from flasgger import swag_from, Swagger


def create_app():
    app = Flask(__name__, instance_relative_config=True)
    app_config = {}
    app.config.from_mapping(app_config)
    app.config['SWAGGER'] = {
        'title': 'Swagger Callbacks',
        'openapi': '3.0.3'
    }
    Swagger(app, template={
        'title': 'Swagger Callbacks',
        'openapi': '3.0.3',
        "components": {
            "securitySchemes": {

            }
        }
    })

    return app
