Flask + Dependency Injector Example
|
|
===================================
|
|
|
|
This is a `Flask <https://flask.palletsprojects.com/>`_ +
|
|
`Dependency Injector <https://python-dependency-injector.ets-labs.org/>`_ example application.
|
|
|
|
The example application helps to search for repositories on the Github.

|
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 FLASK_APP=githubnavigator.application
|
|
export FLASK_ENV=development
|
|
flask run
|
|
|
|
The output should be something like:
|
|
|
|
.. code-block::
|
|
|
|
* Serving Flask app "githubnavigator.application" (lazy loading)
|
|
* Environment: development
|
|
* Debug mode: on
|
|
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
|
|
* Restarting with fsevents reloader
|
|
* Debugger is active!
|
|
* Debugger PIN: 473-587-859
|
|
|
|
After that visit http://127.0.0.1:5000/ in your browser.
|
|
|
|
.. note::
|
|
|
|
Github has a rate limit. When the rate limit is exceed you will see an exception
|
|
``github.GithubException.RateLimitExceededException``. For unauthenticated requests, the rate
|
|
limit allows for up to 60 requests per hour. To extend the limit to 5000 requests per hour you
|
|
need to set personal access token.
|
|
|
|
It's easy:
|
|
|
|
- Follow this `guide <https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token>`_ to create a token.
|
|
- Set a token to the environment variable:
|
|
|
|
.. code-block:: bash
|
|
|
|
export GITHUB_TOKEN=<your token>
|
|
|
|
- Restart the app with ``flask run``
|
|
|
|
