React Router v6 – Multi-Page App Banaye (Routing Guide) 2026

नमस्ते दोस्तों! 🙏
स्वागत है The Easy Master पर!

क्या तुमने कभी सोचा है – React ek Single Page Application (SPA) है, तो multiple pages kaise banayein?

Normal websites (like Amazon, Flipkart) mein:

  • Home page → /
  • Products page → /products
  • Product detail → /products/101
  • Cart page → /cart

Yeh sab different URLs हैं – aur jab tum link click karte ho, toh page reload hota hai।

React Router v6 Routing Hindi में समझना बहुत जरूरी है क्योंकि:

  • React apps mein multi-page feel without page reload – smooth experience
  • URL share karna – kisi ko specific page ka link bhej sakte ho
  • Browser navigation – back/forward buttons kaam karte hain
  • SEO better – different URLs for different content
  • 99% React apps routing use karte hain

Aaj kya seekhoge?

1. React Router v6 Routing Hindi – Introduction

React Router ek library hai jo React apps mein routing add karti hai – bina page reload ke different URLs show karne ke liye।

React Router v6 vs Traditional Websites:

FeatureTraditional WebsiteReact Router v6
Page reloadHar navigation par reload hota haiNo reload – smooth
Navigation speedSlow (waits for server)Instant
State preservationLost on navigationPreserved
User experienceFeels like old webFeels like app
Back/Forward buttonsWorksWorks
Deep linkingWorksWorks

React Router v6 Routing Hindi mein hum ek complete multi-page app banayenge – Home, About, Products, Product Detail, Contact, aur Dashboard with authentication।

2. Installation aur Setup

Step 1: React Router v6 Install Karna

Code
# NPM se install
npm install react-router-dom

# Yarn se install
yarn add react-router-dom

Step 2: Package.json Check Karna

Code
{
  "dependencies": {
    "react-router-dom": "^6.20.0"  // v6 or higher
  }
}

3. BrowserRouter – App ko Router Provide Karna

BrowserRouter whole app ko routing capability deta hai।

main.jsx – Router Setup:

Code
// src/main.jsx
import React from 'react';
import ReactDOM from 'react-dom/client';
import { BrowserRouter } from 'react-router-dom';  // ✅ Import BrowserRouter
import App from './App';

ReactDOM.createRoot(document.getElementById('root')).render(
  <React.StrictMode>
    <BrowserRouter>  {/* ✅ Wrap App with BrowserRouter */}
      <App />
    </BrowserRouter>
  </React.StrictMode>
);

Alternative Router Types:

RouterUse Case
BrowserRouterMost common – for web apps
HashRouterStatic file hosting (no server config)
MemoryRouterTesting / React Native
StaticRouterServer-side rendering

4. Routes aur Route – Pages Define Karna

React Router v6

Routes container hai – jisme hum Route components define karte hain।

App.jsx – Basic Routes:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import Home from './pages/Home';
import About from './pages/About';
import Contact from './pages/Contact';
import Products from './pages/Products';

function App() {
  return (
    <div className="app">
      <h1>My React App</h1>
      
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="/about" element={<About />} />
        <Route path="/contact" element={<Contact />} />
        <Route path="/products" element={<Products />} />
      </Routes>
    </div>
  );
}

export default App;

Page Components:

Code
// src/pages/Home.jsx
function Home() {
  return (
    <div>
      <h2>Home Page</h2>
      <p>Welcome to our website!</p>
    </div>
  );
}

export default Home;

// src/pages/About.jsx
function About() {
  return (
    <div>
      <h2>About Us</h2>
      <p>We are learning React Router v6!</p>
    </div>
  );
}

export default About;

Link – page reload ke bina navigation के लिए (replaces <a href="">)

NavLink – Link jaisa hai, lekin active state deta hai (styling ke liye)

Header Component with Navigation:

Code
// src/components/Header.jsx
import { Link, NavLink } from 'react-router-dom';

function Header() {
  return (
    <header>
      <nav>
        {/* Simple Link */}
        <Link to="/">Home</Link>
        <Link to="/about">About</Link>
        
        {/* NavLink with active styling */}
        <NavLink 
          to="/products" 
          className={({ isActive }) => isActive ? 'active-link' : ''}
          style={({ isActive }) => ({
            color: isActive ? '#61DAFB' : 'white',
            fontWeight: isActive ? 'bold' : 'normal'
          })}
        >
          Products
        </NavLink>
        
        <NavLink to="/contact">Contact</NavLink>
      </nav>
    </header>
  );
}

export default Header;

