Package management on Erlang and Elixir

Question

I searched for package management on Erlang and Elixir and got some pointers to rebar rebar3 mix hex and relx etc. Can you help clarify the relationships among them? Where to use what? Is package just synonym to Erlang's application made up of modules?

Answer 1

A package is synonym to Erlang or Elixir application/ library made up of one or more modules

Hex is currently the preferred package manager for the Erlang ecosystem (ERLANG, LFE, JOXA & ELIXIR)

rebar3 + hex.pm: For Erlang package management rebar3 uses hex.pm, a package manager for Erlang and Elixir packages. more Documentation

mix + hex.pm: For Elixir package management mix uses hex.pm, a package manager for Erlang and Elixir packages. more Documentation

To add a little extra info to @byaruhaf's answer, rebar3 is a new and improved rebar, relx is a release management tool, not package management, so you can safely ignore that in this context. – Micrometer

Answer 2

In addition to everything @byaruhaf mentioned, erlang.mk provides simple package index functionality that allows for basic management of Erlang dependencies. It's very primitive compared with hex but it might be all you need. If your already have a Makefile for your project erlang.mk is probably the quickest way to add basic package management functionality to your project.
