Proposed changes

Resolves an issue where tapping a channel push notification or deep link on Android fails to navigate to the target room when the socket is disconnected or when transitioning from background to foreground.

  • Local-First Resolution: Resolves room from WatermelonDB (findSubscriptionByName, findSubscriptionByRid) in canOpenRoom before falling back to REST calls.
  • Socket Recovery Retry: In deepLinking.js, attempts recoverSocket and retries canOpenRoom if initial resolution fails on a dormant connection.
  • Foreground Lifecycle Sequencing: In state.js, converted detached promises in appHasComeBackToForeground to sequential yield call(...) effects with error handling.

Issue(s)

N/A

How to test or reproduce

  1. On Android, background the app and ensure the WebSocket connection is idle or disconnected.
  2. Receive a push notification for a channel or private group the user belongs to.
  3. Tap the notification from the system tray.
  4. Expected: App foregrounds, reconnects socket, resolves room from local subscriptions, and navigates directly into the chat room.

Note / AI Disclosure: This fix was developed with AI. I did reproduce the issue beforehand, and then ran the new build for a week to verify it on my personal Android phone, with a stubbed notification relay proxy.

Summary by CodeRabbit

  • Bug Fixes
    • Improved room deep linking by resolving rooms through identifiers, names, or paths.
    • Added automatic connection recovery and retry when opening a room fails.
    • Improved reliability when opening rooms after temporary connection interruptions.
    • Prevented unnecessary subscription lookups when local subscription data is unavailable.
    • Improved app return-from-background handling by completing connection recovery and pending notification checks before continuing navigation.

Walkthrough

The change adds typed local subscription resolution, a rid fallback for unresolved rooms, socket recovery and retry during deep-link navigation, and awaited foreground recovery effects.

Changes

Deep-link room recovery

Layer / File(s) Summary
Typed local room resolution
app/lib/methods/canOpenRoom.ts, app/lib/methods/canOpenRoom.test.ts
canOpenRoom now exposes typed room results and subscription helpers. It resolves local rooms by ID or channel name, normalizes asPlain() models, and returns { rid } when no path resolution succeeds.
Deep-link retry after socket recovery
app/sagas/deepLinking.js, app/sagas/__tests__/deepLinking.test.ts
The navigation saga calls recoverSocket and retries canOpenRoom when the initial lookup fails. The test verifies recovery, retry, and one navigation.
Foreground recovery sequencing
app/sagas/state.js
The foreground saga awaits recoverSocket and checkPendingNotification with yield call(...), using separate error handling.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 4f86d

Private-group deep links may still fail to open the target room when the room is resolved locally, leaving the Android navigation fix incomplete. Merge should wait for this behavior to be corrected or explicitly accepted by the owner.

Replace the untyped room contracts.

any propagates from formatRoom through both subscription lookup helpers and canOpenRoom, so TypeScript cannot validate values from db.get('subscriptions') or the room returned by open. Define interfaces for the serialized subscription and collection operations. Add explicit parameter and return types, including the concrete room union plus false for canOpenRoom.

159-160: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Open locally resolved private groups before navigation.

If a matching local subscription has t === 'p', these returns bypass open(). They also bypass openGroup(), although Line 63 states that a group must be open before it can be read. A deep link to a cached closed private group can therefore still fail after this fast path is enabled.

Call openGroup(room.rid) before returning a local private-group result. Treat its existing “already open” result as success. Add a regression case for a locally resolved private group.

18-18: Complete the room result type conversion.

[key: string]: any, | any, and | boolean keep this contract unbounded. The function has no successful true return path. Define the complete result shape and use false as the failure member so database values and callers remain type-checked.

Run the repository typecheck after the update. As per coding guidelines, use TypeScript for type safety and add explicit type annotations.
