grub-2.0 VS skyscraper

Not finished, but the Selenium based crawler works pretty well to combat most blocks: https://github.com/kordless/grub-2.0

For IP blocks, try this: https://github.com/kordless/mitta-screenshot

I started https://mitta.us as this, but am pivoting to prompt management for GPT-3. I've Open Sourced the code for the crawler here: https://github.com/kordless/grub-2.0. The entire system uses Google Vision for extracting text. I dislike fiddling with the DOM...

If you are interested in using Solr for this, I can provide instructions to you. I'm kordless at the gmails ... com.

Depending on the use case you might try imaging the page, then send the image to an ML model for full text before indexing. If you need links extracted, Selenium also supports parsing the assembled DOM: https://github.com/kordless/grub-2.0/tree/main/aperture

I’ve found imaging the page and doing OCR on the image is quite good for text extraction. Many pages on the Internet render with JavaScript, which means BS may not see the text in the DOM.

Here is the code to do some of that: https://github.com/kordless/grub-2.0

Yes!

My Clojure scraping framework [0] facilitates that kind of workflow, and I’ve been using it to scrape/restructure massive sites (millions of pages). I guess I’m going to write a blog post about scraping with it at scale. Although it doesn’t really scale much above that – it’s meant for single-machine loads at the moment – it could be enhanced to support that kind of workflow rather easily.

I plan to port my scraping framework (Skyscraper, https://github.com/nathell/skyscraper) to babashka one day. I’m not sure how easy it will be, though, since it uses core.async (which I believe bb has limited support for) and SQLite via clojure.java.jdbc.

I’ve done a fair share of scraping, and I learned that on a large scale, there are a lot of cross-cutting repetitive concerns. Things like caching, fetching HTML (preferably in parallel), throttling, retries, navigation, emitting the output as a dataset…

My library, Skyscraper [0], attempts to help with these. It’s written in Clojure (based on Enlive or Reaver, both counterparts to Beautiful Soup), but the principles should be readily transferable everywhere.
