Create The New Auth Phoenix Project

In an empty working directory, using the mix phx.new generator, create a new Phoenix project called "auth":

mix phx.new auth

That will create a bunch of files. Most of them are "boilerplate" code for configuring the Phoenix project and a load of components. We will use some of them and delete the rest.

Run the Phoenix App

Once the dependencies are installed, run the following command in your terminal:

mix setup

Once everything is setup, run the Phoenix app with the command:

mix phx.server

Open your web browser to: http://localhost:4000

You should see something similar to the following:

Run the Tests

Just to confirm everything is working, run the tests with the following command:

mix test

You should see output similar to the following:

Compiling 4 files (.ex)
Generated auth app
.....
Finished in 0.1 seconds (0.05s async, 0.05s sync)
5 tests, 0 failures

Randomized with seed 50114

With that out of the way, let's build!
