import puppeteer from 'puppeteer-core';
import { Lexmount } from 'lexmount';
const client = new Lexmount();
let session;
let browser;
try {
session = await client.sessions.create({ browserMode: 'normal' });
if (!session.connectUrl) throw new Error('Session has no CDP URL');
browser = await puppeteer.connect({ browserWSEndpoint: session.connectUrl });
const page = (await browser.pages())[0] ?? await browser.newPage();
await page.goto('https://example.com', { waitUntil: 'domcontentloaded' });
console.log(await page.title());
} finally {
try {
await browser?.disconnect();
} finally {
try {
await session?.close();
} finally {
client.close();
}
