## Series Identifier Convention
### Understanding Series Identifiers
The application uses two identifiers for anime series:
| Identifier | Purpose | Example | Used For |
| ---------- | ------------------------ | -------------------------- | ---------------- |
| `key` | **Primary identifier** | `"attack-on-titan"` | All API lookups |
| `folder` | Filesystem metadata only | `"Attack on Titan (2013)"` | Display purposes |
### Key Format
- Lowercase letters and numbers only
- Words separated by hyphens (`-`)
- No spaces, underscores, or uppercase letters
- Examples: `"one-piece"`, `"86-eighty-six"`, `"re-zero"`
### Usage Guidelines
```python
# ✅ Correct: Use 'key' for API operations
GET /api/anime/attack-on-titan
POST /api/queue/add {"serie_id": "attack-on-titan", ...}
# ❌ Deprecated: Folder-based lookups (backward compatibility only)
GET /api/anime/Attack%20on%20Titan%20(2013) # Will work but deprecated
```
### Backward Compatibility
For existing integrations, folder-based lookups are still supported but deprecated:
- API endpoints check `key` first, then fall back to `folder`
- New code should always use `key` as the identifier
- Deprecation warnings will be added in future versions
## Documentation Examples
### API Usage Example
```bash
# Setup
curl -X POST http://localhost:8000/api/auth/setup \
-H "Content-Type: application/json" \
-d '{"master_password": "secure_pass"}'
# Login
TOKEN=$(curl -X POST http://localhost:8000/api/auth/login \
-H "Content-Type: application/json" \
-d '{"password": "secure_pass"}' | jq -r '.token')
# List anime
curl http://localhost:8000/api/v1/anime \
-H "Authorization: Bearer $TOKEN"
```
### Deployment Example
```bash
# Clone and setup
git clone https://github.com/your-repo/aniworld.git
cd aniworld
python3.10 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
# Run application
python -m uvicorn src.server.fastapi_app:app --host 127.0.0.1 --port 8000

# Location: data/aniworld.db
```
### PostgreSQL (Production)
**Install PostgreSQL**:
```bash
sudo apt-get install postgresql postgresql-contrib
```
**Create Database**:
```bash
sudo su - postgres
createdb aniworld
createuser aniworld_user
psql -c "ALTER USER aniworld_user WITH PASSWORD 'password';"
psql -c "GRANT ALL PRIVILEGES ON DATABASE aniworld TO aniworld_user;"
exit
```
**Update Connection String**:
```bash
DATABASE_URL=postgresql://aniworld_user:password@localhost:5432/aniworld
```
**Run Migrations** (if applicable):
```bash
alembic upgrade head
```
## Security Considerations
### Access Control
1. **Master Password**: Use strong, complex password
2. **User Permissions**: Run app with minimal required permissions
3. **Firewall**: Restrict access to necessary ports only
4. **SSL/TLS**: Always use HTTPS in production
### Data Protection
1. **Encryption**: Encrypt JWT secrets and sensitive data
2. **Backups**: Regular automated backups
3. **Audit Logging**: Enable comprehensive logging
4. **Database**: Use PostgreSQL for better security than SQLite
### Network Security
1. **HTTPS**: Use SSL/TLS certificates
2. **CORS**: Configure appropriate CORS origins
3. **Rate Limiting**: Enable rate limiting on all endpoints
4. **WAF**: Consider Web Application Firewall
### Secrets Management
1. **Environment Variables**: Use .env for secrets
2. **Secret Store**: Use tools like HashiCorp Vault
3. **Rotation**: Regularly rotate JWT secrets
4. **Audit**: Monitor access to sensitive data
## Monitoring & Maintenance
### Health Checks
**Basic Health**:
```bash
curl http://localhost:8000/health
```
**Detailed Health**:
```bash
curl http://localhost:8000/health/detailed
```
### Logging
**View Logs**:
```bash
# Systemd
sudo journalctl -u aniworld -f
# Docker
docker logs -f aniworld
# Log file
tail -f logs/app.log
```
### Maintenance Tasks
**Daily**:
- Check disk space
- Monitor error logs
- Verify downloads completing
**Weekly**:

# PostgreSQL cleanup
psql -d aniworld -c "VACUUM ANALYZE;"
# SQLite cleanup
sqlite3 data/aniworld.db "VACUUM;"
```
## Troubleshooting
### Application Won't Start
**Check Logs**:
```bash
sudo journalctl -u aniworld -n 50
```
**Common Issues**:
- Port already in use: Change port or kill process
- Database connection: Verify DATABASE_URL
- File permissions: Check directory ownership
### High Memory Usage
**Solutions**:
- Reduce worker processes
- Check for memory leaks in logs
- Restart application periodically
- Monitor with `htop` or `top`
### Slow Performance
**Optimization**:
- Use PostgreSQL instead of SQLite
- Increase worker processes
- Add more RAM
- Optimize database queries
- Cache static files with CDN
### Downloads Failing
**Check**:
- Internet connection
- Anime provider availability
- Disk space on download directory
- File permissions
**Debug**:
```bash
curl -v http://provider-url/stream
```
### SSL/TLS Issues
**Certificate Problems**:
```bash
sudo certbot renew --dry-run

**Status**: ✅ Complete and well-structured
---
## Middleware Error Handling
### Global Exception Handlers
**Location**: `src/server/middleware/error_handler.py`
The application registers global exception handlers for all custom exception classes:
```python
def register_exception_handlers(app: FastAPI) -> None:
"""Register all exception handlers with FastAPI app."""
@app.exception_handler(AuthenticationError)
async def authentication_error_handler(
request: Request, exc: AuthenticationError
) -> JSONResponse:
"""Handle authentication errors (401)."""
logger.warning(
f"Authentication error: {exc.message}",
extra={"details": exc.details, "path": str(request.url.path)},
)
return JSONResponse(
status_code=exc.status_code,
content=create_error_response(
status_code=exc.status_code,
error=exc.error_code,
message=exc.message,
details=exc.details,
request_id=getattr(request.state, "request_id", None),
),
)
# ... similar handlers for all exception types
```
### Error Response Format
All errors return a consistent JSON structure:
```json
{
"success": false,
"error": "ERROR_CODE",
"message": "Human-readable error message",
"details": {
"field": "specific_field",
"reason": "error_reason"
},
"request_id": "uuid-request-identifier"
}
```
**Status**: ✅ Comprehensive and consistent
---
## API Endpoint Error Handling
### Authentication Endpoints (`/api/auth`)
**File**: `src/server/api/auth.py`
#### ✅ Error Handling Strengths
- **Setup endpoint**: Checks if master password already configured
- **Login endpoint**: Handles lockout errors (429) and authentication failures (401)
- **Proper exception mapping**: `LockedOutError` → 429, `AuthError` → 400
- **Token validation**: Graceful handling of invalid tokens
```python
@router.post("/login", response_model=LoginResponse)
def login(req: LoginRequest):
"""Validate master password and return JWT token."""
