Web App Development with Node.js Benefits and Drawbacks

Companies must cover all elements of app development in order to flourish in today’s business environment. You can’t afford to be complacent in today’s environment because the competition is so fierce.

To create a fantastic product, you now need powerful and efficient technologies to back it up. Over the years, JavaScript has remained one of the most popular client-side programming languages. JavaScript has evolved into a key cross-platform app development tool, as well as being utilized in web frontend development.

However, you are mistaken if you believe that the use of JavaScript ends here. It has recently been combined with Node.js, resulting in a paradigm change in online development.

Node.js now has a huge and diverse set of benefits. But first, we must grasp the framework’s fundamentals, after which we can move forward.

So, let’s get started!

What exactly is Node.js?

Node.js is a server-side runtime environment that allows you to execute JavaScript. It was first published in 2009 and has had a major impact since then. The amount of interest in the runtime environment peaked in 2017 and has been high ever since. The fact that market leaders like Walmart, Netflix, and others use Node.js demonstrates its value.

One of the main reasons for Node.js’s success is that it facilitates the creation of real-time network applications. Furthermore, because it is open-source, it is easily available. The event-driven I/O APIs are available to Node.js developers. Through Google’s JavaScript V8 engine, the cross-platform app development runtime environment can also run JavaScript code.

Node.js’s Benefits

Node.js was quickly recognized as an intriguing JavaScript software after its release. As a result, we’ve compiled a list of some of the most important Node.js advantages for the benefit of our readers.

Scalability is simple.

When it comes to designing scalable apps, Node.js has been viewed as a viable option. A clustering module in the cross-platform runtime environment helps load balancing. Furthermore, Node.js provides a non-blocking event loop architecture that allows servers to operate without interruption.

Node.js is the ideal platform for building modern programs that scale up and down as needed. Furthermore, it improves the overall performance of online applications while using fewer resources.

Node.js allows you to add extra resources to single nodes while vertically growing your web application. These additional resources are solely added to the current system.

1. improved performance

Node.js has a strong developer community because it is open-source. The community is vibrant and ever-evolving, and everyone contributes to its growth and improvement. Indeed, one of Node.js’ benefits is that developers can always count on the help of JavaScript programmers. In GitHub, they supply simple solutions and ready-made answers.

It is easier for the developers to solve even the most complex challenges because they have widespread community support. NPM, the largest package manager that offers several tools for online development, is also included in JavaScript. Furthermore, Node.js engineers are supported by industry titans such as Netflix, Google, Amazon and etc.

Because of the tech giants’ embrace, technology has advanced and has a bright future ahead of it.

The above-mentioned IT giants are only a few of the companies that use Node.js. PayPal, Uber, Zendesk, Trello, Medium, Microsoft, and other market leaders use Node.js widely.

2. Full-stack JavaScript is cost-effective.

Developers may write code in both the frontend and backend with ease using Node.js. This is due to the fact that it allows developers to create server-side code in JavaScript. As a result, the organization does not need to recruit two resource teams, lowering the overall development cost.

Aside from that, it speeds up the entire web development process without sacrificing quality. You won’t need to recruit separate frontend and backend developers if you use Node.js with full-stack JS. As a result, even small businesses can benefit from Node.js.

Exceptional Tech Stack

One of the key reasons why Node.js has become a household brand around the world is because of its solid technology stack. When you utilize Node.js for the backend, you receive all of the benefits of full-stack JavaScript development right now.

The following are some of the most significant Node.js benefits:

  • High speed and performance
  • Overall production and efficiency have improved.
  • Developers have a plethora of free tools to select from.
  • Sharing and reusing code is a feature.
  • Within the team, communication and knowledge sharing are simple.
  • Apart from the benefits listed above, Node.js allows the entire development team to be more adaptable. As a result, your program will be speedier and more reliable. Furthermore, by wrapping the frontend and backend into modules, code reuse aids in the creation of new levels of abstraction.

3. Handling many requests at once

Thousands of concurrent requests are easier for Node.js to handle. Node.js is widely utilized in complicated and large web applications with a significant number of visitors because of this benefit. Furthermore, in Node.js, there is a low cost on a single process while handling requests.

4. Time to load is reduced.

The caching module in Node.js reduces the overall loading time, which is one of the main advantages. As a result, the engineers may take a deep breath and focus on their tasks.

The advantages of using a caching module are numerous. When the initial module of the web app receives a request, for example, it is immediately cached in the in-app memory. As a result, the user can view online sites in a matter of microseconds without having to wait long.

5. Overall performance of the app has improved.

It has an impact on the performance of a sophisticated program that has to cope with multiple to and fro requests. Furthermore, because the modern world is so competitive, you can’t have an application that can’t manage a lot of requests.

In this case, the advantages of Node.js can help enterprises achieve excellent results. The single-threaded event-loop approach of Node.js allows for non-blocking asynchronous design. There is no need to expend extra resources to create more threads because of the architecture.

The responding time improves when there are fewer threads. As a result, the programs may handle several requests at the same time.

Allows developers to be more creative.

One of the most significant advantages of Node.js is that it provides developers with complete development independence. Unlike Ruby on Rails, Node.js does not have a set of rules to follow. As a result, the developers are free to start anything fresh while still working on the software.

Node.js has some drawbacks.

After learning about Node.js’s high-flying benefits, it’s also vital to learn about its drawbacks. The downsides of Node.js are listed below.

  • Inability to do CPU-intensive jobs
    One of the most significant drawbacks of Node.js is its inability to do complex computations. Node.js has the ability to run JavaScript code in a single thread. The issue arises when Node.js is asked to do a CPU-intensive activity.

    When a large request comes in, for example, Node.js will process it first and then respond to the smaller requests. As a result, the entire processing system slows down, resulting in a delay in the event loop. This is why Node.js is not recommended for high-performance computing.
  • Tools of poor quality
    Node.js modules are fairly reliable and mature. However, the NPM repository contains a large number of low-quality utilities. Furthermore, the NPM registry is not well-organized to provide tools depending on their quality and ranking.

    The open-source nature of Node.js plays a significant part in determining the tool’s quality. On the one hand, contributors such as Joyent keep a careful eye on the quality of the Node.js technology. Now, in terms of the remainder of the tools, there’s a good probability that they’ll be of poor quality.
  • API that is unstable
    Another significant drawback of Node.js is that it undergoes frequent API updates that are incompatible with previous versions. As a result of their incompatibility, their instability now necessitates extensive code adjustments. Furthermore, as a result of the lack of competent Node.js engineers, continuous code changes are required to keep up with the latest version.

    Every year, the potential demand for Node.js engineers grows, yet there aren’t enough experienced developers to meet it. Furthermore, companies must recognize that not all JavaScript developers are also Node.js developers. Because mastering JavaScript necessitates an understanding of backend programming, developers must be familiar with it.As a result, despite the fact that there are millions of JavaScript engineers, finding a skilled Node.js developer is difficult. That is why companies are opting to outsource their Node.js development projects these days.


It seems evident that the advantages of Node.js outweigh the cons. Furthermore, organizations must establish their requirements in addition to recognizing the benefits and drawbacks of Node.js. In order to reap the full benefits of Node.js, it’s also required to contact a reputable Node.js development firm.

Node.js is also used for both frontend and backend servers because it includes JavaScript. Node.js provides everything you need to drive your company to new heights, but it must be used properly.
