10-13: Remove duplicate JSDoc comment.This JSDoc comment duplicates the one at the top of the file (lines 1-4).
-/** - * Modern CSS-based color manipulation utilities - * Uses color-mix() and relative color syntax when supported - */
33-33: Consider error handling for unsupported browsers.Based on the retrieved learning, modern CSS features are fully supported in target browsers. However, the current fallback silently returns the original color when features aren't supported, which could mask issues during development.
Given that @clerk/clerk-js only supports browsers from the last two years where modern CSS features are available, should we throw an error instead of silently falling back? This would help catch configuration issues early.

color.toString()check is redundant sincecoloris already checked for truthiness on line 73.- if (!color.toString()) return color;packages/clerk-js/src/ui/utils/colors/colorOptionToHslaScale.ts (1)
172-185: Optimize modern CSS path by avoiding unnecessary parsing.The modern CSS path should avoid HSLA conversion entirely for better performance.
- // Fall back to HSLA approach - only parse if modern CSS is not supported - const userScale = processColorInput(colorOption, false); - const finalScale = generateLegacyAlphaScale(userScale['500']); - return prefixAndStringifyScale(finalScale, prefix); + // Fall back to HSLA approach + const hslaColor = colors.toHslaColor(colorOption); + if (hslaColor && typeof hslaColor === 'object') { + const finalScale = generateLegacyAlphaScale(hslaColor); + return prefixAndStringifyScale(finalScale, prefix); + } + return undefined;

packages/clerk-js/src/ui/utils/colors/modern.ts (2)
14-119: Well-structured modern color utilities with proper feature detection.The implementation correctly prioritizes relative color syntax over color-mix() where appropriate, uses proper bounds checking with constants, and provides consistent fallback behavior. The caching mechanism integration is also well done.
124-126: Clean wrapper function for cached color support detection.Simple and effective wrapper that leverages the caching mechanism.
packages/clerk-js/src/ui/utils/colors/colorOptionToHslaScale.ts (6)
7-11: Excellent use of TypeScript mapped types.The type definitions effectively use mapped types and template literal types to create type-safe prefixed color scales.
34-47: Comprehensive validation with clear error messages.The validation functions provide helpful error messages that clearly indicate missing shades and requirements.
87-109: Well-implemented lightness scale generation.The algorithm correctly calculates lightness steps using the configuration constants and applies them systematically to generate light and dark shades from the base color.
162-191: Smart modern/legacy fallback strategy for alpha scales.The function intelligently chooses between modern CSS and legacy HSLA approaches based on browser support, optimizing performance while maintaining compatibility.
193-235: Robust lightness scale generation with proper user override support.The implementation correctly handles both single color inputs and partial scales, merging user-defined shades with generated ones while maintaining the base color requirement.
1-6: Verify file duplication concern.A previous comment questioned if this file differs from
packages/clerk-js/src/ui/utils/colorOptionToHslaScale.ts. The file paths suggest potential duplication.#!/bin/bash # Check if there's another colorOptionToHslaScale file outside the colors directory fd -t f "colorOptionToHslaScale" --exclude "packages/clerk-js/src/ui/utils/colors/"

9-63: Optimize performance by avoiding repeated feature detection calls.The current implementation calls
hasModernColorSupport()on every function invocation, which is inefficient since CSS feature support doesn't change during runtime.Consider implementing the suggestion from the past review to define the colors object once:
-export const colors = { - toHslaColor: (color: string | undefined): string | HslaColor | undefined => { - if (!color) return undefined; - if (hasModernColorSupport()) { - return color; - } - return legacyColors.toHslaColor(color); - }, - // ... other functions with repeated hasModernColorSupport() calls -}; +export const colors = hasModernColorSupport() ? { + toHslaColor: (color: string | undefined): string | HslaColor | undefined => { + if (!color) return undefined; + return color; + }, + toHslaString: (color: HslaColor | string | undefined): string | undefined => { + if (!color) return undefined; + if (typeof color === 'string') { + return color; + } + return legacyColors.toHslaString(color); + }, + changeHslaLightness: legacyColors.changeHslaLightness, + setHslaAlpha: legacyColors.setHslaAlpha, + lighten: modernColors.lighten, + makeTransparent: modernColors.makeTransparent, + makeSolid: modernColors.makeSolid, + setAlpha: modernColors.setAlpha, + adjustForLightness: modernColors.adjustForLightness, +} : { + toHslaColor: legacyColors.toHslaColor, + toHslaString: legacyColors.toHslaString, + changeHslaLightness: legacyColors.changeHslaLightness, + setHslaAlpha: legacyColors.setHslaAlpha, + lighten: legacyColors.lighten, + makeTransparent: legacyColors.makeTransparent, + makeSolid: legacyColors.makeSolid, + setAlpha: legacyColors.setAlpha, + adjustForLightness: legacyColors.adjustForLightness, +};

