# Story 2.5.2: Event Management Frontend

# Status

In progress

# Story

As a user (Organizer), I want a React frontend interface for event management with dashboard, CRUD forms, workflow visualization, and timeline views, so that I can efficiently manage events through an intuitive user interface.

# Domain Context

# Primary Domain

Event Management Domain - Frontend React application consuming Event Management Service APIs

# Involved Services

• Frontend: React application (TypeScript, Material-UI, Zustand, React Query)
• Backend: Event Management Service (REST APIs from Story 2.2)
• Backend: Speaker Coordination Service (speaker assignment data)
• Backend: Venue Management (venue booking and logistics)
• Backend: Company Management Service (company data for speakers)
• Backend: User Management Service (team assignments, organizer roles)
• CDN: CloudFront for event images and materials
• Cache: React Query for client-side caching (5-15min TTL)

# Cross-Domain Dependencies

Foundation Dependencies (MUST be complete):

• Depends on: Story 1.17 (React Frontend Foundation) - DONE ✅

  • Provides: BaseLayout, AppHeader, NavigationMenu, NotificationDropdown, UserMenuDropdown, LanguageSwitcher, ErrorBoundary
  • Provides: Shared components (components/shared/), hooks (useAuth, useNotifications, useBreakpoints)
  • Provides: i18n infrastructure (react-i18next, translation files in public/locales/de/ and public/locales/en/)
  • Provides: Zustand stores (authStore, uiStore), React Query configuration, Material-UI theme
  • Provides: Routing with ProtectedRoute, responsive breakpoints, accessibility (WCAG 2.1 AA)
  • Location: Components in web-frontend/src/components/shared/, hooks in web-frontend/src/hooks/

• Depends on: Story 1.9 (Error Handling Essentials) - DONE ✅

  • Provides: Standardized error response format { timestamp, path, status, error, message, correlationId }
  • Provides: Exception hierarchy (ValidationException, NotFoundException, UnauthorizedException, ServiceException)
  • Provides: Error codes (ERR_VALIDATION, ERR_NOT_FOUND, ERR_UNAUTHORIZED, ERR_SERVICE)
  • Provides: Correlation ID propagation via X-Correlation-ID header and MDC
  • Frontend Impact: Use error response format in API client error interceptor, display correlation IDs in error messages

Backend Dependencies:

• Depends on: Story 1.11 (Security & Compliance Essentials) for JWT authentication and input validation
• Depends on: Story 1.16.2 (Eliminate UUIDs from API) for meaningful ID pattern (eventCode, username, companyName)
• Depends on: Story 2.2 (Event Management Service Core + API Consolidation) - DONE
  • Provides: Event CRUD APIs, workflow management, slot assignment, overflow management
  • Provides: Consolidated API with ?include=workflow,speakers,sessions,venue resource expansion

Service Integration:

• Consumes: Event Management Service consolidated APIs with ?include=workflow,speakers,sessions,venue resource expansion
• Consumes: Speaker Coordination Service for speaker details
• Consumes: Venue Management for venue selection
• Consumes: User Management Service for team assignments
• Integrates with: API Gateway for authentication and routing

Important: This story uses meaningful IDs only (no UUIDs) as defined in Story 1.16.2:

• Events identified by eventCode (e.g., “BATbern56”)
• Users identified by username (e.g., “john.doe”)
• Companies identified by name (e.g., “GoogleZH”)
• UUIDs remain internal to database layer only

Reusable Foundation from Story 1.17:

• ✅ BaseLayout component (already implemented)
• ✅ AppHeader with role-adaptive navigation (already implemented)
• ✅ NavigationMenu with organizer menu items (already implemented)
• ✅ i18n with react-i18next (German/English) (already implemented)
• ✅ API client with auth interceptors (already implemented)
• ✅ ErrorBoundary for component errors (already implemented)
• ✅ Zustand stores for UI state (already implemented)
• ✅ React Query for server state (already implemented)

• Resource Expansion: Uses ?include=workflow,speakers,sessions,venue,registrations to reduce API calls (90% reduction)
• Filtering: JSON filter syntax from Story 1.15a.1
• Caching: React Query with 5-15min staleTime for event data based on volatility

