Archiver v1.2.0

a streaming interface for archive generation

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

Install

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 + '/example.zip');
var archive = archiver('zip', {
    store: true // Sets the compression method to STORE.
});

// 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 this error explicitly
archive.on('error', function(err) {
  throw err;
});

// pipe archive data to the file
archive.pipe(output);

// 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 = new Buffer('buff it!');
archive.append(buffer3, { name: 'file3.txt' });

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

// append files from a directory
archive.directory('subdir/');

// append files from a glob pattern
archive.glob('subdir/*.txt');

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

Formats

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.