packages/clerk-js/src/ui/utils/colors/__tests__/colorOptionToHslaScale.spec.ts (4)
1-63: Excellent test setup with comprehensive mocking.The test suite demonstrates thorough preparation with realistic mock implementations and proper isolation of dependencies. The beforeEach setup ensures clean state between tests, and the mock implementations accurately simulate the expected behavior of the color utilities.
65-141: Comprehensive alpha scale test coverage.The tests cover all essential scenarios for alpha scale generation including undefined inputs, modern CSS support detection, legacy fallbacks, complete color scale objects, and prefix application. The test cases properly validate both the function calls and expected outcomes.
143-236: Thorough lightness scale testing with good error validation.The lightness scale tests properly cover partial color scales, base color validation, and the critical requirement for the 500 shade. The error handling tests ensure proper validation of required shades and graceful handling of invalid inputs.
238-276: Good error handling and edge case coverage.The tests properly validate error conditions including empty strings, incomplete scales, invalid color objects, and various prefix applications. This ensures robust behavior across different input scenarios.
packages/clerk-js/src/ui/utils/colors/colorOptionToHslaScale.ts (7)
1-12: Good TypeScript usage and clear type definitions.The internal types
InternalColorScaleandWithPrefixare well-defined and provide good type safety for the scale conversion logic. The imports are well-organized and properly typed.
14-42: Solid validation and conversion utilities.The validation functions provide clear error messages and proper checking for required shades. The
convertToHslaScalefunction safely handles color conversion with proper null checking.
44-58: Type-safe prefix application with proper string handling.The
prefixAndStringifyScalefunction properly handles the type transformations and ensures only valid colors are included in the final result. The type assertion at line 53 is safe given the null check.
60-101: Well-implemented scale generation for both modern and legacy approaches.The functions clearly separate modern CSS generation from legacy HSLA calculations. The legacy lightness scale uses proper mathematical calculations based on constants, and the alpha scale correctly applies predefined alpha values.
103-140: Good user preference handling and input processing.The merge function properly prioritizes user-defined colors over generated ones, and the
processColorInputfunction handles both string and object inputs with appropriate validation based on requirements.
142-171: Robust alpha scale generation with proper feature detection.The function correctly checks for modern CSS support and falls back to legacy implementation when needed. The type assertions are safe given the controlled flow and validation performed.
173-215: Comprehensive lightness scale implementation with good error handling.The function properly handles both string and object inputs, validates base color requirements, and merges user-defined colors with generated scales. The error handling for missing base colors is appropriate and clear.
packages/clerk-js/src/ui/utils/colors/__tests__/constants.spec.ts (5)
1-32: Thorough COLOR_SCALE validation with proper structure testing.The tests verify not only the correct values and order but also the immutability characteristics and length validation. This ensures the fundamental color scale is correctly defined.
34-68: Comprehensive shade grouping and lightness configuration tests.The tests properly validate the relationship between light shades, dark shades, and the complete ALL_SHADES array. The lightness configuration validation ensures the mathematical constants are correct for scale generation.
70-108: Excellent alpha values validation with boundary checking.The tests ensure alpha values are within valid ranges (0-1), properly ordered, and correspond to the correct number of shades. The percentage validation covers all shades and validates boundaries.
110-186: Comprehensive lightness mix data and relative steps validation.The tests thoroughly validate the structure of lightness mixing data, ensuring proper mix colors (white/black/null) and the special case for the 500 shade. The relative shade steps validation ensures proper step progression for both light and dark shades.
188-237: Complete bounds and limits validation with reasonable value checking.The tests validate all color bounds (RGB, alpha, hue, percentage) and modern CSS limits, ensuring the values are within reasonable ranges and have the expected structure. This provides confidence in the constraint values used throughout the color system.
packages/clerk-js/src/ui/utils/memoize.ts (1)
34-36: Add explicit return type annotation.The function already has explicit
voidreturn type, which follows the coding guidelines.packages/clerk-js/src/ui/utils/__tests__/memoize.spec.ts (6)
1-12: Excellent test setup with proper cleanup.The test setup properly clears the cache before and after each test, preventing test interference. This is essential for testing stateful utilities like memoization.
14-60: Comprehensive basic memoization tests.The tests thoroughly cover:
- Basic memoization behavior
- Different argument scenarios
- Multiple argument handling
This provides good coverage of the core functionality.
62-91: Good coverage of custom key function feature.The tests validate both custom key function usage and default JSON.stringify behavior. The object equality test (lines 79-90) is particularly valuable for testing the default serialization behavior.
93-126: Excellent cache management testing.Tests properly verify cache size tracking and clearing functionality. The verification that functions are called again after cache clearing (lines 122-124) is crucial for ensuring cache integrity.
128-149: Good TypeScript type preservation testing.Tests verify that the memoized function maintains the original function's type signature, which is important for type safety in TypeScript.
151-194: Comprehensive edge case coverage.The tests cover important edge cases including:
- Undefined/null arguments
- Complex objects
- Error handling
However, the error handling test (lines 175-193) reveals a potential issue: errors are not being cached, which means failing functions will be called repeatedly. This might be intentional but should be documented.
Let me verify the error handling behavior in the memoize implementation:
#!/bin/bash # Description: Check if the memoize function has any error handling logic # Expected: Should find error handling code or confirm errors aren't cached rg -A 5 -B 5 "catch|throw|error" packages/clerk-js/src/ui/utils/memoize.tspackages/clerk-js/src/ui/utils/colors/index.ts (2)
1-8: LGTM! Clean imports and setup.The imports are well-organized and the feature detection setup is appropriate.

