fix: drop frozen listeners - #660
Conversation
📝 WalkthroughWalkthroughThe change replaces ChangesSnapshot synchronization
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This PR replaces React’s external-store subscription model with manual reducer and layout-effect synchronization for theme and CSS-variable state. Concurrent updates may produce stale or mixed derived props, and hydration may lack a stable server snapshot; merge should wait for this risk to be addressed or explicitly accepted. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Greptile SummaryThe PR replaces frozen external-store listeners with reducer-driven render snapshots and layout-effect subscriptions across Uniwind hooks and HOCs.
Confidence Score: 4/5The PR is not yet safe to merge because useCSSVariable can commit a CSS-variable snapshot invalidated between render and commit. The new render-time store read and layout-effect subscription no longer provide a pre-commit consistency check, allowing a concurrent theme or variable update to leave one committed render and its effects with stale data.

| Filename | Overview |
|---|---|
| packages/uniwind/src/hooks/useCSSVariable/useCSSVariable.ts | Fixes stale values when the requested variable changes, but the manual external-store read can commit a snapshot invalidated between render and commit. |
| packages/uniwind/src/hooks/useUniwind.ts | Introduces a shared reducer-and-layout-effect snapshot helper for theme and adaptive-theme state. |
| packages/uniwind/src/hoc/withUniwind.native.tsx | Replaces the native HOC external-store hook with reducer-driven dependency refreshes. |
| packages/uniwind/src/hoc/withUniwind.tsx | Replaces the web HOC external-store hook with reducer-driven class-name refreshes. |
| packages/uniwind/tests/native/components/scoped-variables.test.tsx | Adds coverage ensuring a changed variable name does not expose the previous variable during render. |

In `@packages/uniwind/src/hoc/withUniwind.native.tsx`:
- Around line 28-32: Replace the manual useReducer/useLayoutEffect snapshot
synchronization in both packages/uniwind/src/hoc/withUniwind.native.tsx (lines
28-32) and packages/uniwind/src/hooks/useCSSVariable/useCSSVariable.ts (lines
98-100) with useSyncExternalStore, using the existing UniwindListener
subscription and snapshot accessors so React rechecks external-store state
before commit. Update imports and preserve each hook’s current returned value
and behavior.
In `@packages/uniwind/src/hooks/useCSSVariable/useCSSVariable.ts`:
- Around line 96-100: Update the snapshot handling in the useCSSVariable hook so
a changed name immediately reconciles the current CSS variable value during
render rather than waiting for useLayoutEffect; preserve the existing rerender
behavior for later external changes. Add a regression test covering two variable
names with different values and verifying the value switches immediately when
name changes.
- Line 98: Replace the direct useLayoutEffect in the useCSSVariable hook with
the project’s SSR-safe isomorphic layout-effect wrapper, or migrate the
subscription to useSyncExternalStore with an appropriate server snapshot.
Preserve the hook’s existing client-side subscription behavior and dependencies.

- Around line 15-16: Replace the manual subscription logic in useSnapshot and
useClassNames with useSyncExternalStore, using consistent client snapshots and
stable server snapshots so concurrent renders and hydration remain coherent;
update the corresponding integration in packages/uniwind/src/hooks/useUniwind.ts
lines 15-16 and packages/uniwind/src/hoc/withUniwind.tsx lines 23-31, preserving
CSSListener’s client-side media-query initialization.
