|
Puppeteer is a Node.js library which provides a high-level API to control
|
|
Chrome/Chromium over the
|
|
[DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/).
|
|
Puppeteer runs in
|
|
[headless](https://developer.chrome.com/docs/chromium/new-headless/)
|
|
mode by default, but can be configured to run in full ("headful")
|
|
Chrome/Chromium.
|
|
|
|
## Example
|
|
|
|
```ts
|
|
import puppeteer from 'puppeteer';
|
|
|
|
(async () => {
|
|
// 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('https://developer.chrome.com/');
|
|
|
|
// 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);
|
|
await page.click(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);
|
|
|
|
await browser.close();
|
|
})();
|
|
```
