Subject: Re: re couchapp with node

couchapp.loadAttachments(ddoc, path.join(__dirname, 'attachments'));
adds all files under the directory "attachments" as attachments to the
design doc.

ddoc.views.lib =3D couchapp.loadFiles('./lib');
adds any js files in the "./lib" directory as commonjs modules to your
views, which you can then use in your views. Here's a snippet from one
of mine:

ddoc.views.alpha =3D {
  map : function(doc) {
    if(doc.type =3D=3D 'event') {
      var skey   =3D require('views/lib/util').sanitizedKeyData(doc);
      var cvalue =3D require('views/lib/util').commonEmitValue(doc);
      emit(skey.name, cvalue);
    }
  },
  reduce : "_count"=09
}

./lib/utils.js looks like this:

exports.commonEmitValue =3D function(doc) {
  return({...});
}

exports.sanitizedKeyData =3D function(doc) {
  // set vars and manipulate stuff
  return({...});
}

You can also define ddoc filters in a similar fashion:

ddoc.filters =3D couchapp.loadFiles('./filters');

Hope this somewhat incoherent reply helps point you in the right direction.
