clientId property
A client ID, used for identifying this client when publishing messages or for presence purposes.
The clientId can be any non-empty string, except it cannot contain a
*. This option is primarily intended to be used in situations where the
library is instantiated with a key. Note that a clientId may also be
implicit in a token used to instantiate the library. An error is raised if
a clientId specified here conflicts with the clientId implicit in the
token. Find out more about identified clients.
Implementation
