TIL: Dash Memoization, Flask-Dash Integration, and Testing

TIL 2020-07-23

1. Memoizing Dash Callback Responses with Flask-Caching - It’s possible to cache dash callback responses for better performance using flask-caching.

2. Configurable Dash Registration - Always ensure that dash registration in a Flask-Dash app is configurable. You might want to skip loading dash when testing backend-only functionality.

3. pytest-dash Status - pytest-dash has been abandoned since the official dash repository now supports Selenium testing via pytest directly.
