what are all the known Rum starter templates?

what is ::handle

Okay I want to render 3 components in my app mounter.

How do I make an "all" component that can render all 3 without overwriting?

thanks

why do i need rum/local?

like i have a textarea...

clearly the submit button has to do something....

to do something there has to be an atom with the value and the :on-change ...

what's the idiomatic way? realize it's a newb q.
