Aniworld Web Application Development Instructions

This document provides detailed tasks for AI agents to implement a modern web application for the Aniworld anime download manager. All tasks should follow the coding guidelines specified in the project's copilot instructions.

Project Overview

The goal is to create a FastAPI-based web application that provides a modern interface for the existing Aniworld anime download functionality. The core anime logic should remain in SeriesApp.py while the web layer provides REST API endpoints and a responsive UI.

Architecture Principles

• Single Responsibility: Each file/class has one clear purpose
• Dependency Injection: Use FastAPI's dependency system
• Clean Separation: Web layer calls core logic, never the reverse
• File Size Limit: Maximum 500 lines per file
• Type Hints: Use comprehensive type annotations
• Error Handling: Proper exception handling and logging

Additional Implementation Guidelines

Code Style and Standards

• Type Hints: Use comprehensive type annotations throughout all modules
• Docstrings: Follow PEP 257 for function and class documentation
• Error Handling: Implement custom exception classes with meaningful messages
• Logging: Use structured logging with appropriate log levels
• Security: Validate all inputs and sanitize outputs
• Performance: Use async/await patterns for I/O operations

📞 Escalation

If you encounter:

• Architecture issues requiring design decisions
• Tests that conflict with documented requirements
• Breaking changes needed
• Unclear requirements or expectations

Document the issue and escalate rather than guessing.

Implementation Notes

1. Incremental Development: Implement features incrementally, testing each component thoroughly before moving to the next
2. Code Review: Review all generated code for adherence to project standards
3. Documentation: Document all public APIs and complex logic
4. Testing: Maintain test coverage above 80% for all new code
5. Performance: Profile and optimize critical paths, especially download and streaming operations
6. Security: Regular security audits and dependency updates
7. Monitoring: Implement comprehensive monitoring and alerting
8. Maintenance: Plan for regular maintenance and updates

TODO List:

✅ FIXED: Anime list endpoint now correctly returns anime data after server startup.

Root Cause: The anime list was empty because:

1. The SeriesApp.list was initialized with skip_load=True to avoid loading from filesystem during initialization
2. Series data is synced from filesystem data files to the database during server startup
3. Series are then loaded from the database into SeriesApp memory via anime_service._load_series_from_db()
4. The server needed to be restarted to complete this initialization process

Solution: The existing startup process in fastapi_app.py correctly:

• Syncs series from data files to database via sync_series_from_data_files()
• Loads series from database into memory via anime_service._load_series_from_db()

The issue was resolved by restarting the server to allow the full initialization process to complete.

Verified: GET /api/anime now returns 192 anime series with complete metadata including:

• Unique key (primary identifier)
• Name and folder
• Missing episodes tracking
• NFO metadata status
• TMDB/TVDB IDs when available