[Source: architecture/03-data-architecture.md#event-data-model]

• Event Entity: UUID identifier, title, description, eventDate, eventType, status, workflowState
• TypeScript Types: Generated from OpenAPI specifications

# Infrastructure Components

[Source: architecture/02-infrastructure-deployment.md]

Frontend Deployment:

• S3 + CloudFront: Static React app hosting

  }
}

Usage in Components:

import { useTranslation } from 'react-i18next';

const EventManagementDashboard: React.FC = () => {
  const { t } = useTranslation('events');

  return (
    <Container>
      <Typography variant="h4">{t('dashboard.title')}</Typography>
      <Button>{t('form.createEvent')}</Button>
    </Container>
  );
};

# Foundational Story Integration

This story builds directly on the following completed foundation stories:

1. Story 1.9 (Error Handling Essentials) - DONE

   • Use ErrorResponse format from shared-kernel: { timestamp, path, status, error, message, correlationId }
   • Display correlation IDs from X-Correlation-ID response header in error messages
   • Map error codes (ERR_VALIDATION, ERR_NOT_FOUND, ERR_UNAUTHORIZED, ERR_SERVICE) to user-friendly messages
   • Use GlobalExceptionHandler error response structure in API client error interceptor

2. Story 1.11 (Security & Compliance Essentials) - READY FOR REVIEW

   • JWT tokens automatically added to requests via axios interceptor (from API Gateway SecurityConfig)
   • Security headers (CSP, HSTS, X-Frame-Options) applied by API Gateway SecurityHeadersFilter
   • Input validation uses backend @Valid annotations with 400 error responses
   • Rate limiting handled by API Gateway RateLimitingFilter (60 req/min)
   • All form inputs sanitized and validated client-side before submission

3. Story 2.2 (Event Management Service Core + API Consolidation) - PENDING

   • Backend REST APIs: GET/POST/PUT/PATCH/DELETE /api/v1/events
   • Event workflow endpoint: GET/PUT /api/v1/events/{id}/workflow
   • Slot management endpoints: GET/POST /api/v1/events/{id}/slots
   • Overflow management: GET/POST /api/v1/events/{id}/overflow
   • Topic backlog: GET/POST /api/v1/topics/backlog
   • Consolidated API with ?include=workflow,speakers,sessions,venue,registrations (90% API call reduction)
   • Caffeine-cached responses (5-15min TTL) for <50ms cached, <500ms uncached response times

4. Story 1.17 (React Frontend Foundation) - DONE

   • React 19+ with TypeScript, Material-UI 7.x, Vite 7.x
   • Shared components: FormField, LoadingSpinner, ErrorMessage, ConfirmDialog, ToastNotification
   • React Router v6 with role-based route guards
   • Axios client with auth interceptor and error handling
   • React Query for server state management
   • Zustand for UI state (filters, modals)
   • i18next for internationalization (German/English)

Architecture Notes (per 05-frontend-architecture.md):

• Components organized by role (organizer/, speaker/, partner/, attendee/)
• Event management is organizer-specific, so components go in components/organizer/EventManagement/
• Hooks, services, stores, types, and utils are shared across the app (top-level directories)
• TypeScript types generated from OpenAPI specs via openapi-typescript in types/generated/

# Technical Design Notes

1. TypeScript Types (types/event.types.ts)

Type Generation Strategy (per 05-frontend-architecture.md):

• Use openapi-typescript to generate types from OpenAPI specs
• Generated types are committed to repository and kept in sync via git hooks
• Application types derive from generated types

# Generate types from OpenAPI spec
npm run generate:api-types
# Generates: src/types/generated/events-api.types.ts

// types/event.types.ts - Derive from OpenAPI-generated types
import type { components } from './generated/events-api.types';

// Derive application types from OpenAPI-generated types
export type Event = components['schemas']['EventResponse'];
export type EventDetail = components['schemas']['EventDetail'];
export type EventWorkflow = components['schemas']['EventWorkflow'];
export type Session = components['schemas']['SessionResponse'];
export type CreateEventRequest = components['schemas']['CreateEventRequest'];
export type UpdateEventRequest = components['schemas']['UpdateEventRequest'];

