RSVP

When you need a headcount for an event, such as a team dinner, an RSVP block lets members answer going, maybe or can’t go. Only the member who added it sees the organizer details and controls.

src/app.ts

import { createReintersectApp } from "@reintersect/sdk/app";
import { rsvp } from "@reintersect/sdk/recipes";

export const TeamDinner = rsvp({
  type: "team-dinner",
  title: "Team dinner",
  labels: { declined: "Not this time" },
});

export const app = createReintersectApp({ name: "Events" }).addBlock(TeamDinner);

export const autumnDinner = TeamDinner.insert({
  title: "Autumn team dinner",
  startsAt: "2026-10-16T18:30:00Z",
  location: "The Winding Stair, Dublin",
  capacity: 24,
});

Props, state and actions

Props are { title, startsAt?, location?, capacity? } (capacity a positive integer). State is { going, maybe, declined, closed }. Answers are a viewer input named rsvp with the values going, maybe and declined.

Action	Behaviour
`tally`	Runs after each answer and copies the counts into state. Hidden from agents (`agent: false`).
`close`	Destructive. Stops answers, posts the headcount and marks the block final.

The organizer section (the declined count) and the Close RSVPs button both use audience="creator", so only the member who added the block sees them. With a capacity, a progress bar labelled spots (“Spots taken”) shows how full the event is, and Reintersect writes its text, such as “12 of 24”.
