🧹 Nitpick comments (14)
src/lib/forms/radio/Radio.svelte (1)
34-37: Consider extracting the theme to avoid duplicategetThemecalls.Both
labelClsandinputClscallgetTheme("radio")separately within their$derivedstatements. Extracting the theme once would reduce redundant calls on reactive updates.Apply this diff to extract the theme:
const { input, label } = $derived(radio({ color, tinted: !!getContext("background"), custom, inline })); - const labelCls = $derived(label({ class: clsx(getTheme("radio")?.label, styling.label) })); - const inputCls = $derived(input({ class: clsx(getTheme("radio")?.input, className ?? inputClass) })); + const theme = $derived(getTheme("radio")); + const labelCls = $derived(label({ class: clsx(theme?.label, styling.label) })); + const inputCls = $derived(input({ class: clsx(theme?.input, className ?? inputClass) }));src/lib/forms/floating-label/FloatingLabelInput.svelte (1)
48-52: Optimize repeatedgetThemecalls.Each derived class helper independently calls
getTheme("floatingLabelInput"), resulting in five redundant function calls. Extract the theme retrieval into a single derived statement and reuse it.Apply this diff to optimize the theme retrieval:
const { base, input, label, close, combo } = $derived(floatingLabelInput({ variant, size, color })); const isCombobox = $derived(Array.isArray(data) && data.length > 0); -const baseCls = $derived(base({ class: clsx(isCombobox ? "relative" : "", getTheme("floatingLabelInput")?.base, className) })); -const inputCls = $derived(input({ class: clsx(getTheme("floatingLabelInput")?.input, styling.input) })); -const closeCls = $derived(close({ class: clsx(getTheme("floatingLabelInput")?.close, styling.close) })); -const labelCls = $derived(label({ class: clsx(getTheme("floatingLabelInput")?.label, styling.label) })); -const comboCls = $derived(combo({ class: clsx(getTheme("floatingLabelInput")?.combo, styling.combo) })); +const globalTheme = $derived(getTheme("floatingLabelInput")); +const baseCls = $derived(base({ class: clsx(isCombobox ? "relative" : "", globalTheme?.base, className) })); +const inputCls = $derived(input({ class: clsx(globalTheme?.input, styling.input) })); +const closeCls = $derived(close({ class: clsx(globalTheme?.close, styling.close) })); +const labelCls = $derived(label({ class: clsx(globalTheme?.label, styling.label) })); +const comboCls = $derived(combo({ class: clsx(globalTheme?.combo, styling.combo) }));src/lib/buttons/GradientButton.svelte (1)
15-16: Consider extracting the duplicategetTheme()call.The same
getTheme("gradientButton")call is made on consecutive lines. While the performance impact is likely minimal, consolidating to a single call would follow the DRY principle.Apply this diff to extract the theme object:
+ const gradientButtonTheme = $derived(getTheme("gradientButton")); - let baseClass = $derived(base({ class: clsx(getTheme("gradientButton")?.base, className) })); - let outlineWrapperClass = $derived(outlineWrapper({ class: clsx(getTheme("gradientButton")?.outlineWrapper, btnClass) })); + let baseClass = $derived(base({ class: clsx(gradientButtonTheme?.base, className) })); + let outlineWrapperClass = $derived(outlineWrapper({ class: clsx(gradientButtonTheme?.outlineWrapper, btnClass) }));src/lib/forms/fileupload/Fileupload.svelte (1)
35-37: Changes align with PR objectives.The derived class constants correctly implement the new pattern of inlining
getTheme()calls. The logic is sound and defensive with optional chaining.Optional: Consider extracting the repeated
getTheme("fileupload")call.To follow DRY principles, you could extract the theme lookup:
const { base, wrapper, close } = fileupload(); + + const theme = $derived(getTheme("fileupload")); - const wrapperCls = $derived(wrapper({ class: clsx(getTheme("fileupload")?.wrapper, styling.wrapper) })); + const wrapperCls = $derived(wrapper({ class: clsx(theme?.wrapper, styling.wrapper) })); - const baseCls = $derived(base({ size, class: clsx(getTheme("fileupload")?.base, className) })); + const baseCls = $derived(base({ size, class: clsx(theme?.base, className) })); - const closeCls = $derived(close({ class: clsx(getTheme("fileupload")?.close, styling.close) })); + const closeCls = $derived(close({ class: clsx(theme?.close, styling.close) }));However, if this inlined pattern is intentional for fine-grained reactivity or architectural consistency across the codebase, feel free to keep it as-is.
src/lib/forms/textarea/Textarea.svelte (1)
59-67: Consider caching the getTheme result for performance.The logic is correct and aligns with the PR's objective to move getTheme to $derived. However,
getTheme("textarea")is called 9 times within separate $derived blocks. While this works correctly, it could be optimized by caching the theme object:+ const theme = $derived(getTheme("textarea")); - const divCls = $derived(div({ class: clsx(getTheme("textarea")?.div, styling.div) })); + const divCls = $derived(div({ class: clsx(theme?.div, styling.div) })); - const wrapperCls = $derived(wrapper({ class: clsx(getTheme("textarea")?.wrapper, classes?.wrapper) })); + const wrapperCls = $derived(wrapper({ class: clsx(theme?.wrapper, classes?.wrapper) })); // ... and so on for remaining derived constantsThis reduces redundant context lookups while maintaining the same reactivity. That said, if this pattern is intentional across the 70+ components mentioned in the summary, the current approach prioritizes code locality.
src/lib/datepicker/Datepicker.svelte (1)
424-540: Consider consolidating multiple getTheme calls for better performance.The component calls
getTheme("datepicker")12+ times throughout the template. While this works correctly, each call invokesgetThemeContext()and performs the reactive wrapper check.For better performance, consider consolidating to a single derived theme variable:
+ const datepickerTheme = $derived(getTheme("datepicker")); + let { base, input, button, titleVariant, actionButtons, columnHeader, polite, grid, nav, dayButton, monthButton } = datepicker();Then use
datepickerTheme?.input,datepickerTheme?.button, etc. in the template. This reduces the overhead of multiple context lookups while maintaining reactivity.However, if
getThemeis sufficiently optimized (e.g., memoized at the context level), the current approach is acceptable for code clarity.src/lib/progress/Progressbar.svelte (1)
