Microservices

Dividing the app with respect to a functionality unit is called a microservice. Each microservice becomes the self contained unit of deployment. Node.js is based on the common JS modules pattern which provides modularity in structure of an application. Such a pattern is used to create the microservices. With the increase of functionality, the number of microservices increases. To manage those services, the Node.js ecosystem provides powerful libraries like pm2. Therefore, it enables the elements of an application to be updated and scaled separately.
