Batteries-included authentication flow in Dash with Dash Pages.

This has landing pages and functions to run the entire authentication flow:

• home
• login
• logout
• register
• forgot password
• change password

This uses flask-login on the backend, taking some inspiration from the very useful dash-flask-login. Data is held in users.db.

The provided .env.example is just an example. Copy that file to a .env file and fill in the details. It's set up this way so you don't accidentally expose your credentials in git. The app won't run correctly if .env doesn't have the required values filled out.

# with plain virtualenv python -m venv venv source venv/bin/activate pip install -r requirements.txt python create_tables.py python app.py # with pipenv pip install pipenv pipenv install --ignore-pipfile pipenv python create_tables.py pipenv run python app.py # with poetry pip install poetry poetry run python create_tables.py poetry run python app.py # either: deactivate virtual environment deactivate

• this uses MailJet as the email API. You need a free MailJet API key
• your send-from email and API key/secret need to be entered in .env
• if you want to use a different email provider, change the send_password_key function in utilities/auth.py
• add pages in pages/. Make sure to register the page at a path with register_page(__name__, pathname="/path")
• the app's basic layout and routing happens in app.py
• app is created and auth is built in server.py
• config is in utilities/config.txt and utilities/config.py

I've provided a Procfile for Heroku, there are many resources for Heroku deployment.

My preferred host is Fly.io. I've included a Dockerfile, .dockerignore, and fly.toml for an example.

# first time fly launch # after any change, deploy an updated version with fly deploy
