Benefits of using scrapy over requests/selenium (lemmy.world)

When I'm writing webscrapers I mostly just pivot between selenium (because the website is too "fancy" and definitely needs a browser) and pure requests calls (both in conjunction with bs4).

But when reading about scrapers, scrapy is often the first mentioned Python package. What am I missing out on if I'm not using it?

The huge feature of scrapy is it's pipelining system: you scrape a page, pass it to the filtering part, then to the deduplication part, then to the DB and so on

Hugely useful when you're scraping and extraction data, I reckon if you're only extracting raw pages then it's less useful I guess

Oh shit that sounds useful. I just did a project where I implemented a custom stream class to chain together calls to requests and beautifulsoup.

Yep try scrapy. And also it handles for you the concurrency of your pipelines items, configuration for every part,...
