6 Real-World Applications of Node.js

Since its initial release in 2009, Node.js has been used by leading technology companies like Microsoft, IBM, Netflix, and PayPal in developing a variety of software products. As a JavaScript runtime environment, Node.js allows front-end web developers to build and execute their website code on a server, thus reducing development time and effort.

A 2018 Node.js User Survey Report reveals that the Node.js framework is used by 4 in every 5 backend and full stack developers. SimilarTech also reveals that companies with high website traffic such as Netflix and eBay are also showing a preference for a Node.js development environment.

So what are the main features of Node.js that makes it popular among web developers? Here are a few:

  • js architecture for both client and server making it ideal for real-time web applications
  • Written using JavaScript
  • Avoids HTTP overload
  • Data streaming functionality for real-time audio and video encoding
  • A dynamic Node Package Manager (or NPM) repository containing open-source modules and development tools
  • Support for both horizontal and vertical scaling

Using Node.js in Real-World Applications

Here are examples of six leading companies who are currently using Node.js in their real-time apps:

PayPal

With over 200 million active users spread globally, Node.js is being successfully used by this payment company for both browser-side and server applications. The company claims that Node.js has helped them create applications at twice the speed and with one-third less coding.

Netflix

As the world’s largest online streaming service, Netflix has been working with Node.js tools to reduce the build time for user interfaces and improve its user customization. The company claims that Node.js has improved the loading time of its application by 70%.

Uber

With its mobile app built using Node.js, Uber has been doubling its user base over the last 2 years, thus speaking volumes of the data processing and scalability aspect of this technology. According to this ride-sharing platform, Node.js has enabled them to process large data volumes in quick time and also deploy their code changes quickly. With Node.js, Uber is capable of processing over 2 million remote procedure calls (or RPC) every second.

Ebay

With a user base of over 170 million customers, this e-commerce retailer chose Node.js environment to handle its huge website traffic. With a live server connection, Ebay apps using Node.js could be built once and deployed on multiple platforms. Starting with one project, Ebay is now transitioning into full-stack development using Node.js.

LinkedIn

With over 450 million users, LinkedIn is the world’s leading business networking platform. With its mobile app backend built on Node.js, LinkedIn has been able to improve its performance and scaling by reducing the number of servers from 15 to just 4 and by doubling its website traffic capacity.

NASA

Node.js was used for keeping the NASA astronauts safe in outer space. By designing an enterprise-wide architecture using Node.js, NASA has been successful in building a single database and reducing access time by over 300%.
