Implementation Workflow

Step 1: Review Architecture (30 min)

1. Start with AUTH_QUICK_REFERENCE.md - understand basics
2. Read AUTH_ANALYSIS_SUMMARY.md - understand decisions
3. Skim AUTH_ARCHITECTURE_REPORT.md sections 1-4

Step 2: Plan Integration (15 min)

1. Read AUTH_VALIDATION_CHECKLIST.md Pre-Integration section
2. Determine integration path (A or B)
3. Set up environment variables

Step 3: Implement (2-3 hours)

1. Reference AUTH_ARCHITECTURE_REPORT.md Section 9
2. Follow AUTH_VALIDATION_CHECKLIST.md Implementation section
3. Use code examples from Quick Reference

Step 4: Test (1-2 hours)

1. Follow AUTH_VALIDATION_CHECKLIST.md Testing section
2. Use curl commands from Quick Reference
3. Verify development bypass works

Step 5: Validate (30 min)

1. Complete AUTH_VALIDATION_CHECKLIST.md all sections
2. Get code review approval
3. Sign off checklist

Key Findings Summary

Central Service

• Name: mana-core-auth
• Port: 3001
• Framework: NestJS + Better Auth
• Algorithm: EdDSA JWT
• Database: PostgreSQL with Drizzle

Integration Patterns

• Path A: @manacore/shared-nestjs-auth (lightweight)
• Path B: @mana-core/nestjs-integration (with credits)
• Pattern: Centralized validation via /api/v1/auth/validate

Canonical Design

• JWT Claims: Minimal (sub, email, role, sid only)
• Token Expiry: 15 minutes (access), 7 days (refresh)
• Rotation: Refresh token rotation + soft delete
• Guards: Use @UseGuards() decorator
• Injection: Use @CurrentUser() decorator

Environment Setup

# Required
MANA_CORE_AUTH_URL=http://localhost:3001

# Development (optional)
NODE_ENV=development
DEV_BYPASS_AUTH=true
DEV_USER_ID=test-uuid

# Better Auth manages JWT (DO NOT SET)
# JWT_PRIVATE_KEY=...
# JWT_PUBLIC_KEY=...

Architecture Decisions (Validated)

1. Minimal JWT Claims

   • Why: Prevents stale data (credits, org info change frequently)
   • Impact: Smaller tokens, better performance
   • Evidence: All backends follow pattern

2. EdDSA Algorithm

   • Why: Better performance + security than RSA
   • Impact: Smaller keys (32 bytes vs 2048+ bits)
   • Source: Better Auth framework default

3. Centralized Validation

   • Why: Single source of truth, reduces key distribution
   • Impact: All backends call /api/v1/auth/validate
   • Benefit: Easier security updates

4. Refresh Token Rotation

   • Why: Prevent token replay attacks
   • Impact: Old token revoked on refresh
   • Result: Enhanced session security

---

Common Mistakes (Avoid!)

1. Wrong JWT Algorithm

   • WRONG: RS256 or HS256
   • RIGHT: EdDSA (Better Auth default)

2. Hardcoded Claims

   • WRONG: Adding org data, credits to JWT
   • RIGHT: Fetch via API endpoints

3. Missing Guard

   • WRONG: Manual token parsing in controllers
   • RIGHT: Use @UseGuards() decorator

4. Wrong Library

   • WRONG: import jwt from 'jsonwebtoken'
   • RIGHT: Use jose library for verification

5. Environment Variable

   • WRONG: Setting JWT_PRIVATE_KEY
   • RIGHT: Let Better Auth manage keys

See AUTH_ARCHITECTURE_REPORT.md Section 10 for troubleshooting guide.

Testing Quick Commands

Get Token

curl -X POST http://localhost:3001/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email": "test@example.com", "password": "password123"}'

Test Protected Endpoint

curl http://localhost:3007/api/favorites \
  -H "Authorization: Bearer $TOKEN"

Validate Token

curl -X POST http://localhost:3001/api/v1/auth/validate \
  -H "Content-Type: application/json" \
  -d "{\"token\": \"$TOKEN\"}"

Decode Token

echo $TOKEN | cut -d'.' -f2 | base64 -d | jq '.'

More commands in AUTH_QUICK_REFERENCE.md.

Integration Checklist (TL;DR)

• Choose integration path (A or B)
• Set MANA_CORE_AUTH_URL=http://localhost:3001
• Install package via pnpm
• Add guard to main.ts
• Use @UseGuards() on controllers
• Use @CurrentUser() in handlers
• Mark public routes with @Public() (Path B)
• Test with token
• Enable dev bypass (NODE_ENV=development, DEV_BYPASS_AUTH=true)
• Complete AUTH_VALIDATION_CHECKLIST.md
• Get code review
• Deploy
