How to Validate Recaptcha With Laravel And Vue.js?

To validate reCaptcha with Laravel and Vue.js, you can first integrate Google reCaptcha with your Laravel application by adding the necessary keys in your .env file and placing the reCaptcha script on your frontend.

Next, you can create a Vue component that renders the reCaptcha widget and listens for the user's response. You can then use Axios to make a POST request to your Laravel backend along with the reCaptcha token.

In your Laravel controller, you can use the Google reCaptcha API to verify the token sent from the frontend. If the token is valid, you can proceed with the desired action, such as submitting a form or approving a request.

Finally, you can handle the response from the reCaptcha verification in your Vue component and display appropriate messages to the user based on the verification result.

Overall, integrating reCaptcha with Laravel and Vue.js involves setting up the reCaptcha keys, frontend widget, making POST requests to the backend, verifying the token in Laravel, and handling the response in your Vue component.

What are the best tools for analyzing reCAPTCHA performance in Laravel and Vue.js projects?
