+# Bitwarden Directory Connector
+
+## Project Overview
+
+Directory Connector is a TypeScript application that synchronizes users and groups from directory services to Bitwarden organizations. It provides both a desktop GUI (built with Angular and Electron) and a CLI tool (bwdc).
+
+**Supported Directory Services:**
+
+- LDAP (Lightweight Directory Access Protocol) - includes Active Directory and general LDAP servers
+- Microsoft Entra ID (formerly Azure Active Directory)
+- Google Workspace
+- Okta
+- OneLogin
+
+**Technologies:**
+
+- TypeScript
+- Angular (GUI)
+- Electron (Desktop wrapper)
+- Node
+- Jest for testing
+
+## Code Architecture & Structure
+
+### Directory Organization
+
+```
+src/
+├── abstractions/       # Interface definitions (e.g., IDirectoryService)
+├── services/          # Business logic implementations for directory services, sync, auth
+├── models/            # Data models (UserEntry, GroupEntry, etc.)
+├── commands/          # CLI command implementations
+├── app/               # Angular GUI components
+└── utils/             # Test utilities and fixtures
+
+src-cli/               # CLI-specific code (imports common code from src/)
+
+jslib/                 # Legacy folder structure (mix of deprecated/unused and current code - new code should not be added here)
+```
+
+### Key Architectural Patterns
+
+1. **Abstractions = Interfaces**: All interfaces are defined in `/abstractions`
+2. **Services = Business Logic**: Implementations live in `/services`
+3. **Directory Service Pattern**: Each directory provider implements `IDirectoryService` interface
+4. **Separation of Concerns**: GUI (Angular app) and CLI (commands) share the same service layer
+
+## Development Conventions
+
+### Code Organization
+
+**File Naming:**
+
+- kebab-case for files: `ldap-directory.service.ts`
+- Descriptive names that reflect purpose
+
+**Class/Function Naming:**
+
+- PascalCase for classes and interfaces
+- camelCase for functions and variables
+- Descriptive names that indicate purpose
+
+**File Structure:**
+
+- Keep files focused on single responsibility
+- Create new service files for distinct directory integrations
+- Separate models into individual files when complex
+
+### TypeScript Conventions
+
+**Import Patterns:**
+
+- Use path aliases (`@/`) for project imports
+  - `@/` - project root
+  - `@/jslib/` - jslib folder
+- ESLint enforces alphabetized import ordering with newlines between groups
+
+**Type Safety:**
+
+- Avoid `any` types - use proper typing or `unknown` with type guards
+- Prefer interfaces for contracts, types for unions/intersections
+- Use strict null checks - handle `null` and `undefined` explicitly
+- Leverage TypeScript's type inference where appropriate
+
+**Configuration:**
+
+- Use configuration files or environment variables
+- Never hardcode URLs or configuration values
+
+## Security Best Practices
+
+**Credential Handling:**
+
+- Never log directory service credentials, API keys, or tokens
+- Use secure storage mechanisms for sensitive data
+- Credentials should never be hardcoded
+- Store credentials encrypted, never in plain text
+
+**Sensitive Data:**
+
+- User and group data from directories should be handled securely
+- Avoid exposing sensitive information in error messages
+- Sanitize data before logging
+- Be cautious with data persistence
+
+**Input Validation:**
+
+- Validate and sanitize data from external directory services
+- Check for injection vulnerabilities (LDAP injection, etc.)
+- Validate configuration inputs from users
+
+**API Security:**
+
+- Ensure authentication flows are implemented correctly
+- Verify SSL/TLS is used for all external connections
+- Check for secure token storage and refresh mechanisms
+
+## Error Handling
+
+**Best Practices:**
+
+1. **Try-catch for async operations** - Always wrap external API calls
+2. **Meaningful error messages** - Provide context for debugging
+3. **Error propagation** - Don't swallow errors silently
+4. **User-facing errors** - Separate user messages from developer logs
+
+## Performance Best Practices
+
+**Large Dataset Handling:**
+
+- Use pagination for large user/group lists
+- Avoid loading entire datasets into memory at once
+- Consider streaming or batch processing for large operations
+
+**API Rate Limiting:**
+
+- Respect rate limits for Microsoft Graph API, Google Admin SDK, etc.
+- Consider batching large API calls where necessary
+
+**Memory Management:**
+
+- Close connections and clean up resources
+- Remove event listeners when components are destroyed
+- Be cautious with caching large datasets
+
+## Testing
+
+**Framework:**
+
+- Jest with jest-preset-angular
+- jest-mock-extended for type-safe mocks with `mock<Type>()`
+
+**Test Organization:**
+
+- Tests colocated with source files
+- `*.spec.ts` - Unit tests for individual components/services
+- `*.integration.spec.ts` - Integration tests against live directory services
+- Test helpers located in `utils/` directory
+
+**Test Naming:**
+
+- Descriptive, human-readable test names
+- Example: `'should return empty array when no users exist in directory'`
+
+**Test Coverage:**
+
+- New features must include tests
+- Bug fixes should include regression tests
+- Changes to core sync logic or directory specific logic require integration tests
+
+**Testing Approach:**
+
+- **Unit tests**: Mock external API calls using jest-mock-extended
+- **Integration tests**: Use live directory services (Docker containers or configured cloud services)
+- Focus on critical paths (authentication, sync, data transformation)
+- Test error scenarios and edge cases (empty results, malformed data, connection failures), not just happy paths
+
+## Directory Service Patterns
+
+### IDirectoryService Interface
+
+All directory services implement this core interface with methods:
+
+- `getUsers()` - Retrieve users from directory and transform them into standard objects
+- `getGroups()` - Retrieve groups from directory and transform them into standard objects
+- Connection and authentication handling
+
+### Service-Specific Implementations
+
+Each directory service has unique authentication and query patterns:
+
+- **LDAP**: Direct LDAP queries, bind authentication
+- **Microsoft Entra ID**: Microsoft Graph API, OAuth tokens
+- **Google Workspace**: Google Admin SDK, service account credentials
+- **Okta/OneLogin**: REST APIs with API tokens
