import { PUBLIC_ENVIRONMENT } from '$env/static/public'
import { CLOUDFLARE_TURNSTILE_PRIVATE_KEY } from '$env/static/private'
import { validate, CLOUDFLARE_TURNSTILE_PRIVATE_KEY_ALWAYS_PASSES } from '@feelinglovelynow/svelte-turnstile'

const fields = Object.fromEntries((await request.formData()).entries())
const secret = (PUBLIC_ENVIRONMENT === 'local') ? CLOUDFLARE_TURNSTILE_PRIVATE_KEY_ALWAYS_PASSES : CLOUDFLARE_TURNSTILE_PRIVATE_KEY

await validate(fields['cf-turnstile-response'], secret)