Complete App with Navigation:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import Header from './components/Header';
import Footer from './components/Footer';
import Home from './pages/Home';
import About from './pages/About';
import Contact from './pages/Contact';
import Products from './pages/Products';

function App() {
  return (
    <div className="app">
      <Header />
      
      <main>
        <Routes>
          <Route path="/" element={<Home />} />
          <Route path="/about" element={<About />} />
          <Route path="/contact" element={<Contact />} />
          <Route path="/products" element={<Products />} />
        </Routes>
      </main>
      
      <Footer />
    </div>
  );
}

export default App;
Code
/* src/App.css */
.active-link {
  color: #61DAFB !important;
  border-bottom: 2px solid #61DAFB;
}

nav a {
  color: white;
  text-decoration: none;
  margin: 0 15px;
  padding: 5px 10px;
}

nav a:hover {
  color: #61DAFB;
}

6. Nested Routes – Layouts aur Child Pages

Nested Routes – common layout share karne के लिए (जैसे header + sidebar same रहे, सिर्फ content change हो)

Layout Component:

Code
// src/layouts/ProductsLayout.jsx
import { Outlet, NavLink } from 'react-router-dom';

function ProductsLayout() {
  return (
    <div className="products-layout">
      <h2>Products Section</h2>
      
      <div className="products-sidebar">
        <NavLink to="all">All Products</NavLink>
        <NavLink to="electronics">Electronics</NavLink>
        <NavLink to="clothing">Clothing</NavLink>
        <NavLink to="books">Books</NavLink>
      </div>
      
      <div className="products-content">
        <Outlet />  {/* Child routes yahan render honge */}
      </div>
    </div>
  );
}

export default ProductsLayout;

App with Nested Routes:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import ProductsLayout from './layouts/ProductsLayout';
import AllProducts from './pages/AllProducts';
import Electronics from './pages/Electronics';
import Clothing from './pages/Clothing';
import Books from './pages/Books';

function App() {
  return (
    <Routes>
      <Route path="/products" element={<ProductsLayout />}>
        <Route path="all" element={<AllProducts />} />
        <Route path="electronics" element={<Electronics />} />
        <Route path="clothing" element={<Clothing />} />
        <Route path="books" element={<Books />} />
        
        {/* Default nested route – /products par */}
        <Route index element={<AllProducts />} />
      </Route>
    </Routes>
  );
}

URL Mapping:

URLComponent Rendered
/productsProductsLayout + AllProducts (index)
/products/allProductsLayout + AllProducts
/products/electronicsProductsLayout + Electronics
/products/clothingProductsLayout + Clothing
/products/booksProductsLayout + Books

7. Dynamic Routes – URL Parameters

Dynamic Routes – jab URL mein variable data ho (jaise /user/123, /product/101)

Dynamic Route Definition:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import ProductDetail from './pages/ProductDetail';
import UserProfile from './pages/UserProfile';

function App() {
  return (
    <Routes>
      {/* Dynamic route – :id parameter */}
      <Route path="/product/:id" element={<ProductDetail />} />
      
      {/* Multiple parameters */}
      <Route path="/user/:userId/post/:postId" element={<UserPost />} />
      
      {/* Optional parameter – ? means optional */}
      <Route path="/profile/:username?" element={<Profile />} />
    </Routes>
  );
}

useParams Hook – Parameters Access Karna:

Code
// src/pages/ProductDetail.jsx
import { useParams } from 'react-router-dom';
import { useState, useEffect } from 'react';

function ProductDetail() {
  const { id } = useParams();  // Extract id from URL
  const [product, setProduct] = useState(null);
  const [loading, setLoading] = useState(true);
  
  useEffect(() => {
    // Fetch product using the id
    fetch(`/api/products/${id}`)
      .then(res => res.json())
      .then(data => {
        setProduct(data);
        setLoading(false);
      });
  }, [id]);  // Re-fetch when id changes
  
  if (loading) return <div>Loading product...</div>;
  
  return (
    <div>
      <h1>{product?.name}</h1>
      <p>Price: ${product?.price}</p>
      <p>Description: {product?.description}</p>
    </div>
  );
}

export default ProductDetail;

Multiple Parameters Example:

Code
// src/pages/UserPost.jsx
import { useParams } from 'react-router-dom';

function UserPost() {
  const { userId, postId } = useParams();
  
  return (
    <div>
      <h2>User ID: {userId}</h2>
      <h3>Post ID: {postId}</h3>
      <p>Showing post {postId} by user {userId}</p>
    </div>
  );
}
Code
// src/components/ProductCard.jsx
import { Link } from 'react-router-dom';

function ProductCard({ product }) {
  return (
    <div className="product-card">
      <h3>{product.name}</h3>
      <p>${product.price}</p>
      <Link to={`/product/${product.id}`}>
        View Details
      </Link>
    </div>
  );
}