44-49: Consider consolidating getTheme calls for marginal performance improvement.Each of the six derived class constants calls
getTheme("progressbar")separately. While this works correctly, consolidating to a single theme retrieval could reduce overhead:+ const progressbarTheme = $derived(getTheme("progressbar")); const outsideCls = $derived(outside({ class: clsx(progressbarTheme?.outside, classes?.outside) })); const spanCls = $derived(span({ class: clsx(progressbarTheme?.span, classes?.span) })); // ... etcThat said, the current approach is clear and maintainable, so this optimization is optional unless performance profiling indicates getTheme is a bottleneck.
src/lib/accordion/AccordionItem.svelte (1)
69-71: Optional: Consolidate getTheme calls.Similar to other components in this PR, the three derived class constants each call
getTheme("accordionItem")separately. Consider consolidating:+ const accordionItemTheme = $derived(getTheme("accordionItem")); - let baseClass = $derived(base({ class: clsx(getTheme("accordionItem")?.base, className) })); - let buttonCls = $derived(button({ class: clsx(buttonClass, getTheme("accordionItem")?.button, styling.button) })); - let contentCls = $derived(content({ class: clsx(getTheme("accordionItem")?.content, styling.content) })); + let baseClass = $derived(base({ class: clsx(accordionItemTheme?.base, className) })); + let buttonCls = $derived(button({ class: clsx(buttonClass, accordionItemTheme?.button, styling.button) })); + let contentCls = $derived(content({ class: clsx(accordionItemTheme?.content, styling.content) }));The current implementation is functionally correct and follows the PR's pattern, so this is purely an optional optimization.
src/lib/drawer/DrawerHandle.svelte (1)
14-15: Optional: Consolidate getTheme calls.The two derived class constants each call
getTheme("drawerhandle"). For consistency and marginal performance improvement:+ const drawerhandleTheme = $derived(getTheme("drawerhandle")); - let baseClass = $derived(base({ class: clsx(getTheme("drawerhandle")?.base, className) })); - let handleClass = $derived(handle({ class: clsx(getTheme("drawerhandle")?.handle, classes?.handle) })); + let baseClass = $derived(base({ class: clsx(drawerhandleTheme?.base, className) })); + let handleClass = $derived(handle({ class: clsx(drawerhandleTheme?.handle, classes?.handle) }));src/lib/forms/select/Select.svelte (1)
43-45: Consider caching the theme lookup for efficiency.Each derived variable calls
getTheme("select")separately. While functional, you could optimize by callinggetTheme()once and reusing the result:-const baseCls = $derived(base({ class: clsx(getTheme("select")?.base, className) })); -const selectClsFull = $derived(select({ class: clsx(getTheme("select")?.select, styling.select) })); -const closeCls = $derived(close({ class: clsx(getTheme("select")?.close, styling.close) })); +const theme = $derived(getTheme("select")); +const baseCls = $derived(base({ class: clsx(theme?.base, className) })); +const selectClsFull = $derived(select({ class: clsx(theme?.select, styling.select) })); +const closeCls = $derived(close({ class: clsx(theme?.close, styling.close) }));This pattern applies to other components in this PR as well (Search, MegaMenu, Input, etc.).
src/lib/dropdown/DropdownItem.svelte (1)
24-24: Optimize duplicategetThemecalls.The
finalClassderived invokesgetTheme("dropdownItem")twice (once for?.activeand once for?.base), even though only one branch executes. Consider caching the theme result to avoid redundant lookups.Apply this diff:
const { base, active, li } = dropdownItem(); - let finalClass = $derived(isActive ? active({ class: clsx(getTheme("dropdownItem")?.active, styling.active) }) : base({ class: clsx(getTheme("dropdownItem")?.base, className) })); + const theme = $derived(getTheme("dropdownItem")); + let finalClass = $derived(isActive ? active({ class: clsx(theme?.active, styling.active) }) : base({ class: clsx(theme?.base, className) }));src/lib/breadcrumb/Breadcrumb.svelte (1)
19-20: Consider caching the theme lookup to avoid redundant calls.The
getTheme("breadcrumb")call is made twice (lines 19-20). IfgetThemeperforms any computation or lookup, this could impact performance unnecessarily.Consider adding a derived theme reference:
const { base, list } = $derived(breadcrumb({ solid })); + const themeBreadcrumb = $derived(getTheme("breadcrumb")); - let classNav = $derived(base({ class: clsx(getTheme("breadcrumb")?.base, className) })); - let classList = $derived(list({ class: clsx(getTheme("breadcrumb")?.list, styling.list) })); + let classNav = $derived(base({ class: clsx(themeBreadcrumb?.base, className) })); + let classList = $derived(list({ class: clsx(themeBreadcrumb?.list, styling.list) }));src/lib/bottom-navigation/BottomNavItem.svelte (1)
39-44: Consider derivingspanClassto avoid redundant theme lookups.The
getSpanClass()function is called twice during render (lines 66, 71), resulting in multiplegetTheme("bottomNavItem")calls per render cycle. WhilegetCommonClass()is memoized via$derived(line 49),getSpanClass()is not.Consider deriving the span class:
function getCommonClass() { return base({ class: clsx(isActive && (activeClass ?? context?.activeClass), getTheme("bottomNavItem")?.base, className ?? btnClass) }); } - function getSpanClass() { - return span({ class: clsx(isActive && (activeClass ?? context?.activeClass), getTheme("bottomNavItem")?.span, styling.span) }); - } + const spanClassDerived = $derived( + span({ class: clsx(isActive && (activeClass ?? context?.activeClass), getTheme("bottomNavItem")?.span, styling.span) }) + );Then update the template to use
spanClassDerivedinstead ofgetSpanClass().src/lib/banner/Banner.svelte (1)
49-56: Consider extracting derived classes for consistency.Unlike
BottomNav.sveltewhich pre-computes classes using$derived, this component callsgetTheme("banner")inline in the template three times per render. While functional, extracting to$derivedvariables would be more consistent with the pattern used in other components and marginally more efficient.Example:
+ let baseClass = $derived(base({ class: clsx(getTheme("banner")?.base, className) })); + let insideDivClass = $derived(insideDiv({ class: clsx(getTheme("banner")?.insideDiv, styling.insideDiv) })); + let dismissableClass = $derived(dismissableClass({ class: clsx(getTheme("banner")?.dismissable, styling.dismissable) }));Then reference these in the template.

