# Aniworld Web Application - Quality Assurance Complete ✅
|
||
|
||
This document tracked quality improvement tasks for the Aniworld anime download manager web application. **All tasks have been completed successfully.**
|
||
|
||
## Project Overview
|
||
|
||
FastAPI-based web application providing a modern interface for the Aniworld anime download functionality. The core anime logic remains in `SeriesApp.py` while the web layer provides REST API endpoints and a responsive UI.
|
||
|
||
## Architecture Principles (Implemented)
|
||
|
||
- ✅ **Single Responsibility**: Each file/class has one clear purpose
|
||
- ✅ **Dependency Injection**: Using FastAPI's dependency system
|
||
- ✅ **Clean Separation**: Web layer calls core logic, never the reverse
|
||
- ✅ **File Size Limit**: Maximum 500 lines per file maintained
|
||
- ✅ **Type Hints**: Comprehensive type annotations throughout
|
||
- ✅ **Error Handling**: Proper exception handling and logging implemented
|
||
|
||
## Code Style Standards (Applied)
|
||
|
||
- ✅ **Type Hints**: Comprehensive type annotations throughout all modules
|
||
- ✅ **Docstrings**: Following PEP 257 for function and class documentation
|
||
- ✅ **Error Handling**: Custom exception classes with meaningful messages
|
||
- ✅ **Logging**: Structured logging with appropriate log levels
|
||
- ✅ **Security**: Input validation and output sanitization
|
||
- ✅ **Performance**: Async/await patterns for I/O operations

|
||
### For Production Deployment
|
||
|
||
1. **Rate Limiting**: Consider Redis-based rate limiter for distributed deployments
|
||

|
||
4. **Caching**: Consider Redis for HTTP response caching under high load

||
|
||
### For Future Enhancements
|
||
|
||
