What is Node js? Why and How is it used in web development?
Introduction
In the web development field, Node.js has emerged as a powerful tool. It revolutionized the way we build web applications. In this article, let’s understand what exactly is Node.js, and why has it become so crucial in modern web development practices.
Understanding Node.js
Firstly, Node.js is an open-source, cross-platform JavaScript runtime environment. It executes JavaScript code outside a web browser. Initially released in 2009 by Ryan Dahl. Node.js was built on Chrome’s V8 JavaScript engine. It allows developers to run JavaScript code on the server-side. This departure from traditional server-side technologies typically used languages like PHP, Python, or Ruby. It marked as a significant shift in web development paradigms.
Why Node.js?
The advantages of Node.js are:
Node.js developers can use JavaScript for both client-side and server-side development. It enables a seamless transition between frontend and backend code. This reduces context switching and streamlines the development process. It leads to faster iteration and deployment cycles.
With libraries and packages, Node.js boasts a vast ecosystem through Node Package Manager. These packages cover various functionalities, from web frameworks like Express.js and Nest.js. This extensive ecosystem accelerates development by providing pre-built solutions to common problems. It allows developers to focus on building unique features for their applications.
The most significant advantage of Node.js is its asynchronous, non-blocking I/O model. It enables handling click here...
