react-rxjs is the library we've been using to connect our React components to view models and consume observables. However, after spending some time with react-rxjs, I feel that it's a very heavy-handed solution. It requires us to sprinkle <Subscribe /> and <RemoveSubscribe /> components all throughout the code, and makes React go through an extra render cycle whenever we mount a component that binds to a view model. What I really want is a lightweight React hook that just gets the current value out of a plain observable, without any extra setup. Luckily the observable-hooks library with its useObservableEagerState hook seems to do just that—and it's more actively maintained, too!
This turns on a lint rule to require display names for all of our components, which makes it a lot easier to find your way around the component tree in React's dev tools.
As Element Call grows in complexity, it has become a pain point that our business logic remains so tightly coupled to the UI code. In particular, this has made testing difficult, and the complex semantics of React hooks are not a great match for arbitrary business logic. Here, I show the beginnings of what it would look like for us to adopt the MVVM pattern. I've created a CallViewModel and TileViewModel that expose their state to the UI as rxjs Observables, as well as a couple of helper functions for consuming view models in React code.
This should contain no user-visible changes, but we need to watch out for regressions particularly around focus switching and promotion of speakers, because this was the logic I chose to refactor first.
...instead of monkey patching the console log objects. We use a logging
framework everywhere now (this fixes the times when we didn't...)
so there's not really a reason to do this the hacky way anymore.
This means that log lines now appear to come from whatever else is
intercepting the logger (eg. sentry) rather than rageshake.ts.
Opinions on this welcome on whether it's better or not.
This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
