Node.js Takes Over: 7 Popular Types of Node.js Apps You Can Build in 2023

Node.js powers scalable, real-time apps for tech giants like LinkedIn and Netflix. Explore 10 popular use cases. Learn more about Node.js for modern web apps.

Node.js is a versatile platform that offers developers a fast and efficient way to build scalable, real-time applications. Many leading tech companies, including LinkedIn, Netflix, Uber, PayPal, and Mozilla, have recognized the benefits of Node.js and are using it to build innovative applications that meet their business needs. In this blog, we will explore 10 popular types of Node.js applications and why this platform is a top choice for building modern web applications.

Why Node.js is a Developer's Best Friend: Exploring the Advantages

Node.js is a popular choice among developers for building event-driven applications and servers, thanks to its single-threaded and real-time push architectures. Additionally, it's ideal for developing traditional web application back-ends and APIs. Let's explore why Node.js is a great choice for building various types of applications.


One of the key advantages of Node.js is that it allows you to build applications that can scale with your business. By using microservice architecture and containerization, you can achieve scalability and flexibility with almost zero effort.


Another advantage of Node.js is its high-performance benefits, thanks to its use of Chrome's V8 Engine. Companies like Uber recognized this early on and adopted Node.js in its early version in 2009.


The microservice nature of Node.js is a huge advantage for maintainability. Splitting your codebase into small, modular chunks makes it much easier to maintain and update than a single bloated codebase.


Node.js offers several usability benefits that can make the web application development process faster and more efficient. These include its microservice architecture, which allows you to use one programming language in both front-end and back-end, and the availability of millions of libraries through NPM to serve your exact development needs.

Top Companies Building Node.js Apps

With its numerous benefits, it's no surprise that many top tech companies have adopted Node.js for their applications. Some of the most notable companies include:


Netflix Node. js App

Netflix is one of the world's leading subscription-based streaming services, serving millions of users worldwide.

Netflix started using Node.js in 2015 for its user interface on all devices, including mobile, web, and smart TVs. The company chose Node.js because it can handle a large volume of concurrent connections and efficiently serve millions of users. The migration to Node.js allowed Netflix to improve its performance and scalability, reducing response time by up to 70%. Node.js also allowed the company to implement real-time data updates, ensuring a seamless user experience for its millions of subscribers.


Uber Node.js app

Uber, the ride-sharing giant, has been using Node.js since its early versions. They adopted it because of its performance benefits, including the ability to handle a high volume of requests in real-time. Uber uses Node.js for its back-end systems, including its API and dispatch services, and has credited it with reducing development time and improving scalability. Additionally, the microservice nature of Node.js has helped Uber to split its codebase into small, manageable chunks, making it easier to maintain and develop.


LinkedIn is a social media platform for professionals seeking career connections and job opportunities. The company started using Node.js initially for their mobile app and eventually migrated their entire codebase to it. This transition resulted in a 20 times faster app speed than their previous Ruby on Rails iteration. This is a testament to Node.js's efficiency and scalability for large-scale applications.


PayPal is an online payment system that allows users to send and receive money globally. It's used by millions of people and businesses worldwide for online transactions. PayPal started using Node.js in 2013 to improve its performance and scalability. They experienced a 35% decrease in response time and a 50% reduction in the number of servers required to handle the same traffic volume. This helped them to save money and increase efficiency. They also used Node.js to build their internal tooling system, making it easier for developers to collaborate on projects and improving the speed and quality of their development process. Overall, Node.js has helped PayPal to become more competitive in the online payments market.

7 Popular Types of Node.js Apps

Node.js is a versatile tool that can be used for a wide range of applications. Here are ten popular types of Node.js apps:

Real-time chat applications

Real-time collaboration has become a crucial aspect of modern business and work processes. This is where Node.js comes in as a powerful engine for creating collaborative tools. Its asynchronous and event-driven architecture provides the foundation for building and scaling collaborative applications.

Trello node.js app

Many popular collaborative tools big tech companies use, such as Trello for project management and Slack for group chats and remote team communications, are built on Node.js. This is because Node.js is suitable for creating real-time collaborative tools ranging from coworking apps to project management, video and audio conferencing, and collaborative document editing. Its ability to handle multiple connections and events in real-time makes it a top choice for developing collaborative applications.

Data streaming applications

Node.js is an excellent choice for building data streaming applications, including media streaming and real-time data processing. Its non-blocking I/O and event-driven architecture make it ideal for handling large volumes of data without affecting the application's performance.Node.js is often used with other technologies like WebSockets and MQTT to build real-time data streaming applications. These applications can be found in various industries, including finance, healthcare, and transportation. Overall, Node.js is a reliable and scalable technology for building data streaming applications that require real-time processing and high performance.

Video conferencing applications

Video conferencing has become a vital tool in modern business communication, especially with the rise of remote work. Node.js provides an ideal platform for building video conferencing applications due to its real-time event-driven architecture, enabling seamless data transfer with minimal latency.

Leading video conferencing apps like Zoom and Microsoft Teams use Node.js as the backbone for their real-time communication features. Node.js makes it possible to build scalable, reliable, and high-performing video conferencing applications that can handle many concurrent connections.With Node.js, developers can quickly create video conferencing apps that support high-quality audio and video, screen sharing, file sharing, and other critical features for modern collaboration.
