Always place js / css files in a public folder. In your case, try to do this. Create an entire copy of the data folder in the shared folder.
For stylesheet.
<link rel="stylesheet" type="text/css" href="{{url('assets/css/bootstrap.min.css')}}"/>
And for the JS file ..
<script src="{{url('assets/js/components/bootstrap.js')}}"></script>
