Open-source WYSIWYG .docx editor for React and Vue with canonical OOXML, tracked changes, and real-time collaboration. Agent-ready. Live demo | Documentation

Quick Start

npm install @eigenpal/docx-editor-react

See the React quick start below.

npm install @eigenpal/docx-editor-vue

See the Vue quick start below.

npm install @eigenpal/nuxt-docx-editor

See the Nuxt quick start below.

Packages

Package	Description	Docs
`@eigenpal/docx-editor-react`	React adapter. Toolbar, paged editor, plugins.	Docs
`@eigenpal/docx-editor-vue`	Vue 3 adapter. Toolbar, paged editor, plugins.	Docs
`@eigenpal/nuxt-docx-editor`	Nuxt 3 & 4 module wrapping the Vue adapter.	Docs
`@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.	Docs
`@eigenpal/docx-editor-i18n`	Shared locale strings and types consumed by both adapters.	Docs
`@eigenpal/docx-editor-agents`	Agent SDK and chat UI: framework-agnostic bridge, MCP server, AI SDK adapters, plus UI components.	Docs

Forking the adapter? Keep your fork thin. Depend on @eigenpal/docx-editor-core directly so parser, serializer, and rendering fixes land in your build automatically, without backporting each upstream change by hand.

React

import { useState } from 'react';
import { DocxEditor } from '@eigenpal/docx-editor-react';
import '@eigenpal/docx-editor-react/styles.css';

export function App() {
  const [buffer, setBuffer] = useState<ArrayBuffer | null>(null);

  return (
    <>
      <input
        type="file"
        accept=".docx"
        onChange={async (e) => setBuffer((await e.target.files?.[0]?.arrayBuffer()) ?? null)}
      />
      {buffer && <DocxEditor documentBuffer={buffer} mode="editing" />}
    </>
  );
}

Next.js / SSR: Use dynamic import. The editor requires the DOM.

Vue

<script setup lang="ts">
import { ref } from 'vue';
import { DocxEditor } from '@eigenpal/docx-editor-vue';
import '@eigenpal/docx-editor-vue/styles.css';

const buffer = ref<ArrayBuffer | null>(null);

async function loadFile(e: Event) {
  const file = (e.target as HTMLInputElement).files?.[0];
  buffer.value = file ? await file.arrayBuffer() : null;
}
</script>

<template>
  <input type="file" accept=".docx" @change="loadFile" />
  <DocxEditor v-if="buffer" :document-buffer="buffer" mode="editing" />
</template>

Nuxt

// nuxt.config.ts
export default defineNuxtConfig({
  modules: ['@eigenpal/nuxt-docx-editor'],
});

@eigenpal/nuxt-docx-editor wraps the Vue adapter as a Nuxt 3 & 4 module: it auto-imports an SSR-safe <DocxEditor> component (no manual import, no <ClientOnly> wrapper) and the Vue composables.

Full docs: packages/nuxt.

Plugins

import { DocxEditor } from '@eigenpal/docx-editor-react';
import { PluginHost, templatePlugin } from '@eigenpal/docx-editor-react/plugin-api';

<PluginHost plugins={[templatePlugin]}>
  <DocxEditor documentBuffer={buffer} />
</PluginHost>;

See the plugin documentation for the full plugin API.

Development

bun install
bun run dev        # localhost:5173
bun run build
bun run typecheck

A live preview of main is auto-deployed at latest.docx-editor.dev — useful for trying out changes before they ship to npm.
