Fixes #85

Summary

Strips block and line comments from source code before evaluating fallback regex triggers (flushSync, silent, Store., etc.) in transformCompiledStoreModule.

Why

Previously, comments containing references like Store. (e.g., in JSDoc documentation) caused false positives, triggering an unnecessary fallback and skipping the CompiledStore transformation.

Changes

  • Removed comments (/* ... */ and // ...) prior to running the fallback pattern check in transform-store.ts.
  • Added regression tests in tests/closure-codegen/transform-store.test.ts to cover JSDoc comment scenarios.

Testing

  • Ran npm run test locally to ensure all existing and new tests pass.

Summary by CodeRabbit

  • Bug Fixes

    • Improved store code transformation when comments contain Store references.
    • Prevented comments, metadata, and string content from incorrectly triggering fallback behavior.
    • Improved handling of regular, optional, static, and string-adjacent store usage patterns.
    • Preserved correct transformation results while applying fallback only when necessary.
  • Tests

    • Added coverage for comments, optional and static store calls, and string literals containing comment-like text.
    • Added validation for transformed and fallback output in edge cases.

📝 Walkthrough

Walkthrough

The store transform replaces regex-based unsafe-pattern detection with AST traversal. The traversal ignores comments and metadata while detecting unsafe Store usage. Tests cover comment references, static calls, optional access, and string-literal edge cases.

Changes

Store transform handling

Layer / File(s) Summary
AST Store detection and validation
packages/vite-plugin-gea/src/closure-codegen/transform/transform-store.ts, packages/vite-plugin-gea/tests/closure-codegen/transform-store.test.ts
The transform detects unsafe identifiers, store member access, optional member access, and new Store usage through the parsed AST. Tests verify that comments do not block compilation and that unsafe calls use fallback behavior.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to ef2e2

The fallback detection change can misread string contents and optional Store access, potentially generating transformed code that omits required Store imports or behaves incorrectly at runtime. The PR is not merge-ready until these bounded correctness risks are addressed or explicitly accepted.

Add regression coverage for line comments and string literals.

This test covers only block/JSDoc comments. It does not cover the line-comment path or the case where // inside a string hides an executable Store.someMethod() call.

Add tests for both cases. Assert that comment-only input transforms and string-literal input falls back. Also strengthen the transformation assertion:

Suggested assertion
-    assert.match(result.code, /Compiled/)
+    assert.match(result.code, /extends Compiled(?:Lean)?Store/)

…ss in fallback check

- Add t.isOptionalMemberExpression check to hasUnsafeStorePattern to handle Store?.method()
- Add unit test to verify fallback behavior when optional store access is present
