Mastering the Art of Programming in Elixir

GenServer Callbacks

Explore the six key GenServer callback functions used in Elixir's OTP framework to manage server processes. Understand how to implement and override functions like init, handle_call, handle_cast, and others to build and control server behavior effectively.

We'll cover the following...

GenServer

init(start_arguments)
handle_call(request, from, state)
handle_cast(request, state)
handle_info(info, state)
terminate(reason, state)
code_change(from_version, state, extra)
format_status(reason, [pdict, state])
{ :noreply, new_state [ , :hibernate | timeout ] }
{ :stop, reason, new_state }
{ :reply, response, new_state [ , :hibernate | timeout ] }
{ :stop, reason, reply, new_state }
