Basic Usage Example

If you just want the minimal init + login flow without the full styled card, here's the simplest version:

<template>
  <button @click="handleLogin">Sign in with Praman</button>
</template>

<script setup>
import { onMounted } from 'vue';
import { initPraman, loginWithPraman } from '@praman-network/sdk';

onMounted(() => {
  // Initialize with your developer API Key
  initPraman({
    apiKey: 'pm_dev_your_api_key_here',
    backendUrl: 'https://auth.praman.network'
  });
});

const handleLogin = async () => {
  try {
    const authResult = await loginWithPraman();
    console.log('User Authenticated:', authResult);
  } catch (err) {
    console.error('Authentication error:', err);
  }
};
</script>
