Hello in this article, I will share the information about the express module in node.js which is one of the most important and popular frameworks used with Node.js and how we can use it.
Firstly, what is node.js? It is a Javascript Runtime platform started to be developed by Joyent in 2009, where we can write server-side applications with Javascript. It runs on a javascript engine called V8. V8 is vastly coded by C, C ++ and javascript languages developed by Google and which Chrome web browsers also work on. Its sole purpose is to translate javascript code into machine code. It is definitely a very good performance. I created multiple events that run asynchronously and tested them myself. Their response speeds were incredible. Node.js, which runs I / O and network operations non-blocking, is very stingy in time and resources. In other words, if you want to give an example, instant transactions in very high traffic sites can be sent to the client's screen in a very short time and with less resource consumption, using the web socket, as in the same signalR, without querying the user. For example, sending stock exchange information withdrawn from a service to all clients. This will be done as the stock market information changes without querying the user. Real time applications can be done with node.js using web socket technology... Read Continue https://sirnode.com/what-is-express-in-node-js