identifier = "global"
try:
valid = auth_service.validate_master_password(
req.password, identifier=identifier
)
except LockedOutError as e:
raise HTTPException(
status_code=http_status.HTTP_429_TOO_MANY_REQUESTS,
detail=str(e),
) from e
except AuthError as e:
raise HTTPException(status_code=400, detail=str(e)) from e
if not valid:
raise HTTPException(status_code=401, detail="Invalid credentials")
```
#### Recommendations
- ✓ Add structured logging for failed login attempts
- ✓ Include request_id in error responses
- ✓ Consider adding more detailed error messages for debugging

- **Generic 500 errors** for unexpected failures
- **Input validation** with Pydantic models and custom validators
```python
@router.get("/", response_model=List[AnimeSummary])
async def list_anime(
_auth: dict = Depends(require_auth),
series_app: Any = Depends(get_series_app),
) -> List[AnimeSummary]:
"""List library series that still have missing episodes."""
try:
series = series_app.List.GetMissingEpisode()
summaries: List[AnimeSummary] = []
# ... processing logic
return summaries
except HTTPException:
raise # Preserve status code
except Exception as exc:
raise HTTPException(
status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
detail="Failed to retrieve anime list",
) from exc
```
#### ✅ Advanced Input Validation
The search endpoint includes comprehensive input validation:
```python
class SearchRequest(BaseModel):
"""Request model for anime search with validation."""
query: str
@field_validator("query")
@classmethod
def validate_query(cls, v: str) -> str:
"""Validate and sanitize search query."""
if not v or not v.strip():
raise ValueError("Search query cannot be empty")
# Limit query length to prevent abuse
if len(v) > 200:
raise ValueError("Search query too long (max 200 characters)")
# Strip and normalize whitespace
normalized = " ".join(v.strip().split())
# Prevent SQL-like injection patterns
dangerous_patterns = [
"--", "/*", "*/", "xp_", "sp_", "exec", "execute"
]
lower_query = normalized.lower()
for pattern in dangerous_patterns:
if pattern in lower_query:
raise ValueError(f"Invalid character sequence: {pattern}")
return normalized
```

@router.put("", response_model=AppConfig)
def update_config(
update: ConfigUpdate, auth: dict = Depends(require_auth)
) -> AppConfig:
"""Apply an update to the configuration and persist it."""
try:
config_service = get_config_service()
return config_service.update_config(update)
except ConfigValidationError as e:
raise HTTPException(
status_code=status.HTTP_400_BAD_REQUEST,
detail=f"Invalid configuration: {e}"
) from e
except ConfigServiceError as e:
raise HTTPException(
status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
detail=f"Failed to update config: {e}"
) from e
```
**Status**: ✅ Excellent separation of validation and service errors
---
### Health Check Endpoints (`/health`)
**File**: `src/server/api/health.py`
#### ✅ Error Handling Strengths
- **Graceful degradation** - returns partial health status even if some checks fail
- **Detailed error logging** for diagnostic purposes
- **Structured health responses** with status indicators
- **No exceptions thrown to client** - health checks always return 200
```python
async def check_database_health(db: AsyncSession) -> DatabaseHealth:
"""Check database connection and performance."""
try:
import time
start_time = time.time()
await db.execute(text("SELECT 1"))
connection_time = (time.time() - start_time) * 1000
return DatabaseHealth(
status="healthy",
connection_time_ms=connection_time,
message="Database connection successful",
)
except Exception as e:
logger.error(f"Database health check failed: {e}")
return DatabaseHealth(
status="unhealthy",
connection_time_ms=0,
message=f"Database connection failed: {str(e)}",
)
```

```python
@router.websocket("/connect")
async def websocket_endpoint(
websocket: WebSocket,
ws_service: WebSocketService = Depends(get_websocket_service),
user_id: Optional[str] = Depends(get_current_user_optional),
):
"""WebSocket endpoint for client connections."""
connection_id = str(uuid.uuid4())
try:
await ws_service.connect(websocket, connection_id, user_id=user_id)
# ... connection handling
while True:
try:
data = await websocket.receive_json()
try:
client_msg = ClientMessage(**data)
except Exception as e:
logger.warning(
"Invalid client message format",
connection_id=connection_id,
error=str(e),
)
await ws_service.send_error(
connection_id,
"Invalid message format",
"INVALID_MESSAGE",
)
continue

---
### Analytics Endpoints (`/api/analytics`)
**File**: `src/server/api/analytics.py`
#### ⚠️ Error Handling Observations
- ✅ Pydantic models for response validation
- ⚠️ **Missing explicit error handling** in some endpoints
- ⚠️ Database session handling could be improved
#### Recommendation
Add try-catch blocks to all analytics endpoints:
```python
@router.get("/downloads", response_model=DownloadStatsResponse)
async def get_download_statistics(
days: int = 30,
db: AsyncSession = None,
) -> DownloadStatsResponse:
"""Get download statistics for specified period."""
try:
if db is None:
db = await get_db().__anext__()
service = get_analytics_service()
stats = await service.get_download_stats(db, days=days)
return DownloadStatsResponse(
total_downloads=stats.total_downloads,
successful_downloads=stats.successful_downloads,
# ... rest of response
)
except Exception as e:
logger.error(f"Failed to get download statistics: {e}")
raise HTTPException(
status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
detail=f"Failed to retrieve download statistics: {str(e)}",
) from e
```
**Status**: ⚠️ Needs enhancement
---
### Backup Endpoints (`/api/backup`)
**File**: `src/server/api/backup.py`
#### ✅ Error Handling Strengths
- **Custom exception handling** in create_backup endpoint
- **ValueError handling** for invalid backup types
- **Comprehensive logging** for all operations
#### ⚠️ Observations
Some endpoints may not have explicit error handling:
```python
@router.post("/create", response_model=BackupResponse)
async def create_backup(
request: BackupCreateRequest,
backup_service: BackupService = Depends(get_backup_service_dep),
) -> BackupResponse:
"""Create a new backup."""
try:
backup_info = None
if request.backup_type == "config":
backup_info = backup_service.backup_configuration(
request.description or ""
)
elif request.backup_type == "database":
backup_info = backup_service.backup_database(
request.description or ""
)
elif request.backup_type == "full":
backup_info = backup_service.backup_full(
request.description or ""
)
else:
raise ValueError(f"Invalid backup type: {request.backup_type}")
# ... rest of logic
except ValueError as e:
raise HTTPException(
status_code=status.HTTP_400_BAD_REQUEST,
detail=str(e),
) from e
except Exception as e:
logger.error(f"Backup creation failed: {e}")
raise HTTPException(
status_code=status.HTTP_500_INTERNAL_SERVER_ERROR,
detail=f"Failed to create backup: {str(e)}",
) from e
```
**Status**: ✅ Good error handling with minor improvements possible
---
### Maintenance Endpoints (`/api/maintenance`)
**File**: `src/server/api/maintenance.py`
#### ✅ Error Handling Strengths
- **Comprehensive try-catch blocks** in all endpoints
- **Detailed error logging** for troubleshooting
- **Proper HTTP status codes** (500 for failures)
- **Graceful degradation** where possible
```python
@router.post("/cleanup")
async def cleanup_temporary_files(
max_age_days: int = 30,
system_utils=Depends(get_system_utils),
) -> Dict[str, Any]:
"""Clean up temporary and old files."""
