const express = require('express');
const http = require('http');
const socketIO = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = socketIO(server);

// Store the room data
const rooms = {};

io.on('connection', (socket) => {
  console.log('A user connected');

  socket.on('joinRoom', (roomNumber) => {
    // Join the specified room
    socket.join(roomNumber);
    console.log(`User joined room ${roomNumber}`);

    // Store the room information
    if (!rooms[roomNumber]) {
      rooms[roomNumber] = [];
    }
    rooms[roomNumber].push(socket.id);
  });

  socket.on('message', (data) => {
    console.log('Received message:', data);

    // Broadcast the message to all sockets in the same room
    const roomNumber = Object.keys(socket.rooms)[1];
    io.to(roomNumber).emit('message', data);
  });

  socket.on('disconnect', () => {
    console.log('A user disconnected');

    // Remove the socket from the room
    const roomNumber = Object.keys(socket.rooms)[1];
    if (rooms[roomNumber]) {
      rooms[roomNumber] = rooms[roomNumber].filter((id) => id !== socket.id);
      if (rooms[roomNumber].length === 0) {
        delete rooms[roomNumber];
      }
    }
  });
});

server.listen(3000, () => {
  console.log('Server listening on port 3000');
});
