Setup

This document describes practices that are suitable for all projects. It's the same as setting up environments for Ruby or JavaScript, with some nuances: • Postgres: to make your life easier, create a user with name postgres password postgres. This is the default for most Phoenix projects. • Asdf: this is the preferred version manager for Elixir, Erlang, and Node.js. All of these steps are optional, but recommended.

Postgres

Most Elixir projects need PostgreSQL. See: PostgreSQL setup

asdf

You need Asdf version manager to install Erlang, Elixir, and Node.js. See: asdf setup

Installing Erlang, Elixir, and Node.js

Alternatives

here are other ways to acquire Postgres and Elixir: • Docker is the preferred way to get projects running. • Postgres.app is another way to install Postgres. • Kiex is an Elixir version manager. However, it doesn't manage Erlang installations (a dependency of Elixir). • You may also install Erlang and Elixir via Homebrew, though it may be • difficult to switch versions later on.
