25-32: Improve format documentation clarityThe comments showing HTML format examples use a future date (2024). Consider:
- Using actual dates from nodejs.org
- Structuring the comments to clearly separate old vs new formats
- Adding JSDoc-style documentation explaining the format differences
37-42: LGTM! Consider adding type annotationThe directory handling logic is correct. The use of
basenameproperly handles both relative and absolute paths.Consider adding a type annotation for clarity:
- let name = m[1]; + let name: string = m[1];
42-46: Consider parsing size values with unitsThe size handling could be improved to parse values with units (KB, B) into a standardized format.
Consider adding a helper function:
function parseSize(sizeStr: string): number | null { if (sizeStr === '-') return null; const match = sizeStr.trim().match(/^([\d.]+)\s*([KMG]B|B)?$/i); if (!match) return null; const [, value, unit] = match; const baseValue = parseFloat(value); const multipliers = { B: 1, KB: 1024, MB: 1024 * 1024, GB: 1024 * 1024 * 1024 }; return baseValue * (unit ? multipliers[unit.toUpperCase()] : 1); }test/common/adapter/binary/NodeBinary.test.ts (1)
87-103: Maintain consistent assertion style across testsThe new test uses
assert.equal()while other tests use theassert()with direct comparison. Consider updating the assertions to match the existing style for consistency:- assert.equal(item.date, '-'); - assert.equal(item.isDir, true); - assert.equal(item.size, '-'); + assert(item.date === '-'); + assert(item.isDir === true); + assert(item.size === '-');

49-57: LGTM! Clean implementation
The item construction is well-structured and properly handles optional configuration.
33-33: Verify regex pattern robustness
The regex pattern handles both old and new formats, but let's verify it handles all edge cases correctly.
✅ Verification successful
Regex pattern is correctly handling all edge cases
The regex pattern has been thoroughly verified through the test cases which cover:
- Both old and new HTML formats from nodejs.org
- Directory entries with "-" size and various date formats
- File entries with different size formats (e.g., "3.2 KB", "20416228")
- Various date formats including "-" and "DD-MMM-YYYY HH:MM"
- Both relative ("/dist/v18.15.0/file") and direct ("file") href formats
- Zero-size file exclusion
The test suite demonstrates the pattern successfully parses:
- Root directory listings
- Version subdirectories (v16, v18)
- Nightly build directories
- Different file types (docs, binaries, checksums)

💡 Codebase verification
Test fixtures contain future dates that need updating
The future dates are coming from the test fixtures file (test/fixtures/nodejs.org/site/v18.15.0/index.html). These dates are used to mock HTTP responses in tests. While the tests will pass today, they will start failing when we reach and pass these dates (October/November 2024).
Recommendations:
- Update the fixture file to use past dates (e.g., March 2023)
- Update the corresponding test assertions in
NodeBinary.test.ts - Consider using relative dates or date mocking utilities for more maintainable tests
🔗 Analysis chain
Verify test dates: Future dates detected
The test uses dates from November and October 2024, which are in the future. This could cause test failures when these dates become past dates. Consider:
- Verifying if these dates are correct
- Using past dates for more reliable testing
- Using date assertions that are resilient to time passage

🛠️ Refactor suggestion
Test coverage for size format parsing is essential
Based on the implementation and test fixtures, the review comment is valid. The NodeBinary implementation directly uses the size string from the HTML without proper parsing or validation, while the test now expects formatted sizes ("3.2 KB", "29 MB"). This change needs proper test coverage as:
- The implementation in
NodeBinary.tssimply usesm[3].trim()without any size format parsing - The nodejs.org fixture shows various size formats (B, KB, MB) that need to be handled
- Current tests don't verify edge cases in size parsing
Key areas needing test coverage:
- Various size units (B, KB, MB, GB)
- Decimal places handling (e.g., "3.2 KB", "8.6 MB")
- Edge cases (e.g., "478 KB", "310 B")
- Invalid formats
🔗 Analysis chain
Add test coverage for size format parsing
The test introduces human-readable sizes ("3.2 KB", "29 MB") while other tests use byte counts. This suggests a change in the NodeBinary.fetch() implementation to handle formatted sizes. Consider adding test cases for:
- Edge cases in size formatting (e.g., "1.0 KB", "0.9 MB")
- Various size units (B, KB, MB, GB)
- Invalid size formats
