MuteStates, CallViewModel and LocalMember reached the host through the
widget global. None of them are React components, so they take the bridge
as an explicit parameter: a constructor argument for MuteStates, a field
on CallViewModelOptions, and one on createLocalMembership$'s props.
src/state no longer refers to the widget API.
The conditionals around it mostly disappear: nullHostBridge's observables
are NEVER, so there is nothing to guard, and a request carries its own
reply rather than needing the transport and the original event.
CallViewModelWidget.test.ts drove hangup by emitting on the mocked
widget's action emitter, so it now injects a bridge instead, and checks
that the request is acknowledged.
The view models reached for getUrlParams() — and so window.location —
from deep inside the call path: CallViewModel, MediaDevices, Publisher,
LocalMember and the footer view model. An embedded Element Call has no URL
of its own, so these values have to arrive as arguments instead.
Add the relevant options to CallViewModelOptions, to the MediaDevices and
Publisher constructors, to createLocalMembership$ and enterRTCSession, and
to createCallFooterViewModel. The remaining React consumers read the
context added in the previous commit. AppViewModel now takes its audio
output options too, moving that URL read out to main.tsx, where the app
shell can act as the adapter.
The new CallViewModelOptions fields are optional, defaulting to what the
URL parameters resolve to outside widget mode; the MediaDevices and
Publisher arguments are required, so that every construction site has to
be explicit.
useTheme.test.ts mocked the UrlParams module with a factory, so it needed
updating to mock the hook rather than getUrlParams.
No functional change.
On mobile, the ringing status indicator is supposed to display in the header rather than on a tile. The exact layout differs between Android and iOS. To get it right I had to refactor AppBar to use CSS grid templates.
(Also, I changed my mind about the exact ringing data I needed out of CallViewModel - sorry. A little move of the ringtone audio renderer into its own component was necessary to accommodate that.)
I found our code's internal model of ringing a little overgrown (it had superfluous states like 'unknown') and difficult to extend with metadata or callbacks relating to ring attempts. By modeling ringing instead as a stream of ring attempts, where each attempt has an intent, a recipient, and an eventual outcome (accept/decline/timeout), I find it more natural to work with.
This makes room for a future 'try again' callback to allow ringing someone again after a timeout, and also forced me to look for a simpler solution to the duplicate leave sound effects. I exposed the intent of the ringing attempt to the call UI so I can later use it in the header.
The designs actually never want us to show the settings button in the footer if an app bar is in use (as in Element X mobile apps), so just avoid showing it at all in that case.
Because the type of header that we use in Element X (an 'app bar') lives in a different place in the document than the other headers, it needs a special branch to propagate the right insets.
