The Path To A Declaratively Animated Future
summary
Claim: imperative animation is too brittle for most UI work so a declarative layer simplifies it. Built a CSS-like library called Pose on top of engines like Popmotion, with features such as automatic transitions, independent transform axes, and parent-driven staggering via context. Examples: hover springs, coordinated sidebar enter/exit with staggered children, and an opinionated transform order. Prototype works in demos and enables middleware to swap engines or apply global characteristics. Development timeline: four years of work, Pose released six months earlier.
