Java Spring vs Node Js

What is Java Spring

A lightweight framework in Java is termed a Spring, as it supports numerous frameworks, like Hibernate, Struts, Tapestry, JSF, EJB, etc., it can be viewed as a framework of frameworks. In a broader sense, the framework can be thought of as a framework where we can organize our efforts to solve various technical issues.

A number of modules, including Context, DAO, ORM, IOC, AOP, WEB MVC, etc., are included in the Spring framework. These modules will be covered on the next page. Let's start by comprehending IOC and Dependency Injection.

What is Node Js

A library used to build runtime apps is known as Node.js. Rayn Dahl originally created it so that JavaScript could be used outside of a browser, and Joyent eventually took over management of it. Both the front end and the back end of websites use Node.js, and programmers can also create mobile applications. With its powers, it can manage the server side, handle a user's packet request, and access the database all at once. 

There are a lot of frameworks for JavaScript that are dependent on NodeJs or ExpressJs. However, the choice to employ one of these frameworks will depend on the sort of application. Node.js has the benefit of being able to link to libraries created in other languages as well as devices through APIs.

Spring Vs NodeJs

Let us see the section below and understand the main points of comparison between Java spring and NodeJs.

1. Microservice:

Spring boot A microservice can be created using a Java-based open-source framework.
The platform Node.js, which is based on Chrome's JavaScript runtime, is ideal for quickly and simply creating scalable networking applications. To put it briefly, NodeJs is known as a runtime library and an application that is widely used to create server-side JS applications. Since Node.js is a free and open-source,  framework that allows for cross-platform scripting, developers regularly utilize it to build JavaScript apps. The scripts allow for quick writing and simple scalability.

2. Single and multi-threaded: 

NodeJs is single-threaded, which means that one thread may handle one request. The thread that is single is utilized to handle requests as they come in. The thread does not have to rely on the system database for fetching the data if a query needs to be made. Hence, a single thread will be utilized to start serving another request while the database is processing the particular query.

The notification is put in the Event Queue once the database has completed its duty. Node continuously keeps an eye on the queue. When the event is discovered, it is removed and placed under process. Because of this, Node is ideal for I/O-based applications that require extensive network connectivity. This will enable NodeJs to serve more clients without adding more hardware. And for this reason, NodeJs are adaptable. However, NodeJs has one drawback, which is that the client has to keep waiting whilst calculations are being done for one client. So NodeJs for image editing are not advised for CPU-intensive applications like video encoding.

3. Concurrency:

For enterprise-related web applications, the user requires high concurrency. Each request must have its own thread because Spring is multi-threaded, and as more threads are needed to achieve full concurrency, the system gets expensive.

Even though NodeJs is considered single-threaded, hence the CPU would be active when it is under heavy load, and the OS won't crash until the request is handled. There are no limits to NodeJs' popularity. The entire ecosystem has a transformative effect and broadens the scope of development as a whole. If you look at the StackOverflow example provided below, you'll see how revolutionary NodeJs' use is all over the world.

4. I/O Model: 

The framework or ecosystem that is used to construct software greatly depends on the input/output communication model. The act of displaying data and referring to it as the computer has displayed it is known as the I/O model. I/O calls are major of 2 types namely, non-blocking and blocking. The former implies that the thread is limited in what it can accomplish until the entire IO request has been received, whereas the latter suggests that if an I/O request has already begun its process, it can quickly implement further requests without having to wait.

Apps made using NodeJs are asynchronous and non-blocking. Blocking I/O is present in Spring boot Java. While Spring boot Java developers will have to wait for sending an I/O request, NodeJs programmers can send multiple queries at once.

5. Popularity:

Accenture, Google, Amazon, Microsoft, and a lot more businesses use Java Spring.

On the other side, Node.js is used by well-known firms like Uber, Netflix, NASA, Medium, Paypal, eBay, etc.

This is not to argue that these businesses only utilize that particular framework; rather, they simply announced their use of these technologies in public. Observe further that both frameworks are employed by outstanding technological firms.

6. Market Share: 

In terms of the top 100K global websites, Node.js is in the lead. In every market segment, Java Spring is trailing Node.js in market share.

7. Coverage:

NodeJs has more usage coverage over a wider range of website categories, including finance, arts & entertainment, automobiles, and many others. While Spring and NodeJs are equal in every website category

Advantages of Java Spring

• Lightweight: Thanks to its POJO implementation, Spring is considered a lightweight framework. It does not force the programmer to inherit any class and implement any interface. We may use POJOs to enable robust, scalable apps with the aid of Spring 
• It offers adaptable libraries that developers around the world rely on. For configuration choices, the developer has the option of using XML or Java-based annotations. A diverse range of capabilities and functionality is supported by the Dependency injection and IoC features. It simplifies the task.
• Because of dependency injection, Spring applications are considered loosely connected. It deals with injecting dependent components into a component without that component being aware of its origin.
• Strong Abstraction: It gives JEE specifications like JMS, JPA, JTA, etc. a strong abstraction.
• Portable: The user can make use of client-side business logic in swing apps and server-side business logic in web/EJB apps.
• Resource management: It is basically a cross-cutting issue that is simple to copy and paste anywhere.
• Configuration: It offers a uniform method of configuring things, the ability to distinguish configuration with application logic, and flexibility in configuration.
• Lifecycle: In charge of controlling each component of your program, especially those in middle-tier containers, which observe components through a defined lifecycle init(), destroy().
• Dependency Injection: Using dependency injection simplifies JavaEE programming.
• Rapid: Performance is extremely important to the Spring engineering team. It is quick because of its quick startup, quick shutdown, and efficient execution to sustain performance. Even using Spring Initializr, we can launch a fresh Spring application in a matter of seconds.
• Secure: It keeps a close eye on third-party dependencies. Our data and application are secure thanks to the constant updates that are released. The security in the Spring framework can be used to secure our application. It delivers a reliable solution that is safe by default and offers industry-standard security protocols.

Advantages of NodeJs

• Scalability: The ease with which Node.js allows programmers to grow programs vertically and horizontally. This is one of its key advantages. The programs could be scaled horizontally by adding more connections to the existing system.
• Easy Learning: Since JavaScript is among the most widely used programming languages, the majority of front-end developers are proficient in it.
  The users discover that starting to use Node.js mostly on the back server is significantly easier. Working with Node.js takes less time and is easier to learn.
• Single programming language: It is all because of  Node.js that developers now have the option of creating server-side apps on JavaScript. Because of this, Node.js developers may use a runtime environment to write JavaScript code for both the front-end and the back-end of a web application.
  Additionally, they are not required to employ any additional server-side programming languages. Because practically all web browsers support JavaScript, it also facilitates the deployment of online apps.
• High Performance: As was previously noted, Node.js uses Google's V8 JavaScript engine to interpret the JavaScript code. The JavaScript code is directly converted into machine code by this engine. This makes effective code implementation simpler and quicker.
  Because it provides non-blocking I/O operations, the runtime environment also enhances the speed of code execution.
• Caching: The Node.js open-source runtime environment offers the capability of caching individual modules as well. The first module is cached in the program memory and is made available upon request.
  Because caching enables programs to load web pages more quickly and reply to users more quickly, developers don't need to execute their codes again.
