Taking screenshots with Puppeteer is very simple, all you have to do is to set the browser's viewport, then use the page.screenshot() method to capture it.
Here's an example on how to take a screenshot of ScrapingBee's home page:
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
// Set the viewport's width and height
await page.setViewport({ width: 1920, height: 1080 });
// Open ScrapingBee's home page
await page.goto('https://scrapingbee.com');
try {
// Capture screenshot and save it in the current folder:
await page.screenshot({ path: `./scrapingbee_homepage.jpg` });
} catch (err) {
console.log(`Error: ${err.message}`);
} finally {
await browser.close();
console.log(`Screenshot has been captured successfully`);
}
})();