// Note: All IDs are meaningful identifiers (eventCode, username, companyName) per Story 1.16.2
// UUIDs are internal to database layer only, never exposed in API/frontend

// Extended interfaces for frontend-specific needs
export interface Event {
  id: string; // eventCode (e.g., "BATbern56")
  eventNumber: number;

  // ... 13 more steps
  AGENDA_FINALIZATION = 'agenda_finalization'
}

export interface CreateEventRequest {

  eventType: 'full_day' | 'afternoon' | 'evening';
  theme?: string;

  openEditModal: (eventCode: string) => void;
  closeEditModal: () => void;
}

2. React Query Hooks (hooks/useEvents.ts)

import { useQuery } from '@tanstack/react-query';
import { eventApiClient } from '../services/eventApiClient';
import { EventDetail, EventFilters } from '../types/event.types';

export const useEvents = (filters: EventFilters, page: number = 1, limit: number = 20) => {
  return useQuery({
    queryKey: ['events', filters, page, limit],
    queryFn: () => eventApiClient.getEvents(filters, page, limit),
    staleTime: 5 * 60 * 1000, // 5 minutes
    cacheTime: 10 * 60 * 1000, // 10 minutes
    keepPreviousData: true, // For pagination
  });
};

export const useEvent = (eventCode: string, include?: string[]) => {
  return useQuery({
    queryKey: ['event', eventCode, include],
    queryFn: () => eventApiClient.getEvent(eventCode, include),
    staleTime: 15 * 60 * 1000, // 15 minutes (full event with includes cached longer)
    enabled: !!eventCode,
  });
};

export const useEventWorkflow = (eventCode: string) => {
  return useQuery({
    queryKey: ['eventWorkflow', eventCode],
    queryFn: () => eventApiClient.getEventWorkflow(eventCode),
    staleTime: 10 * 60 * 1000, // 10 minutes
    enabled: !!eventCode,
  });
};

export const useCriticalTasks = (organizerId: string) => {
  return useQuery({
    queryKey: ['criticalTasks', organizerId],
    queryFn: () => eventApiClient.getCriticalTasks(organizerId),
    staleTime: 3 * 60 * 1000, // 3 minutes (more volatile)
    enabled: !!organizerId,
  });
};

export const useTeamActivity = (organizerId: string, limit: number = 20) => {
  return useQuery({
    queryKey: ['teamActivity', organizerId, limit],
    queryFn: () => eventApiClient.getTeamActivity(organizerId, limit),
    staleTime: 2 * 60 * 1000, // 2 minutes (very volatile)
    enabled: !!organizerId,
  });
};

export const useCreateEvent = () => {
  const queryClient = useQueryClient();

  return useMutation({
    mutationFn: (data: CreateEventRequest) => eventApiClient.createEvent(data),
    onSuccess: () => {
      queryClient.invalidateQueries(['events']);
      toast.success('Event created successfully');
    },
    onError: (error: AxiosError) => {
      toast.error(error.response?.data?.message || 'Failed to create event');
    },
  });
};

export const useUpdateEvent = () => {
  const queryClient = useQueryClient();

  return useMutation({
    mutationFn: ({ eventCode, data }: { eventCode: string; data: UpdateEventRequest }) =>
      eventApiClient.updateEvent(eventCode, data),
    onMutate: async ({ eventCode, data }) => {
      // Optimistic update
      await queryClient.cancelQueries(['event', eventCode]);
      const previousEvent = queryClient.getQueryData(['event', eventCode]);
      queryClient.setQueryData(['event', eventCode], (old: Event) => ({ ...old, ...data }));
      return { previousEvent };
    },
    onSuccess: (_, { eventCode }) => {

      } else {
        toast.error('Failed to delete event');

  });
};

