Socket.IO
Socket.IO is an event-driven library for real-time web applications. It enables real-time, bi-directional communication between web clients and servers. It consists of two components: a client, and a server. Both components have a nearly identical API. Socket.IO is also a protocol, where different complying implementations of the protocol can communicate with each other. The main implementation consists of two parts: a client that runs in the browser and a server for Node.js. Apart from the main implementation, there are multiple implementations, for example, the official Deno (JavaScript), C++, Java, Python, and Swift servers. Socket.IO primarily uses the WebSocket protocol with polling as a fallback option, while providing the same interface. Although it can be used simply as a wrapper for WebSockets, it provides many additional features such as heartbeats and timeouts. It can be installed with the npm (Node Package Manager).

Socket.IO is also a protocol,[4] where different complying implementations of the protocol can communicate with each other. The main implementation consists of two parts: a client that runs in the browser and a server for Node.js.
