## What it is
Eva.js is a front-end 2D game engine built on an Entity-Component-System architecture with a PixiJS-powered rendering pipeline. It ships as a lightweight core plus modular plugins for rendering, animation, physics, sound, and interaction, targeting web and WeChat minigame projects.

## Use cases
- build interactive 2D games in the browser
- create WeChat minigames
- make casual games like merge or card games for web
- add sprite and spine animations to a web page
- develop marketing mini-games for e-commerce apps
- prototype 2D games with an ECS engine in JavaScript

## When to choose
- you need a lightweight, plugin-based 2D engine for web or minigame targets
- you want ECS architecture with out-of-box components for images, text, animation, and physics
- your project uses PixiJS-style WebGL/Canvas rendering with Spine, DragonBones, or Lottie assets

## When to avoid
- you need 3D rendering or a full-featured native game engine
- you are building a non-game app where a general UI framework fits better
- you require console/PC native deployment

## Facets
- artifact type: framework
- maturity: active
- function: game-engine, graphics, animation, ui-components
- domain: web-development, frontend, graphics
