Spring Boot Vs Node JS

Spring Boot Vs. Node.Js: Difference Between Spring Boot And Node JS

There is hype between the users to choose the server-side language. Several server-side technologies are available, But which language is secure and easy to use, it has always been one of the most frequently asked questions. In this topic, we are going to distinguish the two most popular and commonly used technologies, that is Spring Boot & Node JS. In this article of learning Spring Boot Series, we will see Spring Boot VS Node JS. Further, we will see which one is more useful and trendy.

Spring Boot Vs Node JS

Before diving into the topic, let’s have a quick overview of both the technologies:

What is Spring Boot

Spring Boot is a Java Framework that is used to develop web-based enterprise applications. It is trendy among developers because it provides some extensive features such as auto-configuration to reduce the developer’s effort.

The Spring Boot Framework is popular for developing & managing Java enterprise applications. It can be used with other Java frameworks like Hibernate and Struts; It provides a production-ready application. There is no requirement to create configurations in Spring Boot because Spring Boot automatically does all the basic configurations. It supports an embedded server in jar files.

As the Spring Boot is a Java Framework, it inherits all the Java features by default, making it a good technology to choose for the business. Spring Boot provides secure and multithreaded applications.

Due to its security and easy maintenance of code, it’s always been a favorite choice. It provides security with Java’s trust.

Advantages of Using Spring Boot

Some useful features of Spring Boot are as following:

  • Spring Boot applications are easy to develop.
  • It provides many features such as auto-configuration, YAML support, which saves time and increases productivity.
  • It avoids boilerplate codes, annotations and XML configurations.
  • The SB projects are very easy to integrate with the Spring ecosystem, such as Spring JDBC, Spring ORM, Spring Data, Spring Security, and more.
  • It provides opinionated Default Configurations, which is useful for reducing the effort of the developer.
  • It provides embedded HTTP servers for enterprise applications.
  • It Supports CLI for developing and testing the applications from the terminal.
  • It supports various plugins for developing and testing applications.
  • It supports plugins for working with embedded and in-memory databases.

What is Node JS

Node.JS is an open-source server-side javascript runtime environment used to develop fast and scalable web applications. It is a lightweight, efficient & superb tool for data-intensive real-time applications.

It supports event-driven, non-blocking I/O and cross-platform runtime environment for developing server-side applications. The Node applications are highly scalable. It can be used in different applications such as web applications, command-line applications, real-time chat applications, Rest applications, etc. But, it is primarily used to build network programs such as web servers.

Node.js introduced to the market in 2009 by Ryan Dahl.

Advantages of using Node JS

Some useful features of Node.js are as following:

  • It is an open-source framework distributed under MIT ( Massachusetts Institute of Technology) license.
  • It uses JavaScript to build server-side applications.
  • It is a lightweight framework that requires minimum modules.
  • It is faster than other frameworks.
  • It is cross-platform can be run on different operating systems such as Windows, MAC or Linux.

Disadvantages of Both Spring Boot & Node.js

Disadvantages of using each technology are listed in the below table:

Spring BootNode.js
It has high memory utilizationIt does not support multithreading
In Spring Boot, Java is verboseIt has a lack of strict type checking that can lead to run time problems.
SB application has lots of boilerplate code, which makes debugging tough.It is not so good for heavy computing performance.
It may contain unused dependencies.
It does not contain unused dependencies.

let’s talk about their performance:

Performance Comparison of Spring Boot & Node JS

Below is some performance comparison of Node.js & Spring Boot:

Node is Single Threaded While Spring Boot is Multithreaded

Node JS is Single Threaded, which means one request can be handled with one thread. If a request is made, a single thread will deal with it. If we need to query the database, the thread needs not to wait for the database to fetch it. When the request is completed, the single thread will serve the other request.

After the database completes its task, the message is published in the event queue. The Node will monitor the queue instantly. When it acknowledges the event, it removes it from the queue and puts it in the process.

This makes the Node best for the I/O operations and provides several network access. It makes Node highly productive & flexible without utilizing more hardware.

Its major disadvantage is that while calculating one client, other clients have to wait. Hence, the Node is not recommended for CPU-intensive applications such as video encoding, image manipulation, etc.

Consider the below image that illustrates the single-threaded and multithreaded processes:

Multi-threaded Server

Comparatively, Spring Boot supports multithreading, which means we can perform several tasks simultaneously. Multithreading assists the application to perform better. For the large scale applications that have multiple tasks, Spring Boot is recommended compared to Node.

I/O model

The I/O model is responsible for the process of displaying the data. So it is also an important factor for choosing a framework. The I/O calls are two types.

  • Blocking
  • Non-blocking

Node.js apps are non-blocking and asynchronous while the Spring Boot has blocking I/O calls. I/O calls the thread in the blocking can’t be executed until the entire I/O is fully received. The Non-blocking I/O calls can easily implement other requests without the need for other requests to wait.

The Node can send many requests at a time comparatively in the Spring Boot; we have to wait for every I/O request.

High Concurrency

Enterprise web applications require high concurrency. Java is multithreaded and contains a dedicated thread for each request. So, it will demand multiple threads to achieve concurrency. In case no of users increases, the execution time between these threads becomes high. In such scenarios, the Node works more efficiently.

Hence, we have discussed the performance parameters. Let’s talk about their specialties:

Why Node JS

Below are some considerable points for using Node.js as your favorite framework:

  • Using Node.js, application development is easy to start due to supported prototype options.
  • It follows the agile development methodology, which is ideal for highly scalable application development services. So, some tech giants like Netflix, Paypal are using it for superfast development.
  • As it requires fewer configurations so, the development with Node is faster than other Frameworks.
  • It has a faster response time for the requests.
  • It has an event-driven development.
  • It supports non-blocking I/O calls.
  • It is a lightweight framework and great for data-intensive applications.

Why Spring Boot

Below are some considerable points for using the Spring Boot as your favorite framework:

  • The trust of Java security is well known among developers. It provides built-in security features for web development.
  • Almost all devices and operating systems support Java.
  • The Spring Boot provides production-ready applications.
  • It has minimal configurations.
  • It provides robust code that allows us to easily debug the code.
  • It provides a great garbage collection mechanism with an extensive type of checking the scale.
  • The Integration capabilities of Spring Boot are great.
  • Java is a reliable language and supports all major client-technologies as well.
  • It is stable as it implements the Java Class Library.
  • Its cross-platform support makes it more valuable and makes the development easy.
  • It avoids writing the boilerplate code and XML configurations.
  • It is straight forward to build the Java Enterprise applications by reducing the development time.
  • It increases productivity.
  • It provides embedded HTTP servers like Tomcat, Jelly.
  • It provides easy testing for web applications.
  • It supports a command-line interface, which is great for developing and testing the Spring Boot applications from the terminal (Command Prompt).


As we have discussed, both technologies. Now, you may still question which one is better for your business or to learn. So, let me make a final note to the discussion:

Both technologies are good to learn, and business starts up. If you are building a project that requires tons of I/O processing, you must go with Node to provide a superfast speed and quick response. If you are building a project to perform a huge amount of computing processes such as (IOT, eCommerce website, or Big Data) the Spring Boot would be the preferable choice.

We can’t say which technology is better both have their separate fan following. Most people love the power of secure Java more than any other technology, and most people want to go with the super easy JavaScript. So totally the choice is yours.

Our main concern is Node.js is less secure and capable of handling heavy computing than Java. But, we hope the JavaScript community will eventually come through and eliminate this problem.
