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``
