NodeJS is the hottest technology across the world, especially in Silicon Valley. It is the perfect skill to open up amazing career opportunities for any software developer. Well, every programming language has some benefit of using it but what makes Node so special? why it is getting so much hype among developers? what are some of its cool features and why so many companies are using it for different kinds of applications? Let’s discuss some reasons to learn NodeJS in 2020…
1. Real-Time Applications
Today the web has become much more about interaction. Users want to interact with each other in real-time. Chat, gaming, constant social media updates, collaboration tools, eCommerce websites, real-time tracking apps, marketplace- each of these features requires real-time communication between users, clients, and servers across the web. Building a real-time application is challenging because it happens at a massive scale, supporting hundreds, thousands, even millions of users. The real-time communication between client and server requires fast and persistent I/O.
NodeJS is best suited for these kinds of applications. The synchronization process with NodeJS is fast and in an organized manner as events drive the architecture serves both the client-side and server-side. The event loop through the web socket protocol handles the multiuser function. It works in TCP and avoids HTTP overload. NodeJS also make RTA lightweight, scalable, maintainable, and usable from a software development standpoint.
2. Low Learning Curve
For startups, this is one of the big advantages to get their job done quickly with fewer developers. There is no need to divide the team for both sides. It provides higher productivity and the ability to share or reprocess the code and within the team offers a smooth exchange of knowledge.
3. Performance and Scalability
Node.js maintains an event loop that manages all asynchronous operations for you. It allows you to use non-blocking I/O in which threads (in this case sequential, not concurrent), which can manage multiple requests. If one can’t be processed, it’s effectively ‘withheld’ as a promise, which means it can be executed later without holding up other threads. This whole process allows developers to manage a large number of operations utilizing less memory and resources.
Paypal who used Node in their application found that the application was built twice as fast with fewer people, in 33% fewer lines of code and 40% fewer files. More importantly, they doubled the number of requests served per second while decreasing the average response time with 35%. So Node is an excellent choice for building highly scalable applications.
4. NPM Support With Rich Modules
Till now it has more than 60K modules and it’s still growing every day. Isn’t it a good idea to use these modules for some common features instead of writing the code from scratch? This great feature of Node reduces the complexity, makes the development simpler, faster and allows you to share, refresh and even reuse the code effortlessly.
5. Useful Single Codebase
6. Data Streaming
Just like Array in data structures, streams are the collection of data and to handle this data it requires top-notch I/O data processing methods. Node.Js comes to rescue since it’s good at handling such an I/O process which allows users to transcode media files simultaneously while they are being uploaded. It takes less time compared to other data processing methods for processing data. Node.js streams help simplify the I/O tasks tremendously.
There are four types of streams used by node.js- Writable, Readable, Duplex, and Transform, along with the Pipe method to handle data. The developers can take amazing advantage while forming features like processing files when they are uploaded. NodeJS streams enable apps to consume less memory while dealing with massive amounts of data to function faster. This feature gives more benefit to the developer working on real-time audio or video encoding.
7. Well Suited For Building Microservices
As we have discussed that NodeJS is highly scalable and lightweight that’s why its heavy favorite for microservice architectures. In a nutshell, microservice architectures mean breaking down the application into isolated and independent services. It makes it easier to update and maintain the architecture as your services are decoupled and you can add new or fix the existing architecture without dealing with the other parts of the applications. NodeJS fix well for designing such architectures with the help of Node modules which represent building blocks of NodeJS functions. With this architecture, applications can be independently developed, handled, operated, and tested, which saves you of the infrastructure risks. This feature allows code-reusability between client-side and server-side also it reduces the time and cost of development because you need only to consider new services introduced or updated.
8. Strong Corporate Support
In 2015 a number of companies including IBM, Microsoft, PayPal, Fidelity, SAP organized a NodeJS Foundation. It’s an independent community and aimed at facilitating the development of NodeJS core tools. The foundation NodeJS was formed to speed up the development of NodeJS, and it was intended to allow broad adoption of it. There is the continuous growth of the organizations that make use of Node.js in the production. Almost three hundred prominent companies like Medium, Uber, are included in it.
Node.js is the blessing for the software programmers and it plays a significant role in the technology stack. It is the first and foremost choice to build interactive games, chat programs, collaboration tools, instant messages, and much more. We just have mentioned 7 reasons but you could find more apart from the above. NodeJS has huge online community support, it allows you to develop cross-platform apps and if an enterprise lacks its specialized proxy infrastructure, then Node.js can serve as the proxy server. From the points mentioned above, it is clear that due to multiple reasons the Node.js is used for the startup or next enterprise projects.
