# 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
|
||||
|
||||
#### `/api/v1/anime/process/locks` (GET)
|
||||
|
||||
- Returns current lock status for rescan and download processes
|
||||
- Response: `{success: boolean, locks: {rescan: {is_locked: boolean}, download: {is_locked: boolean}}}`
|
||||
- Used to update UI status indicators and disable buttons during operations
|
||||
|
||||
### 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 |
|
||||
| `/api/process/locks/status` | `/api/v1/anime/process/locks` | Check process locks |
|
||||
|
||||
### 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.

### Frontend Integration
|
||||
### Missing API Endpoints
|
||||
|

The following frontend assets already exist and should be reviewed:
|
||||
The following API endpoints are referenced in the frontend but not yet implemented:
|
||||
|
||||
- **Templates**: Located in `src/server/web/templates/`
|
||||
- **JavaScript**: Located in `src/server/web/static/js/` (app.js, queue.js, etc.)
|
||||
- **CSS**: Located in `src/server/web/static/css/`
|
||||
- **Static Assets**: Images and other assets in `src/server/web/static/`
|
||||
|
||||
When working with these files:
|
||||
|
||||
- [] Review existing functionality before making changes
|
||||
- [] Maintain existing UI/UX patterns and design
|
||||
- [] Update API calls to match new FastAPI endpoints
|
||||
- [] Preserve existing WebSocket event handling
|
||||
- [] Keep existing theme and responsive design features
|
||||
- Scheduler API endpoints (`/api/scheduler/`) - Configuration and manual triggers
|
||||
- Logging API endpoints (`/api/logging/`) - Log file management and configuration
|
||||
- Diagnostics API endpoints (`/api/diagnostics/`) - Network diagnostics
|
||||
- Config section endpoints (`/api/config/section/advanced`, `/api/config/directory`, etc.) - May need verification
