With time, however, Node.js has moved beyond “web development” and into areas such as API development and mobile app development.
Even after all this time, there is still a widespread misconception regarding Node.js; that it is a framework.
But the fact is, that Node.js is a runtime environment based on the V8 engine from Google Chrome.
Node.js has come to prominence at an incredible rate, and the reason for this is because, similar to how Angular filled the void of client-side scripting, Node.js filled the void of server-side scripting, and even featured capabilities that could help connect the client and server-sides.

What is Node.js?
As Node.js is open source, it is free to use and is continually being updated and improved by a global community of developers.
Node.js allows developers to create fast, scalable network applications with simple code. It’s compatible with Windows, Mac OS X, Linux, Unix, and other operating systems.
What is Node.js used for?
Node.js is used in many different applications. Let’s look at some common scenarios where Node.js is a good fit:
- Real-time Chats: Node.js is well-suited to handling real-time communication due to its single-threaded asynchronous nature. It’s scalable and frequently used in chatbot development. Additional chat features like multi-person chat and push alerts are similarly simple to implement with Node.js.
- Internet of Things: IoT applications commonly use numerous sensors, as they often send small pieces of data that can accumulate into a huge number of requests. Node.js is a fantastic choice because it can handle these concurrent requests rapidly.
- Data Streaming: Netflix and other streaming services use Node.js. This is mainly because Node.js is lightweight and fast and also provides a native streaming API. Users can pipe requests to each other over these streams, resulting in data being streamed directly to its final destination.
- Complex Single Page Apps: The entire app is loaded on a single page in SPAs. This usually signifies that a few requests for certain components are being made in the background. The event loop in Node.js comes to the rescue here, processing requests in a non-blocking manner.
However, there are various other reasons why you should use Node.js:
- Developers can easily deploy Node.js apps using Node.js web hosts
- It is popular for creating real-time apps
- Node.js has good community support
- Node.js has many frameworks like Express.js, Koa, Nest.js, etc.
- It’s great for startups since it allows them to develop their products faster and enter the market sooner.
What Does Node.js Do?
Node.js uses are not limited to only web apps but also include microcontrollers, REST APIs, static file servers, OS wrappers, robots, and even drone programming. Rather than a listless request-reply message exchange pattern, the technology uses a progressive event-driven paradigm, which creates an event loop that is ready to react to an occurrence.
In a simple way,
- Node.js dynamically generates page content.
- On the server machine, Node.js generates, opens, reads writes, deletes, and closes files.
- Node.js also collects form data.
- Node.js updates databases by adding, deleting, and modifying data.
- Node.js can be used smoothly by both backend and frontend developers.
- Node.js makes it easier to create high-traffic, real-time apps like gaming and chats.
- Compared to other languages, Node.js code execution is faster.
- The rapidly expanding Node Package Manager (NPM) provides developers with a variety of modules and tools to help them work more efficiently.
The ability to highly modify the response based on the user’s requirements, access rights, or queries into data storage is the fundamental benefit of server-side scripting.
While working with the request, Node.js accepts requests from clients and sends responses. They are handled by a single thread in node.js. Threads are used by Node.js to handle I/O operations and requests. A thread is a set of instructions for the server to execute. It runs in parallel on the server to provide data to several clients. Node.js is an event loop single-threaded language. With a single thread, it can handle multiple requests without blocking it for one.
Node.js is based on two concepts.
- Non-blocking I/O
Netflix, Paypal, Uber, etc are some of the big giants that have implemented Node.js and have grown considerably in size. Given its popularity among software developers, it is realistic to assume that Node.js will continue to expand at a similar rate in the future.
- It is easy to learn
- Highly scalable
- Node.js is light and fast
- Cross-platform development
- Active community
Since its introduction in 2009, Node.js has risen to become one of the most demanded technologies, indicating that it is extremely powerful. Node.js has become a solution to many difficulties by providing security, scalability, and performance.
