Solved: react router 404 redirect

The main problem related to React Router 404 redirect is that it can be difficult to implement. Since React Router does not have a built-in 404 page, developers must manually create a route for the 404 page and then configure the router to redirect any requests that do not match an existing route. This requires additional code and configuration, which can be time consuming and difficult to debug if something goes wrong. Additionally, if a user navigates directly to a URL that doesn’t exist, they will still see an error page instead of being redirected to the 404 page.

import { BrowserRouter as Router, Route, Switch } from "react-router-dom";

const App = () => (
      <Route exact path="/" component={Home} />
      <Route exact path="/about" component={About} />

      {/* 404 Redirect */}
      <Route render={() => (<Redirect to="/" />)} /> 


// Line 1: This line imports the BrowserRouter, Route, and Switch components from the react-router-dom library.

// Line 3: This line defines a function called App that returns JSX.

// Lines 5-7: These lines wrap the App component in a Router component from react-router-dom.

// Lines 8-10: These lines define two routes for the Home and About components respectively.

// Line 12: This line defines a route that redirects to the Home page if no other route matches.

What is a 404 Error Code

A 404 error code in React Router is an HTTP status code that indicates that the requested resource could not be found. It is usually returned when a user attempts to access a page or route that does not exist. This can occur if the user has mistyped a URL, or if the page has been removed or moved without updating the links to it. When this occurs, React Router will display a generic 404 page with an appropriate message informing the user of their error.

404 Redirect

In React Router, a 404 redirect is a way to redirect users to a different page when they try to access an invalid URL. This can be useful for providing users with a better experience when they enter an incorrect URL or try to access a page that doesn’t exist. The 404 redirect can be implemented using the Redirect component from React Router, which allows you to specify the pathname of the page you want to redirect the user to. For example, if someone tries to access /invalid-url, you could use the Redirect component like this:
