Docx-Merger

Javascript Library for Merging Docx files.

This is a fork of https://github.com/scholarcy/docx-merger with updated dependencies and some fixes.

It's only been tested with NodeJS but according to the original authors it should work in the browser too.

The fork has:

• replaced webpack with esbuild as the build tool
• added type definitions

Purpose

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');
    fs.writeFileSync("output.docx", data);

If you find this library useful, you might also be interested in my other project, Webacus.

Webacus is the all-in-one toolkit designed to streamline the workflow of web developers. It solves the common problem of needing to quickly perform micro-tasks like encoding/decoding strings or formatting data by providing a unified platform with over 120 interconnected tools. Instead of searching for individual online tools, developers can access everything they need within Webacus, benefiting from a consistent interface and the ability to chain operations together for complex tasks. This local-first approach ensures speed, security, and privacy, allowing developers to focus on coding rather than managing tools.
