This document discusses how Node.js can help address challenges with microservices architectures. It outlines common problems like logging, configuration, health checks, and common logic that must be addressed across microservices. Node.js solutions like common logging packages, tracing middleware, and process managers like PM2 are presented as ways to solve these problems by creating reusable components and standardizing infrastructure across services. Examples of implementing common logging and tracing are provided to illustrate how Node.js can help build more maintainable microservices applications.
