// You can include dependencies in two ways.
//
// 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"
//
// If you have dependencies that try to import CSS, esbuild will generate a separate `app.css` file.
// To load it, simply add a second `<link>` to your `root.html.heex` file.
