Vue 3, Nuxt 3 & Svelte 5 / SvelteKit Integration

Integrate dynamic purchasing power parity pricing into modern reactive Vue and Svelte applications with sub-10ms edge resolution.

Vue 3 / Nuxt 3 Reactive Integration

Consume the ParityEdge Edge API inside a Vue component or Nuxt plugin to reactively render regional discount banners and mutated checkout links:

<script setup lang="ts">
import { ref, onMounted } from 'vue';

interface ParityData {
  eligible: boolean;
  countryName: string;
  discountPercentage: number;
  couponCode: string | null;
}

const parity = ref<ParityData | null>(null);
const loading = ref(true);

onMounted(async () => {
  try {
    const res = await fetch('https://parityedge-edge-api.g-saichakri.workers.dev/v1/resolve?projectId=YOUR_PROJECT_ID');
    parity.value = await res.json();
  } finally {
    loading.value = false;
  }
});
</script>

<template>
  <div v-if="parity?.eligible" class="p-3 bg-emerald-500/10 border border-emerald-500/30 rounded-xl text-emerald-600 dark:text-emerald-400 text-xs">
    <span>Special {{ parity.discountPercentage }}% discount for visitors from {{ parity.countryName }}!</span>
    <span class="font-mono font-bold ml-1">Use coupon {{ parity.couponCode }}</span>
  </div>
</template>

Svelte 5 & SvelteKit Integration

Using Svelte 5 Runes ($state), mount localized pricing widgets in your root layout:

<script lang="ts">
  import { onMount } from 'svelte';

  let parity = $state<{
    eligible: boolean;
    discountPercentage: number;
    couponCode: string | null;
  } | null>(null);

  onMount(async () => {
    const res = await fetch('https://parityedge-edge-api.g-saichakri.workers.dev/v1/resolve?projectId=YOUR_PROJECT_ID');
    parity = await res.json();
  });
</script>

{#if parity?.eligible}
  <aside class="parity-pill">
    <span>Save {{ parity.discountPercentage }}% today!</span>
    <code>{{ parity.couponCode }}</code>
  </aside>
{/if}
