🛠️ Development

Prerequisites

• Node.js (for development and minification)
• A modern web browser

Setup

1. Clone the repository:

   git clone https://github.com/TolinSimpson/Portable-Notebook.git
   cd Portable-Notebook

2. Install dependencies:

   npm install

Minification Process

The project includes an automated minification process to optimize the notebook for production use. The minification script:

• Compresses JavaScript code
• Minifies CSS styles
• Optimizes HTML structure
• Removes comments and whitespace
• Preserves all functionality

To create a minified version:

npm run minify

This generates notebook-min.html with:

• 20.3% smaller file size (from 42KB to 33.5KB)
• Faster loading times on all devices
• Better mobile performance
• All features preserved

Development Workflow

1. Make changes to notebook.html
2. Test your changes across different screen sizes
3. Run npm run minify to create an optimized version
4. Test the minified version on mobile and desktop

📦 File Structure

• notebook-dev.html - Development version (readable, commented, 42KB)
• notebook.html - Production version (minified, optimized, 33.5KB)
