v0.4.0
SaaSKit v0.4.0
This release introduces Extensible Identity Metadata, allowing applications to attach custom structured data to users and organizations without requiring database schema changes.
This completes Phase 4 of the SaaSKit roadmap and significantly improves the platform's flexibility for real-world SaaS applications.
🚀 Highlights
Extensible User Metadata
Users now support two metadata stores:
- Public metadata
- Private metadata
This enables applications to safely separate client-visible information from backend-only data while maintaining a consistent identity model.
Typical use cases include:
- Profile preferences
- Application settings
- Feature flags
- CRM identifiers
- Synchronization state
- Internal service data
Tenant Metadata
Organizations can now store arbitrary JSON metadata, making it easy to support application-specific configuration without modifying the database schema.
Examples include:
- Branding
- Billing settings
- External system IDs
- Marketplace configuration
- Business preferences
- Custom integrations
🔒 RBAC Integration
Metadata operations are fully integrated into SaaSKit's permission system.
New permissions:
user.metadata.readuser.metadata.writetenant.metadata.readtenant.metadata.write
⚡ PostgreSQL JSONB
Metadata is powered by PostgreSQL JSONB with:
- GIN indexes
- 32 KB size limits
- Efficient querying
- Flexible document storage
📡 Event Driven
Metadata updates now publish system events:
user.metadata.updatedtenant.metadata.updated
These events provide the foundation for audit logging, integrations, background workers, and future webhook support.
🌐 New API Endpoints
Users
GET /api/v1/users/me/metadata
PATCH /api/v1/users/me/metadata
Tenants
GET /api/v1/tenants/{id}/metadata
PATCH /api/v1/tenants/{id}/metadata
🧪 Testing
This release adds comprehensive integration tests covering:
- User metadata
- Tenant metadata
- RBAC authorization
- Repository implementations
All tests are passing.