8. useNavigate Hook – Programmatic Navigation

useNavigate – button click, form submit, ya logic ke baad navigation के लिए।

Code
// src/pages/Login.jsx
import { useState } from 'react';
import { useNavigate } from 'react-router-dom';

function Login() {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const navigate = useNavigate();  // ✅ Get navigate function
  
  const handleLogin = async (e) => {
    e.preventDefault();
    
    // API call for login
    const response = await fetch('/api/login', {
      method: 'POST',
      body: JSON.stringify({ email, password })
    });
    
    if (response.ok) {
      // ✅ Navigate to dashboard after successful login
      navigate('/dashboard');
    } else {
      alert('Login failed!');
    }
  };
  
  return (
    <form onSubmit={handleLogin}>
      <input 
        type="email"
        value={email}
        onChange={(e) => setEmail(e.target.value)}
        placeholder="Email"
      />
      <input 
        type="password"
        value={password}
        onChange={(e) => setPassword(e.target.value)}
        placeholder="Password"
      />
      <button type="submit">Login</button>
    </form>
  );
}
Code
function NavigationExample() {
  const navigate = useNavigate();
  
  // 1. Simple navigation
  const goToHome = () => navigate('/');
  
  // 2. Go back (previous page)
  const goBack = () => navigate(-1);
  
  // 3. Go forward
  const goForward = () => navigate(1);
  
  // 4. Replace current history (back button se wapas na aaye)
  const replacePage = () => navigate('/new-page', { replace: true });
  
  // 5. With state (data pass karna)
  const goWithState = () => {
    navigate('/dashboard', { 
      state: { from: 'login', userId: 123 } 
    });
  };
  
  return (
    <div>
      <button onClick={goToHome}>Home</button>
      <button onClick={goBack}>Back</button>
      <button onClick={goForward}>Forward</button>
    </div>
  );
}

Receiving State on Other Page:

Code
// src/pages/Dashboard.jsx
import { useLocation } from 'react-router-dom';

function Dashboard() {
  const location = useLocation();
  const state = location.state;  // { from: 'login', userId: 123 }
  
  return (
    <div>
      <h2>Dashboard</h2>
      {state && <p>You came from: {state.from}</p>}
    </div>
  );
}

9. useParams Hook – URL Parameters Access Karna

(Dynamic Routes section mein already cover ho gaya – but additional tips)

Code
// src/pages/SearchResults.jsx
import { useParams, useLocation } from 'react-router-dom';

function SearchResults() {
  const { query } = useParams();  // URL se parameter
  const location = useLocation(); // Query parameters ke liye
  const searchParams = new URLSearchParams(location.search);
  const page = searchParams.get('page');  // ?page=2
  
  return (
    <div>
      <h2>Search Results for: {query}</h2>
      <p>Page: {page || 1}</p>
    </div>
  );
}

10. Protected Routes – Authentication Guard

Protected Route – sirf logged-in users ko page dikhana।

ProtectedRoute Component:

Code
// src/components/ProtectedRoute.jsx
import { Navigate } from 'react-router-dom';

function ProtectedRoute({ children }) {
  const isLoggedIn = localStorage.getItem('token'); // Check authentication
  
  if (!isLoggedIn) {
    // Not logged in – redirect to login
    return <Navigate to="/login" replace />;
  }
  
  // Logged in – show the page
  return children;
}

export default ProtectedRoute;

Using ProtectedRoute:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import ProtectedRoute from './components/ProtectedRoute';
import Dashboard from './pages/Dashboard';
import Profile from './pages/Profile';
import Settings from './pages/Settings';
import Login from './pages/Login';

function App() {
  return (
    <Routes>
      {/* Public routes */}
      <Route path="/login" element={<Login />} />
      <Route path="/" element={<Home />} />
      
      {/* Protected routes */}
      <Route path="/dashboard" element={
        <ProtectedRoute>
          <Dashboard />
        </ProtectedRoute>
      } />
      
      <Route path="/profile" element={
        <ProtectedRoute>
          <Profile />
        </ProtectedRoute>
      } />
      
      <Route path="/settings" element={
        <ProtectedRoute>
          <Settings />
        </ProtectedRoute>
      } />
    </Routes>
  );
}

Advanced Protected Route with Role-Based Access:

