Ltd.<\/strong> designs and implements production-grade micro-frontend systems, Module Federation pipelines, and scalable enterprise web platforms engineered for maximum velocity, fault tolerance, and organizational autonomy.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Frequently Asked Questions (FAQ)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q1: How does Webpack Module Federation enable micro-frontend architecture?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Module Federation allows a JavaScript application to dynamically import code from another build at runtime over the network. Instead of publishing shared components as npm packages that require recompilation of the host app, Module Federation enables individual micro-frontends to act as independent remotes, exposing modules that the host shell fetches on demand while sharing vendor libraries (like React or Vue) to prevent duplicate downloads.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q2: What is the primary difference between build-time and runtime micro-frontends?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Build-time micro-frontends compile separate packages together at build time (e.g., via npm dependencies inside a monorepo). While simple, this preserves the deployment coupling of a monolith because updating one package requires rebuilding and redeploying the container application. Runtime micro-frontends (using Module Federation or dynamic script injection) load independent builds in the browser or at the edge, achieving true independent deployments.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: How do enterprise micro-frontends manage global state and cross-app communication?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rather than using a single global Redux or Zustand store, best practices recommend keeping state local to each micro-frontend domain. Cross-domain communication is handled via loosely coupled mechanisms: standard browser CustomEvents, a lightweight shared event emitter, or query parameters in the URL route, preventing tight architectural coupling between separate squad codebases.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Modern enterprise software organizations have spent years decomposing backend monoliths into scalable, independently deployable microservices.
