What to fetch

​

Component Guide

​

1. Date Selector / Time Series Navigation

• Filter out items where isOnlyForChartLabel is true (these entries are used for chart axis labeling in future & past data points when there is no daily summary for those dates)

• timestamp - Unix timestamp in milliseconds for the date
• isOnlyForChartLabel - Boolean flag to identify chart-label-only entries

​

2. Portfolio Value Cards

• portfolio object from the selected daily summary item

​

Total Account Value Card

• portfolio.total.displayValue - Formatted value string (e.g., “€12,345.67”)
• portfolio.total.value - Numeric value in cents

​

Holdings Card

• portfolio.holdings.displayValue - Formatted investment value
• portfolio.holdings.upBy - Percentage increase (if positive)
• portfolio.holdings.downBy - Percentage decrease (if negative)

​

Savings Card

• portfolio.savings.displayValue - Formatted savings value
• portfolio.savings.dailyInterest - Daily interest earned (if applicable)

• Show up/down indicators with appropriate colors (green for up, red for down)
• Cards should be swipeable/scrollable
• Default selection should be “Total” (index 0)

​

3. Portfolio Chart

• Use the entire data array from the response
• Filter based on selected portfolio type (Total, Holdings, Savings, or Cash)

​

For Total Account Value:

• Iterate through all items in data array
• Use data[].portfolio.total.chartValue - Numeric value for chart plotting
• Use data[].timestamp - For sorting and date handling
• Use data[].portfolio.total.displayValue - Tooltip/display value on hover
• X-axis Labels: Generate labels from timestamp field

​

For Holdings:

• data[].portfolio.holdings.chartValue
• data[].timestamp
• data[].portfolio.holdings.displayValue

​

For Savings:

• data[].portfolio.savings.chartValue
• data[].timestamp
• data[].portfolio.savings.displayValue

​

For Cash:

• data[].portfolio.cash.chartValue
• data[].timestamp
• data[].portfolio.cash.displayValue

• maxValueDifferences.total - Maximum value difference for Total (used for chart scaling)
• maxValueDifferences.holdings - Maximum value difference for Holdings
• maxValueDifferences.savings - Maximum value difference for Savings

• Chart should update when user selects a different portfolio card type
• Chart should highlight the currently selected date

• Chart should be interactive, allowing users to tap/click on data points to select that date
• Chart Label Handling: For items where isOnlyForChartLabel is true, generate labels from timestamp for x-axis display
• Filter out chart-label-only points when allowing date selection, but include them in chart rendering for proper axis labels

Data Flow

1. Initial Load:
   • Fetch data from GET /daily-summaries endpoint with x-user-id header
   • Filter data array to remove items where isOnlyForChartLabel is true
   • Select the most recent date (last item in filtered array) as default
   • Render all components using data from the selected date
2. Date Selection:
   • When user selects a different date from the date selector
   • Update all components with data from the newly selected daily summary item
   • Update chart highlight to show selected date
   • Maintain selected portfolio card type (Total/Holdings/Savings/Cash)
3. Portfolio Card Selection:
   • When user selects a different portfolio card (Total/Holdings/Savings/Cash)
   • Update chart to show data for the selected portfolio type
   • Use corresponding maxValueDifferences value for chart scaling
   • Update chart data points using the appropriate portfolio.*.chartValue fields
4. Refresh:
   • Re-fetch from GET /daily-summaries endpoint
   • Update all components with fresh data
   • Maintain current date and portfolio card selection if still valid

​

Error Handling

• If the API request fails, display an appropriate error message
• If data array is empty or null, show an empty state
• If specific fields are missing (e.g., portfolio, performers), hide the corresponding components gracefully
• Handle cases where historical data might be incomplete
• Always check if optional fields exist before accessing nested properties (especially performers, sentimentScore, todayMarkets, marketSummary)

​

Performance Considerations

• The data array may contain many items (potentially weeks or months of data)
• Consider pagination or limiting the number of data points if the array becomes very large
• Cache the response appropriately to avoid unnecessary API calls
• Filter isOnlyForChartLabel items early to reduce processing overhead
• Use maxValueDifferences values to optimize chart rendering
• Generate date labels efficiently using cached formatters

Example: Complete Fetch Implementation

const BASE = 'https://api.wealthyhood.com';

async function fetchHomeScreen({ token, userId }) {
  const headers = {
    'Authorization': `Bearer ${token}`,
    'x-user-id': userId,
    'Accept': 'application/json'
  };

  const response = await fetch(`${BASE}/daily-summaries`, { headers });
  
  if (!response.ok) {
    throw new Error(`Failed to fetch daily summaries: ${response.status}`);
  }

  const data = await response.json();
  
  // Filter out chart-label-only entries for date selector
  const selectableDates = data.data.filter(
    item => !('isOnlyForChartLabel' in item && item.isOnlyForChartLabel)
  );
  
  // Get most recent date (last item)
  const selectedDate = selectableDates[selectableDates.length - 1];
  
  // Generate date labels client-side
  const formatDateLabel = (timestamp) => {
    const date = new Date(timestamp);
    const today = new Date();
    const isToday = date.toDateString() === today.toDateString();
    
    if (isToday) return 'Today';
    
    return date.toLocaleDateString('en-GB', { 
      day: 'numeric', 
      month: 'short' 
    });
  };
  
  return {
    ...data,
    selectableDates: selectableDates.map(item => ({
      ...item,
      dateLabel: formatDateLabel(item.timestamp)
    })),
    selectedDate: {
      ...selectedDate,
      dateLabel: formatDateLabel(selectedDate.timestamp)
    }
  };
}

curl -X GET 'https://api.wealthyhood.com/daily-summaries' \
  -H 'Accept: application/json' \
  -H 'Authorization: Bearer YOUR_ACCESS_TOKEN' \
