description	BlockNote block-based rich text editor for React. Complete API reference covering useCreateBlockNote, BlockNoteView, all built-in block types, custom block/inline-content/style creation, Editor manipulation API (insertBlocks, removeBlocks, replaceBlocks, updateBlock), format conversion (HTML/Markdown), Slash Menu customization, Formatting Toolbar customization, theming, and real-time collaboration. Use this skill whenever the user's code involves BlockNote, @blocknote/core, @blocknote/react, @blocknote/mantine, @blocknote/shadcn, @blocknote/ariakit, block editors built on ProseMirror/TipTap, useCreateBlockNote, BlockNoteView, BlockNoteEditor, BlockNoteSchema, or any rich-text block editor task in React. Also use when user mentions slash menus, suggestion menus, formatting toolbars, or block-based document structures in a React context. This skill covers the latest BlockNote API. Do NOT search the web for BlockNote docs; use this skill instead.

BlockNote

Documentation source: https://www.blocknotejs.org/docs | Last updated: 2026-03-15

BlockNote is a block-based rich text editor for React, built on ProseMirror and TipTap. Documents are organized into discrete blocks (paragraphs, headings, lists, tables, images, etc.) that can be nested, dragged, and programmatically manipulated.

Installation

npm install @blocknote/core @blocknote/react @blocknote/mantine @mantine/core @mantine/hooks @mantine/utils

UI library alternatives: @blocknote/shadcn (ShadCN), @blocknote/ariakit (Ariakit).

Required CSS imports:

import "@blocknote/core/fonts/inter.css";
import "@blocknote/mantine/style.css"; // or shadcn/ariakit equivalent

Minimal Setup

import "@blocknote/core/fonts/inter.css";
import { BlockNoteView } from "@blocknote/mantine";
import "@blocknote/mantine/style.css";
import { useCreateBlockNote } from "@blocknote/react";

export default function App() {
  const editor = useCreateBlockNote();
  return <BlockNoteView editor={editor} />;
}

Next.js: BlockNote is client-only. Use "use client" directive + dynamic(() => import("./Editor"), { ssr: false }). Disable reactStrictMode for React 19 / Next 15.

Core API Quick Reference

useCreateBlockNote

function useCreateBlockNote(
  options?: BlockNoteEditorOptions,
  deps?: React.DependencyList,
): BlockNoteEditor;

Key options:

• initialContent: PartialBlock[] -- starting document content
• schema: BlockNoteSchema -- custom blocks/inline content/styles
• uploadFile: (file: File) => Promise<string> -- file upload handler
• resolveFileUrl: (url: string) => Promise<string> -- resolve indirect file URLs
• pasteHandler: PasteHandler -- custom paste behavior
• dictionary: Dictionary -- i18n locale object
• collaboration: { provider, fragment, user, showCursorLabels } -- Yjs real-time collab
• domAttributes: Record<string, Record<string, string>> -- custom DOM attrs
• extensions: Extension[] -- custom extensions
• tables: { splitCells?, cellBackgroundColor?, cellTextColor?, headers? } -- table features

BlockNoteView Props

Prop	Type	Description
editor	BlockNoteEditor	Required. Editor instance
editable	boolean	Read-only toggle
onChange	(editor) => void	Content change callback
onSelectionChange	(editor) => void	Selection change callback
theme	"light" | "dark" | Theme | { light: Theme; dark: Theme }	Theme config
formattingToolbar	boolean	Enable/disable default toolbar
slashMenu	boolean	Enable/disable default slash menu
sideMenu	boolean	Enable/disable default side menu
linkToolbar	boolean	Enable/disable default link toolbar
emojiPicker	boolean	Enable/disable default emoji picker

BlockNoteView is uncontrolled -- pass initial content via useCreateBlockNote({ initialContent }), not as a prop.

