Microfrontends the right way

Microfrontends promise independent deployments and team autonomy but often introduce unnecessary complexity. While the concept addresses organizational challenges more than technical ones, several implementation approaches exist: iframes provide hard isolation but poor UX, web components offer framework-agnostic custom elements with shadow DOM, single-spa adds orchestration layers that create distributed system complexity, and Webpack's module federation enables runtime code sharing. Modern browsers support native ES modules for cross-domain imports, potentially reducing bundler dependency. Astro's island architecture emerges as a practical solution, loading UI components only when needed.
