Node.Js become a gold standard for Enterprise Web Apps? - Node.js can be extended using third-party modules for creating feature-rich enterprise web applications due to the vast ecosystem that is built around it…
How a browser processes JS code?
A browser has an in-built JS engine within its runtime environment to process JS code.
You would write document.getElementById(‘’); for picking an element using the DOM. However, this code is only understandable by your browser’s JS Engine.
How Node.js processes JS code
Node.js Development incorporates Chrome’s V8 engine and embeds it inside a C++ program. It also has certain objects that provide an environment for our JS code. This is different than using DOM. These capabilities of Node open a door of possibilities for developers and enterprise applications which are not possible on a Web Browser.
Few examples not possible on a browser:
Commands like fs.readFile() let you work with a file system.
You can listen for requests on a given port using http.createServer().
Node.js is most often used to build backend services like APIs for powering web and mobile apps. Node.js allows you to build services that these web and mobile apps can interact with, such as store data, send emails and push notifications, trigger workflows and so on. It is ideal for building highly scalable, data-intensive and real-time backend services that power client applications.
Node.js is asynchronous and non-blocking in nature for all I/O. It is based on an event-driven architecture. These two features are critical to Node’s performance, throughput and scalability for building large scale enterprise web applications which have a huge volume of transaction input/output operations. Not just enterprise solutions, but even games and web apps which involve real-time communication and data synchronization are effortless using Node.
Let’s understand what asynchronous and non-blocking nature of Node.js means with the help of a metaphor.
In a restaurant, there are multiple tables. Once you place an order with the waiter, the chef in the kitchen starts preparing your order. Meanwhile, the waiter can proceed to take other orders from people in the restaurant while the chef prepares your meal. They don’t have to wait for the chef to cook one meal before they serve other tables.
Node.js is similar. The waiter is like a thread allocated to handle a request – this way a single thread can handle multiple requests.
In contrast to this, the synchronous and blocking nature, the same restaurant example would work a bit differently. While the waiter took the order from Table 1, he would wait in the kitchen while the chef prepared your order. He would not take any orders from the other tables in the restaurant.
In this case, to serve multiple requests, you need 1 thread for each request. Eventually, with a large number of requests coming in, you might run out of threads, and those requests will have to wait, while the other threads are just waiting without performing any task. More threads mean more hardware. This is not an efficient use of resources.
This is how a blocking and synchronous technology like ASP.net or Ruby on Rails works by default.
How does the Single Thread work with multiple requests in Node?
Say, Request 1 needs to query a database to get a result (any data). In this case, the thread will not wait while the database is being queried. It is free to serve Request 2….n.
When the result from the database is ready to be served, this is available in an Event Queue. The thread is continuously monitoring the Event Queue in the background. As soon as it finds an event in the Event Queue, it processes it.
This way the thread is capable of handling and serving multiple requests.
libuv is a multi-platform support library which is responsible for the phenomenal asynchronous I/O performance of Node.js.
Asynchronous and non-blocking nature of Node makes it ideal for I/O intensive apps. Node is hence ideal for apps which need a high amount of database, network or disk access.
According to the Node.js Foundation, Node surpassed a billion downloads and is now part of the three comma club. The core of Node.js is all about developing real-time applications.
According to The Battery Open-Source Software Index (BOSS Index), Node is the 4th most important open-source Project.
Internet of Things, Node.js has given all its competitors a run for their money.
There are a few major advantages of Node.js that make it so popular and widely used. Node.js is very efficient when it comes to web and enterprise applications that have a lot of input-output operations that query the database.
Every enterprise app starts small (MVP) and goes on to become a full-blown project which may define the business entirely. Enterprises are looking to get more Agile and have an iterative cycle for development. They’ve started developing applications with a Microservice architecture, where you build single-function modules that can function independently having a well-designed user-interface. This encourages the DevOps and Agile mentality within organizations.
