How to create a Elixir node without using IEx?

Question

When using Elixir’s interactive shell IEx, I can create a node by command:

iex --sname node_name

But how can I create a node by code, then run the code by:

elixir code.exs

There are some function like node(), but it seems that those function just return a node existed.

Answer 1

Use

elixir --sname node_name

Generally, you pass the node name so that everything starts up knowing its own name. However, it is apparently also possible to set the name while running with the Erlang net_kernel module, as described in the answer to How set Erlang node name...
