What are the best practices for taking screenshots with Puppeteer?

When taking screenshots with Puppeteer, consider the following best practices: 1. Set the viewport size to match the desired screenshot dimensions. 2. Use the fullPage option for capturing entire pages. 3. Ensure that all resources are loaded before taking the screenshot. 4. Use appropriate image formats like PNG or JPEG based on your needs.

How can I ensure that all resources are loaded before taking a screenshot?

You can use the page.waitForNetworkIdle() method to wait until there are no more than a specified number of network connections for a certain amount of time. This ensures that all resources are fully loaded.

What viewport size should I use for mobile screenshots?

For mobile screenshots, a common viewport size is 375x667 pixels, which simulates an iPhone 6/7/8. You can set this using page.setViewport({ width: 375, height: 667 });.

Can I take screenshots of specific elements instead of the whole page?

Yes, you can take screenshots of specific elements by using the elementHandle.screenshot() method. First, select the element using page.$(selector) to get the element handle.
