|
|
- Full IntelliSense support
|
|
- Compile-time validation
|
|
|
|
2. **Database Adapter System**
|
|
- Supports Drizzle, Prisma, TypeORM
|
|
- Automatic schema generation
|
|
- Built-in migration support
|
|
|
|
3. **Plugin Architecture**

|
|
- Third-party ecosystem growing
|
|
- Easy to extend
|
|
|
|
4. **Framework Agnostic**

|
|
- Backend agnostic (NestJS, Express, Hono)
|
|
- Perfect for monorepos
|
|
|
|
### PostgreSQL RLS Insights
|
|
|
|
1. **Defense in Depth**
|
|
- Even if application code has bugs, database enforces isolation
|
|
- Policies apply at database level
|
|
- Cannot be bypassed by application
|
|
|
|
2. **Performance**
|
|
- Minimal overhead with proper indexing
|
|
- tenant_id indexes are critical
|
|
- Composite indexes for query patterns
|
|
|
|
3. **Testing is Critical**
|
|
- Must test all access patterns
|
|
- Integration tests for each policy
|
|
- Verify cross-tenant isolation
|
|
|
|
### Credit System Best Practices
|
|
|
|
1. **Double-Entry Ledger**
|
|
- Every transaction creates debit + credit entries
|
|
- Mathematical proof of accuracy
|
|
- Complete audit trail
|
|
|
|
2. **Idempotency**
|
|
- Prevents duplicate charges
|
|
- Safe to retry failed requests
|
|
- Industry standard pattern
|
|
|
|
3. **DECIMAL for Money**
|
|
- Never use FLOAT for monetary values
|
|
- DECIMAL ensures precision
|
|
- No rounding errors
|

## ❓ Questions for Team
|
|
|
|
### Product Questions
|
|
|
|
1. **Credit Pricing**
|
|
- What should credit packages cost?
|
|
- Suggested: 100 credits for $9.99, 500 for $39.99, etc.
|
|
|
|
2. **Credit Expiration**
|
|
- Should credits expire? If so, after how long?
|
|
- Recommendation: 90 days for purchased, no expiration for bonus
|
|
|
|
3. **Subscription Model**
|
|
- Offer monthly subscriptions or pay-as-you-go only?
|
|
- Recommendation: Start with pay-as-you-go, add subscriptions later
|
|
|
|
4. **OAuth Providers**
|
|
- Which social login providers are required?
|
|
- Recommendation: Google, GitHub, Apple (for iOS)
|
|
|
|
### Technical Questions
|
|
|
|
5. **Multi-Tenancy Priority**
|
|
- Are organizations/teams a priority feature?
|
|
- Better Auth supports this, but adds complexity
|
|
|
|
6. **Compliance Requirements**
|
|
- Any specific compliance needs? (GDPR, HIPAA, SOC 2)
|
|
- Affects implementation decisions
|
|
|
|
7. **Rate Limiting**
|
|
- Should rate limiting be per-user or per-IP?
|
|
- Recommendation: Both (user + IP-based)
|
