In the last year new frameworks arrived or gained some fame making use of the islands architecture, a paradigm that aims to reduce the volume of JavaScript shipped through "islands" of interactivity that can be independent delivered on top of otherwise static HTML. Many people started to confuse this pattern with micro frontends - which is all about scaling development of a web application. Now, we have two patterns - one to scale the performance of a website and another one to scale the development. It turns out - they are not mutually exclusive. In this talk micro frontend expert Dr. Florian Rappl will introduce both architectural styles and show how they can be combined to create outstanding web experiences that scale not only in development, but also in usage.
