Navigating to Homepage After Form Submission in React

When developing a React application, you often need to handle user interactions such as form submissions. A common requirement is to redirect users to a different page upon successfully submitting a form. In this guide, we will address how to navigate to the homepage after a form submission using react-router-dom v6.2.1.

Problem Overview

In our scenario, we have a phone directory application with two main pages: the ShowSubscribers page (/) for displaying subscribers and the AddSubscribers page (/add) for adding new subscribers. The challenge is to redirect users back to the ShowSubscribers page after they submit the form on the AddSubscribers page.

While previously used methods might not work as expected in certain versions, we will explore how to properly handle routing in React when using class components together with react-router-dom.

Understanding the Requirement

Here’s what we want to achieve upon form submission in the AddSubscribers component:

Submit the form data for adding a new subscriber.

Clear the form fields after submission.

Redirect the user to the ShowSubscribers page (/).

The Existing Approach

The initial attempt to use this.props.history.push("/") for redirection didn’t yield the expected results. This is primarily because the latest versions of react-router-dom have transitioned to using hooks instead of the older approach to manage navigation within class components.

Solution Steps

To resolve this issue, we will simplify our routing logic by downgrading to react-router-dom v5.2.1, which supports the class component’s history prop functionality. Here’s a step-by-step guide to implementing the solution:

Step 1: Downgrade react-router-dom

Make sure to change the version of react-router-dom in your package.json file as follows:

After updating, run npm install or yarn install to install the desired version.

Step 2: Update Routing in PhoneDirectory

Next, you’ll need to modify the PhoneDirectory component to utilize the appropriate components for routing:

Step 3: Implement Redirection in AddSubscriber

Now, redirect the user back to the homepage after form submission. Modify the AddSubscriber component as follows:

Conclusion

By following the steps above, you should now be able to redirect users to the homepage (/) after they submit the form on the AddSubscribers page. This solution leverages react-router-dom v5.2.1, which is compatible with class component navigation techniques, ensuring a seamless user experience.

Feel free to implement these practices in your own React applications to manage routing smoothly during form submissions!
