Origin of Node.js

Node.js: A Young Framework That Revolutionized Software Development - A Look at Its Origin, Benefits, and Popularity.

Node.js, a framework that has left an indelible mark on the software development industry, is just 12 years old. In comparison, JavaScript is 24 years old, and the internet itself is 32 years old. Despite its relative youth, Node.js has proven to be a powerful tool.

In 2009, Ryan Dahl wrote the first code for Node.js, which initially only worked on Mac OS X and Linux. What inspired him to develop Node.js? The V8 engine. The team behind the Chrome browser had created their own JavaScript engine, the V8 engine, which could directly convert raw code into machine code. This capability made JavaScript faster and more agile in web browsers.

Ryan saw an opportunity to use JavaScript for developing mobile applications, desktop applications, and servers. The business model of Netscape, where Node.js was created, included trading web servers. Netscape LiveWire, a program that allowed users to build dynamic pages using server-side JavaScript, was part of the package. Unfortunately, Netscape LiveWire failed, and server-side JavaScript didn't gain traction until Node.js came along.

Node.js was built in the right place at the right time, but its current popularity is due to more than just timing. It introduced new ideas and methodologies for server-side JavaScript development, and its engine, V8, improved greatly due to competition.

According to a 2022 survey by Stack Overflow, Node.js is the favorite technology of 47.12% of developers, making it the most popular framework among those surveyed. It's no surprise, as Node.js has become a reliable and powerful tool for building modern applications.

How Node.js Works?

Node.js, which started as a small idea, has grown into a widely popular open-source web framework with an MIT license, a large community, and numerous crucial add-ons. Despite the plethora of viable technologies available, the majority of the software development community has chosen to learn Node.js for web development.

If you're searching for skilled developers to build your next application using Node.js, consider hiring dedicated developers. To understand how Node.js works, let's consider a simple example.

Imagine that you visit McDonald's to order your favorite meal combo. You place your order, and it's delivered immediately. However, the McDonald's floor becomes crowded with a group that has arrived for a birthday celebration. As there is only one person managing the orders, things become chaotic. If you place another order, you have to wait until the other orders are delivered.

This issue could be easily resolved by hiring more staff to take and manage food orders, leading to more orders being served at once. Similarly, Node.js is an event-driven system, and the server comprises a single thread that processes one event after another. Think of every new thread as a new employee who manages the order, while browsers represent the hungry birthday party group who want to order food.

Node.js uses a dedicated thread for each new request, which allows the server to continue processing requests while waiting for a blocking IO operation to complete. Rather than waiting for the operation to finish, the server moves on to the next event and registers a callback function to process the IO action when it is completed. This approach eliminates the need for launching new threads or switching between them, resulting in minimal overhead.

This architecture is particularly useful for CPU-intensive applications because each new request is handled by a separate thread, which frees up the main thread to perform complex calculations more quickly. By distributing the workload across multiple threads, Node.js can process requests more efficiently and achieve better performance.
 

Event Loop

The event loop is a program that waits for events to occur and dispatches them when they do, and it's important to remember that both JavaScript and Node operate on a single thread. Think back to the McDonald's example: no matter how many people are waiting in line, only one employee is serving food in Node.

Unlike other programming languages, which create a new thread or process for each request, Node.js accepts all requests and delegates most of the work to other system workers. The 'Libuv' library, with the help of the OS kernel, handles this. When background workers complete their tasks, they send events that are registered with Node.js callbacks.

Callbacks

Callbacks are functions that are passed as parameters to other functions and are invoked when specific conditions are met. Node.js developers often create event handlers that are triggered by specific Node events. Although Node.js operates on a single thread, it is a highly efficient multithreaded system because most programs are not solely composed of time-consuming numeric, arithmetic, and logic tasks. Instead, they frequently write to the file system, send network requests, or communicate with external devices like a console or peripheral. In these instances, Node.js is excellent at delegating tasks to other threads and handling incoming requests intelligently.

Now let's get to the main part of the post.

When Should You Use Node.js Development?

The short answer is that if you want to create a real-time web application, Node.js is the perfect choice.
