# Add this to your config/webpack/environment.js file.

# Next add this to your application.js file.
require("bootstrap")
import "../../assets/stylesheets/application";
document.addEventListener("turbolinks:load", function() {
    $(function () {
        $('[data-toggle="tooltip"]').tooltip()
        $('[data-toggle="popover"]').popover()
    })
})

# Rename application.css to application.scss.
# Then simply import bootstrap. For me this path worked.
@import "bootstrap/scss/bootstrap";

# And if that doesn't work try.
@import "~bootstrap/scss/bootstrap";
