To leave a channel you call leave in the same fashion as join both methods are asynchronous and accept a callback argument.
Socket io rooms limit.
Although socket io indeed uses websocket as a transport when possible it adds additional metadata to each packet.
But first let s detail what the socket io library is not.
Prevent flooding from single connection.
Socket io is not a websocket implementation.
It should be noted the socket doesn t relate directly to the actual underlying tcp ip socket and it is only the name of the class.
In that case every socket in the room excluding the sender will get the event.
A socket is the fundamental class for interacting with browser clients.
Limit number of events by ip uniqueuserid or and socket id with rate limiter.
Can i use wildcards in events.
Push data to clients that gets represented as real time counters charts or logs.
What socket io is not.
However the problems is that the connection is persistent and i wish to address the problem by using the socket leave room method.
Additonally if rooms list is temporary you can clean it whit controlled event after disconnecting.
Where you can save socket id or other identifier with rooms.
Socket io enables real time bidirectional and event based communication.
It provides a socket io middleware to deal with wildcards.
Any of the above examples specific to versions mentioned above you are querying the rooms property on socket io redis adapter.
I have a problem regarding the handling of multiple chat rooms.
Within each namespace you can also define arbitrary channels called room that.
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.
Socket io rooms within each namespace you can also define arbitrary channels that sockets can join and leave.
These channels are called rooms.
If you are using some db o nosql you can save it for distributed environments.
In disconnect event you can query this object to know the rooms you have to leave.
This wasn t overridden by the redis adapter so you re actually querying the base adapter which only knows about rooms clients in the current process.
Socket io provides additional features over a plain websocket object which are listed below.
A socket belongs to a certain namespace by default and uses an underlying client to communicate.
It works on every platform browser or device focusing equally on reliability and speed.
My question is how can this be handled on the client side.
