How to Create Bootstrap Navbar in React.js - Developer Guide

Building a responsive navigation bar is essential for modern web applications. Combining Bootstrap’s proven navbar component with React.js creates powerful, interactive navigation that scales beautifully across all devices. This comprehensive guide will teach you how to implement Bootstrap navbar React.js solutions, from basic setup to advanced state management and custom hooks.

Why Use Bootstrap Navbar with React.js?

Bootstrap navbar React.js integration offers the best of both worlds: Bootstrap’s battle-tested responsive design patterns and React’s component-based architecture. This combination provides developers with reusable, maintainable navigation components that handle complex state management while maintaining Bootstrap’s accessibility standards.

React.js brings dynamic functionality to Bootstrap navbars, enabling features like active link highlighting based on routing, conditional rendering of menu items, and real-time updates without page refreshes. Meanwhile, Bootstrap ensures your navbar works consistently across browsers and devices with minimal custom CSS.

Prerequisites and Project Setup

Before implementing Bootstrap navbar React.js components, ensure you have a solid foundation with the necessary dependencies and project structure.

Required Dependencies

First, create a new React application and install the required packages:

# Create new React app
npx create-react-app bootstrap-navbar-app
cd bootstrap-navbar-app

# Install Bootstrap and React Bootstrap
npm install bootstrap react-bootstrap

# For routing functionality
npm install react-router-dom

# Optional: For icons
npm install react-icons

Initial Configuration

Configure Bootstrap in your React application by importing the CSS in your src/index.js or src/App.js:

// src/index.js
import React from 'react';
import ReactDOM from 'react-dom/client';
import 'bootstrap/dist/css/bootstrap.min.css';
import App from './App';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<App />);

This setup ensures Bootstrap’s CSS is available throughout your React application, providing the foundation for your Bootstrap navbar React.js components.

Basic Bootstrap Navbar React.js Implementation

Let’s start with a fundamental Bootstrap navbar React.js component that demonstrates the core structure and functionality:

// components/BasicNavbar.js
import React from 'react';
import { Navbar, Nav, Container } from 'react-bootstrap';

function BasicNavbar() {
  return (
    <Navbar bg="light" expand="lg" className="shadow-sm">
      <Container>
        <Navbar.Brand href="#home">
          <strong>React App</strong>
        </Navbar.Brand>
        
        <Navbar.Toggle aria-controls="basic-navbar-nav" />
        
        <Navbar.Collapse id="basic-navbar-nav">
          <Nav className="me-auto">
            <Nav.Link href="#home">Home</Nav.Link>
            <Nav.Link href="#about">About</Nav.Link>
            <Nav.Link href="#services">Services</Nav.Link>
            <Nav.Link href="#contact">Contact</Nav.Link>
          </Nav>
        </Navbar.Collapse>
      </Container>
    </Navbar>
  );
}

export default BasicNavbar;

This Bootstrap navbar React.js component uses React Bootstrap components that automatically handle responsive behavior, accessibility attributes, and mobile menu functionality. The expand="lg" prop controls when the navbar collapses, while Navbar.Toggle and Navbar.Collapse manage the mobile menu state.

Integrating React Router for Navigation

Real-world Bootstrap navbar React.js implementations require proper routing. React Router provides seamless navigation without page refreshes:

// components/RouterNavbar.js
import React from 'react';
import { Navbar, Nav, Container } from 'react-bootstrap';
import { LinkContainer } from 'react-router-bootstrap';
import { useLocation } from 'react-router-dom';

function RouterNavbar() {
  const location = useLocation();

  return (
    <Navbar bg="dark" variant="dark" expand="lg" sticky="top">
      <Container>
        <LinkContainer to="/">
          <Navbar.Brand>
            <strong>MyApp</strong>
          </Navbar.Brand>
        </LinkContainer>
        
        <Navbar.Toggle aria-controls="router-navbar-nav" />
        
        <Navbar.Collapse id="router-navbar-nav">
          <Nav className="me-auto">
            <LinkContainer to="/">
              <Nav.Link active={location.pathname === '/'}>
                Home
              </Nav.Link>
            </LinkContainer>
            
