How Node.js Works?

Node.js is basically a runtime environment that allows JavaScript to run on the server side. It is built on the latest version of the JavaScript engine from Chrome, which compiles JavaScript into machine-readable code. Node.js operates on a single-threaded system using an event loop that handles many concurrent processes without blocking.

When a client sends a request to the Node.js server, the request is placed in an event queue. The event loop constantly checks the queue and processes each request. If the request involves an I/O process, Node.js offloads it to the system’s kernel, which manages it asynchronously. 

Once the I/O process is complete, the kernel notifies Node.js, which then executes the corresponding callback function. This event-driven, non-blocking system enables Node.js to handle multiple concurrent connections efficiently, making it perfect for developing large-scale, high-performance networks.

Features Of Node JS App Development

We will now discuss some of the key capabilities of Node JS development:

Event-Driven and Non-Blocking Nature

Servers created with Node.js do not wait for API data to be received. If there is no need to wait for information from the API, Node.js immediately moves on to another API. Thus, all APIs in Node.js are non-blocking in the sense that they do not block execution. To handle and monitor results from earlier API requests, Node.js uses an event-driven mechanism. Therefore, we can conclude that Node.js APIs are non-blocking as they don’t halt other operations.

Single-Threaded Architecture

Node.js utilizes a single-threaded event loop architecture, which makes it more adaptable. In contrast to other servers, Node.js only creates a few threads to process requests. The event-driven system allows Node.js to respond in a non-blocking or asynchronous manner, which is why it is more efficient in terms of scalability. 

When compared to traditional servers, such as Apache HTTP servers, Node.js can handle a larger number of requests. A single-threaded model, combined with Node.js, allows it to process a massive number of requests efficiently.

Scalable

Scalability is a crucial requirement for most businesses today, and Node.js addresses this challenge effectively. It can handle concurrent requests with ease. Node.js uses cluster modules to balance the load across all active CPU cores. One of the most attractive features of Node.js is its ability to horizontally scale applications. This is done by partitioning tasks through child processes. This approach allows various versions of apps to target different user groups, catering to client-specific needs.

Quick Execution Time For Code

Node JS app development uses the V8 JavaScript runtime engine, the same engine used by Google Chrome. This engine enhances JavaScript’s performance, making it faster. In Node.js, request handling and code execution are quicker due to this optimization.

Uses JavaScript

From a developer’s perspective, one of the most significant features of Node.js is its use of JavaScript. Since many programmers are already familiar with JavaScript, it becomes easier for them to adopt and work with Node.js.
