Pros And Cons of Node.js Web App Development In 2022
What is Node.js?
They allow you to quickly and efficiently develop the backend part of applications, which is extremely important in each dev project.
To understand when to use Node js for your project you need to know all pros and cons that come with it. Read on and find out everything about Node js development service to find the most effective solution for your business project.
We gathered top advantages of using Node.js that are worth exploring.
A cut above efficiency and dev productivity
Node.js can process requests without any delays due to non-blocking Input-Output, as well as asynchronous handling. In the backend, synchronous processing supposes that code is done in a sequence, where each request is seen as a thread. In such cases, requests are handled one by one. But asynchronous processing brings no blocking of the threads.
What does it look like?
- A request is processed
- After it can push out a callback
- Continue serving other requests
That results in:
- Making the most out of a single thread
- Short response time
- Simultaneous processing
Another important aspect is that Node.js is the event-based model. With the same language for both client and server sides, synchronization is quick. That’s very beneficial for event-based, real-time apps. This is why Node.js is widely used for:
- Online gaming
- Video conferences
Well, and any solutions that need constant data updates. For example, PayPal saw a 35% decrease in response time after migrating from Java, which is a bright example of why so many leading companies are switching to Node.js apps.
So, if you want to rewrite your backend on Node.js—drop us a line, and we will provide quality solutions for your business.
Stack Language Sharing
Using Node.js makes possible:
- Client and server apps code exchange
- Improving backend and front-end communication and teamwork
Questions and issues are unavoidable in the development process, which makes the strong community of Node.js another great advantage. The bigger the community and the faster it’s growing the higher the chance of finding the answer you need faster. Also, it allows developers to always stay up to date.
Having an active community also facilitates the search for specialists if you need to expand the team. Let us share a real story from OmiSoft experience. One of our clients faced a burning problem of lacking Ruby specialists for the project. We rewrote it on Node.js and the problem disappeared.
Strong support by big corporations
The founding members of Node.js are big organizations like Microsoft, IBM, Fidelity, PayPal, and SAP, and it currently includes 300 popular companies, such as Trello and Uber. Such huge support from the world’s leading companies is rare for open source projects, which is a clear sign of the exceptional potential of Node.js
Native AWS Support
Amazon Web Services (AWS) is a hosting platform ⅓ of developers, as a host is needed for all web apps. Node.js is supported natively in AWS, which means that it’s integrated with it, making it another great advantage. What difference does it make?
- Developers can make changes to the code in their browser with Cloud9.
- Using Node.js is possible also with Amazon’s IoT

Even though using Node js comes with a lot of perks, there are also a few drawbacks that are worth exploring.
Bottlenecks in performance
Probably the main drawback of Node.js is that it can’t process CPU-bound tasks. The Node performs JS code on its single thread on an event basis, processing tasks asynchronously, which creates an event loop.
Node.js has a single thread of execution and does not allow for parallel processing, so it’s not the best choice for CPU- or memory-intensive apps.
As a heavy request comes, Node.js would set all the CPU at hand to process it, and then answer others, which results in slow processing. However, Node.js 12 introduced multithreading, which enables parallel processing on a different thread.
Hell of Callbacks
Because Node.js runs tasks asynchronously, it uses callbacks extensively. Callbacks are functions that run after each task is completed. Keeping a large number of callbacks queued in the background can result in a situation called “Hell of Callbacks”, where callbacks are nested several levels deep, which brings extra complexity and difficulty in understanding and maintaining the code.
But good development helps to get around this problem and usually experienced Node.js specialists can handle them.
Are tools mature enough?
Even though core Node.js modules are stable and are considered mature, some of the tools in the npm registry are not of the best quality or are not yet properly tested. Besides, the registry itself isn’t organized well enough to suggest tools based on their quality or rating.
Therefore it might be a challenge to find the best solution for your needs. And, It’s essential to use tools and libraries that are already stable, actively supported, and developed, and that have already become the standard in the Node.js world.
High demand for experienced Node.js developers
Let’s sum up
So, what is Node.js good for?
|Good for||Not the best option for|
|Data streaming||CPU-Heavy Server-Side Computation|
|Collaborative tools||CRUD apps (related either to Create, Read, Update, Delete)|
|Online gaming apps|
|E-commerce transaction software|
The bottom line
The backend development is a very important part of the product, therefore the quality of implementation is super important, so it is better not to save on backend developers and to validate them well. Is Node.js still a good choice for the backend? — Hard yes!
