All the answers above and the one here socket io get rooms which socket is currently in or here socket io how do i get a list of connected sockets clients.
Socket io rooms list.
Were either incorrect or incomplete if you use 2 0.
These channels are called rooms.
To leave a channel you call leave in the same fashion as join both methods are asynchronous and accept a callback argument.
I m not sure where i m going wrong.
Rooms also share the same socket connection like namespaces.
Within each namespace you can also define arbitrary channels that sockets can join and leave.
Where you can save socket id or other identifier with rooms.
In that case every socket in the room excluding the sender will get the event.
I know i could keep my own list using an array but don t think this is an optimal solution for 2 reasons.
However it would be great to know about all the rooms without an ex.
A client library that loads on the browser side socket io client.
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 2 0 io sockets manager and io sockets clients don t exist anymore.
A server that integrates with or mounts on the node js http server socket io.
Here s a snippet of my code.
If you are using some db o nosql you can save it for distributed environments.
One thing to keep in mind while using rooms is.
For your convenience each socket automatically joins a room identified by its id see socket id.
I m trying to get a list of created rooms in an application by using io sockets adapter rooms.
Rooms are used to further separate concerns.
The mechanics of joining rooms are handled by the adapter that has been configured see server adapter above defaulting to socket io adapter.
In disconnect event you can query this object to know the rooms you have to leave.
I m trying to get a list of all the sockets clients that are currently connected.
During development socket io serves the client automatically for us as we ll see so for now we only have to install one module.
Additonally if rooms list is temporary you can clean it whit controlled event after disconnecting.
Socket io is composed of two parts.
Socket io already keeps a copy of this list.
Io sockets does not return an array unfortunately.
