:description: This example demonstrates a usage of the Sanic and Dependency Injector.
|
|
|
|
|
|
This example shows how to use ``Dependency Injector`` with `Sanic <https://sanic.readthedocs.io/en/latest/>`_.
|
|
|
|
The example application is a REST API that searches for funny GIFs on the `Giphy <https://giphy.com/>`_.
|
|
|
|
The source code is available on the `Github <https://github.com/ets-labs/python-dependency-injector/tree/master/examples/miniapps/sanic>`_.

Application structure
|
|
---------------------
|
|
|
|
Application has next structure:
|
|
|
|
.. code-block:: bash
|
|
|
|
./
|
|
├── giphynavigator/
|
|
│ ├── __init__.py
|
|
│ ├── __main__.py
|

│ ├── application.py
|
|
│ ├── containers.py
|
|
│ ├── giphy.py

Container
|
|
---------
|
|
|
|
Declarative container is defined in ``giphynavigator/containers.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/sanic/giphynavigator/containers.py
|
|
:language: python
|
|
|
|
Handlers
|
|
--------
|
|
|
|
Handler has dependencies on search service and some config options. The dependencies are injected
|
|
using :ref:`wiring` feature.
|
|
|
|
Listing of ``giphynavigator/handlers.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/sanic/giphynavigator/handlers.py
|
|
:language: python
|
|
|
|
Application factory
|
|
-------------------
|
|
Application factory creates container, wires it with the ``handlers`` module, creates
|
|
``Sanic`` app and setup routes.
|
|
|
|
Listing of ``giphynavigator/application.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/sanic/giphynavigator/application.py
|
|
:language: python
|
|
|
|
Tests
|
|
-----
|
|
|
|
Tests use :ref:`provider-overriding` feature to replace giphy client with a mock ``giphynavigator/tests.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/sanic/giphynavigator/tests.py
|
|
:language: python
