A Newbie's Guide to The Composable Architecture
summary
Live-coding builds a Pomodoro app with The Composable Architecture: defines State/Action/Reducer, a Store and ViewStore, runs a one-second timer via continuous clock effects and stops it with cancelable effects, scopes a modal child with presentation state and identified array, injects dependencies (clock, UUID, date) so tests use a test clock and deterministic UUID/date, and proves behavior with TestStore assertions — timers append on stop, cancellation works, and unit tests pass without waiting.
