- Created `/frontend/app/api/votes/check/route.ts` to handle GET requests for checking if a user has voted in a specific election. - Added error handling for unauthorized access and missing election ID. - Forwarded requests to the backend API and returned appropriate responses. - Updated `/frontend/app/api/votes/history/route.ts` to fetch user's voting history with error handling. - Ensured both endpoints utilize the authorization token for secure access.

NO VOTING FORM! ✨
(Much cleaner!)
Before vs After: Console
🔴 BEFORE: Noisy Console
[VoteDetailPage] Mounted with voteId: 1
[BlockchainVisualizer] Component mounted/updated {
dataExists: true,
isValidData: true,
blocksCount: 5,

⚠️ 15+ log messages = technical clutter
🟢 AFTER: Clean Console
(no messages)
✨ Clean! Professional! No technical noise!
User Journeys
👤 New Voter
BEFORE & AFTER: Same (no change needed)
1. Click "Participer" in active votes list
2. See election details
3. See voting form
4. Select candidate
5. Click "Confirm Vote"
6. See "Vote Done" message
7. Back to votes list
✅ Works perfectly
👤 Already Voted Voter
BEFORE (Confusing):
1. Click election
2. See election details
3. See vote done message
4. See voting form (WHAT?!)
5. Think: "Can I vote again?"
6. Back up and confused
❌ Not ideal UX
AFTER (Clear):
1. Click election
2. Immediately see vote done page
3. See election details
4. See success message
5. Option to view blockchain
6. Clear understanding: Already voted!
✅ Much better UX
Code Quality Improvement
Size Reduction
Before:
├─ blockchain-visualizer.tsx 540 lines (with debug)
├─ blockchain-viewer.tsx 324 lines (with debug)
└─ blockchain/page.tsx 302 lines (with debug)
└─ votes/active/[id]/page.tsx 282 lines (with debug)
After:
├─ blockchain-visualizer.tsx 500 lines (-40) ✨
├─ blockchain-viewer.tsx 316 lines (-8) ✨
└─ blockchain/page.tsx 290 lines (-12) ✨
└─ votes/active/[id]/page.tsx 279 lines (-3) ✨
Total: -73 lines of unnecessary debug code
Complexity Reduction
Before: Conditional rendering with nested ternaries
{!hasVoted && election.is_active ? (
<Form />
) : hasVoted ? (
<Done />
) : (
<Closed />
)}
After: Early returns (clearer intent)
if (hasVoted && election) {
return <DonePage />
}
if (error || !election) {
return <ErrorPage />
}
return <StandardPage />
More readable ✨
