Core Patterns

Basic Script

const puppeteer = require('puppeteer');

(async () => {
    const browser = await puppeteer.launch({ headless: 'new' });
    const page = await browser.newPage();
    await page.setViewport({ width: 1280, height: 720 });

    await page.goto('https://example.com', { waitUntil: 'networkidle0' });
    await page.type('#username', 'user@test.com');
    await page.type('#password', 'password123');
    await page.click('button[type="submit"]');
    await page.waitForNavigation({ waitUntil: 'networkidle0' });

    const title = await page.title();
    console.log('Title:', title);

    await browser.close();
})();

Wait Strategies

// Wait for selector
await page.waitForSelector('.result', { visible: true, timeout: 10000 });

// Wait for navigation
await Promise.all([
    page.waitForNavigation({ waitUntil: 'networkidle0' }),
    page.click('a.nav-link'),
]);

// Wait for function
await page.waitForFunction('document.querySelector(".count").innerText === "5"');

// Wait for network request
const response = await page.waitForResponse(resp =>
    resp.url().includes('/api/da
