## What it is
mo.js is a JavaScript motion graphics library for the web providing a fast, retina-ready, declarative API for animations. It ships built-in components like Html, Shape, Swirl, Burst, and Stagger, plus companion editor tools for crafting motion effects.

## Use cases
- add delightful micro-interactions and animations to a website
- create SVG shape animations like bursts and swirls
- build declarative motion graphics timelines for the web
- animate HTML elements with a modular lightweight library
- craft retina-ready screen-density-independent effects
- integrate motion graphics into React apps

## When to choose
- you need a declarative, modular animation library focused on motion graphics and shapes
- you want lightweight, retina-ready effects without heavy file-size overhead
- you need built-in components like Burst, Swirl, and Stagger out of the box

## When to avoid
- you need general-purpose full app state or UI framework features beyond animation
- you require complex 3D or WebGL-based animation
- you need a CSS-only or keyframe-based simple transition solution

## Facets
- artifact type: library
- maturity: active
- function: animation, graphics, ui-components
- domain: web-development, frontend, graphics
- platform: browser
- tags: motion-graphics, svg, declarative-api, web-animation, micro-interactions, nodejs, javascript
