ReactFlow Mindmap: Building Interactive Knowledge Maps with ReactFlow

ReactFlow Mindmap

ReactFlow Mindmap transforms the traditional mind mapping experience into an interactive, web-based tool powered by ReactFlow. This powerful example demonstrates how to create beautiful, functional mind maps that go beyond static diagrams, offering real-time editing, collaboration capabilities, and seamless integration with modern web applications.

What is a Mind Map?

A mind map is a visual diagram used to organize information hierarchically around a central concept. It uses a non-linear graphical structure that allows you to capture thoughts, ideas, and information in a way that reflects how your brain naturally works.

Traditional mind maps are static, but ReactFlow enables:

Interactive editing: Add, remove, and reorganize nodes in real-time
Dynamic layouts: Automatic positioning with manual override options
Rich content: Text formatting, images, and links within nodes
Collaboration: Real-time updates for team brainstorming sessions
Export options: Save and share your mind maps in multiple formats

Key Features

Hierarchical Structure

Build tree-like mind map structures with:

Central node: The main topic or concept at the center
Primary branches: Major themes radiating from the center
Secondary branches: Sub-topics extending from primary branches
Tertiary branches: Further details and sub-points

The hierarchical structure makes it easy to:

See relationships between ideas
Organize complex information
Expand and collapse branches
Navigate large knowledge structures

Drag & Drop Interface

Intuitive drag-and-drop functionality allows you to:

Reposition nodes: Move ideas to different branches easily
Reorganize structure: Change the hierarchy by dragging nodes
Merge branches: Combine related concepts
Split nodes: Break down complex ideas into smaller parts

The drag-and-drop interface makes mind mapping feel natural and fluid, encouraging creative thinking and spontaneous idea generation.

Rich Text Editing

Edit node content with comprehensive formatting options:

Bold and italic: Emphasize important points
Lists: Create bulleted or numbered lists within nodes
Links: Add hyperlinks to external resources
Colors: Highlight text with different colors
Font sizes: Adjust text size for hierarchy

Rich text editing transforms simple nodes into comprehensive information containers.

Custom Themes

Choose from multiple color themes or create your own:

Professional themes: Clean, business-appropriate color schemes
Creative themes: Vibrant colors for brainstorming sessions
Minimal themes: Simple, distraction-free designs
Custom themes: Match your brand or personal preferences

Themes can be applied globally or customized per branch for visual organization.

Export Options

Export your mind maps in multiple formats:

PNG: High-resolution images for presentations
SVG: Scalable vector graphics for web and print
PDF: Professional documentation format
JSON: Machine-readable format for backup and import

Export capabilities ensure your mind maps can be shared, printed, or integrated into other tools.

Implementation Details

Node Structure

Each mind map node contains:

interface MindMapNode {
  id: string;
  type: 'central' | 'branch' | 'leaf';
  content: string;
  level: number; // Distance from center
  parentId?: string;
  children: string[]; // Child node IDs
  position: { x: number; y: number };
  style: {
    backgroundColor: string;
    borderColor: string;
    fontSize: number;
  };
}

Automatic Layout

The layout algorithm automatically positions nodes:

// Example: Automatic layout calculation
function calculateLayout(centralNode, nodes) {
  const branches = nodes.filter(n => n.parentId === centralNode.id);
  const angleStep = (2 * Math.PI) / branches.length;
  
  branches.forEach((branch, index) => {
    const angle = index * angleStep;
    const radius = 200; // Distance from center
    branch.position = {
      x: centralNode.position.x + radius * Math.cos(angle),
      y: centralNode.position.y + radius * Math.sin(angle),
    };
    
    // Recursively position children
    positionChildren(branch, nodes, angle);
  });
}

Rich Text Editor Integration

Integrate a rich text editor for node content:

// Example: Rich text editor component
import { Editor } from 'rich-text-editor';

const NodeEditor = ({ node, onUpdate }) => {
  return (
    <Editor
      value={node.content}
      onChange={(content) => onUpdate(node.id, { content })}
      placeholder="Enter your idea..."
      toolbar={['bold', 'italic', 'list', 'link']}
    />
  );
};

Best Practices

Central Concept

Keep it focused: The central node should represent a single, clear concept
Use keywords: Short, descriptive keywords work best
Make it prominent: The central node should be visually distinct

Branch Organization

Limit primary branches: 5-7 main branches work best for readability
Use keywords: Keep branch labels short and descriptive
Maintain hierarchy: Keep related ideas grouped together
Balance branches: Try to distribute content evenly

Visual Design

Use colors strategically: Different colors for different branches
Maintain consistency: Use consistent styling within branches
Keep it readable: Ensure sufficient contrast and font sizes
Avoid clutter: Don't overcrowd nodes with too much information

Content Organization

One idea per node: Keep nodes focused on single concepts
Use hierarchy: Organize information from general to specific
Add details gradually: Start with main ideas, add details later
Review and refine: Regularly review and reorganize your mind map
