Emit help

[itsfuad]

I've gone through emit cheat sheet v3 and v4 but some things are not working properly. May be I misunderstood something.

For broadcasting an event to all clients in a room except sender, I used

socket.broadcast.emit('server_message', { text: `${name} joined the that🔥`, id: crypto.randomUUID() }, 'join');

But the message event is captured by every clients in every room and without room.

We have

io.to('room-name');

and

socket.to('room-name');

I need a clarification on rooms, all-clients, only-sender, except-sender, all-clients-in-room-[..], etc.

I'm using Deno as the server runtime

Hi!

Method	Description
io.emit()	to all connected clients
socket.broadcast.emit()	to all connected clients, except the sender
io.to("room1").emit()	to all connected clients in the room named "room1"
socket.to("room1").emit()	to all connected clients in the room named "room1", except the sender

Basically, rooms are filters that you apply when broadcasting an event.
