@eigenpal/docx-editor-core
Framework-agnostic core for the docx-editor. Parses DOCX, builds the document model, runs ProseMirror, and renders Word-fidelity pages. Powers the React and Vue adapters and anything else you build on top.
Quick Start
Most users want the React or Vue adapter. Reach for core directly when building a custom adapter, running headless on the server, or driving DOCX parsing/serialization without a UI.
npm install @eigenpal/docx-editor-core
import { readFile } from 'node:fs/promises';
import { parseDocx } from '@eigenpal/docx-editor-core/docx';
const buffer = await readFile('contract.docx');
const document = await parseDocx(buffer);
console.log(document.paragraphs.length);
Each subpath tree-shakes independently. Pick the smallest entry point that gives you what you need.
Packages
| Package | Description |
|---|---|
@eigenpal/docx-editor-react |  React adapter. Toolbar, paged editor, plugins. |
@eigenpal/docx-editor-vue |  Vue 3 adapter. Toolbar, paged editor, plugins. |
@eigenpal/docx-editor-core | Framework-agnostic core: OOXML parser, serializer, layout engine, ProseMirror schema. Depend on this if you fork the React or Vue adapter. |
@eigenpal/docx-editor-i18n | Shared locale strings and types consumed by both adapters. |
@eigenpal/docx-editor-agents | Agent SDK and chat UI: framework-agnostic bridge, MCP server, AI SDK adapters, plus React UI. |
Forking the adapter? Keep your fork thin. Depend on
@eigenpal/docx-editor-coredirectly so parser, serializer, and rendering fixes land in your build automatically, without backporting each upstream change by hand.
Subpath map

|---|---|---|
| A new framework adapter | ./docx, ./prosemirror/conversion, ./prosemirror/extensions | parseDocx, toProseDoc / fromProseDoc, createStarterKit, ExtensionManager |
| Custom layout / rendering | ./layout-engine, ./layout-bridge, ./layout-painter | layoutDocument, mouseToPosition, renderPage, LayoutPainter |
| Editor commands and plugins | ./prosemirror/commands, ./prosemirror/plugins | Formatting, tables, suggestion mode, selection tracker |
Saving back to .docx | ./docx | repackDocx, attemptSelectiveSave |
| Headless agents (no UI) | ./agent | DocumentAgent, executeCommand, AgentCommand types |
| An MCP server | ./mcp | Model Context Protocol server scaffolding |
| Just unit/color/clipboard helpers | ./utils | twipsToPixels, resolveColor, font loading, clipboard, selection helpers |
| Just a type | ./types/document, ./types/content, ./types/agentApi | Document, Paragraph, Comment, AgentCommand, ... |
| Default editor stylesheet | ./prosemirror/editor.css | Import once at the top of your app |
Stability
./layout-engine, ./layout-painter, ./layout-bridge, and ./plugin-api are @experimental — used by the first-party adapters but the API may change in minor releases until a third-party adapter validates it. Pin a version range. Everything else follows SemVer.
Peer dependencies
ProseMirror packages are declared as peerDependencies so consumer bundles don't ship duplicates:
npm i prosemirror-commands prosemirror-dropcursor prosemirror-history \
prosemirror-keymap prosemirror-model prosemirror-state \
prosemirror-tables prosemirror-transform prosemirror-view
Architecture
Dual-rendering: a hidden ProseMirror instance owns editing state (selection, undo/redo, commands) while layout-painter produces the visible pages. Full breakdown: docx-editor.dev/docs/architecture.
