Usage

import { Schema, defaultNodes, defaultMarks } from '@trevixal/core'
import { useEditor, useEditorSnapshot, EditorContent } from '@trevixal/react'

const schema = new Schema({ nodes: defaultNodes(), marks: defaultMarks() })

function Bold({ editor }) {
  // Reference-stable snapshot: this re-renders when the toolbar state
  // changes, and never on plain typing.
  const snapshot = useEditorSnapshot(editor)
  return (
    <button
      aria-pressed={snapshot?.activeMarks.includes('bold')}
      onClick={() => editor.commands.toggleMark('bold')}
    >
      Bold
    </button>
  )
}

export function Editor() {
  const editor = useEditor({ schema })
  return (
    <div className="trevixal">
      <Bold editor={editor} />
      <EditorContent editor={editor} placeholder="Write something…" />
    </div>
  )
}

Typing does not re-render your tree

The editor's DOM lives outside React's reconciliation, React mounts an empty container and the view owns what is inside it (ADR-0007). Toolbars subscribe to snapshots through useSyncExternalStore, so a keystroke re-renders only the components whose state actually changed. A test asserts that a sibling which does not subscribe renders zero times while typing.

React components inside the document

import type { NodeViewProps } from '@trevixal/react'

function Counter({ node, updateAttributes }: NodeViewProps) {
  return <button onClick={() => updateAttributes({ count: Number(node.attrs.count) + 1 })}>
    {String(node.attrs.count)}
  </button>
}

<EditorContent editor={editor} nodeViews={{ counter: Counter }} />
Copy

Node views render through portals, so they are ordinary React components with hooks, context and all, and their clicks dispatch real editor transactions.

Exports

useEditor, useEditorSnapshot, EditorContent, EditorProvider, useCurrentEditor, and the EditorContentProps / NodeViewProps types.
