Why Use Node.js? Advantage & Disadvantages of Node.js

So, you are looking to develop a web app for your business, right? Well, that’s the reason you’re here, looking to expand your knowledge about the advantages and disadvantages of Node.js and how it could be beneficial.

Node.js is an open-source JavaScript runtime environment for developing real-time network applications based on Chrome’s V8 engine. It is event-driven and has non-blocking I/O, making it ideal for designing lightweight and quick web programs.

Walmart, Medium, Netflix, and LinkedIn are just a few successful organizations that have used Node.js to build their apps. Also, the Node.js framework has become a preferred choice for many industries like IT, Healthcare, and many more. But now the question arises- Why Should You Choose Node.js?

Well, in this post, we’ll be discussing the potential advantages and disadvantages that you should consider before you make a choice.

Advantages of Node.js

1. Google Chrome has Immense Support

Node.js powers the search engine, and it not only helps with front-end development but also has a significant impact on the backend. The Google V8 engine supports Nodejs and provides the ability to run many JavaScript scripts in the frontend simultaneously.

Google lists Node.js as one of the quickest runtime system engines, which is incredible. It’s also simple to detect errors in both the front end and the backend with Nodejs.

2. Scalability is Simple

When it comes down to designing responsive web apps, Node.js has been a preferred choice. A cluster module in the cross-platform runtime environment helps load balancing. Node.js also has a non-blocking event loop architecture, which allows servers to run without interruption.

Node.js is an excellent framework for developing modern applications that can scale up and down as needed. It also enhances the overall performance of online apps while consuming fewer resources.

3. Affordability Comes with Full-Stack JS

One of the most significant benefits of Node.js is that it allows programmers to develop server-side JavaScript code and front-end JavaScript code with simplicity. In addition, one of the significant node.js advantages is that it eliminates the need for two resource teams, saving a substantial amount of time, money, and energy for overall project development.

4. Simultaneous Request Handling

Node.js has a non-blocking IO architecture that allows you to process several requests at the same time. Simultaneous request handling is significantly better in this system than in other languages like Python or Ruby. Incoming requests are queued and executed rapidly and efficiently. As a result, your software will use significantly less system RAM, achieve high levels of scalability, and run much faster.

5. Improve App Performance

With its single-threaded event-loop paradigm, Node.js provides a non-blocking asynchronous architecture while using fewer resources and producing fewer threads. This improves the responsiveness of your program by allowing it to handle several concurrent users.

Disadvantages of Node.js

1. Changes Take Place Frequently

The frequent API changes, which are often backward-incompatible that drive Node.js users up the wall, are among the most primary complaints mentioned by Node.js users. Unfortunately, this forces them to alter the access code regularly to keep up with the latest version of the Node.js API.

2. API is Unreliable

One of the most common issues developers confront while working with Node.js is that the Application Programming Interface (API) changes frequently and does not remain stable.

Occasionally, a new API will be released with several backward-incompatible changes. Consequently, developers must make changes to the available codebases to stay current with the latest version of the Node.js API.

3. Uneasy to Maintain Code

Due to the obvious asynchronous approach’s essential nature, the technology replies to callbacks a lot. Moreover, this method runs soon after each job in the queue, ensuring multiple queued tasks operate in the background.

Callback hell is a term used to describe the possibility of a callback. It has a direct impact on the code’s performance and quality. The code is practically boring to comprehend and maintain because of this constraint.

4. Not Suitable for Heavy-Computing Apps

This is one of the biggest disadvantages of Node.js! It does not currently support Multi-threaded programming. It can handle far more complex applications than Ruby, but it isn’t designed to handle long-running calculations. Heavy computations can cause a performance drop. So while Node.js is ideal for complicated programs, it may struggle with software that requires a lot of processing power.

5. Lack of Library Support Can Jeopardize Your Code

Some NPM registries and libraries are either of poor quality or are unfinished and poorly described. As a result, if some amateurs create a web application in Node.js, monitoring will be impossible.

Only well-qualified and trustworthy individuals with project experience can ensure your project’s success. In addition, because it is open-source and has many libraries and modules, there may be a lack of solid coding standards.

The Bottom Line

So, that’s a wrap to the Node.js advantages and disadvantages for developers! Node.js has far more advantages than disadvantages for developers. It has also broadened the scope of JavaScript applications, making it suitable for both frontend and backend servers.