            <LinkContainer to="/about">
              <Nav.Link active={location.pathname === '/about'}>
                About
              </Nav.Link>
            </LinkContainer>
            
            <LinkContainer to="/products">
              <Nav.Link active={location.pathname === '/products'}>
                Products
              </Nav.Link>
            </LinkContainer>
            
            <LinkContainer to="/contact">
              <Nav.Link active={location.pathname === '/contact'}>
                Contact
              </Nav.Link>
            </LinkContainer>
          </Nav>
        </Navbar.Collapse>
      </Container>
    </Navbar>
  );
}

export default RouterNavbar;

Setting Up the Router

Configure your main App component to use React Router:

// App.js
import React from 'react';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';
import RouterNavbar from './components/RouterNavbar';
import Home from './pages/Home';
import About from './pages/About';
import Products from './pages/Products';
import Contact from './pages/Contact';

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

export default App;

This Bootstrap navbar React.js setup with routing provides active link highlighting and seamless navigation between components.

Advanced Dropdown Menus with State Management

Bootstrap navbar React.js components can include sophisticated dropdown menus with dynamic content and state management:

// components/AdvancedNavbar.js
import React, { useState, useEffect } from 'react';
import { Navbar, Nav, NavDropdown, Container, Badge } from 'react-bootstrap';
import { LinkContainer } from 'react-router-bootstrap';
import { FaShoppingCart, FaUser, FaBell } from 'react-icons/fa';

function AdvancedNavbar({ user, cartItems, notifications }) {
  const [show, setShow] = useState(false);
  const [cartCount, setCartCount] = useState(0);

  useEffect(() => {
    setCartCount(cartItems?.length || 0);
  }, [cartItems]);

  const handleLogout = () => {
    // Logout logic here
    console.log('Logging out...');
  };

  return (
    <Navbar bg="white" expand="lg" className="shadow-sm border-bottom">
      <Container>
        <LinkContainer to="/">
          <Navbar.Brand className="fw-bold text-primary">
            <span className="fs-3">ShopReact</span>
          </Navbar.Brand>
        </LinkContainer>
        
        <Navbar.Toggle aria-controls="advanced-navbar-nav" />
        
        <Navbar.Collapse id="advanced-navbar-nav">
          <Nav className="me-auto">
            <LinkContainer to="/">
              <Nav.Link>Home</Nav.Link>
            </LinkContainer>
            
            <NavDropdown title="Categories" id="categories-dropdown">
              <LinkContainer to="/electronics">
                <NavDropdown.Item>Electronics</NavDropdown.Item>
              </LinkContainer>
              <LinkContainer to="/clothing">
                <NavDropdown.Item>Clothing</NavDropdown.Item>
              </LinkContainer>
              <LinkContainer to="/books">
                <NavDropdown.Item>Books</NavDropdown.Item>
              </LinkContainer>
              <NavDropdown.Divider />
              <LinkContainer to="/sale">
                <NavDropdown.Item className="text-danger fw-bold">
                  Sale Items
                </NavDropdown.Item>
              </LinkContainer>
            </NavDropdown>
            
            <LinkContainer to="/about">
              <Nav.Link>About</Nav.Link>
            </LinkContainer>
          </Nav>
          
          {/* Right-aligned items */}
          <Nav>
            {/* Notifications */}
            <NavDropdown

                  )}
                </span>
              }
              id="notifications-dropdown"
              align="end"
            >
              {notifications?.length > 0 ? (
                notifications.map((notification, index) => (

                  No notifications
                </NavDropdown.Item>
              )}
            </NavDropdown>
            
            {/* Shopping Cart */}
            <LinkContainer to="/cart">

        </Navbar.Collapse>
      </Container>
    </Navbar>
  );
}

export default AdvancedNavbar;

This advanced Bootstrap navbar React.js component demonstrates real-world features like user authentication states, shopping cart counters, and notification badges with dynamic updates.

