Middleware components superseded global hooks in version 0.3 of the
framework. By now, developers should have had enough time to migrate
away from the deprecated feature. If not, they can continue using 0.3
until they are able to migrate.
BREAKING CHANGE: falcon.API no longer accepts `before` and `after`
kwargs to specify global hooks. Applications should migrate
any logic contained in global hooks to reside in middleware
components instead.
Old:
def do_something(req, resp, resource, params):
pass
app = falcon.API(before=[do_something])
New:
class ExampleMiddlewareComponent(object):
def process_resource(self, req, resp, resource):
pass