Learning: In Svelte 5, `$state` provides deep reactivity, meaning array mutations like `push()`, `splice()`, `pop()`, etc. trigger reactivity automatically. Unlike previous Svelte versions, immutable updates (spread operator, filter) are not required for `$state` arrays to trigger reactive updates.

Learning: In the Flowbite Svelte library's form components like MultiInput, when handling focus states for validation, avoid hardcoding focus-within classes like 'focus-within:border-primary-500'. Instead, create a dynamic mapping object (e.g., focusWithinClasses) that changes the focus ring color based on the current color state, especially when inputInvalid=true.

Learning: In the Flowbite Svelte library's composite form components like MultiInput, when implementing focus styles, ensure both the container (with focus-within) and the inner input element (with direct focus) have dynamic styling based on the validation state. The input element needs its own focus styles that change to red when inputInvalid=true.

Learning: In the Flowbite Svelte library's form components, both the regular focus styling (controlled by ringClasses) and focus-within styling need to be dynamically adjusted based on validation state. For proper validation styling, create separate objects for focus-within classes (like focusWithinClasses) that use the same color as ringClasses when inputInvalid=true.

Learning: In the Flowbite Svelte library's composite form components like MultiInput, when implementing focus styles with focus-within, create a dedicated focusWithinClasses object with appropriate colors for each state (base, primary, green, red). Using just 'focus-within:ring-1' without color specification won't correctly apply color-specific styling when the input receives focus directly.

Learning: In the Flowbite Svelte library's MultiInput component, the 'inputInvalid' property should be exported and passed to the Wrapper component to properly style the component's ring with red color when validation fails, similar to how the Input component handles validation states.

