Companies like Netflix, PayPal, Intel, eBay, and Uber… What do these people have in common with their names? Of course, they all provide a very well-liked service or product. All of these companies operate on a worldwide scale, provide services to millions of customers, and develop highly scalable network applications. Each one of them chose Node.js as their development platform.
It’s hardly surprising that Node.js has gained popularity in the business world, as the framework has several advantageous features. But for the time being, allow me to demonstrate the remarkable achievements of some large corporations utilizing Node.js. With the help of Node.js, 5 apps were developed for various sectors and provided several significant advances.
Let’s get started.
- Netflix
Is there anyone who hasn’t heard of Netflix by now? Netflix burst into our lives and swiftly surpassed all other subscription services, with over 200 million subscribers in 190 countries receiving their favorite movies and television shows. As a single monolithic program, it had 40-minute startup times and required writing the same lines of code twice, once for the server and once for the client.
The world’s largest streaming service opted for Node.js due to the relative simplicity of the framework, the fact that it avoided the need to write code twice, and its exceptional speed. The team ultimately decided to switch to Node.js from a monolithic JVM-based system due to issues with vertical scalability.
Thus, the Netflix team could convert the site to a single-page application, cutting load times to under a minute. Thanks to Node.js, Netflix’s single-page design is user-friendly and has a lightning-fast load time.
LinkedIn is an impressive success story as a business-oriented social network with over 830 million users. They joined the Node camp when the framework was just a year old but was gaining momentum quickly.
After switching to Node.js for the app’s backend, they saw significant speed improvements (up to 20 times quicker) and integration (between the app’s front and back ends).
- PayPal
Over 400 million people use PayPal, a payment system that began as a Node.js development platform before it switched all its Web applications from Java to Javascript and Node.js.
Using the same language on the server and client sides improved internal communication and overall product knowledge, which was a major element in the decision-making process.
When it comes to online payments, every second counts, which is why PayPal’s developers were able to reduce response time by 35%, which resulted in websites being provided 200 milliseconds quicker while also writing 33% fewer lines of code and using 40% fewer files.
- eBay
While the American e-commerce behemoth eBay would seem like it would only be interested in tried-and-true technology, it picked the then-emerging Node.js because of the benefits it promised and the developer team’s willingness to try new things.
Additionally, the major objective was to coordinate many eBay-specific services showing data on the page, e.g., performing I/O-bound tasks, so that the application could remain in “real-time” as much of the time as feasible.
Since Node.js proved so successful on the backend, the team behind the project decided to create a Node. js-based frontend stack that could take advantage of the majority of the code already written.
- Uber
This ride-sharing network has expanded rapidly over the past few years, with operations in more than 70 countries across six continents and the processing of millions of rides every day.
Node.js was deployed to create a vast system for matching drivers and riders. This was done because Node.js is well-suited to distributed systems that make many networks queries to swiftly analyze enormous volumes of data.
According to their blog, “xxxNode.js offers us the flexibility to manage enormous volumes of concurrent connections,” making it the ideal choice to power the original core trip execution engine.
One such factor was the huge number of web developers that back Node.js.
Similarly, the business describes an API Gateway, one of the largest NodeJS apps at the time, which communicated with over 2,200 micro-services:
- Peaking at 800,000 requests per second
- Nearly a million lines of code are concentrated in the area of core user flows.
- Among other stunning statistics
Even though they were “one of the first two organizations to deploy Node.js in production,” the company nevertheless takes great pride in being an early adopter of the language.
