5// You can include dependencies in two ways.
6//
7// The simplest option is to put them in assets/vendor and
8// import them using relative paths:
9//
10// import "../vendor/some-package.js"
11//
12// Alternatively, you can `npm install some-package --prefix assets` and import
13// them using a path starting with the package name:
14//
15// import "some-package"
16//
17// If you have dependencies that try to import CSS, esbuild will generate a separate `app.css` file.
18// To load it, simply add a second `<link>` to your `root.html.heex` file.