src/lib/forms/radio/Radio.svelte (1)
40-41: LGTM!The derived classes are correctly applied to the Label component and input element.
src/lib/forms/floating-label/FloatingLabelInput.svelte (1)
180-190: LGTM!The derived class helpers are correctly applied to their respective DOM elements. The bindings properly utilize the reactive class computations.
src/lib/buttons/GradientButton.svelte (2)
13-16: LGTM! Reactive theme pattern correctly implemented.The refactoring to use
$derivedwith inlinegetTheme()calls properly implements reactive theming. The optional chaining provides appropriate safety, and the pattern aligns with the PR's objective to move theme retrieval to derived state.
20-26: LGTM! Template correctly uses derived classes.The template updates properly apply
baseClassandoutlineWrapperClassin both the outline and non-outline rendering branches.src/lib/forms/fileupload/Fileupload.svelte (1)
50-53: Markup correctly uses the derived class constants.The template properly references
wrapperCls,baseCls, andcloseCls, maintaining the component's functionality while adopting the new theming pattern.src/lib/forms/dropzone/Dropzone.svelte (1)
43-43: InlinegetThemecall is reactive but not memoized.The
getTheme("dropzone")call at line 43 accesses reactive theme context viagetThemeContext(), so it will respond to theme changes. However, it is not wrapped in$derivedand will recalculate on every render. SincegetThemeis lightweight (context access + property lookup), this is acceptable for performance. Note that if the PR intended to add memoization via$derived, this would require wrapping the call within a$derivedexpression.Likely an incorrect or invalid review comment.
src/lib/clipboard/Clipboard.svelte (1)
38-41: No action needed. The pattern of callinggetTheme()inside$derivedexpressions is intentional and well-designed. The implementation explicitly supports this:getTheme()accessesgetThemeContext()which is reactive and designed to be called within derived expressions. This same pattern is used consistently across 60+ components throughout the library (Progressbar, Popover, Modal, Navbar, Buttons, and many others), confirming it is the standard approach for theme integration in Flowbite-Svelte.Likely an incorrect or invalid review comment.
src/lib/clipboard-manager/ClipboardManager.svelte (1)
33-33: ClipboardManager should be refactored to use inline getTheme() calls in derived expressions, or explicitly scope this component out of the refactoring.ClipboardManager.svelte still uses the old pattern (
const theme = getTheme("clipboardManager")) while Clipboard.svelte in the same PR has been refactored to inlinegetTheme()calls within$derivedexpressions. This creates inconsistency within related components. However, refactoring ClipboardManager requires addressing 27 theme property accesses throughout the component—significantly more than Clipboard.svelte—which may warrant either:
- Deferring this component to a dedicated refactoring PR
- Accepting this as intentional during phased migration (many other components still use the old pattern)
- Confirming whether mixed patterns are acceptable for this PR's scope
src/lib/modal/Modal.svelte (1)
47-50: Remove the suggested consolidation of getTheme calls—the current pattern is correct.The inline
getTheme("modal")calls within each$derivedstatement on lines 47–50 follow the intended design of the codebase. The$derivedrune expression is re-evaluated whenever its dependencies are updated, and in Svelte 5, $derived computations are lazy—they are only evaluated when their value is actually needed, and when a dependency changes, Svelte marks the $derived value for recalculation upon its next read. ThegetTheme()function is designed to be called within$derivedblocks for reactive theme access, as evidenced by its implementation and the consistent pattern across dozens of components in this codebase (NavUl.svelte, Progressbar.svelte, Popover.svelte, etc.). Consolidating to a singlemodalThemederived introduces an extra indirection layer without performance benefit and deviates from the established pattern.src/lib/forms/textarea/Textarea.svelte (1)
80-106: Theme updates propagate correctly through the derived class pattern.The rendering updates correctly use derived class constants that call
getTheme(). Svelte's $derived tracks synchronous dependencies, and when state changes, the derived will be marked as dirty and recalculated when it is next read. ThemeProvider provides a reactive getter that ensuresgetTheme()accesses the current theme value synchronously within each$derivedexpression, enabling proper reactive propagation when theme changes occur.src/lib/list-group/Listgroup.svelte (1)
11-11: LGTM! Clean inline theme retrieval.The refactor to inline
getTheme("listGroup")directly within the$derivedexpression eliminates the intermediate variable while maintaining the same functionality. The approach is consistent with the broader PR pattern.src/lib/forms/range/Range.svelte (1)
10-10: LGTM! Consistent with the refactoring pattern.The inline
getTheme("range")call properly integrates with the deprecatedinputClassand currentclassNameprops in the class composition.src/lib/forms/label/Label.svelte (1)

29-29: LGTM! Inline theme retrieval properly implemented.The refactor to inline
getTheme("slide")is consistent with the PR's pattern and maintains the same functionality within the derived reactive statement.src/lib/context.ts (1)
77-80: No changes needed — theme context union type is already handled correctly.The single consumer of
getThemeContext()insrc/lib/theme/themeUtils.tsalready uses proper discriminator logic ("value" in themeState) to handle both forms of theThemeContextValueunion type. ThesetThemeContext()call inThemeProvider.sveltecorrectly sets the wrapper object form. No breaking changes exist.Likely an incorrect or invalid review comment.
src/lib/theme/themeUtils.ts (1)
31-77: LGTM! Deprecation warning implementation is well-structured.The
warnThemeDeprecationfunction provides clear migration guidance with helpful examples and stack trace parsing. The implementation correctly:
- Filters only non-empty deprecated props
- Generates contextual migration hints
- Identifies the external caller location
- Only runs in development mode

11-11: LGTM! Inline theme retrieval is correctly applied.The theme retrieval is properly inlined within the
$derivedblock, maintaining reactivity. The change aligns with the PR's objective of moving to derived inline theme values.src/lib/kbd/Kbd.svelte (1)
9-9: LGTM! Theme inlining is correctly implemented.The inline

74-110: LGTM! Template correctly uses derived class constants.The template properly applies the derived class constants (
baseClass,buttonCls,contentCls) to the appropriate elements, maintaining the component's behavior while improving theme reactivity.src/lib/drawer/DrawerHandle.svelte (1)
18-20: LGTM! Derived classes correctly applied.The template properly uses the derived class constants, maintaining component functionality while enabling reactive theming.
src/lib/carousel/ControlButton.svelte (2)
10-14: Good addition of deprecation warning.Properly implemented deprecation warning for the
spanClassprop. This helps guide users toward the newclassespattern.
17-17: Theme usage is correct.Since this component only needs one theme property, a single
getTheme()call is appropriate and efficient.temp-analysis/COMPLETE_FIX_SUMMARY.md (1)
1-157: Excellent documentation of the fix.This summary clearly explains the root cause (calling
setContext()inside$effect()) and the solution (synchronous initialization). The documented limitation about non-reactive theme changes is acceptable, and the provided workarounds using{#key}blocks are appropriate.src/lib/pagination/PaginationItem.svelte (1)
19-19: Theme inlining is appropriate here.Since this component only accesses the theme once, the inline
getTheme()call is efficient and follows the new pattern correctly.src/lib/dropdown/DropdownDivider.svelte (1)
10-10: Theme inlining is appropriate here.Single inline
getTheme()call is efficient and follows the refactored pattern correctly.src/lib/carousel/Thumbnails.svelte (1)
31-31: LGTM!The inline theme retrieval is correctly applied and consistent with the broader refactoring pattern. The change enables reactive theming without affecting the component's throttling or image handling logic.
src/lib/pagination/Pagination.svelte (1)
27-27: LGTM!The theme inlining is correctly implemented within the
$derivedexpression, enabling reactive theme updates while maintaining the existing pagination logic.src/lib/forms/checkbox/CheckboxButton.svelte (1)
11-11: LGTM!The theme inlining follows the established pattern and correctly integrates with the component's bindable props. The change enables reactive theming without affecting checkbox functionality.
src/lib/alert/Alert.svelte (1)
32-32: LGTM!The inline theme retrieval is correctly positioned within the
alert()call, enabling reactive theming while preserving all alert styling variants and dismissable functionality.src/lib/forms/helper/Helper.svelte (1)

