What "assign" function is it in LiveView pages?

On LiveView pages usually there’ll be code similar to this:

    defmodule MyAppWeb.MyPageLive.Index do
      # ..........
      defp apply_action(socket, :edit, %{"id" => id}) do
        items = Repo.get!(MyData, id)
        # ........

        |> assign(:page_title, "Edit MyData")
        |> assign(:my_data, items)

What assign() function is this? Where is it imported from precisely - from what module?

For there’re multiple modules in “deps/” that all have to do with Phoenix or LiveView and that all contain the definition ofassing(...) in them.

What version are you on? The latest has unified assign under Phoenix.Component

The function can be found here. I think it is imported when you do the use Phoenix.{LiveView, Component, LiveComponent} in your AppWeb module.
