onConnect and onDisconnect hooks about server HOT 1 CLOSED

I agree! I have added OnConnect and OnDisconnect hooks. They have been merged and released as v1.0.5.

OnConnect

server.Events.OnConnect is called when a client successfully connects to the broker. The method receives the connect packet and the id and connection type for the client who connected.

import "github.com/mochi-co/mqtt/server/events"

server.Events.OnMessage = func(cl events.Client, pk events.Packet) (pkx events.Packet, err error) {
    fmt.Printf("<< OnConnect client connected %s: %+v\n", cl.ID, pk)
}

OnDisconnect

server.Events.OnDisconnect is called when a client disconnects to the broker. If the client disconnected abnormally, the reason is indicated in the err error parameter.

server.Events.OnDisconnect = func(cl events.Client, err error) {
    fmt.Printf("<< OnDisconnect client dicconnected %s: %v\n", cl.ID, err)
}
