Définition

class Blueprint(Scaffold):

Description _{[extrait de Blueprint.doc]}

Represents a blueprint, a collection of routes and other
    app-related functions that can be registered on a real application
    later.

    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 :doc:`/blueprints` for more information.

    :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 set
        this based on ``import_name``. In certain situations this
        automatic detection can fail, so the path can be specified
        manually instead.

    .. 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.