Creating Reusable Navbar Hooks

Custom hooks make Bootstrap navbar React.js components more maintainable and reusable across your application:

// hooks/useNavbar.js
import { useState, useEffect } from 'react';
import { useLocation } from 'react-router-dom';

export const useNavbar = () => {
  const [isExpanded, setIsExpanded] = useState(false);
  const [scrolled, setScrolled] = useState(false);
  const location = useLocation();

  // Close mobile menu when route changes
  useEffect(() => {
    setIsExpanded(false);
  }, [location]);

  // Handle scroll effects
  useEffect(() => {
    const handleScroll = () => {
      const isScrolled = window.scrollY > 10;
      setScrolled(isScrolled);
    };

    window.addEventListener('scroll', handleScroll);
    return () => window.removeEventListener('scroll', handleScroll);
  }, []);

  const toggleNavbar = () => {
    setIsExpanded(!isExpanded);
  };

  const closeNavbar = () => {
    setIsExpanded(false);
  };

  return {
    isExpanded,
    scrolled,
    toggleNavbar,
    closeNavbar,
    currentPath: location.pathname
  };
};

// hooks/useAuth.js
import { useState, useEffect } from 'react';

export const useAuth = () => {
  const [user, setUser] = useState(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    // Simulate auth check
    const checkAuth = async () => {
      try {
        // Replace with actual auth logic
        const userData = localStorage.getItem('user');
        if (userData) {
          setUser(JSON.parse(userData));
        }
      } catch (error) {
        console.error('Auth check failed:', error);
      } finally {
        setLoading(false);
      }
    };

    checkAuth();
  }, []);

  const login = async (credentials) => {
    // Login logic
    setLoading(true);
    try {
      // Replace with actual login API call
      const userData = { name: credentials.username, email: credentials.email };
      localStorage.setItem('user', JSON.stringify(userData));
      setUser(userData);
      return { success: true };
    } catch (error) {
      return { success: false, error: error.message };
    } finally {
      setLoading(false);
    }
  };

  const logout = () => {
    localStorage.removeItem('user');
    setUser(null);
  };

  return { user, loading, login, logout };
};

Smart Navbar Component with Custom Hooks

Combine custom hooks to create an intelligent Bootstrap navbar React.js component:

// components/SmartNavbar.js
import React from 'react';
import { Navbar, Nav, NavDropdown, Container } from 'react-bootstrap';
import { LinkContainer } from 'react-router-bootstrap';
import { useNavbar } from '../hooks/useNavbar';
import { useAuth } from '../hooks/useAuth';
import { FaHome, FaInfoCircle, FaCog, FaSignOutAlt } from 'react-icons/fa';

function SmartNavbar() {
  const { isExpanded, scrolled, toggleNavbar, currentPath } = useNavbar();
  const { user, logout } = useAuth();

  const navbarClass = `${scrolled ? 'shadow' : ''} transition-all`;

  const isActive = (path) => currentPath === path;

  return (
    <Navbar 
      bg={scrolled ? 'white' : 'light'} 
      expand="lg" 
      fixed="top"
      expanded={isExpanded}
      onToggle={toggleNavbar}
      className={navbarClass}
    >
      <Container>
        <LinkContainer to="/">
          <Navbar.Brand className="fw-bold">
            SmartApp
          </Navbar.Brand>
        </LinkContainer>
        
        <Navbar.Toggle aria-controls="smart-navbar-nav" />
        
        <Navbar.Collapse id="smart-navbar-nav">
          <Nav className="me-auto">
            <LinkContainer to="/">
              <Nav.Link active={isActive('/')}>
                <FaHome className="me-1" />
                Home
              </Nav.Link>
            </LinkContainer>
            
            <LinkContainer to="/about">
              <Nav.Link active={isActive('/about')}>
                <FaInfoCircle className="me-1" />
                About
              </Nav.Link>
            </LinkContainer>
            
