What is the best way to validate recaptcha response in vue.js component?

One of the best ways to validate a reCAPTCHA response in a Vue.js component is to use Google's official reCAPTCHA API. Here's a step-by-step guide to implement this in your Vue.js component:

  1. Inside your Vue component, import the following script tag to load Google's reCAPTCHA API:
1

<script src="https://www.google.com/recaptcha/api.js" async defer></script>


  1. Add a div element with the class "g-recaptcha" to your template, where you want the reCAPTCHA widget to be displayed:
1

<div class="g-recaptcha" data-sitekey="YOUR_SITE_KEY"></div>


Replace "YOUR_SITE_KEY" with the actual site key you obtained when setting up reCAPTCHA.

  1. Add a method in your Vue component to handle the reCAPTCHA response:

methods: {
    handleReCaptcha(response) {
        // Validate the reCAPTCHA response here
        // For example, you can send the response to your backend server for verification
        console.log('reCAPTCHA response:', response);
    }
}


  1. Add an event listener in the mounted hook of your Vue component to handle the reCAPTCHA widget:

        callback: (response) => {
            this.handleReCaptcha(response);
        }
    });
}


  1. Finally, remember to set up server-side validation to verify the reCAPTCHA response in your backend server to ensure security.
