sendToSpecificRoom(message: any): void {
if(message.roomName){
this.io.sockets.in(message.roomName).emit("eventSent", message);
}else{
this.io.sockets.emit("eventSent", message);
}
}
I need to send a message specifically to the sockets in a certain room. The "message" variable contains event data, including a property called roomName that I check to see if a room exists. How can I adjust the code above to achieve this?
Given that `rooms` is stored as a `Map`, the code `io.sockets.adapter.rooms["room name"]` will result in undefined. To fix this issue, I have substituted it with
io.sockets.adapter.rooms.get("room name")
Give this a shot:
if(io.sockets.adapter.rooms["room name"])
{
//check if the room exists
}
One way to tackle this is by utilizing a ternary operator to determine which entity should broadcast your message. Here's an example:
transmitMessageToUser(message: any): void {
const broadcaster = message.username ? this.sockets.in(message.username) : this.io.sockets;
broadcaster.emit("eventSent", message);
}
