When it comes to building the backend of your web or mobile application, choosing the right technology stack is crucial. The backend is responsible for processing data, running server-side scripts, and communicating with the database. Node.js and Java are two of the most popular backend technologies in use today. In this article, we’ll compare Node.js vs Java to help you choose the best technology for your project.
What is Node.js?
What is Java?
Java is a high-level programming language developed by Sun Microsystems. It is used for building web applications, mobile applications, and desktop applications. Java is compiled into bytecode, which can run on any platform with a Java Virtual Machine (JVM). Java is known for its stability, scalability, and security.
Node.js vs Java: 360-Degree Comparison
In contrast, Java is a highly dependable and secure programming language that differentiates itself from other technologies, particularly Node.js. One of Java’s significant strengths is its multithreading support, which allows for the simultaneous execution of multiple processes and the efficient utilization of CPU resources. Additionally, Java’s bytecode compilation allows for easy portability and platform independence, allowing the code to run on any machine or operating system without modification.
Java’s other essential features include robust memory management and concurrent accumulators that contribute to the application’s reliability and performance.
Developers’ lives are simplified by the availability of various libraries in both Java and Node.js.
When deciding between Node.js and Java, several factors should be taken into account. Node.js is preferred for its agility, scalability, and ease of use, making it an excellent choice for developing applications that require quick response times and efficient use of resources. On the other hand, Java’s robustness and reliability make it the ideal option for building enterprise-level applications that require high-level security and performance.
Node.js vs Java: Stability
Java is known for its stability due to its rigid structure and time-proven interfaces, while Node.js can be less stable because it’s designed for interacting with APIs that may change and cause instability issues for applications built in this environment.
Node.js vs Java: Scalability
Node.js is an ideal tool for developing highly scalable applications, thanks to its non-blocking input and output system and event-oriented model, allowing it to handle multiple concurrent requests. Node.js also uses a distributed system for different types of services, providing scalability and efficiency. Meanwhile, Java is a popular choice for enterprise application development due to its scalability and superior performance.
Node.js vs Java: Documentation
Both Node.js and Java offer extensive documentation that developers can use to learn new features and capabilities. Node.js documentation includes API reference documentation, ES6 features, and guides, while Java’s documentation provides a vast database of language-related information.
Node.js vs Java: Community
Node.js has gained popularity in recent years, thanks to significant contributions from tech giants such as Facebook, Google, and Amazon. In contrast, Java has a more established community with a long history of usage and support.
Node.js vs Java: The talent pool
According to the enterprise app today survey, Node.js ranks first in the “most wanted” category for frameworks, libraries, and tools, while Java ranks fifth in the “most used” languages and tenth in the “most loved.” Both have a large talent pool worldwide, with 23 million developers in 2018 and an expected increase to 27.7 million by the end of 2023.
Node.js vs Java: Ease of learning
Node.js vs Java: Speed of coding
Node.js has a slight edge in coding speed due to its extensive collection of community-created libraries and reusable components. According to former PayPal Director of Engineering and Chief Architect Jeff Harrell, Node.js apps require 33% fewer lines of code and 40% fewer files, resulting in faster development time. However, development time can vary depending on the project type, team size, and the team’s language proficiency.
Node.js vs Java: Installation
Before working with Node.js, the first step is to ensure the archive file is present on the system. Developers should download the NodeJS .msi installer and execute it. After the installation is complete, it’s essential to verify that the installation is successful. To do so, launch the command prompt and execute the command:
$ node -v
If the installation is correct, the command will return the version number. For example:
$ node -v v6.9.5
If the command above doesn’t return any results, developers may need to uninstall and reinstall NodeJS.
In contrast, installing Java requires setting up the JavaFX environment to run JavaFX applications. The process begins with downloading the JDK to the system, installing it, and setting the path permanently.
- Open the command prompt
- Type “java -version” and press enter
- If Java is properly installed, you will see a message similar to
- Java version “1.4.x_xx”
- Java SE Runtime Environment
- Java hotspot Client VM
If the message “command not found” appears, developers may need to uninstall and reinstall Java on their system.
Node.js vs Java: Database Support
Furthermore, Node.js features a specialized object data-modeling library that is specifically designed to work with MongoDB. This improves developer productivity by making the code more readable and flexible.
Java, on the other hand, provides support for a wide range of databases and uses the standard Java Database Connectivity for accessing data in applications. Some of the most commonly used databases with Java include MySQL, SQLite, and PostgreSQL.
To build simple projects, developers can utilize built-in Java databases, while JDBC-enabled databases can solve the problems associated with relational databases.
Node.js vs Java: Cost of Development
Based on Glassdoor estimates, the average salary for Java programmers in the United States is approximately $90,000, while Node.js developers earn an average of $105,000. In India, the average salary for a senior Java developer is $10,496.16, which makes Java development more cost-effective in the Indian market.
However, when it comes to working with freelancers or outsourcing development, pricing can vary significantly. Several factors, such as project complexity, management, and potential drawbacks, can impact cost estimates, making it challenging to provide an exact figure. To obtain a more accurate idea of the expenses, it is recommended to request quotes from various Java and Node.js development companies.
