Why use Node.js? Examples of Node.js Applications.

This article will talk about why use Node.js and examples of Node.js applications. Let’s find out more about Node.js and its Applications.

What is Node.js?

Node.js is one of the newest and most liked programming languages. It is particularly useful for creating backend software. Node.js was created using Chrome’s V8 JavaScript engine and it was originally designed in C++.

Ryan Dahl initially came up with it in 2009. He decided to create a lightweight, user-friendly environment as a result.

And thus, it came into existence. You’re probably wondering why use Node.js at this point. It is mostly used for non-blocking, event-driven servers, and is used for server-side programming.

Is the programming language Node.js?

It is important to realize that Node.js is a runtime environment rather than a framework or library, as is the case with conventional application software.

A developer can use a runtime environment to produce code and a JavaScript engine to parse that code. A runtime environment is a set of web APIs. This makes it portable, adaptable, and easy to deploy, all of which will help you optimize and accelerate the development of your application.

After finishing this quick crash course, you’ll be prepared to continue learning about the advantages of choosing Node.js for your app development over other tech stacks.

Why use Node.js?

Real-time web apps using push technology rather than WebSocket shine when written in Node.js. We finally have online applications with real-time, two-way connections, where both the client and server may begin communication, allowing them to share data more freely, after more than 20 years of a stateless web based on the stateless request-response paradigm.

Contrast this with the traditional web response paradigm, where the client always starts the communication. It may be argued that Flash and Java Applets are examples of technology that have been around for a while.

However, in actuality, those were essentially sandboxed environments that were given to the client through the web’s transport protocol. Additionally, Flash and Java Applets ran independently and frequently used nonstandard ports, which would have required additional permissions.

Examples of Node.js Applications

Netflix

With about 183 million customers in 2020, Netflix is one of the biggest streaming services worldwide. As Netflix grew in popularity, launch times and the online application as a whole slowed down. Netflix picked Node.js because its engineers were already proficient in JavaScript, saving them the time and effort of having to learn a new language. They also liked the features that Node modules provided.

I hope you’re seated because the figures are about to arrive. Netflix was able to reduce its start-up time from 40 minutes to under 1 minute by implementing Node.js!

PayPal

Over 325 million PayPal accounts are active globally. PayPal’s net payment volume in the first quarter of 2020 was 190.57 billion USD. Those are a lot of numbers; you have to accept them.

PayPal chose Node.js to construct the user-facing portions of its online application. Since both the server and browser apps are built in JavaScript, another advantage of Node.js that they enjoy is the cohesive team of engineers. The development team at PayPal accelerated the app while increasing modularity by utilizing Node.js.

With the addition of Node.js, PayPal’s capacity for requests per second was doubled, and page response time was reduced by 200ms.

LinkedIn

With over 675 million members by 2020, LinkedIn had been bought by Microsoft in 2016 for the shocking price of 26 billion USD.

Node.js is wholly Node-based in terms of the mobile server. The LinkedIn team determined that simple scalability and connectivity with other services were two particular Node.js characteristics that were essential for their project.

Twitter

With more than 330 million active users each month, Twitter is an extremely well-liked social networking site. Additionally, it is in the top ten most popular websites worldwide.

Twitter has seen several redesigns and alterations since its debut in 2006. In 2017, the firm decided to transition to Node.js, and ever since they started using it, Twitter’s developers have been happy with the development pace it provides.

Twitter needed a language that would enable them to make changes quickly and deploy them right away, which was the driving drive for the transition. Node.js was the ideal solution in that situation, and it has since made it easier for the business to expand and go forward.

Uber

Uber completes more than 14 million journeys per day and is accessible in 65 different countries and 600+ cities. Throughout 10 billion trips, approximately 4 million Uber drivers have taken customers to their destinations. I assume when we order an Uber home after a night out, we don’t consider the magnitude.

Uber required an extremely quick and scalable solution to manage the millions of alerts, passenger-driver matches, and requests it receives every day. They chose Node.js because it handles a lot of data rapidly and allows for program inspection, modification, and mistake correction without necessitating app restarts. The Uber development team is now able to produce and release new code and updates as needed.

Coursera

To offer online courses, certifications, and degrees, Coursera collaborates with prestigious colleges and organizations. It offers many degrees and master’s programs in addition to more than 3,000 courses.

Two Stanford academics launched the business in 2012, and it currently has more than 33 million customers globally.

Since its debut, Node.js has been the sole platform used to build Coursera. The business required a JavaScript framework that would facilitate quick development and simple scaling. Given its portability and abundance of modules that may be utilized to enhance an app, Node.js was an obvious option.

Conclusion

As you can see, there are several benefits to using Node.js for creating websites and mobile applications. It contains a large ecosystem of modules that facilitate development and is quick and scalable. It is also utilized by some of the most well-known apps in the world and supported by Amazon Web Services.

And why use Node.js? Node.js is the clear choice if you’re seeking a JavaScript framework that will assist you in creating an app fast and efficiently. But bear in mind that it will be challenging to utilize this technology to its fullest extent without a team of specialists and UX/UI designers.
