What is Node.js, Where, When & How to Use It In 2023


Did you know that eBay and AliExpress also use Node.js as their main environment for running JS? In 2018, there were about 23 million developers around the world. Get started and discover why Node.js is a good choice for your next project. We’ve talked about a few interesting examples of how Node.js is used. Use this information to help you plan for the future.

How Node.js Works:

It’s easy to make scalable web apps with Node.js, an open-source alternative to Google Chrome’s Javascript runtime environment. This setting is based on JavaScript version 8, which Google Chrome uses. It is perfect for real-time applications that use a lot of data and run on shared devices because I/O is driven by events and doesn’t block.

The Good Things About Node.js


Node.js apps are easy to scale both horizontally and vertically. Horizontal scaling lets you add new nodes faster, while vertical scaling lets you add more resources to the nodes you already have.

Worked very well:

The V8 JS engine works with byte-by-byte JavaScript perfectly. This makes the framework use less energy overall and gives it a speed boost.

Good support from the public:

The people who started the Node.js Foundation in 2015 came from well-known companies like IBM, Microsoft, Fidelity, and SAP.

The Good Things About Nodejs

Speeds things up:

With Node.js, developers can make web apps much faster using its lightweight and flexible tools. The npm repository has many modules, libraries, and solutions that can make high-quality web apps quickly and easily.

Independence for programmers:

Node.js allows programmers to make programs that can run on different platforms. Node.js can build cross-platform web apps with frameworks like Electron and NW.js. This is because it works with desktop, mobile, and web development for Mac, Windows, and Linux.

Unique computer language:

Node.js gives you a mix of JavaScript languages for the front and back end that are very similar. You might not think it’s easy or flexible, but it is. It makes the whole process of making web applications for businesses better and more efficient.

Contributions to the full stack and the MEAN stack:

JavaScript is still the most popular programming language, but Node.js has proven useful and is now an important part of a strong tech stack. Node.js adds a lot of value to a technology stack when it is used on its own, thanks to features like its JSON module library.

Just what does Node.js do?

Social media and networking’s most important building blocks

Many well-known websites, like LinkedIn and Medium, are rewritten with the help of Node.js. Any social networking site needs a certain set of “nodes” as its base. The V8 engine in Node.js makes routing very fast and supports safe authentication. Scalability is one of the most important things that improve a social media platform.

Make a website that can be used as a single app.

Developers can use Node.js to make single-page apps that look like desktop programs. Node.js is the best choice for developing SPAs because its asynchronous data flow on the backend is so good.

Node.js gives you access to unique and advanced features that can be used to make chatbots and other real-time apps. Chatbots are most wanted for their ability to handle multiple users, large amounts of data, and a lot of traffic from many devices. Node.js is the best language for building chat and chatbot apps because it works on all platforms and supports all relevant paradigms. Node.js’s small size makes it easier to use server-side event loops and push notifications, which are common in IM and real-time programs.

The flow of data

Netflix, which has more than 120 million customers and more than 100 million streaming hours per month, was quick to adopt Node.js. Node.js has a clear advantage here because of how quickly it can process files and how light it is when encoding and uploading. There are now a lot of apps and websites about fashion that use this trend to their advantage by streaming high-definition videos.

Developing software for the Internet of Things

IoT’s popularity has risen like a rocket in the last ten years. Since then, Node.js has become a popular option for companies building infrastructure for public and private IoT solutions. Simply put, Node.js’s best feature is that it can handle thousands of events from billions of devices on its network simultaneously with hundreds of requests.

Is there ever a time when Node.js shouldn’t be used?

We’ve talked about some of Node.js’s most obvious benefits, but there are a few times when you should refrain from using it. When you look for the best tool for the job, you might feel like there are too many options. Every technology has pros and cons, but the real question is whether or not you will use it to make the following applications.

A server-based web application that uses a relational database

Node.js and express.js can also be used to make plain-Jane server-side web apps. If these web apps did a lot of CPU-intensive calculations, Node.js might not be able to respond as quickly. Since Node.js’s Relational DB tool is still in its early stages, it’s best to look into other ways to deal with relational data.

Is there ever a time when Nodejs shouldn't be used

The server has a lot of power to process things.

Due to its event-driven and non-blocking I/O node models, Node.js may not be the best choice for server-based tasks requiring much processing power. It stops new requests from coming in while those threads are busy adding up numbers.

CPU intensive computations

The simple, node-based approach has worked well and set several performance records. Node.js may not be right for your web-based software because it only supports a few threads. It will always get stuck if you ask the server to do a big calculation.

Not enough equipment

Node.js always gives great results when it is put to use. But many people have complained about bugs, poor quality, incomplete modules, and a lack of documentation, even though a talented Node community makes the npm modules and frameworks. On the other hand, expert Node.js developers can ensure that only the most useful npm modules and packages are used.


98 per cent of Fortune 500 companies use Node.js every day. Reasons? Very portable, quick, and able to grow. Since it is based on V8, this JavaScript runtime can also handle multiple requests simultaneously. Compared to other technology stacks, it saves you time and money while managing the traffic to your application effectively.
