Dashboard Composition Engine

Composes data-rich dashboards from modular widget systems. Handles layout grids, data fetching, real-time updates, and responsive widget reflow.

Decision Framework

When to Apply

Use when: Admin panels, analytics dashboards, monitoring UIs, data-heavy views

When NOT to Apply

Don't use when: Simple data display, single chart, marketing pages

Anti-Patterns

1. Too Many Widgets

Loading 20+ widgets simultaneously causes slow page load and high memory.

2. No Loading States

// BAD: Blank space while loading
<Widget data={data} />

// GOOD: Skeleton loading
{loading ? <WidgetSkeleton /> : <Widget data={data} />}

3. Hardcoded Data

// BAD: Static mock data
const revenue = 125000;

// GOOD: Fetch with error handling
const { data: revenue, error, loading } = useQuery('revenue', fetchRevenue);

Trigger Phrases

• "Build dashboard"
• "Admin panel"
• "Widget layout"
• "Analytics view"
• "Monitoring dashboard"

Patterns

Widget Grid

const DashboardGrid = ({ widgets, layouts }) => (
  <ResponsiveGridLayout layouts={layouts} breakpoints={{ lg: 1200, md: 996, sm: 768 }}>
    {widgets.map(w => (
      <div key={w.id}>
        <WidgetContainer title={w.title} loading={w.loading} error={w.error}>
          <w.component {...w.props} />
        </WidgetContainer>
      </div>
    ))}
  </ResponsiveGridLayout>
);
