Application factory:

# src/app/main.py
from contextlib import asynccontextmanager

from fastapi import FastAPI
from fastapi.middleware.cors import CORSMiddleware

from app.config import settings
from app.db.session import engine
from app.db.base import Base
from app.middleware import TimingMiddleware
from app.routers import users, posts, auth


@asynccontextmanager
async def lifespan(app: FastAPI):
    """Startup and shutdown events."""
    # Startup: create tables (use Alembic in production)
    async with engine.begin() as conn:
        await conn.run_sync(Base.metadata.create_all)
    yield
    # Shutdown: dispose engine
    await engine.dispose()


def create_app() -> FastAPI:
    app = FastAPI(
        title=settings.app_name,
        version="1.0.0",
        docs_url="/docs" if settings.debug else None,
        redoc_url="/redoc" if settings.debug else None,
        lifespan=lifespan,
    )

    # Middleware (order matters: last added = first executed)
    app.add_middleware(TimingMiddleware)
    app.add_middleware(
        CORSMiddleware,
        allow_origins=settings.cors_origins,
        allow_credentials=True,
        allow_methods=["*"],
        allow_headers=["*"],
    )

    # Routers
    app.include_router(auth.router, prefix="/auth", tags=["auth"])
    app.include_router(users.router, prefix="/users", tags=["users"])
    app.include_router(posts.router, prefix="/posts", tags=["posts"])

    return app


app = create_app()

Settings with Pydantic:

# src/app/config.py
from pydantic_settings import BaseSettings, SettingsConfigDict


class Settings(BaseSettings):
    model_config = SettingsConfigDict(
        env_file=".env",
        env_file_encoding="utf-8",
        case_sensitive=False,
    )

    app_name: str = "My API"
    debug: bool = False
    database_url: str = "postgresql+asyncpg://user:pass@localhost:5432/mydb"
    secret_key: str = "change-me-in-production"
    access_token_expire_minutes: int = 30
    cors_origins: list[str] = ["http://localhost:3000"]


settings = Settings()

Step 2: Design Pydantic v2 Schemas

# src/app/schemas/user.py
from datetime import datetime
from typing import Annotated

from pydantic import BaseModel, ConfigDict, EmailStr, Field, field_validator, computed_field


class UserBase(BaseModel):
    """Shared fields for user schemas."""
    email: EmailStr
    display_name: Annotated[str, Field(min_length=2, max_length=50)]


class UserCreate(UserBase):
    """Schema for creating a user."""
    password: Annotated[str, Field(min_length=8, max_length=128)]

    @field_validator("password")
    @classmethod
    def password_complexity(cls, v: str) -> str:
        if not any(c.isupper() for c in v):
            raise ValueError("Password must contain at least one uppercase letter")
        if not any(c.isdigit() for c in v):
            raise ValueError("Password must contain at least one digit")
        return v


class UserUpdate(BaseModel):
    """Schema for partial user updates."""
    display_name: str | None = None
    email: EmailStr | None = None


class UserResponse(UserBase):
    """Schema for user responses (excludes password)."""
    model_config = ConfigDict(from_attributes=True)

    id: int
    created_at: datetime
    is_active: bool

    @computed_field
    @property
    def member_since_days(self) -> int:
        return (datetime.utcnow() - self.created_at).days


class UserListResponse(BaseModel):
    """Paginated user list."""
    data: list[UserResponse]
    total: int
    page: int
    page_size: int
    has_next: bool

Discriminated union for polymorphic responses:

from typing import Literal
from pydantic import BaseModel


class TextNotification(BaseModel):
    type: Literal["text"] = "text"
    message: str


class ImageNotification(BaseModel):
    type: Literal["image"] = "image"
    image_url: str
    caption: str | None = None


class ActionNotification(BaseModel):
    type: Literal["action"] = "action"
    message: str
    action_url: str
    action_label: str


# FastAPI automatically generates correct OpenAPI schema
Notification = TextNotification | ImageNotification | ActionNotification

