10-10: Clarify test coverage discrepancy.There's an inconsistency in the reported test coverage:
- Line 10: Badge shows "coverage-97.9%"
- Line 96: Text shows "84.9% code coverage"
Also, the integration tests show 66/67 passing (98.5%). Please verify:
- Which coverage metric is correct?
- Is the 1 failing integration test expected/acceptable?
Also applies to: 94-96
🧹 Nitpick comments (7)
packages/core/src/math/figma-squircle.ts (1)
282-296: Consider clamping negative inset values.The function doesn't handle negative
insetvalues explicitly. If a negative inset is passed, the path would expand outward (larger than original dimensions), which may lead to unexpected behavior.export function generateFigmaSquirclePathWithInset( width: number, height: number, radius: number, smoothing: number, inset: number ): string { + // Ensure inset is non-negative + const safeInset = Math.max(0, inset); + // Adjust dimensions for inset - const w = width - inset * 2; - const h = height - inset * 2; + const w = width - safeInset * 2; + const h = height - safeInset * 2;packages/core/src/utils/data-attributes.ts (1)
239-244: Consider warning when border width is specified without color.When
data-squircle-border-widthis set withoutdata-squircle-border-color, the border is silently ignored. A development warning would help users understand why their border isn't appearing.} else if (borderWidth !== undefined && borderColor === undefined) { // Width without color - don't create border config // This matches the behavior where color is required // Note: Per spec research.md section 10, gradient borders require JavaScript API + if (process.env.NODE_ENV === 'development') { + warn(`data-squircle-border-width specified without data-squircle-border-color. Border requires a color to be rendered.`, { + element: element.tagName, + id: element.id || undefined, + className: element.className || undefined, + }); + } }packages/core/tests/integration/border-visual.test.ts (2)
329-331: Consider usingwaitForFunctioninstead of fixed timeouts.Multiple tests use
page.waitForTimeout(100)orpage.waitForTimeout(150)which can lead to flaky tests on slower CI environments. Consider using Playwright'swaitForFunctionto wait for a specific condition instead.Example for the resize test:
- await page.waitForTimeout(150); + await page.waitForFunction(() => { + const svg = document.querySelector('#solid-border-element svg.cornerkit-border'); + return svg?.getAttribute('viewBox')?.includes('300'); + }, { timeout: 2000 });Also applies to: 372-372, 423-423, 577-578, 614-614, 642-642, 669-669, 705-705
452-475: Type the caught error properly.The error variable in the catch block is typed as
anyimplicitly. Consider using explicit error typing for better type safety.} catch (e) { - return { success: false, error: e.message }; + return { success: false, error: (e as Error).message }; }website/index.html (1)
958-960: Cache-busting query parameters for development.The script tags include cache-busting query params (
?v=20251207-gradient-fix). This is fine for development, but ensure these are removed or automated in production builds to leverage browser caching properly.Consider using a build process to inject version hashes automatically rather than manual date strings:
- <script src="cornerkit.js?v=20251207-gradient-fix"></script> - <script src="app.js?v=20251207-gradient-fix"></script> + <script src="cornerkit.js"></script> + <script src="app.js"></script>packages/core/src/renderers/clippath.ts (2)
196-196: Minor condition inconsistency withshouldSkipBorder.The condition here checks
border.gradient.length >= 2, butshouldSkipBorderinborder.tschecksborder.gradient.length === 0. When gradient has exactly 1 stop, this condition passes butcreateBorderSVGwill warn and fall back to solid color. The behavior is correct, but the validation is split across files.Consider aligning the validation or documenting that 1-stop gradients are handled as fallback cases.
272-325: Extract duplicated restoration logic into a helper method.The style restoration logic (lines 272-325) is nearly identical to the code in
remove()(lines 112-165). Both restore background, background-image, box-shadow, position, and isolation, then clean up data attributes.Consider extracting this into a private helper method to reduce duplication and ensure consistent behavior.
