Velt Reactions Best Practices

Implementation guide for the Velt Inline Reactions feature — emoji reactions anchored to specific elements of your app (articles, posts, images, charts, custom UI). One root component, one required prop, optional custom emoji map, and a rich wireframe layer for building custom UI.

When to Apply

Reference these guidelines when:

• Adding inline reactions to a page section, post, or any container with a stable element id
• Binding <VeltInlineReactionsSection> to that container via targetReactionElementId
• Configuring custom reaction emojis (image URLs, alternate iconUrl, or unicode emoji)
• Calling client.getReactionElement().setCustomReactions(...) from non-React or runtime code
• Building custom reaction UI (custom pin, custom emoji picker, custom tooltip) via the wireframe tags
• Reading componentConfig.annotation, componentConfig.isReactionSelectedByCurrentUser, componentConfig.tooltipVisible, or the per-iteration user / emoji / isSelected context variables
• Typing against ReactionAnnotation / ReactionPinType

Related Velt skills

• Comment reactions — comments and reactions share the same setCustomReactions config; the same custom emoji map flows through commentElement.setCustomReactions(...) (see velt-comments-best-practices). Configure once at the right scope; don't duplicate per feature.
• Self-hosting reaction data — velt-self-hosting-data-best-practices documents the resolver-request shapes for persisting reactions yourself (SaveReactionResolverRequest, DeleteReactionResolverRequest, etc.). Cross-reference, don't duplicate.

Rule Categories by Priority

Quick Reference

API (HIGH)

• api-setup — <VeltInlineReactionsSection targetReactionElementId="..."> placement (must match container id); customReactions prop + client.getReactionElement().setCustomReactions() runtime method; the three custom-emoji entry shapes (url, iconUrl, emoji)

Wireframe Variables (MEDIUM)

• wireframe-variables-reactions — three primary wireframe tags (tool / pin / inline-section); full componentConfig.* reference per scope; nested decomposition (reactions-panel items, pin tooltip user rows); context-specific per-iteration variables (user, emoji, isSelected); flat-config access pattern

Types (MEDIUM)

• types-reaction-annotation — ReactionAnnotation shape (annotationId, from, reactions, commentAnnotationId, targetElement, targetElementId, position, type='reaction', etc.); ReactionPinType enum ('comment' | 'inline' | ...); cross-link to self-hosting resolver-request shapes