            <NavDropdown title="Services" id="services-dropdown">
              <LinkContainer to="/web-development">
                <NavDropdown.Item>Web Development</NavDropdown.Item>
              </LinkContainer>
              <LinkContainer to="/mobile-apps">
                <NavDropdown.Item>Mobile Apps</NavDropdown.Item>
              </LinkContainer>
              <LinkContainer to="/consulting">
                <NavDropdown.Item>Consulting</NavDropdown.Item>
              </LinkContainer>
            </NavDropdown>
          </Nav>
          
          <Nav>
            {user ? (
              <NavDropdown 
                title={`Welcome, ${user.name}`} 
                id="user-dropdown"
                align="end"
              >
                <LinkContainer to="/dashboard">
                  <NavDropdown.Item>Dashboard</NavDropdown.Item>
                </LinkContainer>
                <LinkContainer to="/settings">
                  <NavDropdown.Item>
                    <FaCog className="me-1" />
                    Settings
                  </NavDropdown.Item>
                </LinkContainer>
                <NavDropdown.Divider />
                <NavDropdown.Item onClick={logout}>
                  <FaSignOutAlt className="me-1" />
                  Logout
                </NavDropdown.Item>
              </NavDropdown>
            ) : (
              <>
                <LinkContainer to="/login">
                  <Nav.Link>Login</Nav.Link>
                </LinkContainer>
                <LinkContainer to="/register">
                  <Nav.Link>Register</Nav.Link>
                </LinkContainer>
              </>
            )}
          </Nav>
        </Navbar.Collapse>
      </Container>
    </Navbar>
  );
}

export default SmartNavbar;

Responsive Design and Mobile Optimization

Bootstrap navbar React.js components require careful attention to mobile user experience. Here’s how to optimize for different screen sizes:

// components/ResponsiveNavbar.js
import React, { useState, useEffect } from 'react';
import { Navbar, Nav, Container, Offcanvas } from 'react-bootstrap';
import { LinkContainer } from 'react-router-bootstrap';

function ResponsiveNavbar() {
  const [showOffcanvas, setShowOffcanvas] = useState(false);
  const [isMobile, setIsMobile] = useState(window.innerWidth < 992);

  useEffect(() => {
    const handleResize = () => {
      setIsMobile(window.innerWidth < 992);
    };

    window.addEventListener('resize', handleResize);
    return () => window.removeEventListener('resize', handleResize);
  }, []);

  const handleClose = () => setShowOffcanvas(false);
  const handleShow = () => setShowOffcanvas(true);

  return (
    <>
      <Navbar bg="primary" variant="dark" expand="lg" className="px-3">
        <LinkContainer to="/">
          <Navbar.Brand>ResponsiveApp</Navbar.Brand>
        </LinkContainer>

Search Integration and Form Handling

Real-world Bootstrap navbar React.js implementations often include search functionality:

// components/SearchNavbar.js
import React, { useState, useRef, useEffect } from 'react';
import { 
  Navbar, 
  Nav, 
  Container, 
  Form, 
  FormControl, 
  Button,
  Dropdown,
  ListGroup 
} from 'react-bootstrap';
import { FaSearch, FaTimes } from 'react-icons/fa';

function SearchNavbar() {
  const [searchQuery, setSearchQuery] = useState('');
  const [searchResults, setSearchResults] = useState([]);
  const [showResults, setShowResults] = useState(false);
  const searchRef = useRef(null);

  // Mock search data
  const mockData = [
    'React Components',
    'Bootstrap Navbar',
    'JavaScript Hooks',
    'CSS Styling',
    'Responsive Design'
  ];

  useEffect(() => {
    const handleClickOutside = (event) => {
      if (searchRef.current && !searchRef.current.contains(event.target)) {
        setShowResults(false);
      }
    };

    document.addEventListener('mousedown', handleClickOutside);
    return () => document.removeEventListener('mousedown', handleClickOutside);
  }, []);

  const handleSearch = (query) => {
    setSearchQuery(query);
    
    if (query.length > 0) {
      const filtered = mockData.filter(item =>
        item.toLowerCase().includes(query.toLowerCase())
      );
      setSearchResults(filtered);
      setShowResults(true);
    } else {
      setSearchResults([]);
      setShowResults(false);
    }
  };

  const handleSearchSubmit = (e) => {

      console.log('Searching for:', searchQuery);
      setShowResults(false);