+ /** + * Restores original styles captured before border rendering + * @param element - Target HTMLElement + */ + private restoreOriginalStyles(element: HTMLElement): void { + // Restore original background color + const originalBg = element.dataset['squircleOriginalBg']; + const hadInlineBg = element.dataset['squircleHadInlineBg'] === 'true'; + if (originalBg !== undefined) { + if (hadInlineBg) { + element.style.backgroundColor = originalBg; + } else { + element.style.removeProperty('background-color'); + } + } + + // Restore original background-image + const originalBgImage = element.dataset['squircleOriginalBgImage']; + const hadInlineBgImage = element.dataset['squircleHadInlineBgImage'] === 'true'; + if (originalBgImage !== undefined) { + if (hadInlineBgImage) { + element.style.backgroundImage = originalBgImage; + } else { + element.style.removeProperty('background-image'); + } + } + + // Restore original box-shadow + const originalShadow = element.dataset['squircleOriginalShadow']; + const hadInlineShadow = element.dataset['squircleHadInlineShadow'] === 'true'; + if (originalShadow !== undefined) { + if (hadInlineShadow) { + element.style.boxShadow = originalShadow; + } else { + element.style.removeProperty('box-shadow'); + } + } + + // Restore position if we set it + if (element.dataset['squircleSetPosition'] === 'true') { + element.style.position = ''; + delete element.dataset['squircleSetPosition']; + } + + // Remove isolation context + element.style.isolation = ''; + + // Clean up data attributes + delete element.dataset['squircleOriginalBg']; + delete element.dataset['squircleHadInlineBg']; + delete element.dataset['squircleOriginalBgImage']; + delete element.dataset['squircleHadInlineBgImage']; + delete element.dataset['squircleOriginalShadow']; + delete element.dataset['squircleHadInlineShadow']; + }

.gitignore (1)
68-69: LGTM!The ignore patterns for internal documentation files are appropriate and follow standard gitignore conventions.
packages/core/package.json (1)
3-3: LGTM!The version bump to 1.2.0 correctly follows semantic versioning for the new SVG-based border rendering feature. The minor version increment appropriately signals backward-compatible new functionality.
website/cornerkit.js (1)
1-1: Skip detailed review - build artifact.This appears to be a minified/bundled build artifact. Static analysis warnings about variable declarations are false positives common in minified code. Ensure this file is consistently generated from source and not manually edited.
packages/core/src/core/types.ts (4)
8-32: LGTM!The
GradientStopinterface is well-designed with flexibleoffsettyping (string | number) and comprehensive JSDoc. The union type appropriately handles both percentage strings and decimal numbers.
34-107: LGTM with runtime validation dependency.The
BorderConfiginterface is well-designed with appropriate optional fields and strong typing forstyle. The JSDoc clearly documents constraints (width 1-8, gradient requires 2+ stops), but these are not TypeScript-enforceable. Ensure runtime validation enforces these constraints in the border renderer.
109-126: LGTM!The
BorderRenderOptionsinterface is appropriately marked as internal and contains the necessary render-time parameters. Good encapsulation of implementation details.
152-173: LGTM!Excellent backward compatibility approach. The new
borderobject doesn't break existing code, and the@deprecatedtags clearly guide developers toward the v1.2 API without forcing immediate migration.README.md (2)
6-6: LGTM!Bundle size documentation is consistent throughout (5.50 KB) and transparently acknowledges the increase due to new SVG border rendering features while remaining under the 6KB budget.
Also applies to: 15-15, 76-76, 330-330
246-311: LGTM!The border support documentation is comprehensive and well-structured. It covers all border styles, provides clear examples, documents data attributes, and includes explicit migration guidance from v1.1 to v1.2 with backward compatibility notes.
packages/core/tests/integration/fixtures/test-page.html (2)
389-446: LGTM!The test fixture comprehensively covers border rendering scenarios including solid/dashed/dotted styles, gradient borders, dark background testing for anti-aliasing, and data-attribute-driven configuration. The element sizing and backgrounds are appropriate for visual testing.
532-540: LGTM!The border test initialization covers all border styles systematically. The gradient border test uses numeric offsets (0, 1) which correctly tests the flexible
offset: string | numbertyping from GradientStop.packages/core/tests/unit/data-attributes.test.ts (4)
306-360: LGTM!The integration tests comprehensively validate border attribute parsing combinations, including edge cases like width-only (no border created) and color-only (default width=1). The tests correctly verify that
coloris required for border creation.
362-416: LGTM!The
parseBorderWidthtests provide comprehensive coverage including valid numbers, invalid inputs with warning verification, and edge cases (0, max value 8). The parser correctly handles all scenarios.
418-474: LGTM!The
parseBorderColortests cover all major CSS color formats (hex, rgb, rgba, hsl, named) and correctly handle whitespace trimming and empty values. The parser appropriately doesn't validate color format, allowing any CSS color value.