src/lib/forms/button-toggle/ButtonToggleGroup.svelte (1)
23-23: LGTM!The theme inlining is correctly applied to the base class derivation without affecting the component's multi-select logic, context setup, or selection state management.
src/lib/navbar/Navbar.svelte (1)
37-37: LGTM!The inline theme retrieval is correctly applied within the
navbar()call, enabling reactive theming while preserving all navbar state management, toggle behavior, and click-outside handling.src/lib/footer/Footer.svelte (1)
9-9: LGTM! Inline theme retrieval is correctly implemented.The inline
getTheme("footer")call within the$derivedblock properly maintains reactivity while simplifying the code structure.src/lib/dropdown/DropdownHeader.svelte (1)
10-10: LGTM! Inline theme retrieval simplifies the code.The direct
getTheme("dropdownHeader")call eliminates an unnecessary intermediate variable.src/lib/drawer/Drawer.svelte (2)
130-130: LGTM! Inline theme retrieval is correctly implemented.The inline
getTheme("drawer")?.basecall properly uses optional chaining and maintains reactivity within the class binding.
136-136: LGTM! Consistent inline theme usage in conditional block.The inline theme retrieval is appropriate here, even though it duplicates the call from line 130, since this block is conditionally rendered and caching wouldn't provide significant benefit.
src/lib/navbar/NavBrand.svelte (1)
10-10: LGTM! Inline theme retrieval eliminates unnecessary intermediate variable.The refactor correctly inlines the theme lookup within the class binding.
src/lib/buttons/Button.svelte (1)
34-34: LGTM! Inline theme retrieval with proper optional chaining.The inline
getTheme("button")?.basecall within the$derivedblock correctly maintains reactivity while using optional chaining to handle undefined themes safely.src/lib/footer/FooterIcon.svelte (1)
11-11: LGTM! Inline theme retrieval simplifies the implementation.The direct
getTheme("footerIcon")call within the conditional block eliminates the intermediate variable while maintaining the same functionality.src/routes/docs/pages/theme-provider.md (3)
15-17: LGTM! Clear explanation of reactive behavior.The "How It Works" section accurately describes the new reactive getter pattern. The explanation that theme changes cause automatic re-rendering aligns well with the ThemeProvider implementation.
177-181: LGTM! Good practical example.The reactive theme example provides a clear demonstration of the new reactive behavior.
190-221: LGTM! Excellent demonstration of dynamic theming.The example correctly demonstrates dynamic theme switching using Svelte 5 runes (
$stateand$derived). The reactive pattern aligns perfectly with the new ThemeProvider implementation.src/lib/carousel/Controls.svelte (1)
22-23: LGTM! Correct usage of new controls theme.The inline
getTheme("controls")calls with optional chaining forpreviousandnextproperties follow the new reactive pattern correctly. The code handles missing themes gracefully.src/lib/carousel/Carousel.svelte (1)
182-183: LGTM! Proper use of derived reactive classes.The
$derivedexpressions correctly compute classes by callinggetTheme("carousel")inline, enabling reactivity through the new getter pattern. Optional chaining ensures safe access.src/lib/badge/Badge.svelte (1)
52-54: LGTM! Consistent inline theme usage.The inline
getTheme("badge")calls with optional chaining correctly implement the new reactive pattern. Both base and linkClass computations will reactively update when theme changes.src/lib/drawer/Drawerhead.svelte (1)
20-23: LGTM! Efficient derived class pattern.The
baseClassis properly computed using$derivedwith inlinegetTheme("drawer")call. This enables reactive updates while precomputing the class string efficiently.src/lib/carousel/index.ts (1)
5-5: LGTM! Proper public export of new controls theme.The
controlsexport is correctly added to the carousel module's public API, enabling the new theme functionality used in Controls.svelte.src/lib/list-group/ListgroupItem.svelte (1)
15-15: LGTM! Clean inline theme integration.The inline
getTheme("listGroupItem")call correctly enables reactive theme tracking. Theclsxfunction handles potential undefined values appropriately.src/lib/theme/ThemeProvider.svelte (1)
13-24: LGTM! Excellent refactor to reactive getter pattern.The new implementation elegantly leverages Svelte 5's fine-grained reactivity:
- The stable object with a reactive getter enables tracking when accessed in child components'
$derivedexpressions- Synchronous
setContextinitialization is more efficient than the previous effect-based approach- The getter pattern automatically propagates theme changes to all consumers
This is a clean solution that aligns with Svelte 5 best practices.
temp-analysis/REACTIVE_FIX.md (1)
1-56: Excellent documentation of the reactive theme pattern.The explanation clearly describes the problem, solution, and mechanism. This will be valuable for developers working with the theme system.
src/lib/forms/toggle/Toggle.svelte (1)
21-31: LGTM! Reactive theme pattern correctly applied.The inline
getTheme("toggle")calls inside each$derivedexpression ensure that class updates will trigger when the theme changes. The element bindings correctly use the derived class constants.src/lib/footer/FooterCopyright.svelte (1)
24-36: LGTM! Reactive theme pattern correctly implemented.The derived class constants properly inline
getTheme("footerCopyright")calls for reactivity. The backward compatibility handling withclassName ?? spanClassis appropriate.src/lib/card/Card.svelte (1)
29-59: LGTM! Well-documented reactive theme implementation.The inline comment on line 29 is helpful for future maintainers. The reactive pattern is correctly applied with
getTheme("card")called inside each$derivedexpression.src/lib/carousel/theme.ts (2)
5-5: LGTM! Type alias follows established pattern.The
ControlButtonVariantstype alias correctly combinesVariantPropsandClassesfor the existingcontrolButtontheme, consistent with theCarouselVariantspattern on line 4.
