pub fn hello() -> Result<(), DocxError> {
    let path = std::path::Path::new("./hello.docx");
    let file = std::fs::File::create(path).unwrap();
    Docx::new()
        .add_paragraph(Paragraph::new().add_run(Run::new().add_text("Hello")))
        .build()
        .pack(file)?;
    Ok(())
}

Browser

import { saveAs } from "file-saver";

// // Note that a dynamic `import` statement here is required due to webpack/webpack#6615,
import("docx-wasm").then((w) => {
  const { buffer } = new w.Docx()
    .addParagraph(
      new w.Paragraph().addRun(new w.Run().addText("Hello world!!"))
    )
    .build();
  saveAs(new Blob([buffer]), "hello.docx");
});

Node.js

const w = require("docx-wasm");
const { writeFileSync } = require("fs");

const { buffer } = new w.Docx()
  .addParagraph(new w.Paragraph().addRun(new w.Run().addText("Hello world!!")))
  .build();

writeFileSync("hello.docx", Buffer.from(buffer));
