Advantages and Disadvantages of Node.js

Advantages and Disadvantages of Node.js

Node.js is an open-source JavaScript platform for easily developing server-side and real-time networking applications using a runtime environment. It is built on Chrome’s V8 JavaScript engine. It has a non-blocking, event-driven input-output model, making it efficient and lightweight. It uses a single-threaded event-based loop to ensure that no executions are blocked. However, Node.js is not a framework and has nothing to do with PHP, .NET, or Java.

Node.js has emerged as the preferred framework for many industries, including IT, healthcare, and others. The ease of use that Node.js provides is difficult to ignore. Every technology does, however, have some benefits and drawbacks. Node.js has played a significant role in the significant changes in web development. Let’s examine the key advantages and disadvantages of using Node.js for server-side programming.

Advantages of Node.js

Node.js excels at building fast, scalable network applications, and it provides benefits such as improved performance, faster development, and other advantages. Here are other advantages of Node.js.

  • Easy Scalability
  • Easy to Learn
  • Single Programming Language
  • Benefit of Fullstack JS
  • Offers High Performance
  • Support of Large and Active Community
  • Offers the Freedom to Develop Apps

1. Easy Scalability

Developers find it simple to scale applications in horizontal and vertical directions, which is one of Node.js’ main advantages. Adding more nodes to the existing system can scale the applications horizontally.

In addition, Node.js gives you a choice to add extra resources to single nodes while vertically scaling the application. It, therefore, offers more options than other JavaScript servers and is highly scalable.

2. Easy to Learn

Most front-end developers have a solid understanding of JavaScript because it is one of the most widely used programming languages. They find it much simpler to begin using Node.js for the back-end. Node.js takes less time to work with and is simpler to learn.

3. Single Programming Language

Developers can write JavaScript server-side applications using Node.js. Node.js developers use a runtime environment to write JavaScript front-end and back-end web applications. They do not require any other server-side programming language. JavaScript has widespread support in web browsers. Therefore, it facilitates the deployment of web applications. 

4. Benefit of Fullstack JS

Node.js has been regarded as a full-stack JavaScript for client and server-side applications. Node.js is a full-stack Javascript that serves both client-side and server-side applications. So it can benefit by not having to hire a separate developer for back-end and front-end development. Time and money can also be saved.

5. Offers High Performance

As mentioned earlier, Node.js uses Google’s V8 JavaScript engine to interpret the JavaScript code. This engine directly converts the JavaScript source code into machine code. It facilitates the quick and simple implementation of the code. The runtime environment, which supports non-blocking I/O operations, also speeds up code execution.

6. Support of Large and Active Community

Node.js is fortunate to have a large and active developer community constantly contributing to its continued development and improvement.

  • JavaScript programmers who provide ready-made and simple solutions and codes on GitHub provide excellent support to developer groups. 
  • Developers from all backgrounds can connect in the Node.js Community to exchange ideas, pick up new skills, and help with various projects. 
  • This community is also active on GitHub. 
  • In the future, these developers are expected to initiate many more developers.

7. Offers the Freedom to Develop Apps

Node.js offers the freedom to develop apps and software from scratch. It is an essential feature that remains absent in Ruby on Rails. 

Disadvantages of Node.js

After the impressive advantages, it’s important to understand the drawbacks of Node.js as well. What Node.js lacks are listed below.

  • Unstable Application Programming Interface (API) 
  • Not effective with Large Scale Applications
  • Lack of Library Support
  • Asynchronous Programming Model
  • Unavailability of Experienced Node.js Developers

1. Unstable Application Programming Interface (API) 

One of the most significant issues that most developers face is that the Application Programming Interface (API) changes frequently and does not remain stable.

  • At times, a new API with several incompatible changes appears. 
  • As a result, developers are forced to modify the accessible code bases to ensure compatibility with the most recent version of the Node.js API.

2. Not effective with Large Scale Applications

Node JS is only preferred for lightweight applications (online games, chat), as it does not support multi-threaded programming. If you’re going to use it for heavy applications, you’ve made the wrong decision.

3. Lack of Library Support

JavaScript does not have a robust library system compared to other programming languages. As a result, users are forced to rely on a common library to perform tasks such as Object-Relational Mapping (ORM), image processing, database operations, and XML parsing, among others. It makes it difficult for developers to implement even basic programming tasks in Node.js.

4. Asynchronous Programming Model

Adopting the asynchronous programming model is necessary to make your applications more scalable. Many developers, however, may find this programming model more difficult than linear blocking I/O programming. Another disadvantage of asynchronous programming is that the codes become clumsy, forcing programmers to rely on nested calls.

5. Unavailability of Experienced Node.js Developers

The potential demand for Node.js developers grows year after year, but there aren’t enough experienced developers to meet it. Furthermore, businesses must recognize that not all JavaScript developers are also Node.js developers. 

  • Because developers must understand backend development in order to master JavaScript.
  • As a result, despite the fact that there are millions of JavaScript developers, it is difficult to find a skilled Node.js developer. 
  • That is why companies are looking to outsource their Node.js development projects these days.

It is obvious that the advantages of Node.js outweigh the disadvantages. Businesses must also define their requirements in addition to understanding the advantages and disadvantages of Node.js. Node.js has everything you need to grow your company, but you must use it properly.