Step 3: Implement Dependency Injection

# src/app/dependencies.py
from typing import Annotated, AsyncGenerator

from fastapi import Depends, HTTPException, status
from fastapi.security import OAuth2PasswordBearer
from jose import JWTError, jwt
from sqlalchemy.ext.asyncio import AsyncSession

from app.config import settings
from app.db.session import async_session_factory
from app.models.user import User

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="/auth/token")


async def get_db() -> AsyncGenerator[AsyncSession, None]:
    """Yield a database session and ensure it is closed."""
    async with async_session_factory() as session:
        try:
            yield session
            await session.commit()
        except Exception:
            await session.rollback()
            raise


# Type alias for cleaner signatures
DbSession = Annotated[AsyncSession, Depends(get_db)]


async def get_current_user(
    token: Annotated[str, Depends(oauth2_scheme)],
    db: DbSession,
) -> User:
    """Decode JWT and return the authenticated user."""
    credentials_exception = HTTPException(
        status_code=status.HTTP_401_UNAUTHORIZED,
        detail="Could not validate credentials",
        headers={"WWW-Authenticate": "Bearer"},
    )
    try:
        payload = jwt.decode(token, settings.secret_key, algorithms=["HS256"])
        user_id: int | None = payload.get("sub")
        if user_id is None:
            raise credentials_exception
    except JWTError:
        raise credentials_exception

    user = await db.get(User, user_id)
    if user is None or not user.is_active:
        raise credentials_exception
    return user


CurrentUser = Annotated[User, Depends(get_current_user)]


async def require_admin(user: CurrentUser) -> User:
    """Sub-dependency: require admin role."""
    if user.role != "admin":
        raise HTTPException(
            status_code=status.HTTP_403_FORBIDDEN,
            detail="Admin access required",
        )
    return user


AdminUser = Annotated[User, Depends(require_admin)]

Step 4: Build Route Handlers

# src/app/routers/users.py
from fastapi import APIRouter, HTTPException, Query, status

from app.dependencies import CurrentUser, AdminUser, DbSession
from app.schemas.user import UserCreate, UserUpdate, UserResponse, UserListResponse
from app.services.user_service import UserService

router = APIRouter()


@router.get("", response_model=UserListResponse)
async def list_users(
    db: DbSession,
    page: int = Query(default=1, ge=1),
    page_size: int = Query(default=20, ge=1, le=100),
    search: str | None = Query(default=None, max_length=100),
):
    """List users with pagination and optional search."""
    service = UserService(db)
    users, total = await service.list_users(
        page=page, page_size=page_size, search=search
    )
    return UserListResponse(
        data=users,
        total=total,
        page=page,
        page_size=page_size,
        has_next=(page * page_size) < total,
    )


@router.get("/me", response_model=UserResponse)
async def get_current_user_profile(user: CurrentUser):
    """Get the authenticated user's profile."""
    return user


@router.get("/{user_id}", response_model=UserResponse)
async def get_user(user_id: int, db: DbSession):
    """Get a user by ID."""
    service = UserService(db)
    user = await service.get_by_id(user_id)
    if not user:
        raise HTTPException(status_code=404, detail="User not found")
    return user


@router.post("", response_model=UserResponse, status_code=status.HTTP_201_CREATED)
async def create_user(data: UserCreate, db: DbSession):
    """Create a new user account."""
    service = UserService(db)
    existing = await service.get_by_email(data.email)
    if existing:
        raise HTTPException(status_code=409, detail="Email already registered")
    return await service.create(data)


@router.patch("/{user_id}", response_model=UserResponse)
async def update_user(user_id: int, data: UserUpdate, user: CurrentUser, db: DbSession):
    """Update a user (self or admin)."""
    if user.id != user_id and user.role != "admin":
        raise HTTPException(status_code=403, detail="Not authorized")
    service = UserService(db)
    updated = await service.update(user_id, data)
    if not updated:

    """Delete a user (admin only)."""
    service = UserService(db)
    deleted = await service.delete(user_id)
    if not deleted:
        raise HTTPException(status_code=404, detail="User not found")

