Skill Pyfagorass/bookofspells/skills/microsoft/fastapi-router-py

Create FastAPI routers with CRUD operations, authentication dependencies, and proper response models. Use when building REST API endpoints, creating new routes, implementing CRUD operations, or adding authenticated endpoints in FastAPI applications.From its SKILL.md

2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.

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

Best Practices

Pick def or async def per endpoint based on whether you call async I/O; do not mix sync and async blocking calls in one handler.
Manage long-lived resources (DB pools, HTTP clients) in lifespan and inject via Depends; use with/async with for per-request resources.
