reacji is an emoji reaction, the use of a single emoji character in response to a post, introduced as a feature by Slack.
For collections of reacjis and examples see
Why should you support posting reacji posts?
One great reason is to own your reactions(👍👎😆🎉😕❤️🚀👀) to GitHub issues and comments by posting them on your own site and POSSEing (e.g. using Bridgy).
How to display
Display a reacji post itself with reply-context. Because a reacji is so minimal, it may appear meaningless or misleading without additional context. But because reacji are small, a normal reply context would be presentationally overwhelming and look awkward.
The reply context for a reacji should be similar to the reply context for a like, which tends to re-order the reply-context as the object of the like, rather than a header above it. At a minimum show the in-reply-to URL linked to itself, then additional information as it is available (e.g. name or summary of post), all of which can be wrapped in a
u-in-reply-to h-cite hyperlink. Some sample hypertext designs:
- 👍 to http://tantek.com/2018/102/t9/css-2-2
- 👍 to tantek.com’s post
- 👍 to CSS 2.2
How to markup
Markup a reacji response post as follows:
Post a reply (How to markup) where the content is a single emoji character. Thus
u-in-reply-to is required.
Note: if there is HTML in the content property, it may mess with emoji detection, so you should use
p-content, rather than
e-content for reacji reply posts.
<p class="h-entry"> <span class="p-name p-content">👍</span> to <a class="u-in-reply-to h-cite" href="http://tantek.com/2018/102/t9/css-2-2">CSS 2.2</a> ... <a class="u-url" href="...permalink of post..."> <time class="dt-published">2018-05-01 11:00-0700</time> </a> </p>
Can use div or li or even span instead of (or around) the p element depending on what works for your site and context, e.g. on a permalink or in-stream. Note the reply-context comes after the content which is atypical for reply-context hypertext design/markup in general.
In addition, if your reacji is at least a somewhat positive approval, you may want to add a
u-like-of class (in addition to
u-in-reply-to) to your link to the original post, so that even if the receiver only supports likes, they can count your response as a like, until they add support for receiving reacji.
(complete h-entry reacji as a positive response code example would be nice here, perhaps with a thumbs-up or heart or smileyface emoji)
IndieWeb examples of reply posts consisting of a single emoji character (individual reacji posts)
Ben Roberts supports individual reacji posts in Postly since 2015-12-16 (his birthday, send him a 🎂)
Aaron Parecki has been posting reacji since 2015-12-16.
Tantek Çelik has been posting reacji since 2015-12-16.
- is also a like post (hence the /f in the URL) for fallback purposes, so that targets that understand likes but not reacji at least get the positive sense of the reacji being communicated. This method only makes sense for like-like reacji, but that's an acceptable limitation.
More recently (since 2018-04-13), reacji being posted as reply posts with a single emoji, e.g.:
Since 2018-05-02, showing in-stream mini-reply-contexts of the form:
👍 to issue 2588 of GitHub project “csswg-drafts”
Sebastiaan Andeweg sends reacji since 2017-02-20

Feed of reacji on Seblog, consisting of six separate reacji posts, in the format: "[emoji] on [post name] by [author name]."
Peter Molnar used to display reacji with Wordpress, then had them removed; now they are back again, but since it's a static site, they are display with significant delays - 2017-06-01
(permalinks needed that show displaying reacji from others)
Marty McGuire has been posting reacji since at least 2017-10-23.
- Post is in-reply-to the original post
- Content is single emoji character
Twitter seemed ready to roll out official support for 'reacji' but it was never widely released:
Without official support people have been experimenting on their own...
There are examples of individuals posting reacji as tweets (reacjweets as it were)
A tweet author can simulate a limited curated set of reacji by posting a survey with only single-emoji responses. E.g.
Tantek Çelik thoughts on reacji reply context design, deployed since brainstorming, have been incorporated into "How to display" above.
- We should call this reactions instead of reacji. The rest of the industry already does - Slack, Facebook, GitHub, etc. Common terminology is more valuable than minor semantic differences. (Lots more discussion in IRC.) - Ryan Barrett
- +1 Anthony Ciccarello Totally agree. Reactions is more in line with what I'd call similar features.
- +1 I agree and marked this as such in the Rust IndieWeb library — Jacky Alciné - 2022-12-17 12:27 EST
- -0 Tantek Çelik: technically yes, reacji *are* all reactions because they’re a proper subset of reactions which also include likes, reposts, bookmarks and other "one-click" / "one-keypress" actions taken in reaction (as it were) to posts. However calling reacji "reactions" is imprecise when you want to *only* talk about reacji.

In November 2019, Facebook staffers noticed they had a serious problem. Facebook offers a collection of one-tap emoji reactions. Today, they include “like,” “love,” “care,” “haha,” “wow,” “sad,” and “angry.” Company researchers had found that the posts dominated by “angry” reactions were substantially more likely to go against community standards, including prohibitions on various types of misinformation, according to internal documents.
