Lifespan Event

spangle supports lifespan events .

Define events in components

As you read this , components have lifecycle event hooks.

class Life:
    async def startup(self):
        # called once while starting server.
        pass

    def shutdown(self):
        # called once before shutdown.
        pass

Define events as functions

You can also create hooks as functions. Components are available in the functions.

@api.on_start
async def startup():
    # called AFTER component's hooks.
    pass

@api.on_stop
def shutdown():
    # called BEFORE component's hooks.
    pass
