A Glimpse into the Future- Popular Websites Built with NodeJS

Node.js is a powerful JavaScript runtime environment that allows developers to create fast and efficient server-side applications. It is an ideal choice for building robust web applications.

More importantly, leveraging the lightweight V8 engine, Node.js can easily scale up or down and capably deliver reliable performance to its users, making every person’s web app scalable and capable of handling heavy loads. In addition, through its huge library of modules, the best NodeJS frameworks facilitate easy access to different features such as file system manipulation, networking libraries, and templating engines.

Hire dedicated Nodejs developer in order to build a robust application that can handle heavy loads. With such an asynchronous event-driven architecture from Node.js installed on a web app, developers can effortlessly build scalable real-time applications with higher throughput rates when compared to other programming languages like Java or C++.

On the same note, Node.js remains mainly applicable to creating dynamic web apps, contrary to simultaneously providing a very enjoyable development experience.

Why websites are important for businesses today despite mobile apps?

Businesses use web pages to showcase their products and services to today’s population. They offer a means for customers to get information about the types of products offered by a company, direct contact with that company, reviews from consumers who have purchased a product or service, or can even make purchases over the internet.

In addition to providing more information than many mobile apps provide nowadays, websites greatly enhance their ability to reach potential customers: they can be accessed through any computing device/system, including smartphones and tablet computers running different operating systems like Android and iOS.

Besides offering these devices’ native features, almost every website offers strategies (like analytics and tracking) that are only available in a few mobile apps today. In this sense, websites continue to be an important resource today for businesses seeking an effective way to promote their products and services online.

Hiring a web development company for your website has numerous benefits. Your website will be optimized to appear higher on Google’s first page. Analytics, tracking, and mobile app-only tactics will also be available.

We all know that there are many benefits of NodeJS for startups. These include its ability to handle high-traffic websites and its use by popular companies.Many companies use NodeJS as a part of their system. Let’s take a look at some of the most famous Node JS Apps:


Netflix, the world’s largest streaming service with over 232.5 million active users, transitioned to Node.js for faster interface loading to enhance user experience. Through Node.js, Netflix was able to address the challenges of a monolithic application design and improve scalability.

As a result, the startup time was reduced significantly due to the transition to Node.js’ asynchronous codebase. This in turn allowed the application to be more efficient and let developers communicate easier from the frontend to the backend. Since transitioning to Node.js, Netflix has continued expanding its use of this technology across different layers of its technology stack.


Aeronautics pioneer NASA turned to Node.js for database access optimization related to EVA Spacesuits. With data scattered all around the location but with slow access times, NASA needed a quick solution regarding consolidating database awareness and making their databases appropriate for research usage.

In connection with implementing Node.js, NASA delivered about 300% enhancement in database access time, allowing scientists to gain the required database gains within the shortest time possible. Due to the microservices architecture delivery by Node.js simultaneously, they could also properly migrate the legacy 30-year databases into the cloud, thus enhancing data availability at any place or venue.


Trello, a popular project management tool based on Javascript, uses Node.js to cater to instant updates and real-time connectivity. Trello’s frontend code required a server that matched its Javascript structure but could simultaneously talk to different frontend components easily.

Through such development as that provided by Node.js, Trello was able to experience quick prototyping and lightweight single-page application creation apart from maintaining zero latency server interactions owing to it. Node.js enabled PayPal to develop new projects quicker, better, and with unexpected results. The fact of enhancing their way of working is nothing short of astonishing.


This is one of the popular websites built with NodeJS. PayPal mounted to undergo development and performance enhancements involved in its JAVA-based application. PayPal encountered issues concerning synchronization and efficiency where they had separated between backend development designed in Java and frontend development faced therein.

PayPal has developed an approach leveraging Node.js whereby unexpected results have been experienced beyond accomplished expansion.

As well as reduced developers’ work time, size of codes, and handling/speed of page loading.Node.js enables PayPal to handle more requests per second, thus improving overall application performance.


LinkedIn is considered the largest professional network in the world, with over 930 million users. The company turned to Node.js to improve the performance of its app because its Ruby App used synchronous code and heavily loaded the page.

Resource usage improved, resulting from fewer machines necessary for hosting the application. Using Node.js made client-server interactions more manageable and simplified code structure. The transition to Node.js allowed LinkedIn to build a more modular, reusable, and efficient codebase.


This is also one of the companies using Node JS backend. Walmart became one of the first leading supermarket giants trying to reduce e-commerce website costs by adopting Node.js optimization. The retailer hosts almost 80 million users who browse through the Website or download mobile applications to access their products. Walmart realized it needed a robust and scalable system to handle the load.

By using monolithic Java web applications and focusing on mobile eCommerce requirements, Walmart’s performance increased, but it was still challenging to work with distributed-yet-close teams. Most of the time, Walmart had to rely on manual development which created delays during updates and maintenance of the systems. Web development using Node JS helped automate the process.


Node.js was the backend solution powering Uber, a ride-hailing platform processing millions of concurrent requests. With an acrid architecture based on distributed principles and a host of modules linked to each other via connections, Uber needed a backend that could manage a large number of clicks and would effectively integrate route services.

Node.js proved appropriate, allowing for a reliable and self-healing environment for web and mobile applications in its back end. It also imparted a useful asynchronous and event-driven characteristic to Node.js, allowing trip execution and API connectivity efficiency and reliability.


Due to its core focus on social networking and popularity amongst Internet users, Twitter turned to Node.js to fine-tune its differentiating factors encircling mobile friendliness and patchy ad loadings.

With about one-fifth of its user base accessing Twitter at any time via their mobiles, Twitter required Node.js to boost click rates and optimize the user experience serving ads on the site. Coded in JavaScript, Node.js made possible efficient developers and deployments fostering iterations speeding up the development process, and arresting throttles.


Yahoo, a platform heavy in content with many services, used Node.js to reduce resource utilization and improve website performance. The Yahoo-powered website required a reliable server-side processor to handle numerous requests through minimum latency.

The usage of Node.js offered performance improvements to the usage of Yahoo’s application across its products. It provided faster loading speed support and facilitated the creation of new modules for third-party applications. Additionally, it allowed Yahoo to shift its backend and frontend code from a more costly platform to a more JavaScript-friendly one, thereby increasing the development speed and delivering features quickly.
