Next.js API Integration for Universal Deployment#22
Open
Conversation
…ation
🔧 Problem Solved:
- View Proof functionality was broken for all users
- Frontend was trying direct Golem DB connection (browser limitations)
- No universal solution for accessing verification data
✅ Solution Implemented:
- Updated frontend to use backend API with environment variable configuration
- Added NEXT_PUBLIC_API_BASE_URL for flexible deployment
- Enhanced golem_endpoints.py with proper fetch functions
- Added /golem-verification/{user_id} endpoint to biometrics server
🚀 Deployment Ready:
- Local development: Uses http://localhost:8001 (existing service)
- Production: Uses NEXT_PUBLIC_API_BASE_URL environment variable
- Backend service: golem-endpoints on port 8001
- Required env vars: PRIVATE_KEY, GOLEM_DB_RPC, GOLEM_DB_WSS, GOLEM_APP_TAG
📊 Verified Working:
- API endpoint: /api/v1/verification-by-user/{user_id}
- Returns real Golem DB data with all annotations
- Entity keys, humanity scores, timestamps all working
- Source: golem_db ✅
Ready for Kubernetes deployment! 🎉
…ment - Add Next.js API route /api/verification-by-user/[userId] - Install golem-base-sdk in frontend project - Update verification-hero.tsx to call local API - Ready for Vercel deployment with environment variables - Fixes View Proof functionality for all users

Unrestricted console logging in production may leak identifiers and clutter logs; gate these logs behind a dev check or remove them.

Comparing timestamp strings can return the wrong latest record; parse to datetime for reliable ordering.

Use the error logger instead of print to capture exceptions in logs.

This endpoint re-implements logic that already exists in golem_endpoints.fetch_verification_by_user_id; prefer calling the shared function to avoid duplication and divergence.
