React Dashboard

React Dashboard

Use mcp__tdx-studio__render_react. For simple charts, prefer render_chart.

Sandbox Globals

Do NOT import anything — these are pre-loaded:

• React 18: all hooks (useState, useEffect, useMemo, etc.)
• Recharts: all components
• Tailwind CSS: all utility classes
• Theme: isDark (boolean) and theme ("light" / "dark") — reactive, update on toggle

Dark Mode

HTML elements — Tailwind dark: variants:

<div className="bg-white dark:bg-gray-900 text-gray-900 dark:text-gray-100">

Recharts props — isDark ternary:

<XAxis stroke={isDark ? "#9ca3af" : "#6b7280"} />
<Tooltip contentStyle={{ backgroundColor: isDark ? "#1f2937" : "#fff" }} />
<CartesianGrid strokeDasharray="3 3" stroke={isDark ? "#374151" : "#e5e7eb"} />

Example

export default function KPIDashboard({ data }) {
  const { kpis, trend } = data;
  const COLORS = ['#3b82f6', '#10b981', '#f59e0b', '#ef4444'];

  return (
    <div className="p-6 space-y-6 bg-white dark:bg-gray-900 text-gray-900 dark:text-gray-100">
      <div className="grid grid-cols-4 gap-4">
        {kpis.map((kpi, i) => (
          <div key={i} className="p-4 rounded-lg border border-gray-200 dark:border-gray-700">
            <div className="text-sm text-gray-500 dark:text-gray-400">{kpi.label}</div>
            <div className="text-2xl font-bold" style={{ color: COLORS[i] }}>{kpi.value}</div>
          </div>
        ))}
      </div>
      <ResponsiveContainer width="100%" height={300}>
        <LineChart data={trend}>
          <CartesianGrid strokeDasharray="3 3" stroke={isDark ? "#374151" : "#e5e7eb"} />
          <XAxis dataKey="date" stroke={isDark ? "#9ca3af" : "#6b7280"} />
          <YAxis stroke={isDark ? "#9ca3af" : "#6b7280"} />
          <Tooltip contentStyle={{ backgroundColor: isDark ? "#1f2937" : "#fff" }} />
          <Line type="monotone" dataKey="value" stroke="#3b82f6" />
        </LineChart>
      </ResponsiveContainer>
    </div>
