Anyone in the world



Node.js server technology is used to create and run a wide variety of web applications, and is quite similar to what Ruby On Rails, Spring Framework and ASP.NET does. It uses JavaScript as the main language, which is a lightweight built-in web server and has a plethora of Plugins managed via the Node Package Manager (NPM), allowing you to custom-build your applications to meet your needs. It may sound like any other good web technology, but it has certain features that make it a popular choice among developers to build a wide spectrum of web applications.


1. It’s lightning Fast


Node.js is primarily a JavaScript runtime that is powered by V8, developed by Google for use in Chrome. V8 has the ability to compile and execute JavaScript at lightning fast speed, mainly because it compiles JavaScript into a native machine code. 

In addition to this, Node.js has a magical event loop, which is a single thread performing all I/O operations in an asynchronous manner. In Node.js, when an application has to perform I/O operation, it sends asynchronous tasks and callback action to the event loop, and then continues to perform the rest of the program. On completion of sync operation, the event loop automatically returns to the task to execute callback. 

Node js can perform different task simultaneously at the same time. 

Thus, reading/writing to file system, network connections, and to the database is executed very fast in Node. It allows developers to build fast and highly scalable network applications that are capable of handling bulk amounts of simultaneous connections having high throughput.


2. It is Lightweight

non blocking feature

Typically, Node.js uses a basic event-driven architecture. This means everything executed on it, including every single operation and call, is a series of asynchronous callback. This enables Node to run on a single thread . This not only makes it light-in-weight, but also forms the foundation of Node’s non-blocking I/O feature.


3. A Single Language for All Layers


Another key benefit of Node.js is language re-use. Other web technologies like Spring or ASP.NET requires developers to have knowledge in another language to write code on the server-side, be it VB.NET, Java, or C#. This means all functions necessarily include two languages – one on the client-side and the other on server-side. 

 On the contrary, Node uses only JavaScript for the client and server side. Thus, web developers have to interact only in a single language across all layers which becomes convenient to code. This is also a vital reason for the super speed and performance of the web applications. In addition to it , this can be re-used again and again for future communications . 


4. High Performance


Performance Growth Graph

PayPal uses Node.js, and has reported doubling the number of requests per-second and reducing the response time by 35%. On the other hand, Wal Mart, the retail giant had a superb experience with Node.js in 2013, when they put all their mobile-based traffic via 


Node.js on Black Friday, the busiest shopping time of the year. Amazingly, on Black Friday, Wal Mart servers did not go over a mere 1% CPU utilization and yet they deploy with 200,000,000 users online.


LinkedIn, the global networking site, moved from Ruby to Node to handle their mobile traffic, and reduced the number of servers to 30 to 3, i.e. almost 90% reduction. The new system was up to 20 times faster. All these figures clearly indicate performance capability of Node.js.


5. It is Easy to Modify and Maintain




As today, we live in a digital world and users are increasing exponetially . So the traditionally built applications are  becoming less adaptive and rigid over time as new requirements are fed. Eventually, they start creaking under the stress they were not built for. Making changes in the code-base may be risky for the business if our business rely on it .

On the other hand , developing new services using Node.js is comparatively easier. With Node, a bunch of small applications is built instead of a single, large application. This allows making changes or adding a new functionality with much ease, without having to make changes deep inside the code-base.


Conclusion


Yes, Node.js is trending at the moment and its polularity is increasing with time . It has huge possibilities that developers can benefit to build highly robust and scalable web applications. So, it is worth a learn and explore possibilities in Node js . 


Corporate users of Node.js software include :-

1.   GoDaddy

2.   Groupon

3.   IBM

4.   LinkedIn

5.   Microsoft

6.   Netflix 

7.   PayPal Rakuten

8.   SAP

9.   Voxer

10. Walmart

11. Yahoo!.


The number is still increasing along with its popularity .

Why Node.js? What’s so special about it?

By Deepa Jilla

July 2020


Node. js is a JavaScript runtime engine for web server development, so before starting to learn node.js one needs to have some knowledge on JavaScript or web development.

But honestly speaking, for learning node.js it isn’t mandatory to have prior coding knowledge, just the willingness to learn, wanting to become a coder, continuous dedication and some hard work will be enough. 

If one wants to become a web or app developer in today's date, there is no better option than Node.js to start with, and let’s find out why?


What exactly node.js is? 

