FastAPI Router

Create FastAPI routers following established patterns with proper authentication, response models, and HTTP status codes.

Quick Start

Copy the template from assets/template.py and replace placeholders:

```
{{ResourceName}}
```
→ PascalCase name (e.g.,
```
Project
```
)
```
{{resource_name}}
```
→ snake_case name (e.g.,
```
project
```
)
```
{{resource_plural}}
```
→ plural form (e.g.,
```
projects
```
)

Authentication Patterns

# Optional auth - returns None if not authenticated
current_user: Optional[User] = Depends(get_current_user)

# Required auth - raises 401 if not authenticated
current_user: User = Depends(get_current_user_required)

Response Models

@router.get("/items/{item_id}", response_model=Item)
async def get_item(item_id: str) -> Item:
    ...

@router.get("/items", response_model=list[Item])
async def list_items() -> list[Item]:
    ...

HTTP Status Codes

@router.post("/items", status_code=status.HTTP_201_CREATED)
@router.delete("/items/{id}", status_code=status.HTTP_204_NO_CONTENT)

Integration Steps

Create router in
```
src/backend/app/routers/
```
Mount in
```
src/backend/app/main.py
```
Create corresponding Pydantic models
Create service layer if needed
Add frontend API functions
