Ladies and gentlemen, that is what Node.js is.
Node.js can be installed on a server (just like Python) and your code can be executed on it, giving the result of execution to users. On it, you can make separate applications using additional frameworks.
The framework is used by front-end developers, back-end developers, and others. It allows you to write a program for different operating systems: Linux, OS X, and Windows can be used to create an API. Node.js is also used to develop cross-platform applications: for example, a task list that should work on different platforms, synchronize data in real-time and send it to a mobile device. Node.js is used to create services with a constant exchange of information with the user: social networks, online games, chats, project collaboration systems, online text editors, etc.
How does a regular web server work?
There used to be this problem:
How the server works on Node.js
In addition to web Node applications, this language is used to create any services where a constant exchange of information with the user is needed:
Recently, the use of Node.js for the “Internet of Things” – smart kettles, scales and other household appliances – is gaining great popularity. This is where Node.js helps manage these fixtures and make servers that can process many requests at the same time.
According to Stack Overflow, Node.js is the absolute leader in the world of technology, occupying 50.4% of the market. Why did it become so popular?
According to the latest Node.js report, this technology has a significant impact on businesses: it provides a 68% increase in developer productivity, a 48% increase in application performance, and a 13% increase in customer experience.
Given the long list of Node.js benefits above, it’s easy to believe that some of the biggest companies using Node.js apps include NASA, Netflix, and eBay. Below, we’ll overview which companies have already switched to Node.js web apps and how it turned out for them.
Netflix is the largest streaming content and video provider with 93 million users worldwide. Its path to modern success began in 2015 when Java as a back-end technology could no longer keep up with such a rapidly growing user base. The back-end development was not keeping up with the front-end, which increased load times. It was impossible to implement a custom UI design, which reduced the quality of the customer experience. In addition, it took too long to build Java, so the development and deployment processes were inefficiently slow.

Trello is a project management tool used in many industries and countries. A platform like this requires instant, real-time updates without delay, which is why Trello has become one of the companies using a backend with Node.js. Trello needs to juggle multiple real-time server connections to keep updates flowing smoothly and on time.

Another company using a web app with Node.js is LinkedIn, the largest social platform for business and employment. Its popularity continues to grow, and the user base is more than 467 million from more than 200 countries. After switching from Ruby on Rails to Node.js, the company created an application that runs ten times faster than the old version. The decision was made due to the synchronization of the Ruby application, which led to an increase in load time, especially when the amount of traffic increased.

Another example of a Node.js application is eBay. With 183 million users, eBay is the largest marketplace providing C2C and B2C online sales services. In the past, the eBay application ran in Java, resulting in long loading times and poor performance. Since eBay is a platform with a huge amount of traffic, it needed a technology that would speed up development so that it could keep up with changes in the front end.
Benefits for eBay:
Groupon is the largest marketplace for coupons, discounts, and great deals. It has a base of more than 40 million users. When Groupon reached 200 million downloads in 2019, it ran into scalability issues. It was then that the company turned its attention to Node.js and conducted the world’s largest deployment of a product on Node.js.
Benefits for Groupon:
Medium is a well-known online publishing platform with 85 million users using Node.js. After hitting 7.5 million posts in 2016, the Medium team felt the need to manage big data without overburdening their servers. In addition, the company had to meet the ever-increasing requirements of text editors for publishing posts.
Benefits for Medium:
