App Logic
=========

The logic of the Knut app communicates with the `Knut Server
<https://github.com/pearjo/knut-server>`_ via TCP and provides all information
received from the server as properties which can be used in the QML part of the
app aka the :ref:`appui`. At the heart of the app's logic is the
:ref:`knutclient` which is used by each service to communicate to the
server. Each service in the server can be accessed via a dedicated API to which
the :ref:`knutclient` sends a JSON formatted message string. Read the `API
documentations
<https://knut-server.readthedocs.io/en/latest/reference/knutapis.html>`_ for
more information about the message format of each service.
