Step 1:vuejs javascript Google API Script

put the Google recaptcha simple javascript google api to your simple file Like as index.html

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

Recaptcha.vue

//Your simple template
<template>
  <div 
  id="g-recaptcha"
  class="g-recaptcha"
  :data-sitekey="sitekey">
  </div>
</template>

<script>
export default {
  data () {
    return {
	//your google sitekey
      sitekey: '5jsuj58LLkjsd55SKSJDddLive24u*********',
      vueWidgtId: 0
    }
  },
  methods: {
	//some vuejs methods
    execute () {
      window.grecaptcha.execute(this.vueWidgtId)
    },
    reset () {
		//reset using vuejs
      window.grecaptcha.reset(this.vueWidgtId)
    },
    render () {
		//render Functions using vuejs
      if (window.grecaptcha) {
        this.vueWidgtId = window.grecaptcha.render('g-recaptcha', {
          sitekey: this.sitekey, //get your sitekey
          size: 'invisible',
          callback: (results) => {
            this.$emit('verify', results)
            this.reset() 
          }
        })
      }
    }
  },
  mounted () {
    this.render()
  }
}
</script>

Step 3:

Import the Google recaptcha component data as well as Put it to your web-page Live website(parent component).

page.vue

<template>
  <div>
    <h1>Vuejs Parent component Pakainfo.com</h1>
    <button @click="executeRecaptcha">Run recaptcha</button>
    <recaptcha ref="recaptcha" @verify="submit"></recaptcha>
  </div>
</template>

<script>
import Recaptcha from 'recaptcha'
export default {
  components: {
    Recaptcha
  },
  methods: {
    submit (results) {
      console.log(results)
    },
    executeRecaptcha () {
      this.$refs.recaptcha.execute()
    }
  }
}
</script>

reCAPTCHA with Vue.js example

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

After that define live_api_key_rcapt in Vuejs data:

export default {
    data() {
      return {
        live_api_key_rcapt: "GOOGLE_API_KEY_FOR_YOUR_WEBSITE",
        liveid_recaptcha: 0 // will be used later
      }
    }
}

And also we some api script need to load js in google global HTML section:

<script src='https://www.google.com/recaptcha/api.js'></script>

And then , To solve this we can HTML render google captcha on vue mounted hook:

mounted() {
  if (window.grecaptcha) {
    this.liveid_recaptcha = grecaptcha.render( $('.g-recaptcha')[0], { sitekey : this.live_api_key_rcapt });
  }
},

check that your Google captcha challenged by some user (for designer UX):

recapcha_google_res = grecaptcha.getResponse(this.liveid_recaptcha);
if (recapcha_google_res.length == 0) {
   this.error = "Some Compleate captcha more challenge. Sorry!";
   return
}

After that send recapcha_google_res to your server side backend to verify validation captcha.