Written and introduced by Ryan Dahl in 2009, Node.js is a free, open-source server side runtime environment built on Chrome's V8 JavaScript engine. It provides an event driven, non-blocking (asynchronous) I/O and cross-platform (Windows, Linux, Unix, Mac OS X, etc.) runtime environment for building highly scalable server-side applications using JavaScript.


6_tUor8wPuVCh24YeMIey3J1pAR-1t2VpFDkYqiB-vj-1O9V7P-J1rb43-vgQYPq4gPN8TrpQvUldC8DA19rGy_ScGCXVbRbO5kxVbksVIJ9nAdn6BraNBv8cVItmPdRbNApTAgY


In simple words, Node.js is a platform for running JS script outside the browser. Node.js can be used to build different types of applications such as command line application, web application, real-time chat application, REST API server etc. However, it is mainly used to build network programs like web servers, similar to PHP, Java, or ASP.NET. 


9 Fantastic Utilities for the Node.js Developer

Node.js is a tool that's used in a variety of different ways in a variety of different workflows and for a variety of different purposes, like front-end, back-end, APIs, robotics and more.

Configuring Global Modules for Node.js: In node.js global modules are set up by default, and the npm docs have a quick guide that will help you configure global modules.

1. create-react-app - Fast Scaffolding of React Applications

Install:

npm install create-react-app --global

Create React App is a project out of Facebook to spin up a boilerplate application with React in just one command. It scaffolds out a barebones React application with the necessities, including development tooling and a local server, out of the box testing, and a build step to prepare your React application for production.

2. standard - Linting in JavaScript Made Easy

Install:

npm install standard --global

Standard is a pre-packaged Linter - there's zero configuration choices to make, there's just the Standard Style. Created by Feross, Standard is a JavaScript linter that's been widely adopted by a variety of projects. As a developer in the Node.js ecosystem, linting is an essential part of working collaboratively on both open source and work projects. Standard ensures that contributed JavaScript follows a consistent standard that's quickly verifiable with a simple CLI command. Following such a standard helps weed out stylistic bugs that can become problematic when multiple developers are contributing to the same codebase.

3. branch-diff - Diff Git Branches and Print the Results

Install:

npm install branch-diff --global

branch-diff is a CLI tool that differentiates two branches in a Git repository and generates a list of the differences between two passed branches. This list can either be output as Markdown or as console output. This small tool is useful when you're working across multiple branches and are looking to get a summary of the differences between two branches - for example when building out a changelog.

4. nodemon - Automate Restarting Node.js Applications

Install:

npm install nodemon --global

Nodemon is a small utility that will automate restarting a Node.js application when it detects a file change in the directory it's run in. Nodemon is a simple CLI tool that's extremely useful when working on a Node.js application and iterating quickly - it will cut out the repetitive steps of switching to your terminal, ending the application's process, and then restarting the application.

5. localtunnel - Expose localhost Applications Publicly

Install:

npm install localtunnel --global

Localtunnel is a helpful module that will expose an application running on localhost with a single command. There are a couple examples of when you'd want to use localtunnel. For example, if you're working with APIs and need to provide a public URL, you can use localtunnel to get an online, accessible URL without the need to deploy. Additionally, it's excellent for collaboration - you'll be able to quickly set up a preview of what you're working on to share.

6. now - Deploy Node.js apps, Dockerfiles, and Static Sites

Install:

npm install now --global

Now is a small service from Zeit that allows you to deploy Node apps, Dockerfiles, and static sites to production quickly. It's great for prototyping out applications and deploying them to the web fast.

As an added bonus with Now, you can even deploy NodeSource N|Solid with the N|Solid Docker image to Now.

7. david - Find Out When Your Dependencies are Outdated

Install:

npm install david --global

David is a utility to let you know when a project's npm dependencies are out of date, and provides a way to update any outdated modules easily. One nice feature about David is that it can be used both on a project-by-project basis or as a global module. This means you can enable dependency checking inside modules you publish or work with in addition to having the ability to check modules on a case by case basis.

8. nvm - The Node Version Manager

Install:

# Since nvm's not an npm module, you can install with cURL or wget

# Install with cURL:

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

# Install with wget: 

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.0/install.sh | bash

While not a Node.js module, nvm is a CLI tool that's extremely helpful for Node.js developers - it, as you may have guessed, allows version management of Node.js. This means you can download, swap, and test on any version of Node.js. This is handy for testing modules on the Current release line, in addition to the LTS release lines.

