用 CSS Selector 產生 RSS feed

Hacker News 首頁看到「Show HN: RSS feeds for arbitrary websites using CSS selectors (vincenttunru.com)」這個,程式在 GitLab.com 上的「Feed me up, Scotty!」這邊,另外這個專案名稱是在玩 Star Trek 的梗:「Beam me up, Scotty」,然後這邊講的 RSS feed 已經算是通稱了,實際上大家都是輸出 Atom

他用的設定檔格式是 TOML,文章給的範例:

[funfacts]
title = "Wikipedia — did you know?"
url = "https://en.wikipedia.org/wiki/Main_Page"
entrySelector = "#mp-dyk > ul li"
titleSelector = "b"
linkSelector = "b a"

[wikivoyage]
title = "Wikivoyage recommendations"
url = "https://en.wikivoyage.org/wiki/Main_Page"
entrySelector = ".jcarousel-wrapper .jcarousel-item"
titleSelector = "h2"
linkSelector = "h2 a"

feed-me-up-scotty/src/index.ts 這邊看起來是 TypeScript 專案,然後用 browser 帶起 Firefox 來,可以預期會吃不少資源...

另外 Hacker News 的討論裡有另外提到「Feed Creator」,看起來也是個不錯的專案,有免費版與付費版...