Code
// src/components/RoleBasedRoute.jsx
import { Navigate } from 'react-router-dom';

function RoleBasedRoute({ children, allowedRoles }) {
  const user = JSON.parse(localStorage.getItem('user'));
  
  if (!user) {
    return <Navigate to="/login" replace />;
  }
  
  if (!allowedRoles.includes(user.role)) {
    return <Navigate to="/unauthorized" replace />;
  }
  
  return children;
}

// Usage
<Route path="/admin" element={
  <RoleBasedRoute allowedRoles={['admin']}>
    <AdminDashboard />
  </RoleBasedRoute>
} />

<Route path="/moderator" element={
  <RoleBasedRoute allowedRoles={['admin', 'moderator']}>
    <ModeratorPanel />
  </RoleBasedRoute>
} />

11. 404 Page – Not Found Route

404 Page – jab koi matching route na mile।

Code
// src/pages/NotFound.jsx
import { Link } from 'react-router-dom';

function NotFound() {
  return (
    <div style={{ textAlign: 'center', marginTop: '50px' }}>
      <h1>404</h1>
      <h2>Page Not Found</h2>
      <p>Sorry, the page you are looking for does not exist.</p>
      <Link to="/">Go Back to Home</Link>
    </div>
  );
}

export default NotFound;

Catch-All Route:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import NotFound from './pages/NotFound';

function App() {
  return (
    <Routes>
      <Route path="/" element={<Home />} />
      <Route path="/about" element={<About />} />
      <Route path="/products" element={<Products />} />
      
      {/* Catch-all route – must be LAST */}
      <Route path="*" element={<NotFound />} />
    </Routes>
  );
}

12. Real-world Project – Complete E-commerce Routing

Complete App Structure:

Code
// src/App.jsx
import { Routes, Route } from 'react-router-dom';
import Layout from './components/Layout';
import ProtectedRoute from './components/ProtectedRoute';
import Home from './pages/Home';
import Products from './pages/Products';
import ProductDetail from './pages/ProductDetail';
import Cart from './pages/Cart';
import Checkout from './pages/Checkout';
import Login from './pages/Login';
import Register from './pages/Register';
import Dashboard from './pages/Dashboard';
import Orders from './pages/Orders';
import Profile from './pages/Profile';
import NotFound from './pages/NotFound';

function App() {
  return (
    <Routes>
      <Route path="/" element={<Layout />}>
        {/* Public routes */}
        <Route index element={<Home />} />
        <Route path="products" element={<Products />} />
        <Route path="product/:id" element={<ProductDetail />} />
        <Route path="cart" element={<Cart />} />
        <Route path="login" element={<Login />} />
        <Route path="register" element={<Register />} />
        
        {/* Protected routes (require login) */}
        <Route path="checkout" element={
          <ProtectedRoute>
            <Checkout />
          </ProtectedRoute>
        } />
        
        <Route path="dashboard" element={
          <ProtectedRoute>
            <Dashboard />
          </ProtectedRoute>
        } />
        
        <Route path="orders" element={
          <ProtectedRoute>
            <Orders />
          </ProtectedRoute>
        } />
        
        <Route path="profile" element={
          <ProtectedRoute>
            <Profile />
          </ProtectedRoute>
        } />
        
        {/* 404 catch-all */}
        <Route path="*" element={<NotFound />} />
      </Route>
    </Routes>
  );
}

export default App;
Code
// src/components/Layout.jsx
import { Outlet } from 'react-router-dom';
import Navbar from './Navbar';
import Footer from './Footer';

function Layout() {
  return (
    <div className="app-layout">
      <Navbar />
      <main className="main-content">
        <Outlet />
      </main>
      <Footer />
    </div>
  );
}

export default Layout;
Code
// src/components/Navbar.jsx
import { Link, NavLink } from 'react-router-dom';
import { useContext } from 'react';
import { CartContext } from '../contexts/CartContext';

function Navbar() {
  const { cartCount } = useContext(CartContext);
  const isLoggedIn = localStorage.getItem('token');
  
  return (
    <nav className="navbar">
      <Link to="/" className="logo">ShopEasy</Link>
      
      <div className="nav-links">
        <NavLink to="/">Home</NavLink>
        <NavLink to="/products">Products</NavLink>
        <NavLink to="/cart">
          Cart {cartCount > 0 && <span className="cart-badge">{cartCount}</span>}
        </NavLink>
        
        {isLoggedIn ? (
          <>
            <NavLink to="/dashboard">Dashboard</NavLink>
            <button onClick={handleLogout}>Logout</button>
          </>
        ) : (
          <>
            <NavLink to="/login">Login</NavLink>
            <NavLink to="/register">Register</NavLink>
          </>
        )}
      </div>
    </nav>
  );
}

