Flask-JS-BS
This is my very minimal Flask+JS boilerplate. It has templating, jQuery, Bootstrap, and MaterializeCSS. I use it primarily when I'd like to display some interactive Data/ML charts and visualizations or have the need to rapidly prototype an idea. I don't typically need a DB, User Auth, Form validation etc. for those types of projects; only a server and some quick JS.
Installation
pipenv install
Usage
pipenv run python app.py
