Introduction - Yoopta Editor (Beta)

Motivation. Why Yoopta?

Beta Yoopta is fully open source and built with all my heart and love. It was born from real pain I’ve integrated rich-text editors into products more times than I’d like to admit. Every time it was the same story: wrestling with complex APIs, fighting against opinionated UI that doesn’t fit your product, hacking around limitations. Yoopta was built to end that cycle. The idea is simple: give developers a headless core when they need full control, but also ship 20+ ready-made plugins, pre-built UI components (toolbars, slash menus, block actions), and theme presets (shadcn, Material) — so you can launch a polished editing experience without thinking about implementing a rich-text editor in your project and engage in other business tasks. If Yoopta saves you time, consider starring the repo or sponsoring the project. It keeps the project alive.

Architecture Overview

Headless Core

Yoopta Editor is headless by design. The core package (@yoopta/editor) provides all the logic for managing content, blocks, elements, and operations, but doesn’t render any UI. This means:

You have complete control over the visual appearance
You can build custom UI components that fit your design system
The editor logic is framework-agnostic (though currently React-only)
But (!!!) Yoopta also provides pre-built theme presets for each plugin so you can get a full editing experience and start quickly (shadcn theme is available now; Material theme is in progress)
Yoopta also provides pre-built UI components via @yoopta/ui (toolbars, menus, block actions etc.) so you can improve the editing experience without building everything from scratch

Themes

Themes provide pre-styled element components that make it easy to get started:

@yoopta/themes-shadcn - Shadcn UI styled components (production ready)
@yoopta/themes-material - Material Design styled components (in development)

Themes use helper functions like applyTheme() to automatically apply styled components to your plugins.

UI Components Package

The @yoopta/ui package provides ready-to-use React components for common editor features:

Toolbar - Text formatting toolbar
ActionMenuList - Block insertion menu (slash command menu)
SlashCommandMenu - Inline command menu
BlockOptions - Block-level action menu
FloatingBlockActions - Floating action buttons
HighlightColorPicker - Color picker for text highlighting
Portal & Overlay - Utility components for rendering outside DOM

These components are unstyled and can be customized to match your design.

Core Concepts

Slate Per Block

Yoopta Editor uses a unique architecture where each block has its own Slate.js editor instance. This means:

Each block is an independent Slate editor
Blocks don’t share selection state
Operations on one block don’t affect others
Better performance for large documents

// Each block has its own Slate editor
editor.blockEditorsMap = {
  'block-1': SlateEditor, // Paragraph block
  'block-2': SlateEditor, // Heading block
  'block-3': SlateEditor, // Table block
  // ...
};

Block Structure

A block in Yoopta Editor consists of:

Block Data - Metadata and content
Slate Value - The Slate.js document structure
Element Tree - Hierarchical structure of elements

type YooptaBlockData = {
  id: string; // Unique block identifier
  type: string; // Plugin type (e.g., 'Paragraph', 'Heading')
  value: SlateElement[]; // Slate document structure
  meta: {
    order: number; // Display order
    depth: number; // Nesting depth
    align?: 'left' | 'center' | 'right';
  };
};

Element Tree

Each block contains a tree of elements. Elements can be:

Root Elements - Top-level element in a block
Container Elements - Elements that contain other elements
Leaf Elements - Elements that contain only text nodes

Example - Table Block Structure:

table (root)
  └── table-row
      ├── table-data-cell (leaf)
      ├── table-data-cell (leaf)
      └── table-data-cell (leaf)

Example - Steps Block Structure:

step-container (root)
  ├── step-list
  │   └── step-list-item
  │       ├── step-list-item-heading (leaf)
  │       └── step-list-item-content (container)
  │           └── [injected elements from other plugins]
  └── step-list-item-content (container)
      └── [injected elements from other plugins]

Editor Value Structure

The editor value (YooptaContentValue) is a record (object) where keys are block IDs and values are block data:

type YooptaContentValue = Record<string, YooptaBlockData>;

// Example value structure:
{
  "block-1": {
    id: "block-1",
    type: "Paragraph",
    value: [
      {
        id: "element-1",
        type: "paragraph",
        children: [{ text: "Hello, world!" }]
      }
    ],
    meta: {
      order: 0,
      depth: 0,
      align: "left"
    }
  },
  "block-2": {
    id: "block-2",
    type: "Heading",
    value: [
      {
        id: "element-2",
        type: "heading-one",
        children: [{ text: "Introduction" }]
      }
    ],
    meta: {
      order: 1,
      depth: 0
    }
  }
}

injectElementsFromPlugins

The injectElementsFromPlugins property allows elements from one plugin to be inserted inside elements of another plugin. This enables nested content structures. Example - Callout with nested content:

import Callout from '@yoopta/callout';
import Lists from '@yoopta/lists';
import Blockquote from '@yoopta/blockquote';
import Image from '@yoopta/image';
import Code from '@yoopta/code';
import Tabs from '@yoopta/tabs';

const plugins = [
  Callout.extend({
    injectElementsFromPlugins: [
      Lists.BulletedList,
      Lists.NumberedList,
      Lists.TodoList,
      Blockquote,
      Code,
    ],
  }),
  Tabs.extend({
    injectElementsFromPlugins: [Code],
  }),
];

When a user is inside a callout element, the slash command menu will only show blocks from the injected plugins. Use Cases:

Callout blocks - Allow paragraphs, lists, and headings inside
Table cells - Allow any block type inside cells
Steps content - Allow nested content in step items
Accordion items - Allow nested blocks inside accordion content
Tab items - Allow nested blocks inside tab leaf elements

How it works:

When the cursor is inside an element with injectElementsFromPlugins
The slash command menu filters available blocks to only those specified
Inserted blocks become children of that element

Plugin System

Plugin Structure

A plugin defines:

Type - Unique identifier (e.g., ‘Paragraph’, ‘Table’)
Elements - Element tree structure with render functions
Commands - Custom operations for the plugin
Options - Plugin-specific configuration
Lifecycle - Hooks for plugin initialization
Events - Keyboard and interaction handlers
Extensions - Slate.js editor extensions

Example Plugin:

const Paragraph = new YooptaPlugin({
  type: 'Paragraph',
  elements: <paragraph render={ParagraphRender} />,
  commands: ParagraphCommands,
  options: {
    display: {
      title: 'Paragraph',
      description: 'Start writing with plain text',
    },
  },
});

Element Definition

Elements define the structure and rendering:

<element-type
  render={Component} // React component to render
  props={defaultProps} // Default element properties
  asRoot={true} // Mark as root element
  children={['child-type']} // Allowed child element types
  injectElementsFromPlugins={[]} // Allowed plugins for nested content
  placeholder="Type something..." // Placeholder text
/>
