MicroFrontends at Scale with Florian Rappl | The Art of Modular Architecture

What if you could build web applications where teams could deploy independently without breaking each other's code? In this episode, we sit down with Florian Rappl—author of "The Art of Micro Frontends," creator of the Piral framework, and Microsoft MVP—to explore how micro frontends are transforming how we build scalable web applications.

Florian shares hard-won lessons from over a decade of building distributed systems, from smart home platforms to enterprise portals for some of Germany's largest companies. We dive deep into the philosophy behind Piral, why modular architecture isn't just about using multiple frameworks, and how micro frontends might be the key to unlocking AI-powered development workflows.

🔸 Key Topics Discussed:

- The evolution from monolithic frontends to true modular architecture

- Why loose coupling is more important than multi-framework support

- How Piral solves the orchestration problem that Module Federation doesn't

- The "inverse dependency" pattern that makes micro frontends resilient

- Building enterprise portals that scale across hundreds of teams

- Server-side rendering and SEO challenges in micro frontend architectures

- Why Cloudflare Workers and edge computing are game-changers for MFEs

- The future of AI-assisted development in modular codebases

- Lessons learned from smart home systems, customer portals, and production deployments

Whether you're an architect evaluating micro frontends for your organization or a developer curious about modular patterns that actually work in production, this conversation offers battle-tested insights you won't find in the documentation.
