How to include script/css in index on node?

Question

Angular

I am using Angular. I include files as if they came from an index that is in a separate folder

<script src="lib/angular.min.js"></script>
    <script src="lib/angular-ui-router.js"></script>
    <script src="app/app.js"></script>
    <link rel="stylesheet" href="lib/bootstrap.css">
   
    <script src="//cdnjs.cloudflare.com/ajax/libs/less.js/2.5.0/less.min.js"></script>

but everything looks like this,
to which the console answers me with an error saying nothing was found there

GET /app/lib/angular.min.js etc

Answer 1

Everything that relates to the frontend - copy / collect to the public directory
and tell the node to distribute
index.html statics and push it there