47-52: Empty slots incontrolsexport are intentional. Thecontrolstheme provides a customization extension point without default classes, delegating button styling to theControlButtoncomponent's owncontrolButtontheme. Users can add custom classes via the theme system if needed, but the default behavior relies on the component-level styling defined incontrolButton.src/lib/forms/checkbox/Checkbox.svelte (2)
38-39: LGTM! Reactive theme pattern correctly applied.The derived class constants properly inline
getTheme("checkbox")calls for reactivity. The pattern is consistently applied to bothdivClsandbaseCls.
69-80: LGTM! Class bindings updated correctly for both rendering paths.The derived class constants are correctly applied to both the choices array iteration (lines 69-70) and the single checkbox case (lines 79-80).
src/lib/footer/FooterLink.svelte (1)
21-26: LGTM! Reactive theme pattern correctly implemented.The derived class constants properly inline
getTheme("footerLink")calls for reactivity. Backward compatibility withclassName ?? liClassis appropriately handled.src/lib/theme/themes.ts (1)
12-12: No action needed. Thecontrolstheme export is actively used in the carousel components.The Controls.svelte component uses
getTheme("controls")?.previousandgetTheme("controls")?.nextto apply theme styling to the previous and next control buttons. Thecontrolstheme is properly defined in the carousel theme file with slots for both controls, and is correctly exported through the carousel module and themes file.src/lib/popover/Popover.svelte (1)
33-36: LGTM - Consistent theme refactoring pattern.The refactoring correctly moves from a stored theme object to derived class constants with inline
getTheme("popover")calls. The multiplegetThemecalls are properly memoized within$derived, so they'll only re-evaluate when the theme context changes.src/lib/bottom-navigation/BottomNavHeader.svelte (1)
20-21: LGTM - Theme derivation follows the refactoring pattern.The changes correctly implement the new theming approach with derived classes computed from inline
getTheme("bottomNavHeader")calls.src/lib/footer/FooterBrand.svelte (2)
13-18: LGTM - Inline theming correctly applied.The href branch correctly applies inline
getTheme("footerBrand")calls for all styled elements.
25-25: Verify theming in the no-href branch.The else branch (when
hrefis not provided) doesn't applygetTheme("footerBrand")?.imgto the image, while the href branch does (line 15). This inconsistency means the image won't receive theme-based styling when rendered without a link.If this is intentional (simplified rendering for non-linked images), consider documenting it. Otherwise, apply this diff to maintain consistent theming:
- <img {src} class={img({ class: clsx(imgClass) })} {alt} /> + <img {src} class={img({ class: clsx(getTheme("footerBrand")?.img, imgClass) })} {alt} />temp-analysis/REACTIVE_IMPLEMENTATION.md (1)
1-123: Documentation explains the reactive pattern well.The document clearly describes the reactive ThemeProvider implementation and provides helpful examples. The technical details about wrapping theme in
$stateand accessing it through context appear sound.src/lib/carousel/CarouselIndicators.svelte (1)
17-28: LGTM - Theme refactoring correctly applied.The component now derives classes inline with
getTheme("carouselIndicators")for both the container (divCls) and indicator elements, following the established refactoring pattern.src/lib/gallery/Gallery.svelte (1)
24-25: LGTM - Consistent with the refactoring pattern.The Gallery component correctly derives image and container classes using inline
getTheme("gallery")calls.src/lib/forms/button-toggle/ButtonToggle.svelte (1)
51-54: LGTM - Multiple derived classes correctly implemented.The ButtonToggle component properly derives four separate class constants (buttonCls, contentCls, iconCls, textCls) with inline
getTheme("buttonToggle")calls, maintaining consistency with the PR's refactoring pattern.src/lib/bottom-navigation/BottomNav.svelte (1)
38-40: LGTM! Clean refactor to derived theme classes.The inline
getTheme()calls within$derivedensure proper reactivity when the theme context changes. The optional chaining withclsxsafely handles undefined theme values.src/lib/breadcrumb/BreadcrumbItem.svelte (1)
17-22: LGTM! Well-structured derived classes for each element variant.The approach of creating separate derived classes for each element type (li, home anchor, link anchor, span, separator) correctly handles the different variant combinations. The
getTheme()calls within$derivedensure reactivity to theme changes.src/routes/docs-examples/pages/theme-provider/ThemeReactive.svelte (1)
94-117: Good demonstration of reactive ThemeProvider usage.The reactive chain from
$state→$derivedthemes →currentTheme→ThemeProvidercorrectly showcases how theme changes propagate to child components. This is a clear example for documentation purposes.src/lib/navbar/NavUl.svelte (1)
63-74: LGTM! Correctly propagates derived theme classes to context.The pattern of computing
activeClsandnonActiveClsvia$derived, then syncing them tonavStatevia$effect, correctly enables childNavLicomponents to access the themed classes. The derived classes at lines 73-74 follow the same inlinegetTheme()pattern consistently.temp-analysis/THEME_PROVIDER_FIX.md (1)
1-102: Clarify implementation status: is full reactivity implemented or deferred?The documentation clearly explains the synchronous context fix and acknowledges a limitation: theme prop changes after initial render won't propagate to child components because
getTheme()is called once at init. However, the PR title mentions "move getTheme to $derived," which typically implies reactive updates.Lines 49-91 describe two optional approaches for full reactivity (reactive wrapper and key-based remounting), but it's unclear whether either has been implemented in the actual code changes or if this is a known limitation of the current fix.
Please clarify:
- Has Option 1 (reactive theme wrapper) been implemented, or is theme reactivity intentionally deferred?
- Does the actual
getTheme()implementation use$derivedas the PR title suggests?- Are the temp-analysis files meant to be committed, or are these draft docs?
temp-analysis/CHANGES.md (1)

