21-26: Consider consolidating font-family declarationsThe
font-familydeclaration in thebodyselector overrides the more comprehensive font stack defined in:root. Consider removing thefont-familyfrombodyto maintain consistency and better fallback options.body { - font-family: Arial, sans-serif; min-height: 100dvh; margin: 0; padding: 0; }
417-445: Consider adopting a more systematic layout approachThe current layout system mixes various approaches. Consider:
- Using CSS Grid for the card layout system
- Implementing a consistent spacing scale
- Reducing specificity with utility classes
Consider implementing a spacing scale system:
:root { --spacing-xs: 0.25rem; --spacing-sm: 0.5rem; --spacing-md: 1rem; --spacing-lg: 2rem; --spacing-xl: 4rem; }src/admin/utils.ts (1)
29-49: Improve type safety and array handling in deepEqualThe function has two potential improvements:
- Use more specific types instead of
any- Add specific handling for arrays to ensure order-sensitive comparison
-export const deepEqual = (a: any, b: any): boolean => { +export const deepEqual = <T>(a: T, b: T): boolean => { if (a === b) return true; if ( typeof a !== "object" || a === null || typeof b !== "object" || b === null ) return false; + + // Handle arrays + if (Array.isArray(a) && Array.isArray(b)) { + if (a.length !== b.length) return false; + return a.every((item, index) => deepEqual(item, b[index])); + } const keysA: string[] = Object.keys(a); const keysB: string[] = Object.keys(b);src/admin/index.jsx (1)

window.innerWidthmultiple times. Consider extracting this into a custom hook for better performance and maintainability.+const useWindowSize = () => { + const [width, setWidth] = React.useState(window.innerWidth); + + React.useEffect(() => { + const handleResize = () => setWidth(window.innerWidth); + window.addEventListener('resize', handleResize); + return () => window.removeEventListener('resize', handleResize); + }, []); + + return width; +}; export default function Admin() { const [authUser, setAuthUser] = React.useState(false); const [loading, setLoading] = React.useState(true); - const [open, setOpen] = React.useState(window.innerWidth > 840); + const width = useWindowSize(); + const [open, setOpen] = React.useState(width > 840);src/admin/vote/Edit.jsx (3)

82-117: Improve error handling and avoid potential race conditionsThe update function has several areas for improvement:
- Option deletion should be handled atomically
- Error handling could be more specific
- The function has multiple responsibilities

365-389: Enhance loader function with input validation and error handlingThe loader function could be improved with better input validation and more specific error handling.
Edit.loader = async function loader({ params }) { try { const { id } = params; + if (!id || typeof id !== 'string') { + throw new Error('Invalid vote ID'); + } + const vote = await getDoc(doc(db, `/votes/${id}`)); if (!vote.exists()) { - throw new Error(`Vote with id ${id} not found`); + const error = new Error(`Vote with id ${id} not found`); + error.code = 'NOT_FOUND'; + throw error; } const voteData = { id, ...vote.data() }; const options = await getDocs(collection(db, `/votes/${id}/options`)); const optionData = options.docs.map((doc) => ({ id: doc.id, ...doc.data(), })); return { vote: voteData, options: optionData, }; } catch (error) { - console.error("Failed to load vote:", error); + const isNotFound = error.code === 'NOT_FOUND'; + console.error(`Failed to ${isNotFound ? 'find' : 'load'} vote:`, error); throw error; } };src/Vote.jsx (2)
53-59: Simplify navigation logicThe navigation logic could be more straightforward and easier to maintain.
- if (localStorage.getItem(id) && !urlParams.get("preview")) { - if (urlParams.get("allowResubmission")) { - navigate(`/x/${id}?allowResubmission=true`); - return; - } - navigate(`/x/${id}`); - } + const hasVoted = localStorage.getItem(id); + const isPreview = urlParams.get("preview"); + const allowResubmission = urlParams.get("allowResubmission"); + + if (hasVoted && !isPreview) { + navigate(`/x/${id}${allowResubmission ? '?allowResubmission=true' : ''}`); + }

324-343: Simplify card styling logicThe conditional styling logic is complex and could be made more maintainable.
Consider extracting the styling logic into a separate function:

438-440: Verify MDUI color variable dependency
The .option-card.selected class uses an undefined CSS variable --mdui-color-primary. Please ensure this variable is properly defined in your design system or consider using a fallback color.
src/admin/utils.ts (1)
59-70: LGTM!
The implementation correctly handles word capitalization, including special cases for German umlauts and hyphenated words.
src/Vote.jsx (2)
16-16: LGTM: Good addition of input formatting utility
The addition of the capitalizeWords utility function import helps ensure consistent name formatting across the application.
Line range hint 1-424: Verify edge cases in voting functionality
Please ensure the component handles these scenarios correctly:
- Multiple simultaneous votes
- Network disconnections during submission
- Browser refresh during voting
✅ Verification successful
Based on the shell script results, I can now generate the final response:
Edge cases are properly handled in the voting component
The code implements robust error handling and state management:
- Network errors during submission are caught and user-friendly messages are displayed
- Browser state is preserved via localStorage to prevent duplicate submissions
- Race conditions are mitigated by using Firebase's atomic operations
- Component cleanup is handled through useEffect's cleanup function
The only minor suggestion would be to add a loading state indicator during the initial render to prevent flash of content.
Reasoning:
- The code handles network disconnections with specific error messages for "Network Error" and "permission-denied" cases
- Browser refresh/navigation is handled via localStorage check:
if (localStorage.getItem(id) && !urlParams.get("preview")) - Concurrent votes are safely handled by Firebase's atomic
addDocoperation - The component properly manages state with React hooks and includes proper cleanup in useEffect
- Error boundaries weren't found but they're not critical here as the component has its own error handling
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check for proper handling of concurrent votes and race conditions
ast-grep --pattern 'addDoc(collection(db, $_), $_)'
# Check for proper cleanup on unmount
ast-grep --pattern 'React.useEffect($_, $_)'
# Check for proper error boundary implementation
ast-grep --pattern 'class $_ extends React.Component { componentDidCatch($_, $_) }'
