unfurl

unfurl is a kotlin library that generates link previews by extracting their social metadata.

val unfurler = Unfurler()
println(unfurler.unfurl("https://saket.me/great-teams-merge-fast/"))

UnfurlResult(
  url = "https://saket.me/great-teams-merge-fast", 
  title = "Great teams merge fast", 
  description = "Observations from watching my team at Square produce stellar work while moving fast and not breaking things.", 
  favicon = "https://saket.me/wp-content/uploads/2022/03/cropped-saket-photo-180x180.jpg", 
  thumbnail = "https://saket.me/wp-content/uploads/2021/02/great_teams_merge_fast_cover.jpg"
)

unfurl is extensible. See TweetUnfurler as an example for unfurling tweets that can't be HTML scraped.

val unfurler = Unfurler(
  extensions = listOf(TweetUnfurler(), ...)
)
