EmojiReact vs. Like w/ content? Hm... FEP-c0e0: Emoji reactions details two ways to federate an Emoji reaction: EmojiReact activity Like with content (as opposed to a regular Like, which has no content) In testing, I noticed that misskey (or at least, the site I was testing with, birb.space) sends the latter. I don't know what sends the former, and if NodeBB were to start federating out EmojiReact, would it be broadly understood? Perhaps I should federate out both at once. cc @silverpill@mitra.social

EmojiReact is used by Pleroma. Idk about others, I started with EmojiReact but then switched to Like - Mastodon users can see a "favorite" that way.

EmojiReact vs. Like w/ content? Okay, NodeBB can now be configured to send out EmojiReact (default) or Like. Of note, Misskey seems to assume it is :heart:, possibly missing support for EmojiReact.

The most portable solution we've found is to send a Note with InReplyTo containing nothing but a single emoji (which might be a composite emoji) after removing whitespace. The same algorithm on the receiving side also works for Like activities with single-emoji content. We treat these as emoji reactions internally. You can add one or more of the various 'EmojiReact' platform specific cohorts if you want. Just like punycode usernames - it federates with all the things. Unlike all the other solutions we've seen...
