Fast, simple, easy, powerful, and flexible - these are the words developers use to describe Node.js apps. This technology is internationally popular because it can solve both current and predicted business and user needs.

That is why world-leading companies are using Node.js - and you also have a chance to develop a market-dominating project with its help. In this article, we have collected a list of the most prominent apps powered by Node.js and described what business problems can be solved with its help.

One of the main features of Node.js is its event-driven approach.

  • The growing popularity of interactive applications, social networks, and teamwork solutions led to the growing popularity of Node.js.
  • Here is what you can create with it.
  • The single-page app (SPA) is a lightweight web application that consists of one page only.
  • For example, Gmail or Twitter are SPAs. All the content is downloaded upon initial load, that's why it takes a bit longer than usual.

Prepare for a Career of the Future

However, this enables the app to respond instantly to all user actions - there's no more need to connect to the server. This is how Gmail and Twitter work. Single-page applications adjust to any platform and any screen size. Besides, they can also work offline. SPAs are usually running on JavaScript: Angular, React, or Vue framework on frontend and Node.js on backend.

The essence of real-time applications is clear from the name - this is an application that instantly responds to a user action, for example, chats or games. Node.js is scalable, and it allows handling a large number of real-time users. The main advantage of Node.js is its asynchrony, combined with an event approach. The ability to perform several requests simultaneously makes Node.js a perfect choice for real-time apps.
