Context
In Vue 2.0 the documentation and others clearly indicate that communication from parent to child happens via props.
Question
How does a parent tell its child an event has happened via props?
Should I just watch a prop called event? That doesn’t feel right, nor do alternatives ($emit/$on is for child to parent, and a hub model is for distant elements).
Example
I have a parent container and it needs to tell its child container that it’s okay to engage certain actions on an API. I need to be able to trigger functions.
