FastAPI web framework patterns. Triggers on: fastapi, api endpoint, dependency injection, pydantic model, openapi, swagger, starlette, async api, rest api, uvicorn.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FastAPI Patterns
Modern async API development with FastAPI.
## Basic Application
```python
from fastapi import FastAPI
from contextlib import asynccontextmanager
@asynccontextmanager
async def lifespan(app: FastAPI):
"""Application lifespan - startup and shutdown."""
# Startup
app.state.db = await create_db_pool()
yield
# Shutdown
await app.state.db.close()
app = FastAPI(
title="My API",
version="1.0.0",
lifespan=lifespan,
)
@app.get("/")
async def root():
return {"message": "Hello World"}
```
## Request/Response Models
```python
from pydantic import BaseModel, Field, EmailStr
from datetime import datetime
class UserCreate(BaseModel):
"""Request model with validation."""
name: str = Field(..., min_length=1, max_length=100)
email: EmailStr
age: int = Field(..., ge=0, le=150)
class UserResponse(BaseModel):
"""Response model."""
id: int
name: str
email: EmailStr
created_at: datetime
model_config = {"from_attributes": True} # Enable ORM mode
@app.post("/users", response_model=UserResponse, status_code=201)
async def create_user(user: UserCreate):
db_user = await create_user_in_db(user)

How to install
mdr add aiskillstore/marketplace/python-fastapi-patterns@sha256:5035e3c2f91701ffThe line at the top of this page pins the label git:20260113.222b7de, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
