• Content guidelines and examples
• Testing and deployment procedures

npm run create:page your-tool-name

This automatically:

• ✅ Creates the component file
• ✅ Registers it in routing
• ✅ Sets up basic SEO metadata
• ✅ Generates the correct URL structure

See INTERACTIVE_TOOLS_GUIDE.md for:

• Popular tool categories (Calculators, Visualizations, Linear Algebra, etc.)
• SEO-friendly description templates
• Popular keywords to target
• Examples: Pascal's Triangle, Matrix Inverse, etc.

npm start

Visit http://localhost:3000 to see the home page with all components listed.

Visit http://localhost:3000/xyz to see a specific component.

npm run build

This creates an optimized production build in the build/ directory.

npm run clean

The repository is configured with GitHub Actions to automatically deploy to GitHub Pages when you push to the main branch.

Setup Steps:

1. Go to your repository on GitHub
2. Navigate to Settings → Pages
3. Under Source, select GitHub Actions
4. Update homepage in package.json to match your repo name:

   {
     "homepage": "/your-repo-name"
   }

5. Push your changes to the main branch
6. The workflow will automatically build and deploy your app

If you prefer to deploy manually:

npm run build
npm run deploy

Note: Make sure you have gh-pages installed and configured with your GitHub credentials.

Update the homepage field in package.json to match your GitHub repository name:

{
  "homepage": "/your-repo-name"
}

This ensures all routes work correctly on GitHub Pages.

• Single React App: One React application with React Router
• Multiple Pages: Each page is a single React component in src/pages/
• Automatic Routing: Pages are automatically registered and routed
• Home Page: Lists all available components with links
• Unique URLs: Each component has its own URL like /xyz, /abc, etc.

npm run create:page xyz

This creates:

• src/pages/XyzPage.js - Your component file
• Registers it at route /xyz
• Makes it appear on the home page

Then edit src/pages/XyzPage.js to add your interactive component code!

• Make sure homepage in package.json matches your repo name
• Ensure you're using BrowserRouter with basename (already configured)
• Check that GitHub Pages is set to use GitHub Actions as the source

• Make sure the component is registered in src/pages/index.js
• Check that the component name matches the route (kebab-case)
• Restart the dev server after adding new pages

GPL-2.0

Feel free to add new interactive components! Each component should be self-contained and independent.
