Lesson 7 : Micro-Frontends Explained: Monolith vs Module Federation

Visit our website : https://systemdrd.com/ Course Link: https://frontendeng.substack.com/ Learn how to build and understand micro-frontends by comparing a traditional monolith with a federated frontend architecture. In this lesson, you’ll create a shared mount(el) entry for Billing and Analytics, compose applications at build time with a monolith, and load remote applications at runtime with a federated shell. You’ll also learn Module Federation concepts, micro-frontend architecture, runtime loading, independent deployments, version contracts, import maps, remote entries, and application boundaries while building a real working example. See how micro-frontends handle version mismatches, deployment gates, CI validation, runtime checks, fallbacks, and deployment failures without taking down the entire application. The Control Tower provides a live deployment topology showing remote versions, expected version ranges, Turbo rebuilds, and federation status. This tutorial also demonstrates the trade-offs between monoliths and micro-frontends and explains when federation is actually worth the added complexity. #MicroFrontends #ModuleFederation #FrontendArchitecture #WebDevelopment #JavaScript
