FastAPI + Redis example
|
|
=======================
|
|
|
|
.. meta::
|
|
:keywords: Python,Dependency Injection,FastAPI,Redis,Example
|
|
:description: This example demonstrates a usage of the FastAPI, Redis, and Dependency Injector.
|
|
|
|
This example shows how to use ``Dependency Injector`` with `FastAPI <https://fastapi.tiangolo.com/>`_ and
|
|
`Redis <https://redis.io/>`_.
|
|
|
|
The source code is available on the `Github <https://github.com/ets-labs/python-dependency-injector/tree/master/examples/miniapps/fastapi-redis>`_.

Redis
|
|
-----
|
|
|
|
Module ``redis`` defines Redis connection pool initialization and shutdown. See ``fastapiredis/redis.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/fastapi-redis/fastapiredis/redis.py
|
|
:language: python
|
|
|
|
Service
|
|
-------
|
|
|
|
Module ``services`` contains example service. Service has a dependency on Redis connection pool.
|
|
It uses it for getting and setting a key asynchronously. Real life service will do something more meaningful.
|
|
See ``fastapiredis/services.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/fastapi-redis/fastapiredis/services.py
|
|
:language: python
|
|
|
|
Container
|
|
---------
|
|
|
|
Declarative container wires example service with Redis connection pool. See ``fastapiredis/containers.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/fastapi-redis/fastapiredis/containers.py
|
|
:language: python
|
|
|
|
Application
|
|
-----------
|
|
|
|
Module ``application`` creates ``FastAPI`` app, setup endpoint, and init container.
|
|
|
|
Endpoint ``index`` has a dependency on example service. The dependency is injected using :ref:`wiring` feature.
|
|
|
|
Listing of ``fastapiredis/application.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/fastapi-redis/fastapiredis/application.py
|
|
:language: python
|
|
|
|
Tests
|
|
-----
|
|
|
|
Tests use :ref:`provider-overriding` feature to replace example service with a mock. See ``fastapiredis/tests.py``:
|
|
|
|
.. literalinclude:: ../../examples/miniapps/fastapi-redis/fastapiredis/tests.py
|
|
:language: python