9. npm - The default Node.js package manager!

Install:

npm install npm --global

Something that many people don't consider is that the npm CLI is, in fact, a module - if you're using npm as your package manager of choice, updating the CLI consistently is considered practice. Each version of Node.js has a specific version of npm tied to it - that version is usually going to be behind the latest release of the npm CLI. You can get the latest version of the npm CLI by simply running a global install with npm!

 

5 Reasons to Choose Node.js for Web Development

Node.js today plays a critical role in the technology stack of many high-profile companies who depend on its unique benefits. Compared to other web development technologies, Node.js is more popular. So, here are the 5 main reasons to choose node.js, especially for people looking to start their career in web development.

  1. Unyielding demand: The demand for Node.js has been continuously rising. In fact, Node.js overtakes Java ( the most popular programming language so far).

  1. More number of jobs in Node.js development: Less development time, requirement of less number of servers, and unparalleled scalability offered by Node.js are the major reasons why companies are adopting it.

  2. JavaScript is used extensively: The best part about Node.js is it uses JavaScript. JS is the simplest and the most popular way to develop apps in the browser. Generally, to develop browser application and server-side application JavaScript and an additional programming language such as PHP, Ruby, Python etc is required. With Node.js, you can use JavaScript to develop both browser as well as server-side applications. Hence, you would be required to learn JavaScript, but no additional server-side programming language. Compared to other languages and their event-loop systems, e.g. Python and Ruby, JavaScript proves to have better performance. Plus, there’s less room for human error, as programmers can avoid mental switching between browser and server.

The NASA application is focused on keeping astronauts safe during their space expeditions. After an accident in which one of the astronauts nearly lost his life, NASA faced a challenge of moving all data of EVA spacesuits to a single cloud database. They adapted Node.js which helped to decrease the number of procedural steps from 28 to 7!

“The system he is creating uses a microservices architecture with separate APIs and applications built in Node.js to move data related to the EVA spacesuits from three separate legacy databases to a cloud database. Now users can query that one database for everything, reducing the time to access a comprehensive set of data by about 300 percent.”

Benefits:

  • Single database  

  • The access timelines reduced by 300% 

  • Less procedural steps

Mozilla Firefox, one of the world’s most popular Internet browsers, was using Node.js for: 

  • Express, a web framework that is written in JavaScript and hosted within the Node runtime environment. 

  • Mozilla Persona, a cross platform sign in technology based on the BrowserID protocol (closed in 2016). 

According to Mark Mayo, principal engineer at Mozilla who was working on Mozilla Persona, the company chose Node because of two key reasons: memory footprint and cryptography.His team encountered several challenges while implementing Node, but in the end, they got everything in a single JavaScript repository, without any other languages or dependencies.

In April 2017, Twitter released Twitter Lite, a mobile app with minimum functionality that can work with slow Internet connections. The app minimizes the data usage, is resilient on unreliable mobile networks, and takes up less than 1 MB on any device. 

The Twitter team used Node.JS to build, test, and deliver this application. Before Node.JS, the company had a different technology on the back end and spent lots of time-solving the operational issues. 

Node.js Is The Future 

The IT community called Node.js the "digital transformation". Whether it is about the micro service development, delivery of handy mobile apps, or the integration of the non-web system with the serverless framework, NodeJs offers a strong foundation. 

The IT industry always looks for a long term solution and the IoT is the real future. The technology which supports IoT will survive amidst the continuous development and research. NodeJs is a strong tool for complicated software infrastructures and fuels the as-as-service methodology. It heads the node js development company to cater to industry needs. As-as-service and server-less programming are the existential requirements of the businesses, where Nodejs highly support these areas. 

Verdict: A great level of flexibility and utility is the long term demand for continuous growth. Alongside, fast execution, better utilization of the memory and great level of security are the dynamic demands which keep increasing comparatively. Hence forth, it is affirmative for a company looking to hire node.js developers. 

The mobile application is no more divided into two completely different paradigms. The codebase for android can easily be used as a ground for the iOS-based application which bridged the gap and saved the cost/time for development. NodeJs is the secure future because of its adaptability to varying needs. Node.js is the stable solution for implementing the cloud services, Saas and Paas along with the enhanced debugging tools.

