M3-10 Status Dashboard Tasks

🎯 VNF SDK Reference Implementation

PRIMARY REFERENCE: vnf-wallet-sdk-nodejs-main/

All status dashboard tasks MUST follow the official VNF SDK sample application patterns

Overview

Implementation of real-time credential status tracking dashboard with search, filter, and export capabilities for monitoring credential lifecycle using VNF SDK status tracking patterns.

Backend Tasks

Dashboard Data Service

• Task: Create comprehensive dashboard data aggregation
• Create dashboard.service.ts
• Implement credential status aggregation queries
• Add real-time statistics calculation (total, sent, claimed, expired)
• Create performance metrics tracking (processing times, success rates)

Search and Filter API

• Task: Implement advanced search and filtering
• Create credential-search.service.ts
• Add search by employee name, email, company, job title
• Implement date range filtering (upload date, credential date, expiration)
• Add status filtering with multiple selection support
• Create pagination for large result sets

Export Service

• Task: Generate reports and data exports
• Create export.service.ts
• Implement CSV export for credential data
• Add PDF report generation for compliance
• Create Excel export with multiple sheets (summary, details, errors)
• Add email delivery for large exports

Real-time Updates

• Task: WebSocket integration for live dashboard updates
• Create dashboard-websocket.gateway.ts
• Implement real-time credential status updates
• Add live processing progress broadcasts
• Create notification system for critical events

Dashboard Controller

• Task: Create dashboard API endpoints

• Implement real-time updates via WebSocket

Credential List Component

• Task: Searchable and filterable credential list
• Create CredentialList.tsx
• Implement data table with sorting and pagination
• Add inline status indicators with color coding
• Create expandable rows for detailed credential information

Search and Filter Panel

• Task: Advanced search and filtering interface
• Create SearchFilter.tsx
• Add text search with autocomplete suggestions
• Implement date range picker for filtering
• Create multi-select status filter dropdown
• Add saved search functionality

Analytics Charts

• Task: Visual analytics and reporting charts

• Add timeline chart for credential processing over time
• Create success rate trends and performance metrics
• Add interactive chart filtering

Export Interface

• Task: Data export and reporting interface
• Create ExportPanel.tsx
• Add export format selection (CSV, PDF, Excel)
• Implement custom date range and filter selection for exports
• Show export progress and download links
• Add scheduled export functionality

Dashboard Features

Key Metrics Display

interface DashboardMetrics {
  totalCredentials: number;
  credentialsSent: number;
  credentialsClaimed: number;
  credentialsExpired: number;
  successRate: number;
  averageClaimTime: number;
  processingRate: number;
}

Status Tracking

enum CredentialStatus {
  UPLOADED = 'uploaded',
  PROCESSING = 'processing',
  GENERATED = 'generated',
  SENT = 'sent',
  DELIVERED = 'delivered',
  OPENED = 'opened',
  CLAIMED = 'claimed',
  EXPIRED = 'expired',
  FAILED = 'failed'
}

Search Filters

interface SearchFilters {
  searchText?: string;
  status?: CredentialStatus[];
  dateRange?: {
    startDate: Date;
    endDate: Date;
  };
  company?: string;
  uploadBatch?: string;
}

API Endpoints

Dashboard Data

GET /api/v1/issuer/dashboard/metrics
GET /api/v1/issuer/dashboard/statistics
GET /api/v1/issuer/dashboard/charts/status-distribution
GET /api/v1/issuer/dashboard/charts/timeline

WebSocket Events

dashboard:metrics-update - Real-time metrics updates
dashboard:credential-update - Individual credential status changes
dashboard:batch-complete - Batch processing completion
dashboard:export-ready - Export file ready for download

Dependencies & Assumptions

Prerequisites

• WebSocket infrastructure setup
• Chart.js or similar charting library
• Export libraries (csv-writer, pdfkit, exceljs)
• Real-time data synchronization

Cross-team Dependencies

• Dashboard UI/UX designs and wireframes
• Export format specifications
• Performance requirements for large datasets

Acceptance Criteria

• Display real-time credential status metrics and statistics
• Search credentials by multiple criteria with autocomplete
• Filter credentials by status, date range, and other attributes
• Export credential data in CSV, PDF, and Excel formats
• Show credential processing timeline and success rates
• Handle large datasets (10,000+ credentials) with pagination
• Provide real-time updates without page refresh
• Support saved searches and custom dashboard views

Estimated Timeline

Week 7: 5 days - Day 1-2: Dashboard data service and API endpoints - Day 3: Search, filter, and export backend services - Day 4-5: Frontend dashboard components and charts

Blockers & Risks

• Risk: Performance with large datasets requiring optimization
• Dependency: WebSocket infrastructure for real-time updates
• Risk: Export generation time for large datasets
• Blocker: Chart library selection and integration
• Risk: Browser memory usage with real-time updates
