How Reactions Work

• Each user can add one reaction of each type per comment
• Clicking the same reaction again removes it (toggle behavior)
• The reaction summary shows which users reacted with each emoji
• A CommentReacted event is dispatched with action: 'added' or 'removed'

Customizing Reactions

Override the emoji set in your config:

// config/comments.php
'reactions' => [
    'emoji_set' => [
        'thumbs_up' => "\u{1F44D}",
        'thumbs_down' => "\u{1F44E}",
        'heart' => "\u{2764}\u{FE0F}",
        'fire' => "\u{1F525}",
        'eyes' => "\u{1F440}",
    ],
],

Keys are stored in the database. If you change a key, existing reactions with the old key will no longer display.

Storage

Reactions are stored in the comment_reactions table with a unique constraint on (comment_id, user_id, user_type, reaction), ensuring one reaction of each type per user per comment.
