## What it is
RoosterJs is a framework-independent JavaScript rich text editor built by Microsoft, contained within a single HTML div element. It operates on a middle-layer 'Content Model' data structure and is organized into modular packages for core editing, APIs, DOM operations, and plugins.

## Use cases
- embed a rich text editor in a web app
- build a custom WYSIWYG editor without a framework dependency
- add formatted text editing to a comment or email composer
- convert between markdown and rich text content
- customize editor behavior with plugins

## When to choose
- you need a framework-agnostic rich text editor
- you want fine-grained control over editor content via a structured content model
- you need modular packages to build a tailored editing experience

## When to avoid
- you need a full-featured out-of-the-box editor with minimal setup
- your project requires a React-specific editor ecosystem
- you need mobile-native text editing

## Facets
- artifact type: library
- maturity: active
- function: editor, ui-components, plugin-system, markdown
- domain: web-development, frontend, text-editors, developer-tools
- platform: browser, cross-platform
