Anime
This project is a declarative motion framework and JavaScript animation engine designed to transition CSS properties, SVG attributes, and DOM elements. It provides a comprehensive set of tools for creating complex, multi-part motion sequences by synchronizing animations, timers, and callbacks into a single, unified timeline.
The library distinguishes itself through a robust timeline-based sequence orchestrator that allows for precise timing, label-based control, and hierarchical nesting of animations. It also features a physics-driven interaction library that enables draggable elements with configurable friction, damping, mass, and snapping behavior, facilitating natural user interactions within web applications.
Beyond its core animation capabilities, the framework supports high-performance frame rendering and provides extensive lifecycle hooks for state synchronization. It offers flexible configuration options for easing, units, and playback control, allowing developers to manage complex UI motion through a consistent, object-based parameter interface.
The engine is compatible with standard JavaScript environments and can be integrated into component-based architectures. It is available for installation via package managers, or it can be loaded directly via content delivery networks and import maps for browser-native usage.
