Elixir + Phoenix Framework + Guardian + JWT + Comeonin

Preparing environment

We need to generate secret key for development environment.

mix phoenix.gen.secret
# ednkXywWll1d2svDEpbA39R5kfkc9l96j0+u7A8MgKM+pbwbeDsuYB8MP2WUW1hf

Let's generate User model and controller.

Haskell, Stack and Intellij IDEA IDE setup tutorial how to get started

Upon completion you will have a sane, productive Haskell environment adhering to best practices.

Basics

Haskell is a programming language.
Stack is tool for Haskell projects. (similar tools for other languages include Maven, Gradle, npm, RubyGems etc)
Intellij IDEA IDE is a popular IDE.

Install required libraries

sudo apt-get install libtinfo-dev libghc-zlib-dev libghc-zlib-bindings-dev

Deploying Elixir and Phoenix applications using Docker and Exrm

Goal

By the end of this quick guide, you will know how to compile a Phoenix app release using Exrm and run it inside a Docker container. I've found only a couple of articles that discuss getting an Elixir app up and running inside a Docker container, and even those only touched on some parts of the process. The idea is that this guide will give you a full end-to-end example of how to get all the pieces and parts working together so that you are able to deploy your Phoenix application inside a Docker container.

Assumptions

You already have a working Elixir environment with the Phoenix Framework installed
You have at least basic working knowledge of Docker, and have installed the Docker tools onto your local environment

Squashing Git Commits

The easy and flexible way

This method avoids merge conflicts if you have periodically pulled master into your branch. It also gives you the opportunity to squash into more than 1 commit, or to re-arrange your code into completely different commits (e.g. if you ended up working on three different features but the commits were not consecutive).

Note: You cannot use this method if you intend to open a pull request to merge your feature branch. This method requires committing directly to master.

Switch to the master branch and make sure you are up to date:

	SPC
	SPC: find file
	, switch buffer
	. browse files
	: MX
	; EX
	< switch buffer
	` eval
	u universal arg
	x pop up scratch

	# How to use it:
	#
	# Plug it at the end of your :browser pipeline in your Phoenix app router.ex
	# Make sure it is plugged before your session-based authentication and authorization Plugs.
	#
	# pipeline :browser do
	# plug :accepts, ["html"]
	# plug :fetch_session
	# plug :fetch_flash
	# plug :put_secure_browser_headers
