Innovative features of Node.js app development

Building an app you expect developers to base it on a solid backend technology. You need a good foundation for your product that will hold it all together and allow the app to serve its purposes. For many, Node.js is a go-to technology for secure app development and there is certainly more than one reason for it. Today we will explore the flagship features of Node.js and share some of our favorites projects that we built thanks to them. Let’s go!

What is Node.js?

Node.js is a server-side runtime environment based on JavaScript. Which means it’s not a programming language nor a framework. It’s an environment that’s built on a JavaScript V8 engine that adapts JS functionality and syntax to backend development. 

Node.js was introduced to the coding society back in 2009. It was the first time developers could use JavaScript to build the backend of web applications. At first, it was available only on Linux and Mac OS but they didn’t have to wait long to be able to code in Node.js on Windows too. And the journey lasts till today as we enjoy building the server-side of applications working in well-known and established through years JavaScript. In fact, according to a Stack Overflow Survey on the most popular technologies from the last year, 51,9% of professional developers use Node.js on a daily basis. 

What features of Node.js facilitate the development process

As a client, you probably have a certain timeline in mind in which you want your product to be developed. Using technologies such as Node.js it is possible to streamline the delivery process and avoid delays along the way. It is thanks to a few innovative features. 

Non-blocking I/O and asynchronous request handling

Node.js uses an event-driven Input/Output model which makes it possible to process requests without any delays. Thanks to the asynchronous mechanism, the code isn’t executed in a sequence, so the requests don’t wait in a line to be finished. They are processed immediately without blocking the thread which results in short response time and concurrent processing. This particular feature makes Node.js a perfect choice for real-time applications, so any app that requires constantly updated data (video conferences, chats etc.)

Event-based model 

Fast processing is also enabled by the V8 engine. It is used to compile functions written in JavaScript into machine code. Because the engine was originally developed for Google Chrome, the company invested a lot of resources (and still does) to make it works flawlessly. In consequence, Node.js is able to process data at an impressive speed

Cross-platform nature

As a cross-platform software, Node.js is available to any developer no matter their preferred operating system. We’ve mentioned the advantages of cross-platform development when discussing React Native. The feature enables developers to use some of the code from a web application in the desktop version (Windows, macOS, or Linux). This way it is possible to code for multiple platforms at once, minimize errors and inconsistencies between systems, and reduce the time and costs of the project. 

Scalable technology for microservice development

Node. js is also suitable for microservices which are a popular solution among enterprise applications. Microservices break down the business logic into smaller modules instead of one large module like it’s in a monolithic architecture. Microservices don’t require developers to rewrite the whole application if they want to add new features. Building apps this way enables better flexibility and favors creating software that is scalable. How? It’s simply because adding more microservices on top of the existing ones is much easier, faster, and more pleasant than integrating additional features with the basic app functionality.

The ever-growing NPM 

Node Package Manager gives developers access to an enormous base of tools, frameworks, and modules to use. It includes over 836 000 libraries and is regularly updated. Thanks to the rich ecosystem, developers are able to work more efficiently, having a lot of opportunities to innovate code, thus build new solutions and reduce the overall costs of development. Increased productivity also leads to faster time-to-market. 

Which companies rely on the JS technology  

We selected 5 companies that trusted Node.js a long time ago and earn benefits till today. 

Walmart 

An American retail giant, operating several grocery and department stores across the world, made a shift to microservices using Node.js. The company wanted to improve their app so that the users could access several distinct functions using one platform. It turned out to be an excellent choice as the benefits were: 

  • Overnight 20% general conversion growth and 98% mobile conversion growth
  • 100% uptime on Black Friday 
  • Incredible savings (up to 40% on hardware, 20-50% on overall operations)

Paypal

Paypal is a well-known online platform for making electronic payments and it uses the JS technology to build user-facing content. It’s also an example of a company that made a great choice switching towards Node.js app development. In 2013, Paypal migrated from Java to JavaScript and Node.js and the results were pretty impressive. As the team stated, the new app was: 

  • Built almost twice as fast (with fewer people involved) 
  • Written in 33% fewer lines of code
  • Constructed with 40% fewer files

Trello 

A popular app for organizing work – Trello, offers virtual boards to manage different types of projects. As we mentioned, Node.js is a good match if you have a real-time application – no surprise it serves as the backend of Trello! The users expect immediate updates in their boards as they move tickets and that technology is able to provide an incredible performance. In addition, the company makes great use of the NPM resources. 

Uber 

Another one is Uber – a ride-sharing app, which was one of the first to use Node.js in production. The company explained in detail what technologies are the core of their product, frequently mentioning Node.js. For example, the systems that handle pings from riders and drivers that must operate in real-time are written in Node.js and Go. What’s more, Uber says that this technology allows sharing the JS code between client and server to create universal web apps. 

The three main reasons why Uber chose Node.js app development are: 

  • Ease of detecting errors
  • High performance and fast processing 
  • Continuous development 

Netflix 

The one and only video streaming platform for all the binge-watching enthusiasts closes our top 5 Node.js companies. Netflix chose to use Node.js to enable high-volume web streaming to over 182 million subscribers. Here’s where you can read about the evolution of Node.js at Netflix. Their 3 main goals were to provide: observability, debuggability, and availability. 

We’ve delivered some exciting projects built in Node.js

Our successful collaborations built with the use of JS technology.  

Launching a gaming auction platform

An Ireland-based entertainment company approached us with a need to build an auction platform for the gaming industry. Among the others, the project included creating a new digital currency – Von Coin, for making on-platform transactions and the development of a CRM for auction management. 

We based our choice on a reliable duo – React.js and Node.js that enabled smooth delivery and a successful launch!

Developing a platform for ads management 

We used Node.js during a collaboration with TraxOne. The client wanted to build software for seamless ad-creation for anyone who struggles with the online campaign setup. Our team took care of the front-end as well as the back-end of the solution, delivering the Conveyer app with a built-in CRM for performance tracking and analytics.

Building a solution for streamlining data collection 

LeadR was having issues with setting up one hundred campaigns daily, all directed at different targets. Our team stepped in to rationalize the end-to-end process, facilitate data collection, processing, storage, and the use of personal information. 

We developed a custom API that enables sending of a single email template to the service – without a footer – detailing the target database to which the email should be sent. In one word, we automated the process that was causing delays and improved the performance of our client.
