# asgi-sqlalchemy
ASGI Middleware that manages the lifespan of a database engine and a corresponding session.
## Usage:
### FastAPI:
```python
from contextlib import AsyncContextManager
from collections.abc import AsyncGenerator
from typing_extensions import TypedDict
from fastapi import FastAPI
from asgi_sqlalchemy import DatabaseContext, SessionMiddleware
from asgi_sqlalchemy.fastapi import SessionDependency
class AppState(TypedDict):
db: DatabaseContext
async def lifespan() -> AsyncGenerator[AppState]:
async with DatabaseContext(...) as db:
yield {"db": db}
app = FastAPI()
app.add_middleware(SessionMiddleware)
@app.get("/db")
async def handler(session: SessionDependency) -> str:
# do something with your async session!
```
