Enhance Dashboard with Real-Time Data and Analytics

[Dark-Developer93]

Description

Improve the dashboard by integrating real-time data from the database, implementing advanced analytics, and adding interactive charts. This enhancement will provide more meaningful insights and allow users to filter data based on selected date ranges.

Features to Implement

1. Fetch real-time data for leave statistics, user counts, upcoming events, and balance additions.
2. Implement data filtering based on the selected date range from MonthDateRangePicker.
3. Add interactive charts to visualize trends and patterns.
4. Create a new analytics table in the database to store aggregated data.
5. Implement server-side data aggregation for improved performance.

Technical Tasks

1. Update Prisma schema to include a new Analytics model.
2. Modify the dashboard page to fetch real-time data from the server.
3. Implement server-side actions to aggregate and filter data based on date range.
4. Integrate a charting library (e.g., Chart.js or Recharts) for data visualization.
5. Update StatsCards component to display real data and handle date range changes.
6. Implement data caching mechanism to improve performance.

Database Schema Updates

Add the following model to the Prisma schema:

model Analytics {
    id String @id @default(cuid())
    date DateTime
    totalLeaves Int
    totalUsers Int
    upcomingEvents Int
    balancesAdded Int
}

File Updates

1. Update dashboard page:

   • app/(dashboard)/dashboard/page.tsx

2. Modify StatsCards component:

   • app/(dashboard)/dashboard/StatsCards.tsx

3. Update MonthDateRangePicker to emit selected date range:

   • app/(dashboard)/dashboard/MonthDateRangePicker.tsx

4. Create a new file for server actions:

   • app/actions/analyticsActions.ts

Implementation Details

1. Implement server-side data aggregation in analyticsActions.ts.
2. Use React Query or SWR for efficient data fetching and caching.
3. Integrate Chart.js or Recharts for creating interactive charts.
4. Implement useEffect in the dashboard page to fetch data when date range changes.
5. Update StatsCards to receive and display real-time data.

Acceptance Criteria

• Dashboard displays real-time data fetched from the database.
• Users can filter data by selecting a date range using MonthDateRangePicker.
• StatsCards show accurate statistics based on the selected date range.
• Interactive charts are implemented to visualize trends.
• The system performs efficiently with large datasets.

Additional Considerations

• Implement proper error handling for data fetching and processing.
• Ensure responsive design for charts and stats cards.
• Consider implementing data export functionality for reports.

Required Libraries

• Chart.js or Recharts for data visualization
• React Query or SWR for efficient data fetching

Please update the mentioned files and create any new necessary files to fully integrate these enhancements into the dashboard.
