nix-shell for Phoenix

WIP

What is it?

A nix-shell template to set a Phoenix development environment up with direnv integration (if installed).

Built gathering inspiration from several sources, it makes available:

• unstable.elixir
• unstable.elixir_ls (LSP)
• nodejs-12_x for WebPack swing
• rebar3 via setup script: erlang build tool that makes it easy to compile and test erlang applications and releases
  • currently installed from the setup script: check TODO
• Phoenix version 1.5.9 installed via setup script
• unstable.postgresql_14 setup
  • TODO: check/complete PostgreSQL section

Working with a local PostgreSQL instance

initdb --no-locale --encoding=UTF-8
pg_ctl -l "$PGDATA/server.log" start
createuser postgres --createdb
mix ecto.setup

Because we are too lazy to run all these commands by hand each time Iwe need to setup a project and because automation is good: ejpcmac's Setup script for Phoenix projects using Nix and PostgreSQL

My fork of ejpcmac's script (never knows).

To stop our local PostgreSQL instance:

pg_ctl stop
