What is Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment.

In practical terms, it’s the technology that lets developers run JavaScript code outside the browser. This includes on servers, in APIs, and across distributed systems.

In other words, Node.js is a JavaScript framework that allows developers to test and debug their code in a virtual domain.

The fact that Node.js is open-source and cross-platform means that the framework is accessible in two ways.

By being open-source, skilled developers can edit the Node.js source code to their liking, or otherwise, for the improvement of everyone involved.

Secondly, as a cross-platform software, Node.js is available to virtually any developer, no matter their preferred operating system.

Node.js was developed in 2009 by Ryan Dahl. At that time, Apache HTTP Server handled the things that Node.js does now, but with less efficiency. Specifically, Apache couldn’t tackle concurrent requests. Thus, Node.js was created.

With Node.js, JavaScript developers use server-side scripting to manifest dynamic web pages. Server-side scripting works by running user requests on the server-side, or web server, rather than on the client-side, or web browser.

The advantage of this scripting technique is that clients do not need to deal with slow loading times and high CPU usage. For the same effect, developers can employ static web pages, but website content would be, in turn, far less engaging and interactive.

Server-side scripting empowers developers to dismiss the often-overloaded presence of browser plugins and technology by simply relying solely on the web server.

Today, that same principle powers much of the modern web. Node.js enables fast, scalable architectures for APIs, streaming platforms, and microservices while allowing developers to use one consistent language from the browser to the back-end.

That said, Node.js uses a ‘JavaScript everywhere’ paradigm where the web application development depends on JavaScript for both client-side and server-side programming.

What Are the Advantages of Node.js?

Node.js is used by some of the most popular companies today. With that kind of track record, you have to wonder what makes Node.js so desirable. Below are some advantages of Node.js.

1. Easy to Learn and Work With

Node.js is easy to learn. Though you’ll want professional developers to help you work on the software for your business, accessibility plays a large role in why developers choose to learn Node.js in the first place.

Previous mastery of JavaScript and object-oriented programming is a must. And that requires seasoned developers. But after surpassing that threshold, developers will be relieved to know they can start doing what they came here for – programming.

For teams that already rely on JavaScript for their front-end, Node.js creates a much smaller learning curve.

Developers don’t need to context-switch between multiple languages or frameworks. This shared skill base translates into shorter onboarding times and greater team productivity.

This is an advantage consistently noted by engineering leaders across enterprise case studies.

2. Simple, Unified Technology Stack

Because Node.js is a fan of the ‘JavaScript everywhere’ paradigm, there is no need to switch programming languages between back-end and front-end development.

Most programming projects use tech stacks that require 2-4 different programming languages, frameworks, libraries, and whatever else to account for a variety of development needs, including databases, front-end development, and back-end development.

Node.js allows for only one language to be the primary catalyst for full-stack development. In effect, this leads to fewer files, less code, and overall fewer complications.

This unified approach doesn’t just simplify development.

It reduces maintenance costs and improves code consistency. Many leading companies, including PayPal and LinkedIn, have cited faster development cycles and reduced deployment complexity as major wins after adopting Node.js.

3. Fast and Lightweight Performance

Projects built using Node.js hit the market at a faster rate than otherwise. Node.js is lightweight. As a result, programming in the Node.js environment is faster and easier. Ultimately, this reduces the time spent in development and the overall time-to-market.

Businesses look at faster release times as an advantage. This is because they can get immediate feedback and make meaningful updates.

Such an advantage is also helpful for developing a minimum viable product (MVP) to test Node.js project ideas on the market.

Websites that use Node.js tend to be faster as well.

From a technical standpoint, Node.js’s event-driven, non-blocking I/O model allows it to handle thousands of simultaneous connections with minimal overhead.

This makes it a top choice for real-time systems, like streaming apps or collaborative platforms.

Netflix, for example, reduced startup time by roughly 70% after shifting critical services to Node.js.

4. Built for Scalability

One of the reasons Node.js was made is to offer a more scalable alternative to Apache.

Therefore, scalability is built into the very heart of Node.js. Companies that use Node.js have a need for scalable software in order to plan for business growth.

Node.js can handle several concurrent connections. Another useful feature of Node.js is load balancing, which is the process of distributing tasks competently amongst resources.

