3. 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?
Introduction

4. 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.

5. 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.
● 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.
● During the first half of 2020, 51.4% of all developers described Node.js as the most
widely-used development tool.
● 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.
About Node.js

6. 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.
● Java is at the heart of about 3.4% of all websites on the internet.
● Java is part of about 96,037 websites, and it has 51,346 exclusive domains.
● 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.
About Java

7. ● 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.
Advantages of Node.js

8. ● 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.
Disadvantages of Node.js

9. ● 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.
Advantages of Java

10. ● 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.
Disadvantages of Java

11. 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.
Performance

12. 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.
The app architecture

13. 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.
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.
App testing

14. Even for the top mobile app development companies like Moon Technolabs, choosing
between Java and Node.js can be a challenge. Naturally, it’s going to be difficult for you too.
You can overlook the information provided here, yet make the right choice if you stick to the
points given below.
Your choice should be Node.js if your project qualifies for the following pointers.
● You want to create a web app for content streaming purposes.
● You want to build a high-performance SPA.
● You want to create web apps enriched with powerful data processing abilities.
● You want to create game applications that’ll run on web browsers.
Conclusive statements

15. Your choice should be Java if your project fulfills the following requirements.
● You want to create enterprise-level apps.
● You want your app to be fully scalable.
● You hope to leverage a fully mature framework that has the highest levels of
community support.
● You want to build big data apps or e-commerce solutions
With this final bit of information, you can decide between Java and Node.js for your project
if you find everything else difficult to contemplate. For further information, you can contact
a reputable and experienced app development agency.
