Repost from so but i need answers so here.
Socket io rooms not working.
Where you can save socket id or other identifier with rooms.
Each socket in socket io is identified by a random unguessable unique identifier socket id for your convenience each socket automatically joins a room identified by its own id.
In server code socket rooms is not an array that is a object.
Once again let me know if there s anything else you d like me to test or try and reproduce the issue.
Please use the classic socket emit instead.
Additonally if rooms list is temporary you can clean it whit controlled event after disconnecting.
These channels are called rooms.
After calling socket join and then listing the rooms the socket is in the socket is only connected to the room defined by it s id it s own room.
Rooms are used to further separate concerns.
Rooms also share the same socket connection like namespaces.
What socket io is not.
But first let s detail what the socket io library is not.
I have also tried reconfiguring my server to match the suggestions made by raghavgarg1257 and it still did not work either.
Steps to reproduce if the current behaviour is a bug async socketjoinroom socket.
In that case every socket in the room excluding the sender will get the event.
One thing to keep in mind while using rooms is that they can only.
Report a bug request a feature current behaviour after updating my socket io from 1 x to 2 1 1 my sockets are not joining any rooms anymore.
Socket io provides additional features over a plain websocket object which are listed below.
To add to this i have downgraded versions of socket io back to 1 5 0 and still getting the same issue.
Although socket io indeed uses websocket as a transport when possible it adds additional metadata to each packet.
Socket to socket id emit will not work as it will send to everyone in the room named socket id but the sender.
If you are using some db o nosql you can save it for distributed environments.
Within each namespace you can also define arbitrary channels that sockets can join and leave.
So my socket join calls are doing nothing.
When i use socket join xxx socket rooms can t be set.
I will get rooms with socket adapter rooms it s different to api doc.
