With the onset of digital solutions, there has been an ever-growing demand for different programming languages, frameworks, and other tech advancements. The companies were bound to make seamless frontend and backend tech integrations to engage users to one's platform. In this blog, we will witness one of the renowned backend technology- NodeJS, with its benefits and futuristic growth.
The truth prevails!! The backend foundation enhances the frontend of the software. Hence laying a strong backend advancement is a must for every business that wants to succeed in the digital arena.
Ryan Dahl invented NodeJS, the most exciting and powerful runtime environment for JavaScript. The backend technological advancement brought a revolution in the development of feature-rich web apps. According to a survey, NodeJS is more prevalent in terms of traffic than other backend servers.
The above-stated market analysis clarifies that businesses are turning to Node.js development services for fast, scalable, and robust web development.
JavaScript has earned a lot of popularity because of NodeJS. Now, what are the reasons for the NodeJS development popularity? Let's dive into them one by one.
Reasons for Using NodeJS
Since 2009, Node JS has constantly been evolving, and at present, it is topping the developer community charts with v16.9.0. With JavaScript running on the server-side, web apps have become extremely simple, cost-effective, and super efficient.
Here are some main reasons to use NodeJS as your server-side for successful application development.
- NodeJS is powered by Google Chrome's V8 engine, which helps initiate fast execution time and runs the web app quickly.
- The runtime environment is backed-up with over 50,000 package managers, allowing a developer to manage and save time by simply integrating the best functionality from the vast package bank.
- NodeJS is very useful in developing real-time and data-intensive web apps as it does not have to wait for an API to return the data.
- NodeJs speed up the loading time for audio and video files.
- Since NodeJs is open-source and merely a JavaScript framework, beginning the development of projects with it is pretty simple for developers already familiar with JavaScript.
NodeJS Server Architecture
NodeJS runs fast even when one functionality is incomplete through input/output bottlenecks. The approach is also addressed as input/output operations.
Non-blocking I/O and asynchronous request handling
NodeJS is asynchronous, which means it runs JavaScript in a single thread without waiting for a particular function to complete after fetching the data. The tech advancement will directly run the subsequent request while processing the I/O in the background. It is because of callbacks and promises.
While most programming languages are synchronous, they wait until the function receives data and works it out, blocking other operations. That is the reason for slow processing and poor user experience online.
Callbacks & Promises
Callbacks are functions called for I/O operations when completed, and add them to the event queue to serve it in the main thread once it’s clear. These callbacks are easily nested in other callbacks, leading to code complications called ‘callback hell.’ A promise is a new approach to handling async code. These are objects in functions that, rather than waiting to return value, make a promise to return later while other operations are executed. To keep this process running, Node has another functionality event loop.
Event Loop
The event loop successfully collects new callbacks and polls for incoming requests from the event queue. It helps in finishing the operation faster and then keeps on repeating the same process all over again.
Besides its famous architecture, NodeJS has many other benefits that help businesses flourish in the digital space. With the JavaScript language at its core, the cross-platform compatible advancement has instant garbage collection (GC) for a great memory, NPM accessibility, data processing ability, and a V8 engine to resolve every issue effectively.
Benefits of NodeJS App Development
- Robust Technological Stack
JavaScript has proven to be the most beneficial programming language and has a stand-alone name in the industry for providing the best app development services. NodeJS uses 2.1 percent of all websites, numbering itself atleast 30 million of them. A developer gets almost all the perks of full-stack JavaScript development, such as:-
- Enhanced effectiveness and development productivity
- Sharing and reusing of code
- Great speed and performance
- A huge number of free tools
Your web app solution tends to result in a faster and more reliable online venture. NodeJS facilitates the reusability of code, allowing frontend JavaScript to start the programming on the server side with minimum effort. With the same language used on the backend and frontend, it creates new levels of abstraction.
- Faster Web Task Processing
There is no doubt that NodeJS provides faster development services. With its V8 engine, NodeJS provides functions written in JavaScript into machine code to boost the overall performance and speed of the software.
Google has invested heavily in V8 and is improving it every year. As a result, NodeJS has come up with Non-blocking Input/Output and asynchronous request handling. Thus, a web solution with NodeJS has concurrent requests and single-threaded language development.
NodeJS has a very rare adaptability of web servers that allows heavy CPU-intensive tasks. As a result, leading companies like PayPal saw a 35 percent decrease in response time since migrating from Java.
- Scalable Microservice Architecture
The lightweight technology provides developers with microservice architecture. Instead of creating a single monolithic core, it breaks the application logic into smaller modules and microservices.
It enables better flexibility laying the foundation for further growth. In addition, the tech advancement easily adds more microservices to the existing ones to help integrate additional features with basic application functionality.
The best example that has implemented microservices and seen success on the user front is Walmart and GoDaddy. Walmart shifted to microservices and increased its conversion growth in general for its mobile application.
On the other hand, GoDaddy ran a whole Super Bowl ad campaign by handling 10,000 requests per second without downtime, using 10 percent of the hardware. NodeJS managed the requests without any digital hazard and connected with the audiences acquiring great engagement on its platform.
- NodeJS Libraries & Tools
NodeJS ecosystem consists of over 10,000 packages. As a result, 97 percent of modern web applications consist of NPM modules. With so many free tools available with only a few clicks, developers can make salient applications in no time.
Open-source software is becoming increasingly popular since it enables you to create innovative solutions while cutting overall development costs and time to market.
- Consistent JSON Support
Although other backend technologies like PHP and Ruby on Rails can communicate using the JSON format, Node.js employs JavaScript instead of translating between binary models.
It is especially useful for creating RESTful APIs to support NoSQL databases like MongoDB, represented by the letter M in the MEAN stack.
- Large Developer Community
According to StackOverflow developers survey, 42.12 percent of web engineers use NodeJS for their web apps. Such a following shows that the advancement has nailed the web development industry standard.
As a result, companies looking to hire Node.js developers won't likely experience a shortage of qualified candidates, and engineers can tackle any challenge imagined, thanks to a thriving and energetic ecosystem.
Conclusion
In conclusion, Node.js is a powerful and popular runtime environment for building scalable network applications. From a business's growth perspective, it provides fast and scalable architecture, ease of learning, large community, and cross-platform compatibility.
Amazon, Google, Facebook, and Netflix are the best examples that use NodeJS advantages massively. Overall, Node.js is a valuable tool for businesses looking to build efficient, high-performance applications that can handle many concurrent connections.
