Socket.io is a JavaScript library for real-time web applications. It enables real-time, bidirectional, and event-based communication between web clients and servers. Socket.io consists of two parts:

• A server-side library for Node.js
• A client-side library that runs in the browser

• Connection: Establishes a connection between the client and server.
• Events: Named messages sent between the client and server.
• Broadcasting: Sending a message to multiple clients.

In the server code:

io.on("connection", (socket) => {
    socket.on("user-message", (data) => {
        socket.broadcast.emit("message", data);
    });
});
