✨ Add support for lifespan async context managers (superseding startup and shutdown events). Initial PR #2944 by @uSpike.
Now, instead of using independent startup and shutdown events, you can define that logic in a single function with yield decorated with @asynccontextmanager (an async context manager).
For example:
from contextlib import asynccontextmanager
from fastapi import FastAPI
def fake_answer_to_everything_ml_model(x: float):
return x * 42
ml_models = {}
@asynccontextmanager
async def lifespan(app: FastAPI):
# Load the ML model
ml_models["answer_to_everything"] = fake_answer_to_everything_ml_model
yield
# Clean up the ML models and release the resources
ml_models.clear()
