Migrating out of PostHaven. Amjith Ramanujam decided to migrate his blog content from PostHaven to a Markdown static site. He used shot-scraper (shelled out to from a Python script) to scrape his existing content using a snippet of JavaScript, wrote the content to a SQLite database using sqlite-utils, then used markdownify (new to me, a neat Python package for converting HTML to Markdown via BeautifulSoup) to write the content to disk as Markdown.

Dumping the HTML of a page using shot-scraper. New in 1.0 is the “shot-scraper html URL” command, which outputs the HTML of a page once JavaScript has finished executing there. You can pass in additional custom JavaScript to run before the shapshot is taken, and you can also specify a CSS selector on the page to return just that fragment of HTML.

shot-scraper 1.0 (via) Only a minor release in terms of features, but I decided that I’m comfortable enough with the CLI design at this point that I’m ready to stamp a 1.0 on it and commit to not making backwards-incompatible changes (at least without shipping a 2.0 release, which I’d like to avoid if possible).

@newshomepages (via) Ben Welsh used my shot-scraper tool and GitHub Actions to launch a Twitter bot which tweets screenshots of newspaper homepages on a scheduled basis. Ben says: “The tech is so easy, I was able to pull it off in a couple hours at zero cost. A decade ago I ran a similar project using the cloud resources of the day. [...] It costs thousands of dollars and the screenshots were of much lower quality. Incredible progress!”
