Code Examples

Custom Hook for API Data

interface DashboardData {
  revenue: number;
  orders: number;
  customers: number;
  products: number;
}

const useDashboardData = (): UseApiResult<DashboardData> => {
  const [data, setData] = useState<DashboardData | null>(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState<string | null>(null);

  useEffect(() => {
    fetchDashboardData()
      .then(setData)
      .catch((err) => setError(err.message))
      .finally(() => setLoading(false));
  }, []);

  return { data, loading, error };
};

Reusable Metric Card Component

interface MetricCardProps {
  title: string;
  value: number;
  change: number;
  icon: React.ReactNode;
  format?: "currency" | "number" | "percentage";
}

const MetricCard: React.FC<MetricCardProps> = ({
  title,
  value,
  change,
  icon,
  format = "number",
}) => {
  const formatValue = (val: number) => {
    switch (format) {
      case "currency":
        return new Intl.NumberFormat("en-US", {
          style: "currency",
          currency: "USD",
        }).format(val);
      case "percentage":
        return `${val}%`;
      default:
        return val.toLocaleString();
    }
  };

  return (
    <div className="bg-white dark:bg-gray-800 rounded-lg p-6 shadow-sm">
      <div className="flex items-center justify-between">
        <div>
          <p className="text-sm text-gray-600 dark:text-gray-400">{title}</p>
          <p className="text-2xl font-bold">{formatValue(value)}</p>
        </div>
        <div className="text-blue-500">{icon}</div>
      </div>
      <div className="mt-4">
        <span
          className={`text-sm ${
            change >= 0 ? "text-green-500" : "text-red-500"
          }`}
        >
          {change >= 0 ? "+" : ""}
          {change}%
        </span>
        <span className="text-sm text-gray-500 ml-1">from last month</span>
      </div>
    </div>
  );
};

Performance Optimizations

Code Splitting

• Route-based splitting for faster initial loads
• Component-level splitting for heavy features
• Dynamic imports for chart libraries

Data Management

• Efficient API caching strategies
• Optimistic updates for better UX
• Pagination and virtual scrolling for large datasets

Bundle Optimization

• Tree shaking for smaller bundles
• Webpack optimization for production builds
• Service worker for offline functionality
