In recent years we have observed great dynamics in web frameworks, which poses major challenges, especially for large and long-lasting enterprise applications. New frameworks come onto the market and others are discontinued almost every day. In order to defuse the short-lived nature of technologies and to be able to react to changes as flexibly as possible, a trend has developed towards small, independent web applications, the so-called micro frontend.

In this talk we would like to give an introduction to the world of micro frontend and address possible integration techniques and challenges. We will introduce the SCION framework, which supports the implementation of a micro frontend-based architecture. SCION was born out of necessity and promises the highest possible isolation with minimal dependency on a framework. Hands-on, we will integrate several example applications using SCION.

Finally, theory meets practice - we share our experiences with micro frontend architectures at SBB using the example of two applications in the areas of sales and planning.
