This write-up compares two of the most preferred and widely used backend technologies in app development projects. The
participants are Node.js and Java. Here you’ll learn about the differences between and two so that you can make an
informed decision for your project.
At the moment, Node.js and Java are two of the most powerful technologies for app backend development. Even Netflix
designed the backend of its app using Java, but the company switched to Node.js later.
This topic will explain why and how Java retains its relevance in modern times like this and what makes Node.js so scalable.
Based on the fact that Netflix shifted to Node.js from Java, it should be clear that the former can outrun the latter, but in
which areas?
Here you’ll find the answer to this question. The information provided here will also help you decide on the right backend
technology for the web app project you have in your pipeline. You’ll understand whether it’ll be beneficial for you to hire
dedicated node developers or Java experts.
About Node.js
Node.js is fundamentally a server-side runtime environment based on JavaScript. It boasts of an immensely large
open-source tool. Node.js is popular because it’s a scalable, high-performance framework that facilitates the single-thread
method used by developers for async programming and web loads.
1. StackOverflow released the Developer Survey report two years ago. This report found that almost 66.8% of all
developers are in love with Node.js.
2. During the first half of 2020, 51.4% of all developers described Node.js as the most widely-used development tool.
3. About 85% of all Node.js developers use the framework for web app projects. Conversely, 43% of all developers use
it to create enterprise-grade digital products.

4. About Java
Java is one of the oldest programming languages promoting the use of object-oriented concepts like C++. It adheres to the “write once and
run everywhere” strategy. In other words, code created using Java can work on all platforms supported by Java without recompiling anything.
Created by Sun Microsystems in 1991, Java is now the property of another company called Oracle. This programming language is flexible,
secure, and stable.
1. Java is at the heart of about 3.4% of all websites on the internet.
2. Java is part of about 96,037 websites, and it has 51,346 exclusive domains.
3. The Annual Survey report of StackOverflow that came out in 2020 ranked Java among the top five popular programming languages. In
reality, Java has held this position for the last eight years.
The advantages and disadvantages
As already mentioned earlier, Node.js trumps Java in some instances. In the same way, Java can outrun Node.js, but it depends entirely on the
project you have at hand. If you want to hire dedicated node developers from an organization like Moon Technolabs, you should check out
the pros and cons of both technologies.
Advantages of Node.js
● Not opinionated
Node.js isn’t opinionated and builds everything from the beginning with only a few restrictions. As a result, developers can enjoy the freedom
of coding the way they want to.
● The I/O system doesn’t block
The I/O system of Node.js doesn’t block anything. It lets your developers process multiple requests at the same time. As a result, Node.js
performs faster and is more scalable too.
● An active community
Node.js has an active community that provides access to readily available codes and solutions. For rookie developers and startups, this
feature is priceless.

5. Disadvantages of Node.js
● Loss of productivity
In Node.js, developers have to write everything from scratch. As a result, using it will affect productivity.
● Extensive computing inability
Indeed, Node.js can support some of the most complicated applications, but it won’t work well with CPU-intensive
applications.
● Difficulty in maintaining code
The nested callbacks in Node.js and the dependence of the framework on asynchronicity makes it difficult for developers to
maintain the code or even understand it.
Advantages of Java
● Pocket-friendly development
Applications designed using Java are OS and browser agnostic, at least in terms of testing. As troubleshooting and
configuration are simple enough, the lifecycle of development becomes pocket-friendly.
● Better security
Java facilitates app deployment on dedicated servers. As a result, it makes app monitoring and maintenance seamless for
server administrators.
● Interoperability
Developers can integrate apps designed using Java with other business solutions. This feature makes the language
interoperable for web apps and isolated apps for desktop devices.

6. Disadvantages of Java
● Memory-hogging
This framework tends to consume a lot of memory and it’s slower than other natively-compiled programming languages, such as
C++ or C.
● Problem with Android API
App development experts recommend staying away from Java to build apps for Android devices. It has specific limitations
associated with code maintenance and improving app codebase.
● No backup facility
Java prioritizes storage instead of backing up data. This drawback drains the interest of developers.
1. Performance
Whether you choose a node.js development company or a Java development firm, you should gauge the performance standards of
both platforms first.
Performance of Node.js
Node.js possesses the non-blocking and asynchronous functionalities from JavaScript. As a result, it creates an appropriate
environment for the smallest tasks without affecting the primary app thread. Additionally, the V8 engine of JavaScript and the
multitasking capabilities of Node.js contribute to its performance.
Performance of Java
Developers have to write programs in Java in the form of byte codes. This feature allows the language to work better and faster
than every other conventional programming language. Virtual machines can interpret these byte-code instructions and deliver
much more efficient apps within the shortest period.

7. 1. e app architecture
When picking a framework for your project, you must prioritize flexibility while avoiding strict architecture and
guideline-related enforcements. If you work with a node.js development company like Moon Technolabs, the developers
working there will ask you to treat the framework of your choice as a guide instead of standards or methods.
The architecture supported by Node.js
Node.js utilizes the architecture of a single-threaded event loop. It enables Node.js to handle several requests at the same
time without affecting performance. Node.js also facilitates using the architecture pattern of MVC or MVP that eases
onboarding and isolating issues in the application codebase.
The architecture supported by Java
Developers usually prefer using the MVC pattern to create apps in Java as this model represents the objects in the
programming language. Also, the design pattern matches the internal architecture of Java. Furthermore, Java promotes
ease of code maintenance and hassle-free app testing.
2. App testing
The only way to ensure that your app works seamlessly under constant load and manage the ever-growing market
expectations is to conduct a series of rigorous tests. In doing so, the top mobile app development companies deliver an
app that’ll be compliant with usability, UI standards, and compatibility.
Testing apps on Node.js
Node.js delivers competent inspection and debugging abilities with its powerful ecosystem of packages from third parties.
The automated testing frameworks or tools, such as Jest, Mocha, Lab and Code, AVA, and Jasmine can create an effective
ecosystem of app inspection.

8. Testing apps on Java
Java lets developers create test cases. Therefore, your developers will be able to prepare flexible inspections with grouping,
sequencing, and data-driven features. Additionally, Java simplifies writing parallel tests. It facilitates several testing tools and
frameworks, including Selenium, JUnit, Apache JMeter, TestNG, and FitNess.
