zipstream

Creates ZIP output streams. Depends on Node's build-in zlib module for compression available since version 0.6.

This version could use some proper testing. Give me a bump if you experience problems.

Install

    npm install zipstream

API

    createZip(options)

Creates a ZipStream object. Options are passed to Zlib.

    ZipStream.addFile(inputStream, options, callback)

Adds a file to the ZIP stream. At this moment, options must contain "name". If the "store" option is set to true, the file will be added uncompressed.

    ZipStream.finalize(callback(bytes written))

Finalizes the ZIP. When everything is done, callback is called with the total number of bytes in the ZIP archive.

Example

    var zipstream = require('zipstream'),
        fs = require('fs'),
        out = fs.createWriteStream('out.zip'),
        zip = zipstream.createZip({ level: 1 });

    zip.pipe(out);

    zip.addFile(fs.createReadStream('README.md'), { name: 'README.md' }, function() {
      zip.addFile(fs.createReadStream('example.js'), { name: 'example.js' }, function() {
        zip.finalize(function(written) { console.log(written + ' total bytes written'); });
      });
    });
