Authentication in Phoenix Framework Using Guardian - Boilerplate Code

As mentioned in the comments by David:

Phoenix now has its own auth written by Jose Valim and Aaron Renner - github.com/aaronrenner/phx_gen_auth

Therefore the method below might be unnecessary..

Here is the repo Barebones Phoenix 1.5.1 Project Using Guardian for Authentication

The protected route is /products. All other routes are free to access.

For some weird reason, the project won't compile under Windows since it requires Argon2_elixir (which requires native compilation that is not easy to set up).

To get the project working, I used WSL from within VS Code and everything works 100%.

Installing Elixir and Its Tools in WSL

wget https://packages.erlang-solutions.com/erlang-solutions_2.0_all.deb && sudo dpkg -i erlang-solutions_2.0_all.deb
sudo apt-get update
sudo apt-get install esl-erlang
sudo apt-get install elixir
sudo apt-get install build-essential
mix archive.install hex phx_new 1.5.1
sudo apt-get install -y inotify-tools

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bas
nvm install --lts

In case you need to access a PostgreSQL instance that you installed inside Windows, you can do:

sudo apt install postgresql-client-common
sudo apt-get install postgresql-client
psql -h 127.0.0.1 -p 5432 -U postgres

To start your Phoenix server:

• Install dependencies with mix deps.get
• Create and migrate your database with mix ecto.setup
• Install Node.js dependencies with cd assets && npm install
• Start Phoenix endpoint with mix phx.server

Now you can visit localhost:4000 from your browser.
