According to the official documentation, to send a message to a specific room you can use the example below:

//enviando para todos na sala (room) 'game', com exceção do remetente
socket.to('game').emit('nice game', "let's play a game");

// enviando para todos na sala (room) 'game', incluindo o remetente
io.in('game').emit('big-announcement', 'the game will start soon');
