Improved Developer Experience (DX) by adding helpful links to the official Node.js release schedule in both README.md and src/types.ts.

  • Rationale: Developers often need to check why a version is LTS or EOL. Providing direct links saves them a search.
  • Changes:
    • src/types.ts: Added @see JSDoc tags to isLTS, ltsName, and isEOL properties pointing to the Node.js Release WG repository.
    • README.md: Updated the "NodeVersion Object" table to include markdown links in the description for isLTS and isEOL.
  • UX Impact: Improves the "discoverability" of information.
  • Accessibility: Improves the usefulness of IntelliSense tooltips in IDEs.

📝 Walkthrough

Walkthrough

This PR removes version string length constraints and simplifies version parsing logic by eliminating length checks and legacy tracking constants. It updates tests to validate the eolDate property and removes edge-case tests, while updating documentation and a minor dependency version range.

55-55: Remove MAX_VERSION_LENGTH concern; input validation is format-strict.

The code validates each version segment with /^\d+$/ (digits only, non-empty), which constrains input format strictly. While there is no explicit length limit on the overall input string, the regex validation on each segment effectively mitigates DoS concerns in practice. Real-world Node.js version strings are small (e.g., "20.10.15").

The removal of MAX_VERSION_LENGTH appears to be an intentional refactoring. If concerned about future maintenance, consider adding a test for large inputs, but this is not a security issue.

src/types.ts (1)

38-95: LGTM: Documentation improvements enhance developer experience.

The added @returns documentation for comparison methods and @see references to the official Node.js release schedule provide valuable context for developers. The links are authoritative and directly support the stated PR objectives.

Readme.md (1)

91-93: LGTM: API documentation now includes helpful reference links.

The inline links to the Node.js release schedule and EOL documentation improve discoverability and reduce friction when verifying LTS/EOL status, consistent with the PR objectives.

package.json (1)

66-66: Verify this dependency version range change is intentional.

The change from exact version "2.3.11" to caret range "^2.3.11" for the @biomejs/biome devDependency allows minor and patch updates. While this is a common practice, it's not mentioned in the PR objectives which focus on documentation improvements.

Please confirm this change is intentional and not an inadvertent modification.

src/index.test.ts (1)

319-331: Inconsistency: Functional tests added in a documentation-focused PR.

The PR objectives state this is focused on "improving developer experience by adding direct links to the official Node.js release schedule." However, these are new functional tests verifying the behavior of the eolDate property, not documentation changes.

Additionally, the AI summary mentions removal of MAX_VERSION_LENGTH and MIN_TRACKED_MAJOR constants and simplified parsing logic in src/index.ts, but src/index.ts is not included in this review.

This suggests either:

  1. Functional changes beyond documentation were made but not reflected in the PR description
  2. These tests are for functionality added in a previous commit
  3. The PR scope has expanded beyond its stated objectives

Please clarify whether functional changes to version parsing are included in this PR, and if so, update the PR description accordingly.

src/security.test.ts (1)

15-22: Inconsistency: Security fix tests in a documentation-focused PR.

The test description and comments explicitly reference "Before fix" and "After fix," indicating a security fix for handling multiple 'v' prefixes in version strings. This is a functional change, not a documentation improvement.

The PR title states "🎨 Palette: Improve docs with Node.js release schedule links" but this test update verifies security fixes to version parsing logic.

Please clarify:

  1. Are security fixes and functional changes intentionally included in this PR?
  2. Should the PR description be updated to reflect the broader scope?
  3. Is src/index.ts (where the parsing logic changes occurred) intentionally excluded from this review?
src/index.ts (4)

1-118: Flag: PR objectives inconsistency with actual changes.

The PR objectives state this PR is about "adding direct links to the official Node.js release schedule" in README.md and src/types.ts, but the actual changes in src/index.ts include significant logic modifications:

  • Removal of MAX_VERSION_LENGTH constant (inferred from line 55 change)
  • Removal of MIN_TRACKED_MAJOR constant (per AI summary)
  • Simplified version string parsing logic
  • Updated comparison methods

These are not documentation-only changes. Please verify:

  1. Is this the correct PR for the stated objectives?
  2. Should these logic changes be in a separate PR?
  3. Should the PR description be updated to reflect the actual changes?

33-42: LGTM: Excellent JSDoc additions.

The added documentation for getVersion is clear, comprehensive, and includes helpful examples. This will improve the developer experience through better IDE IntelliSense tooltips.


59-59: LGTM: Cleaner v-prefix handling.

The regex-based approach to strip the optional 'v' prefix is more concise and efficient than a loop-based implementation. The case-insensitive pattern correctly handles both 'v' and 'V' prefixes.


92-106: LGTM: Correct simplification of comparison methods.

The removal of explicit NaN checks is logically sound. Since compareTo returns NaN for invalid input, and JavaScript comparison operators with NaN always return false, the behavior remains identical while the code is more concise.
