A starlette application will always automatically include two middleware classes. `ServerErrorMiddleware` is added as the very outermost middleware, to handle any uncaught errors occurring anywhere in the entire stack. `ExceptionMiddleware` is added as the very innermost middleware, to deal with handled exception cases occurring in the routing or endpoints. * **exception_handlers** - A mapping of either integer status codes, or exception class types onto callables which handle the exceptions. Exception handler callables should be of the form `handler(request, exc) -> response` and may be be either standard functions, or async functions. * **on_startup** - A list of callables to run on application startup. Startup handler callables do not take any arguments, and may be be either standard functions, or async functions. * **on_shutdown** - A list of callables to run on application shutdown. Shutdown handler callables do not take any arguments, and may be be either standard functions, or async functions. * **lifespan** - A lifespan context function, which can be used to perform startup and shutdown tasks. This is a newer style that replaces the `on_startup` and `on_shutdown` handlers. Use one or the other, not both.
