Walkthrough

A new utility function, compareNodes, was implemented to perform deep structural comparisons of AST nodes while ignoring non-semantic differences such as quote styles, semicolons, trailing commas, and metadata. The function was moved to a dedicated module, and comprehensive tests were added to verify its correctness in various scenarios.

Changes

File(s) Change Summary
.changeset/funny-lights-march.md Added a changeset describing the patch and improvements to compareNodes.
packages/ui/src/cli/commands/setup-init.ts Refactored to import compareNodes from a utility module instead of using a local implementation.
packages/ui/src/cli/utils/compare-nodes.ts Introduced the compareNodes utility for deep AST node comparison, ignoring non-semantic details.
packages/ui/src/cli/utils/compare-nodes.test.ts Added tests covering various edge cases for the compareNodes function.

Poem

In the warren where code does dwell,
A rabbit hops with tales to tell.
Comparing nodes with gentle care,
Ignores the quotes and commas there.
With tests that hop from case to case,
This patch brings order, style, and grace!
🐇✨

22-33: Consider adding type safety for the string literal check

The string literal normalization logic is correct but could benefit from stronger type checking to prevent runtime errors.

Consider this more type-safe approach:

  // Handle string literals specially - normalize quotes
  if (
-    "type" in a &&
-    "type" in b &&
+    typeof a === "object" && a !== null && "type" in a &&
+    typeof b === "object" && b !== null && "type" in b &&
    (a.type === "StringLiteral" || a.type === "Literal") &&
    (b.type === "StringLiteral" || b.type === "Literal") &&
    "value" in a &&
    "value" in b &&
    typeof a.value === "string" &&
    typeof b.value === "string"
  ) {
    return a.value === b.value;
  }

4-10: LGTM: Robust early return handling

The function correctly handles identity comparison and null/undefined cases, providing a solid foundation for the recursive comparison logic.


11-16: LGTM: Correct array comparison logic

The array handling properly checks type, length, and performs element-wise recursive comparison. The logic is sound and handles empty arrays correctly.


43-47: LGTM: Solid recursive object comparison

The object comparison logic correctly checks key count equality and recursively compares all properties. The type assertions are appropriate for this use case.


36-41: Filter covers all relevant AST metadata properties

A search across the codebase for common AST metadata keys (.source, .raw, .innerComments, .extra, etc.) returned no additional properties that need excluding. The existing filter—start, end, loc, range, tokens, comments, leadingComments, and trailingComments—is complete for our parser output.

.changeset/funny-lights-march.md (1)

1-12: LGTM: Clear and accurate changeset documentation

The changeset properly describes the patch-level improvements to compareNodes functionality and includes mention of the added test coverage.

packages/ui/src/cli/commands/setup-init.ts (1)

4-4: LGTM: Clean refactoring to use centralized utility

The extraction of compareNodes to a dedicated utility module improves code organization and reusability. The import is correctly placed and follows TypeScript conventions.

packages/ui/src/cli/utils/compare-nodes.test.ts (5)

5-13: LGTM: Comprehensive basic equality tests

The basic equality tests cover all primitive types and edge cases including null/undefined comparisons and type mismatches.


22-26: LGTM: Core functionality test for quote normalization

This test directly validates the key feature of the PR - treating different quote styles as equivalent in string literals.


72-78: Excellent edge case coverage for template literals

Good test ensuring template literals are correctly treated as different from regular string literals, maintaining semantic accuracy.


100-120: Thorough semicolon handling verification

The tests comprehensively cover semicolon presence/absence across different JavaScript constructs - variable declarations, multiple statements, objects, and functions.


122-179: Comprehensive trailing comma test coverage

Excellent coverage of trailing commas in various contexts: single-line vs multi-line objects/arrays, and nested structures. This thoroughly validates the PR's key functionality.
