```
|
|
|
|
- **Django** (`/admin`): Admin interface for data management
|
|
- **FastAPI** (`/api`): REST API and gRPC client
|
|
- **Timeline UI** (`/ui`): React app for video editing
|
|
- **gRPC Server**: Worker communication with progress streaming
|
|
- **Celery**: Job execution via FFmpeg
|
|
|
|

## Code Generation
|
|
|
|
Models are defined in `schema/models/` and generate:
|
|
- Django ORM models
|
|
- Pydantic schemas
|
|
- TypeScript types
|
|
- Protobuf definitions
|
|
|
|
```bash
|
|
# Regenerate all
|
|
python schema/generate.py --all
|
|
|
|
# Or specific targets
|
|
python schema/generate.py --django
|
|
python schema/generate.py --pydantic
|
|
python schema/generate.py --typescript
|
|
python schema/generate.py --proto
|
|
```
|
