Here's a snippet implementation for real-time messaging:

const { Server } = require("socket.io");

  const io = new Server(3000, {
    cors: { origin: "*" }
  });

  io.on("connection", (socket) => {
    socket.on("chat message", (msg) => {
      io.emit("chat message", {
        text: msg,
        user: socket.id,
        timestamp: new Date().toISOString()
      });
    });
    
    socket.on("disconnect", () => {
      console.log("User disconnected:", socket.id);
    });
  });
