I've always been fascinated with technology and am happy to share Uptech’s experience with the IT community.
Node.js has more than 300 million downloads at the moment of writing, and there’s an active group of contributors driving the popular server-side runtime environment. If you’re wondering why it’s so popular with developers, here’s a list of advantages of using Node.js
Node.js offers Easy Scalability
Developing a server-side application can be tricky, particularly when it has to be scalable. Node.js uses a single thread to handle non-blocking I/O calls, which means that it’ll take fewer resources for the application to accept concurrent connections compared to traditional approaches.
With Node.js, you’ll have no problems scaling the application horizontally across multiple servers or vertically to increase its performance on a single server.
Node.js is used as a Single Programming Language
One of the benefits of using Node.js is its rich ecosystem. Building backend applications has never been easier with npm, a Node.js package installer that also doubles up as the marketplace.
Easy to Learn
The Advantage of Caching
Node.js can be optimized with caching services. Without a cache, the server application will have to execute the entire code and retrieve information from the database each time it processes a request.
A cache is a memory that stores the information during tun time. By using a cache, the server application returns the information from memory instead of executing the code to process subsequent requests.
There are various ways of caching in Node.js, and they all lead to a better experience for the end-users.
Offers the Freedom to Develop Apps
You’re not constrained to building back-end applications when you’re using Node.js. It can be coupled with frameworks like Electron and NW.js, which enable you to build cross-platform applications.
The notion of not having to learn native programming languages like C# and Objective C is why developers are choosing Node.js for development. Furthermore, you can use existing tools from Google Chrome Developer to test out the codes.
Getting Support for Commonly Used Tools
With Node.js, you have access to numerous tools that aid development and good support from the community. Have problems with real-time event communication using Socket.io? Raise it up in forums like StackOverflow, and you’ll receive help from your peers.
As Node.js is used by technological giants, the community that supports the environment will continue to grow.
Node.js is Highly Extensible
There’s more dynamics to Node.js than a typical backend application for simple websites. Node.js is highly extensible with its support of JSON format. Developers can use built-in API to use JSON for communication with other apps, clients, and servers on the network.
