Example 1: Now write down the following code in the App.js file. Here, we have shown the Navbar component with the expand property.

Javascript

import React from 'react'
import 'bootstrap/dist/css/bootstrap.min.css';
import {
    Navbar,
    NavItem,
    NavbarToggler,
    Collapse,
    NavLink,
    Nav,
    NavbarBrand
} from 'reactstrap';

function App() {

    // Collapse isOpen State
    const [isOpen, setIsOpen] = React.useState(false);

    return (
        <div style={{
            display: 'block', width: 550, padding: 30
        }}>
            <h5>ReactJS Reactstrap Navbar Component</h5>
            <Navbar color="light" light expand="md">
                <NavbarBrand href="/">Brand</NavbarBrand>
                <NavbarToggler onClick={() => { setIsOpen(!isOpen) }} />
                <Collapse isOpen={isOpen} navbar>
                    <Nav className="mr-auto" navbar>
                        <NavItem>
                            <NavLink href="#">Home</NavLink>
                        </NavItem>
                        <NavItem>
                            <NavLink href="#">Login</NavLink>
                        </NavItem>
                        <NavItem>
                            <NavLink href="#">Signup</NavLink>
                        </NavItem>
                    </Nav>
                </Collapse>
            </Navbar>
        </div >
    );
}

export default App;

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:

Example 2: Now write down the following code in the App.js file. Here, we have shown the Navbar component without the expand property.

Javascript

import React from 'react'
import 'bootstrap/dist/css/bootstrap.min.css';
import {
    Navbar,
    NavItem,
    NavbarToggler,
    Collapse,
    NavLink,
    Nav,
    NavbarBrand
} from 'reactstrap';

function App() {

    // Collapse isOpen State
    const [isOpen, setIsOpen] = React.useState(false);

    return (
        <div style={{
            display: 'block', width: 550, padding: 30
        }}>
            <h5>ReactJS Reactstrap Navbar Component</h5>
            <Navbar color="light" light >
                <NavbarBrand href="/">Brand</NavbarBrand>
                <NavbarToggler onClick={() => { setIsOpen(!isOpen) }} />
                <Collapse isOpen={isOpen} navbar>
                    <Nav className="mr-auto" navbar>
                        <NavItem>
                            <NavLink href="#">Home</NavLink>

                </Collapse>
            </Navbar>
        </div >
    );
}

export default App;
