Showkase: Automated UI Infrastructure in Jetpack Compose using KSP

This talk explores how Airbnb built and open-sourced Showkase, an annotation-processor-based Android library that leverages Kotlin Symbol Processing (KSP) to organize, discover, and visualize Jetpack Compose UI elements. It addresses challenges like component discoverability and the manual maintenance of design system browsers. The presentation delves into Showkase's internals, how it processes annotations to generate metadata, and its integration with tools like Paparazzi for automated screenshot testing. The talk also touches upon extending Showkase to support styles, colors, and typography.
