Advantages And Disadvantages Of Node.js : Pros and Cons

Node.js is considered as the first preference for web app development.

But the main question is why?

If you are also trying to find the answer of this query then keep reading ahead. Because in this blog we are going to describe what is node.js and what are its pros and cons?

What is Node.js?

It is the environment developed upon JavaScript runtime for creating quicker and scalable network apps.

Node.js provides developers event driven I/O APIs and asynchronous. With the help of Google’s V8 JavaScript engine it is also capable of interepting JavaScript code.

Whether you talk about node.js web applications, hybrid applications, Rest APIs, IoT solutions, desktop programs. On Node.js you can develop all these types of apps.

Do you want to learn more about Node.js?

Let’s dive into the pros and cons of Node.js and try to understand it in details.

Pros of Node.js

  • Learning it is not difficult

It is the universal truth that JavaScript is among the go-though programming language and front developers in large has really good grasp over it. Using Node.js at the backend becomes much easier for developers. It takes a less time to understand Node.js

  • Scalability

The greatest benefit of Node.js is that in both horizontal and vertical orientations developers can grow the applications. Also, by adding additional nodes to the existing system apps can be horizontally scaled.

It also allows you to include additional resources to single nodes during the vertical scaling of the application. Thus, it is tremendously scalable and provides a best substitute to existing JavaScript servers.

  • Minimizing load time by quick caching

Node.js has caching module that makes it easier for developers to minimize the workload and code re-execution.

Hence, developers don’t need to re-execute the code because caching enables apps to load the web pages quicker and swiftly respond to the users.


  • Unstable API

It is the major drawback of Node.js that faced by developers is application programming interface keep changing frequently and its not reliable.

There are times when suddenly new API pop-ups with numerous backwards-incompatible changes.

Ultimately, in order to match the compatibility with the latest version of Node.js API, developers are compelled to make changes in the accessible code bases.

  • Library support system is weak

In comparison to other languages JavaScript lacks in robust and well-equipped library support. Ultimately it leaves user with no option other than to take support from the common available library for implementing tasks like XML Parsing, operations, Relational mapping etc.

Making really challenging for developers to execute common programming tasks by using Node.js

  • Asynchronous programming model

Increase the scalability of app by adopting the asynchronous programming strategy. But at times many programmers considered this programming method more challenging than linear blocking and I/O programming.

Code tends to become clunky leaving programmers no option other than depend upon nested calls.
