Rasa Chat
=========

``Rasa Chat`` provides a minimal chat interface shipped with the
Platform. The chat interface is by default available at ``/chat``
once the app is deployed.

Configuring the Rasa Chat UI
----------------------------

Here is an example of how to configure the ``RasaChatInput``, taken
from the example app. ``RASA_API_ENDPOINT_URL`` refers to the endpoint ``Rasa NLU``
on which ``RasaNLU`` listens (typically ``http://<hostname>/api``).

.. code-block:: python

    from rasa_extensions.core.channels.rasa_chat import RasaChatInput
    HOSTNAME = os.environ.get("RASA_PLATFORM_HOSTNAME", "http://localhost")
    input_channel = HttpInputChannel(5001,
                                     "/",
                                     RasaChatInput(urlparse.urljoin(HOSTNAME,
                                                                    os.environ.get("RASA_API_ENDPOINT"))))

Using the Rasa Chat UI
----------------------

To access the UI go to: ``https://<hostname>/chat``.
Log in by using one of the accounts created when you configured
replicated (`Create a User <https://rasahq.github.io/rasa_platform/installation.html#create-a-user>`_).
