Why You Should Use Node.js as Your Backend


The quality of backend development is the basis of every successful software development. If you are choosing a backend tech is a good idea to put your money on a tried and true one such as Node.js. In the end, the backend technology handles everything behind the scenes of web-based applications, such as managing connections between users, linking the app to databases, and supplying the app with numerous other functions.

Node.js is a runtime application environment that allows you to write backend programs in JavaScript. The technology provides a unique I/O model that works extremely well in high-demand, real-time situations that stress servers.

Letting developers utilize JavaScript in the application’s frontend and backend opens up new possibilities to reduce costs and achieve further efficiency. For example, businesses like LinkedIn and PayPal have moved backend programming to Node.js. Likewise, Uber, Netflix, and Trello used Node.js from the beginning.

Here’s why creating an application’s backend using Node.js is a great idea.

Why is Node.js to be used as a backend

Node.js is an excellent backend technology for a variety of reasons:

A single code base because of full stack JavaScript

In implementing Node.js as server technology, Your team will use the same language for both the front and backend components you have developed. As you can imagine, this speeds up the development process. As a result, your team is more interoperable and efficient. In addition, this results in fewer development costs.

Accessible technology

JavaScript is among the most popular programming languages worldwide. This means that your program’s codebase will be simpler to comprehend for new developers who join the project or substitute for those on holiday. In addition, the reality is that well-known JavaScript allows business owners to locate skilled JavaScript developers. Therefore, recruiting JavaScript developers will cost less than hiring engineers specializing in less well-known technologies.

Reusable code

Another benefit of making use of Node.js to be your technology for backends is that it permits teams of developers to share and reuse code shared between your frontend and backend sections. This is another advantage that speeds up your development.


One of the main advantages Node.js provides to projects is its scalability. Developers can easily scale their applications both in vertical and horizontal directions with Node.js. The only thing required to scale an application horizontally is adding additional nodes to the system. Furthermore, developers can add additional resources to single Nodes while increasing the size of the app vertically. This is the way Node.js is a highly adaptable technology for backends.

Active community

Node.js is an active community of eager developers to share their knowledge. They’ve created a great resource for tech-related knowledge. Look at StackOverflow, and you’ll find that the number of queries regarding Node.js is growing steadily. There is a constant increase in questions on the Node.js community is always growing as well.

The extensive toolbox

Node.js is accessible for free. Because it’s an open-source technique, Node.js also benefits from software developers’ dedication to developing its capabilities. In turn, companies like yours can benefit from an enormous range of tools that have been tested and proven. Node.js”package ecosystem” is the largest collection of open source libraries around the globe!

High performance

Node.js is renowned for its outstanding performance even when faced with large quantities of data that must be processed simultaneously. The technology interprets JavaScript code using the Google V8 JavaScript engine. The engine converts its JavaScript code into machine code and makes it simpler and quicker to create code. Another benefit of Node.js is that it speeds up the execution of code. In addition, the runtime environment can support non-blocking I/O functions.

What exactly is Node.js employed to accomplish?

Once you’ve figured out the advantages Node.js offers to projects that require software development and projects, you should think about possible applications. Here’s a list of solutions for companies using this technology, particularly in the backend.

Real-time applications (RTAs)

Real-time applications are digital tools we use every day, such as tools for managing projects, collaborative services, and audio/video conference programs, among others. For example, Google Docs or Slack are RTAs. Like many other real-time applications need heavy input/output operations. Node.js is a proven superior technology with its WebSockets and event API (not to add its event-driven aspect). With Node.js, companies can ensure that the data is instantly updated in these applications.

The most popular RTA usage is for chat applications. Node.js is a great choice for this type of application which requires massive data flows and traffic. On the other hand, chat applications also have to be light and speedy. The Node.js WebSockets can help manage the flow of messages in chat rooms.

Single-page applications (SPAs)

A single-page app means developers have the whole application on one page. It is a popular application among drawing/text tools, social networks, email, and other sites. Node.js is an ideal alternative to SPAs because of the synchronous data flow it has on its backend that allows for smooth data updates. This means that users aren’t required to refresh the site whenever they need to access new information. Node.js helps in its development for SPAs because of the reusability of the structures and methods for both the front and backend.

Data streaming apps

Another typical use for Node.js is streaming services such as Netflix. The advantage of Node.js for this purpose is the capability to process data by uploading it. In other words, apps can send a part of the content while keeping the connection open for downloading additional components. It’s not just about applications that deal with audio or video files -the same applies to audio and video data. Node.js can work with various formats to allow real-time input and output.


App programming interfaces (APIs) based on representational states transfer (REST) are crucial for any Software development initiative. REST APIs are getting more popular due to the growing trend toward microservices as design patterns. Node.js integrates the Express.js framework within its ecosystem, which allows developers to create rapid light REST APIs.

Monitoring dashboards

Another popular use case for Node.js is to create a system or application dashboard which displays information in real-time. You can, for instance, build a dashboard to track the number of visitors to your site, display their interactions with specific features, and then gather real-time data.

Hardware programming and IoT

We’re discussing robots, IoT, the Internet of Things (IoT), and embedded devices. Node.js is a well-known backend technology used by IoT solutions since it permits to process of multiple simultaneous requests made by various peripheral devices. Its JavaScript runtime environment functions as an intermediary between devices and databases. The event-driven, asynchronous design of Node.js lets for incredibly speedy data flow.

Key takeaway

Node.js is making waves in the world of web development with a vengeance. Its popularity keeps growing. Businesses looking to launch new products or services need large processing capacities for select data Node.js because it’s quick, lightweight, and offers a scalable platform.
