Puppeteer Automation Skill

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/data') && resp.status() === 200
);

Screenshot & PDF

await page.screenshot({ path: 'screenshot.png', fullPage: true });
await page.pdf({ path: 'page.pdf', format: 'A4', printBackground: true });

Network Interception

await page.setRequestInterception(true);
page.on('request', request => {
    if (request.resourceType() === 'image') request.abort();
    else request.continue();
});

// Mock API
page.on('request', request => {
    if (request.url().includes('/api/data')) {
        request.respond({
            status: 200,
            contentType: 'application/json',
            body: JSON.stringify({ items: [] }),
        });
    } else request.continue();
});

For full setup, capabilities, and shared capability reference, see reference/cloud-integration.md.

const capabilities = {
    browserName: 'Chrome', browserVersion: 'latest',
    'LT:Options': {
        platform: 'Windows 11', build: 'Puppeteer Build',
        user: process.env.LT_USERNAME, accessKey: process.env.LT_ACCESS_KEY,
    },
};

const browser = await puppeteer.connect({
    browserWSEndpoint: `wss://cdp.lambdatest.com/puppeteer?capabilities=${encodeURIComponent(JSON.stringify(capabilities))}`,
});
