In reshaping careers as a developer or a programmer, node.js training has made its vitality across the industry. It is only because of the companies that highly rely on it or many companies switching their mobile apps from Ruby on Rails to Node.js in order to make it more flexible and time efficient. So, through this article, we are going to highlight the important working and features of Node.js with its applications in different fields. In addition, we have also suggested the best training institute from where you can give a directional path to your career. We are going to discuss some points throughout the article and they are-
- What is Node.js?
- Working of Node.js
- Features of the node.js
- What are the different applications of Node.js?
- Demerits of Node.js
- Tell me the different companies that use Node.js

What is nodeJS?
The introduction of NodeJS was made after 20 years of javascript which is one of the most famous programming languages among developers as millions of websites rely on javascript because it helps developers and designers to build various features for the web. If we talk about NodeJS then it is an open-source, single-threaded and cross-platform runtime environment which helps to build scalable server-side, fast and networking applications.
Working of Node.js
As I already told you, it is a single-threaded event loop which handles a number of clients at the same time. To understand it more clearly we must have prior knowledge of the multi-threaded event and multiple concurrent clients are handled in languages like Java.
In multi-threaded what happens is that every client sends a request and every request is processed by the server without responding back. However, these multiple threads are generally used to process concurrent calls and are defined in the thread pool. Whenever requests are received an individual thread is assigned to handle that.
Node.js works a little bit differently as it depends on a limited thread pool to provide requests; it means whenever a new request comes in, the node.js makes it in a queue. Whenever requests are being picked up by the loop it checks whether it requires a blocking input/output operation and if not then sends a response to the requests. After that, if the request is from any operation then the event loop assigns a thread from the internal thread pool. Limited internal threads are available; these are called worker groups. Once the blocking task is processed then, the event loop tracks the blocking request and puts them in the queue.
Node.js uses much fewer resources or memory to make it faster task execution.
Features of Node.Js
1- Easy to start– Node.js is very easy to start with and it is the best choice for developers as it comes with lots of tutorials and a large community so getting started in Node.js is quite easy.
2- Scalable– It has the capability of handling a number of simultaneous connections with high output because it is single-threaded and has vast scalability for applications.
3- Fast– Node.js becomes faster and more efficient by non-blocking thread execution.
4- Packages– to make our work much easier and simple it has a vast set of open-source Node.js and there is the availability of more than 10 lakh packages in the NPM ecosystem.
5- Strong backend– Since Node.js is written in Javascript, C and C++ it adds the feature in it of networking support which helps it to become more speedy.
6- Multi-platform– As we know that it is cross-platform support and it helps us to create multi-platform things such as websites, mobile applications and desktop applications.
7- Maintainable– it becomes quite easy for developers as javascript can manage both frontend and backend as a single language.
What are the different applications of Node.js?
There is a vast variety of applications in which Node.js is being used. Some of them which we are going to discuss here is-
1- Real-time chats– Being single-threaded asynchronous nature, it enhances the feature of the real-time chat process and also helps to build chatbots. It also adds features of multi-person chat and push notifications.
2- Data Streaming– One of the biggest companies in the world named Netflix uses Node.js for data streaming purposes as it is lightweight and fast, node.js provides it with the feature of native streaming API
3- Internet of Things– These applications are generally made up of multiple sensors because they constantly send small chunks of data that can be packed into a large number of requests.
Demerits of Node.js.
Everything in the world comes with merits and demerits too. So Node.js also has some demerits which we are going to discuss below.
1- Unsteady API
The API of node.js changes constantly and this change is often backward due to which a lack of consistency occurs. This is one of the biggest disadvantages of Node.js.
2- Time taken in the development
If you take Ruby as an example then it provides you with various directions from a fresh install and even guides you to start their way but in node.js you have to start everything from scratch.
Yes, definitely this can offer you flexibility but somehow it decreases productivity by slowing down the process of work. You can overcome this issue if you are cooperating with an experienced team of programmers or developers who has internally developed a process for maintaining and developing code.
3- Inappropriate for heavy-computing applications
As we have discussed above, node.js does not support multi-threaded programming but it has the capability of serving much more complicated applications than Ruby. But somewhere it is not good enough for performing long-running calculations.
Node.js is perfect for apps which are complex but when it comes to software which requires some heavy computing then it might perform less effectively. It is because weighted computations block the request which is coming which leads to a decrease in efficiency.
Tell me the different companies that use Node.js
Through the features of Node.js, we can take an idea of where it can be used. If not then don’t worry I am going to mention some of the companies that use Node.js.
1- NetFlix– I can’t think of anyone who doesn’t know about Netflix and why not it is the world’s leading provider of streaming media and video-on-demand. Netflix uses a huge amount of A/B testing to build a rich experience for its users as it is a data-driven platform.
2- LinkedIn– It is the world’s biggest business and employment-oriented service, firstly its mobile app highly relied on Ruby on Rails but then moved to Node.js and yes it makes it 2-10 times faster than its predecessor and extremely lightweight. This proved to be a smart move as the earlier app was quite immature in the runtime environment.
Apart from these two, there are many more companies which are moving their applications to Node.js to save time and make it faster.
Career-oriented training institute with placement guarantee.
To make a career in Node.js or any other field an established institute plays a significant role which provides you with a comfortable and answerable mentorship. If you ask me then I must suggest Aptron which is one of the best Node.js training institutes in Noida. Here you get trained under proficient and working professionals with 100% placement assistance.