175-217: LGTM! Comprehensive adjustForLightness testing.Good coverage of default values, custom values, and percentage limiting.
219-231: LGTM! Important fallback behavior testing.This section ensures graceful degradation when modern CSS features are unavailable, which is crucial for robustness.
packages/clerk-js/src/ui/utils/colors/__tests__/index.spec.ts (5)
3-41: LGTM! Excellent mocking strategy for testing delegation logic.The comprehensive mocking of all dependencies (
cssSupports,legacy, andmodernmodules) allows for precise testing of the delegation behavior without implementation details bleeding through.
48-62: LGTM! Proper testing of re-exported functionality.Good verification that the expected functions and modules are properly re-exported.
64-113: LGTM! Thorough testing of core conversion functions.The tests properly verify:
- Undefined input handling

- Various hex formats (3, 4, 6, 8 digit)
- RGB/RGBA with numeric and percentage values
- Different color combinations (red, blue, green, yellow)
The precision handling for alpha values (line 15, 25) shows good attention to floating-point accuracy.
60-85: LGTM! Thorough HSL/HSLA parsing with edge case handling.Good coverage of:
- Basic HSL/HSLA formats
- Degree unit handling
- Hue value normalization (>360 and negative values)
The hue normalization tests (lines 76-84) are particularly important for robust color handling.
87-103: LGTM! Proper HWB color format support.Good coverage of HWB color space including alpha channel and boundary conditions.
105-121: LGTM! Comprehensive CSS keyword color support.Excellent coverage of named colors including the important
transparentkeyword and gray/grey equivalents.

142-154: Consider renaming to reflect multiple implementation strategies.The function name
getColorMixis misleading since it doesn't always return color-mix syntax - it can return relative color syntax or the original color based on CSS support.Consider renaming to better reflect its purpose:
-export function getColorMix(color: string, shade: ColorShade): string { +export function getOptimalColorVariant(color: string, shade: ColorShade): string {This name better reflects that it chooses the optimal color implementation strategy based on browser capabilities.