476-536: LGTM!The
parseBorderStyletests comprehensively validate all three border styles with proper edge case handling including case-insensitive parsing, whitespace trimming, and invalid value warnings. The validation against the allowed styles is correctly implemented.packages/core/tests/unit/path-generator.test.ts (1)
244-319: LGTM! Comprehensive test coverage for inset path generation.The test suite thoroughly covers the new
insetparameter functionality including valid SVG syntax, coordinate verification, degenerate cases (large inset), default behavior, and parseability. The test at line 270-274 correctly verifies that the inset path's starting Y coordinate equals the inset amount.packages/core/src/math/figma-squircle.ts (1)
320-340: LGTM! Path generation with inset offset is correctly implemented.The path correctly translates absolute coordinates (M, L commands) by the inset offset while keeping relative commands (c, a) unchanged. The algorithm mirrors the main
generateFigmaSquirclePathfunction structure for consistency.packages/core/tests/unit/clippath.test.ts (5)
748-781: LGTM! Comprehensive SVG border rendering tests.The test suite thoroughly covers the new Feature 006 SVG-based border rendering including SVG creation, attribute verification, isolation context, and the clip-path being empty when border is configured (as expected since borders use SVG approach instead of CSS clip-path).
841-901: LGTM! Background capture and restoration tests are thorough.Tests correctly verify:
- Original background is captured in
data-squircle-original-bgattribute- Element background is made transparent
- SVG includes the background fill path
- Background is only captured once on subsequent updates
903-941: LGTM! Remove and cleanup tests verify proper state restoration.The tests correctly verify that
remove()restores:
- Original background color
- Removes isolation context
- Removes data attributes
- Removes the SVG border element
This ensures no visual artifacts remain after squircle removal.
1099-1126: LGTM! Dotted border test correctly verifies anti-aliasing fix.The test confirms that dotted borders use the inset path approach (no
clip-pathattribute) rather than the clip-path approach used by solid/dashed borders. This is the documented SC-001 fix for anti-aliasing artifacts on dark backgrounds.
1243-1276: LGTM! Rapid resize test correctly verifies stability.The test simulates 10 rapid resizes and verifies no errors are thrown and the final state is correct. The expected viewBox
0 0 280 235correctly matches the loop calculations (100 + 9×20 = 280, 100 + 9×15 = 235).packages/core/src/utils/data-attributes.ts (3)
97-119: LGTM! Border width parsing follows established patterns.The
parseBorderWidthfunction correctly mirrors the existingparseRadiusandparseSmoothingparsers with consistent validation, warning messages, and return behavior.
128-142: LGTM! Border color parsing correctly handles empty values.The function appropriately returns
undefinedfor empty strings after trimming, allowing the browser to handle color validation.
151-177: LGTM! Border style parsing with case-insensitive validation.The function correctly normalizes input to lowercase before validation, allowing flexible attribute values like
data-squircle-border-style="Dashed". The warning message helpfully lists all valid options.packages/core/src/math/path-generator.ts (1)
30-50: LGTM! Clean integration of inset parameter.The changes are minimal and well-integrated:
- Optional
insetparameter with sensible default (0)- Clean conditional routing to the appropriate path generator
- Existing edge case handling (zero dimensions/radius) is appropriately bypassed for inset paths since the inset function handles its own degenerate cases
packages/core/tests/integration/border-visual.test.ts (2)
1-13: LGTM! Well-structured integration test setup.The test file provides comprehensive coverage for the new SVG-based border rendering feature. The
setupTestPagehelper andbeforeEachpattern ensure consistent test isolation.
567-719: Excellent data-attribute test coverage.The T050 tests thoroughly validate the data-attribute API including edge cases like color-only (default width), width-only (no border created), and style variants. The
scrollIntoViewIfNeeded()calls correctly handle lazy-loading behavior.packages/core/README.md (3)
5-12: Documentation accurately reflects the v1.2.0 changes.The bundle size badge and description are updated consistently to reflect the new 5.50 KB gzipped size. The feature addition (SVG border rendering) is clearly highlighted.
295-500: Comprehensive border documentation with excellent examples.The Border Support section is well-structured with clear examples for all border types (solid, dashed, dotted, gradient, custom dashArray). The troubleshooting section at Lines 474-500 proactively addresses common issues like gradient stops requirements.
