Animator Core is the runtime and rendering engine for Haiku Animator and the components you create with Animator. This engine is a dependency for any Haiku Animator components that are run on the web.

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 c

Velocity is a JavaScript animation library used to create high-performance CSS and SVG animations. It functions as a CSS property interpolator and a spring physics engine, enabling the creation of smooth visual transitions and organic movement for web elements. The project provides a programmatic interface for modifying vector attributes and 3D transformations through its SVG animation framework. It further distinguishes itself as an animation sequence orchestrator, allowing for the chaining of movements and the staggering of start times across multiple elements using promises. The library c

This project is a client-side library for rendering responsive, animated SVG progress indicators. It functions as a frontend UI component and vector animation library designed to visualize completion status through linear, circular, and radial shapes. The library is distinguished by its support for custom vector path geometries, allowing users to define specific SVG path data to create specialized shapes. It uses a vector-based rendering approach to ensure that indicators remain sharp across different screen resolutions. The tool covers a range of capabilities including both static and anima

CSS animations engine

This project is a declarative animation library and high-performance engine designed for creating fluid, interactive vector motion graphics on the web. It provides a specialized framework for defining, rendering, and orchestrating complex visual sequences, including custom geometric shapes and dynamic property transitions. The library distinguishes itself through a robust particle system framework that generates explosive or organic visual effects by emitting multiple shapes with randomized trajectories and paths. It utilizes a master timeline controller to synchronize independent animation i

move.js is a JavaScript motion engine and CSS3 animation framework designed to animate DOM elements. It functions as a DOM animation library that changes visual element properties and colors over time. The library serves as a CSS bezier easing controller, using cubic-bezier curves to manage animation acceleration and deceleration. It enables sequential motion design, allowing multiple visual steps to execute in a specific order. The framework covers the animation of element properties such as position, rotation, scale, skew, and colors. It provides capabilities for UI component transitions a