This occurs when the load balancer receives incoming requests and sends them off to the server most capable of fulfilling them.

Because Node.js applications are modular by design, they scale horizontally across clusters and microservices with relative ease.

Many large-scale companies, such as Walmart and Uber, leverage this flexibility to handle millions of daily transactions while maintaining high uptime and low latency.

5. Community-Driven

Back on the topic of accessibility, you’ll realize that the most accessible software often has the largest communities. The benefit of a large community is lots of support and feedback.

This same community takes full advantage of the open-source standing of Node.js, building tools to ease the development process for everybody.

Node Package Manager (NPM), the official package ecosystem for Node.js, is the largest and fastest-growing software registry in the world.

With over two million packages available on NPM, developers can integrate prebuilt modules for everything from authentication to analytics. This shortens development time dramatically.

For businesses, that means lower engineering costs and faster innovation cycles.

The strength of the Node.js community also ensures long-term stability and frequent security updates, which is a key trust factor for enterprise adoption.

15 Global Companies That Use Node.js

While Node.js is relatively new compared to other back-end frameworks, it is by no means a novelty. In 2025, it remains one of the top choices for enterprises that demand real-time performance, scalability, and rapid innovation.

Fortune 500 companies continue to favor Node.js for its efficiency, developer productivity, and cross-platform support.

Below, you’ll see how 15 global brands leverage Node.js

Streaming and Media Platforms

1. Netflix

Netflix is a streaming service for television and film serving millions of users worldwide, and likely one of the most familiar to you of the companies using Node.js.

The user interface (UI) of Netflix was built using Node.js.

According to the Netflix team, the modularity of the framework encouraged them to use Node.js. Netflix is also almost two times faster during startup as a consequence.

As already mentioned, they’ve reported startup times reduced by around 70%, improving the customer experience for millions of users.

Netflix engineers also note that Node.js’s lightweight, asynchronous design helps them push frequent updates with minimal downtime.

2. Medium

Medium is an online platform for publishing articles with a large diversity of content. Medium developers build their app servers with Node.js, accompanied by the web server NGINX.

The Medium team enjoys the privilege of being able to share code between the server-side and client-side. They’ve also improved deployment times by roughly 15 minutes per cycle, allowing writers and readers to see platform updates almost instantly.

3. Mozilla

Mozilla Firefox is a popular web browser. Many of its web apps use Node.js because of its memory capacity and for the ease of use involved in being able to keep everything in a single JavaScript repository.

Node.js allows Mozilla developers to quickly prototype, test, and deploy open-source tools.

Its strong package ecosystem supports internal automation, CI pipelines, and web utilities built for the broader developer community.

4. Yahoo

Yahoo was first and foremost a web directory to find news, sports, and finance information. Its role soon extended to email and search engine services as well.

Front-end development is the main use of Node.js for Yahoo, as it is scalable and highly performant.

The Yahoo engineering team uses Node.js to unify UI development and improve server-side rendering (SSR), cutting latency for high-traffic properties like Yahoo News.

Social and Collaboration Platforms

5. LinkedIn

LinkedIn is the social network for professional connections. It is best suited for people looking to make serious career moves who want to get noticed by relevant companies.

In the same vein, companies looking for competitive candidates for open positions use LinkedIn.

LinkedIn switched from Ruby on Rails to Node.js in late 2011. This was mainly because LinkedIn developers wanted to optimize their mobile app, where now everything is written entirely in Node.js.

They were able to drastically cut down on server resources, and the app is said to run 20 times faster than its predecessor. HTML5 was also a big factor in LinkedIn’s mobile app development.

6. Trello

Trello is a collaborative online tool that businesses use to organize projects and ideas using virtual boards.

The typical Trello dashboard can tell its user what is being worked on, who’s working on it, and what step the project is on in the development process.

The server-side of Trello uses Node.js. It is important for Trello and its users to have immediate updates, and Node.js has the capacity to hold many open connections at once.

The Trello team also appreciates the many libraries of Node.js and its functionality for single-page apps.

This choice allows Trello to maintain smooth drag-and-drop functionality and real-time updates across global user sessions.

