Applications of Node.js

Node.js has the following four major applications:

• Creating REST APIs: We are going to look into this more in subsequent chapters
• Creating real-time services: Because of Node's asynchronous event-driven programming, it is well-suited to reactive real-time services
• Building microservices: Since Node.js has a very lean core, it is best suited to building microservices, since you will only add dependencies that you actually need for the microservices, as opposed to the glut that comes with other frameworks
• Tooling: For example, DevOps automations, and so on
