Get started in FastAPI, Starlette, and ASGI!

How do startup and shutdown events work in FastAPI, Starlette, and other ASGI applications? ASGI defines startup and shutdown events through the "lifespan" of an application, which it models as a connection between the server and the app. In this video we see the right way to do it in FastAPI, Starlette, and then understand the lifespan connection type in general, which we use to build our own lifespan handler from scratch that mimics what FastAPI does.