try:
deleted_logs = system_utils.cleanup_directory(
"logs", "*.log", max_age_days
)
deleted_temp = system_utils.cleanup_directory(
"Temp", "*", max_age_days
)
deleted_dirs = system_utils.cleanup_empty_directories("logs")
return {
"success": True,
"deleted_logs": deleted_logs,
"deleted_temp_files": deleted_temp,
"deleted_empty_dirs": deleted_dirs,
"total_deleted": deleted_logs + deleted_temp + deleted_dirs,
}
except Exception as e:
logger.error(f"Cleanup failed: {e}")
raise HTTPException(status_code=500, detail=str(e))
```
**Status**: ✅ Excellent error handling
---
## Response Format Consistency
### Current Response Formats
The API uses **multiple response formats** depending on the endpoint:
#### Format 1: Success/Data Pattern (Most Common)
```json
{
"success": true,
"data": { ... },
"message": "Optional message"
}
```
#### Format 2: Status/Message Pattern
```json
{
"status": "ok",
"message": "Operation completed"
}
```
#### Format 3: Direct Data Return
```json
{
"field1": "value1",
"field2": "value2"
}
```
#### Format 4: Error Response (Standardized)
```json
{
"success": false,
"error": "ERROR_CODE",
"message": "Human-readable message",
"details": { ... },
"request_id": "uuid"
}
```
### ⚠️ Consistency Recommendation
While error responses are highly consistent (Format 4), **success responses vary** between formats 1, 2, and 3.
#### Recommended Standard Format
```json
// Success
{
"success": true,
"data": { ... },
"message": "Optional success message"
}
// Error
{
"success": false,
"error": "ERROR_CODE",
"message": "Error description",
"details": { ... },
"request_id": "uuid"
}
```
**Action Item**: Consider standardizing all success responses to Format 1 for consistency with error responses.
---
## Logging Standards
### Current Logging Implementation
#### ✅ Strengths
1. **Structured logging** with `structlog` in WebSocket module
2. **Appropriate log levels**: INFO, WARNING, ERROR
3. **Contextual information** in log messages
4. **Extra fields** for better filtering
#### ⚠️ Areas for Improvement
1. **Inconsistent logging libraries**: Some modules use `logging`, others use `structlog`
2. **Missing request IDs** in some log messages
3. **Incomplete correlation** between logs and errors
### Recommended Logging Pattern
```python
import structlog
logger = structlog.get_logger(__name__)
@router.post("/endpoint")
async def endpoint(request: Request, data: RequestModel):
request_id = str(uuid.uuid4())
request.state.request_id = request_id
logger.info(
"Processing request",
request_id=request_id,
endpoint="/endpoint",
method="POST",
user_id=getattr(request.state, "user_id", None),
)
try:
# ... processing logic
logger.info(
"Request completed successfully",
request_id=request_id,
duration_ms=elapsed_time,
)
return {"success": True, "data": result}
except Exception as e:
logger.error(
"Request failed",
request_id=request_id,
error=str(e),
error_type=type(e).__name__,
exc_info=True,
)
raise
```

# Frontend-Backend Integration Summary
**Date:** October 24, 2025
**Status:** Core integration completed
## Overview
Successfully integrated the existing frontend JavaScript application with the new FastAPI backend by creating missing API endpoints and updating frontend API calls to match the new endpoint structure.
## Completed Work
### 1. Created Missing API Endpoints
Added the following endpoints to `/src/server/api/anime.py`:
#### `/api/v1/anime/status` (GET)
- Returns anime library status information
- Response includes:
- `directory`: Configured anime directory path
- `series_count`: Number of series in the library
- Used by frontend configuration modal to display current settings
#### `/api/v1/anime/add` (POST)
- Adds a new series to the library from search results
- Request body: `{link: string, name: string}`
- Validates input and calls `SeriesApp.AddSeries()` method
- Returns success/error message
#### `/api/v1/anime/download` (POST)
- Starts downloading missing episodes from selected folders
- Request body: `{folders: string[]}`
- Calls `SeriesApp.Download()` with folder list
- Used when user selects multiple series and clicks download
### 2. Updated Frontend API Calls
Modified `/src/server/web/static/js/app.js` to use correct endpoint paths:
| Old Path | New Path | Purpose |
| ----------------- | ------------------------ | ------------------------- |
| `/api/add_series` | `/api/v1/anime/add` | Add new series |
| `/api/download` | `/api/v1/anime/download` | Download selected folders |
| `/api/status` | `/api/v1/anime/status` | Get library status |
### 3. Verified Existing Endpoints
Confirmed the following endpoints are already correctly implemented:
- `/api/auth/status` - Authentication status check
- `/api/auth/logout` - User logout
- `/api/v1/anime` - List anime with missing episodes
- `/api/v1/anime/search` - Search for anime
- `/api/v1/anime/rescan` - Trigger library rescan
- `/api/v1/anime/{anime_id}` - Get anime details
- `/api/queue/*` - Download queue management
- `/api/config/*` - Configuration management
## Request/Response Models
### AddSeriesRequest
```python
class AddSeriesRequest(BaseModel):
link: str # Series URL/link
name: str # Series name
```
### DownloadFoldersRequest
```python
class DownloadFoldersRequest(BaseModel):
folders: List[str] # List of folder names to download
```
## Testing
- All existing tests passing
- Integration tested with frontend JavaScript
- Endpoints follow existing patterns and conventions
- Proper error handling and validation in place
## Remaining Work
The following endpoints are referenced in the frontend but not yet implemented:
### Scheduler API (`/api/scheduler/`)
- `/api/scheduler/config` (GET/POST) - Get/update scheduler configuration
- `/api/scheduler/trigger-rescan` (POST) - Manually trigger scheduled rescan
### Logging API (`/api/logging/`)
- `/api/logging/config` (GET/POST) - Get/update logging configuration
- `/api/logging/files` (GET) - List log files
- `/api/logging/files/{filename}/download` (GET) - Download log file
- `/api/logging/files/{filename}/tail` (GET) - Tail log file
- `/api/logging/test` (POST) - Test logging configuration
- `/api/logging/cleanup` (POST) - Clean up old log files
### Diagnostics API (`/api/diagnostics/`)
- `/api/diagnostics/network` (GET) - Network diagnostics
### Config API Extensions
The following config endpoints may need verification or implementation:
- `/api/config/section/advanced` (GET/POST) - Advanced configuration section
- `/api/config/directory` (POST) - Update anime directory
- `/api/config/backup` (POST) - Create configuration backup
- `/api/config/backups` (GET) - List configuration backups
- `/api/config/backup/{name}/restore` (POST) - Restore backup
- `/api/config/backup/{name}/download` (GET) - Download backup
- `/api/config/export` (POST) - Export configuration
- `/api/config/validate` (POST) - Validate configuration
- `/api/config/reset` (POST) - Reset configuration to defaults
## Architecture Notes
### Endpoint Organization
- Anime-related endpoints: `/api/v1/anime/`
- Queue management: `/api/queue/`
- Configuration: `/api/config/`
- Authentication: `/api/auth/`
- Health checks: `/health`
### Design Patterns Used
- Dependency injection for `SeriesApp` instance
- Request validation with Pydantic models
- Consistent error handling and HTTP status codes
- Authentication requirements on all endpoints
- Proper async/await patterns
### Frontend Integration
- Frontend uses `makeAuthenticatedRequest()` helper for API calls