13. Common Mistakes + Solutions

Mistake 1: Forgetting to wrap App with BrowserRouter

Code
// ❌ Error: useRoutes() may be used only in the context of a <Router> component
ReactDOM.render(<App />, document.getElementById('root'));

// ✅ Correct
ReactDOM.render(
  <BrowserRouter>
    <App />
  </BrowserRouter>,
  document.getElementById('root')
);

Mistake 2: Using <a> instead of <Link>

Code
// ❌ Page reload hoga – SPA advantage khatam
<a href="/products">Products</a>

// ✅ No reload – smooth navigation
<Link to="/products">Products</Link>

Mistake 3: Routes order – Catch-all route beech mein

Code
// ❌ Catch-all route pehle – baaki routes kabhi match nahi honge
<Routes>
  <Route path="*" element={<NotFound />} />
  <Route path="/products" element={<Products />} />
</Routes>

// ✅ Catch-all route LAST mein
<Routes>
  <Route path="/products" element={<Products />} />
  <Route path="*" element={<NotFound />} />
</Routes>

Mistake 4: Nested routes mein element bhoolna

Code
// ❌ Missing element prop on parent
<Route path="/products">
  <Route path="all" element={<AllProducts />} />
</Route>

// ✅ Parent route needs element (with Outlet)
<Route path="/products" element={<ProductsLayout />}>
  <Route path="all" element={<AllProducts />} />
</Route>

Mistake 5: useNavigate outside Router context

Code
// ❌ Error: useNavigate() may be used only in context of Router
function MyComponent() {
  const navigate = useNavigate(); // Error if not inside Router
}

// ✅ Make sure component is inside BrowserRouter

15. FAQ

Q1: React Router v6 Routing Hindi में सबसे important change kya hai v5 se?
Switch → Routes, useHistory → useNavigate, exact prop ki zaroorat nahi (v6 exact by default hai)

Q2: Link aur NavLink mein kya antar hai?
NavLink active state deta hai (styling ke liye), Link sirf navigation करता है।

Q3: Nested Routes kyun use karein?
Common layout (header, sidebar, footer) share karne ke liye – code duplicate nahi karna padta।

Q4: Dynamic routes mein multiple parameters kaise handle karein?
/user/:userId/post/:postId – useParams se dono mil jayenge: { userId, postId }

Q5: Protected Route kaise banayein?
Component banayein jo authentication check kare – agar logged in nahi toh <Navigate to="/login" />

Q6: useNavigate vs <Link> – kab kya use karein?
<Link> – JSX mein direct navigation के लिए। useNavigate – button click, form submit, ya logic ke baad navigation के लिए।

Q7: 404 page kaise implement karein?
Last route mein <Route path="*" element={<NotFound />} /> add karo।

Q8: URL se query parameters (?page=2&sort=asc) kaise read karein?
useLocation() hook + new URLSearchParams(location.search)

Q9: Kya React Router v6 TypeScript ke saath kaam karta hai?
Haan, full TypeScript support hai – useParams<{ id: string }>()

Q10: React Router v6 mein lazy loading kaise karein?
React.lazy() + Suspense with Route: <Route path="/about" element={<Suspense fallback={<div>Loading...</div>}><About /></Suspense>} />

16. Conclusion

बहुत बढ़िया दोस्तों! आज हमने React Router v6 Routing Hindi को पूरी detail में समझा।

Quick Recap:

ConceptKey Takeaway
BrowserRouterApp ko Router provide karna
Routes + RoutePages define karna
Link / NavLinkNavigation without reload
Nested RoutesLayouts ke saath child pages
Dynamic RoutesURL parameters (/user/:id)
useNavigateProgrammatic navigation
Protected RoutesAuthentication guard

Mera personal experience:

जब मैंने पहली बार React Router सीखा, तो v5 use karta tha – Switch, exact, useHistory – thoda confusing था। v6 ने bohot simplify kar diya। अब Routes और useNavigate – code bohot cleaner है।

Tum bhi ye project zaroor karo:

  1. ✅ E-commerce website routing
  2. ✅ Blog with nested routes (categories)
  3. ✅ Dashboard with protected routes
  4. ✅ Multi-step form with navigation

अब तुम्हारी बारी है!

नीचे comment में बताओ:

  1. तुम्हें nested routes easy lage ya dynamic routes?
  2. क्या तुमने कभी protected route implement kiya hai?
  3. अगला topic क्या चाहिए? (Context API? Redux? Tailwind CSS?)

The Easy Master पर बने रहो। Happy Routing! ⚛️🚀