      </Container>
    </Navbar>
  );
}

Performance Optimization and Best Practices

Optimizing Bootstrap navbar React.js components for performance requires attention to rendering efficiency and bundle size:

Lazy Loading Components

// components/LazyNavbar.js
import React, { Suspense, lazy } from 'react';
import { Navbar, Container, Spinner } from 'react-bootstrap';

// Lazy load heavy components
const UserMenu = lazy(() => import('./UserMenu'));
const NotificationCenter = lazy(() => import('./NotificationCenter'));

function LazyNavbar({ user }) {
  return (
    <Navbar bg="light" expand="lg">
      <Container>
        <Navbar.Brand>OptimizedApp</Navbar.Brand>
        
        <div className="d-flex align-items-center">
          {user && (
            <Suspense fallback={<Spinner size="sm" />}>
              <NotificationCenter userId={user.id} />
              <UserMenu user={user} />
            </Suspense>
          )}
        </div>
      </Container>
    </Navbar>
  );
}

export default LazyNavbar;

Memoized Navbar Component

// components/MemoizedNavbar.js
import React, { memo } from 'react';
import { Navbar, Nav, Container } from 'react-bootstrap';

const MemoizedNavbar = memo(({ activeRoute, user, cartCount }) => {
  return (
    <Navbar bg="white" expand="lg" className="shadow-sm">
      <Container>
        <Navbar.Brand>MemoApp</Navbar.Brand>
        
        <Nav className="me-auto">
          <Nav.Link active={activeRoute === 'home'}>Home</Nav.Link>
          <Nav.Link active={activeRoute === 'products'}>Products</Nav.Link>
        </Nav>
        
        {user && (
          <Nav>
            <Nav.Link>
              Cart ({cartCount})
            </Nav.Link>
            <Nav.Link>{user.name}</Nav.Link>
          </Nav>
        )}
      </Container>
    </Navbar>
  );
});

export default MemoizedNavbar;

Testing Bootstrap Navbar React.js Components

Comprehensive testing ensures your Bootstrap navbar React.js components work reliably:

// __tests__/Navbar.test.js
import React from 'react';
import { render, screen, fireEvent } from '@testing-library/react';
import { BrowserRouter } from 'react-router-dom';
import '@testing-library/jest-dom';
import BasicNavbar from '../components/BasicNavbar';

const renderWithRouter = (component) => {
  return render(
    <BrowserRouter>
      {component}
    </BrowserRouter>
  );
};

describe('BasicNavbar', () => {
  test('renders navbar brand', () => {
    renderWithRouter(<BasicNavbar />);
    expect(screen.getByText('React App')).toBeInTheDocument();
  });

  test('renders navigation links', () => {
    renderWithRouter(<BasicNavbar />);
    expect(screen.getByText('Home')).toBeInTheDocument();
    expect(screen.getByText('About')).toBeInTheDocument();
    expect(screen.getByText('Services')).toBeInTheDocument();
    expect(screen.getByText('Contact')).toBeInTheDocument();
  });

  test('toggles mobile menu', () => {
    renderWithRouter(<BasicNavbar />);
    const toggleButton = screen.getByRole('button', { name: /toggle navigation/i });
    
    fireEvent.click(toggleButton);
    
    // Check if navbar is expanded
    expect(toggleButton).toHaveAttribute('aria-expanded', 'true');
  });

  test('is accessible', () => {
    renderWithRouter(<BasicNavbar />);
    const navbar = screen.getByRole('navigation');
    expect(navbar).toBeInTheDocument();
    
    const toggleButton = screen.getByRole('button', { name: /toggle navigation/i });
    expect(toggleButton).toHaveAttribute('aria-controls');
  });
});

Common Issues and Solutions

Mobile Menu Not Closing on Route Change

// Fixed with useEffect in custom hook
useEffect(() => {
  setIsExpanded(false);
}, [location]);

