How To Implement Node.js Microservices Architecture
1 min read
Summary
Node.js microservices architecture involves breaking down large applications into smaller services that are developed, deployed and scaled separately, and communicate via defined APIs
Node.js runtime, built on Chrome’s V8 engine, offers an event-driven, non-blocking I/O model that is efficient for building microservices to handle multiple concurrent requests
Adopting microservices in Node.js enables an app to be broken down into distinct services developed separately, and provides tactical and strategic benefits such as scalability, fault isolation and faster development and deployment
Guide covers practical steps for implementing a microservice architecture in Node.js, including defining service boundaries, choosing a communication protocol, implementing service discovery and an API gateway, using relevant Node.js frameworks and tools, implementing communication between services, enabling logging and monitoring, managing data persistence and containerisation, and automating deployment.
Practical tips cover starting small, using consistent API standards, automating testing, managing dependencies, securing services, and monitoring service health.
