A block-based rich text editor for React, Mina Rich Editor provides integrated AI content generation, real-time collaboration, and a flexible extension system. It aims to equip modern applications with advanced features out-of-the-box, reducing the burden on developers to build these complex functionalities themselves.

How It Works

The editor utilizes a block-based architecture for structured content creation. AI integration streams LLM output (from OpenAI, Anthropic, Gemini, Ollama, or custom endpoints) directly into editor blocks, supporting token-by-token streaming and AI-powered text editing/formatting on highlighted selections. Real-time collaboration is managed by Y.js, employing Conflict-Free Replicated Data Types (CRDTs) for seamless multi-user editing and live cursor presence. A TipTap-inspired extension API allows developers to create custom blocks, marks, and commands as plain objects, building upon 22 built-in extensions. Performance is optimized via per-block subscriptions and O(1) lookups in a flat node map, minimizing re-renders and keystroke overhead.

Highlighted Details

• AI Content Generation: Provider-agnostic LLM integration with token-by-token streaming into structured blocks. Supports AI selection editing (rephrase, grammar) and AI-powered formatting.
• Real-Time Collaboration: Powered by Y.js CRDTs for conflict-free merging, live cursor presence, and WebSocket provider support.
• Extension System: TipTap-inspired API for custom block types (Node.create), inline marks (Mark.create), and commands (Extension.create), featuring 22 built-in extensions.
• Performance: Engineered for zero-lag editing at any document size, with per-block subscriptions, O(1) lookups, and operation-based undo/redo, claiming ~2.8ms overhead per character typed.
• Features: Notion-style blocks (paragraphs, lists, tables, code), Markdown shortcuts, smart paste, two editor modes (full/compact), export to JSON/semantic HTML/Markdown, 3 theme presets (Notion, Minimal, GitHub), WCAG 2.1 AA accessible, TypeScript-first.
