- Integrated BetterAuth library for modern authentication - Added Session, Account, and Verification database tables - Created complete auth module with service, controller, guards, and decorators - Implemented shared authentication types in @mosaic/shared package - Added comprehensive test coverage (26 tests passing) - Documented type sharing strategy for monorepo - Updated environment configuration with OIDC and JWT settings Key architectural decisions: - BetterAuth over Passport.js for better TypeScript support - Separation of User (DB entity) vs AuthUser (client-safe subset) - Shared types package to prevent FE/BE drift - Factory pattern for auth config to use shared Prisma instance Ready for frontend integration (Issue #6).

# Issue #4: Authentik OIDC integration
|
|
|
|
## Objective
|
|
Implement Authentik OIDC (OpenID Connect) authentication integration for the Mosaic Stack API. This will enable secure user authentication via the Authentik identity provider, supporting multi-tenant workspaces.
|
|
|
|
## Approach
|
|
1. Install BetterAuth library and dependencies
|
|
2. Configure BetterAuth with Authentik OIDC provider
|
|
3. Create auth module using BetterAuth
|
|
4. Add authentication middleware and guards
|
|
5. Configure environment variables for Authentik
|
|
6. Create user management service integrated with BetterAuth
|
|
7. Write comprehensive tests (TDD approach)
|
|
|
|
## BetterAuth Configuration
|
|
- Use BetterAuth's built-in OIDC support for Authentik
|
|
- Leverage BetterAuth's session management
|
|
- Integrate with Prisma ORM for user storage
|
|
|
|
## Progress
|
|
- [x] Create scratchpad
|
|
- [x] Explore existing codebase
|
|
- [x] Install BetterAuth dependencies
|
|
- [x] Implement BetterAuth configuration
|
|
- [x] Create auth guards and decorators
|
|
- [x] Add auth service
|
|
- [x] Configure environment
|
|
- [x] Write tests (26 tests passing)
|
|
- [x] Build and verify
|
|
- [x] Code review (all critical issues fixed)
|
|
- [x] QA testing (identified improvements for future)
|
|
- [x] Fix code review issues
|
|
|
|
## Testing
|
|
- Unit tests for auth service and strategy
|
|
- Integration tests for OIDC flow
|
|
- E2E tests for protected endpoints
|
|
- Target: 85% coverage minimum
|
|
|
|
## Implementation Summary
|
|
|
|
### Completed
|
|
1. **BetterAuth Integration**: Implemented using BetterAuth library for modern, type-safe authentication
|
|
2. **Database Schema**: Added Session, Account, and Verification tables for BetterAuth
|
|
3. **Auth Module**: Created complete NestJS auth module with service, controller, guards, and decorators
|
|
4. **Shared Prisma Client**: Fixed duplicate PrismaClient issue by using shared instance
|
|
5. **Type Safety**: Added proper TypeScript types for AuthUser interface
|
|
6. **Error Handling**: Sanitized error logging to prevent sensitive data exposure
|
|
7. **Test Coverage**: 26 tests passing covering service, controller, and guards
|
|
8. **Code Review**: All critical issues from code review have been addressed
|
