# Puppeteer Automation Skill
|
|
|
|
## Core Patterns
|
|
|
|
### Basic Script
|
|
|
|
```javascript
|
|
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
|
|
|
|
```javascript
|
|
// 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
|
|
|
|
```javascript
|
|
await page.screenshot({ path: 'screenshot.png', fullPage: true });
|
|
await page.pdf({ path: 'page.pdf', format: 'A4', printBackground: true });
|
|
```
|
|
|
|
### Network Interception
|
|
|
|
```javascript
|
|
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](reference/cloud-integration.md).
|
|
|
|
```javascript
|
|
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=${encodeURIComponent(JSON.stringify(capabilities))}`,
|
|
});
|
|
```
|
|
|
|
## Quick Reference
|
|
|
|
| Task | Code |
|
|
|------|------|
|
|
| Launch headed | `puppeteer.launch({ headless: false })` |
|
|
| Evaluate JS | `await page.evaluate(() => document.title)` |
|
|
| Extract text | `await page.$eval('.el', el => el.textContent)` |
|
|
| Extract all | `await page.$$eval('.items', els => els.map(e => e.textContent))` |
|
|
| Set cookie | `await page.setCookie({ name: 'token', value: 'abc' })` |
|
|
| Emulate device | `await page.emulate(puppeteer.devices['iPhone 12'])` |
