Types Of Node.js Applications
Versatility is one of the reasons why Node.js is so popular. A single technology can be used to build dozens of applications, from simple to the most complex ones, making it the No.1 choice for many developers. Here are 15 popular types of Node.js applications, but be sure, it’s not even half of the list.
Single-Page Application
The most basic type of Node.js app is a single-page app. These web applications load a single HTML page and dynamically update the content as the user interacts with it. Node.js is particularly well-suited for building Single-Page Applications because it can handle a large number of asynchronous calls and heavy input/output (I/O) workloads faster and more efficiently. It makes it possible to create SPAs that provide a smooth and seamless user experience.
The event loop in Node.js is designed to allow for multiple concurrent client requests, which can be “delayed” until the necessary data is ready for processing. It enables Node.js to handle large amounts of data efficiently, ensuring that SPAs built with Node.js are both fast and responsive.
Real-Time Collaboration Tool
Another great example of Node.js web apps is a remote collaboration tool. Such tools are typically used by multiple users who need to work on a project simultaneously. Collaboration tools require a high level of real-time communication between users, such as sending messages, updating the status of tasks, or sharing files. Node.js is particularly well-suited for building such tools as it can handle multiple connections simultaneously without compromising performance. Besides, Node.js developers can use it with other real-time frameworks, such as WebSockets, to increase scalability and the number of simultaneous connections. Also, hire android developers to polish your projects.
