🚀 Usage

✅ reCAPTCHA v3 (Invisible)

1. Import the component:

   import GoogleRecaptcha from 'google-recaptcha-vue3';

2. Integrate into your component template:

   <template>
     <GoogleRecaptcha
       ref="recaptchaRef"
       siteKey="your-site-key"
       action="submit"
       @verified="handleToken"
       @error="handleError"
     />
     </template>
   
   <script setup>
   import { ref } from 'vue';
   import GoogleRecaptcha from 'google-recaptcha-vue3';
   
   const recaptchaRef = ref(null);
   
   const handleToken = (token) => {
     console.log('Token:', token);
     // Send this token to your server for verification.
   };
   
   const handleError = (err) => {
     console.error("reCAPTCHA Error:", err);
   };
   
   // Trigger reCAPTCHA execution (e.g., on form submission)
   const submitForm = () => {
     recaptchaRef.value.execute();
     // ... other form submission logic
   };
   </script>

3. Trigger Execution:

   const recaptchaRef = ref(null);
   
   // Call this method when you need to verify the user action
   const triggerRecaptcha = () => {
     recaptchaRef.value.execute();
   };

4. Handle the emitted token and errors:

   const handleToken = (token) => {
     console.log('Token:', token);
     // Implement your server-side token verification logic here.
   };
   
   const handleError = (err) => {
     console.error("reCAPTCHA Error:", err);
     // Handle potential reCAPTCHA errors.
   };

✅ reCAPTCHA v2 (Checkbox)

1. Import the component:

   import GoogleRecaptcha from 'google-recaptcha-vue3';

2. Use it in your component template:

   <template>
     <GoogleRecaptcha
       siteKey="your-site-key"
       version="v2"
       autoLoad="true"
       @verified="handleToken"
       @error="handleError"
     />
   </template>
   
   <script setup>
   import { ref } from 'vue';
   import GoogleRecaptcha from 'google-recaptcha-vue3';
   
   const handleToken = (token) => {
     console.log('Token:', token);
     // Send this token to your server for verification.
   };
   
   const handleError = (err) => {
     console.error("reCAPTCHA Error:", err);
   };
   </script>

3. Handle the emitted token and errors:

   const handleToken = (token) => {
     console.log('Token:', token);
     // Implement your server-side token verification logic.
   };
   
   const handleError = (err) => {
     console.error("reCAPTCHA Error:", err);
     // Handle any reCAPTCHA errors.
   };

4. Manually Load reCAPTCHA (when autoLoad is false):

   const recaptchaRef = ref(null);
   
   // Call this method to explicitly load the reCAPTCHA widget
   const loadRecaptcha = () => {
     recaptchaRef.value.execute(); // Note: For v2, 'execute' will render the checkbox if not already loaded.
   };

🛠️ Methods

• execute(): Triggers the reCAPTCHA process. For v3, it programmatically invokes the invisible challenge. For v2 (when autoLoad is false), it can be used to initiate the rendering of the checkbox.

• RecaptchaV3Example.vue: Demonstrates the usage of the invisible reCAPTCHA v3.
• RecaptchaV2Example.vue: Illustrates the integration of the reCAPTCHA v2 checkbox.

🧪 Test Keys

For local development and testing purposes, you can utilize Google's provided test site keys:

• v3 Site Key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI
• v2 Site Key: 6LeIxAcTAAAAAJcZVRqyHh71UMIEGNQ_MXjiZKhI

⚠️ Important: These test keys will always return a valid token. Never use them in production environments. Replace them with your site keys obtained from the Google reCAPTCHA admin console.
