4 mn read

In this digital era, a web app has become an essential business tool for a business. It provides a great many advantages like enabling a business to communicate with customers, collaborates with employees. Moreover, storing an enormous amount of data and providing better information to the management is streamlined with web Apps.

Apart from these, web Apps are a great way to increase a business’s brand identity online.


What should a good web App offer:

In order to be a successful application, you should develop a web app with all the necessary features. The primary motive of your Web App should be to provide a stunning user experience and as maximum interaction as possible. Besides, your Web App should be able to facilitate the completion of one or more tasks without any lag.

These are what separates web Apps from traditional, content-centric websites. Moreover, a user of a web App will arrive with specific goals, tasks, and expectations in mind, hence fulfilling all those in an effective way is the key to retain them.

To make this possible, we can use NodeJS.

What is NodeJS

NodeJS is an open-source, cross-platform runtime environment released in 2009 by Ryan Dahl. It offers web developers a simple platform to write, test, and debug JavaScript code. In other words, it is a powerful JavaScript runtime built on Chrome’s V8 JS engine. 

NodeJS uses an event-driven, asynchronous non-blocking input/output model. Besides, it operates on a single-thread event loop. These features made NodeJS fast, gave the ability to multi-task, handle several concurrent connections, and eliminated the wait for requests.

NodeJS is equipped with multiple application programming interfaces (APIs) that enlarge the capacity for back-end development in JavaScript. However, it doesn’t change the syntax or structure of JavaScript. Additionally, its HTTP requests, support for file systems, and reusable code assists in building dynamic web Apps.

Top companies that use NodeJS in 2021 successfully

JavaScript is the tried and tested language that can be utilized for both front-end and back-end development. Many skilled developers are choosing NodeJS to amp up their back-end development along with JavaScript. NodeJS is so popular as well as efficient that many industry leaders use it to strengthen their tech stack including, 

  1. LinkedIn

  2. Netflix

  3. Uber

  4. PayPal

  5. NASA

  6. eBay

  7. Medium

  8. Walmart

  9. Mozilla 

  10. GoDaddy

Benefits of NodeJS

NodeJS won the top spot in StackOverflow’s 2020 developer survey due to the following benefits it offers.

  • Light and fast

Since NodeJS uses Google’s V8 JavaScript engine, it effectively allocates memory, compiles, and executes JavaScript. Plus, the V8 is an open-source, high-performance JavaScript and WebAssembly engine. And, it compiles JavaScript into machine code employing a just-in-time (JIT) compiler before executing it.

Furthermore, NodeJS reduces CPU workloads and memory, making the application lightweight as well as fast.

  • Wider option of hosting providers

Due to its popularity and growth in recent years, it enjoys many cloud-based hosting providers and web servers. Hence, a developer can host Node.js code in a simple way. The notable hosting providers include Heroku, Amazon Web Services, and DigitalOcean.

  • Highly extensible

Although NodeJS doesn’t provide everything a developer need, it gives the option to add or customize the web App during development. So, the developer is relieved of unnecessary libraries. Moreover, it is equipped with Node package manager as the default package manager. NPM enables to browse and install over 1 million open-source packages. Also, these will assist in identifying and installing project dependencies.

  • Solid caching

Caching is nothing but storage of data for future requests. This helps the application to loads faster and respond quicker. Thanks to its functionality of fetching a request from the cache instead of the main servers. NodeJS has the ability to cache single modules which helps to increase the overall speed of the application.

  • Flexible Apps

One of the main attractive traits of NodeJS is it can develop flexible Apps that run smoothly on any platform. If you need a web App that should run on Linux, Windows, and Mac OS, NodeJS can make it happen. Furthermore, developers can create an App for different platforms with little or no modifications.

  • Scalability

NodeJS Apps are easily scalable both horizontally and vertically. It means new codes and additional resources are added to the existing system horizontally and vertically without much difficulty. Further, there’s no need for a large monolithic core while developing an App. Instead, a developer can make use of modules and microservices to communicate with lightweight mechanisms.

  • Automation

NodeJS gives the opportunity to automate repetitive operations. Besides, it can schedule actions, share modification records, groups functions, and keeps your code in order automatically. It has an extensive built-in library of UI templates that come in handy to increase user experience. Plus, ready-made modules, libraries, and code samples are open-sourced. So, the developer can configure the application easily and free of cost since it is open-sourced.

What Kind of Apps does NodeJS develop?

As I have already mentioned NodeJS is a powerful JavaScript runtime, hence it can be utilized to build almost any kind of application. Some of the top picks are,

  • Single-page applications (SPA)

  • Social media applications like LinkedIn

  • Real-time Apps and streaming Apps like Netflix

  • Ecommerce Apps like Walmart

  • Blogs and online Payment systems like PayPal

Besides, it can combine with other frameworks like ExpressJs to develop mobile Apps. Also, we can use NodeJS as a platform for Machine Learning and Artificial Intelligence training.

Final Thoughts

A high level of scalability makes NodeJS ideal for applications of various sizes and it requires less effort. Besides, its asynchronous execution and power to operate on a single-thread event loop helps to build high-performing applications. Hence, it is considered one of the top scalable frameworks.

Soft Suave has immense experience and knowledge working with NodeJS.
