Why do we use Node.js in developing our projects?

Node.js is known as a JavaScript-based platform for back-end development

Real life example of using Node.js technology

In what projects does MOST Programming use Node.js?

Node.js is a JavaScript runtime environment (hence its ending in .js, referring to the JavaScript language). This real-time runtime environment includes everything you need to run a program written in JavaScript on the server. It also provides many benefits and solves many problems concepts and necessary skills that motivate us to delve into its options and start programming.

Node.js was created by the original developers of JavaScript. They transformed it from code that could only run in the browser to code that could run on computers or servers as stand-alone applications. Thanks to Node.js you can take JavaScript programming a step further by not only creating interactive websites, but also having the ability to do things that other scripting languages like Python can do.

Back to JavaScript advantages in web-based projects article, Node.js can use all pluses and strengths of modern JavaScript.

The backend of our site is also written in Node.js, which has a positive effect on performance and ease of adding new functionality to the project. It is perfect choice for small-to-medium web-based projects.

As an example of a project, we can use the website of our company, where the backend is written using Node.js. Since we used Nuxt.js as the front-end part of the project and for the side rendering server it uses a server written in Node.js, it was comfortable for us to customize and improve the back-end part of the project. Since node.js allows you to write in JavaScript, it sort of unifies the development team and allows you to spend less resources on creating a project.

Why it is good to use Node.js?

Resistant to mass access and capable of real-time processing

Node.js adopts the "non-blocking I/O" method* and is strong against a large amount of access, and can execute required processing in real-time. Therefore, it can be said that it is suitable for use in applications that operate in real time. Node.js is often used for the development of ticket reservation sites that accept a large number of accesses at once and live chats that do not allow time lag.

Handles a large number of connections at once

The capability of handling a large number of connections is one of the main features of Node js as it can process a large number of connections at the same time. So it does not need to wait for a certain operation to be complete before starting the next one.

Fast small-scale calculations

Server-side JavaScript "Node.js" is characterized by fast small-scale calculations which make the compilation process much quicker and more convenient for use.

Node.js uses Google V8 Engine - an open-source JavaScript execution engine. This allows for very fast operation, and for small calculations, that speed-up calculation process.

Ability to build a lightweight web server

Node.js is designed to be very lightweight, so even if multiple people are using it, it will not slow down. Therefore, a server such as a chat or a ticket reservation web page can be easily constructed using Node.js. without overwhelming a system.

Smooth processing even with different communication speeds

Node.js can handle simultaneous connections and is not heavy, so it is also used for smartphone application development. It is convenient as even if multiple people connect to the smartphone app at the same time, with a difference in communication speed, the process will be smooth and easy for all users without lags and errors.

World-known companies use Node.js

LinkedIn

LinkedIn using Node.js since 2011 to optimize its mobile apps. Now it's run 20 times faster than they used Ruby on Rails.

Netflix

Netflix's UI is built based on Node.js because of the framework modularity. Also, Node.js allows the Netflix website to load two times faster than other streaming platforms.

NASA

NASA created API-driven Node.js enterprise architecture to quick data processing according to to check on spacesuits lifecycle.

Twitter logotype

Twitter

Twitter uses Node.js for mobile app processing optimization even under poor connection conditions - 3G и 2G. It also makes the app lighter, so it takes only 1 to 3% of smartphone memory.

PayPal logotype

PayPal

PayPal chose Node.js to reduce development time as well as speed up performance. The loading time reduced by 35%, which, with 200 million active accounts, significantly affected the system responsiveness.

Uber

Node.js has allowed Uber to process massive amounts of data and numerous user requests in 68 countries much faster, helping the company serve 14 million trips every day.
