Over the years, Node.js has become the go-to technology for building scalable web applications. It has gained enormous popularity amongst developers due to the many significant benefits it offers. With the support of an enthusiastic community, node.js is standing firm with a** 51.9% stake** as the most popular web framework, according to Stack Overflow’s 2020 Developer Survey.
Looking at the rising trend, we are debunking some of the top advantages which make Node.js a popular development choice in 2020.
Node.js Advantages:
Node.js Offers High-Performance for Real-time Applications
Web applications powered by Node.js benefit massively from its ability to multitask. Unlike other platforms, its single-threaded, event-driven architecture processes multiple concurrent requests efficiently without clogging the RAM. Moreover, its event-loop and non-blocking I/O operations allow code execution at a pace which significantly impacts the application’s overall performance.
What fuels Node.js with this superpower is that it’s built on Google Chrome’s V8 engine and written in C++. It breaks Javascript functions into machine codes with high efficiency and speed. It matters because Google invests heavily in its engine to improve performance, security, and provide excellent support for modern JavaScript features. Which directly impacts V8’s performance and, eventually, Node.js.
To ensure continuous advancements, Google has introduced the V8 benchmark suite to elevate Node.js’ performance with faster execution, better compilers, security patchworks, and ability to scale.
Node.js offers Easy Scalability for Modern Applications
With a consistently growing consumer base of tens of millions of users, titans like Netflix, Walmart, Uber, Paypal, among others, have regarded Node.js as a viable solution for scalability.
The cutting-edge technology comes with tons of features like the cluster module. It facilitates load balancing over multiple CPU cores, making it easy to deliver desired outcomes through smaller modules without burning out the RAM process. Additionally, Node.js employs a non-blocking event-loop mechanism with high scalability and enables the server to process requests seamlessly.
From the development standpoint, Node.js allows you to leverage Microservices that further lets you segregate your application into smaller parts. This way, you get to define tasks and allocate them efficiently among different teams to fast-track development, deployment, and maintenance of each division of your application. Node.js and Microservic allow modern applications to scale up and down as per need and help companies achieve high performance with fewer resources.
Walmart benefited enormously by replacing its former legacy system with the deadly combination– microservices architecture and Node.js. The retail giant saw an instant growth of 20% in overall conversions and a 98% boost in mobile conversion. What’s more, they end up saving 40% of the computing power, but they also cut costs by a whopping 20-50%.
