A blueprint is an object that allows defining application functions without requiring an application object ahead of time. It uses the same decorators as :class:`~flask.Flask`, but defers the need for an application by recording them for later registration. Decorating a function with a blueprint creates a deferred function that is called with :class:`~flask.blueprints.BlueprintSetupState` when the blueprint is registered on an application. See :ref:`blueprints` for more information. .. versionchanged:: 1.1.0 Blueprints have a ``cli`` group to register nested CLI commands. The ``cli_group`` parameter controls the name of the group under the ``flask`` command. .. versionadded:: 0.7 :param name: The name of the blueprint. Will be prepended to each endpoint name. :param import_name: The name of the blueprint package, usually ``__name__``. This helps locate the ``root_path`` for the blueprint. :param static_folder: A folder with static files that should be served by the blueprint's static route. The path is relative to the blueprint's root path. Blueprint static files are disabled by default. :param static_url_path: The url to serve static files from. Defaults to ``static_folder``. If the blueprint does not have a ``url_prefix``, the app's static route will take precedence, and the blueprint's static files won't be accessible. :param template_folder: A folder with templates that should be added to the app's template search path. The path is relative to the blueprint's root path. Blueprint templates are disabled by default. Blueprint templates have a lower precedence than those in the app's templates folder. :param url_prefix: A path to prepend to all of the blueprint's URLs, to make them distinct from the rest of the app's routes. :param subdomain: A subdomain that blueprint routes will match on by default. :param url_defaults: A dict of default values that blueprint routes will receive by default. :param root_path: By default, the blueprint will automatically this based on ``import_name``. In certain situations this automatic detection can fail, so the path can be specified manually instead.
