Render functional component directly in controller without .html.heex template?

I think that may be just weird wording referring to how you can do this:

def MyAppWeb.FooController do
  use MyAppWeb, :controller

  def index(conn, _params) do
    render(conn, :index)
  end
end

def MyAppWeb.FooHTML do
  use MyAppWeb, :html

  def index(assigns) do
    ~H"""
    My template
    """
  end
end

def index(assigns) is a component which is rendered from the controller by referencing its name as opposed to “rendering a template from the controller.” AFAIK, you can’t render heex inside a controller action which is what you’re asking. If you have some better wording you could always open a PR to improve!

It’s possible I’m wrong and you can do what you’re asking but I’ve searched through the docs and can’t find anything. render doesn’t take HEEx at all.

There is no requirement to have a view layer:

@sodapopcan thanks, this is what I was looking for! The examples I came across render a .html.heex “template” rather than a component directly. But this answers "how to skip the .html.heex templates. I’ll send a PR to docs to add this example as well

@LostKobrakai that’s interesting! letting you skip the view layer (i,e, MyAppWeb.FooHTML) completely
