10 API Communication and Data Contracts in Microservices

When working with microservices architecture and Node.js, API communication and data contracts are some of the pillars of building a successful application.

We’ll start this chapter by understanding better how to work with APIs and data contracts in microservices with Node.js. Communicating between microservices through APIs involves establishing a clear contract for data exchange and defining the interface through which services interact with each other. By following these practices, you can establish effective communication between your microservices using APIs. This enables decoupling, scalability, and flexibility in your microservices architecture, allowing individual services to evolve ...
