</head>
<body>
<div
id="scalar-client"
class="scalar-app scalar-client"></div>
<script
type="module"
src="./main.js"></script>
</body>
</html>
// main.js
import { createApiClientApp } from '@/App'
// Initialize
await createApiClientApp(document.getElementById('scalar-client'), {
url: 'https://cdn.jsdelivr.net/npm/@scalar/galaxy/dist/latest.json',
proxyUrl: 'https://proxy.scalar.com',

document.getElementById('scalar-client'),
{
url: 'https://cdn.jsdelivr.net/npm/@scalar/galaxy/dist/latest.json',
proxyUrl: 'https://proxy.scalar.com',

open()
// Or: Open a specific operation
