Capture screenshots of websites in various resolutions. A good way to make sure your websites are responsive. It's speedy and generates 100 screenshots from 10 different websites in just over a minute. It can also be used to render SVG images.

See pageres-cli for the command-line tool.

npm install pageres

Note to Linux users: If you get a "No usable sandbox!" error, you need to enable system sandboxing.

The specified function is called right before the screenshot is captured, as well as before any bounding rectangle is calculated as part of options.element. It receives the Puppeteer Page instance as the first argument and the browser instance as the second argument. This gives you a lot of power to do custom stuff. The function can be async.

Note: Make sure to not call page.close() or browser.close().

import Pageres from 'pageres';

await new Pageres({
	delay: 2,
	beforeScreenshot: async (page, browser) => {
		await checkSomething();
		await page.click('#activate-button');
		await page.waitForSelector('.finished');
	}
})
	.source('https://github.com/sindresorhus/pageres', ['480x320', '1024x768'], {crop: true})
