Feature Request: Implement Page.screenshot APIs for screen capture

[sj817]

import puppeteer from 'puppeteer-core'

(async () => {
  const browser = await puppeteer.connect({ browserWSEndpoint: 'ws://127.0.0.1:9222', })
  const page = await browser.newPage()
  await page.goto('https://github.com')
  await page.screenshot({ path: 'test.webm' })
  process.exit()
})()

In the realm of browser automation, the screenshot API is critical. I look forward to lightpanda delivering faster and more efficient screenshot capabilities.

Hello @sj817
Thanks for the issue.
Unfortunately Lightpanda browser doesn't handle graphical rendering, so it can't generate screenshots.
As alternative, I could suggest you to get the final HTML and use something like servo to render the HTML and generate a screenshot.
But I'm not sure if it a real solution in your case.

I think the real problem here is debugging flow.
If smth is wrong, how I really debug it?
My typical usecase here will be add some JS debug, to highlight some dom elements, and etc.

Hello @buger,
I think one way to debug would be to dump the html returned by Lightpanda and inspect it using a web browser.

But I understand this is not a live view and it's harder to follow.
Maybe we could think of another solution in the future, but it's clearly not our priority for now.
