Overview

unfurl

unfurl extracts social metadata of webpages for generating link previews, inspired by slack.

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 fully be HTML scraped.

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

implementation "me.saket.unfurl:unfurl:1.6.0"
implementation "me.saket.unfurl:unfurl-social:1.6.0" // For TweetUnfurler.

cli

$ brew install saket/repo/unfurl
$ unfurl https://saket.me/great-teams-merge-fast

Unfurler extensions can now include arbitrary metadata in unfurled links using UnfurlResult#contentPreview. TweetUnfurler uses this to populate tweet details such as username, profile photo, media attachments, etc.

Breaking changes

Renamed Logger to UnfurlerLogger and added an API to log exceptions that can be used with your error reporting service.

Removed HtmlMetadataParser to simplify API surface. You're encouraged to create an extension instead by subclassing HtmlTagsBasedUnfurler.