Document Structure

type Block = {
  id: string;
  type: string;
  props: Record<string, boolean | number | string>;
  content: InlineContent[] | TableContent | undefined;
  children: Block[];
};

type InlineContent = StyledText | Link | CustomInlineContent;

type StyledText = {
  type: "text";
  text: string;
  styles: Styles;
};

type Link = {
  type: "link";
  content: StyledText[];
  href: string;
};

// Default styles
type Styles = Partial<{
  bold: boolean;       // default false
  italic: boolean;     // default false
  underline: boolean;  // default false
  strike: boolean;     // default false
  code: boolean;       // default false
  textColor: string;   // default "default"
  backgroundColor: string; // default "default"
}>;

All blocks share DefaultProps:

type DefaultProps = {
  backgroundColor: string;     // "default"
  textColor: string;           // "default"
  textAlignment: "left" | "center" | "right" | "justify"; // "left"
};

Editor Manipulation Methods

// Reading
editor.document                              // Block[] snapshot
editor.getBlock(id): Block | undefined
editor.getPrevBlock(id): Block | undefined
editor.getNextBlock(id): Block | undefined
editor.getParentBlock(id): Block | undefined
editor.forEachBlock(cb: (block) => boolean, reverse?: boolean): void

// Creating
editor.insertBlocks(blocks: PartialBlock[], ref: BlockIdentifier, placement?: "before" | "after"): void

// Updating
editor.updateBlock(id: BlockIdentifier, update: PartialBlock): void

// Removing
editor.removeBlocks(ids: BlockIdentifier[]): void

// Replacing
editor.replaceBlocks(toRemove: BlockIdentifier[], toInsert: PartialBlock[]): void

// Reordering
editor.moveBlocksUp(): void
editor.moveBlocksDown(): void
editor.canNestBlock(): boolean
editor.nestBlock(): void
editor.canUnnestBlock(): boolean
editor.unnestBlock(): void

// Transactions (group for single undo/redo)
editor.transact(() => { /* multiple operations */ }): void

// Cursor & Selection
editor.getTextCursorPosition(): TextCursorPosition
editor.setTextCursorPosition(target: BlockIdentifier, placement?: "start" | "end"): void
editor.getSelection(): Selection | undefined
editor.setSelection(start: BlockIdentifier, end: BlockIdentifier): void

// Inline Content
editor.insertInlineContent(content: PartialInlineContent): void
editor.getSelectedText(): string
editor.getActiveStyles(): Styles
editor.getSelectedLinkUrl(): string | undefined
editor.addStyles(styles: Styles): void
editor.removeStyles(styles: Styles): void
editor.toggleStyles(styles: Styles): void
editor.createLink(url: string, text?: string): void

// Paste
editor.pasteHTML(html: string, raw?: boolean): void
editor.pasteText(text: string): void
editor.pasteMarkdown(markdown: string): void

// Misc
editor.focus(): void
editor.isFocused(): boolean
editor.undo(): void
editor.redo(): void
editor.isEditable: boolean  // set to toggle read-only
editor.openSuggestionMenu(trigger: string): void

Format Conversion

// Export (lossy)
editor.blocksToHTMLLossy(blocks?: Block[]): string
editor.blocksToMarkdownLossy(blocks?: Block[]): string

// Export (lossless, BlockNote-native HTML)
editor.blocksToFullHTML(blocks?: Block[]): string

// Import
editor.tryParseHTMLToBlocks(html: string): Block[]
editor.tryParseMarkdownToBlocks(markdown: string): Block[]

Best practice: Store documents as JSON.stringify(editor.document) for zero data loss.

Events

editor.onChange((editor, { getChanges }) => { ... }): () => void
editor.onBeforeChange(({ getChanges, tr }) => boolean | void): () => void
editor.onSelectionChange((editor) => { ... }): () => void
editor.onMount(() => { ... }): () => void
editor.onUnmount(() => { ... }): () => void

Change types: "insert", "delete", "update", "move". Each change has a source: "local", "paste", "drop", "undo", "redo", "undo-redo", "yjs-remote".

All event callbacks return cleanup functions.

Custom Schema Creation

import { BlockNoteSchema, defaultBlockSpecs, defaultInlineContentSpecs, defaultStyleSpecs } from "@blocknote/core";

// Method 1: Extend defaults
const schema = BlockNoteSchema.create().extend({
  blockSpecs: { myBlock: MyCustomBlock },
  inlineContentSpecs: { mention: Mention },
  styleSpecs: { font: Font },
});

// Method 2: From scratch (only includes what you specify)
const schema = BlockNoteSchema.create({
  blockSpecs: { ...defaultBlockSpecs, myBlock: MyCustomBlock },
  inlineContentSpecs: { ...defaultInlineContentSpecs, mention: Mention },
  styleSpecs: { ...defaultStyleSpecs, font: Font },
});

const editor = useCreateBlockNote({ schema });

For custom block/inline content/style creation APIs, see references/custom-schemas.md.
