How do I use Bootstrap 4 with Parcel on the client side of my app?

Question

Per Bower's site they recommend using Parcel for the frontend. In the past I've done this with Bower as:

npm install -g bower

In my app.js I tell Express the location of the client side:

app.use(express.static(path.join(__dirname, 'public')))

In the .bowerrc @ root level it includes:

{
  "directory":"public/bower_components"
}

and in the terminal I run bower i bootstrap and bower i jquery.

Results are:

/application
  /models
  /node_modules
  /public
    /bootstrap
    /jquery
  /views
    index.pug
  .bowerrc
  app.js
  package.json

in pug I'm calling Bootstrap as:

doctype html
html
  head
    title #{title}
    link(rel='stylesheet' href='/bower_components/bootstrap/dist/css/bootstrap.min.css')
  body
    block content
    br
    hr

How can this be done in Parcel instead of Bower? All I was able to find from my research was: "How do I use jQuery and jQuery-ui with Parcel (bundler)?" Cannot find any results in the documentation of Parcel.
