Groxio Phoenix Jan 2024

Groxio Custom Elixir and Phoenix Course

1 Install these tools, plus Elixir, plus Phoenix.

The tools you will need to install:

• zoom with a working camera (We'll keep cameras on as much as possible)
• git (https://git-scm.com/downloads).
• an editor that you are comfortable with.
• a working PostgreSQL install

For the development dependencies, you'll need:

• Elixir 1.16, with OTP 26. Make sure it's working:

run the command:

[course] ➔ iex
Erlang/OTP 26 [erts-14.0.2] [source] [64-bit] [smp:10:10] [ds:10:10:10] [async-threads:1] [jit]

Interactive Elixir (1.16) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> 

• Phoenix 1.7.x. This version of Phoenix is significantly different than previous ones.

Is Phoenix working? Make sure you can run this command:

mix phx.new demo
(say yes to fetch dependencies and assets)

and make sure you can then create the database:

cd demo
mix ecto.create

Don't save this for the last minute! There are a few dependencies that will give you trouble if you've never done this before and decide to wait.
