TOP 7 companies using NodeJS in Production: Best Examples

What is Node.js? And Why JavaScript Is Greeting The World?

Node.JS is an open-source, cross-platform JavaScript runtime environment. Node used for developing a diverse variety of server tools and applications. Node.js is not a JavaScript framework, many of its basic modules are written in JavaScript and developers can write new modules in JS.

Ben Halpern cited Atwood’s Law: “Any application that can be written in JavaScript, will eventually be written in JavaScript.”

Once only thought of as a “popular” framework, NodeJS is fastly becoming one of the TOP commonly used languages in coding web apps and is beginning to find its way into Enterprise solutions.

Below is a list of 6+1 big companies that have implemented the popular server-side JavaScript engine for use inside high traffic & profile production projects.

What reason are the biggest companies using Node.js for?

#1 Microsoft

Net income: ▴ $21.20 billion

Microsoft Co is working with Nodes in several Ways: offers direct integration with the Azure Platform, releasing many programs for learning Node-oriented, and Microsoft plans to create its own version of the Node engine running on the Edge Javascript engine, not in the V8 version of Chrome. Look at some ideas in this video:

#2 IBM

Net income: $11.87 billion

IBM also adopted NodeJS. Why did IBM use Node.js see in this video: Myles Borins talks about his experience with CITGM.

#3 PayPal payments

Net income: $1.4 billion

PayPal also prefers JavaScript and NodeJS for use on its web platform. For PayPal, the use of NodeJS began as a platform for creating prototypes, and later introduced into production.

The first use of NodeJS in production — it was their account overview page, one of the most downloaded. The JS team was able to build a faster and more efficient product. After that, PayPal prepared an Open-Source solution for ExpressJS called KrakenJS.

Why did PayPal choose Node.js?

#4 Cisco

Net income: ▾ $9.61 billion

Cisco Systems, Inc. is an US-based technology conglomerate headquartered in San Jose. That develops, manufactures, and sells networking hardware, telecommunications equipment, and other high-technology services and products. Through its numerous acquired subsidiaries, such as OpenDNS, WebEx, and Jasper, Cisco specializes into specific tech markets, such as Internet of Things, domain security, and energy management.

+1 Capital One

Net income: $3.75 billion

Capital One Co. is the largest FinTech companies in the USA and they’re using all-in on Node.js.

The Capital One story is remarkably and I highly recommend you check out the official Node.js Foundation Case Study with Capital One. They used NodeJS and Other technology stacks to collect Big data and processing to generate personal loan proposals.

A talk by Azat Mardan that tell how/why Capital One Co. uses Node JS on this video (2015, Portland, OR):

What Lessons Can We learn From Companies That Use Node.JS

  • Node.js is being adopted by businesses because it enables them to outpace their competitors by delivering new products and features more quickly.
  • The ability of Node.js to enable full-stack developers is driving efficiencies in the enterprise.

Node.js is an open-source, cross-platform runtime environment written in JavaScript, the most popular programming language in the world. It’s biggest strengths are versatility, lightning fast speed of processing and high scalability.

By the way:

Along with the efficiency and simplicity of Node.js, there is also sort of ‘neighboring’ tech called AngularJS. This framework is frequently used in a bundle with Node.js. Get familiar with AngularJS and big projects where it runs — head through the link to see the best AngularJS examples (Wix, UpWork et al.).

Best Node.JS Open Source Projects

Recently, there has been a lot of talk about a new trendy technology in the world of web development. What exactly is Node.js and why did it become so popular in a short term? Is it worth to study at all?

As of lately, there is no shortage of training materials on Node.js, but most of them cover either some specific use cases or topics that are applicable even when you have a working Node.js Here and there I see comments like “I downloaded Node.js, what do I do now? “. The article will answer this question and explain what Node.js is and what the best open source projects are.

What is Node.js?

Node or Node.js is a software platform based on the V8 engine (translating JavaScript into machine code), which turns JavaScript from a highly specialized language into a general-purpose language. Node.js adds the ability of JavaScript to interact with I / O devices through its API (written in C ++), connect other external libraries written in different languages, providing calls to them from JavaScript code. Node.js is used primarily on the server. Node.js is based on event-oriented and asynchronous (or reactive) programming with non-blocking I / O.

It is important to understand that Node is not a web server. It does not do anything by itself. This is not Apache. There is no config-file, which indicates the path to the HTML-files. If you need an HTTP server, you need to write an HTTP server (using built-in libraries). Node.js is just another way to run code on your computer. This is just the environment for running JavaScript.

Reasons to use Node.js in projects

+Programs from Google, IBM, Paypal and other well-known corporations are scripted with the help of Node.js programming language. Node.js open source projects are so popular since NODE.JS processes are executed in parallel, the whole system works much faster and copes with large loads, which means stability and speed of your application.

+Another great feature of best open source Node.js projects is the ease with which you can create soft real-time systems. I mean things like Twitter, chats, bets on sports events or interfaces to IM-protocols.

+While Node.js is still very young, there is a temptation to write specifically everything that you needed. But it can be much more beneficial to use a huge selection of pre-existing command-line tools. Node is able to generate thousands of processes and work with their output data streams, which can give serious advantages to those who do not want to reinvent the wheel.

+The Node.js community is now growing at a frantic pace, attracting the best developers in the industry. This means that the Node ecosystem is also growing, it is increasingly easier to get support for free or on a commercial basis.
