Elixir

Required

elixir erlang

Optional

inotify-tools sqlite postgresql erlang-core

1. Install the system package for Elixir.

2. Install the erlang package, for the most seamless experience. You can instead choose to install the Erlang Core package only and install something like erlang-asn1 when needed.

Phoenix (LiveView)

Note

Regarding LiveView, as stated on the project’s GitHub page:

LiveView ships by default in new Phoenix applications.

This means you can simply setup Phoenix for LiveView capabilities.

1. Install inotify-tools for Live Reloading to work, as stated in the Phoenix docs.

2. If you plan on using PostgreSQL, install the postgresql package and consult the Arch Wiki page for anything specific.

   If you instead want to use SQLite, install the sqlite package and, again, consult the Arch Wiki page for anything specific.

New Project

If you’re writing a new application

1. Make sure the Phoenix application generator is installed:

   mix archive.install hex phx_new

2. Create a new application

   mix phx.new <project-name>

   or if you prefer SQLite to PostgreSQL, use

   mix phx.new <project-name> --database sqlite3

3. Switch to the new directory

   cd <project-name>

4. Init your version control

   git

   git init

   jujutsu

   jj git init

5. Setup the database

   mix ecto.create

6. Start the Phoenix server

   mix phx.server
