# setup_swagger(app, swagger_from_file="example_swagger.yaml")


async def index(request):
    return web.Response(text="Welcome home!")

async def my_web_app():
    app = web.Application()
    app.router.add_get('/', index)
    app.router.add_route('GET', "/example1", example_1)
    app.router.add_route('GET', "/example2", example_2)
    setup_swagger(app, swagger_from_file="example_swagger.yaml")
