Introduction:<\/strong>
Session Implementation is essential for managing user authentication and preserving user-specific data in React applications. It allows the application to keep track of a user’s login status, ensuring it can provide personalized experiences and secure access to authorized users.<\/p>\n\n\n\n

Local storage for session management:<\/strong>
Use the localstorage.setItem and localstorage.getItem functions to store and retrieve the isLoggedIn state.
const[isLoggedIn,setIsLoggedIn]=useState(localStorage.getItem(‘isLoggedIn’) ===’true’);<\/p>\n\n\n\n

Initialize isLoggedIn State:<\/strong><\/p>\n\n\n\n

Initialize the isLoggedIn state using the value retrieved from local storage. Update the state when the User logs in or logs out.

Redirect on login:<\/strong><\/p>\n\n\n\n

Implement handleLoginSuccess function, to set the isLoggedIn state to true when a user successfully logs in. Redirect the User to the dashboard upon successful login<\/p>\n\n\n\n

<\/p>\n\n\n\n

const handleLognSuccess = () =>{
setIsLoggedIn(true); <\/p>\n\n\n\n

localstorage.setItem(‘isLoggedIn’,’true’);<\/p>\n\n\n\n

history.push(‘\/dashboard’);
};<\/p>\n\n\n\n

Note: make sure to call the handleLoginSuccess function in the Login API Response upon successful login.<\/p>\n\n\n\n

Logout functionality:<\/strong><\/p>\n\n\n\n

Create handleLogout function to set the isLoggedIn state to false when the user logs out. clear the local storage to remove session data.<\/p>\n\n\n\n

Redirect the user to the login page after logging out.<\/p>\n\n\n\n

const handleLogout = () =>{
setIsLoggedIn(false);
\/\/clear session data from local storage<\/p>\n\n\n\n

localstorage.removeItem(‘isLoggedIn’);<\/p>\n\n\n\n

\/\/Redirect to login page<\/p>\n\n\n\n

history.push(‘\/’);<\/p>\n\n\n\n

};<\/p>\n\n\n\n

Conditional Rendering:<\/strong><\/p>\n\n\n\n

conditionally render Navbar and Sidenav based on the isLoggedIn state.show navigation menus and user-specific content when the user is logged in.<\/p>\n\n\n\n

{isLoggedIn && (<\/p>\n\n\n\n

<>
<Navbar handleDraweropen={handleDraweropen} handleLogout={handleLogout} \/><\/p>\n\n\n\n

<Sidenav mobileopen={mobileopen} handleDraweropen={handleDraweropen} handleDrawerClose={handleDrawerClose} isLoggedIn={isLoggedIn} handleLogout={handleLogout} \/>
<\/><\/p>\n\n\n\n

)}<\/p>\n\n\n\n


Protecting Routes:<\/strong><\/p>\n\n\n\n

Implement a PrivateRoute component to protect specific routes for authenticated users. Use React Router to ensure that only authenticated users can access certain pages.<\/p>\n\n\n\n

import { Route, Redirect } from ‘react-router-dom’;<\/p>\n\n\n\n

function PrivateRoute({ component: Component, isLoggedIn, \u2026rest }) {<\/p>\n\n\n\n

return (<\/p>\n\n\n\n

{…rest}<\/p>\n\n\n\n

render={(props) => isLoggedIn ? <Component {…props} \/> : <Redirect to=”\/” \/><\/p>\n\n\n\n

}<\/p>\n\n\n\n

\/><\/p>\n\n\n\n

);<\/p>\n\n\n\n

}<\/p>\n\n\n\n

\/\/ Usage;
<PrivateRoute exact path=”\/dashboard” component={Dashboard} isLoggedIn={isLoggedIn} \/>
<\/p>\n\n\n\n