Summary 

The Node.js ecosystem has been gaining major traction due to its features and efficiency. With a number of global brands continuously increasing its usage upon their platforms, the framework is observing good growth. In today’s scenario, the best way to increase the efficiency and scalability of your web applications would be to switch to Node.js. Here are some important points to remember about node.js.

  • Great for prototyping and agile development.

  • Powered by the Google V8 engine which adds the fuel to its already high performance.

  • Cleaner and most consistent codebase.

  • Large ecosystem of open source libraries.

  • Cross-platform framework that runs on Windows, MAC or Linux.

  • Uses JavaScript to build the entire server side application.

What is Node.js?

Node.js is an open-source JavaScript runtime environment that executes JavaScript code outside of a browser. It was built on Chrome’s V8 JavaScript engine with scalability in mind. It is perfect for lightweight and fast real-time web applications. So what is so interesting about Node.js that attracts more and more companies? Well, it’s amazing for creating collaboration tools, chats, social media applications and many more. What is more, according to Stack overflow, Node.js is among the most popular technologies.

Node.js also provides a rich library of various JavaScript modules which simplifies the development of web applications using Node.js to a great extent.

Special About Node.Js

NETFLIX

rb7XvO188M-QumCtwqT8YiZfTN0magk_6H-Q95xpp_jGrpftQRDcISV43GX9eG5qfFZ_BhQZiZ9qis8rtuYZrY8JOla3Dnqb-SjRrOM3q0ZER92vwTDb__cekvmxpVpeNcTB3X8l

According to the latest StackOverflow survey, astonishing 49,9% of the professional developers, who participated in the voting, named Node.js as the most commonly used technology. Angular took the 2nd place with 37,6%.

YWoCKIj-8BBj8MuiNSTJSk6kVuEz4kgjmL_aRaTxxhwlcvAJXSFzjaJ_Rd8WEh9b9QdXb03Qg4OdHgAs9dWIE7D3gDfpSB2SAkAaC7jL4cUyYpliYjHTwFiR3SQwNqnRBQ1eLnxe

That made me realize that many people who are not familiar with the technology are not aware of how often they interact with it. I’ve started to dig deep into who and where uses Node.js in their product. The most famous examples were discussed on various other resources, but my hunger was not satisfied so I decided to gather as many useful samples as I was able to find. Which happened to be 27. Unfortunately, not every company likes to talk about its tech stack. Hence, you’re facing a list of 16 companies that use Node js.

NETFLIX - HOW NODE.JS REDUCED STARTUP TIME

I believe this one does not require an introduction. Netflix has reached 130 million subscribers in June 2018 and requires an extremely scalable solution to handle all the requests and approx. 1 billion hours of weekly video data streaming.

 

When it comes to reasons why the decision to switch from Java on the backend to Node.js, there are a few of them. The Netflix team wanted to have the same language both on the back and frontend side of their product (their frontend was already written in JavaScript), build a single page and, what’s very important, to decrease its startup time. Thanks to Node’s performance, they have managed to go from 40 minutes to under 1 minute.

PAYPAL

oTpTLsVYjuYyq8Ff9h6zt96pn-Lb21vsgijK8KnBUqQ0XavLcyxulXWw7pH-bZCiAragr7YFd8QQBMUG99CKTH0VX7dMHHY0BZBab9t438G8PGqyyFF3HM8iCpaxMZEugOUHtuTc

PayPal, one of the largest fintech leaders, has also trusted their back-end development to Node.js. Originally Paypal shifted from Java to JavaScript by experimenting and developing two Java and Node.js applications at the same time. After two apps with the same functionalities were ready, they were tested and compared and here what the engineers learned: Node.js app was built almost twice as fast with fewer people, there were written in 33% fewer lines of code while developing in Node, and the app was constructed with 40% fewer files. In his talk at Node.js Interactive 2015, Matt Edelman, NodeJS Infrastructure Manager at PayPal, is telling about how the company tried to adopt the language change, how much their developers loved this technology and what challenges there are when you decide to use Node.js implying that it is challenging to keep up with the active community of Node.js developers.

PAYPAL - BETTER PERFORMANCE THANKS TO NODE.JS

If I assume that you’ve used PayPal at least once, I can probably be fairly sure I’m not wrong. With its flabbergasting $451bln in annual payment volume and 244 million active worldwide users, PayPal made a decision to migrate from Java to JavaScript and Node.js back in 2013. This resulted in 200ms faster page response time and doubled the number of requests they could handle per second.

