Node.js: Create Zip files

In Node.js, you can create zip files using the built-in zlib and fs modules. Additionally, you can use external libraries like adm-zip or archiver to simplify the process.

Here’s an example using archiver, a popular library for creating zip files

First, install archiver via npm

npm install archiver

Then, here’s an example script to create a zip file using archiver

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

const output = fs.createWriteStream('');
const archive = archiver('zip', {
  zlib: { level: 9 } // Compression level (optional)

output.on('close', () => {
  console.log('Zip file created successfully');

archive.on('error', (err) => {
  throw err;


// Add files or directories to the zip
archive.file('file1.txt', { name: 'file1.txt' });'images/', 'images'); // Add a directory and its contents


This script creates a zip file named and adds file1.txt and the contents of the images directory to it. Customize the paths and file names as per your requirements.

Remember to handle errors appropriately, especially when dealing with file operations. Additionally, ensure you have the necessary permissions to write files to the specified directory.
