Node.js: Understand Why and When To Use It

With JavaScript gaining the grounds for all the obvious reasons, the technologies likeNode.js are also making their ways to our lives. Node.js is the hottest new technology that helps webmasters develop fast and scalable network applications.

It’s an open-source, cross-platform runtime environment that helps you stay agile while playing around server-side and networking applications.

Node.js makes use of event-driven architecture, and a non-blocking I/O paradigm, which further add to its efficiency and robustness. It’s lightweight structure makes it a perfect choice for developing data-intensive real time applications, that run across distributed devices.

Also, it’s worth noticing that while working with Node.js it’s quite possible for developers to come up with real websites accompanied by push capabilities.


To sum it up in a single sentence:

 Node.js is a leader of creating real-time, two-way connections.

Using a structure like this, both the client and server can smoothly initiate communication, allowing them to exchange data in the manner most effective. This is completely contrary to what we get from a typical web response model, where only client initiates communication.

With all the benefits Node.js has to offer, the system plays a crucial role in building data driven applications.

In this post, I’ll discuss about the advantages you can leverage by using Node.js and why you should consider using this.

Why You Should Be Using Node.js

As discussed earlier, the primary purpose of Node.js is to help developers building data-intensive applications that run flawlessly across distributed devices.

The area where Node.js shines is the way it gives confidence to developers when it comes to building dynamic, and scalable network applications. It’s capabilities of managing and handling multiple connections with extensive throughput is what adds to its performance and scalability.

Node is fast – that’s a major requirement when you are on your way of building next big thing while ensuring you scale it properly with the influx of users as your website grows.

Further, Node is also a one stop solution for offering a Restful API. A Restful API is basically a web service which considers certain parameters and manipulates the data without going through a huge amount of computation. Node has the ability to handle plethora of these where PHP simply gets failed.

Node.js is a JavaScript runtime, which uses V8 engine developed by Google to be used in their Chrome web browser. Leveraging the benefits provided by V8, JavaScript projects can be executed at lightning speed. This speed increase can be credited with the V8 compilation of JavaScript into the native machine code.

Not only this, the real gem behind Node.js is the event loop. The event loop is a single thread which is responsible of performing all I/O related functions asynchronously.

Before the advent of event loop, I/O operations either had to run via blocking or asynchronously by producing parallel threads to go about the work.

The major disadvantage associated with this approach is that it used to consume a lot of memory space and it’s quite daunting to deal with. On the contrary, Node.js passes an asynchronous task to the event loop, accompanied by a call back function, after this it starts executing the remaining tasks.

As soon as asynchronous operation comes to its end, the event loop returns to the task so that its callback could be executed.

Areas Where Node.js Can Be Used

1. Chat

Chat is a typical example where Node.js can be used effectively. It’s a very lightweight, high-traffic, and data-intensive application that runs across distributed devices. Chat is also a great place to start learning about Node.js as it takes into account some important topics related to a fully-fledged Node.js application.

2. Queued Inputs

For those who are receiving a huge amount of concurrent data, then there are chances that you’d find some road blocks within your database. As mentioned above, Node.js is great in the way it handles concurrent connections. However, since your database poses challenges while performing operations, the only solution for this recognize the client behavior before finalizing the written data in the database.

It’s a lucrative approach as it allows you maintain the responsiveness of the application in the situations of heavy load. This is particularly beneficial when the client isn’t sure about the data to be written. Examples include- writing about user-tracking data, those operations which you don’t want to showcase instantly such as ‘likes’ count of Facebook.

3. Production Purposes

Node.js is instrumented perfectly to meet the needs of application production. To this we mean that, Node.js boasts some exceptionally reliable set of tools that bring an application to full production performance abilities. Just like any sophisticated and growing technology, there are areas with some really helpful documentation, tools, and tested strategies, helpful in maintaining the flow of your work.

Summing It Up

Node.js is maturing impressively and is being used in mission and review critical environment. Its robust features and technologies are helpful in handling the complexities of modern web, while leading to increased productivity.
