Displaying Google Recaptcha V3 Floater on Specific Pages in Your React Application

Implementing Google Recaptcha V3 can enhance the security of your React application, but ensuring that it only shows up on relevant pages can be a challenge. If you want the Recaptcha badge to appear only on selected routes, such as login and forms, you’re in the right place! In this guide, we’ll walk you through the process of showing the Recaptcha badge exclusively on specific pages in your React application.

The Challenge:

You have a React application with multiple routes and a need to display the Recaptcha V3 badge only on certain pages—like login and forms. Having it pop up everywhere can be distracting and may harm user experience.

Why Recaptcha V3 is Important

Recaptcha V3 helps prevent spam and abuse by analyzing traffic and allowing only legitimate interactions. It provides a frictionless user experience by running in the background, only asking for verification when necessary.

Solution Overview

To control the visibility of the Recaptcha badge depending on the route, you need to utilize a combination of CSS and JavaScript. Here’s a structured approach to achieve this:

Toggle Badge Visibility with JavaScript:
Create a function that will allow you to show or hide the Recaptcha badge depending on the page the user is currently on.

React’s useEffect Hook:
Use the useEffect hook to handle component lifecycle and manipulate the badge visibility when components mount and unmount.

Step-by-Step Implementation

1. Declare the Toggle Function Outside Your Component

You need to define a function called toggleCaptchaBadge that will change the visibility of the Recaptcha badge based on the passing parameter:

Explanation: This function checks if the badge element exists. If it does, it sets its visibility to either visible or hidden based on the show parameter.

2. Use the useEffect Hook Inside Your Component

Next, implement the useEffect hook within your component to manage the badge's visibility during the component’s lifecycle:

How it Works:

The toggleCaptchaBadge(true) call will show the badge when the component mounts.

The return statement with toggleCaptchaBadge(false) will hide the badge when the component unmounts.

3. Apply the Functionality to Specific Pages

You should invoke the above logic in the login and form components, where you want the Recaptcha badge to show. This way, on those specific pages, your users will see the Recaptcha floater without it cluttering other routes in your React app.

Conclusion

By following the steps outlined above, you can seamlessly control the visibility of the Google Recaptcha V3 badge in your React application. Not only does this improve the user interface, but it also ensures that users are only presented with verification when necessary, maintaining a smooth experience while enhancing security.

Make your application both secure and user-friendly by implementing these techniques effectively!

Additional Tips

Testing: After implementing the changes, make sure to thoroughly test the visibility of the Recaptcha badge across different routes to ensure everything functions smoothly.

Customization: You can also customize the badge's appearance through CSS if necessary, depending on your app’s design.
