About
This is a simple component that helps deal with an invisible Google reCAPTCHA that you intend to invoke programmatically. There are a few plugins that help with Google's reCAPTCHA, but this one is focused on the invisble version with a programmatic invocation only. Due to its nature, reCAPTCHA can be a little complex - so that is what is driving the narrow scope here. Library supports easy multiple reCAPTCHAs on the same page.
Here's a breakdown of the steps you go through when using this library:
- Load the Google reCAPTCHA library using the provided
script
tag. - Whenever you'd like, invoke the reCAPTCHA using
this.$refs.invisibleRecaptcha1.execute()
method (replacinginvisibleRecaptcha1
with theref
name you set). - Google will either decide to show a challange or not. Either way, you'll get the
recaptchaToken
in the registeredrecaptcha-callback
event. Make sure to register for that. - Use that token to verify in your backend.
- Call the method again if you'd like to get a new token.
Usage Example
import VueProgrammaticInvisibleGoogleRecaptcha from 'vue-programmatic-invisible-google-recaptcha'
Vue.component('vue-programmatic-invisible-google-recaptcha', VueProgrammaticInvisibleGoogleRecaptcha)
<!-- Put this in your base HTML file - I use Vue CLI 3 so I put it at the bottom of the ./public/index.html file. -->
<script src="https://www.google.com/recaptcha/api.js?render=explicit" async defer></script>
<!-- This is in the component you want to have the reCAPTCHA -->
<vue-programmatic-invisible-google-recaptcha
ref="invisibleRecaptcha1"
:sitekey="'<YOUR_SITEKEY_HERE>'"
:elementId="'invisibleRecaptcha1'"
:badgePosition="'left'"
:showBadgeMobile="false"
:showBadgeDesktop="true"
@recaptcha-callback="recaptchaCallback"
></vue-programmatic-invisible-google-recaptcha>
<!-- Where you want to invoke the reCAPTCHA -->
submitButtonClicked() {
// Do whatever you want here (probably some validation). After
// that's done (or passed your expectations) you can then invoke the reCAPTCHA.
this.$refs.invisibleRecaptcha1.execute()
},
<!-- The reCAPTCHA's registered callback. This is where you'll get your token. -->
recaptchaCallback (recaptchaToken) {
// Use the `recaptchaToken` to pass to your backend to verify the token
axios.post('/enter', {recaptchaToken: recaptchaToken}).then((result) => {
console.log(result)
})
},
Note - I find it to be a good idea to allow the user to reset their reCAPTCHA on their own if they're experiencing an issue. This component exposes a function for this. To do this, give them a button with the following code in the click function: this.$refs.invisibleRecaptcha1.reset()
. This will reset the reCAPTCHA and hopefully get them passed the issue they're having.
Props

Methods
Note - call these methods through the ref
you set up with your component. Example: this.$refs.invisibleRecaptcha1.execute()
.
| method | parameters | description | |---------|-------|--------------------------------| | execute | none | Used to gather the token. If Google decides that the user needs to complete a test they'll do it here. | | reset | none | Used to reset the reCAPTCHA instance. |
Events
| event | parameter value | description | |---------|-------|--------------------------------| | recaptcha-callback | String | This even gets emitted when the token has been aquired. You can then use this token to verify the user on your backend. |