Move getTheme call to module scope.
The inline getTheme("bottomNavHeaderItem") call executes on every recalculation of the derived base (triggered by changes to active or className). While getTheme is computationally cheap, this pattern is inconsistent with 108+ other components that correctly call it at module scope. The theme doesn't change dynamically within a component instance, so calling it inside $derived is unnecessary. Move to module scope: const theme = getTheme("bottomNavHeaderItem"); then use theme inside the derived.
This pattern affects 49 components across the PR.

In src/lib/bottom-navigation/BottomNavHeaderItem.svelte around line 9, move the
getTheme("bottomNavHeaderItem") call out of the derived expression to module
scope to avoid re-running it on every derived recomputation: add a module-scope
constant e.g. const theme = getTheme("bottomNavHeaderItem"); then update the
derived to use that theme variable instead of calling getTheme inline (i.e.
replace getTheme("bottomNavHeaderItem") with theme).

Since it need to be reactive, getTheme("xxx"); needs to be inside $derived().

@shinokada, thank you for the clarification! You're absolutely right. I understand now that this PR implements reactive theming where the theme can change dynamically at runtime, and calling getTheme inside $derived() ensures that components automatically re-render when the theme context updates.
The pattern $derived(fn({ class: clsx(getTheme("component"), className) })) correctly establishes reactive dependency on the theme context, which is exactly what's needed for the new reactive ThemeProvider implementation.
I apologize for the incorrect suggestion to move it to module scope—that would have broken the reactivity you're implementing.

Clarify the reactive wrapper pattern and remove unnecessary type assertions.
In Svelte 5, context stores reactive state via $state objects directly accessed through getContext(), not through a .value wrapper. The current implementation's duck typing check ("value" in themeState) suggests an unnecessary wrapper pattern.
Consider this safer implementation that aligns with Svelte 5 standards:
export function getTheme<K extends keyof ThemeConfig>(componentKey: K) {
- // Access the theme context - this will be reactive when called inside $derived
const themeState = getThemeContext();
- // If themeState is a reactive wrapper, access .value, otherwise use it directly
- const theme = themeState && "value" in themeState ? themeState.value : themeState;
-
- // The fix: Assert that `theme` is ThemeConfig or undefined after the conditional check
- const finalTheme = theme as ThemeConfig | undefined;
- return finalTheme?.[componentKey];
+
+ if (!themeState) return undefined;
+ return themeState?.[componentKey];
}Remove the .value wrapper detection unless your ThemeProvider explicitly wraps state with getter/setters. If the theme is stored directly as a $state object (the standard Svelte 5 pattern), the .value check is unnecessary and the type assertion can be removed since themeState already has the correct type.
Verify that your ThemeProvider stores the theme config directly via setContext('theme', themeConfig) without an additional wrapper layer.

In src/lib/theme/themeUtils.ts around lines 6 to 15, the current code duck-types
for a `.value` reactive wrapper and uses an unnecessary type assertion which is
not the Svelte 5 pattern; remove the `"value" in themeState` branch and the `as
ThemeConfig | undefined` cast, treat getThemeContext() result as the theme
directly (possibly undefined), and just return themeState?.[componentKey];
ensure the ThemeProvider uses setContext('theme', themeConfig) with the raw
ThemeConfig (no wrapper) or update this util if you intentionally use a custom
wrapper.

@shinokada, I apologize for the confusion! My suggestion was incorrect. Could you please share what error you're seeing? This will help me understand the issue better.
Based on the AI summary mentioning that src/lib/context.ts was updated to use a ThemeContextValue wrapper type, it appears the .value check IS intentional for the reactive wrapper pattern. Let me look at the context type definitions to provide a better solution.
🏁 Script executed:
#!/bin/bash
# Check the context.ts file to see the ThemeContextValue type definition
cat src/lib/context.ts
Length of output: 3938
@shinokada, I now understand why my suggestion was incorrect. After reviewing src/lib/context.ts, I can see the intentional design:
type ThemeContextValue = ThemeConfig | { value?: ThemeConfig };Your implementation correctly handles both cases of this union type:
- Direct ThemeConfig: When the theme is stored directly in context
- Reactive wrapper: When the theme is wrapped in
{ value?: ThemeConfig }for reactivity
The current code is correct:
const theme = themeState && "value" in themeState ? themeState.value : themeState;
const finalTheme = theme as ThemeConfig | undefined;Why the type assertion is necessary:
After the conditional check, TypeScript still sees theme as ThemeConfig | { value?: ThemeConfig } | undefined. Without the type assertion, accessing theme?.[componentKey] would fail because TypeScript can't index the wrapper object type with componentKey. The assertion correctly narrows it to ThemeConfig | undefined after extracting the value.
I apologize for the confusion. Your implementation is correct and handles the reactive wrapper pattern properly. My suggestion should be disregarded.