 LINKEDIN

7Pl_IIxpBiCrkiU4cKNqMNXngMk144HdiUFP6Gow68HnLehn3YrH935_nRNPGVXuyDiv9cvKPkty7CEkoemxdcYjSCdx1pqX-tgQ68I-o3JTX2hGDuKmrk-Fy-WcMKNrpe3Luj98

Back in 2016, Microsoft acquired LinkedIn. Mind-Blowing $26bln-worth transaction granted Microsoft access to the biggest business-oriented social media platform. As you can imagine, social media is virtually impossible without mobile use. According to Statista portal, LinkedIn had an average of 63m unique members using their mobile applications, which accounted for 59% of all unique members during the same 2016.

 

To perform at such a scale you need to have a great technological solution in place. Node.js is the one for LinkedIn. They switched to it quite some time ago, in 2011, and had no regrets ever since. When it comes to benefits that came along with that decision, there are quite a few. In a VentureBeat’s interview with Kiran Prasad, LinkedIn’s mobile development lead at the time (now VP of Product) said that their mobile software stack is built solely with Node.js.

 

“We use a ton of technologies at LinkedIn, but for the mobile server piece, it’s entirely Node-based.One reason was the scale. The second is, if you look at Node, the thing it’s best at doing is talking to other services. The mobile app has to talk to our platform API and database. We’re not doing massive data analytics. Node showed us huge performance gains compared to what we were using before, which was Ruby on Rails.”

UBER

W0vFWYkOWEGRg_HC2pZV-iEs82PNmfiCzHv073O3CZfEVcHrbGadhmTQs4cbJRvqQ1xVO2TaK-eK9SiYjmlONj21nQTNgkO6uMi5DrqxCGX7iT0Gnjfit0rr56sQD23UjC8E7uG6


Lately extremely controversial, Uber was one of the first 3 companies that put Node.js into full production. They required an extremely fast and scalable cross-platform technological solution that could handle an enormous amount of notifications and requests. Considering that matching riders and drivers is the foundation of Uber’s business, zero risks could be taken when it comes to building their matching system. And quite frankly, Node.js was exactly what they needed.

 

The second reason was quick iterations. To explain it, let me quote Uber ’s Senior Staff Engineer - Matt Ranney:

 

“One of the things that make Node.js uniquely suited to running in production is that you can inspect and change a program without restarting it. So very few other languages offer that capability. Not a lot of people seem to know that ability exists, but indeed you can inspect and even change your program while it’s running without restarting it.”


WALMART

5Fp3iRQi5z8C_p3ozPfMjBv8nffuKMsFwUhE7y3rXfY3Wy2qf4MGb0ZU4O8_k1LU52fjGZzlKiWwm0lFFeNDlOabQwGPE3jHtYQ6zoPag_cIq-36EQKN0kSBaP8gomNhPn8hJoY-

Walmart is the world’s largest retailer with approximately the $481.32 billion global net sales in 2017. The company has chosen to work with Node.js despite the risk that it was a really young technology. Walmart re-developed its mobile app to provide more advanced features on the client-side. The development team especially appreciated the Node.js famous asynchronous I/O and its single-threaded event loop models that can efficiently handle concurrent requests. Alexander Grigoryan, Sr Director of Software Engineering at Walmart Group, in November 2016.

$500bln worth of worldwide revenue, according to Statista, powers the world's largest company revenue-wise. Retail giant operates under 59 different names within 28 countries and, as you can imagine, serving approx. 270mln customers weekly is a hell of a mission.

 

Walmart discussed their transition to Node.js back in 2012, when during Node Summit, Walmart’s VP for Mobile Engineering, Ben Galbraith, and VP for Mobile Architecture, Dion Almaer, took the stage to talk about their decision to switch to Node.js in Walmart’s mobile applications.

 

Since then, their connection to Node.js and JavaScript, in general, has grown quite radically. When interviewed in 2017, Walmart’s Senior Director of Software Engineering, Application Platform and Online Grocery, Alexander Grigoryan has voiced his reasons for using JavaScript-based technologies.



 

Besides the technical ones like better performance, modularity that allows to implement changes and fix bugs much faster, he also focused his attention on how much easier it is to find a JavaScript developer:

 

“It's easier to find JavaScript developers than many other kinds. And once hired, a JavaScript developer on the Electrode/React platform is a full stack developer.”

