For web developers, Node.js is so what of a blessing. If you are new to web development and are not aware of what are the key features of Node.js or don’t know why so many developers are opting for Node.js, then don’t worry because we got you covered, my fellow coder! In today’s article, we are going to discuss what is Node.js and the features which make it so much in demand right now! Let us start?
What is Node.js?
As time passes, technology evolves tremendously and so does web development. Node.js is one of the best technology a developer can use as it mainly collects the data from the client and then the data is added, deleted, or updated as per the requirements. Once the particular task is done, Node.js sends a response back to the client. All this happens in a matter of seconds, this is the reason why so many developers are learning about Node.js.
Key Features of Node.js
Now that you have an overview of what Node.js is and why it is constantly gaining popularity, let us discuss the main features of Node.js:
- Asynchronous Nature
- Event-Driven Architecture
- Single-Threaded Working
- Multiple platform compatibility
- Quick Data Streaming
- Minimum Buffering
Let us now understand these features of Node.js in depth.

2. Asynchronous Nature
One of the most important features of Node.js is its asynchronous nature. The term asynchronous means that a server that is built using Node.js never needs to wait for the date from an API. With this, it also has a non-blocking I/O which refers to the code not blocking the running of any further operation. Asynchronous and Non-blocking go hand in hand. Both of them make Node.js have a fast response time and provide a better user experience.
3. Event-Driven Architecture
The term event-driven means that once a task is completed something will happen. In Node.js, once an event is triggered or completed, a callback function also known as the event handler gets executed. Callback functions require fewer resources on the server side and also take up less memory. Due to this feature of Node JS, the application is lightweight.
4. Single-Threaded Working
In Node.js all the requests are single-threads and are collected in the event loop. This means all the programs are executed in the same thread, from receiving the request to completing the required task to sending the response to the client back. This feature of Node.js prevents reloading and reduces content switching time making it more economic to use.
The majority of the companies want applications that are highly scalable and robust. Node.js can handle concurrent requests effectively while balancing all active CPU cores. This feature of Node.js makes it very favorable for developers to use. Furthermore, the different versions of Node.js cater to the various aspect of the client hence making with highly customizable.
6. Multiple platform compatibility
As we discussed previously, Node.js can be used on a wide range of systems, from Windows to Mac OS to Linux and even for mobile platforms. With the correct package, it gives a self-reliant environment.
7. Quick Data Streaming
8. Zero Buffering
Node.js works with data streams that are chucked data and due to this there is no or zero buffering of data when Node.js is used.
