I'll create a complete notes application with a vanilla JavaScript frontend and a Flask backend with SQLite database. Let's start with the backend:

Now, let's create the frontend:

Let's add the CSS:

Now, let's add the JavaScript:

Finally, let's create a README.md file:

git clone https://github.com/yourusername/simple-notes-app.git cd simple-notes-app

python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate

pip install flask flask-cors

python app.py

If you have Python installed:

python -m http.server 8000

simple-notes-app/ ├── app.py # Flask backend ├── notes.db # SQLite database (created automatically) ├── index.html # Frontend HTML ├── styles.css # CSS styles ├── app.js # Frontend JavaScript └── README.md # This file

This simple notes app includes all the requested features:

1. Frontend (JavaScript):

   • Clean HTML structure with responsive design
   • CSS styling for a modern look and feel
   • Vanilla JavaScript for DOM manipulation and API calls

2. Backend (Python):

   • Flask API with endpoints for creating, retrieving, and deleting notes
   • CORS support for cross-origin requests
   • Error handling and validation

3. Database (SQL):

   • SQLite database for storing notes
   • Schema with title, content, and creation timestamp

4. Features:

   • Add new notes with a form
   • View all notes in a responsive grid
   • Delete notes with confirmation
   • Responsive design that works on all devices

To run the application:

1. Start the Flask backend with python app.py
2. Open the index.html file in your browser or serve it with a simple HTTP server

The README provides comprehensive documentation about the features, setup instructions, and usage.
