@docen/docx

DOCX editor and converter powered by @office-open/docx with Tiptap editing layer, supporting bidirectional conversion between DOCX and Markdown (styled HTML is accepted as paste input).

Need a ready-made visual editor? @docen/editor wraps this engine in a Fluent UI host with the turnkey <docen-document> web component.

Features

• 📝 Viewless Tiptap engine — the DOCX editing model with DOCX-aware extensions; rendering belongs to the host (e.g. @docen/editor's canvas stage)
• 🔄 DOCX Round-trip — Near-lossless DOCX ↔ Editor conversion via @office-open/docx
• 📄 Markdown Support — Tiptap JSON ↔ Markdown conversion
• 🎨 DOCX Properties — Custom Tiptap extensions carry shading, borders, indent, spacing, floating, crop
• 🔗 Template Patching — Replace {{placeholders}} in DOCX templates with Tiptap-JSON content

Installation

# Install with pnpm
$ pnpm add @docen/docx

# Install with npm
$ npm install @docen/docx

Quick Start

import { docxExtensions, parseDOCX, generateDOCX } from "@docen/docx";
import { Editor } from "@docen/docx/core";

// Viewless: the editor is the editing model — rendering belongs to the host.
const editor = new Editor({
  element: null,
  extensions: docxExtensions,
  content: await parseDOCX(buffer),
});

// Save back to DOCX
const output = await generateDOCX(editor.getJSON());

API

Standalone Functions (Core)

These work without an editor instance — for headless/server/batch use.

import {
  parseDOCX,
  generateDOCX,
  generateDOCXSync,
  generateDOCXStream,
  parseMarkdown,
  generateMarkdown,
} from "@docen/docx";

// DOCX pipeline: DOCX binary ↔ Tiptap JSON
const json = parseDOCX(buffer); // → JSONContent
const buffer = await generateDOCX(json); // → Buffer (pre-fetches http images by default)
const blob = await generateDOCX(json, { packer: { type: "blob" } }); // → Blob
const sync = generateDOCXSync(json); // → Buffer (skips prepare)
const stream = await generateDOCXStream(json); // → ReadableStream<Uint8Array>

// Markdown pipeline: Markdown string ↔ Tiptap JSON
const json = parseMarkdown("# Hello"); // → JSONContent
const md = generateMarkdown(json); // → string

Editor

import { createDocxEditor, docxExtensions } from "@docen/docx";

const editor = createDocxEditor({
  element: document.querySelector("#editor"),
  extensions: docxExtensions,
  spellcheck: true,
  editable: true,
});

Need a ready-made editor UI? @docen/editor's <docen-document> bundles this engine with open/save, canvas rendering, and the Fluent host.

Template Patching

Replace {{placeholders}} in a DOCX template with Tiptap-JSON content. Each patch's content is prepared (default: fetch http images) then compiled to DOCX.

import { patchDOCX, parseMarkdown } from "@docen/docx";

const result = await patchDOCX({
  template: templateBuffer,
  patches: {
    title: { content: parseMarkdown("# Report") },
  },
  outputType: "nodebuffer",
});

Advanced: Model Bridge

generateDOCX runs prepareDocument → compileDocument → generateDocument internally. You rarely need these directly — reach for them only when working with the intermediate DocumentOptions (the OOXML persistence model):

import { resolveDocument, compileDocument, prepareDocument } from "@docen/docx";

const json = resolveDocument(docOpts); // DocumentOptions → JSONContent
const docOpts = compileDocument(json); // JSONContent → DocumentOptions
await prepareDocument(json); // in place: http image URLs → data URLs

Architecture

Standalone Functions (core)
  parseDOCX / generateDOCX / generateDOCXSync / generateDOCXStream / patchDOCX
  parseMarkdown / generateMarkdown
  resolveDocument / compileDocument / prepareDocument  (model bridge, advanced)
        ↕ used by
createDocxEditor / docxExtensions — the viewless Tiptap editing model
        ↕ rendered by
@docen/editor's canvas stage (LeaferJS pages, caret/selection mapping)

• Runtime model: Tiptap JSON with DOCX-rich attributes via custom extensions
• Persistence model: DocumentOptions (complete OOXML expressiveness)
• Standalone functions are core — the editor bindings are thin wrappers
