FastAPI + Dependency Injector Example
=====================================

This is a `FastAPI <https://fastapi.tiangolo.com/>`_ +
`Dependency Injector <https://python-dependency-injector.ets-labs.org/>`_ example application.

The example application is a REST API that searches for funny GIFs on the `Giphy <https://giphy.com/>`_.

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
    uvicorn giphynavigator.application:app --reload

The output should be something like:

.. code-block::

   INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
   INFO:     Started reloader process [4795] using watchgod
   INFO:     Started server process [4797]
   INFO:     Waiting for application startup.
   INFO:     Application startup complete.

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
