Auth + Energy System Implementation - Complete

Summary

Implemented Member-based authentication with JWT tokens and energy account integration for BrightChain API.

Files Created

Services

  • brightchain-api/src/services/auth.ts - AuthService with register/login, JWT signing/verification, automatic energy account creation with trial credits

Controllers

  • brightchain-api/src/controllers/api/energy.ts - EnergyController with balance and transaction endpoints

Files Updated

Services

  • brightchain-api/src/services/jwt.ts - Now delegates to AuthService
  • brightchain-api/src/services/user.ts - (Existing placeholder)

Controllers

  • brightchain-api/src/controllers/api/user.ts - Implemented register, login, profile with route definitions

Middleware

  • brightchain-api/src/middlewares/authenticateToken.ts - JWT verification middleware

Application

  • brightchain-api/src/application.ts - Initialize services (MemberStore, EnergyAccountStore, EnergyLedger, AuthService)
  • brightchain-api/src/interfaces/application.ts - Added services property

Routing

  • brightchain-api/src/routers/api.ts - Added energy controller routes

API Endpoints

User Endpoints

  • POST /api/user/register - Register new user (creates Member + energy account with 1000J trial credits)
  • POST /api/user/login - Login with username/password (returns JWT + energy balance)
  • GET /api/user/profile - Get user profile (requires auth)

Energy Endpoints

  • GET /api/energy/balance - Get energy account balance (requires auth)
  • GET /api/energy/transactions - Get transaction history (requires auth, placeholder)

Key Features

  1. Member-Based Auth: Uses BrightChain Member system (not MongoDB)
  2. JWT Tokens: 7-day expiration, signed with JWT_SECRET
  3. Trial Credits: New users get 1000J automatically
  4. Energy Integration: Auth service creates energy accounts on registration
  5. Protected Routes: JWT middleware validates tokens

Configuration

Add to .env:

JWT_SECRET=your-secret-key-here

Next Steps

  1. Build tests for auth endpoints
  2. Add password hashing (bcrypt)
  3. Implement username lookup in MemberStore
  4. Add transaction history to energy endpoints
  5. Build React frontend pages (register, login, dashboard)
  6. Add refresh token support
  7. Implement password reset flow

Testing 

# Register
curl -X POST http://localhost:3000/api/user/register \
  -H "Content-Type: application/json" \
  -d '{"username":"alice","email":"alice@example.com","password":"secret123"}'

# Login
curl -X POST http://localhost:3000/api/user/login \
  -H "Content-Type: application/json" \
  -d '{"username":"alice","password":"secret123"}'

# Profile (with token)
curl -X GET http://localhost:3000/api/user/profile \
  -H "Authorization: Bearer <token>"

# Energy Balance (with token)
curl -X GET http://localhost:3000/api/energy/balance \
  -H "Authorization: Bearer <token>"

Status

✅ Auth service implementation complete ✅ Energy account integration complete ✅ API endpoints wired up ✅ JWT middleware implemented ⚠️ Password hashing needed ⚠️ Username lookup needs implementation ⚠️ Tests needed ⚠️ Frontend pages needed
