Guide to Closing a Modal with the Browser Back Button in React Router v6

Using React Router v6 is a great way to manage routing in your React application. However, many developers encounter challenges when trying to implement modal functionality, especially when it comes to using the browser’s back button to close a modal. In this post, we will tackle this issue by providing a clear, step-by-step solution.

Understanding the Problem

You may have a modal that displays a larger version of a picture when a user clicks on a thumbnail. The challenge is to ensure that when a user presses the back button on their browser, the modal closes instead of navigating away from the current page. The method for handling this has changed from previous versions of React Router, leading many developers to seek assistance, especially with the introduction of the useNavigate() hook in v6.

Solution Overview

To achieve this functionality, we'll leverage the URL to determine if the modal is open or closed. Essentially, we will execute the following:

Use the URL to indicate modal state: Change the URL for when the modal opens and closes.

Define routes: Set up clear routes for both the photo list and the modal detail view.

Step 1: Define Your Routes

Set up your routes within the Routes component to handle both views: the photo list and the modal to show the larger image details. Here's how:

/photos: This route will display the list of photos.

/photos/:id: This will render the photo detail modal when a photo is clicked.

Step 2: Implementing the Modal Trigger

In your photo list component, allow users to open the modal by changing the URL using a link. This ensures that when a photo thumbnail is clicked, the URL updates, resulting in the modal being displayed:

Step 3: Browser History Management

With the above setup, React Router will handle browser history for you. Here's how:

When the user clicks a thumbnail, the URL changes from /photos to /photos/1 (assuming the photo’s ID is 1).

When the user hits the back button, they will navigate back to the previous URL, which will automatically close the modal, reverting the view back to the photo list.

Important Considerations

Ensure you do not add the exact keyword in the /photos route. This is crucial as it allows the photo list to be displayed underneath an open modal.

If you wish to manage the modal’s open/closed state more actively, you can also consider using local component state, but for many scenarios, managing via URL is a cleaner approach.

Conclusion

Implementing a modal that closes with the back button in React Router v6 does require some thoughtful setup of your routes and links. By following these steps, you can enhance the user experience in your application and take full advantage of browser navigation.

Now, your users can use the back button intuitively, making your application feel more polished and user-friendly. If you have any additional questions or need further clarification on implementing this or other React Router features, feel free to ask!