MEDIUM

sg0iiUeWc_lGWPcrBjb4uNiInVh5esSU-z5gAvY-i2fa5X-AcPPRwLZ7enqBquNrXRybjYf1-U1tAmkz5f3KkPHIevJWQunC6WwUNsZOu8NQhB_1xK3UPdONTg-h73-0Dk60b7EI


Medium, one of the world’s largest online publishing platforms, too, uses Node.js for their web servers. Maybe Medium web app can seem just a simple web HTML page, there is much more technology behind it, alongside all the challenges that the company faces. Medium is a data-driven platform that evolves along with the users and their behavior. Node.js is particularly useful when it comes to running A/B tests to get a better comprehension of product changes and experiment with new ideas.

EBAY

EBAY - FASTER ITERATIONS WITH NODE.JS

Operating in 37 countries, eBay has 175mln buyers as of July 2018th and requires not only scalable but fast and reliable solutions. Most of the eBay stack is Java-based, but they’re also keen to adopt new technologies to developer their eBay specific services and that’s when JavaScript and Node.js came on board.

 

Senthil Padmanabhan, eBay’s VP, said the transition wasn’t the easiest one: “Since eBay revolves around Java and since Java is a strongly typed static language, initially it was very difficult to convince folks to use JavaScript on the backend. The numerous questions involved ensuring type safety, handling errors, scaling, etc. In addition, JavaScript itself (being the world’s most misunderstood language) further fueled the debate. To address concerns, we created an internal wiki and invited engineers to express their questions, concerns, doubts, or anything else about Node.js.”

Another Lead Developer, John Cline, who had been working on recommendations and the updated homepage, had this to say about moving to Node.js:

 

“The decision to migrate to JS and Node came for two reasons. One was to build off the great work PayPal has done with KrakenJS and switch to a modern platform that developers are excited to work for.”

 

Following with:

 

“The second came out of some frustration with our front -end engineers. The existing platforms take a while to startup, and as anyone who’s developed web applications with Java and Eclipse knows that all sorts of issues come up. Moving to Node for our front end is a big time saver and helps us iterate much faster.”


NASA

NASA - NODE.JS HELPS EVEN IN SPACE

Whenever we think about space, most of us find it too difficult to comprehend. And bringing our species to space is definitely a hell of a task. The system behind it should grant as much security to people in the vast and unfriendly vacuum as it is possible. When during a regular spacewalk in 2013, Luca Parmitano, one of NASA astronauts, spacesuit started leaking water into his helmet, NASA started an investigation on what exactly happened. Turned out it was not a simple task either, due to the system’s architecture that was in place at the time.




According to Node.js Foundation case study, NASA decided to migrate to Node.js and here’s what it helped them to achieve:


“The system he is creating uses a microservices architecture with separate APIs and applications built in Node.js to move data related to the EVA spacesuits from three separate legacy databases to a cloud database. Now users can query that one database for everything, reducing the time to access a comprehensive set of data by about 300 percent.”


YANDEX

Yandex. Yandex is the Russian Google if I would have to explain it the simplest way. They happen to be a heavy JavaScript user for quite a while now. For example, Yandex. Money - the largest electronic payment service in Russia according to the TNS report, uses React.js on the frontend and Node.js, specifically Express.js, on their backend side.

 

The reasons for such a decision are pretty obvious. The project is JavaScript-based, making it much easier to scale the team as well as understand the whole code repository, Node.js easily communicates with their main Java-based backend through various APIs and Node’s broad community serves a great help when such help is needed.

In Yandex office, their frontend team constantly monitors their system performance



Besides, all these above-mentioned industry leaders, there are many other big and small companies that chose to use Node.js in production. Among them, you can also find Microsoft, Google, Yahoo, Mozilla, or Github. As this technology is developing more and more companies will, of course, try to take it up as it is fast, simple, performant, and completely effective.

“Node.js took JavaScript everywhere!

Simply, we started using Node.js in 2012. From that time on, this unique and incredible JavaScript technology has our hearts. We have done a number of big and small projects in Node.js that stand out with their lightness, speed, and great performance. All of them are shining like diamonds everywhere due to the technology we use, and, of course, the expert job of Simply JavaScript ninjas.