Step 5: Middleware Patterns

# src/app/middleware.py
import time
import logging
from collections import defaultdict

from fastapi import Request, Response
from starlette.middleware.base import BaseHTTPMiddleware

logger = logging.getLogger(__name__)


class TimingMiddleware(BaseHTTPMiddleware):

    async def dispatch(self, request: Request, call_next) -> Response:
        start = time.perf_counter()
        response = await call_next(request)
        duration_ms = (time.perf_counter() - start) * 1000
        response.headers["X-Process-Time-Ms"] = f"{duration_ms:.1f}"
        logger.info(
            "%s %s completed in %.1fms (status %d)",
            request.method,
            request.url.path,
            duration_ms,
            response.status_code,
        )
        return response


class RateLimitMiddleware(BaseHTTPMiddleware):
    """Simple in-memory rate limiter (use Redis in production)."""

    def __init__(self, app, requests_per_minute: int = 60):
        super().__init__(app)
        self.rpm = requests_per_minute
        self.requests: dict[str, list[float]] = defaultdict(list)

    async def dispatch(self, request: Request, call_next) -> Response:
        client_ip = request.client.host if request.client else "unknown"
        now = time.time()
        window_start = now - 60

        # Clean old entries and count recent requests
        self.requests[client_ip] = [
            t for t in self.requests[client_ip] if t > window_start
        ]

        if len(self.requests[client_ip]) >= self.rpm:
            return Response(
                content='{"detail":"Rate limit exceeded"}',
                status_code=429,
                media_type="application/json",

            )

        self.requests[client_ip].append(now)
        return await call_next(request)

Step 6: Database Integration (SQLAlchemy Async)

# src/app/db/session.py
from sqlalchemy.ext.asyncio import (
    AsyncSession,
    async_sessionmaker,
    create_async_engine,

Step 7: Background Tasks and WebSockets

Background tasks:

from fastapi import BackgroundTasks

    user = await service.create(data)
    background_tasks.add_task(send_welcome_email, user.email, user.display_name)
    return UserResponse.model_validate(user)

WebSocket endpoint:

from fastapi import WebSocket, WebSocketDisconnect


class ConnectionManager:
    """Manage active WebSocket connections."""

    def __init__(self):
        self.active: list[WebSocket] = []

    async def connect(self, websocket: WebSocket):
        await websocket.accept()
        self.active.append(websocket)

    def disconnect(self, websocket: WebSocket):
        self.active.remove(websocket)

    async def broadcast(self, message: str):
        for connection in self.active:
            await connection.send_text(message)


manager = ConnectionManager()


@router.websocket("/ws/chat")
async def websocket_chat(websocket: WebSocket):
    await manager.connect(websocket)
    try:
        while True:
            data = await websocket.receive_text()

    except WebSocketDisconnect:
        manager.disconnect(websocket)
        await manager.broadcast("A user left the chat")

Step 8: Testing

Shared fixtures:

Step 9: Deployment

uvicorn with gunicorn (production):

# Direct uvicorn (development)
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

# gunicorn with uvicorn workers (production)
gunicorn app.main:app \
  --worker-class uvicorn.workers.UvicornWorker \
  --workers 4 \
  --bind 0.0.0.0:8000 \
  --timeout 120 \
  --access-logfile -

Dockerfile:

FROM python:3.12-slim AS base

ENV PYTHONDONTWRITEBYTECODE=1 \
    PYTHONUNBUFFERED=1

WORKDIR /app

FROM base AS deps
COPY pyproject.toml uv.lock ./
RUN pip install uv && uv sync --frozen --no-dev

FROM base AS runner
COPY --from=deps /app/.venv /app/.venv
ENV PATH="/app/.venv/bin:$PATH"

COPY src/ ./src/

# Non-root user
RUN addgroup --system --gid 1001 appgroup && \
    adduser --system --uid 1001 --ingroup appgroup appuser
USER appuser

