indeed. Some times things are so obvious :melting_face:

defmodule Sample do
  require EEx

  EEx.function_from_file(
    :def, :sample, "sample.html.heex", [:assigns], engine: Phoenix.LiveView.HTMLEngine)
end

defmodule MyComponent do
  use Phoenix.Component

  def greet(assigns) do
    ~H"""
    <p>Hello, <%= assigns.name %></p>
    """
  end
end

# sample.html.heex
<MyComponent.greet name={@name} />

iex(1)> Sample.sample(%{name: "World"}) |> Phoenix.HTML.Safe.to_iodata() |> to_string()
"<p>Hello, World</p>"
