Challenge

Executive dashboards are often either too simplistic (a few charts) or too complex (drowning in numbers). The challenge was to build a dashboard that gives executives a clear, actionable view of their business metrics without requiring training or explanation. The dashboard needed to be modular, real-time capable, and extensible — allowing new widgets to be added without restructuring the entire layout.

Approach

I built the dashboard using Next.js 15 with a widget-based architecture. Each metric is a self-contained widget with its own data fetching, loading state, and display logic. The layout uses Base UI's composable components for consistency and accessibility. The design philosophy was "glanceable insights" — every widget should communicate its data within 2 seconds. I used colour coding (green/amber/red) for status indicators, trend arrows for direction, and minimal charting for patterns. Widgets are independently lazy-loaded so underperforming data sources don't block the entire dashboard. The layout supports drag-to-reorder (future feature) and responsive breakpoints that reorganise widgets automatically.

Key Code

// Widget component pattern — self-contained, lazy-loadable
interface WidgetProps {
  title: string;
  refreshInterval?: number;  // seconds
  children: React.ReactNode;
}

function Widget({ title, refreshInterval, children }: WidgetProps) {
  return (
    <div className="bg-white rounded-xl border p-4 shadow-sm">
      <div className="flex items-center justify-between mb-3">
        <h3 className="font-heading font-semibold text-sm">{title}</h3>
        {refreshInterval && (
          <span className="text-xs text-muted">
            Updates every {refreshInterval}s
          </span>
        )}
      </div>
      {children}
    </div>
  );
}

Results

  • Widget-based architecture enables independent development and testing of each metric
  • Glanceable design philosophy reduces cognitive load for executives
  • Responsive layout adapts from mobile (single column) to ultra-wide (4+ columns)
  • Modular data fetching prevents one slow source from blocking the entire view

Key Learnings

  • Widget isolation (independent data loading) is more important than sharing state
  • Skeleton loading states make the dashboard feel fast even when data is slow
  • Design for the 'glance test' — if a widget doesn't communicate in 2 seconds, it needs redesign