With Microservice-based apps, Software is developed, tested and deployed faster and with higher reliability. Rather than having one big application with a complex codebase, organizations like Amazon, PayPal, GoDaddy and Netflix have opted for a Microservice-based architecture instead of a monolithic architecture. These companies build small units (microservices) that come together to form a large application. It allows developers to write code in different languages, for different parts of the app and from different parts of the world at the same time.
The single functioning modules can be decoupled and can troubleshoot easily.
Imagine there’s a modification to a small section of the codebase due to which the entire application needs to be deployed again. In case of a microservice-based application, the entire app does not have to be deployed again.
Node.js allows you to create highly scalable microservice-based web apps.
Regular Maintenance and Updating of Codebase
There’s a change in the users are consuming web and enterprise applications. Their needs are changing, and businesses need to evolve to adapt to their demands. UI/UX has become a significant part of an enterprise application. The way you represent action elements on an app, the way you collect data, the way you present data has had a significant shift. Less is more now, with the underlying factor that functionality is not compromised.
With Node.js this is quickly taken care of, and you can keep your clients happy by readily deploying their desired feature requests.
Increased Performance and Productivity
Due to Node.js’s asynchronous behaviour, it can handle a substantial volume requests simultaneously with minimal resources (hardware) at hand. This has a considerable impact on the response time of your web application. It also saves much cost on investing in expensive servers.
Node.js is based on JS. This makes it easier to maintain the frontend and backend of the application.
All-in-one Package Manager for all Project Dependencies
Node Package Manager (npm) is like the ace-in-the-hole for all Node.js developers. It consists of over 190,00 modules. It has been a key driving factor in the success of Node.js. Node.js has a massive number of third-party modules and libraries which are available through npm. This increases the usability of Node and reduces dependency. With npm, developers can use already available software modules and not write common features and functionalities from scratch.
As npm is open-source, it is under the microscope for many security issues. However, npm has an enterprise edition to counter that.
npm Enterprise lets businesses run the npm infrastructure behind their firewall. This gives businesses more control over the code to identify potential risks and vulnerabilities. They can fix these issues.
No Learning Curve
It also allows beginner-level developers to learn and implement Node.js for building web apps quickly.
With Node.js’ event-driven architecture, it offers a high level of concurrency. Node.js makes use of the event loop and callbacks. Callbacks are in place, and the thread does not have to wait till the request is served. Whenever the data is ready in the event loop, the thread processes and delivers it. This way your application can simultaneously handle a huge number of requests.
LTS (Long Term Support)
When everything around us is changing so fast, somethings need to stick. Node.js is only 10 years old but provides Long Term Support. This provides organizations and developers with the reliability which is required if you’re basing your entire business on a particular technology.
Any major Node.js release will be maintained for 18 months (as promised by Node.js) from the time it is made as an LTS version. Post this, it will enter a 12-month period of maintenance. Here, no new additions will be made to its modules (features) and existing bugs and security issues will be identified and fixed.

Encourages Cross-platform Collaboration
Node.js has a huge community built around it. The community consists of active developers who are continually adding value to the existing resources that Node has.
The Node.js foundation is a big step in the right direction. The foundation was formed in 2015, backed by the Linux Foundation and major players such as Fidelity, Microsoft, PayPal and so on. The foundation encourages developers to showcase their work.
In their words,
The Node.js Foundation’s mission is to enable widespread adoption and help accelerate the development of Node.js and other related modules.
Cross function development teams
As Node.js is based on JS, you don’t need to hire separate developers for backend and frontend. Quality developers working on Node, can work on Angular and React as well. Node.js pushes developers to become more efficient in both aspects of development, allowing enterprises to build a team which is more equipped to handle challenges. Full-stack developersare the future! As opposed to a skill-driven team of coders, testers, DevOps, and more, Node.js encourages developers to know it all. This reduces dependency and increases the productivity of the organization.
Node.js allows your application to scale vertically as well as horizontally. This means you can add additional nodes to the existing system. Also, you can add additional resources to your existing single nodes for the vertical uplifting of your app.
