Node Js vs Spring Boot: Which One To Choose?

Node Js vs Spring Boot: Which One To Choose?

A company can be transformed by a number of server-side technologies. A meal delivery service is changing the way people order food, and an online marketplace is changing the way people shop. So, if you need to see a doctor, you can do it all online. Doctor consultations are now available through video conference, saving time for both doctors and patients who would otherwise have to go to the doctor's office.

You can use a wide range of technologies to make your company available online, like Node.js, Java Spring Boot, and Python. In this article, we'll compare Node.js and Java Spring Boot to see which is better for building microservices apps.

Why Choose NodeJS?

Node.js is a single-threaded, non-blocking event-driven I/O framework written primarily in JavaScript. Therefore, it's extremely efficient and light. It is perfect for applications that need to run in real-time across multiple devices and have a lot of data.

Why Choose Spring Boot?

Spring Boot is a Java framework for developing standalone, production-ready applications. Spring Boot inherits the bulk of Java techniques and features from the Java Spring ecosystem, making it a fantastic choice for your next commercial application.

Because of its support and protection for multi-threaded programming, Spring Boot Development has been the chosen alternative for many users whose primary worry was the integrity of their application. The protection of the Spring Boot Application is unaffected by the fact that it is based on Java. As a result, many customers choose the Spring boot framework to build business applications that place a high value on security.

Node JS Framework vs Spring Boot Framework: Overview

Since one is a coding language while the other is run-time, it may seem strange to compare them. However, when we decode the Java architecture, we can see that Java has grown into its own ecosystem, equipped with plugins, APIs, and libraries. A virtual computer with a run-time ecosystem is also included.

Java is a more than 20-year-old programming language that was created by Sun Microsystems and was later acquired by Oracle, the current owner. It's been in charge of server-side programming for a long time.

Spring boot is a Java framework that allows for the faster launch of production-grade and standalone programs. It's a bootstrap edition of the spring platform that's not only simple to use but also cuts down on the steps required to get the app up and running.

It's all about connections, with a heavy reliance on annotations and XML. With these annotations, the configuration procedure becomes easier, which becomes more difficult as the project grows larger and has more dependencies.

NodeJs is not a programming language in the traditional sense; rather, it is a runtime that enables the execution of JavaScript on the server. JavaScript is a language that has been used on the client-side for nearly as long as Java.

Node JS Framework vs Spring Boot Framework

Single vs Multi-threaded

Because NodeJs is single-threaded, it can only handle one request at a time. The requests are handled by a single thread. If a database must be queried, the thread does not have to wait for the database to return the results. The single thread will be used to serve another request once the database has completed the relevant query.

The notification is put in the Event Queue once the database has completed its duty. A node keeps a constant eye on the queue. When it recognizes an event, it eliminates it and processes it. As a result, Node is ideal for I/O-based applications that require a lot of network connectivity. This will allow a NodeJs development firm to serve a larger number of customers without adding additional hardware. That is why NodeJs is so adaptable. However, there is one drawback to NodeJs: when processes are done for one user, the other users must wait. As a result, NodeJs is not recommended for CPU-intensive applications such as video transcoding or image editing.

Boots for spring Java, on the other hand, is multi-threaded, which implies that it can handle multiple jobs at the same time.

Multithreading, in a nutshell, improves the performance of applications. As a result, Java is suggested for large-scale projects involving several processes, but Node.js does not handle threads as well as Java.

I/O model

The I/O communication mechanism has a significant impact on the framework or ecosystem used to develop software. The process of showing data and referring to it as shown by the system is known as the I/O model. There are two sorts of I/O calls: blocking and non-blocking. While the former suggests that the thread won't be able to do anything until the entire IO is delivered, the latter says that if an IO request is currently in progress, it can quickly implement further requests without having to wait.

In NodeJs, developers can send multiple requests at once, whereas in Spring Boot Java, developers must wait for each I/O request.

High Concurrency

High concurrency is required for enterprise web applications. As previously stated, Java is multi-threaded, and because each request requires its own thread, it will require a large number of threads to achieve concurrency. When the number of users increases, the cutting time between these various threads becomes a costly endeavor. When the number of threads increases, the operating system gets very busy, reducing the amount of time that the CPU is available to accomplish work.

This is where Node J’s performance comes into play. When NodeJs is operating at maximum load, the CPU will be occupied, but the OS will not crash, and the entire CPU time will be spent doing what you're supposed to do, which is servicing the requests.


High concurrency is necessary for enterprise web applications. Since Spring Boot is multi-threaded, it needs a thread for each operation, and achieving full concurrency requires multiple threads.

Because Node Js is single-threaded, the CPU will be occupied while the system is under heavy load, and the operating system will not crash until the request is completed.


The Spring Boot framework is used by companies such as Microsoft, Google, Accenture, Amazon, and more. The Node Js framework is used by companies such as Medium, Paypal, Netflix, Uber, NASA, eBay, and more.

This isn't to claim that these businesses just employ that framework; rather, they have openly stated that they use certain technologies. Also, note that both frameworks are used by great technology businesses.

Node JS Framework vs Spring Boot Framework


To sum up, both technologies are incredible in their own right, and we can't truly present the best prize to either of them. Both technologies are declared winners.

If your program needs a lot of I/O tasks, the NodeJS framework is the way to go; if you need a tough, protected, and standalone program that takes a lot of CPU time, the Spring Boot framework is the way to go.