7. GoDaddy

Businesses use GoDaddy to host websites and register domain names on the Internet.

Their back-end infrastructure is dependent on Node.js. Senior Software Developer Stephen Commisso maintains that this is because of its ability to make quality apps and release new features quickly.

In addition, Node.js is practical for testing, NPM resources, and REST.

Representational State Transfer (REST) defines standards between computer systems and web services, a powerful feature for GoDaddy developers.

Transportation and Real-Time Services

8. Uber

Uber is a pseudo taxi service for people who need to get somewhere fast but are appalled by the inflated prices of a yellow cab.

The people who work for Uber are regular Joes who must go through background checks.

Of the companies that use Node.js, Uber was one of the first to use the framework to its fullest extent by building the bulk of the Uber platform in Node.js.

There are three main reasons why Uber chose Node.js: ease of error-checking, fast processing speeds, and continuous development thanks to the open-source community.

Uber’s dispatch system depends on Node.js to manage millions of simultaneous requests per second, dynamically scaling during peak hours to maintain performance.

9. NASA

As you’re probably aware, NASA – which stands for the National Aeronautics and Space Administration – is a United States government-sponsored department responsible for the research and exploration of space-related matters.

Microservices are a feature of Node.js where developers approach application development by presenting the software as a collection of small services rather than as an autonomous unit.

Using this feature, NASA was able to move its enterprise to the cloud.

By consolidating its complex data systems through Node.js microservices, NASA improved data reliability and reduced time-to-recovery during critical operations.

E-commerce and Financial Platforms

10. PayPal

PayPal is the go-to online platform for making electronic payments through a trustworthy service. PayPal uses Node.js to build user-facing content.

The PayPal software team likes that Node.js empowers developers to build both server-side and client-side applications with JavaScript.

It unifies the developer experience in a way that is helpful to the development process.

11. eBay

E-commerce platforms like eBay let users buy products from individuals and companies via online transactions.

Node.js helps eBay by being able to maintain live connections to servers for nearly 200 million eBay users every day.

The team chose Node.js for its ability to handle high concurrency with minimal overhead, powering real-time updates to auctions, bids, and listings.

12. Groupon

Groupon is another e-commerce platform, except it works with third-party services to provide special discounts and prices. Like LinkedIn, Groupon switched from Ruby on Rails to Node.js in 2015.

Groupon software developers migrated both their mobile and web traffic to the framework.

Higher scalability was their main justification, but this switch resulted in resource reduction for high traffic and faster web pages.

This move also unified Groupon’s global platform under a single stack, allowing regional teams to deploy features independently using shared Node.js modules.

13. Walmart

Walmart is a large American retail company operating several grocery and department stores across the world.

As one of the companies that uses Node.js, Walmart relies on the framework for its UIs and also as an orchestration layer to create application programming interfaces (APIs) for the company’s various apps.

Orchestration layers permit developers to integrate multiple applications or services together. In essence, Walmart app users can use one platform to access several distinct functions.

14. Yandex

Yandex is a Russian multinational corporation specializing in several services, from transportation to search engines. Yandex has numerous API libraries built in Node.js.

APIs communicate procedures between an application and another related application or operating system.

Some of Yandex’s libraries include yandex-translate, yandex-music-api, and maps.

Yandex engineers use Node.js to optimize high-traffic API endpoints, delivering consistent response times even under massive user loads.

15. Citibank

Citibank is a bank that, naturally, offers financial services – both offline and online.

The company uses Node.js for its mobile services with the framework Hapi.js as a willing accomplice.

Hapi.js works with Node.js to provide capable plugins and core functionality for web apps.

This setup allows Citibank to securely handle customer transactions while rapidly deploying new digital banking features in its mobile ecosystem.

When Node.js Isn’t the Right Choice

Even companies that rely on it heavily tend to use it selectively, pairing it with other tools when the situation calls for it. It’s worth knowing where the framework can start to show its limits.

1. CPU-Intensive or Computation-Heavy Workloads

Node.js runs on a single thread, which is great for juggling many light tasks at once. But when you throw it something like complex number crunching, video encoding, or data modeling, that same design can start to slow things down.

