React Router Changes URL but Not View

If you are working with React and React Router, you may have encountered a situation where the URL changes but the view does not update accordingly. This can be a frustrating issue, but fortunately, there are a few possible solutions to this problem.

Solution 1: Ensure Proper Route Configuration

The first thing to check is your route configuration. Make sure that you have set up your routes correctly and that the components you want to render for each route are specified.

Here’s an example of how a basic route configuration should look like:

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

function App() {
  return (
    
      
        
        
        
      
    
  );
}
    

Make sure that you have imported the necessary components and that the paths are correct. Also, ensure that you are using the correct router component (in this case, BrowserRouter).

Solution 2: Use the withRouter Higher-Order Component

If your components are not receiving the updated route props, you can use the withRouter higher-order component provided by React Router. This will wrap your component and pass the updated route props to it.

Here’s an example of how to use withRouter:

import { withRouter } from 'react-router-dom';

function MyComponent(props) {
  // Access route props using props.history, props.location, props.match
  // ...
}

export default withRouter(MyComponent);
    

By wrapping your component with withRouter, you can access the route props (history, location, and match) and use them to update your view accordingly.

Solution 3: Use the key Prop to Force Component Remount

In some cases, React may not re-render a component if the key prop remains the same. To force a component remount, you can provide a unique key prop value whenever the URL changes.

Here’s an example of how to use the key prop:

import { Route, Switch, useLocation } from 'react-router-dom';

function App() {
  const location = useLocation();

  return (
    
      
      
      
    
  );
}
    

By providing the key prop with the value of location.key, you ensure that the component will remount whenever the URL changes.

Conclusion

If you are experiencing a situation where the React Router changes the URL but not the view, it can be due to incorrect route configuration, not receiving updated route props, or React not re-rendering the component. By following the solutions provided above, you should be able to resolve this issue and ensure that your view updates correctly.

Remember to double-check your route configuration, use the withRouter higher-order component if needed, and consider using the key prop to force component remounting.
