Motion
Motion is a declarative animation framework designed for Vue applications. It provides a system for defining complex visual states and element transformations through an object-based syntax, allowing developers to manage interface motion directly within component templates.
The library distinguishes itself by utilizing a physics-driven engine that calculates frame-by-frame values using spring-based mathematical models. This approach enables natural movement and fluid transitions between visual states without the need for manual keyframe management. By leveraging a fine-grained reactivity system, the framework synchronizes property changes with visual updates, ensuring that animations remain consistent with the underlying component state.
The system covers a broad range of motion design patterns, including viewport-triggered effects, interactive feedback for user inputs, and automated lifecycle orchestration for entry and exit sequences. It handles the normalization of geometric properties to ensure consistent rendering across different browser environments. The project is distributed as a collection of composables and directives that integrate into the standard Vue component lifecycle.
