Node.js – Introduction

node.js

The modern web application has actually come a long way over time with the introduction of many standard frameworks equivalent to bootstrap, Angular JS, and so on. All of those frameworks are based mostly on the popular JavaScript framework.

However when it got here to growing server based mostly purposes there was simply type of a void, and that is the place Node.js got here into the image. Node.js can also be based mostly on the JavaScript framework, however it’s used for growing server-based purposes. Whereas going by means of all the tutorial, we are going to look into Node.js intimately and the way we are able to use it to develop server based mostly purposes.

What is Node.js?

Node.js is an open-source, cross-platform runtime environment used for development of server-side internet purposes. Node.js purposes are written in JavaScript and may be run on all kinds of working programs. Node.js relies on an event-driven structure and a non-blocking Enter/Output API that’s designed to optimize an utility’s throughput and scalability for real-time internet purposes.

Over a protracted time frame, the framework accessible for internet growth had been all based mostly on a stateless model. A stateless model is the place the information generated in one session (equivalent to details about consumer settings and occasions that occurred) is not maintained for utilization within the next session with that consumer. A number of work needed to be executed to take care of the session info between requests for a consumer. However with Node.js there’s finally a approach for internet purposes to have a real-time, two-way connections, the place each the client and server can initiate communication, permitting them to change data freely.
