These 11 lines of code, along with the Node.js runtime, are all it takes to create a very basic API or a microservice. Scaling a Node application is not an afterthought, it's built right into the name. In Node, we build simple, small, single-process building blocks (nodes) that can be organized with good networking protocols to have them communicate with each other and scale up to build large distributed programs (microservices?). Small code is actually why Node is named Node. So, here is one of the reasons why you would like to use Node. Node has built-in modules providing rich features through easy-to-use asynchronous APIs.ĭave Bautista improvised Drax’s funniest line in ‘Avengers: Infinity War', “Why is Gomora?”.Node is better described as a wrapper around a VM like V8. ![]() It’s the one who instructs a VM to execute your JS.
