Node.js is an open supply, cross-platform runtime surroundings for creating server-side and networking purposes. Node.js purposes are written in JavaScript, and may be run throughout the Node.js runtime on OS X, Microsoft Home windows, and Linux.

Node.js additionally offers a wealthy library of varied JavaScript modules which simplifies the event of internet purposes utilizing Node.js to a terrific extent.

Following are a number of the necessary options that make Node.js the primary alternative of software program architects.

  • Asynchronous and Occasion Pushed − All APIs of Node.js library are asynchronous, that’s, non-blocking. It basically means a Node.js primarily based server by no means waits for an API to return knowledge. The server strikes to the following API after calling it and a notification mechanism of Occasions of Node.js helps the server to get a response from the earlier API name.

  • Very Quick − Being constructed on Google Chrome’s V8 JavaScript Engine, Node.js library may be very quick in code execution.

  • Single Threaded however Extremely Scalable − Node.js makes use of a single threaded mannequin with occasion looping. Occasion mechanism helps the server to reply in a non-blocking means and makes the server extremely scalable versus conventional servers which create restricted threads to deal with requests. Node.js makes use of a single threaded program and the identical program can present service to a a lot bigger variety of requests than conventional servers like Apache HTTP Server.

  • No Buffering − Node.js purposes by no means buffer any knowledge. These purposes merely output the info in chunks.

NodeJS is a rapidy rising internet server know-how, and Node builders are among the many highest paid within the trade. Understanding NodeJS properly will get you a job or enhance your present one by enabling you to construct top quality, strong internet purposes. On this course you’ll achieve a deep understanding of Node, learn the way NodeJS works below the hood, and the way that information helps you keep away from frequent pitfalls and drastically enhance your capability to debug issues.
