When web scraping with Puppeteer we might encounter pages that require scrolling to the bottom to load more content. This is a common pattern for infinite scrolling pages.

To scroll our Puppeteer browser custom javascript function `window.scrollTo(x, y)` can be used. This function scrolls the page to the specified coordinates.

So, if we need to scroll to the very bottom of the page we can use a `while` loop to continuously scroll until the bottom is reached. Let's take a look at an example by scraping [web-scraping.dev/testimonials](https://web-scraping.dev/testimonials):

javascript```javascript
const puppeteer = require('puppeteer');

async function scrapeTestimonials() {
    const browser = await puppeteer.launch({headless: false});
    const page = await browser.newPage();

    await page.goto('https://web-scraping.dev/testimonials/');

    let prevHeight = -1;
    let maxScrolls = 100;
    let scrollCount = 0;

    while (scrollCount < maxScrolls) {
        // Scroll to the bottom of the page
        await page.evaluate('window.scrollTo(0, document.body.scrollHeight)');
        // Wait for page load
        await page.waitForTimeout(1000);
        // Calculate new scroll height and compare
        let newHeight = await page.evaluate('document.body.scrollHeight');
        if (newHeight == prevHeight) {
            break;
        }
        prevHeight = newHeight;
        scrollCount += 1;
    }

    // Collect all loaded data
    let elements = await page.$$('.testimonial');
    let results = [];
    for(let element of elements) {
        let text = await element.$eval('.text', node => node.innerHTML);
        results.push(text);
    }

    console.log(`Scraped: ${results.length} results!`);

    await browser.close();
}

scrapeTestimonials();
```



Above, we're scraping an endless paging example from the `web-scraping.dev` website. We start a `while` loop and keep scrolling to the bottom until the browser's vertical size stops changing. Then, once the bottom is reached we can start parsing the content.
