Dependency Injector + Sanic Example
=====================================
Application ``githubnavigator`` is a `Django <https://www.djangoproject.com/>`_ +
`Dependency Injector <http://python-dependency-injector.ets-labs.org/>`_ example application.
Run
---
Create virtual environment:
.. code-block:: bash
virtualenv venv
. venv/bin/activate
Install requirements:
.. code-block:: bash
pip install -r requirements.txt
To run the application do:
.. code-block:: bash
export GIPHY_API_KEY=wBJ2wZG7SRqfrU9nPgPiWvORmloDyuL0
python -m giphynavigator
The output should be something like:
.. code-block::
[2020-09-23 18:16:31 -0400] [48258] [INFO] Goin' Fast @ http://0.0.0.0:8000
[2020-09-23 18:16:31 -0400] [48258] [INFO] Starting worker [48258]
After that visit http://127.0.0.1:8000/ in your browser or use CLI command (``curl``, ``httpie``,
etc). You should see something like:
.. code-block:: json

"query": "Dependency Injector",

.. note::
To create your own Giphy API key follow this
`guide <https://support.giphy.com/hc/en-us/articles/360020283431-Request-A-GIPHY-API-Key>`_.
Test
----
This application comes with the unit tests.
To run the tests do:
.. code-block:: bash
py.test giphynavigator/tests.py --cov=giphynavigator
The output should be something like:
.. code-block::