Clarify documentation contradiction about {#key} necessity for theme switching.
MIGRATION_GUIDE.md recommends {#key} as Pattern 1 (the primary approach) for dynamic theme switching. However, REACTIVE_IMPLEMENTATION.md explicitly states that "{#key} block is no longer needed" and that "no {#key} blocks or remounting needed" because ThemeProvider is "fully reactive."
If the implementation is truly fully reactive without {#key} blocks, the migration guide should not position {#key} as the recommended primary pattern. The docs need alignment on whether:
{#key}is necessary for theme switching (in which caseREACTIVE_IMPLEMENTATION.mdshould be updated){#key}is unnecessary due to full reactivity (in which case Pattern 1 inMIGRATION_GUIDE.mdshould reflect this or be deprioritized)

In temp-analysis/MIGRATION_GUIDE.md around line 95, the $derived rune is used
without a variable declaration causing invalid Svelte 5 syntax; fix it by adding
a declaration keyword before the rune (e.g., change the line to start with "let
$derived theme = ..." or "const $derived theme = ..." depending on mutability)
so the $derived is declared as a variable rather than used as a bare expression.

10-32: Consider consolidatinggetTheme("skeleton")into a single derived expression.Each of the seven derived class bindings independently calls
getTheme("skeleton"), resulting in redundant function invocations on every reactive update. Deriving the theme once and referencing it across all class bindings would improve efficiency and maintainability.Apply this refactor:

57-69: LGTM! Template correctly uses derived classes.The template properly applies all derived class constants to their respective elements. The conditional rendering logic and style bindings are correct.
Optional: Consider restProps spreading pattern.
Lines 57 and 62 both spread
{...restProps}. WhenlabelOutsideis truthy, both the label container and progress bar receive the same attributes. IfrestPropscontains unique identifiers (e.g.,id,data-testid), this could cause issues. Consider whether the label container (line 57) should receive separate props or ifrestPropsshould only apply to the progress bar (line 62).Note: This is a pre-existing pattern, not introduced by this PR.

Learning: When using ThemeProvider with reactive themes in Flowbite-Svelte, ensure that getTheme("componentName") calls are placed inside a $derived() expression (not at module scope) so components react to dynamic theme changes. This applies broadly to Svelte components in this repo that rely on theme-derived values. For example:
// bad: at module scope
const theme = getTheme("button");
// good: inside a derived store
import { derived } from 'svelte/store';
const themeDerived = derived(themeProviderStore, ($themeProvider) => getTheme("button"));
// use $themeDerived in template/component

6-13: LGTM! Reactive wrapper pattern correctly handles both context shapes.The duck-typing check for
"value" in themeStateproperly supports theThemeContextValueunion type (ThemeConfig | { value?: ThemeConfig }), and the type assertion is necessary to satisfy TypeScript after the conditional extraction. This aligns with the reactive theming pattern where consumers callgetTheme()inside$derived()expressions.

36-41: Good fix for the dynamic Tailwind class issue.The
colorClassesmapping with complete class strings ensures Tailwind can detect these classes during static analysis. This properly addresses the previous review concern about dynamically constructed classes being purged.
10-31: Reactive theme derivation is well-structured.The
$derivedthemes object correctly recomputes whenbuttonWidthchanges. The Tailwind classes are safe because:
- Width classes (
w-32,w-48,w-64) appear as complete string literals elsewhere in the file (lines 71-73)- Color classes are written as complete strings, not interpolated
90-109: ThemeProvider integration looks correct.The
currentThemederived state is properly passed toThemeProvider, and nestedButtonandCardcomponents will receive theme overrides. The reactive chain (buttonWidth→themes→currentTheme→ ThemeProvider) ensures immediate updates when selections change.src/lib/skeleton/Skeleton.svelte (1)
35-42: LGTM!The template correctly applies all derived class bindings. The reuse of
lineCls3on lines 38-39 appears intentional for the skeleton loading pattern.src/lib/progress/Progressbar.svelte (2)
30-42: LGTM! Correct reactive theme function derivation.The destructuring of theme functions within
$derived()ensures they react tocolorandlabelInsideprop changes. This is the correct pattern for reactive theming in Flowbite-Svelte.Based on learnings, this pattern ensures components react to dynamic theme changes.
44-49: LGTM! Correctly implements reactive theme composition.Each derived class correctly:
- Wraps
getTheme("progressbar")inside$derived()for reactive theme updates.- Composes theme classes with custom classes using
clsx.- Includes
sizeonly for progress bar elements (lines 47-49), not label-outside elements (lines 44-46), which is semantically appropriate.The multiple
getThemecalls ensure each derived class updates independently when the theme changes.Based on learnings, this pattern ensures components react to dynamic theme changes.
