Archiver v1.3.0

Build Status Build status

a streaming interface for archive generation

Visit the API documentation for a list of all methods available.


npm install archiver --save

Quick Start

// require modules
var fs = require('fs');
var archiver = require('archiver');

// create a file to stream archive data to.
var output = fs.createWriteStream(__dirname + '/');
var archive = archiver('zip', {
    zlib: { level: 9 } // Sets the compression level.

// listen for all archive data to be written
output.on('close', function() {
  console.log(archive.pointer() + ' total bytes');
  console.log('archiver has been finalized and the output file descriptor has closed.');

// good practice to catch warnings (ie stat failures and other non-blocking errors)
archive.on('warning', function(err) {
  if (err.code === 'ENOENT') {
      // log warning
  } else {
      // throw error
      throw err;

// good practice to catch this error explicitly
archive.on('error', function(err) {
  throw err;

// pipe archive data to the file

// append a file from stream
var file1 = __dirname + '/file1.txt';
archive.append(fs.createReadStream(file1), { name: 'file1.txt' });

// append a file from string
archive.append('string cheese!', { name: 'file2.txt' });

// append a file from buffer
var buffer3 = Buffer.from('buff it!');
archive.append(buffer3, { name: 'file3.txt' });

// append a file
archive.file('file1.txt', { name: 'file4.txt' });

// append files from a sub-directory and naming it `new-subdir` within the archive'subdir/', 'new-subdir');

// append files from a sub-directory, putting its contents at the root of archive'subdir/', false);

// append files from a glob pattern

// finalize the archive (ie we are done appending files but streams have to finish yet)


Archiver ships with out of the box support for TAR and ZIP archives.

You can register additional formats with registerFormat.

Formats will be changing in the next few releases to implement a middleware approach.
