7-16: Consider enhancing type safety and validation.While the types are well-defined, consider these improvements:
- Add non-empty array validation for options
- Make value and label properties more specific if possible
- Add runtime validation for empty options array
Consider this enhancement:
type Option = { - label: string; - value: string; + label: string; // Consider readonly if immutable + value: string; // Consider union type if values are known }; type MultiSelectProps = { - options: Option[]; + options: readonly Option[] & { length: number }; // Ensures non-empty array selectedValues?: string[]; onChange: (values: string[]) => void; };
21-38: Enhance event handlers with error handling and performance optimizations.The handlers work well but could be more robust:
- Add error handling for onChange callback
- Consider debouncing for rapid changes
- Add error boundary for component safety
Consider these improvements:
+const handleChange = useCallback((newSelected: string[]) => { + try { + onChange(newSelected); + } catch (error) { + console.error('Error in onChange callback:', error); + } +}, [onChange]); + +const debouncedHandleChange = useMemo( + () => debounce(handleChange, 100), + [handleChange] +); + const handleToggle = (value: string) => { setSelected((prevSelected) => { const newSelected = prevSelected.includes(value) ? prevSelected.filter((v) => v !== value) : [...prevSelected, value]; - onChange(newSelected); + debouncedHandleChange(newSelected); return newSelected; }); };

1-6: LGTM! Proper imports and licensing.
The file header includes appropriate licensing and the imports are correctly structured.
63-63: LGTM! Clear and explicit export.
The named export is appropriate for this component.

🛠️ Refactor suggestion
Enhance accessibility and performance for large lists.
The component is accessible but could be improved:
- Add loading state
- Consider virtualization for large lists
- Enhance ARIA labels
Consider these improvements:
return (
<div className="multi-select" role="listbox" aria-multiselectable="true" aria-label="Multi-select list">
+ {options.length === 0 && (
+ <div className="empty-state" role="alert">
+ No options available
+ </div>
+ )}
{options.map((option) => {
const isSelected = selected.includes(option.value);
return (
<div
key={option.value}
role="option"
aria-selected={isSelected}
+ aria-label={`${option.label}${isSelected ? ' selected' : ''}`}
className={`option ${isSelected ? "selected" : ""}`}
tabIndex={0}
onClick={() => handleToggle(option.value)}
onKeyDown={(e) => handleKeyDown(e, option.value)}
>
{option.label}
{isSelected && <i className="fa fa-solid fa-check" aria-hidden="true" />}
</div>
);
})}
</div>
);For large lists, consider using a virtualization library:
import { FixedSizeList } from 'react-window';

🛠️ Refactor suggestion
Add synchronization with prop changes and validation.
The component should sync its internal state when selectedValues prop changes and validate for duplicate values.
Add this code after the useState declaration:
const [selected, setSelected] = useState<string[]>(selectedValues);
+
+// Sync with prop changes
+useEffect(() => {
+ setSelected(selectedValues);
+}, [selectedValues]);
+
+// Validate props
+useEffect(() => {
+ const uniqueValues = new Set(selectedValues);
+ if (uniqueValues.size !== selectedValues.length) {
+ console.warn('MultiSelect: selectedValues contains duplicate values');
+ }
+}, [selectedValues]);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

💡 Codebase verification
Add unit tests for the MultiSelect component
The component has good documentation through Storybook stories that demonstrate its usage with proper prop descriptions and examples. However, it lacks unit tests to verify its functionality. Please add tests to cover:
- Initial rendering with and without selected values
- Option selection/deselection behavior
- Keyboard interaction (Enter and Space key handlers)
- Callback invocation with updated values
🔗 Analysis chain
Verify component documentation and test coverage.
Let's ensure the component is properly documented and tested.
Let me check the content of the stories file to verify the documentation quality.
