Integrating Microservices in Node.js Applications

Integrating microservices in Node.js involves establishing communication and coordination between different services to create a cohesive and functioning system.

We’ll start this chapter by integrating microservices into Node.js applications. When integrating microservices into Node.js, consider the specific requirements of your system, the communication patterns that best suit your needs, and the tools and libraries available in the Node.js ecosystem.

By the end of this chapter, you will be able to integrate microservices into your Node.js applications and build a robust and scalable architecture that can handle complex business requirements.

In this chapter, we’re going to cover the following main topics:

• Synchronous HTTP/REST communication and asynchronous messaging
• Event-driven architecture (EDA) and API gateways
• Service mesh and caching
• Distributed tracing and database integration
