This is a Next.js project bootstrapped with create-next-app.

Getting Started

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

Check-in API contract

QR links use /checkin/{eventSlug}. On page render, the server requests GET {CHECKIN_API_BASE_URL}/events/{eventSlug} and expects:

{
  "id": "event-id",
  "title": "Event title",
  "dateTime": "2026년 9월 19일(토) 13:00",
  "description": "Optional form description",
  "submissionEndpoint": "/events/event-id/check-ins"
}

On submit, the client sends POST to submissionEndpoint with:

{
  "eventId": "event-id",
  "name": "김젝트",
  "phone": "01012345678"
}

When CHECKIN_API_BASE_URL is empty, local mock event and submission responses are used.
