Then call the save function with first argument as nodebuffer, check the example below.

const DocxMerger = require('./../src/index');

const fs = require('fs');
const path = require('path');

(async () => {
    const file1 = fs.readFileSync(path.resolve(__dirname, 'template-0.docx'), 'binary');
    const file2 = fs.readFileSync(path.resolve(__dirname, 'template-1.docx'), 'binary');
    const docx = new DocxMerger();
    await docx.initialize({},[file1,file2]);
    // SAVING THE DOCX FILE
    const data = await docx.save('nodebuffer');