Bootstrap CSS Conflicts

// Use CSS Modules or styled-components for isolation
import styles from './Navbar.module.css';

<Navbar className={styles.customNavbar}>

Active Link Detection Issues

// Use React Router's useLocation hook
const location = useLocation();
const isActive = (path) => location.pathname === path;

Accessibility and SEO Considerations

Ensuring your Bootstrap navbar React.js components are accessible and SEO-friendly:

// components/AccessibleNavbar.js
import React from 'react';
import { Navbar, Nav, Container } from 'react-bootstrap';

function AccessibleNavbar() {
  return (
    <Navbar 
      bg="primary" 
      variant="dark" 
      expand="lg"
      role="navigation"
      aria-label="Main navigation"
    >
      <Container>
        <Navbar.Brand href="#home" aria-label="Company homepage">
          <span className="visually-hidden">Company Name - </span>
          Logo
        </Navbar.Brand>
        
        <Navbar.Toggle 
          aria-controls="accessible-navbar-nav"
          aria-label="Toggle navigation menu"
        />
        
        <Navbar.Collapse id="accessible-navbar-nav">
          <Nav className="me-auto" role="menubar">
            <Nav.Link 
              href="#home" 
              role="menuitem"
              aria-current="page"
            >
              Home
            </Nav.Link>
            <Nav.Link 
              href="#about" 
              role="menuitem"
            >
              About
            </Nav.Link>
          </Nav>
        </Navbar.Collapse>
      </Container>
    </Navbar>
  );
}

export default AccessibleNavbar;

SEO Best Practices

• Use semantic HTML elements
• Include proper heading hierarchy
• Add structured data for breadcrumbs
• Implement proper meta tags for each route

Real-World E-commerce Example

Here’s a comprehensive Bootstrap navbar React.js implementation for an e-commerce application:

// components/EcommerceNavbar.js
import React, { useState, useEffect } from 'react';

import { 
  FaSearch, 
  FaShoppingCart, 
  FaHeart, 
  FaUser, 
  FaBars,
  FaPhone,
  FaEnvelope 
} from 'react-icons/fa';

function EcommerceNavbar({ 
  user, 
  cartItems = [], 
  wishlistItems = [],
  categories = [],
  onSearch,
  onLogout 
}) {
  const [searchQuery, setSearchQuery] = useState('');
  const [showMobileMenu, setShowMobileMenu] = useState(false);
  const [scrolled, setScrolled] = useState(false);

  useEffect(() => {
    const handleScroll = () => {
      setScrolled(window.scrollY > 50);
    };

    window.addEventListener('scroll', handleScroll);
    return () => window.removeEventListener('scroll', handleScroll);
  }, []);

  const handleSearchSubmit = (e) => {
    e.preventDefault();
    if (searchQuery.trim() && onSearch) {
      onSearch(searchQuery.trim());
    }
  };

  const cartCount = cartItems.length;
  const wishlistCount = wishlistItems.length;

Context API Integration

For complex applications, integrate your Bootstrap navbar React.js components with React Context for global state management:

// context/AppContext.js
import React, { createContext, useContext, useReducer } from 'react';

const AppContext = createContext();

const initialState = {
  user: null,
  cart: [],
  wishlist: [],
  notifications: []
};

function appReducer(state, action) {
  switch (action.type) {
    case 'SET_USER':
      return { ...state, user: action.payload };
    case 'ADD_TO_CART':
      return { ...state, cart: [...state.cart, action.payload] };
    case 'REMOVE_FROM_CART':
      return { 
        ...state, 
        cart: state.cart.filter(item => item.id !== action.payload) 
      };
    case 'TOGGLE_WISHLIST':
      const existsInWishlist = state.wishlist.find(item => item.id === action.payload.id);
      if (existsInWishlist) {
        return {
          ...state,
          wishlist: state.wishlist.filter(item => item.id !== action.payload.id)
        };
      } else {
        return {
          ...state,
          wishlist: [...state.wishlist, action.payload]
        };
      }
    default:
      return state;
  }
}

export function AppProvider({ children }) {
  const [state, dispatch] = useReducer(appReducer, initialState);

  return (
    <AppContext.Provider value={{ state, dispatch }}>
      {children}
    </AppContext.Provider>
  );
}

export function useApp() {
  const context = useContext(AppContext);
  if (!context) {
    throw new Error('useApp must be used within AppProvider');
  }
  return context;
}

