Top 8 Reasons To Use NodeJS In 2020

The most common programming language used for software development in many startups and large enterprises is Javascript. Ninety-five percent of websites use it as a client-side development tool. Javascript was used only in front-end development before 2009 and was used along with various server-side languages. It was surprising for developers about a decade ago (in 2009) when Ryan Dahl (the original developer of NodeJS) released the original version of NodeJS. Because they could not have imagined this language to be so powerful before, and it can also be used to write the code for the backend application. NodeJs is getting much well-deserved hype today, and many businesses, including Paypal, LinkedIn, Uber, Yahoo, Medium, GoDaddy, Groupon, Walmart, have shifted their tech stack to NodeJS.

In Silicon Valley, in particular, NodeJS is the world's hottest technology. Opening up fantastic career opportunities for any software developer is an excellent skill. It is beneficial for every programming language to use it, but what makes Node so unique? Why does it get so much hype from developers? What are some of its crisp features, and why do so many businesses use it for various applications? Let us talk about some reasons for learning about NodeJS in 2020.

1. Real-Time Applications

The web has become much more about communication today. Users want to communicate in real-time with one another. Chat, gaming, constant updates to social media, collaboration tools, websites for eCommerce, real-time tracking apps, marketplace-all of these features require real-time communication across the web between users, customers, and servers. It is challenging to build a real-time application because it takes place on a massive scale, supporting hundreds, thousands, even millions of users. Fast and continuous I / O is required for real-time communication between the client and the server.

For these sorts of applications, NodeJS is best suited. As events drive the architecture, the synchronization process with NodeJS is fast and organized, serving both the client-side and the server-side. The event loop handles the multiuser function through the web socket protocol. It works on TCP and prevents the overloading of HTTP. From a software development standpoint, NodeJS also makes RTA lightweight, scalable, sustainable, and usable.

2. Low Learning Curve

No matter what language you use for the backend application, you will still need JavaScript for the front-end. So you can spend all your efforts learning JS and mastering it instead of consuming your time teaching a server-side language such as Php, Java, or Ruby on Rails. On both the client-side and the server-side, Javascript can share the same language. So, without learning additional languages, a developer who knows JS can act as a full-stack dev. Because of the single language used on both sides, the front-end and backend are also simpler to keep in sync.

One of the significant benefits of getting their job done quickly with fewer developers is this for startups. For both parties, there is no need to divide the team. It offers greater productivity and the ability to share or reprocess the code and provides a smooth exchange of knowledge within the group.

3. Scalability and Performance

NodeJS is built on the Google-powered Chrome V8 engine. It enables Node to provide a runtime environment on the server-side, which compiles and executes JavaScript at lightning speeds. Instead of interpreting or running it as a bytecode, the V8 engine compiles JavaScript into native machine code, making Node fast. When contrasted to Java or C, lightweight Javascript achieves high performance with fewer lines of code. As Google advances to invest heavily in it, the Chrome V8 engine is also continually being updated.

The reason behind Javascript's rapid execution is its Event Loop. In a standard application server model that uses blocking I / O, the application must sequentially handle each request, suspending threads until they can be processed in this instance. This can add complexity to an app and, of course, slow down an app.

Node.js maintains an event loop for you that handles all asynchronous operations. It enables you to do non-blocking I / O in which threads can handle multiple requests (in this case, sequential, not concurrent). It is effectively 'withheld' as a promise if one can not be processed, which suggests it can be performed later without facing other threads. This whole process allows developers to use less memory and resources to handle a large number of operations.

Paypal, which used Node in their application, found that the application was built twice as fast with fewer people, with 33 percent fewer code lines and 40 percent fewer files. More importantly, the number of requests served per second has doubled, while the average response time has decreased by 35%. So Node is an excellent choice for the development of highly scalable apps.

4. Support for NPM With Rich Modules

Like NodeJS, only a few programming languages offer a rich package ecosystem. When you install Node.js, NPM (Node Package Manager) programs are automatically installed. Using the Node's official package manager, NPM, any Node.js developer can package their libraries and solutions into a module that anyone can install. Thousands of Javascript development libraries and tools are gathered on NPM. NPM centers on encouraging users to add new packages, with the constant support of the NodeJS community, so you have countless ready-made solutions for the specific issue.

It has over 60 K modules so far, and it is still growing every day. Is it not a good idea to use these modules for some standard features instead of writing the code from scratch? This great Node feature reduces the complexity, makes it easier to develop, and allows you to share easily, refresh, and even reuse the code.

5. Useful Single Codebase

Using the Node Data between server-side and client-side encoding is easy to send and synchronize. Your source code will be more transparent and consistent because of using the same Javascript language on both sides. You will use the same naming convention, the same tools, and the same best practices. Because of this function, the time of the developers is saved to a greater extent.

6. Data Streaming

Streams are collecting data, like Array in data structures, and it requires top-notch I / O data processing methods to handle this information. Node. Js comes to the rescue because it is good at handling such an I / O process that allows users to transcode media files while uploading them simultaneously. Compared with other data processing methods for processing data, it takes less time. Node.js streams help tremendously simplify I / O tasks.

In addition to the Pipe method for data handling, there are four types of streams used by node.js-Writable, Readable, Duplex, and Transform. When creating features such as processing files when they are uploaded, developers can take great advantage. NodeJS streams allow apps to consume less memory to work faster while dealing with massive amounts of data. This function gives the developer working on real-time audio or video encoding a more significant benefit.

7. Well Suited For Building Microservices

NodeJS is highly scalable and lightweight, as we have discussed, which is why its heavy microservice architecture favorite. Microservice architectures, in a nutshell, imply the breakdown of the application into isolated and independent services. As your services are decoupled, it makes it easier to update and retains the architecture. You can add up new or fix the existing architecture without dealing with the other applications' other parts. With the guidance of Node modules that represent NodeJS function building blocks, NodeJS improves well for designing such architectures. With this architecture, applications can be developed, managed, operated, and tested independently, saving you from the infrastructure's hazards. This feature enables code reusability between the client-side and the server-side, reducing the time and cost of development. You need to consider the introduction or update of new services.

8. Powerful Corporate Support

In 2015, several companies organized a NodeJS Foundation, including IBM, Microsoft, PayPal, Fidelity, SAP. It is an independent community aimed at facilitating the creation of core tools for NodeJS. The NodeJS foundation was created to accelerate the development of NodeJS and was intended to enable it to be widely adopted. The organizations that make use of Node.js in production are continuously developing. It includes nearly three hundred prominent companies, such as Medium, Uber.

Conclusion

The blessing for software programmers is Node.js, and it plays a vital role in the software stack. Building interactive games, chat programs, collaboration tools, instant messages, and much more is the first and foremost choice. We have just mentioned seven reasons, but apart from the above, you might find more. NodeJS has enormous support for the online community, allowing you to develop cross-platform apps, and if a company lacks its specialized proxy infrastructure, Node.js can serve as a proxy server. It is clear from the points mentioned above that Node.js is used for the startup or next enterprise projects for several reasons.
