node.js - sending multiple files down the pipe -

we're using express 4 , right have this:

var express = require('express'),     router = express.router();  router.get('/local_modules/*', function (req, res, next) {    var modulename = req.url.match(/local_modules\/(.*?)\//).pop(1)    res.sendfile(filepath + '.js'); } 

and wanna more like:

router.get('/local_modules/*', function (req, res, next) {    var moduledir = req.url.match(/local_modules\/(.*?)\//).pop(1)     fs.readdir(moduledir, function(err, files) {       files.foreach(function(f) {          res.sendfile(path.join(moduledir, f));      })    }  } 

but doesn't work. how can serve multiple files express? note: not files in directory (like in example) - can done app.use; express.static , specific set of files (e.g. may need list of files bower.json)

there no way send multiple files in single response, unless use own special formatting (standard multipart or otherwise) , parse on client side (e.g. via xhr).

probably easiest workaround archive (zip, 7zip, tarball, etc.) files , serve archive instead. assumes want user download , not use files in browser (unless have zip, etc. parser in browser , use xhr).
