Hi!
I made a Kirby plugin to implement the Openheart protocol on my blog. It provides the possibility to add (almost any) emoji reactions to any page on a Kirby-powered website.
After copying the code to your site/plugins directory, you’ll have to add calls to specific snippets in your templates, and fields/sections to your site and page blueprints.
I am releasing this plugin as-is: I will not have the time to handle the inclusion in the Composer repository, nor will I be able to ensure its long-term support. Egregious bugs might be fixed, but I cannot promise anything. PRs and forks are welcomed.
The plugin does not include a rate limiter, so use it at your own risk (or please add a rate limiter if you know how to do it!).