packages/clerk-js/src/ui/utils/colors/utils.ts (5)
1-6: LGTM - Clean imports and type safety.The imports are well-structured with proper type-only imports and clear dependency organization.
8-26: Excellent optimization with frozen empty scale.The pre-computed frozen object pattern combined with spread operator cloning is an efficient approach for avoiding repeated object creation while ensuring immutability.
28-57: Well-implemented memoization with clear cache keys.The memoized generators use descriptive cache key functions and follow consistent patterns. This will provide significant performance benefits for repeated color generations.
89-114: Robust relative color syntax generation with proper fallbacks.The function correctly handles the base case (shade 500) and properly calculates lightness adjustments using the predefined configuration. The mathematical expressions for light and dark shade calculations are accurate.
122-134: Clean implementation with consistent patterns.Both functions follow the same pattern of checking for the base shade and using the configuration data appropriately.
packages/clerk-js/src/ui/utils/colors/scales.ts (10)
1-6: Clean imports with proper type organization.The imports are well-structured, separating types from implementation details and clearly showing dependencies.
8-12: Well-designed type definitions for internal use.The
InternalColorScaleandWithPrefixtypes provide clear abstractions for the themed scale functionality.
20-33: Type-safe implementation addresses previous concerns.The function correctly implements type-safe prefix application without using
anytype assertions, addressing the previous review comment about type safety.
35-63: Solid modern and legacy alpha scale implementations.Both functions follow consistent patterns and properly handle the alpha value calculations. The modern version leverages the memoized generators while the legacy version directly manipulates HSLA values.
65-107: Comprehensive lightness scale generation with proper mathematical calculations.The legacy implementation correctly calculates lightness steps and applies them in the right direction (lighter for shades < 500, darker for shades > 500). The modern version properly delegates to the memoized utilities.
112-139: Robust input processing and merging logic.The
processColorInputfunction handles all input types correctly with proper type guards, andmergeWithUserScaleprovides a clean way to combine generated and user-provided scales.
146-187: Excellent unified API with automatic capability detection.Both
generateAlphaScaleandgenerateLightnessScaleprovide clean abstractions that automatically choose the best implementation based on CSS support, with proper fallbacks for invalid inputs.
189-203: Good separation of concerns with direct access to implementations.Providing direct access to modern and legacy implementations is valuable for testing and scenarios where CSS support is guaranteed.
209-232: Clean CSS conversion and prefixing utilities.The functions properly handle the conversion between internal representations and CSS-ready values while maintaining type safety.
241-276: Well-designed themed scale conversion functions.Both
colorOptionToThemedAlphaScaleandcolorOptionToThemedLightnessScaleprovide clean APIs for converting color inputs to themed, prefixed scales. The functions handle undefined inputs gracefully and maintain proper type safety.

🧹 Nitpick comments (3)
packages/clerk-js/src/ui/utils/colors/utils.ts (3)
52-60: Consider parameter validation for better robustness.The function handles optional alpha parameter well, but consider adding basic validation for the color parameter format.
function createRelativeColorString( color: string, hue: string, saturation: string, lightness: string, alpha?: string, ): string { + if (!color) { + throw new Error('Color parameter is required'); + } return `hsl(from ${color} ${hue} ${saturation} ${lightness}${alpha ? ` / ${alpha}` : ''})`; }
108-117: Fix misleading JSDoc comment.The JSDoc comment for
createAlphaColorMixincorrectly describes it as creating a general "color-mix string" when it specifically creates an alpha color-mix string./** - * Create a color-mix string + * Create an alpha color-mix string * @param color - The base color - * @param mixColor - The color to mix with - * @param percentage - The percentage of the mix + * @param alphaPercentage - The alpha percentage * @returns The color-mix string */ export function createAlphaColorMix(color: string, alphaPercentage: number): string { return colorGenerators.alphaColorMix(color, alphaPercentage); }
158-165: Verify mix data structure and error handling.The function assumes
mixData.mixColorexists but could benefit from more defensive programming.export function generateColorMixSyntax(color: string, shade: ColorShade): string { if (shade === 500) return color; const mixData = LIGHTNESS_MIX_DATA[shade]; - if (!mixData.mixColor) return color; + if (!mixData || !mixData.mixColor) return color; return createColorMix(color, mixData.mixColor, mixData.percentage); }

1-7: LGTM! Clean imports following TypeScript best practices.The imports are well-organized with proper type-only imports and clear dependency structure.
8-26: Excellent performance optimization with pre-computed frozen object.The approach of creating a pre-computed frozen empty color scale and providing a factory function is a smart optimization that avoids repeated object creation while maintaining immutability.
39-41: Add explicit return type for better type safety.Following the TypeScript coding guidelines for explicit return types on public APIs.
-function createColorMixString(baseColor: string, mixColor: string, percentage: number): string { +function createColorMixString(baseColor: string, mixColor: string, percentage: number): string {Wait, the return type is already explicit. This function looks good as-is.
75-93: Excellent use of memoization for performance optimization.The memoized generators with well-designed cache keys will significantly improve performance for repeated color calculations. The cache key strategy effectively captures all parameters.
125-150: Well-implemented relative color syntax generation with proper fallbacks.The function correctly handles the base case (shade 500) and implements proper lightness calculations for both light and dark shades using the configuration constants.
178-190: Excellent progressive enhancement with CSS feature detection.The function properly implements a cascade of modern CSS features with appropriate fallbacks, leveraging the known browser support for modern CSS features in the target environment.
Based on the retrieved learning, since @clerk/clerk-js only supports browsers from the last two years, modern CSS features like
color-mix()and relative color syntax are fully supported, making this progressive enhancement approach ideal for graceful degradation in edge cases.

