// Launch the browser and open a new blank page
const browser = await puppeteer.launch();
const page = await browser.newPage();

// Navigate the page to a URL
await page.goto('');

// Set screen size
await page.setViewport({width: 1080, height: 1024});

// Type into search box
await page.type('.devsite-search-field', 'automate beyond recorder');

// Wait and click on first result
const searchResultSelector = '.devsite-result-item-link';
await page.waitForSelector(searchResultSelector);

// Locate the full title with a unique string
const textSelector = await page.waitForSelector(
'text/Customize and automate'
const fullTitle = await textSelector?.evaluate(el => el.textContent);

// Print the full title
console.log('The title of this blog post is "%s".', fullTitle);
