Editor compatibility

Layer：Shared document capability

Editor	Status	Assembly and boundaries
Classic	Supported	classicEditorPreset — Use the product-neutral classicEditorPreset without duplicating installed capabilities. The Word preset replaces paragraphs, headings and container lists; do not stack generic structures onto that model.
Block	Supported	createBlockEditorPreset — The default createBlockEditor preset installs this capability. Configure the corresponding preset child; graphic editing uses the preset's workspace ports, while persistence and assets remain host-owned. Avoid duplicate extensions.

“Supported” means the product assembly above exists; interaction, host services and file formats retain their own conditions. See status and integration rules. Licensing is shown separately.

Installation

pnpm add @quirekit/extensions@alpha

Install in Editor extensions. The host supplies a view, container and persistence; see Quick start.

import { Formatting } from '@quirekit/extensions'

Use compatible versions available from your distribution source. This site uses the Alpha workspace. License labels come from package metadata; see support and licensing.

These snippets use an existing host element named element. The host owns container sizing and persistence; call instance.destroy() on teardown. Avoid duplicating preset capabilities and supply required host ports before installation.

Classic · Supported

Use the product-neutral classicEditorPreset without duplicating installed capabilities. The Word preset replaces paragraphs, headings and container lists; do not stack generic structures onto that model.

classicEditorPreset

import { createClassicEditor } from '@quirekit/classic-editor'
import '@quirekit/classic-editor/styles.css'

const instance = createClassicEditor({ element })

Block · Supported

The default createBlockEditor preset installs this capability. Configure the corresponding preset child; graphic editing uses the preset's workspace ports, while persistence and assets remain host-owned. Avoid duplicate extensions.

createBlockEditorPreset

import { createBlockEditor } from '@quirekit/block-editor'
import '@quirekit/block-editor/styles.css'

const instance = createBlockEditor({
  element,
  content: { type: 'doc', content: [{ type: 'paragraph' }] },
})
