I have the following Router definition:
<Router>
<Route exact path='/' component={Home}/>
<Route path='/about' component={About}/>
<Route path='/code' component={Code}/>
</Router>
I want any unmapped route (i.e /foo) to redirect back to root /.
I tried <Redirect .../> without success. Also adding a <Route /> without a path= resulted in a duplicated component on each page.

To go back to the previous page, pass -1 as a parameter to the navigate() function, e.g. navigate(-1) . Calling navigate with -1 is the same as hitting the back button. Similarly, you can call the navigate function with -2 to go 2 pages back.
React Router is used to define multiple routes in the application. When a user types a specific URL into the browser, and if this URL path matches any 'route' inside the router file, the user will be redirected to that particular route.
Now that you are familiar with the purpose of a Router, you will now learn about the Fallback Route which is a route a bundle passes through only when it cannot pass through any other route within a scenario hence the name fallback.
Using componentDidUpdate method of React page lifecycle, you can handled or disabled go back functionality in browser. basically componentDidUpdate method will call automatocally when component got updated. so once your component is updated you can prevent to go back as below.
What is the difference between React Router and React Router DOM? React Router is the core package for the router. React Router DOM contains DOM bindings and gives you access to React Router by default. In other words, you don’t need to use React Router and React Router DOM together.
In this article, we’ll look at how to define nested routes with React Router. To define nested routes, first, we define a grandchild route to display the content of the nested routes. We can use the useParams hook to get any route parameters. Then we can define nested routes by defining a child component to hold our nested routes.
Editor’s note: This React Router DOM tutorial was last updated on 11 August 2021. It may still contain information that is out of date. We’ve covered React Router extensively, including how to use Hooks alongside and instead of React Router, how to use React Router with Redux, and other advanced use cases.
These client-side routing rules update the browser’s window location without making requests back to the server. If you refresh the page or navigate directly to locations generated by client-side routing rules, a server-side fallback route is required to serve the appropriate HTML page.
Just place a redirect at the bottom like this and wrap your routes with Switch:
<Router>
<Switch>
<Route exact path='/' component={Home}/>
<Route path='/about' component={About}/>
<Route path='/code' component={Code}/>
// Redirect all 404's to home
<Redirect to='/' />
</Switch>
</Router>
