Get Started with Reactive Programming in Spring
Reactive programming allows you to build systems that are resilient to high load. Handling lots of traffic isn’t a problem because the server is non-blocking and doesn’t block client processes to wait for responses. The client cannot directly observe, or synchronize with, the execution that occurs on the server. When an API is struggling to handle requests, it should respond in a sensible way. It shouldn’t fail to work or drop messages in an uncontrolled...

While you can create a server in Node without using a library, it doesn’t give you a lot out of the box and can be quite cumbersome to add functionality.
