Problem

A chat dock in another tab can retain stale state after local storage is cleared.

Change

Handles local-storage clear events while ignoring events from other storage areas and preserving the existing per-key update behavior.

Tests

The focused chat dock storage test passed. Type checks and lint passed.

Summary by CodeRabbit

  • Bug Fixes
    • Chat dock state now remains unchanged when storage updates come from a different storage area. Clearing local storage still resets the dock to its default state and updates the display, preventing unrelated storage activity from causing unexpected dock changes.

Walkthrough

The chat dock storage listener now ignores events from storage areas other than window.localStorage. It handles events for the chat-dock key or a null key. A unit test checks event filtering, dock state, notifications, and listener cleanup.

Changes: Chat dock storage events

Layer / File(s) Summary
Storage event handling and validation
resources/js/lib/chat-dock.ts, tests/Unit/ChatDockStorage.test.tsx
The listener checks the storage area and accepts events for the chat-dock key or a null key. The test checks that other storage areas do not change dock state or notify subscribers, while a null-key event from local storage resets the state and notifies subscribers. It also checks listener cleanup.

The dock change has limited automated coverage: CI skips the new test, and per-key updates are untested. Address these gaps as a bounded follow-up.

Full details: Title check

Explanation

The title "fix: sync the chat dock when another tab clears storage" matches the main change. The storage listener in resources/js/lib/chat-dock.ts now ignores events from storage areas other than window.localStorage. It resets the cached dock state and notifies listeners on local-storage events where the key is chat-dock or null, so a clear from another tab syncs the dock. The added unit test covers the null-key case from a different storage area and from local storage. The title is specific and concise, and it names the primary behavior change.

Nitpick Cover the per-key chat-dock storage event in this test.

24-65: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Cover the per-key chat-dock storage event in this test.

The test sends only key: null events. The key === 'chat-dock' branch in resources/js/lib/chat-dock.ts is not exercised. A regression in that branch that stops state refresh or subscriber notification would still pass this test. The notification counts across the steps should run 0, then 1, then 2.

Suggested fix
     onStorage?.({ key: null, storageArea: {} });
     assert.equal(notify.mock.calls.length, 0);
     assert.equal(useChatDock().isDocked, true);
 
+    values.set('chat-dock', JSON.stringify({
+        isDocked: true,
+        isExpanded: false,
+        conversation: 'bob',
+    }));
+    onStorage?.({ key: 'chat-dock', storageArea: localStorage });
+    assert.equal(notify.mock.calls.length, 1);
+    assert.equal(useChatDock().conversation, 'bob');
+
     values.clear();
     onStorage?.({ key: null, storageArea: localStorage });
 
-    assert.equal(notify.mock.calls.length, 1);
+    assert.equal(notify.mock.calls.length, 2);

Review comment at @tests/Unit/ChatDockStorage.test.tsx around lines 24 - 65:
Update the “clears the dock when another tab wipes local storage” test to
exercise the per-key `chat-dock` storage event: change the stored state,
dispatch that event, and assert the subscriber is notified and `useChatDock()`
reflects the updated state. Then preserve the existing clear-event assertions,
updating notification counts to 0, then 1, then 2.

Run this test in the unit workflow.

test:unit runs Node tests matching tests/Unit/*.test.ts, so it excludes this .tsx file. The frontend CI job therefore does not run this regression test. Add a Vite test invocation to the workflow, or port the test to the existing runner. Renaming the file alone will not make the runners compatible. (raw.githubusercontent.com)

Review comment at @tests/Unit/ChatDockStorage.test.tsx at line 4:
Ensure ChatDockStorage.test.tsx is executed by the frontend CI unit workflow:
add a Vite test invocation compatible with its vite-plus/test imports, or port
the regression test to the existing test:unit runner with compatible APIs;
renaming the file alone is insufficient.
