+ExtDirect

+:name: ``extdirect``

+
+Implements the `Ext Direct`_ protocol.
+
+The provider definition is made available at the ``/extdirect/api.js`` subpath.
+
+The router url is ``/extdirect/router[/subnamespace]``.
+
+Options
+~~~~~~~
+
+:namespace: Base namespace of the api. Used for the provider definition.
+:params_notation: Default notation for function call parameters. Can be
+    overriden for individual functions by adding the
+    ``extdirect_params_notation`` extra option to @expose.
+
+    The possible notations are :
+
+    -   ``'named'``  -- The function will take only one object parameter
+        in which each property will be one of the parameters.
+    -   ``'positional'`` -- The function will take as many parameters as
+        the function has, and their position will determine which parameter
+        they are.
+
+expose extra options
+~~~~~~~~~~~~~~~~~~~~
+
+:extdirect_params_notation: Override the params_notation for a particular
+    function.
