// This file is automatically compiled by Webpack, along with any other files
// present in this directory. You're encouraged to place your actual application logic in
// a relevant structure within app/javascript and only use these pack files to reference
// that code so it'll be compiled.
//= require jquery
//= require jquery_ujs
//= require bootstrap-sprockets
//= require turbolinks
//= require_tree .

import Rails from "@rails/ujs"

import "channels"
import "bootstrap"
import "../stylesheets/application"

Rails.start()
Turbolinks.start()
ActiveStorage.start()

require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels").start()
require("jquery").start()
require("bootstrap-sprockets").start()
require("jquery_ujs").start()
require("require_tree .").start()
