Structure Crawlers to scrape multiple sites
Hey everyone,
what is the recommended way to structure your code to scrape multiple sites? I looked at a few questions here and it seems that the recommended way is to use a single crawler but multiple routers to handle this case. the issue, I am facing from this is that when you enqueue links, you'll add
Is there a better way I can structure this? usecase is to setup crawlers for 10+ sites and crawl them sequentially or in parallel but having sane logging for them.

site-1site-1 and then site-2site-2 initally before starting the crawler and then the crawler will dynamically add in the links as needed but this will mess up the logs since we are using a Queue and its FIFO, so first it'll crawl the first link, add the extracted links to the queue and then crawl the second link and its links to the queue and like this it'll keep switching contexts between the two sites which will make the logs a mess. Also routers, dont seem to have a url parameter, its just a category and then the request, so we will have to basically define handlers for each site in a single router right? which will just bloat up a single file.Is there a better way I can structure this? usecase is to setup crawlers for 10+ sites and crawl them sequentially or in parallel but having sane logging for them.
