Micro Frontends Workspace

Learn how large frontend teams split monolithic frontend applications into independently built, deployed, and owned micro applications using shell architecture, runtime composition, Module Federation, shared contracts, and isolated release pipelines. Select checklist cards, explore sequence flowcharts, configure federation plugins, build capstones, and run active-recall simulators.
