Limit number of events by ip uniqueuserid or and socket id with rate limiter.
Socket io rooms limit.
Push data to clients that gets represented as real time counters charts or logs.
Within each namespace you can also define arbitrary channels called room that.

Although socket io indeed uses websocket as a transport when possible it adds additional metadata to each packet.
Socket io rooms within each namespace you can also define arbitrary channels that sockets can join and leave.
Socket io enables real time bidirectional and event based communication.
It works on every platform browser or device focusing equally on reliability and speed.
These channels are called rooms.
Any of the above examples specific to versions mentioned above you are querying the rooms property on socket io redis adapter.
Additonally if rooms list is temporary you can clean it whit controlled event after disconnecting.
A socket is the fundamental class for interacting with browser clients.

However the problems is that the connection is persistent and i wish to address the problem by using the socket leave room method.
In that case every socket in the room excluding the sender will get the event.
A socket belongs to a certain namespace by default and uses an underlying client to communicate.
When a user connects they automatically join the room that i have setup.
Socket io provides additional features over a plain websocket object which are listed below.
