What is Micro-Frontend architecture, and why does React suit it?

Micro-Frontend architecture breaks a large web app into smaller, independent frontend modules managed by different teams. Each micro-frontend handles a distinct feature or section of the app, improving modularity and scalability.

React suits Micro-Frontends well because its component-based nature allows seamless integration of independently built UI pieces. React’s flexibility supports team autonomy, parallel development, and dynamic loading of micro frontends, which accelerates deployment and enhances performance.

Code

const MicroApp = React.lazy(() => import('micro-app/Widget'));

function HostApp() {
  return (
    <React.Suspense fallback={<div>Loading...</div>}>
      <MicroApp />
    </React.Suspense>
  );
}
