<script lang="ts">
  import showToast from '@feelinglovelynow/toast'
  import { PUBLIC_ENVIRONMENT } from '$env/static/public'
  import { Turnstile, PUBLIC_KEY_ALWAYS_PASSES } from '@feelinglovelynow/svelte-turnstile'

  const PUBLIC_KEY = 'get-from-cloudflare-turnstile-dashboard'

  function getTurnstileState (e: CustomEvent) { // if form is submitted before this callback no token will be passed in the form (aka) token validation will fail, typically takes less then 3 seconds after page load
    if (e.detail.status === 'success') isLoading = false // status options => [ 'success', 'error', 'expired', 'timeout' ] https://developers.cloudflare.com/turnstile/get-started/client-side-rendering/#configurations
    else showToast({ type: 'info', items: [ e.detail.message ] }) // message options => [ 'All good!', 'Network error', 'Token expired', 'Challenge expired' ] https://developers.cloudflare.com/turnstile/get-started/client-side-rendering/#configurations
  }

<Turnstile on:state={ getTurnstileState } sitekey={ PUBLIC_ENVIRONMENT === 'local' ? PUBLIC_KEY_ALWAYS_PASSES : PUBLIC_KEY } />
