You can use archiver module, it was very helpful for me, here is an example:

var Archiver = require('archiver'),
    fs = require('fs');
app.get('download-zip-file', function(req, res){    
    var archive = Archiver('zip');
    archive.on('error', function(err) {
        res.status(500).send({error: err.message});
    });
    //on stream closed we can end the request
    res.on('close', function() {
        console.log('Archive wrote %d bytes', archive.pointer());
        return res.status(200).send('OK').end();
    });
    //set the archive name
    res.attachment('file-txt.zip');
    //this is the streaming magic
    archive.pipe(res);
    archive.append(fs.createReadStream('mydir/file.txt'), {name:'file.txt'});
    //you can add a directory using directory function
    //archive.directory(dirPath, false);
    archive.finalize();
});
