I'm too hesitant to use it in prod because of the pricing risk (it's beta still anyways) so don't have any real prod use to compare the price.

I was testing to capture screenshot for top 5k top domains from CF - https://radar.cloudflare.com/domains to test if we can migrate our Screenshot API from AWS (https://agenty.com/tools/webpage-to-screenshot)

I created a queue to send request to D0 to capture screenshot and upload
But the queue is getting error randomly :

So it sems the D1 browser reset automatically and the new launch fails to create the browser.

What I would like is to be able to start a "Durable Browser" and be charged per "Durable Browser" session started. CF would then handle all that behind the scenes stuff to keep the browser open and running (and restarting after crashes, or memory leaks, or whatever) and I don't have to worry about it. And then I can know in my code that I'm only registering 1 or 5 or 10, and then I can manage it accordingly. I'm not sure how that would work from a scalability perspective. But I can't stomach the volatility of either being charged pennies or thousands of dollars because of a memory leak in the browser, which I can't control, crashing and restarting. Or even things like deploying new code or attaching to the log viewer; if I understand right, my durable objects get reset; which starts a new browser session.

questions about sessions and number of pages and geography. I saw that for $5 a month you get 500 sessions. I was wanting to check multiple search results on certain google searches. 1. Is there a way to define the cloudflare geographic node making the remote request. 2. Is there a limit to how many pages I could view in a single session? 3. Can I block this service from other cloudflare customers using this on my domains? 4. (general puppeteer question..can't find a conclusive answer in google) Is there a good suggestion on how to add a simple timestamp to screen shot with the lowest overhead?

captain•1/8/24, 11:32 PM

(for #4, I injected a new div node with the time stamp before taking a screenshot and that solved my issue!) Now reading back about needing to create and keep open a durable object to maintain a single session if necessary to avoid going over 500 and seeing that it says open as long as there is not a empty 60 seconds. SO if I had had a cront job that checked perhaps a 100 pages with a sleep delay of 3 seconds to allow the content to load before doing a screen shot, and say this cron runs once a day then theoretically it can run 15 minutes giving me the opportuity to run 15 * 60 / 3 = 300 pages in a single cron job max per session

P

Pedro•1/9/24, 8:07 AM

Hey @captain, you can indeed keep a session open using durable objects and check multiple search results with the same session. Please find an example here: https://developers.cloudflare.com/browser-rendering/get-started/browser-rendering-with-do/

We are making changed to the product so that in the future you won't have to manage the DO and keepint it alive. We also have plans to add geolocation, so you can choose where the request will be originated, but it is not yet available in current beta. Thanks for sharing your solution for the timestamp

I was able to work around this bug by manually clipping the viewport which is a bit annoying but works.

page.screenshot({ clip: { x: 0, y: lastScroll || 0, width: data.innerWidth, height: data.innerHeight } })

page.screenshot({ clip: { x: 0, y: lastScroll || 0, width: data.innerWidth, height: data.innerHeight } })

page.screenshot({ clip: { x: 0, y: lastScroll || 0, width: data.innerWidth, height: data.innerHeight } })

page.screenshot({ clip: { x: 0, y: lastScroll || 0, width: data.innerWidth, height: data.innerHeight } })
