Why is my React application displaying a blank page after upgrading to React Router v6?

Troubleshoot Blank Page in React Applications

When developing React applications, an occasional issue may arise where the page remains blank, leaving users perplexed. This article will delve into one of the most common causes for this problem and provide a solution.

Consider the following code snippet:

<code class="jsx">// App.js
import { Route } from "react-router-dom";
...
<Route exact path="/" component={Home} />
<Route path="/wallet" component={Wallet} /></code>

As you have observed, you are using the component prop to render the respective React components in the Route definition. However, in React Router v6, this has changed significantly.

In React Router v6, the Route component expects the rendered content to be passed as a child element using the element prop instead of the component prop. This subtle difference can cause the page to remain blank.

To resolve this, you need to update your code as follows:

<code class="jsx">// App.js
import { Route } from "react-router-dom";
...
<Route exact path="/" element={<Home />} />
<Route path="/wallet" element={<Wallet />} /></code>

By using the element prop, you are passing the React components as children of the Route component, which is the correct approach in React Router v6.

Once you make this change, your React application should display the correct content on the designated routes, eliminating the frustrating blank page issue. Keep in mind, if you encounter similar problems in the future, double-checking the version of React Router you are using and adjusting your code accordingly should be a quick fix.
