Node.js happens to be one of the most popular development technologies in the U.S., powering over 6.3 million websites. Node.js is becoming more popular as a way to build real-time applications. The main benefit of Node.js is that it works asynchronously and is driven by events. This makes it the best choice for projects that need to be done in real-time.
With technologies like Node.js, it’s easy to make real-time web apps that respond to requests almost instantly, even when a lot of people are using them at the same time.
Read on to learn why Node.js is such a popular tool for real-time application development.
What is Node.JS?
Node.JS is an open-source JavaScript environment for server-side development. Ryan Dahl started the environment in 2009, and it has since become a mainstay in the development world. NodeJS is very fast because it uses the V8 JavaScript engine and the core of Google’s Chrome browser outside of it. Node JS is a great choice for developers working on real-time applications, and it has worked well in similar situations across the industry.
Roles of Node.JS in Real-Time Apps
In a real-time app, Node.JS plays the following roles:
Getting information from users and using it in real-time
Making content that changes for users
Taking care of and fixing data in multiple databases
Taking code off and putting it on the server
Why Node.JS is Best for Real-Time Apps?
Here are some of the reasons why Node.JS is perfect for real-time apps.
Single Code For Server And Client-Side
Developers who work on Node JS write the same code for both the server side and the client side. This makes it very easy for them to share information and work together in the best way possible. Developers working with the Node.js framework no longer have to write code that works on its own, which saves them time and lets them run the code as it is.
One Single Language
Node JS is becoming more and more popular because it only uses one programming language, JavaScript. Using just one language can speed up the development process and improve results, which can lead to solutions that are more secure and can be used by more people.
Node.js developers can now update codes quickly and don’t have to spend days or even hours making changes to codes in different languages and code.
Speed
Web apps are only as good as how quickly they work. Users are tired of waiting for your server to load, and they’re also tired of waiting for a web application to give them an accurate answer in real-time.
Thanks to Node.js, you can process huge amounts of data in seconds and stream that information back to your end user without needing an army of servers to keep up with all the requests. Thus making it ideal for web app development.
On top of that, if your Node.js app needs even more speed and scalability, there are a lot of load-balancing solutions for high-volume traffic that don’t require you to know anything about server administration. Top Node.js development companies utilize this trait of Node.js to their advantage. They plug load-balancing solutions into your backend code and get the job done.
Event-Based Server
JavaScript is different from most programming languages because it is event-based. This means that it reacts to things that happen instead of making you set a series of conditions and then decide what to do next based on how those conditions turn out. This makes coding very easy and quick.
It also makes it possible for a system called non-blocking I/O or asynchronous I/O(AIO), which is even better. AIO lets you use one processor to do several different jobs at the same time, so you don’t have to wait for something to happen while a single processor is idle.
It’s the best kind of parallelization. An AIO system would never slow down because there wouldn’t be any slow parts holding up the rest.
I/O Bound Tasks
One of the benefits of using Node.js is that it handles I/O-bound tasks very well. This means that a Node application will respond faster and use less memory than an application made in another programming language.
In fact, some studies have shown that code written in JavaScript runs better on Node.js than code written in Python or Java. Because many programs have to deal with slow input/output operations, like reading and writing files, Node.js can do these tasks faster than almost any other type of program.
This also makes it a great choice for API-based applications like chat rooms and interactive websites, where users need real-time data updates to stay interested in your site at all times.
Wide Range of Modules and Tools
Node.js features a module system that is similar to that used in many other programming languages. This enables the addition of community libraries, which can be freely shared and have already been tested.
Furthermore, because modules are only loaded when they are required, it helps with resource usage and ensures that developers do not have to worry about unneeded code taking up memory while developing an app.
Because you won’t have to deal with enormous blocks of unneeded code while working on little bits at a time, your application will run faster and be easier to develop and test.
Apart from the modules, there is a wide range of Node.js development tools that help the developers quickly add new features or improve the performance of an existing codebase.
Better Reusability
There are many libraries and plugins for Node.js that can be used for any task or need. The developers don’t have to keep making the same things over and over. Instead, they can use parts that have already been made.
NPM is a repository with thousands of ready-to-use packages that any developer can find, download, try, and use to make their projects easier and faster to build than ever before.
Here you can find different kinds of modules that let you do things like build an HTTP server, read files, and even send emails. This makes it easier and faster to build as the Node.js developers don’t need to make their own module if there’s already something that fits your needs.
Data handling
Node.js uses event-driven data architecture. It takes in and sends out events and lets you listen to different types of events in a very flexible way. This makes Node.js a powerful tool for working with data.
For example, your users can provide real-time updates and even add new information to your database right from their smartphones or tablets while they are on the go. Then, you can run some logic on that user’s data right away (as it comes in), or you can schedule that data to be handled at regular intervals when you have time, whichever works best for your project.
All of this means that there will be less time between when something happens and when something is done in response.
Bottom Line
If you are working on the construction of real-time applications and are seeking a programming language that is both powerful and simple to use, then you absolutely need to give Node.js a shot.
