So just to be clear, this now all depends on someone running bower before building, for that reason I think we should add bower to the package.json under `devDependencies`.

Then in package.json we can add something like.
```json
"scripts": {
  "bower": "./node_modules/bower/bin/bower install"
}
```

So an admin then only has to do something like

`npm install`
`npm run-script bower`
