How to tell if the page is an inertia page

[Morzaram]

Hey there, since I'm migrating from LiveView/ have a few pages that don't need inertia I wanted to share how I determine if I should load the inertia entrypoint. It feels dirty since I'm accessing keys in private but none the less I can't figure out a better way. Thought I'd share for people that are looking for how to do this or for a better way

In your .heex simply call.
@conn.private[:inertia_page]

Like

<%= if @conn.private[:inertia_page] do %>
  <%= vite_js_tag(assigns, "inertia.tsx") %> // Custom code
<% end %>

Thanks for sharing this @Morzaram! It would be good for us to add an official helper function to determine if the response is an Inertia-powered response.

I added this helper to the latest release (2.2.0): https://hexdocs.pm/inertia/Inertia.Controller.html#inertia_response?/1
