Node.js Vs. Java Which One Should You Choose For Backend Development - Moon Technolabs

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.

  • 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 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.

  • 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.

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.

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.

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.

2. The 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 app architecture - Moon Technolabs

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.

3. 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.

App testing with Moon Technolabs

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.
