-

-    * **routes** - A list of routes to serve incoming HTTP and WebSocket requests.
-    * **middleware** - A list of middleware to run for every request. 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 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 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 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.
