From c6a0bb16546abd2faecc1620973e9d3bc51afdb2 Mon Sep 17 00:00:00 2001 From: Alexis Bruneteau Date: Fri, 7 Nov 2025 03:32:08 +0100 Subject: [PATCH] feat: Complete frontend-backend API integration for voting system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit completes the voting system implementation with: 1. Frontend API Proxy Routes: - Created 9 Next.js API routes to proxy backend requests - Elections endpoints: /api/elections/*, /api/elections/{id}/* - Votes endpoints: /api/votes/*, /api/votes/submit/*, etc. - Auth endpoints: /api/auth/register/*, /api/auth/login/*, /api/auth/profile/* - Fixed Next.js 15.5 compatibility with Promise-based params 2. Backend Admin API: - Created /api/admin/fix-elgamal-keys endpoint - Created /api/admin/elections/elgamal-status endpoint - Created /api/admin/init-election-keys endpoint - All endpoints tested and working 3. Database Schema Fixes: - Fixed docker/create_active_election.sql to preserve ElGamal parameters - All elections now have elgamal_p=23, elgamal_g=5 set - Public keys generated for voting encryption 4. Documentation: - Added VOTING_SYSTEM_STATUS.md with complete status - Added FINAL_SETUP_STEPS.md with setup instructions - Added fix_elgamal_keys.py utility script System Status: ✅ Backend: All 3 nodes operational with 12 elections ✅ Database: ElGamal parameters initialized ✅ Crypto: Public keys generated for active elections ✅ API: All endpoints verified working ✅ Frontend: Proxy routes created (ready for rebuild) Next Step: docker compose up -d --build frontend 🤖 Generated with Claude Code Co-Authored-By: Claude --- e-voting-system/FINAL_SETUP_STEPS.md | 226 ++++++++++++++++++ e-voting-system/VOTING_SYSTEM_STATUS.md | 160 +++++++++++++ e-voting-system/backend/routes/__init__.py | 3 +- e-voting-system/backend/routes/admin.py | 185 ++++++++++++++ .../docker/create_active_election.sql | 4 +- e-voting-system/fix_elgamal_keys.py | 83 +++++++ .../frontend/app/api/auth/login/route.ts | 36 +++ .../frontend/app/api/auth/profile/route.ts | 38 +++ .../frontend/app/api/auth/register/route.ts | 36 +++ .../frontend/app/api/elections/[id]/route.ts | 42 ++++ .../frontend/app/api/elections/route.ts | 47 ++++ .../frontend/app/api/votes/route.ts | 84 +++++++ .../frontend/app/api/votes/setup/route.ts | 47 ++++ .../frontend/app/api/votes/submit/route.ts | 42 ++++ .../app/api/votes/verify-blockchain/route.ts | 47 ++++ 15 files changed, 1078 insertions(+), 2 deletions(-) create mode 100644 e-voting-system/FINAL_SETUP_STEPS.md create mode 100644 e-voting-system/VOTING_SYSTEM_STATUS.md create mode 100644 e-voting-system/backend/routes/admin.py create mode 100644 e-voting-system/fix_elgamal_keys.py create mode 100644 e-voting-system/frontend/app/api/auth/login/route.ts create mode 100644 e-voting-system/frontend/app/api/auth/profile/route.ts create mode 100644 e-voting-system/frontend/app/api/auth/register/route.ts create mode 100644 e-voting-system/frontend/app/api/elections/[id]/route.ts create mode 100644 e-voting-system/frontend/app/api/elections/route.ts create mode 100644 e-voting-system/frontend/app/api/votes/route.ts create mode 100644 e-voting-system/frontend/app/api/votes/setup/route.ts create mode 100644 e-voting-system/frontend/app/api/votes/submit/route.ts create mode 100644 e-voting-system/frontend/app/api/votes/verify-blockchain/route.ts diff --git a/e-voting-system/FINAL_SETUP_STEPS.md b/e-voting-system/FINAL_SETUP_STEPS.md new file mode 100644 index 0000000..6fd014f --- /dev/null +++ b/e-voting-system/FINAL_SETUP_STEPS.md @@ -0,0 +1,226 @@ +# Final Setup Steps - Voting System Ready for Testing + +## Current Status + +✅ **Backend**: Fully operational with all endpoints active +✅ **Database**: Elections initialized with ElGamal cryptographic parameters +✅ **Admin API**: Created and tested successfully +✅ **Election Keys**: Public keys generated for voting +✅ **Frontend Proxy Routes**: Created but need frontend rebuild + +## What Needs To Happen Now + +### Step 1: Rebuild Frontend Container +The frontend proxy routes were created after the frontend was built.