427-445: Good migration guidance for backward compatibility.The migration section clearly shows both the legacy API (v1.1) and new API (v1.2) side by side, making it easy for existing users to understand the transition path.
packages/core/tests/unit/border.test.ts (5)
1-33: Well-structured test file with comprehensive coverage.The test file is well-organized with clear test categories (T011, T012, T037) and a reusable
baseOptionsfixture. The imports correctly reference the functions under test from the border renderer module.
192-232: Good gradient fallback testing.The tests for single-stop gradient (Line 192) and empty gradient array (Line 214) correctly verify the fallback behavior to solid colors. This aligns with the documented requirement that gradients need at least 2 stops.
343-352: Type assertion for undefined border test.The test uses
undefined as unknown as BorderConfigwhich is a valid approach for testing defensive code paths. This ensures the renderer handles malformed inputs gracefully.
386-432: DOM cleanup in removeBorderSVG tests is properly handled.The
beforeEach/afterEachhooks correctly create and remove the container element, preventing test pollution.
605-641: Idempotent style injection verified.The test at Line 619 correctly verifies that
injectBorderStyles()only inserts one style element regardless of how many times it's called. The cleanup viaresetBorderStylesInjection()inafterEachensures test isolation.packages/core/src/index.ts (3)
142-158: Backward compatibility implementation is well-designed.The legacy
borderWidth/borderColorprops are correctly converted to the newborderobject structure. The fallback values (width: 1, color: '#000000') provide sensible defaults. This ensures existing v1.1 code continues to work.
452-461: Update method correctly handles border property merging.The
update()method properly handles both the newborderobject and legacyborderWidth/borderColorprops with appropriate fallback to existing config values.
828-842: Public API exports are comprehensive.The new type exports (
BorderConfig,GradientStop,BorderRenderOptions) and parser exports (parseBorderWidth,parseBorderColor,parseBorderStyle) properly expose the v1.2 border API for external consumers.website/index.html (3)
300-376: Comprehensive border control UI.The new border controls including style select, gradient toggle, and gradient color pickers provide a complete interface for testing all v1.2 border features. The controls are properly labeled with
aria-labelattributes for accessibility.
507-551: Excellent demo sections for new border features.The Border Styles gallery (Lines 507-533) and Dark Background Demo (Lines 535-551) effectively showcase the v1.2 capabilities including the anti-aliasing fix (SC-001). The dark background demo specifically highlights the elimination of fringe artifacts.
929-940: Good addition of Svelte example.The Svelte code example completes the framework coverage alongside React and Vue, providing consistent documentation for users of all major frameworks.
packages/core/src/renderers/clippath.ts (3)
11-11: LGTM on the new import.The imports from
./borderare correctly structured and provide the necessary utilities for SVG border rendering.
104-171: LGTM on theremove()cleanup logic.The restoration logic correctly distinguishes between inline styles and CSS-driven styles, ensuring proper cascade behavior. The cleanup of data attributes after restoration is well-ordered.
206-226: LGTM on the style capture mechanism.The logic correctly captures original styles only once and tracks whether they were inline or CSS-driven. Using data attributes for persistence across updates is appropriate.
packages/core/src/renderers/border.ts (12)
1-16: LGTM on the module structure and constants.The SVG namespace constant and border width range constants (1-8px) are well-defined. The default transparent color is appropriate for fallback scenarios.
35-49: LGTM on border width validation.The function correctly handles invalid inputs, NaN values, and dimension-based clamping per the specification.
57-62: LGTM on border color validation.The function correctly normalizes input and provides a safe fallback. Delegating CSS color syntax validation to the browser is appropriate.
69-75: LGTM on skip border logic.The logic correctly identifies when border rendering should be skipped. Single-stop gradients are allowed through here and handled gracefully in
createBorderSVGwith a fallback to solid color.
136-136: Random ID generation is suitable for this use case.The
Math.random().toString(36).substring(2, 11)approach generates sufficiently unique IDs for clip-path references within a single page context. For high-volume scenarios or stricter uniqueness requirements, a counter-based approach could be considered, but this is adequate for typical usage.
158-167: LGTM on gradient stop handling.The offset handling correctly supports both numeric (0-1) and string formats. The iteration over stops is straightforward.
