4. Increased agility

Full-stack development enables organizations to be more agile in their development processes. The reason is developers can work on a wide range of tasks, such as creating the user interface and implementing server-side logic.

It is clear why full-stack development has become an essential skill in modern web development. After all, it enables organizations to build robust applications while ensuring a faster development process.

You have enough knowledge about full-stack development. It’s now time to progress to the following section.

An overview of Node.js

Node.js is an open-source JavaScript runtime environment. Its primary purpose is to execute JavaScript code outside of a web browser. Developers use this technology to build server-side applications with JavaScript. In addition, it is a crucial part of full-stack development.

Over the past few years, Node.Js development agencies have been helping enterprises to create robust applications. Courtesy of its incredible features, Node.Js has become one of the essential elements of tech stacks like MEAN, MERN, or MEVN. Listed below are several of its key features.

What are the primary features of Node.Js?

Node.js offers several features that make it a well-suited platform for building server-side applications. These help you learn the working of Node.Js. That also made it a vital component of full-stack development. It boasts several key features, including

* Event-Driven Architecture

Node.js uses an event-driven architecture. That implies it can handle numerous events or incoming requests simultaneously. Thus, full-stack developers can craft applications that are scalable, and high-performance while managing a lot of traffic.

* Asynchronous Programming Model

Node.js depends on an asynchronous programming model. Again, it helps in handling multiple requests at the same time. It does not involve waiting for one request to finish before starting the next. So, this feature ensures better performance and scalability of applications. It is a boon for applications dealing with I/O-bound or high-traffic operations.

* Single-Threaded Model

Despite its ability to address multiple requests, Node.js uses a single-threaded model. What does it mean? It uses one core of a computer’s processor, which helps to reduce the overhead of managing multiple threads. It will lead to overall improved performance and scalability.

* Non-Blocking I/O

 Another feature is the non-blocking I/O model. Thanks to this, it does not block incoming requests while performing I/O operations, such as reading from or writing to a database.

* Large Ecosystem

Node.js has a large and active community of developers who have created a vast collection of packages and modules that can be used to perform various tasks, making it easier to build complex, full-stack applications.

All these features contribute to creating high-performing and scalable. Now, you know why most businesses (small or large) hire Node.Js development companies in the USA. But how does each feature help in Node.Js operation? If you are curious to know, scroll below.

How does Node.Js work?

Node.js relies on an event-driven, non-blocking I/O model. That means when a request is made to a Node.js server, it adds the request to an event queue and continues processing others. It does not block the server. Thus, it prevents the client from waiting for a response. Once processed, a callback function is executed, and the server sends a response to the client.

Node.js relies on the V8 JavaScript engine developed by Google to execute JavaScript code on the server. The V8 engine compiles JavaScript code into machine code, making it faster and more efficient than interpreting the code in real time. It is a little surprise Node.Js development agencies surged in demand.

In addition, Node.js includes several built-in modules, such as the HTTP module. It enables full-stack developers to create and manage HTTP servers with ease. They can also install and use third-party modules from the npm repository. These are crucial to expanding the functionality of a Node.js application.

In short, when a client makes a request to a Node.js server, it uses the HTTP module to process the request, read the requested data, and perform any necessary calculations. After this, the server sends a response back to the client. The process is repeated for each request, allowing the server to handle multiple requests simultaneously. As a result, it improves the performance and scalability of the application.

That is why most enterprises rely on Node.Js development agencies for their back end. But how does it makes an impact on full-stack development? We will find out here.

The role of Node.Js in full-stack development

Firstly, Node.Js uses JavaScript. What does it mean to full-stack developers? They need to learn one language for both the front-end and back-end of their application. That makes the development process more efficient and streamlined.

2. Built-in packages and modules

Since Node.js has a vast library of modules and packages (Node Package Manager), developers can add functionality and features to an application. It is one of the reasons Node.Js development agencies gained popularity in a short span.

Another excellent Node.Js feature is the built-in HTTP module. As we mentioned, it makes it easier for programmers to create web servers and handle HTTP requests. It also has a large, active community of developers who have created a collection of packages and modules. With this, full-stack developers can perform various tasks, such as connecting to databases, handling security, and processing data. These packages can be easily installed and used in a Node.js application. Hence, developers can build complex full-stack applications.

3. Scalability

Node.js is popular for developing real-time, data-intensive applications such as chat apps and online games. What makes it a good choice for these types of applications? The answer is an event-driven, non-blocking I/O model. It is capable of concurrently processing multiple requests without the need for waiting for responses. Consequently, it improves the performance and scalability of the application.
