tomevault-io FastAPI Templates
This skill provides production-ready templates and scaffolding patterns for FastAPI applications.
When to Use
- Starting a new FastAPI service or project.
- Adding standard components (Auth, DB, Logging) to an existing app.
- Standardizing project structure across the team.
Project Structure Template
Recommended structure for scalable FastAPI apps:
src/
├── api/
│ ├── v1/
│ │ ├── endpoints/ # Route handlers
│ │ └── api.py # Router aggregation
│ └── deps.py # Dependencies (get_current_user, etc.)
├── core/
│ ├── config.py # Pydantic BaseSettings
│ └── security.py # JWT & Password hashing
├── db/
│ ├── models/ # SQLAlchemy models
│ ├── session.py # DB engine and session factory
│ └── base.py # Import all models here
├── schemas/ # Pydantic models (Request/Response)
├── services/ # Business logic
└── main.py # App entrypoint
Code Templates
1. Standard API Endpoint
from fastapi import APIRouter, Depends, HTTPException
from sqlalchemy.ext.asyncio import AsyncSession
from src.api import deps
from src.schemas.item import ItemCreate, Item
from src.services import item_service
router = APIRouter()
@router.post("/", response_model=Item)
async def create_item(
item_in: ItemCreate,
db: AsyncSession = Depends(deps.get_db),
current_user = Depends(deps.get_current_user),
) -> Item:
"""
Create a new item.
"""
return await item_service.create(db, obj_in=item_in, owner_id=current_user.id)
2. Pydantic Settings
from pydantic_settings import BaseSettings
class Settings(BaseSettings):
PROJECT_NAME: str = "FastAPI App"
DATABASE_URL: str
SECRET_KEY: str
class Config:
case_sensitive = True
env_file = ".env"
settings = Settings()
3. SQLAlchemy Async Model
from sqlalchemy import Column, Integer, String
from src.db.base_class import Base
class Item(Base):
id = Column(Integer, primary_key=True, index=True)
title = Column(String, index=True)
description = Column(String, nullable=True)
