FastAPI · Concept

Path operations

Use APIRouter to keep related FastAPI path operations in separate modules. Add shared prefixes, tags, dependencies, and responses, then include the router in the main application.

Syntax

router = APIRouter(prefix="/items", tags=["items"], dependencies=[Depends(get_token_header)], responses={404: {"description": "Not found"}})
app.include_router(router)
