How to Show a react-toastify Toast After Navigating to Another Page in React

Navigating between pages in a React application can sometimes lead to unexpected behavior, especially when you want to show a notification after a redirection. A common scenario arises when a function that submits data and subsequently navigates does not display a toast notification. In this guide, we will address this issue and present a straightforward solution that can help you display a react-toastify toast notification after navigating to another page.

The Problem

You might be using a function to submit data, and upon successful submission, you want to show a toast message before navigating to another page. However, after implementing navigation (often using react-router-dom for routing), the toast notification does not appear as expected. This was highlighted in a recent inquiry where the function for submission worked perfectly, but the navigation caused the toast to disappear.

Here's a simplified version of the problematic code:

In this example, the toast notification is generated, but immediately after calling navigate, the toast disappears as the page changes.

The Solution: Using setTimeout

After troubleshooting similar cases and trying various methods, a simple hack can effectively solve this problem. By using a setTimeout, you can delay the navigation slightly, allowing the toast notification to render on the screen successfully. Here’s how to implement this solution:

Steps to Implement

Modify the Submit Handler: Update your submitHandler to include a setTimeout function that delays the navigation. This allows the toast to display before the page redirection occurs.

Explanation of the Code

navigate("/allpatients");: Initiates the navigation to the intended route.

setTimeout(() => {...}, 1);: This sets a very short delay (1 millisecond) before executing the code inside it, effectively allowing the toast to display before navigating away.

Important Notes

Perceived Hack: While using setTimeout may feel like a hack, it is a workaround that effectively solves timing issues in scenarios where UI updates are involved.

Performance Considerations: A delay of 1 millisecond is minimal; however, it may be prudent to test in various environments to ensure performance meets expectations.

Rendering the Toast Container

Make sure that the ToastContainer component is present in the rendered output of the navigated page. Without it, the toast message won't be displayed. Here’s how you could render it:

By implementing the changes and ensuring that the toast container is properly set up, you'll be able to display your notification seamlessly across page navigations.

Conclusion

Navigating between pages in a React application while still showing notifications can be a bit tricky. However, by using a short delay with setTimeout, you can successfully display a react-toastify toast even after a page redirect. This ensures that users receive timely feedback on their actions, enhancing their overall experience with your application.

Implement this simple fix, and you'll have a smoother navigation experience with your toast messages showing up just as they should!