3. Zustand Store (stores/eventStore.ts)

import { create } from 'zustand';
import { persist } from 'zustand/middleware';
import { EventStore, EventFilters } from '../types/event.types';

export const useEventStore = create<EventStore>()(
  persist(
    (set) => ({
      filters: {},
      selectedEventCode: undefined,
      isCreateModalOpen: false,
      isEditModalOpen: false,

      setFilters: (filters) => set({ filters }),
      setSelectedEventCode: (eventCode) => set({ selectedEventCode: eventCode }),
      openCreateModal: () => set({ isCreateModalOpen: true }),
      closeCreateModal: () => set({ isCreateModalOpen: false }),
      openEditModal: (eventCode) => set({ selectedEventCode: eventCode, isEditModalOpen: true }),
      closeEditModal: () => set({ isEditModalOpen: false, selectedEventCode: undefined }),
    }),
    {
      name: 'event-store', // LocalStorage key
      partialPersist: (state) => ({ filters: state.filters }), // Only persist filters
    }
  )
);

4. API Client (services/eventApiClient.ts)

import axios, { AxiosError } from 'axios';
import { Event, EventDetail, CreateEventRequest, UpdateEventRequest, EventFilters, EventWorkflow } from '../types/event.types';

const apiClient = axios.create({
  baseURL: import.meta.env.VITE_API_BASE_URL,
  timeout: 10000,
});

// Request interceptor for auth token
apiClient.interceptors.request.use((config) => {
  const token = localStorage.getItem('authToken');
  if (token) {
    config.headers.Authorization = `Bearer ${token}`;
  }
  return config;
});

// Response interceptor for error handling
apiClient.interceptors.response.use(
  (response) => response,
  (error: AxiosError) => {
    if (error.response?.status === 401) {
      // Redirect to login
      window.location.href = '/login';
    }
    return Promise.reject(error);
  }
);

export const eventApiClient = {
  getEvents: async (filters: EventFilters, page: number, limit: number): Promise<{ data: Event[]; pagination: any }> => {
    const params = new URLSearchParams();
    params.append('page', String(page));
    params.append('limit', String(limit));

    if (filters.status) {
      params.append('status', filters.status);
    }
    if (filters.year) {
      params.append('year', String(filters.year));
    }
    if (filters.eventType) {
      params.append('eventType', filters.eventType);
    }
    if (filters.searchQuery) {
      params.append('search', filters.searchQuery);
    }

    const response = await apiClient.get(`/api/v1/events?${params.toString()}`);
    return response.data;
  },

  getEvent: async (eventCode: string, include?: string[]): Promise<EventDetail> => {
    const params = include?.length ? `?include=${include.join(',')}` : '';
    const response = await apiClient.get(`/api/v1/events/${eventCode}${params}`);
    return response.data;
  },

  createEvent: async (data: CreateEventRequest): Promise<Event> => {
    const response = await apiClient.post('/api/v1/events', data);
    return response.data;
  },

  updateEvent: async (eventCode: string, data: UpdateEventRequest): Promise<Event> => {
    const response = await apiClient.patch(`/api/v1/events/${eventCode}`, data);
    return response.data;
  },

  deleteEvent: async (eventCode: string): Promise<void> => {
    await apiClient.delete(`/api/v1/events/${eventCode}`);
  },

  getEventWorkflow: async (eventCode: string): Promise<EventWorkflow> => {
    const response = await apiClient.get(`/api/v1/events/${eventCode}/workflow`);
    return response.data;
  },

  getCriticalTasks: async (username: string, limit: number = 10): Promise<any[]> => {
    // username is the organizer's username (e.g., "john.doe")
    const response = await apiClient.get(`/api/v1/organizers/${username}/tasks/critical?limit=${limit}`);
    return response.data;
  },

  getTeamActivity: async (username: string, limit: number = 20): Promise<any[]> => {
    // username is the organizer's username (e.g., "john.doe")
    const response = await apiClient.get(`/api/v1/organizers/${username}/activity-feed?limit=${limit}`);
    return response.data;
  },

  getDeletionImpact: async (eventCode: string): Promise<any> => {
    const response = await apiClient.get(`/api/v1/events/${eventCode}/deletion-impact`);
    return response.data;
  },
};

• Unsaved Changes Warning:
  • Detects dirty form state
  • Shows confirmation dialog before closing with unsaved changes
  • Allows user to confirm or cancel close
• Role-Based Access Control:
  • Only organizers can create/edit events
