Creating a Back Button with React Router
To create a back button using React Router:
-
Set the property on the button
onClick
to the function. -
Use
useNavigate()
hooks, for exampleconst navigate = useNavigate();
. -
Call
navigate()
the function, passing it-1 - navigate(-1)
.
import {Link, Routes, Route, useNavigate} from 'react-router-dom';
export default function App() {
const navigate = useNavigate();
return (
<div>
<button onClick={() => navigate(-1)}>Go back 1 Page</button>
<button onClick={() => navigate(1)}>Go forward 1 Page</button>
<div>
<nav>
<ul>
<li>
<Link to="/">Home</Link>
</li>
<li>
<Link to="/contacts">Contacts</Link>
</li>
</ul>
</nav>
{/* 👇️ Wrap your Route components in a Routes component */}
<Routes>
<Route path="/contacts" element={<Contacts />} />
<Route path="/" element={<Home />} />
</Routes>
</div>
</div>
);
}
function Home() {
return <h2>Home</h2>;
}
function Contacts() {
return <h2>Contacts</h2>;
}
useNavigate
The hook returns a function that lets us navigate programmatically, such as after submitting a form or clicking a button.
To return to the previous page, pass -1 as an argument to
navigate()
the function, for examplenavigate(-1)
.
Invoking navigation with -1 is the same as clicking the back button in your browser.
Likewise, we can call the function with -2navigate
to go back 2 pages.
We can also use navigate
functions to programmatically navigate to different routes, navigate(/contacts)
e.g.
import {useNavigate} from 'react-router-dom'; export default function App() { const navigate = useNavigate(); const handleClick = () => { // 👇️ replace set to true navigate('/contacts', {replace: true}); }; return ( <div> <button onClick={handleClick}>Navigate to /contacts</button> </div> ); }
When the replace property options
of a object is set to true , the current entry in the history stack will be replaced by the new entry.
In other words, navigating to a new route will not push a new entry into the history stack, so if the user clicks the back button, they will not be able to navigate to the previous page.
This is useful, for example, when a user is logged in - we don't want them to be able to click the back button and return to the login page.
Or if we have a route that will use redirects to different pages - we don't want the user to click the back button and be redirected again.
If we need to navigate forward one page, call 1 - navigate(1)
navigation using .
To use the hook in your application useNavigate
, make sure the component in your index.jsApp
file is wrapped in a router.
import {createRoot} from 'react-dom/client';
import App from './App';
import {BrowserRouter as Router} from 'react-router-dom';
const rootElement = document.getElementById('root');
const root = createRoot(rootElement);
// 👇️ wrap App in Router
root.render(
<Router>
<App />
</Router>
);
The best place to wrap your React application with the Router component is in the index.js file, since this is the entry point for your React application.
Once your entire app Router
is wrapped in a component, you can use any hook from the react router package anywhere in the component.