EXPOSE 8000

HEALTHCHECK --interval=30s --timeout=5s --retries=3 \
    CMD python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"

CMD ["gunicorn", "app.main:app", \
     "--worker-class", "uvicorn.workers.UvicornWorker", \
     "--workers", "4", \
     "--bind", "0.0.0.0:8000"]

Health check endpoint:

@app.get("/health", include_in_schema=False)
async def health_check(db: DbSession):
    """Health check that verifies database connectivity."""
    try:
        await db.execute(text("SELECT 1"))
        return {"status": "healthy", "database": "connected"}
    except Exception:
        return Response(
            content='{"status":"unhealthy","database":"disconnected"}',
            status_code=503,
            media_type="application/json",
        )

Best Practices

• Use async endpoints for I/O-bound operations: database queries, HTTP calls, file I/O
• Define response models explicitly: prevents leaking internal fields (e.g., hashed_password)
• Use Annotated type aliases for dependencies: DbSession, CurrentUser keep signatures clean
• Validate all input with Pydantic schemas: never trust raw request data
• Use dependency injection, not global state: makes testing trivial with overrides
• Commit in the dependency, not the route: the get_db dependency should commit on success and rollback on error
• Keep routes thin: delegate business logic to service classes
• Use structured logging: include request ID, user ID, and duration in log entries
• Pin dependency versions: use uv.lock or pip-compile for reproducible builds

Common Patterns

Pattern 1: Repository Pattern with Service Layer

# Separate data access (repository) from business logic (service)
class UserRepository:
    def __init__(self, db: AsyncSession):
        self.db = db

    async def find_by_id(self, user_id: int) -> User | None:
        return await self.db.get(User, user_id)

    async def find_by_email(self, email: str) -> User | None:
        result = await self.db.execute(select(User).where(User.email == email))
        return result.scalar_one_or_none()

    async def save(self, user: User) -> User:
        self.db.add(user)
        await self.db.flush()
        await self.db.refresh(user)
        return user


class UserService:
    def __init__(self, repo: UserRepository):
        self.repo = repo

    async def register(self, data: UserCreate) -> User:
        existing = await self.repo.find_by_email(data.email)
        if existing:
            raise ValueError("Email already registered")
        user = User(
            email=data.email,
            display_name=data.display_name,
            hashed_password=hash_password(data.password),
        )
        return await self.repo.save(user)

Pattern 2: Pagination Helper

from typing import TypeVar, Generic, Sequence
from pydantic import BaseModel

T = TypeVar("T")


class PaginatedResponse(BaseModel, Generic[T]):
    data: Sequence[T]
    total: int
    page: int
    page_size: int
    has_next: bool
    has_prev: bool

    @classmethod
    def create(
        cls, data: Sequence[T], total: int, page: int, page_size: int
    ) -> "PaginatedResponse[T]":
        return cls(
            data=data,
            total=total,
            page=page,
            page_size=page_size,
            has_next=(page * page_size) < total,
            has_prev=page > 1,
        )

Common Rationalizations

Verification

• All endpoints have explicit response_model definitions
• Input validation uses Pydantic schemas (not manual checks)
• Passwords are hashed (bcrypt/argon2), never stored in plain text
• JWT tokens have expiration times and are validated on every request
• Database sessions are managed via dependency injection with proper cleanup
• Background tasks do not block the event loop (use async or thread pool)
• CORS is configured with specific origins (not wildcard in production)
• Tests use dependency overrides for database isolation
• Health check endpoint verifies database connectivity
• Dockerfile uses non-root user and multi-stage build
• OpenAPI schema is reviewed and reflects actual API contract
• Rate limiting is applied to authentication endpoints

Iterative Refinement Strategy

This skill is optimized for an iterative approach:

1. Execute: Perform the core steps defined above.
2. Review: Critically analyze the output (coverage, quality, completeness).
3. Refine: If targets aren't met, repeat the specific implementation steps with improved context.
4. Loop: Continue until the definition of done is satisfied.
