• npm install fstream
• npm install tar

Do something like this on your server:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

var fstream = require('fstream'),     tar = require('tar'),     zlib = require('zlib');       res.writeHead(200, {       'Content-Type'        : 'application/octet-stream',       'Content-Disposition' : 'attachment; filename=myArchive.zip',       'Content-Encoding'    : 'gzip'     });       var folderWeWantToZip = '/foo/bar';       /* Read the source directory */     fstream.Reader({ 'path' : folderWeWantToZip, 'type' : 'Directory' })         .pipe(tar.Pack())/* Convert the directory to a .tar file */         .pipe(zlib.Gzip())/* Compress the .tar file */         .pipe(response); // Write back to the response, or wherever else...
