Angular2-Seed & ngx-pipes

Question

Can anyone help me to get the ngx-pipes (https://github.com/danrevah/ngx-pipes) included in the angular2-seed? I tried it like this in the project-config.ts:

additionalPackages.push({ name: 'ngx-pipes', path: 'node_modules/ngx-pipes/src/app/index.js' });

additionalPackages.push({
  name: 'ngx-pipes/src/app/pipes/*.js',
  path: 'node_modules/ngx-pipes/src/app/pipes/*/index.js'
});

but then only the main file index.js is loaded correctly, but not the subfiles.
