Overview

Implement client-side routing with navigation, lazy loading, protected routes, and state management for multi-page single-page applications.

When to Use

• Multi-page navigation
• URL-based state management
• Protected/guarded routes
• Lazy loading of components
• Query parameter handling

Quick Start

Minimal working example:

// App.tsx
import { BrowserRouter, Routes, Route, Navigate } from 'react-router-dom';
import { Layout } from './components/Layout';
import { Home } from './pages/Home';
import { NotFound } from './pages/NotFound';
import { useAuth } from './hooks/useAuth';
import React from 'react';

// Lazy loaded components
const Dashboard = React.lazy(() => import('./pages/Dashboard'));
const UserProfile = React.lazy(() => import('./pages/UserProfile'));
const Settings = React.lazy(() => import('./pages/Settings'));

// Protected route wrapper
const ProtectedRoute: React.FC<{ children: React.ReactNode }> = ({ children }) => {
  const { isAuthenticated } = useAuth();

  if (!isAuthenticated) {
    return <Navigate to="/login" replace />;
  }

  return <>{children}</>;
};

export const App: React.FC = () => {
// ... (see reference guides for full implementation)
