delbrison / stateful_streamlit_enterprise Goto Github PK

An example of how one can track state between multiple pages in Streamlit without reloading pages.

Inspired by https://gist.github.com/okld/0aba4869ba6fdc8d49132e6974e2e662

In addition to this, it also demonstrates Mypy type-safety with classes, decorators, inheritance, wrapping Streamlit, etc.

Instead of using self you'll find that all data lives in the session sess.

Tested on Python 3.7 and Streamlit 0.73.

1. Create a venv and populate it with pip install -r requirements.txt
2. Generate some sample data for the app python scripts/generate_data.py
3. Start the app with streamlit run src/app.py
4. Run tests (there's one, I haven't gotten to that yet) with pytest