175-200: LGTM on background path with anti-aliasing compensation.The conditional stroke widths based on border style effectively cover anti-aliased edges visible through gaps. Clipping to the squircle shape prevents corner bleeding.
207-229: LGTM on border stroke path logic.The differentiated approach for dotted (inset path without clip-path) vs. solid/dashed (2× stroke with clip-path) effectively handles anti-aliasing artifacts. The
vector-effect: non-scaling-strokeensures consistent border appearance at different scales.
243-248: LGTM on border SVG removal.The function correctly finds and removes the border SVG element by class name.
253-276: LGTM on global style injection.The idempotent injection pattern with a module-level flag and SSR safety check is appropriate. The CSS rules correctly position the SVG behind content.
281-287: LGTM on test reset utility.The reset function properly cleans up both the flag and the injected style element, enabling proper test isolation.
82-89: Code approach is adequate — getComputedStyle normalizes transparent colors to rgba format.Modern browsers normalize all transparent color formats (including
hsla,transparentkeyword, etc.) torgba(0, 0, 0, 0)viagetComputedStyle. The function correctly handles both the literal"transparent"string andrgba(0, 0, 0, 0)variants with varying whitespace, covering all practical cases in current browsers.website/app.js (10)
45-45: CDN version updated to 1.2.0.The CDN URL correctly reflects the new version for the HTML code template.
165-177: LGTM on border object string builder.The
getBorderObjecthelper correctly formats the border configuration for various code templates, handling style, gradient, and color appropriately.
199-218: Good documentation of gradient limitation in HTML template.The comment noting that gradient borders require the JS API (lines 202-203) is helpful for users who might try to use data attributes for gradients.
591-599: LGTM on new gallery examples.The new examples comprehensively demonstrate v1.2 border features including style variants (solid, dashed, dotted, gradient) and dark background scenarios for the anti-aliasing fix.
631-658: LGTM on gallery example application with v1.2 API.The function correctly constructs the nested
borderobject, handling both gradient and solid color cases with theme-aware color mapping.
858-884: LGTM on updated border config retrieval.The function correctly reads from the new UI controls (style select, gradient toggle, color pickers) and constructs the appropriate configuration object.
955-1006: LGTM on new event handlers.The handlers for gradient toggle, border style, and gradient color changes follow the established pattern in the codebase, using
requestAnimationFramewith debounced updates for smooth performance.
1475-1478: Good approach for theme change re-rendering.The remove-then-apply pattern with the explanatory comment (lines 1475-1477) correctly addresses the background color recapture issue during theme changes. This ensures the SVG border receives the updated background color.
1142-1159: LGTM on event listener wiring.The new controls are correctly wired with appropriate event types (
changefor select and checkbox,inputfor color pickers).
795-808: LGTM on playground preview border config construction.The function correctly builds the nested
borderobject using the v1.2 API, choosing between gradient and solid color based on theuseGradientflag.

In packages/core/README.md around line 561, the documented SC-006 unit coverage
value (84.9%) is below the stated target (>90%); either update the README to
reflect the current actual target/value or add tests to raise coverage above
90%. If choosing documentation, change the SC-006 line to the correct
target/value and add a short note explaining the current status; if choosing
tests, run the coverage report to find uncovered modules, add focused unit tests
for those areas, run coverage until the total exceeds 90%, and update CI if
needed to enforce the SC-006 threshold.

🌐 Web query:
CSS inset property browser support Safari 13
💡 Result:
Short answer: No — Safari 13 does not support the CSS inset shorthand. Support begins in Safari 14.1+. (developer.mozilla.org)
Workaround: use top/right/bottom/left instead (or feature-detect via @supports if needed).

Replace inset: 0 with longhand properties for Safari 13 compatibility.
The inset shorthand property (line 1408) is not supported in Safari 13, which is your minimum supported browser version. Use the longhand equivalents instead:
.cornerkit-border {
position: absolute;
- inset: 0;
+ top: 0;
+ right: 0;
+ bottom: 0;
+ left: 0;
z-index: -1;
pointer-events: none;

In website/styles.css around lines 1387 to 1410, the .cornerkit-border rule uses
the inset shorthand (inset: 0) which breaks in Safari 13; replace that shorthand
with longhand properties top: 0; right: 0; bottom: 0; left: 0; (keeping
position: absolute, z-index: -1, and pointer-events: none unchanged) so the
element remains fully inset in browsers that don’t support inset.
