Alpinejs not working in phoenix (without liveview)

evolvingdev

I’ve installed tailwindcss but oddly can’t get alpinejs to work unless I link to a cdn, which defeats my goal. Added to that, when signing out via POW, I’m getting:

no route found for GET /session

I get the same error whether I use the POW after_sign_out_path or not. This error appears related to javascript as discussed here:

Pow session path not working

Somehow I think I’ve broken js in my Phoenix install.

My assets/js/app.js:

import "../css/app.scss"

import "alpinejs"

import "phoenix_html"

My lib/myapp/pow/routes.ex:

defmodule MyWeb.Pow.Routes do
  use Pow.Phoenix.Routes
  alias MyWeb.Router.Helpers, as: Routes

  def after_sign_in_path(conn), do: Routes.notification_path(conn, :index)

  def after_sign_out_path(conn), do: Routes.page_path(conn, :index)

end

From my app.html.eex navbar:

<%= link "Sign out", to: Routes.pow_session_path(@conn, :delete), method: :delete %>

Where do I begin to work out why this is happening?

Yes, thanks, but is that necessary if I didn’t install phoenix with liveview?

Are you sure alpinejs is installed? Check your node_modules

Haha, I wondered the same earlier, thanks. But, yeah, and it’s package.json:

    "name": "alpinejs",
    "version": "3.2.1",
    "description": "The rugged, minimal JavaScript framework",
    "author": "Caleb Porzio",
    "license": "MIT",
    "main": "dist/module.cjs.js",
    "module": "dist/module.esm.js",
    "unpkg": "dist/cdn.min.js",
    "dependencies": {
        "@vue/reactivity": "^3.0.2"
    }
}

Where is alpinejs? I don’t see it in the dependencies… unless You are showing package.json from alpinejs in node_modules.

Yes, that’s the package.json file from myapp/assets/node_modules/alpinejs.

Here’s what I get from:

cd myapp/assets/

npm list --depth=0

Do you have

let liveSocket = new LiveSocket("/live", Socket, {
  params: {_csrf_token: csrfToken},
  dom: {
    onBeforeElUpdated(from, to){
      if(from.__x){ window.Alpine.clone(from.__x, to) }
    }
  }
})
