froala_editor.min.js
is the minified version of the Froala editor without any plugins whatsoever. froala-compiled.min.js
is the editor plus all of the plugin files that we use in XF.
We include the minified editor plus all Froala plugins (not just the ones we use - in the vendor/froala/plugins directory) so that people can compile their own version of Froala with whichever plugins they need within their own add-ons for specific use cases.
Semi related, but we ship and use xf/editor-compiled.js which includes the Froala compiled file plus our custom editor code.
