method Page.prototype.setViewport
import { Page } from "https://deno.land/x/puppeteer@14.1.1/vendor/puppeteer-core/puppeteer/common/Page.js";

page.setViewport will resize the page. A lot of websites don't expect phones to change size, so you should set the viewport before navigating to the page.

In the case of multiple pages in a single browser, each page can have its own viewport size.

Examples

Example 1

const page = await browser.newPage();
await page.setViewport({
width: 640,
height: 480,
deviceScaleFactor: 1,
});
await page.goto('https://example.com');

Returns

Promise<void>
