Basic usage​

A typical use case for the MessageReactions component would be to use in your custom components that will completely override the message component.

@Component({
  selector: "app-custom-message",
  template: `
    <stream-message-reactions
      [isSelectorOpen]="isReactionSelectorOpen"
      [messageId]="message.id"
      [messageReactionCounts]="message.reaction_counts"
      [latestReactions]="message.latest_reactions"
      [ownReactions]="message.own_reactions"
    ></stream-message-reactions>
    <!-- Other parts of the custom message component -->
  `,
})
export class CustomMessageComponent {
  @Input() message: StreamMessage;
  isReactionSelectorOpen: boolean;
}
