Here are the Advantages and Disadvantages of using Node.js

There is no doubt that JavaScript, specifically Nodejs, is one of the widely used client-side programming languages by developers. JavaScript is employed as front-end development and proves to be quite handy for building cross-platform applications.

JavaScript has also a great reputation due to its usage in other popular platforms such as PhoneGap, Apache, NativeScript, Accelerator, Titanium, and more.

In the current area, the area of application of JavaScript has widened, and now it is also being utilized as server-side programming. Nodejs has played a crucial role in this major shift in web development.

Nodejs found applications in almost every application that we use in our day-to-day lives. The applications like Netflix, Uber, Ola, Book My Show, and more, which receive a lot of traffic every day from various geographic locations, are built using Nodejs. Nodejs aids in the smooth and flawless operation of these applications.

Here is a detailed explanation of what Nodejs is all about, why you should choose it for web development projects, and what are the pros and cons of Nodejs.

What is Nodejs?

As mentioned above, JavaScript is one of the popular and versatile languages for developing the frontend web. Nodejs is a framework of JavaScript that is being employed in many applications and server-side programming. 

Serving-side programming involves the creation of content for the web page on the server end. And Nodejsplays an important role in server-side programming. Being an open-source JavaScript framework, Nodejs also aids in the development of network and web applications.

Nodejs manages browser requests and offers asynchronous, event-driven I/O APIs to fetch the results not only speedily and accurately. It runs a single-threaded event-based loop, hence all the executions become non-blocking.

Here, it is important to note that:

  • Node is a server and not a framework.
  • Node wrappers over JavaScript V8 Runtime are made in C and not in JavaScript
  • It runs in a single thread with a callback concept.

Advantages of NodeJS

Advantages of Node.js

Here are the advantages of using Nodejs for server-side programming:

1. Easy to learn:

Most developers have a good grasp of JavaScript for it being one of the most popular programming languages.

Developers who are already good in JavaScript find it easy to use Node.js at the backend. It is quite easy to learn Nodejs and it also consumes lesser time.

2. Supported widely by Google Chrome:

The search engine is empowered by Node.js and it not only aids in the front-end development but also has a great impact on the backend. Nodejs is supported by the Google V8 engine, which has the power to execute at the same time in the front end using JavaScript.

Google lists Node.js as one of the fastest runtime system engines so that’s amazing. Also, with Nodejs it is easy to find mistakes in the front end as well as the back end.

3. Node.js offers easy scalability:

One of the key benefits offered by Nodejs is that it makes it easy for developers to scale the application in horizontal as well as vertical directions. The application can be scaled in a horizontal dimension by adding extra nodes to the current system.

Furthermore, Node.js also allows adding extra resources to a single node during the vertical scaling of the application. Hence, NodeJS is highly scalable and offers greater options than other JavaScript servers.

4. Full-stack JavaScript:

Node.js has regarded as a full-stack JavaScript for serving server-side applications as well as the client.

The benefit of using Nodejs is that you need not hire remote developers for the front-end and back-end, which saves you valuable money and time.

5. Offer High Performance:

As mentioned earlier, Node.js interprets the JavaScript code through Google’s V8 JavaScript engine. The engine compiles JavaScript code directly into the machine code. Hence, it becomes easy to implement the code. Moreover, it can be done quickly and in an effective manner.

6. Single Programming Language:

With Node.js it becomes possible for developers to write the server-side application in JavaScript. This means that when you Hire Nodejs developers they can write both front-end and back-end applications in JavaScript using a runtime environment.

7. Large and Active Community:

Node.js have a large and active community of developers who keep on contributing to the further improvement and development of this server-side JavaScript.

Developers working on Node.js have been supported well by JavaScript programmers who provide them with easy and ready-made solutions and codes in GitHub.

8. The ability of Caching:

The open-source runtime environment of Node.js provides the ability to cache a single module. The entire request for the first modules gets cached in the application memory.

9. Support for Commonly Used Tools:

With Node.js, developers receive extended support for various commonly used tools. If you want to test the source code of the Node.js application, you can do it by using Jasmin and other such testing tools.

Similarly, if you want to install or identify the project dependencies, you can make use of npm, which is a powerful package manager. 

10. Handles Requests Simultaneously:

Node.js provides the option of non-blocking I/O systems. It helps you to process several server requests simultaneously.

Node.js system can handle concurrent requests better than Ruby or Python. The incoming requests get lined up and are addressed quickly and systematically.

Disadvantages of using Node.js

Disadvantages of using Node.js

1. API is not stable:

One of the key problems that developers encounter while working on Node.js is the Application Programming Interface keeps on changing at frequent intervals and does not remain stable.

At times, you will see a new API with multiple backward-incompatible changes. As a result, developers are obliged to make changes in the accessible code bases to remain in tune with the latest version of Node.js API.

2. Library Support System is not strong:

Compared to other languages, JavaScript does not have a robust and well-equipped library system.

As a result, users are forced to take support from the commonly available library for executing tasks, such as processing and handling database operations, Object-Relational Mapping, XML parsing, etc.

This makes it difficult for developers to implement common programming tasks using Node.js.

3. Asynchronous Programming Model:

If you want to boost the scalability of the application, the requirement is that the application should adopt an asynchronous programming model.

However, developers find this model to be more difficult as compared to linear blocking I/O programming.

Another disadvantage of the asynchronous programming model is that the code becomes clumsy, and programmers need to depend on the nested calls.

4. Single-threaded nature:

Node.js is single-threaded, meaning it runs on a single thread and can only utilize a single CPU core at a time. This design choice can limit its performance in certain scenarios, especially when dealing with CPU-intensive tasks. Although Node.js uses an event-driven, non-blocking I/O model to handle concurrent requests efficiently, it is not well-suited for CPU-bound operations.

5. Callback-based programming model:

Node.js relies heavily on callback functions to handle asynchronous operations. While callbacks provide a way to manage asynchronous code execution, they can lead to complex and nested code structures, often referred to as “callback hell.” This can make code harder to read, understand, and maintain. Although newer asynchronous patterns like Promises and async/await have been introduced to mitigate this issue, legacy codebases may still heavily rely on callbacks.

6. Memory consumption:

Node.js can consume more memory compared to some other server-side technologies. This is partly due to the need for duplicate instances of shared resources for concurrent requests. While memory consumption can be optimized by careful coding and monitoring, it is an important consideration, especially when deploying applications on resource-constrained environments.

7. Limited support for multi-core scaling:

While Node.js is efficient in handling concurrent I/O-bound operations, it lacks built-in support for scaling across multiple CPU cores. This can be a limitation when developing applications that require high CPU utilization or parallel processing. Although there are workarounds like using the “cluster” module or external tools, managing multi-core scaling can be more challenging compared to platforms explicitly designed for multi-threaded execution.

8. Limited standard library:

Compared to some other programming languages, Node.js has a relatively limited standard library. While it provides essential functionalities for building web servers, networking, and file system operations, many other common functionalities require external libraries. Although the Node Package Manager (NPM) ecosystem is vast and offers numerous third-party packages, relying on external dependencies may introduce security risks, compatibility issues, and maintenance challenges.
