07a — Guest PWA Routes & Components

This scaffold describes recommended routes, guards, directories, and components for the Guest PWA. It is framework-leaning (React Router v6 + Vite), but adaptable.

Routing Principles

• Event routes require an event token (from QR/PIN). Guard redirects to Landing when missing/invalid.
• Use route-level code splitting for camera/lightbox/slideshow.
• Prefer modal routes (photo detail) layered over the gallery.

Route Map (proposed)

• / — Landing (QR/PIN input; deep-link handler)
• /setup — Profile Setup (name/avatar; skippable)
• /e/:slug — Home/Feed (default gallery view + info bar)
• /e/:slug/tasks — Task Picker (random/emotion)
• /e/:slug/tasks/:taskId — Task Detail (card)
• /e/:slug/upload — Upload Picker (camera/library + tagging)
• /e/:slug/queue — Upload Queue (progress/retry)
• /e/:slug/gallery — Gallery index (alias of Home or dedicated page)
• /e/:slug/photo/:photoId — Photo Lightbox (modal over gallery)
• /e/:slug/achievements — Achievements (optional)
• /e/:slug/slideshow — Slideshow (optional, read-only)
• /legal/:page — Legal pages (imprint/privacy/terms)
• * — NotFound

Note: The settings experience is handled via the header sheet (no dedicated route; legal pages stay routable under /legal/:page).

Guards & Loaders

• EventGuard — verifies event token in storage; attempts refresh; otherwise redirects to /.
• PrefetchEvent — loads event metadata/theme on :slug routes.
• OfflineFallback — surfaces offline banner and queues mutations.

Router Sketch (React Router v6)

import { createBrowserRouter } from 'react-router-dom';
import EventGuard from './routes/EventGuard';
import PrefetchEvent from './routes/PrefetchEvent';

export const router = createBrowserRouter([
  { path: '/', element: <LandingPage /> },
  { path: '/setup', element: <ProfileSetupPage /> },
  {
    path: '/e/:slug',
    element: (
      <EventGuard>
        <PrefetchEvent>
          <HomeLayout />
        </PrefetchEvent>
      </EventGuard>

]);

Component Checklist

• Layout
  • Header, InfoBar (X Gäste online • Y Aufgaben gelöst), BottomNav, Toast.
• Entry
  • QRPinForm (QR deep link or PIN fallback), ProfileForm (name/avatar).
• Home/Feed
  • HeroCard (Willkommensgruess + Eventtitel) und StatTiles (online Gaeste, geloeste Aufgaben, letztes Upload).
  • CTAButtons (Aufgabe ziehen, Direkt-Upload, Galerie) + UploadQueueLink fuer Warteschlange.
  • EmotionPickerGrid und GalleryPreview als inhaltlicher Einstieg.
• Tasks
  • EmotionPickerGrid, TaskCard (shows duration, group size, actions).
• Capture/Upload (photos only)
  • CameraPicker, UploadPreviewList, UploadQueueList.
• Photo View
  • PhotoLightbox (modal), like/share controls, emotion tags.
• Settings & Legal
  • SettingsSheet (Header-Overlay mit Namenseditor, eingebetteten Rechtsdokumenten, Cache-Leeren), LegalPage Renderer.

State & Data

• TanStack Query for server data (events, photos); optimistic updates for likes.
• Zustand store for local-only state (profile, queue, banners).
• IndexedDB for upload queue; CacheStorage for shell/assets.
• i18n: react-i18next; load 'guest' namespace JSON from /lang/{locale}/guest.json; path-based detection for /de/e/:slug, /en/e/:slug; useTranslation('guest') in components.
• Polling: focus-aware intervals (10s stats, 30s gallery); use document visibility to pause; backoff on failures.

Accessibility & Performance

• Focus management on modal open/close; trap focus.
• Color contrast and minimum tap target sizes (44px).
• Code-split camera/lightbox/slideshow; prefetch next gallery page.

Out of Scope

• Video capture/upload is not supported.
