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
