[Feature] a hook mechanism to augment cross-cutting logic

[devalex88]

Hi Playwright developers. Thank you so much for this great framework. One thing I would love to see in Playwright is the ability to intercept commands send to browsers for handling some cross-cutting concerns such as logging. Is it currently available or in the roadmap?

Could you share more about your goal?

@pavelfeldman I'm looking for something like this https://www.selenium.dev/selenium/docs/api/java/org/openqa/selenium/support/events/WebDriverEventListener.html. As an example I would be able to capture the screenshots after every page.click().

[pavelfeldman]

Got it. For screenshots to work, you need async hooks that we await for and we don't have those. It is a fine idea though, so I'm leaving this open as a feature request.

Thank you @pavelfeldman. Just to clarify, did you mean that non-async hooks were available?

[pavelfeldman]

No, I just meant to say that we would need hooks to be async as we are implementing them.

Closing this as a part of the triage, please feel free to file a new issue with additional details. Given the limited resource and a lot of requests, we need to fulfill most popular requests and at the same time keep our issue database manageable.
