Module: Abqari::Indieweb::Bridgy

Defined in:
lib/abqari/indieweb.rb

Overview

Bridgy Fed + webmention.io link tags. Pure markup — no runtime logic. Layouts call these from <head> via the _head partial.

Bridgy Fed (fed.brid.gy) acts as the ActivityPub bridge: it speaks the federation protocol on the site's behalf and translates incoming AP activity into webmentions, which webmention.io catches for us. Net result: a Mastodon user can search @<your-domain> and follow the site directly, with their replies showing up under posts as ordinary webmentions.
