import { ThuumClient } from '@thuum/client';

// Your server's token route: it keeps the App Key, the browser gets a short-lived token.
const { token } = await fetch('/playground/wire/4yfgmx5q9g/token').then((r) => r.json());

const thuum = new ThuumClient({ baseUrl: 'https://api.thuum.dev' });
const socket = thuum.domain('thuum', token).wireBroker.connect();
await socket.ready;

// Delivered to whoever is subscribed right now; nothing is stored.
const { id, ts } = await socket.pub('playground:4yfgmx5q9g', 'reading', { "temperature": 21.5 });

Runs in the browser. The token route belongs to your server, which keeps the App Key.
