NodeJS – Short Glimpse
NodeJS is an open-source, cross-platform JavaScript Runtime Environment that permits tech innovators to execute JavaScript code outside of a web browser. There are a vast number of large enterprises, such as Netflix and Uber, that employ NodeJS – the most popular lightweight web framework for newbies.
JavaScript is often linked to web development in our minds. There were no techniques to execute JavaScript outside of a web browser until NodeJS came along. NodeJS is the finest programming language for encoding backend servers and databases since it enables you to perform the code as a particular application rather than something that can only be tested in a browser ecosystem.
Another app platform normally makes a diverse option than NodeJS. Threads are typically used to scale web and mobile applications to occupy the CPU. Threads are often used to make web and mobile apps handle more tasks at once, but nodejs don’t use them because they can be complex. Instead, NodeJS uses a single-threaded, event-driven system. This process is known for using less memory, being fast, handling tasks well even when busy, and having a simpler programming style.
It is a ​​self-powered JavaScript Engine with extensions that are good for general-purpose programming and concentrate on Application Server Development.
Understanding How NodeJS works?
NodeJS is a popular open-source platform often chosen for developing a back-end process. Working with NodeJS is quite straightforward – it handles client requests and retrieves responses using just one thread. In NodeJS, threads are employed to manage I/O requests and operations.
A thread is like a set of instructions for the server to follow. These threads can execute simultaneously on the server to give data to various clients. NodeJS performs with a single-threaded event loop, allowing it to handle a multitude of tasks or requests without getting blocked by any single one simultaneously.
Node.js operates on the conceptualization of unsynchronized and non-blocking I/O. Let us see how each one works for Node.js functionality.
Key Aspects of NodeJS
NodeJS as Non-Blocking I/O
With Non-Blocking in NodeJS with a multitude of requests without blocking the thread for a single request is referred to as Non-Blocking I/O. Typically, NodeJS does not work with multiple threads because it is a single thread that can’t manage the CPU work. NodeJS is not used for CPU-intensive work such as video processing or calculations.
Asynchronous Type
In NodeJS, “Asynchronous” means that the callback function works in the background. This function gets activated once a response is received from another database or server. NodeJS works on an event-driven system, so callback functions are called right after a task is done. Rather than dealing with the request directly, the single thread passes it to another system, that takes care of it and prepares the result for future requests.
Features included in NodeJS
NodeJS functions on the Chrome V8 JavaScript Engine. The primary function of NodeJS goes as per the events and hence it is known as an event-driven, non-blocking server that makes all types of front-end applications. The architecture is push-based but permits easy slip into the development of all types of applications. Here are some of the salient features of NodeJS:
- It operates asnchronously or non-blocking, especially in a microservices architecture.
- It is a more consistent and cleaner source code.
- It is simple for JavaScript programmers to use NodeJS to create Backend services.
- It is Open-source Libraries and a large environment.
- It is simple to use and can execute best for prototyping as well as agile methodologies.
- It provides services that are both quick and scalable.
- It executes in a single-threaded nature and is still faster in the development process.
- It creates SASS, Desktop Platform, and Services at the same time.
Benefits of NodeJS

Flexible Scaling for Developers
NodeJS permits developers to scale their real-time applications both horizontally and vertically. This indicates you to add more resources as your application evolves.
Great for Web application
Whether you are using PHP or NodeJS, developing a web app takes about the same time. However, when it comes to developing chat or game applications, NodeJS is preferred because of its faster synchronization.
Complete Functionality
NodeJS works on the innovative Google V8 engine. It uses an event loop to manage asynchronous actions swiftly. This includes tasks like writing and reading to databases, network connections, and file system access.
Easy to learn and code
NodeJS uses JavaScript, which makes it easy to learn and code. if you are a front-end developer with a good understanding of JavaScript, you can grasp it instantly and create applications using NodeJS
Caching Benefits
It permits you to cache a single module. The first time a module is requested, it is stored in the application memory, which eradicates the necessity to re-execute the code.
Streaming Data
In NodeJS, HTTP requests and responses are like separate streams of data. This speeds up file processing during loading and lets data flow as it comes in. You can also play audio and video really fast using this.
V8 Engine
It uses a V8 engine from Google. It alters JavaScript code into machine code for instant execution, which makes things happen quickly. The single-threaded event loop in NodeJS manages n number of tasks without using a lot of resources.
Long-term Support
NodeJS versions get support for 18 months after they are marked as stable. During this time, they fix errors and ensure everything is secure, which provides stability for projects.
Type of Applications Can We Develop with Node JS
