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?
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.
- It runs in a single thread with a callback concept.
Advantages of NodeJS
Here are the advantages of using Nodejs as server-side programming:
1. Easy to learn:
2. Supported widely by Google Chrome:
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 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.
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:

6. Single Programming Language:
7. Large and Active Community:

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
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 in 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:
As a result, users are force 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.

Node.js is a quick, lightweight, and efficient programming language. It employs an asynchronous method of operation, event-driven Input or Output, rather than typical or distinct threads for each activity. There are several advantages and disadvantages of Node.js, however, it occupies a prominent role in full stack development. Let’s explore why Node.js could be the best choice for you.
Another advantage of adopting Node.js is that it includes built-in JSON support. While the majority of backend languages require additional libraries to read JSON, Node.js handles it uniquely.
The evergreen NPM
These packages were created by the fantastic community and will address practically all general Node.js issues. To speed up and streamline the development process, we employ NPM packages in our products. As a result, you won’t have to code from the scratch. The world’s largest application library registry is found in Node.js.
By installing not only the library’s code but also all of its dependencies, NPM helps manage application dependencies simply.
AWS native assistance
All online applications require a host, and with 32% of the cloud market, Amazon Web Services (AWS) is perhaps the most widely used hosting platform available. AWS has strong platform integration and native support for Node.js.
The user may create and edit code straight from their browser using Cloud9, the in-browser Integrated Development Environment (IDE) from Amazon. This is one of the most accessible entry points for a scalable microservice, and it works with Node.js.
Development may be started quickly thanks to Node.js. It is a great option for developers building microservice environments because it connects numerous APIs. Node.js is a great option for prototype solutions and architectures since it facilitates quick and easy experimentation.
As you progress through the development process, you may alternate between static or dynamic typing as necessary, providing you flexibility over the layout of the various system components.
When Should You Use Node.js?
To get the greatest application performance, let’s figure out when to utilize Node.js and what it’s used for in web development.
Real-time communication or chatting is one of the Node.js use cases discussed in the textbook since we have discovered that it can provide excellent speed and performance. When alerts are shown to many people at once, the environment can accommodate a high volume of brief messages or chat rooms.
The processing of real-time flows is another aspect of this Node.js use prime example. Software development firms use the project management tool Trello very much. As a result of Node.js’ event-driven, non-blocking approach, Trello was created on its foundation. It works well for programs that need instantaneous changes, including different collaboration programs and online documenting suites.
For executing IoT programming projects, Node.js is the finest option. Node.js is first of all quick, strong, and able to handle enormous data flows. The ability to connect Node.js with the IoT protocols is the second benefit. The NPM also contains numerous useful IoT modules that support the implementation of even the most complex IoT projects.
Video streaming apps
When you transfer a lot of data in “streams,” you do so as opposed to sending it all at once. For applications that stream audio or video, this capability is very important. With built-in modules that allow data streaming and enable the creation of both reading and writing data streams, Node.js is particularly well suited for this purpose. You could get a sense of how potent this environment is if we mention that Node.js is used by Netflix, a major worldwide video service provider.
With the progress of time, more and more business is adopting Node.js and has ended up getting positive results for their business. If you also want to develop an application using NodeJS, you can consult us to hire senior NodeJS developers in India.
