## What it is
Stage.js is a lightweight 2D rendering and layout library for building HTML5 Canvas games in JavaScript/TypeScript. It provides an optimized rendering loop, pointer event dispatching, texture atlases, and a component tree model with layouts and transitions.

## Use cases
- build a 2d html5 canvas game
- create interactive graphics in the browser
- make a cross-platform mobile web game
- render sprites with texture atlases
- handle pointer/touch events on game components
- animate and layout 2d game scenes

## When to choose
- you want a lightweight 2D canvas game engine without heavy dependencies
- you need simple layout, transitions, and pointer event handling for 2D games
- you target both desktop and mobile browsers from one codebase

## When to avoid
- you need 3D rendering or WebGL features
- you want a full-featured engine with physics, audio, and asset pipelines built in
- you need native mobile or desktop app packaging

## Facets
- artifact type: library
- maturity: active
- function: graphics, animation, ui-components
- domain: web-development, graphics
- platform: browser, cross-platform
- tags: 2d-canvas, html5-games, rendering-engine, sprite-atlas, game-layout, game-development, javascript, mobile