In those situations, teams often offload the heavy lifting to other languages like Python for data analysis, Go for concurrency, or Rust for performance-critical services.

In that setup, Node.js acts more like a traffic controller than the workhorse itself, coordinating requests rather than crunching through them.

2. Applications That Need Strict Type Safety

Because JavaScript isn’t strongly typed, large projects can get messy if you’re not careful.

TypeScript helps a lot by adding a type system and catching mistakes early, but it’s not always enough for industries that can’t afford even small errors.

Think of aerospace control systems or enterprise banking software; those teams often stick with languages like Java or C# that guarantee strict type checking before anything ever runs.

Most Node.js projects today use TypeScript by default, which narrows the gap, but doesn’t always erase it.

3. Large, Tightly Coupled Architectures

Node.js tends to shine in microservice environments or event-driven systems where each component does one thing well. But in older, monolithic setups with lots of intertwined code, its asynchronous nature can make things more complicated to manage.

If your business runs a legacy system that wasn’t built for modularity, switching everything over to Node.js might do more harm than good.

4. Limited Multi-Threading (with a Few Workarounds)

For a long time, Node.js didn’t support true multi-threading, which meant it couldn’t efficiently split heavy tasks across multiple CPU cores.

Newer versions have introduced worker threads and cluster modules to help with that, but these features aren’t plug-and-play. They tend to require some architectural planning and a fairly seasoned DevOps team to get right.

How to Choose the Right Node.js Architecture

Node.js can power everything from small APIs to massive distributed systems, but the best setup depends on what you’re actually trying to build and how your team works.

There isn’t one perfect blueprint, though some patterns consistently prove more effective than others.

1. Microservices Architecture

Microservices break an application into small, focused services that talk to each other through APIs. Each one handles a specific task and can be deployed on its own timeline.

Node.js happens to fit this model almost naturally. Its event-driven structure makes it easy to manage lots of independent services without much overhead. It scales horizontally, too, which is handy when traffic spikes unexpectedly.

Uber’s dispatch and routing system is a classic example. It runs on Node.js microservices that expand and contract with real-time demand. Netflix does something similar, using Node.js to handle user interfaces and API gateways for a huge network of smaller services.

It’s not always simple to orchestrate, but for big systems that need to grow and adapt quickly, this approach tends to work very well.

2. Serverless Architecture

In a serverless setup, the cloud manages your servers. You just write small bits of code that run when triggered, like sending an email confirmation or updating analytics after a transaction.

Node.js works nicely here because it starts up fast and doesn’t take up much memory. Most major platforms like AWS Lambda, Google Cloud Functions, and Azure Functions support it natively.

Many startups, especially in fintech and SaaS, use Node.js for serverless functions that handle lightweight jobs like notifications or payment webhooks. It’s cost-efficient and easy to scale, though not ideal for every type of workload.

3. REST or GraphQL API Layer

When your application needs to share data between different systems, Node.js is a strong choice for building APIs. It’s good at managing high traffic and frequent requests without choking the server.

Whether you’re using REST or GraphQL, Node.js’s non-blocking I/O allows for efficient communication and quick responses.

It also plays nicely with NoSQL databases like MongoDB and Redis.

Walmart, for instance, uses Node.js as an orchestration layer to connect various internal systems through APIs. GoDaddy uses it the same way for its hosting and domain services.

For projects that rely on integrations or need to serve multiple front-ends, this architecture is tough to beat.

4. Modular Monoliths

Building a single modular Node.js app can be faster, simpler, and perfectly fine for early-stage products.

The trick is to keep things loosely coupled inside the codebase so that when the time comes, you can split features into separate services without rewriting everything.

Medium famously began with a single Node.js application that evolved into a modular structure as its traffic grew. It’s a good reminder that scaling doesn’t have to happen all at once.

5. Edge and Hybrid Cloud Deployments

For global platforms that need fast response times everywhere, Node.js performs well in edge environments. Because it’s lightweight and container-friendly, it can run close to end users, reducing lag and improving reliability.

You’ll often see this setup in streaming or gaming platforms, where milliseconds matter. Containers, Kubernetes, and Node.js tend to go hand in hand here. It’s a bit more advanced operationally, but the performance gains can be worth it.
