/>API Reference
ReactionBar
Renders a row of reaction chips, each a button with aria-pressed reflecting whether you have reacted. Reactions use the exported Reaction type: { emoji: string; count: number; reacted?: boolean }. Pass reactions to control the list from outside, or defaultReactions to let it manage its own state. Toggling a chip adjusts its count by one, and a chip whose count reaches zero is removed.
| Prop | Type | Default | Description |
|---|---|---|---|
reactions | Reaction[] | - | Controlled reactions. Leave undefined for uncontrolled usage |
defaultReactions | Reaction[] | [] | Initial reactions when uncontrolled |
onReactionsChange | (reactions: Reaction[]) => void | - | Fires with the next reactions array on every change |
availableEmojis | string[] | ["👍", "❤️", "😂", "🎉", "😮", "🚀"] | Emojis offered in the add popover |
addable | boolean | true | Show the plus button that opens the emoji popover |
size | "sm" | "md" | "md" | Visual size of the chips |
className | string | - | Additional classes merged with the default container styles |
