Saving and loading cookies with Puppeteer is very straightforward, we can use the page.cookies() method to get all the cookies of a webpage, and use the page.setCookie() method to load cookies into a web page:
const puppeteer = require('puppeteer');
(async () => {
const browser = await puppeteer.launch();
const page = await browser.newPage();
// Open ScrapingBee's URL
await page.goto('http://scrapingbee.com');
// Get all the page's cookies and save them to the cookies variable
const cookies = await page.cookies();
// Open a second website
await page.goto('http://httpbin.org/cookies');
// Load the previously saved cookies
await page.setCookie(...cookies);
// Get the second page's cookies
const cookiesSet = await page.cookies();
console.log(JSON.stringify(cookiesSet));
await browser.close();
})();
