fix: remove deprecated Vite customResolver usage - #670
Conversation
Keep Vite 8 and newer alias entries declarative and move Uniwind's internal React Native Web delegation into the plugin's pre resolveId hook. Preserve stylesheet interception first and normalize resolver paths for Windows. Constraint: Vite 8 deprecates resolve.alias[].customResolver and Vite 9 removes it Rejected: Drop the internal delegation | Uniwind internals would resolve react-native through the component alias Confidence: high Scope-risk: narrow Directive: Keep stylesheet resolution ahead of internal React Native Web delegation and preserve the Vite 7 resolver branch Tested: web 36 tests; native 171 tests; e2e 9 tests; typecheck, lint, type tests, dprint, package build, Vite 8.0.14 build, and Vite 7.2.2 build Not-tested: Vite 9 prerelease runtime is not available in this repository

| packages/uniwind/src/bundler/adapters/vite/vite.ts | Replaces the deprecated Vite 8 alias custom resolver with equivalent pre-plugin delegation while retaining stylesheet precedence and Vite 7 behavior. |
| packages/uniwind/tests/web/vite.test.ts | Adds resolver guard-condition tests and a real Vite plugin-pipeline regression test whose expected result is now resolved independently. |

Resolve an internal React Native import through Vite's real plugin container so the test covers alias rewriting and pre-plugin ordering together. Constraint: Hook-level tests bypass Vite alias sequencing Confidence: high Scope-risk: narrow Directive: Keep this test on the original react-native specifier so it exercises the complete resolver pipeline Tested: Vite adapter 7 tests; web 37 tests; test typecheck; dprint; Vite 8.0.14 example build

- Line 103: Strengthen the resolution assertion in the Vite test by comparing
resolved?.id with Vite’s direct resolution of react-native-web using the same
importer, or by asserting the exact expected module path; do not rely on
substring matching.

Compare the aliased React Native resolution with Vite's direct React Native Web resolution for the same importer so unrelated paths cannot satisfy the integration test.