Some major companies have relied on Node.js as their primary technology for building apps and services. Some of these are:
PayPal compared its existing Java and Spring based application versus its newly developed Node App. It experienced that:
Dow Jones was already using JS in 2010. In 2011, they experimented with Node.js for building a Facebook-like application, named “Wall Street Journal Social”. The success was overwhelming. The Performance was phenomenal with just a few weeks of development time.
Soon after that, their CTO announced Node.js as their primary technology at Dow Jones.
NASA uses Node.js for a vital purpose – saving the lives of their astronauts in space!
Unfortunately, NASA came very close to losing one of their astronauts during a space expedition due to unreliable data being gathered from multiple locations.
NASA moved all of its data (for EVA Spacesuits) to a single cloud, reducing the access time.
Node.js has established itself as a major platform for backend services. It has become the Connor McGregor of web and enterprise-level app building technologies and rightly so.
The architecture for Node.js suits perfectly for many enterprise level applications which require high volumes of I/O operations with the Network, Disc or memory. Enterprise Apps such as Chat apps, Live Sports feed apps and more.
Node.js has a ton of benefits with faster time-to-market, lesser lines of code with higher performance. Serve MORE clients in LESS time with the same or lesser resources than a Java-based application.
With the LTS and community support built around it, Node.js is only going to grow from here.

Throughout the most recent couple of years, Node.js moved to backend development as well. Designers need to utilize a similar tech stack for the whole web project without learning another language for server-side development. Node.js is a device that adjusts JS usefulness and syntax to the backend.
Of late, organizations have been effectively changing from their backend tech stacks to Node.js. LinkedIn picked Node.js over Ruby on Rails since it took care of expanding responsibility better and decreased the quantity of servers by multiple times. PayPal and Netflix did something comparative, just they had a goal to change their design to microservices. We should investigate the motivations to pick Node.JS for web application development and when we are planning to hire node js developers.
Alongside prevalence, Node.js additionally acquired the fundamental JS benefits:
In addition, it’s a piece of a well known MEAN tech stack (the blend of MongoDB, Express.js, Angular, and Node.js — four tools that handle all vital parts of web application development).
In the event that you have JS designers in your group, it will be simpler for them to learn JS-based Node than a totally new dialect. What’s more, the front-end and back-end codebase will be basically the same, simple to peruse, and keep up — in light of the fact that they are both JS-based.
There’s another motivation behind why Node.js got famous so rapidly. The environment suits well the idea of microservice development (spilling stone monument usefulness into handfuls or many more modest administrations).
Microservices need to speak with one another rapidly — and Node.js is probably the quickest device in information handling. Among the fundamental Node.js benefits for programming development are its non-obstructing algorithms.
Node.js measures a few demands all at once without trusting that the first will be concluded. Many microservices can send messages to one another, and they will be gotten and addressed all the while.
Node.js was worked in view of adaptability — its name really says it. The environment permits numerous hubs to run all the while and speak with one another. Here’s the reason Node.js adaptability is better than other web backend development arrangements.
Node.js has a module that is liable for load adjusting for each running CPU center. This is one of numerous Node.js module benefits: you can run various hubs all at once, and the environment will naturally adjust the responsibility.
Node.js permits even apportioning: you can part your application into various situations. You show various forms of the application to different clients, in light of their age, interests, area, language, and so on. This builds personalization and diminishes responsibility. Hub accomplishes this with kid measures — tasks that rapidly speak with one another and share a similar root.
What’s more, Node’s non-hindering solicitation handling framework adds to fast, letting applications measure a great many solicitations.
Numerous designers consider nonconcurrent to be one of the two impediments and benefits of Node.js web application development. In Node, at whatever point the capacity is executed, the code consequently sends a callback. As the quantity of capacities develops, so does the number of callbacks — and you end up in a circumstance known as the callback damnation.
In any case, Node.js offers an exit plan. You can utilize systems that will plan capacities and sort through callbacks. Systems will associate comparable capacities consequently — so you can track down an essential component via search or in an envelope. At that point, there’s no compelling reason to look through callbacks.
So, these are some of the top benefits of Nodejs in web application development. This is how Nodejs is contributing a lot to the field of web application development.
