Extract the credit system from mana-core-auth into a standalone service.
Uses Hono framework on Bun runtime instead of NestJS.
Service includes:
- Personal credit balance with optimistic locking
- Immutable transaction ledger
- Stripe payment integration (PaymentIntents, Checkout Sessions)
- Guild shared pools with per-member spending limits
- Gift code system (simple, personalized, split, first_come, riddle)
- Service-to-service internal API (X-Service-Key auth)
- JWT validation via JWKS from mana-core-auth (jose library)
Architecture:
- 27 files, ~2.2k LOC (vs ~4.1k in NestJS)
- Drizzle ORM schemas adapted for standalone DB (no FK to auth tables)
- Zod validation instead of class-validator
- Manual service instantiation instead of NestJS DI
- Hono middleware for JWT + service key auth
Port: 3060
Database: mana_credits (separate from mana_auth)
Next steps: Update CreditClientService URL, update mana-core-auth
registration hooks, configure Docker + Cloudflare Tunnel.
