A minimal example of a Flask web application using htmx and Bootstrap for the front end.

The application uses the following components.

1. Flask for the backend
2. htmx for asynchronous HTTP requests
3. Bootstrap for front end layout

• app/static/ contains the Bootstrap and htmx assets.
• app/templates/ contains the Jinja2 templates used by Flask.
• app/main.py is the Flask application's implementation

To run the application locally use docker-compose up -d. Alternatively, follow these steps.

1. Create and activate a virtual environment

   python -m venv venv
   source venv/bin/activate
   

2. Install dependencies

   pip install -r requirements.txt
   

3. Run the app

   export FLASK_ENV=development
   export FLASK_APP=app.main
   flask run
   

4. Open in your browser: http://localhost:5000

application.service and wsgi.py can be used to deploy the application using Gunicorn. To use nginx as a proxy the following config snippet can be used inside a server section.

    location / {
            include proxy_params;
            proxy_pass http://unix:/var/www/flask-htmx-bootstrap/application.sock;
    }
