Example Use:

from crawlee.playwright_crawler import PlaywrightCrawler
from .routes import router

async def main() -> None:
    """The crawler entry point."""
    crawler = PlaywrightCrawler(
        request_handler=router,
        max_requests_per_crawl=50,
    )

    @crawler.pre_navigation_hook
    async def hooky(context) -> None:
        print(f'Hook1')

    @crawler.pre_navigation_hook
    async def hooky2(context) -> None:
        print(f'Hook2')

    await crawler.run(
        [
            'https://crawlee.dev',
        ]
    )

Very cool! Could you please add a test of the functionality as well? Also, some documentation would be great, if you have the time.

[Prathamesh010]

I have added a test and made the suggested changes. @janbuchar

Also, some documentation would be great, if you have the time.

What type of documentation needs to be added? Will it be an example or a guide or something else?

[janbuchar]

Just extending the PlaywrightCrawler example should be enough for now.

[Prathamesh010]

Documentation is updated. @janbuchar

[janbuchar]

Almost there!
