization and consistency, employing event-driven architecture, synchronous communication...
