Quick Start

import { generateDocument } from "@office-open/docx";
import { writeFileSync } from "node:fs";

const buffer = await generateDocument({
  sections: [
    {
      children: [
        {
          paragraph: {
            children: ["Hello World", { text: " - Bold text", bold: true }],
          },
        },
      ],
    },
  ],
});

writeFileSync("My Document.docx", buffer);

Benchmark

Performance vs original docx (9.6.1) package (higher ops/s is better, Windows 11 / Node 24).

Default = XML DEFLATE level 1 (SuperFast, matching MS Office) + media STORE. All STORE = no compression ({ compression: { xml: 0 } }). docx (async only) always uses DEFLATE for ALL entries including images (via JSZip, hardcoded, no STORE option).

// Default (matches MS Office)
await generateDocument(options);
// All STORE (no compression)
await generateDocument(options, { compression: { xml: 0 } });
