Signals in Superdesk
====================

We use `Flask signals <http://flask.pocoo.org/docs/1.0/signals/>`_ to allow custom development on Superdesk.

Usage::

    from superdesk import item_update


    def my_item_update_handler(sender, item, **kwargs):
        print('item updated', item)


    def init_app(app):

        item_update.connect(my_item_update_handler)
