Namespaces in Vue js events

Is it possible to have namespaces with events, like in JQuery?

like be able to do:

$.on('click.namespace')
$.on('change.namespace')
$.off('.namespace') // unregister both

No, and usually not needed in Vue:

When using @eventName="handler" in the template, Vue handles the registration and de-registration of the event handlers.

And because you can specify the name of the events a components $emits you won't have naming collisions.

To manually register & deregister an eventlistener when the component is destroyed:

emitter.$on(component.handleClick)
component.$on("$destroy", () => emitter.$off('click', component.handleClick))

Declare the handleClick in the methods: that creates a unique callback bound to the component.
