d S )!JSONProvidera  A standard set of JSON operations for an application. Subclasses
    of this can be used to customize JSON behavior or use different
    JSON libraries.

    To implement a provider for a specific library, subclass this base
    class and implement at least :meth:`dumps` and :meth:`loads`. All
    other methods have default implementations.

    To use a different provider, either subclass ``Flask`` and set
    :attr:`~flask.Flask.json_provider_class` to a provider class, or set
    :attr:`app.json <flask.Flask.json>` to an instance of the class.

    :param app: An application instance. This will be stored as a
        :class:`weakref.proxy` on the :attr:`_app` attribute.