- Bearer token authentication in Authorization header
- Consistent response format expected: `{status: string, message: string, ...}`
- WebSocket integration preserved for real-time updates
## Security Considerations
- All endpoints require authentication via `require_auth` dependency
- Input validation on request models (link length, folder list)
- Proper error messages without exposing internal details
- No injection vulnerabilities in search/add operations
## Future Improvements
1. **Implement missing APIs**: Scheduler, Logging, Diagnostics
2. **Enhanced validation**: Add more comprehensive input validation
3. **Rate limiting**: Add per-endpoint rate limiting if needed
4. **Caching**: Consider caching for status endpoints
5. **Pagination**: Add pagination to anime list endpoint
6. **Filtering**: Add filtering options to anime list
7. **Batch operations**: Support batch add/download operations
8. **Progress tracking**: Enhance real-time progress updates
## Files Modified
- `src/server/api/anime.py` - Added 4 new endpoints
- `src/server/web/static/js/app.js` - Updated 4 API call paths
- `instructions.md` - Marked frontend integration tasks as completed
## Conclusion
The core frontend-backend integration is now complete. The main user workflows (listing anime, searching, adding series, downloading) are fully functional. The remaining work involves implementing administrative and configuration features (scheduler, logging, diagnostics) that enhance the application but are not critical for basic operation.
All tests are passing, and the integration follows established patterns and best practices for the project.

## API Integration
### Current API Endpoints Used
#### Authentication Endpoints
```javascript
// Check authentication status
GET /api/auth/status
Headers: { Authorization: Bearer <token> }
// Login
POST /api/auth/login
Body: { password: string }
Response: { token: string, token_type: string }
// Logout
POST /api/auth/logout
```
#### Anime Endpoints
```javascript
// List all anime
GET /api/v1/anime
Response: { success: bool, data: Array<Anime> }
// Search anime
GET /api/v1/anime/search?query=<search_term>
Response: { success: bool, data: Array<Anime> }
// Get anime details
GET /api/v1/anime/{anime_id}
Response: { success: bool, data: Anime }
```
#### Download Queue Endpoints
```javascript
// Get queue status
GET /api/v1/download/queue
Response: { queue: Array<DownloadItem>, is_running: bool }
// Add to queue
POST /api/v1/download/queue
Body: { anime_id: string, episodes: Array<number> }
// Start queue
POST /api/v1/download/queue/start
// Stop queue
POST /api/v1/download/queue/stop
// Pause queue
POST /api/v1/download/queue/pause
// Resume queue
POST /api/v1/download/queue/resume
// Reorder queue
PUT /api/v1/download/queue/reorder
Body: { queue_order: Array<string> }
// Remove from queue
DELETE /api/v1/download/queue/{item_id}
```
#### Configuration Endpoints
```javascript
// Get configuration
GET / api / v1 / config;
Response: {
config: ConfigObject;
}
// Update configuration
PUT / api / v1 / config;
Body: ConfigObject;
```
### API Call Pattern
All API calls follow this pattern in the JavaScript files:
```javascript
async function apiCall(endpoint, options = {}) {
try {
const token = localStorage.getItem("access_token");
const headers = {
"Content-Type": "application/json",
...(token && { Authorization: `Bearer ${token}` }),
...options.headers,
};
const response = await fetch(endpoint, {
...options,
headers,
});
if (!response.ok) {
if (response.status === 401) {
// Redirect to login
window.location.href = "/login";
return;
}
throw new Error(`HTTP ${response.status}: ${response.statusText}`);
}
return await response.json();
} catch (error) {
console.error("API call failed:", error);
throw error;
}
}
```
### Required API Updates
The following API endpoints need to be verified/updated to match frontend expectations:
1. **Response Format Consistency**
- All responses should include `success` boolean
- Error responses should include `error`, `message`, and `details`
- Success responses should include `data` field
2. **Authentication Flow**
- `/api/auth/status` endpoint for checking authentication
- Proper 401 responses for unauthenticated requests
- Token refresh mechanism (if needed)
3. **Queue Operations**
- Ensure queue reordering endpoint exists
- Validate pause/resume functionality
- Check queue status polling endpoint
## WebSocket Integration
### WebSocket Connection
The frontend uses a custom WebSocket client (`websocket_client.js`) that provides a Socket.IO-like interface over native WebSocket.
#### Connection Endpoint
```javascript
const protocol = window.location.protocol === "https:" ? "wss:" : "ws:";
const host = window.location.host;
const wsUrl = `${protocol}//${host}/ws/connect`;
```
### WebSocket Events
#### Events Sent by Frontend
```javascript
// Join a room (for targeted updates)
socket.emit("join", { room: "downloads" });
socket.emit("join", { room: "download_progress" });
// Leave a room
socket.emit("leave", { room: "downloads" });
// Custom events (as needed)
socket.emit("custom_event", { data: "value" });
```
#### Events Received by Frontend
##### Connection Events
```javascript
socket.on("connect", () => {
// Connection established
});
socket.on("disconnect", (data) => {
// Connection lost - data: { code, reason }
});
socket.on("connected", (data) => {
// Server confirmation - data: { message, timestamp }
});
```
##### Queue Events
```javascript
// Queue status updates
socket.on("queue_status", (data) => {
// data: { queue_status: { queue: [], is_running: bool } }
});
socket.on("queue_updated", (data) => {
// Legacy event - same as queue_status
});
// Download lifecycle
socket.on("queue_started", () => {
// Queue processing started
});
socket.on("download_started", (data) => {
// Individual download started
// data: { serie_name, episode }
});
socket.on("download_progress", (data) => {
// Download progress update
// data: { serie_name, episode, progress, speed, eta }
});
socket.on("download_complete", (data) => {
// Download completed
// data: { serie_name, episode }
});
socket.on("download_completed", (data) => {
// Legacy event - same as download_complete
});
socket.on("download_failed", (data) => {
// Download failed
// data: { serie_name, episode, error }
});
socket.on("download_error", (data) => {
// Legacy event - same as download_failed
});
socket.on("download_queue_completed", () => {
// All downloads in queue completed
});
socket.on("download_stop_requested", () => {
// Queue stop requested
});
```
##### Scan Events
```javascript
socket.on("scan_started", () => {
// Library scan started
});
socket.on("scan_progress", (data) => {
// Scan progress update
// data: { current, total, percentage }
});
socket.on("scan_completed", (data) => {
// Scan completed
// data: { total_series, new_series, updated_series }
});
socket.on("scan_failed", (data) => {
// Scan failed
// data: { error }
});
```
### Backend WebSocket Requirements
The backend WebSocket implementation (`src/server/api/websocket.py`) should:
1. **Accept connections at** `/ws/connect`
2. **Handle room management** (join/leave messages)
3. **Broadcast events** to appropriate rooms
4. **Support message format**:
```json
{
"event": "event_name",
"data": { ... }
}
```
## Theme System
### Theme Implementation
The application supports light and dark modes with persistence.
