Every widget tap runs as its own headless task in the same JS runtime, and the tasks interleave at every await. Each one loaded the stored snapshot, edited it and saved it back, then refreshed from the server. That went wrong in three ways: - two taps loaded the same snapshot and the second save dropped the first change; - the refresh of the first tap read the server before the second tap's archive landed and was stored anyway, so the message came back (seen on the emulator with a slow `Email/set`); - a redraw of an older snapshot could land after a newer one, leaving buttons that act on a message the widget no longer shows. The snapshot now only holds what the server last said. A button's change is kept as a pending op next to it and laid over it when a widget draws; it stays until a refresh that started after the server took it has been stored (calendar and task changes only count as caught up by a refresh that loaded calendar and tasks). A call that fails drops its op, which also undoes an archive made offline: before, the failed refresh kept the edited snapshot and the message stayed hidden although it was never archived. Reads, writes and redraws of the widget data run one at a time, and every redraw draws the latest view.
Bulwark Mobile
Beta - work in progress. Many features are unfinished or rough. Expect bugs, missing functionality, and breaking changes between releases. Do not rely on this for primary email yet.
React Native (Expo SDK 54) client for Bulwark Webmail - a JMAP-based mail, calendar, and contacts app.
What works today
- Sign in to any JMAP server (e.g. Stalwart)
- Multiple accounts
- Email list, threads, compose
- Calendar (basic)
- Contacts (basic)
- Push notifications via the Bulwark relay - FCM by default, or UnifiedPush (e.g. ntfy) for devices without Google Play services
- Android: contacts and calendars sync both ways with the phone's Contacts and Calendar apps (Settings → Contacts / Calendar → Sync to this device)
- In-app sideload updates from GitHub Releases
What's missing or rough
- iOS builds, but push notifications, client certificates and syncing with the phone's contacts and calendars are Android-only so far
- S/MIME, plugins, themes - UI stubs only (filters & rules, the vacation responder and file storage are real implementations)
- Calendar editing is partial; contacts editing is basic
- No Play Store distribution yet (sideload APK from Releases); iOS ships via TestFlight
Run locally
npm install
npx expo start
Then press a for Android, i for iOS, or scan the QR with Expo Go.
For release APK builds and signing see docs/android-release.md. For iOS builds and TestFlight distribution see docs/ios-release.md.
