Should we make development the default and change the conditions to detect the production environment instead? Then we wouldn't need the env file locally.

Done. That's a nice catch since there are no other envs we can default to dev.

FYI — this readme section was broken for a while and when we're at it, i'll probably remove it because it doesn't show all contributoes.

Your avatar will still be shown on tiny-helpers.dev though.

~~Is there a reason why args and defaultViewport are locally different than in prod?~~

Ahh. I see — because chromium isn't available. Could we still add --hide-scrollbars and --disable-web-security? 🤔

@realityzero Welcome to TH and thank you so much for contributing. 💯

This topic has been on the list for ages so I'm exited that someone is tackling it. I've left some comments and on the way and will test is locally once we discussed these.

Thanks again and have a great day!

@realityzero I just checked out the branch and have run vercel dev (I should document this 🤦‍♂️ ).

Unfortunately, it's not working locally and I'm running in target closed errors.

What's your local setup to test this?

realityzero · 2024-03-21T08:02:28Z

@stefanjudis Apologies for getting onto this quite late. I couldn't test the solution end to end locally from tiny-helpers project. However, I followed the same abstracted approach of picking platform specific chromium in one of my recent projects: ScrapifyX.

That's my bad.

Could you please try this out: Stackoverflow

Or just tell me how to invoke screenshot.js after running this project. I was unable to find any references from UI.

stefanjudis · 2024-03-25T07:24:10Z

@realityzero

Apologies for getting onto this quite late.

No worries. I'm still very grateful that you're taking this on! 🎉

Or just tell me how to invoke screenshot.js after running this project.

That's my bad. As this project is deployed to vercel I run it via the CLI which I have installed globally.

I also looked briefly into this and no SO magic helped out for the local screenshoting. :/

realityzero · 2024-03-29T12:54:45Z

@stefanjudis
Whenever I've read TargetCloseError or Target closed in Puppeteer, it is almost always a memory issue. Can you try adding adding following args:

Let's just add this first --disable-dev-shm-usage
If it still breaks, add one more argument --shm-size=3gb

Ref:

puppeteer/puppeteer#1790
puppeteer/puppeteer#1175

stefanjudis · 2024-03-29T15:46:11Z

@realityzero Unfortunately, neither of the options work.

I'm still running into the same exceptions. Did you try the Vercel CLI to see how to tackle it?

realityzero · 2024-04-07T09:55:02Z

Hey @stefanjudis ! Apologies man for such a late reply. Certain life challenges.

I did some debugging locally in two different stages.

Look at this diff (github wasn't allowing me to upload a .patch file)

I simply executed node screenshot.js. Here I was able to get a base64 and used some base64 to image converted online and it went fine.
2. I tried vercel dev command to replicate the same connection level thing of deployment. However I couldn't navigate to a page that takes screenshots. I might need help in that. But it triggered screenshot.js behind the scenes in terminal and executed same thing as point 1.

How about we get over a call for this in the coming week?

stefanjudis · 2024-05-13T18:12:26Z

@realityzero Hey, so sorry for letting this slip through. :/ Life's pretty wild on my end.

But in the meantime, something changed on vercel's side and things broke entirely. I think I'll move the screenshots off serverless fns. It's just to briddle. ;/

Sorry for wasting your time.
