How to track and guide the Design System adoption in React and React Native

We first implemented the Design System Visual Coverage to track the design system impact on users' devices, coloring the pixels during navigation without impacting the UX.

We then implemented a more classic static analysis system and dashboard, to have earlier feedback on what the Product teams are doing in terms of using the design system.

I will present our experience to show engineers, designers, and company leaders the measurable value of the Design System in our products at Preply, a language learning platform with ~50M lessons taken per year.
