- Uses the "Inter" font for a modern look.
- Tailwind CSS styles are included via index.css imported in your React app.
SEO and Social Sharing:
- Meta tags for search engine optimization.
- Open Graph tags for better link previews on social media.
Accessibility:
- The lang attribute is set to "en" for English.
- The viewport meta tag ensures responsiveness on mobile devices.

2. index.css

This CSS file includes Tailwind CSS directives and custom styles for your application.

/* src/index.css */

/* Import Tailwind CSS directives */
@tailwind base;
@tailwind components;
@tailwind utilities;

/* Custom Global Styles */

/* Body Styles */
body {
  @apply bg-gray-50 text-gray-800 font-sans;
}

/* Headings */
h1,
h2,
h3,

  @apply text-blue-600 hover:text-blue-800 transition-colors duration-200;
}

/* Loader Styles */

  border-top-color: #3490dc; /* Customize the color as needed */
  animation: spinner 1.5s linear infinite;
  border: 8px solid #f3f3f3; /* Light gray border */
  border-radius: 50%;

  }
}

/* Custom Button Styles (Optional) */
.button {
  @apply inline-flex items-center justify-center px-6 py-3 border border-transparent text-base font-medium rounded-md shadow-sm transition duration-300 ease-in-out focus:outline-none focus:ring-2 focus:ring-offset-2;
}

.button-primary {
  @apply text-white bg-blue-600 hover:bg-blue-700 focus:ring-blue-500;
}

.button-secondary {
  @apply text-blue-700 bg-blue-100 hover:bg-blue-200 focus:ring-blue-500;
}

Notes:

Tailwind CSS Directives:
- @tailwind base;
- @tailwind components;
- @tailwind utilities;
Custom Styles:
- Global styles for body, headings, and links.
- Loader styles for the loading spinner.
- Optional custom button styles using Tailwind's @apply directive.

3. index.tsx

This is the entry point of your React application.

// src/index.tsx

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import './index.css'; // Import Tailwind CSS and custom styles

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

Notes:

Imports:
- React and ReactDOM for rendering the app.
- App component from ./App.
- index.css for global styles.
Rendering:
- Uses ReactDOM.render to mount the App component into the root div.
- Wrapped in React.StrictMode for highlighting potential problems.

4. App.tsx

The main application component that sets up routing and context providers.

// src/App.tsx

import React, { Suspense, lazy } from 'react';
import { BrowserRouter as Router, Route, Routes, Navigate } from 'react-router-dom';
import { AuthProvider, useAuth } from './context/AuthContext';
import LoadingSpinner from './components/LoadingSpinner';
import ErrorBoundary from './components/ErrorBoundary';

// Lazy-loaded components
const UserDashboard = lazy(() => import('./pages/UserDashboard'));
const AdminDashboard = lazy(() => import('./pages/AdminDashboard'));
const AxiomEditor = lazy(() => import('./pages/AxiomEditor'));
const LoginPage = lazy(() => import('./pages/LoginPage'));
const NotFoundPage = lazy(() => import('./pages/NotFoundPage'));

const ProtectedRoute: React.FC<{ children: JSX.Element }> = ({ children }) => {
  const { isAdmin } = useAuth();
  return isAdmin ? children : <Navigate to="/login" />;
};

const App: React.FC = () => {
  return (
    <AuthProvider>
      <Router>
        <ErrorBoundary>
          <Suspense fallback={<LoadingSpinner />}>
            <Routes>
              <Route path="/" element={<UserDashboard />} />
              <Route path="/login" element={<LoginPage />} />
              <Route
                path="/admin/*"
                element={
                  <ProtectedRoute>
                    <AdminRoutes />
                  </ProtectedRoute>
                }
              />
              <Route path="*" element={<NotFoundPage />} />
            </Routes>
          </Suspense>
        </ErrorBoundary>
      </Router>
    </AuthProvider>
  );
};

const AdminRoutes: React.FC = () => (
  <Routes>
    <Route path="/" element={<AdminDashboard />} />
    <Route path="axioms" element={<AxiomEditor />} />
    {/* Add more admin routes here */}
  </Routes>
);

export default App;

Notes:

Routing:
- Uses react-router-dom for client-side routing.
- Sets up routes for user dashboard, admin dashboard, login page, etc.
Lazy Loading:
- Components are loaded lazily using React.lazy and Suspense to improve performance.
Authentication:
- ProtectedRoute component checks if the user is an admin before granting access to admin routes.
Error Handling:
- ErrorBoundary component catches JavaScript errors and displays a fallback UI.
