Hello,
sure it functions

I do this in my code :

defmodule VtmeetWeb.Component do
  use Phoenix.Component
 
  def avatar(assigns) do
    Phoenix.View.render(VtmeetWeb.LiveView, "component/avatar.html", assigns)
  end
end

And my dir is

Hope this helps,
cheers

Yes, in a nutshell this feature is not yet supported.

Currently the components I used are within liveview. So I’ve not tried what you want to accomplish.

Here is my liveview module

defmodule VtmeetWeb.LiveView do
  use VtmeetWeb, :subtemplate_view
end

and the subtemplate_view def within vtmeet_web.ex :

  def subtemplate_view do
    quote do
      use Phoenix.View,
        root: "lib/vtmeet_web",
        namespace: VtmeetWeb,
        pattern: "**/*"

      # Import convenience functions from controllers
      import Phoenix.Controller, only: [get_flash: 1, get_flash: 2, view_module: 1]

      # Include shared imports and aliases for views
      unquote(view_helpers())
    end
  end

Note the pattern which allow to find the template in subdirectories (maybe that’s what is missing in your case).

Sébastien.