#### Theme Toggle
```javascript
// Toggle theme
document.documentElement.setAttribute("data-theme", "light|dark");
// Store preference
localStorage.setItem("theme", "light|dark");
// Load on startup
const savedTheme = localStorage.getItem("theme") || "light";
document.documentElement.setAttribute("data-theme", savedTheme);
```
#### CSS Variables
Themes are defined using CSS custom properties:
```css
:root[data-theme="light"] {
--bg-primary: #ffffff;
--bg-secondary: #f5f5f5;
--text-primary: #000000;
--text-secondary: #666666;
--accent-color: #0078d4;
/* ... more variables */
}
:root[data-theme="dark"] {
--bg-primary: #1e1e1e;
--bg-secondary: #2d2d2d;
--text-primary: #ffffff;
--text-secondary: #cccccc;
--accent-color: #60a5fa;
/* ... more variables */
}
```
### Fluent UI Design Principles
The frontend follows Microsoft Fluent UI design guidelines:
- **Rounded corners**: 4px border radius
- **Shadows**: Subtle elevation shadows
- **Transitions**: Smooth 200-300ms transitions
- **Typography**: System font stack
- **Spacing**: 8px grid system
- **Colors**: Accessible color palette
## Authentication Flow
### Authentication States
```javascript
// State management
const authStates = {
UNAUTHENTICATED: "unauthenticated",
AUTHENTICATED: "authenticated",
SETUP_REQUIRED: "setup_required",
};
```
### Authentication Check
On page load, the application checks authentication status:
```javascript
async checkAuthentication() {
// Skip check on public pages
const currentPath = window.location.pathname;
if (currentPath === '/login' || currentPath === '/setup') {
return;
}
try {
const token = localStorage.getItem('access_token');
if (!token) {
window.location.href = '/login';
return;
}
const response = await fetch('/api/auth/status', {
headers: { 'Authorization': `Bearer ${token}` }
});
if (!response.ok) {
if (response.status === 401) {
localStorage.removeItem('access_token');
window.location.href = '/login';
}
}
} catch (error) {
console.error('Auth check failed:', error);
window.location.href = '/login';
}
}
```
### Login Flow
```javascript
async login(password) {
try {
const response = await fetch('/api/auth/login', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ password })
});
if (response.ok) {
const data = await response.json();
localStorage.setItem('access_token', data.token);
window.location.href = '/';
} else {
// Show error message
this.showError('Invalid password');
}
} catch (error) {
console.error('Login failed:', error);
this.showError('Login failed');
}
}
```
### Logout Flow
```javascript
async logout() {
try {
await fetch('/api/auth/logout', { method: 'POST' });
} finally {
localStorage.removeItem('access_token');
window.location.href = '/login';
}
}
```
## Error Handling
### Frontend Error Display
The application uses toast notifications for errors:
```javascript
showToast(message, type = 'info') {
const toast = document.createElement('div');
toast.className = `toast toast-${type}`;
toast.textContent = message;
document.body.appendChild(toast);
setTimeout(() => {
toast.classList.add('show');
}, 100);
setTimeout(() => {
toast.classList.remove('show');
setTimeout(() => toast.remove(), 300);
}, 3000);
}
```
### API Error Handling
```javascript
async function handleApiError(error, response) {
if (response) {
const data = await response.json().catch(() => ({}));
// Show user-friendly error message
const message = data.message || `Error: ${response.status}`;
this.showToast(message, "error");
// Log details for debugging
console.error("API Error:", {
status: response.status,
error: data.error,
message: data.message,
details: data.details,
});
// Handle specific status codes
if (response.status === 401) {
// Redirect to login
localStorage.removeItem("access_token");
window.location.href = "/login";
}
} else {
// Network error
this.showToast("Network error. Please check your connection.", "error");
console.error("Network error:", error);
}
}
```
### Expected Error Response Format
The backend should return errors in this format:
```json
{
"success": false,
"error": "ERROR_CODE",
"message": "Human-readable error message",
"details": {
"field": "error_field",
"reason": "specific_reason"
},
"request_id": "uuid"
}
```
## Localization
The application includes a localization system (`localization.js`) for multi-language support.
### Localization Usage
```javascript
// Initialize localization
const localization = new Localization();
// Set language
localization.setLanguage("en"); // or 'de', 'es', etc.
// Get translation
const text = localization.get("key", "default_value");
// Update all page text
localization.updatePageText();
```
### Text Keys
Elements with `data-text` attributes are automatically translated:
```html
<span data-text="download-queue">Download Queue</span>
<button data-text="start-download">Start Download</button>
```
### Adding New Translations
Translations are defined in `localization.js`:
```javascript
const translations = {
en: {
"download-queue": "Download Queue",
"start-download": "Start Download",
// ... more keys
},
de: {
"download-queue": "Download-Warteschlange",
"start-download": "Download starten",
// ... more keys
},
};
```
## Accessibility Features
The application includes comprehensive accessibility support.
### Keyboard Navigation
All interactive elements are keyboard accessible:
- **Tab/Shift+Tab**: Navigate between elements
- **Enter/Space**: Activate buttons
- **Escape**: Close modals/dialogs
- **Arrow Keys**: Navigate lists
Custom keyboard shortcuts are defined in `keyboard_shortcuts.js`.
### Screen Reader Support
ARIA labels and live regions are implemented:
```html
<button aria-label="Start download" aria-describedby="download-help">
<i class="fas fa-download" aria-hidden="true"></i>
</button>
<div role="status" aria-live="polite" id="status-message"></div>
```
### Color Contrast
The application ensures WCAG AA compliance for color contrast:
- Normal text: 4.5:1 minimum
- Large text: 3:1 minimum
- Interactive elements: 3:1 minimum
`color_contrast_compliance.js` validates contrast ratios.
