// The simplest option is to put them in assets/vendor and
// import them using relative paths:
//
//     import "../vendor/some-package.js"
//
// Alternatively, you can `npm install some-package --prefix assets` and import
// them using a path starting with the package name:
//
//     import "some-package"
//

// Include phoenix_html to handle method=PUT/DELETE in forms and buttons.
import "phoenix_html";
// Establish Phoenix Socket and LiveView configuration.