TypeScript Implementation

For TypeScript projects, here’s a type-safe Bootstrap navbar React.js implementation:

// types/navbar.ts
export interface User {
  id: string;
  name: string;
  email: string;
  avatar?: string;
}

export interface CartItem {
  id: string;
  name: string;
  price: number;
  quantity: number;
}

export interface Category {
  id: string;
  name: string;
  slug: string;
  subcategories?: Category[];
}

export interface NavbarProps {
  user?: User | null;
  cartItems?: CartItem[];
  categories?: Category[];
  onSearch?: (query: string) => void;
  onLogout?: () => void;
}

typescript

// components/TypedNavbar.tsx
import React, { useState, useCallback } from 'react';
import { Navbar, Nav, Container, Badge } from 'react-bootstrap';
import { LinkContainer } from 'react-router-bootstrap';
import { NavbarProps } from '../types/navbar';

const TypedNavbar: React.FC<NavbarProps> = ({
  user,
  cartItems = [],
  categories = [],
  onSearch,
  onLogout
}) => {
  const [searchQuery, setSearchQuery] = useState<string>('');

  const handleSearchSubmit = useCallback((e: React.FormEvent) => {
    e.preventDefault();
    if (searchQuery.trim() && onSearch) {
      onSearch(searchQuery.trim());
    }
  }, [searchQuery, onSearch]);

  const cartCount: number = cartItems.length;

  return (
    <Navbar bg="light" expand="lg" className="shadow-sm">
      <Container>
        <LinkContainer to="/">
          <Navbar.Brand className="fw-bold">
            TypedApp
          </Navbar.Brand>
        </LinkContainer>
        
        <Navbar.Toggle aria-controls="typed-navbar-nav" />
        
        <Navbar.Collapse id="typed-navbar-nav">
          <Nav className="me-auto">
            {categories.map((category) => (
              <LinkContainer key={category.id} to={`/category/${category.slug}`}>
                <Nav.Link>{category.name}</Nav.Link>
              </LinkContainer>
            ))}
          </Nav>
          
          <Nav>
            <LinkContainer to="/cart">
              <Nav.Link className="position-relative">
                Cart
                {cartCount > 0 && (
                  <Badge bg="primary" pill className="ms-1">
                    {cartCount}
                  </Badge>
                )}
              </Nav.Link>
            </LinkContainer>
            
            {user ? (
              <Nav.Link onClick={onLogout}>
                Logout ({user.name})
              </Nav.Link>
            ) : (
              <LinkContainer to="/login">
                <Nav.Link>Login</Nav.Link>
              </LinkContainer>
            )}
          </Nav>
        </Navbar.Collapse>
      </Container>
    </Navbar>
  );
};

export default TypedNavbar;

Deployment and Production Considerations

When deploying Bootstrap navbar React.js applications to production:

Build Optimization

// webpack.config.js modifications for production
module.exports = {
  optimization: {
    splitChunks: {
      chunks: 'all',
      cacheGroups: {
        bootstrap: {
          test: /[\\/]node_modules[\\/](bootstrap|react-bootstrap)[\\/]/,
          name: 'bootstrap',
          chunks: 'all',
        },
      },
    },
  },
};

Environment Configuration

// config/environment.js
const config = {
  development: {
    API_URL: 'http://localhost:3001',
    ENABLE_SEARCH_SUGGESTIONS: true
  },
  production: {
    API_URL: 'https://api.yoursite.com',
    ENABLE_SEARCH_SUGGESTIONS: false
  }
};

export default config[process.env.NODE_ENV || 'development'];
