Use cases for Node.js
Web and Mobile Applications
One of the most common use cases for Node.js is building web and mobile applications. Its ability to handle multiple concurrent requests and its large ecosystem of libraries and frameworks make it a popular choice for building APIs and other server-side components of modern web and mobile applications. For example, popular frameworks like Express and Hapi make it easy to create web servers and APIs, while tools like Socket.io and WebSockets enable real-time, bi-directional communication between clients and servers.
Real-Time Messaging and Collaboration Tools
Node.js is also commonly used for building real-time messaging and collaboration tools, such as chat applications, online gaming platforms, and virtual meeting and collaboration software. Its event-driven, non-blocking I/O model makes it well-suited for handling the high volumes of data and concurrent connections that are required for real-time applications.
