A minimal Flask-based “todo list” web application demonstrating basic routing, templating, and in-memory data storage.

• List existing todos
• Add new todos via HTML form
• Delete todos

• Python 3.7 or newer
• pip package manager

1. Clone the repository:

   git clone https://github.com/yourusername/todoapp.git
   cd todoapp

2. (Optional) Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate

3. Install dependencies:

   pip install -r requirements.txt

No additional configuration is required. For production use, consider:

• Disabling debug mode
• Using a persistent datastore (e.g. SQLite, PostgreSQL)
• Serving static assets via a CDN or web server

1. Start the development server:

   python app.py

2. Open your browser at http://localhost:5000/

todoapp/
├── app.py                # Application entry point
├── requirements.txt      # Python dependencies
└── templates/
    └── index.html        # Jinja2 template for main page

1. Persistent storage: Replace the in-memory list with a database model (Flask-SQLAlchemy).
2. User sessions: Add user authentication to support multiple users.
3. API: Expose REST endpoints for client-side frameworks or mobile apps.