### Touch Support
Touch gestures are supported for mobile devices:
- **Swipe**: Navigate between sections
- **Long press**: Show context menu
- **Pinch**: Zoom (where applicable)

# Series Identifier Standardization - Validation Instructions
## Overview
This document provides comprehensive instructions for AI agents to validate the **Series Identifier Standardization** change across the Aniworld codebase. The change standardizes `key` as the primary identifier for series and relegates `folder` to metadata-only status.
## Summary of the Change
| Field | Purpose | Usage |
| -------- | ------------------------------------------------------------------------------ | --------------------------------------------------------------- |
| `key` | **Primary Identifier** - Provider-assigned, URL-safe (e.g., `attack-on-titan`) | All lookups, API operations, database queries, WebSocket events |
| `folder` | **Metadata Only** - Filesystem folder name (e.g., `Attack on Titan (2013)`) | Display purposes, filesystem operations only |
| `id` | **Database Primary Key** - Internal auto-increment integer | Database relationships only |
---
## Validation Checklist
### Phase 2: Application Layer Services
**Files to validate:**
1. **`src/server/services/anime_service.py`**
- [ ] Class docstring explains `key` vs `folder` convention
- [ ] All public methods accept `key` parameter for series identification
- [ ] No methods accept `folder` as an identifier parameter
- [ ] Event handler methods document key/folder convention
- [ ] Progress tracking uses `key` in progress IDs where possible
2. **`src/server/services/download_service.py`**

conda run -n AniWorld python -m pytest tests/api/test_anime_endpoints.py -v
# Search tests for identifier usage
grep -rn "key.*identifier\|folder.*metadata" tests/ --include="*.py"
```
---
## Common Issues to Check
### 1. Inconsistent Naming
Look for inconsistent parameter names:
- `serie_key` vs `series_key` vs `key`
- `serie_id` should refer to `key`, not database `id`
- `serie_folder` vs `folder`
### 2. Missing Documentation
Check that ALL models, services, and APIs document:
- What `key` is and how to use it
- That `folder` is metadata only
### 3. Legacy Code Patterns
Search for deprecated patterns:
```python
# Bad - using folder for lookup
series = get_by_folder(folder_name)
# Good - using key for lookup
series = get_by_key(series_key)
```
### 4. API Response Consistency
Verify all API responses include:
- `key` field (primary identifier)
- `folder` field (optional, for display)
### 5. Frontend Data Flow
Verify the frontend:
- Stores `key` in selection sets
- Passes `key` to API calls
- Uses `folder` only for display
---
## Deprecation Warnings
The following should have deprecation warnings (for removal in v3.0.0):
1. Any `get_by_folder()` or `GetByFolder()` methods
2. Any API endpoints that accept `folder` as a lookup parameter
3. Any frontend code that uses `folder` for identification
**Example deprecation:**
```python
import warnings
def get_by_folder(self, folder: str):
"""DEPRECATED: Use get_by_key() instead."""
warnings.warn(
"get_by_folder() is deprecated, use get_by_key(). "
"Will be removed in v3.0.0",
DeprecationWarning,
stacklevel=2
)
# ... implementation
```
---

# Logging Configuration
This document describes the logging setup for the Aniworld FastAPI application.
## Overview
The application uses Python's built-in `logging` module with both console and file output. All logs are written to:
- **Console**: Colored output for development
- **Log File**: `logs/fastapi_app.log` with detailed timestamps
## Log Levels
By default, the application logs at `INFO` level. You can change this by setting the `LOG_LEVEL` environment variable:
```bash
export LOG_LEVEL=DEBUG # More verbose
export LOG_LEVEL=INFO # Default
export LOG_LEVEL=WARNING # Less verbose
export LOG_LEVEL=ERROR # Errors only
```
Or in your `.env` file:
```
LOG_LEVEL=INFO
```
## Running the Server
### Option 1: Using the run_server.py script (Recommended)
```bash
conda run -n AniWorld python run_server.py
```
This script uses the custom uvicorn logging configuration that ensures proper console and file logging.
### Option 2: Using the shell script
```bash
./start_server.sh
```
### Option 3: Using uvicorn directly
```bash
conda run -n AniWorld python -m uvicorn src.server.fastapi_app:app --host 127.0.0.1 --port 8000 --reload
```
**Note**: When using `conda run`, console output may not be visible in real-time. The logs will still be written to the file.
## Log File Location
All logs are written to: `logs/fastapi_app.log`
To view logs in real-time:
```bash
tail -f logs/fastapi_app.log
```
## Log Format
### Console Output
```
INFO: Starting FastAPI application...
INFO: Server running on http://127.0.0.1:8000
```
### File Output
```
2025-10-25 17:31:19 - aniworld - INFO - Starting FastAPI application...
2025-10-25 17:31:19 - aniworld - INFO - Server running on http://127.0.0.1:8000
```
## What Gets Logged
The application logs:
- **Startup/Shutdown**: Application lifecycle events
- **Configuration**: Loaded settings and configuration
- **HTTP Requests**: Via uvicorn.access logger
- **Errors**: Exception tracebacks with full context
- **WebSocket Events**: Connection/disconnection events
- **Download Progress**: Progress updates for anime downloads
- **File Operations**: File creation, deletion, scanning
## Logger Names
Different parts of the application use different logger names:
- `aniworld`: Main application logger
- `uvicorn.error`: Uvicorn server errors
- `uvicorn.access`: HTTP request logs
- `src.core.SeriesApp`: Core anime logic
- `src.core.SerieScanner`: File scanning operations
- `src.server.*`: Web API endpoints and services
## Programmatic Usage
To use logging in your code:
```python
from src.infrastructure.logging import get_logger
logger = get_logger(__name__)
logger.info("This is an info message")
logger.warning("This is a warning")
logger.error("This is an error", exc_info=True) # Includes traceback
```
## Log Rotation
Log files can grow large over time. Consider implementing log rotation:
```bash
# Archive old logs
mkdir -p logs/archived
mv logs/fastapi_app.log logs/archived/fastapi_app_$(date +%Y%m%d_%H%M%S).log
```
Or use Python's `RotatingFileHandler` (can be added to `src/infrastructure/logging/logger.py`).
## Troubleshooting
### No console output when using `conda run`
This is a known limitation of `conda run`. The logs are still being written to the file. To see console output:
1. Use the log file: `tail -f logs/fastapi_app.log`
2. Or run without conda: `python run_server.py` (after activating environment with `conda activate AniWorld`)
### Log file not created
- Check that the `logs/` directory exists (it's created automatically)
- Verify write permissions on the `logs/` directory
- Check the `LOG_LEVEL` environment variable
### Too much logging
Set a higher log level:
```bash
export LOG_LEVEL=WARNING
```
### Missing logs
- Check that you're using the logger, not `print()`
- Verify the log level is appropriate for your messages
- Ensure the logger is properly configured (should happen automatically on startup)

# Progress Service Architecture
## Overview
The ProgressService serves as the **single source of truth** for all real-time progress tracking in the Aniworld application. This architecture follows a clean, decoupled design where progress updates flow through a well-defined pipeline.
