Websocket context Timeout

[KThrishul]

Hi, We are facing the error "websocket url timeout reached" when we reach request limit of 200

Here is the code example:

ctx, cancel := context.WithTimeout(context.TODO(), 30*time.Second)
defer cancel()
secondCtx, cancel := chromedp.NewContext(ctx)

Could you please help me out..

A browser instance consumes many resources and a system has limited resources. You should try to limit the number of browser instances/tabs. Usually, you can use a channel to do that. See https://go.dev/doc/effective_go#channels.

And usually, it's better to use a single browser instance. See #752 (comment).

Thank you, that did solve my problem.

I do have one more question. How to we limit the system resource while converting html to pdf using PrintToPdf for a single instance.

I can see that resources are used by the following:

1. Renderer
2. Utility
3. Zygote --no-zygote-sandbox
4. Zygote --no-sandbox
5. gpu-process

Are all this process are required to convert. If not, can we discard any of it. If yes, how?
Please help with this.

The behavior of the browser is controlled by the switches. You can find a full list of the switches here: https://peter.sh/experiments/chromium-command-line-switches/.

I don't know which combination of the switches will make it consume less resources. Generally, chromedp/headless-shell consumes less resources. You can give it a try.