47-47: Consider removing unnecessary type assertion.The type assertion
as ColorScale<string>may be unnecessary sincecreateEmptyColorScale()returns the correct type and all assignments maintain string values.The type assertion might be redundant:
- return scale as ColorScale<string>; + return scale;Verify this change doesn't break type checking before applying.
64-64: Apply consistent type assertion pattern.Similar to the previous comment, this type assertion pattern should be consistent across all scale generation functions.
Consider removing if the types align correctly:
- return scale as ColorScale<string>; + return scale;
232-233: Simplify complex type assertion.The chained type assertions make the code harder to understand and could hide type safety issues.
Consider breaking this into steps for clarity:
function prefixAndConvertScale<Prefix extends string>( scale: ColorScale<string>, prefix: Prefix, ): WithPrefix<InternalColorScale<HslaColorString>, Prefix> { const cssScale = convertScaleToCssStrings(scale); - return applyScalePrefix(cssScale, prefix) as unknown as WithPrefix<InternalColorScale<HslaColorString>, Prefix>; + const prefixedScale = applyScalePrefix(cssScale, prefix); + return prefixedScale as WithPrefix<InternalColorScale<HslaColorString>, Prefix>; }

10-18: Excellent performance optimization with frozen object.The use of
Object.freezeon the pre-computed empty color scale is a smart optimization that prevents unnecessary object creation and mutations.
77-97: Verify complex lightness calculation logic.The relative color syntax generation uses complex lightness calculations with target values and steps. Please ensure these mathematical formulas produce the expected color progression.
The lightness calculations look complex. Let's verify the mathematical formulas work as expected:
#!/bin/bash # Description: Search for any tests that validate the lightness calculation formulas # Expected: Find test files that verify the color progression behavior rg -A 10 -B 5 "generateRelativeColorSyntax|TARGET_LIGHT|TARGET_DARK|LIGHT_STEPS|DARK_STEPS" --type tspackages/clerk-js/src/ui/utils/colors/scales.ts (2)
148-189: Well-designed unified API with feature detection.The automatic selection between modern and legacy implementations based on CSS support is elegant and provides seamless fallback behavior.
91-92: Verify legacy lightness calculation accuracy.The lightness step calculations use division by array length, which should account for the correct number of steps in the progression.
Verify the lightness step calculations produce expected results:
#!/bin/bash # Description: Look for tests validating legacy lightness calculations # Expected: Find test cases that verify the lightness step formulas rg -A 15 -B 5 "lightStep|darkStep|LIGHTNESS_CONFIG" --type ts

Learning: In the Clerk JavaScript repository, changeset headers support single quotes syntax (e.g., '@clerk/backend': minor) and work fine with their current changesets integration, so there's no need to change them to double quotes.

Learning: In the Clerk JavaScript repository, contributors create intentionally empty changeset files (containing only the YAML delimiters) when a PR touches only non-published parts of the codebase (e.g., sandbox assets). This signals that no package release is required, so such changesets should not be flagged as missing content.

Learning: In packages/clerk-js/src/ui/elements/LineItems.tsx, the Title component's React.forwardRef should use HTMLTableCellElement as the generic type parameter, even though it renders a Dt element. This is the correct implementation according to the codebase maintainer.

Learning: In TypeScript, always define explicit return types for functions, especially for public APIs, to ensure type safety and clarity.

1-13: LGTM - Clear module documentation and structureThe module documentation clearly explains the purpose and the duplicate comment provides good emphasis on the modern CSS approach.
18-34: LGTM - Well-implemented lighten method with proper fallback logicThe method correctly implements the feature detection pattern, handles edge cases, and uses appropriate mathematical conversions. The percentage * 100 conversion and clamping with constants are well-implemented.
53-67: LGTM - Solid implementation with proper fallback strategyThe method correctly implements both relative color syntax and color-mix fallbacks. The approach of mixing a color with itself at 100% is clever for removing transparency when relative color syntax isn't available.
92-119: LGTM - Sophisticated lightness adjustment with proper constraintsThe method implements advanced lightness adjustment logic with appropriate safeguards:
- Uses
max()function to prevent colors from becoming too dark- Applies multipliers for more noticeable effects
- Implements proper fallback to color-mix with white
- Clamps adjustments to reasonable limits
The complex relative color syntax expression is well-documented and mathematically sound.
