Manejo de Carga con Suspense
Suspense es un componente de React que te permite "esperar" a que algún código se cargue dinámicamente y mostrar un indicador de carga mientras tanto. Es comúnmente usado junto con React.lazy para implementar lazy loading de componentes, pero también puede ser útil para otras operaciones asíncronas como la obtención de datos.
Uso de Suspense para mostrar un fallback:
{`import React, { lazy, Suspense } from 'react';
const OtroComponenteLazy = lazy(() => import('./OtroComponenteLazy'));
function Dashboard() {
return (
Panel de Control
Cargando panel...}>
);
}
export default Dashboard;`}
El prop fallback de Suspense acepta cualquier elemento de React que desees mostrar mientras se carga el componente diferido. Esto proporciona una experiencia de usuario más fluida.