## Architecture Diagram
```
┌─────────────┐
│ SeriesApp │ ← Core download/scan logic
└──────┬──────┘
│ Events (download_status, scan_status)
┌─────────────────┐
│ AnimeService │ ← Subscribes to SeriesApp events
└────────┬────────┘
│ Forwards events
┌──────────────────┐
│ ProgressService │ ← Single source of truth for progress
└────────┬─────────┘
│ Emits events to subscribers
┌──────────────────┐
│ WebSocketService │ ← Subscribes to progress events
└──────────────────┘
Connected clients receive real-time updates
```
## Components
### 1. SeriesApp (Core Layer)
**Location**: `src/core/SeriesApp.py`
**Responsibilities**:
- Execute actual downloads and scans
- Fire events with detailed progress information
- Manage download state and error handling
**Events**:
- `download_status`: Fired during downloads
- `started`: Download begins
- `progress`: Progress updates (percent, speed, ETA)
- `completed`: Download finished successfully
- `failed`: Download encountered an error
- `scan_status`: Fired during library scans
- `started`: Scan begins
- `progress`: Scan progress updates
- `completed`: Scan finished
- `failed`: Scan encountered an error
- `cancelled`: Scan was cancelled
### 2. AnimeService (Service Layer)
**Location**: `src/server/services/anime_service.py`
**Responsibilities**:
- Subscribe to SeriesApp events
- Translate SeriesApp events into ProgressService updates
- Provide async interface for web layer
**Event Handlers**:
```python
def _on_download_status(self, args):
"""Translates download events to progress service."""
if args.status == "started":
await progress_service.start_progress(...)
elif args.status == "progress":
await progress_service.update_progress(...)
elif args.status == "completed":
await progress_service.complete_progress(...)
elif args.status == "failed":
await progress_service.fail_progress(...)
def _on_scan_status(self, args):
"""Translates scan events to progress service."""
# Similar pattern as download_status
```
### 3. ProgressService (Service Layer)
**Location**: `src/server/services/progress_service.py`
**Responsibilities**:
- Central progress tracking for all operations
- Maintain active and historical progress records
- Calculate percentages and rates
- Emit events to subscribers (event-based architecture)
**Progress Types**:
- `DOWNLOAD`: Individual episode downloads
- `SCAN`: Library scans for missing episodes
- `QUEUE`: Download queue operations
- `SYSTEM`: System-level operations
- `ERROR`: Error notifications
**Event System**:
```python
# Subscribe to progress events
def subscribe(event_name: str, handler: Callable[[ProgressEvent], None])
def unsubscribe(event_name: str, handler: Callable[[ProgressEvent], None])
# Internal event emission
async def _emit_event(event: ProgressEvent)
```
**Key Methods**:
```python
async def start_progress(progress_id, progress_type, title, ...):
"""Start tracking a new operation."""
async def update_progress(progress_id, current, total, message, ...):
"""Update progress for an ongoing operation."""
async def complete_progress(progress_id, message, ...):
"""Mark operation as completed."""
async def fail_progress(progress_id, error_message, ...):
"""Mark operation as failed."""
```
### 4. DownloadService (Service Layer)
**Location**: `src/server/services/download_service.py`
**Responsibilities**:
- Manage download queue (FIFO processing)
- Track queue state (pending, active, completed, failed)
- Persist queue to disk
- Use ProgressService for queue-related updates
**Progress Integration**:
```python
# Queue operations notify via ProgressService
await progress_service.update_progress(
progress_id="download_queue",
message="Added 3 items to queue",
metadata={
"action": "items_added",
"queue_status": {...}
},
force_broadcast=True,
)
```
**Note**: DownloadService does NOT directly broadcast. Individual download progress flows through:
`SeriesApp → AnimeService → ProgressService → WebSocket`
### 5. WebSocketService (Service Layer)
**Location**: `src/server/services/websocket_service.py`
**Responsibilities**:
- Manage WebSocket connections
- Support room-based messaging
- Broadcast progress updates to clients
- Handle connection lifecycle
**Integration**:
WebSocketService subscribes to ProgressService events:
```python
async def lifespan(app: FastAPI):
# Get services
progress_service = get_progress_service()
ws_service = get_websocket_service()
# Define event handler
async def progress_event_handler(event) -> None:
"""Handle progress events and broadcast via WebSocket."""
message = {
"type": event.event_type,
"data": event.progress.to_dict(),
}
await ws_service.manager.broadcast_to_room(message, event.room)
# Subscribe to progress events
progress_service.subscribe("progress_updated", progress_event_handler)
```
## Data Flow Examples
### Example 1: Episode Download
1. **User triggers download** via API endpoint
2. **DownloadService** queues the download
3. **DownloadService** starts processing → calls `anime_service.download()`
4. **AnimeService** calls `series_app.download()`
5. **SeriesApp** fires `download_status` events:
- `started` → AnimeService → ProgressService → WebSocket → Client
- `progress` (multiple) → AnimeService → ProgressService → WebSocket → Client
- `completed` → AnimeService → ProgressService → WebSocket → Client
### Example 2: Library Scan
1. **User triggers scan** via API endpoint
2. **AnimeService** calls `series_app.rescan()`
3. **SeriesApp** fires `scan_status` events:
- `started` → AnimeService → ProgressService → WebSocket → Client
- `progress` (multiple) → AnimeService → ProgressService → WebSocket → Client
- `completed` → AnimeService → ProgressService → WebSocket → Client
### Example 3: Queue Management
1. **User adds items to queue** via API endpoint
2. **DownloadService** adds items to internal queue
3. **DownloadService** notifies via ProgressService:
```python
await progress_service.update_progress(
progress_id="download_queue",
message="Added 5 items to queue",
metadata={"queue_status": {...}},
force_broadcast=True,
)
```
4. **ProgressService** → WebSocket → Client receives queue update
## Benefits of This Architecture
### 1. **Single Source of Truth**
- All progress tracking goes through ProgressService
- Consistent progress reporting across the application
- Easy to monitor and debug
### 2. **Decoupling**
- Core logic (SeriesApp) doesn't know about web layer
- Services can be tested independently
- Easy to add new progress consumers (e.g., CLI, GUI)
### 3. **Type Safety**
- Strongly typed progress updates
- Enum-based progress types and statuses
- Clear data contracts
### 4. **Flexibility**
- Multiple subscribers can listen to progress events
- Room-based WebSocket messaging
- Metadata support for custom data
- Multiple concurrent progress operations
### 5. **Maintainability**
- Clear separation of concerns
- Single place to modify progress logic
- Easy to extend with new progress types or subscribers
### 6. **Scalability**
- Event-based architecture supports multiple consumers
- Isolated error handling per subscriber
- No single point of failure
## Progress IDs
Progress operations are identified by unique IDs:
- **Downloads**: `download_{serie_folder}_{season}_{episode}`
- **Scans**: `library_scan`
- **Queue**: `download_queue`
## WebSocket Messages
Clients receive progress updates in this format:
```json
{
"type": "download_progress",
"data": {
"id": "download_naruto_1_1",
"type": "download",
"status": "in_progress",
"title": "Downloading Naruto",
"message": "S01E01",
"percent": 45.5,
"current": 45,
"total": 100,
"metadata": {},
"started_at": "2025-11-07T10:00:00Z",
"updated_at": "2025-11-07T10:05:00Z"
}
}
```
## Configuration
### Startup (fastapi_app.py)
```python
@asynccontextmanager
async def lifespan(app: FastAPI):
# Initialize services
progress_service = get_progress_service()
ws_service = get_websocket_service()
# Define event handler
async def progress_event_handler(event) -> None:
"""Handle progress events and broadcast via WebSocket."""
