Requirements Document

Introduction

Migration der Amazon Product Bar Extension von localStorage zu AppWrite Cloud Storage mit benutzerbasierter Authentifizierung. Die Extension soll alle Daten (Enhanced Items, Blacklist, Settings, etc.) in AppWrite speichern und über mehrere Geräte synchronisieren.

Glossary

  • AppWrite: Cloud-Backend-Service für Datenbank, Authentifizierung und Storage
  • Extension: Amazon Product Bar Chrome Extension
  • Enhanced_Item: Erweiterte Produktdaten mit AI-generierten Titeln
  • User_Session: Authentifizierte Benutzersitzung in AppWrite
  • Cloud_Storage: AppWrite Database Collections für Datenpersistierung
  • Migration_Service: Service zur Übertragung von localStorage zu AppWrite

Requirements

Requirement 1: AppWrite Authentication Integration

User Story: Als Benutzer möchte ich mich einmalig anmelden, damit meine Daten sicher in der Cloud gespeichert werden.

Acceptance Criteria

  1. WHEN the extension starts and no user is logged in, THE Extension SHALL display a login interface
  2. WHEN a user provides valid credentials, THE Authentication_Service SHALL authenticate with AppWrite
  3. WHEN authentication succeeds, THE Extension SHALL store the session securely
  4. WHEN authentication fails, THE Extension SHALL display appropriate error messages
  5. WHERE a user is already authenticated, THE Extension SHALL automatically use the existing session

Requirement 2: Cloud Data Storage

User Story: Als Benutzer möchte ich, dass alle meine Extension-Daten in der Cloud gespeichert werden, damit sie geräteübergreifend verfügbar sind.

Acceptance Criteria

  1. WHEN an enhanced item is saved, THE AppWrite_Storage_Manager SHALL store it in the enhanced_items collection
  2. WHEN a brand is blacklisted, THE AppWrite_Storage_Manager SHALL store it in the blacklisted_brands collection
  3. WHEN settings are updated, THE AppWrite_Storage_Manager SHALL store them in the user_settings collection
  4. WHEN migration status changes, THE AppWrite_Storage_Manager SHALL store it in the migration_status collection
  5. THE AppWrite_Storage_Manager SHALL associate all data with the authenticated user ID

Requirement 3: Data Migration from localStorage

User Story: Als bestehender Benutzer möchte ich, dass meine lokalen Daten automatisch in die Cloud migriert werden, damit ich keine Daten verliere.

Acceptance Criteria

  1. WHEN a user logs in for the first time, THE Migration_Service SHALL detect existing localStorage data
  2. WHEN localStorage data exists, THE Migration_Service SHALL migrate all enhanced items to AppWrite
  3. WHEN localStorage data exists, THE Migration_Service SHALL migrate all blacklisted brands to AppWrite
  4. WHEN localStorage data exists, THE Migration_Service SHALL migrate all settings to AppWrite
  5. WHEN migration completes successfully, THE Migration_Service SHALL mark localStorage data as migrated
  6. WHEN migration fails, THE Migration_Service SHALL provide detailed error information and retry options

Requirement 4: Real-time Data Synchronization

User Story: Als Benutzer möchte ich, dass Änderungen sofort auf allen meinen Geräten verfügbar sind, damit ich immer aktuelle Daten habe.

Acceptance Criteria

  1. WHEN data is modified on one device, THE Extension SHALL update the data in AppWrite immediately
  2. WHEN data changes in AppWrite, THE Extension SHALL reflect these changes in the UI
  3. WHEN network connectivity is lost, THE Extension SHALL queue changes for later synchronization
  4. WHEN network connectivity is restored, THE Extension SHALL synchronize all queued changes
  5. WHEN conflicts occur, THE Extension SHALL use the most recent timestamp to resolve them

Requirement 5: Offline Capability with Sync

User Story: Als Benutzer möchte ich die Extension auch offline nutzen können, damit ich auch ohne Internetverbindung arbeiten kann.

Acceptance Criteria

  1. WHEN the extension is offline, THE Extension SHALL continue to function with cached data
  2. WHEN offline changes are made, THE Extension SHALL store them locally for later sync
  3. WHEN connectivity is restored, THE Extension SHALL automatically sync offline changes to AppWrite
  4. WHEN sync conflicts occur, THE Extension SHALL prioritize the most recent changes
  5. THE Extension SHALL provide visual indicators for offline status and sync progress

Requirement 6: Error Handling and Fallback

User Story: Als Benutzer möchte ich, dass die Extension auch bei Cloud-Problemen weiterhin funktioniert, damit meine Arbeit nicht unterbrochen wird.

Acceptance Criteria

  1. WHEN AppWrite is unavailable, THE Extension SHALL fall back to localStorage temporarily
  2. WHEN authentication expires, THE Extension SHALL prompt for re-authentication
  3. WHEN API rate limits are exceeded, THE Extension SHALL implement exponential backoff
  4. WHEN data corruption is detected, THE Extension SHALL attempt automatic recovery
  5. WHEN critical errors occur, THE Extension SHALL provide user-friendly error messages in German

Requirement 7: Security and Privacy

User Story: Als Benutzer möchte ich, dass meine Daten sicher gespeichert und nur für mich zugänglich sind, damit meine Privatsphäre geschützt ist.

Acceptance Criteria

  1. THE Extension SHALL only access data belonging to the authenticated user
  2. THE Extension SHALL encrypt sensitive data like API keys before storing in AppWrite
  3. THE Extension SHALL use secure HTTPS connections for all AppWrite communication
  4. THE Extension SHALL automatically log out users after extended inactivity
  5. THE Extension SHALL never store authentication credentials in localStorage

Requirement 8: Performance Optimization

User Story: Als Benutzer möchte ich, dass die Extension trotz Cloud-Integration schnell und responsiv bleibt, damit meine Produktivität nicht beeinträchtigt wird.

Acceptance Criteria

  1. WHEN loading data, THE Extension SHALL implement intelligent caching strategies
  2. WHEN syncing large datasets, THE Extension SHALL use batch operations to minimize API calls
  3. WHEN displaying lists, THE Extension SHALL implement pagination for large collections
  4. WHEN network is slow, THE Extension SHALL prioritize critical operations
  5. THE Extension SHALL preload frequently accessed data to improve response times
