    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
    const fs = require('fs');
    const archiver = require('archiver');
    // create a file to stream archive data to.
    const output = fs.createWriteStream(__dirname + '/');
    const archive = archiver('zip', {
      zlib: { level: 9 } // Sets the compression level.
    // listen for all archive data to be written
    // 'close' event is fired only when a file descriptor is involved
    output.on('close', function() {
      console.log(archive.pointer() + ' total bytes');
      console.log('archiver has been finalized and the output file descriptor has closed.');
    // This event is fired when the data source is drained no matter what was the data source.
    // It is not part of this library but rather from the NodeJS Stream API.
    // @see:
    output.on('end', function() {
      console.log('Data has been drained');
    // 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
    const 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
    const 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
    archive.glob('file*.txt', {cwd:__dirname});
    // finalize the archive (ie we are done appending files but streams have to finish yet)
    // 'close', 'end' or 'finish' may be fired right after calling this method so register to them beforehand


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

    You can register additional formats with registerFormat.

    You can check if format already exists before to register a new one with isRegisteredFormat.

    Formats will be changing in the future to implement a middleware approach.