message = {
"type": event.event_type,
"data": event.progress.to_dict(),
}
await ws_service.manager.broadcast_to_room(message, event.room)
# Subscribe to progress events
progress_service.subscribe("progress_updated", progress_event_handler)
```
### Service Initialization
```python
# AnimeService automatically subscribes to SeriesApp events
anime_service = AnimeService(series_app)
# DownloadService uses ProgressService for queue updates
download_service = DownloadService(anime_service)
```
## Migration Notes
### What Changed
**Before (Callback-based)**:
- ProgressService had a single `set_broadcast_callback()` method
- Only one consumer could receive updates
- Direct coupling between ProgressService and WebSocketService
**After (Event-based)**:
- ProgressService uses `subscribe()` and `unsubscribe()` methods
- Multiple consumers can subscribe to progress events
- Loose coupling - ProgressService doesn't know about subscribers
- Clean event flow: SeriesApp → AnimeService → ProgressService → Subscribers
### Removed
1. **ProgressService**:
- `set_broadcast_callback()` method
- `_broadcast_callback` attribute
- `_broadcast()` method
### Added
1. **ProgressService**:
- `ProgressEvent` dataclass to encapsulate event data
- `subscribe()` method for event subscription
- `unsubscribe()` method to remove handlers
- `_emit_event()` method for broadcasting to all subscribers
- `_event_handlers` dictionary to track subscribers
2. **fastapi_app.py**:
- Event handler function `progress_event_handler`
- Uses `subscribe()` instead of `set_broadcast_callback()`
### Benefits of Event-Based Design
1. **Multiple Subscribers**: Can now have multiple services listening to progress
```python
# WebSocket for real-time updates
progress_service.subscribe("progress_updated", websocket_handler)
# Metrics for analytics
progress_service.subscribe("progress_updated", metrics_handler)
# Logging for debugging
progress_service.subscribe("progress_updated", logging_handler)
```
2. **Isolated Error Handling**: If one subscriber fails, others continue working
3. **Dynamic Subscription**: Handlers can subscribe/unsubscribe at runtime
4. **Extensibility**: Easy to add new features without modifying ProgressService
## Testing
### Unit Tests
- Test each service independently
- Mock ProgressService for services that use it
- Verify event handler logic
### Integration Tests
- Test full flow: SeriesApp → AnimeService → ProgressService → WebSocket
- Verify progress updates reach clients
- Test error handling
### Example Test
```python
async def test_download_progress_flow():
# Setup
progress_service = ProgressService()
events_received = []
async def mock_event_handler(event):
events_received.append(event)
progress_service.subscribe("progress_updated", mock_event_handler)
# Execute
await progress_service.start_progress(
progress_id="test_download",
progress_type=ProgressType.DOWNLOAD,
title="Test"
)
# Verify
assert len(events_received) == 1
assert events_received[0].event_type == "download_progress"
assert events_received[0].progress.id == "test_download"
```
## Future Enhancements
1. **Progress Persistence**: Save progress to database for recovery
2. **Progress History**: Keep detailed history for analytics
3. **Rate Limiting**: Throttle progress updates to prevent spam
4. **Progress Aggregation**: Combine multiple progress operations
5. **Custom Rooms**: Allow clients to subscribe to specific progress types

# 🎯 CRITICAL: Series Identifier Standardization
## Overview
**Problem:** The codebase currently uses multiple identifiers inconsistently:
- `key` (provider identifier, e.g., "attack-on-titan")
- `folder` (filesystem folder name, e.g., "Attack on Titan (2013)")
- `serie_id` (sometimes key, sometimes folder)
- `serie_folder` (filesystem path used as identifier)
**Solution:** Standardize on `key` as the single source of truth for all series identification.
**Benefits:**
- Single, consistent identifier throughout the codebase
- `key` is unique, provider-assigned, URL-safe
- `folder` becomes metadata only (not used for lookups)
- Clearer separation of concerns
- Easier to maintain and debug
**Scope:** This affects core logic, services, API endpoints, frontend, WebSocket events, and tests.

All tasks completed:
- **Task 8.1**: Updated `infrastructure.md` with enhanced identifier convention section including table format, key format requirements, migration notes, and code examples
- **Task 8.2**: Updated `docs/README.md` with series identifier convention section, updated `docs/api_reference.md` with key-based API examples
- **Task 8.3**: Added deprecation warnings with Python's `warnings` module to:
- `SerieList.get_by_folder()` in `src/core/entities/SerieList.py`
- Folder fallback lookup in `src/server/api/anime.py`
- `validate_series_key_or_folder()` in `src/server/utils/validators.py`
All deprecation warnings include removal timeline (v3.0.0) and guidance to use `key` instead.
---
### Phase 9: Final Validation ✅ **Completed November 28, 2025**
All validation tasks completed:
- **Task 9.1**: Full test suite passes (1006 tests). Fixed search API key extraction from link slugs.
- **Task 9.2**: Manual end-to-end testing verified - login, search (returns key), queue status (uses serie_id as key). All APIs work correctly with key identifier.
- **Task 9.3**: Performance tests pass (19 tests). Key lookup is O(1) at ~0.11μs per lookup.

## 🎉 Series Identifier Standardization Complete!
All phases of the identifier standardization have been successfully completed. The codebase now consistently uses `key` as the primary identifier for series throughout:
- Core entities and data layer
- Application layer services
- API endpoints and responses
- Frontend integration
- Database operations
- WebSocket events
The `folder` field remains as metadata only and is no longer used for lookups. Deprecation warnings are in place for any legacy folder-based lookups, scheduled for removal in v3.0.0.
