LiveView mount/3 - assign anonymous function to socket

Suppose I create a map inside mount/3 containing data from various sources:

  • session
  • get_connect_params(socket)
  • database

This map does not change during the LiveView session.

The map needs to be available to all of my LiveComponents.
When I assign the map to the LiveComponent sockets, I get a lot of copies (one for each LiveComponent), each of them change tracked, costing both memory and additional latency.

I am thinking about doing the following inside mount/3:

my_map = %{
  # fields

{:ok, assign(socket, get_my_map: fn -> my_map end)}

Does this solve my problem without creating other problems?
