Change

Reuses media-query subscriptions across renders while retaining separate observers for each query and server-side rendering behavior.

Tests

The focused media-query subscription test passed. Type checks and lint passed.

Summary by CodeRabbit

• Bug Fixes
  • Improved media query updates by sharing subscriptions for identical queries and responding to browser changes.
  • Added a safe fallback for environments without browser APIs.

Walkthrough

useMediaQuery now reads from a cached store for each query. Browser stores use matchMedia and listen for changes. When window is unavailable, the hook uses a no-op subscription and a snapshot that returns false.

Changes: Media query store

Layer / File(s)	Summary
Store creation and hook integration resources/js/hooks/use-media-query.ts, tests/Unit/MediaQuery.test.tsx	The hook uses a cached store per query with a server fallback. Tests check that repeated calls reuse the store’s subscription and snapshot functions, and that subscribing and unsubscribing add and remove a listener.

Merge Risk: Minimal · previous review bf368

No merge-blocking issue was identified. Additional tests would strengthen coverage.

Security architecture risk: Minimal · up to bf368

The shared cache remains limited to browser media-query results. Existing consumers use fixed queries, listener cleanup is preserved, and normal server rendering bypasses the cache. No material security risk was identified in this change.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure is confined to browser-local media-query state and its UI consumers. Both located client callers pass fixed literals, so retained cache entries do not establish an attacker-amplifiable growth path in the inspected usage.

Trust Boundaries and Controls

• inferred — For normal server rendering without window, the early fallback prevents browser-store sharing across requests. This conclusion is conditional on that explicit environment check; behavior in a server environment that supplies a synthetic window is not established.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Test distinct media queries

23-47: Trivial · Functional Correctness · Quick win

Test distinct media queries

Add a second query and assert that it receives a separate subscription and snapshot. Keep the repeated-query assertions to preserve coverage for reuse.

Suggested fix

     assert.equal(useMediaQuery('(min-width: 800px)'), false);
     assert.equal(useMediaQuery('(min-width: 800px)'), false);
-    assert.equal(matchMedia.mock.calls.length, 1);
+    assert.equal(useMediaQuery('(max-width: 799px)'), false);
+    assert.equal(matchMedia.mock.calls.length, 2);
     assert.equal(calls[0].subscribe, calls[1].subscribe);
     assert.equal(calls[0].snapshot, calls[1].snapshot);
+    assert.notEqual(calls[0].subscribe, calls[2].subscribe);
+    assert.notEqual(calls[0].snapshot, calls[2].snapshot);

Review comment at @tests/Unit/MediaQuery.test.tsx around lines 23 - 47:
Extend the MediaQuery test to verify distinct queries receive independent
subscriptions and snapshots: call useMediaQuery with a second query, assert
matchMedia is called twice, and compare the corresponding entries in calls for
distinct subscribe and snapshot functions. Keep the repeated-query assertions to
preserve coverage for reuse.

Assert the event type in the matchMedia mock.

24-29: Trivial · Maintainability & Code Quality · Quick win

Assert the event type in the matchMedia mock.

The mock ignores the event type passed to addEventListener. The hook subscribes with 'change'. A regression that uses a different event name would still pass this test. Checking the type with the already imported assert closes that gap.

Suggested fix

-        addEventListener: (_type: string, listener: () => void) =>
-            listeners.add(listener),
+        addEventListener: (type: string, listener: () => void) => {
+            assert.equal(type, 'change');
+            listeners.add(listener);
+        },

Update the matchMedia mock’s addEventListener callback to assert with the
already imported assert that the event type is 'change' before registering the
listener; leave the listener tracking behavior unchanged.
