Prelude

I. Preface and Motivation

This guide was written because I don't particularly enjoy deploying Phoenix (or Elixir for that matter) applications. It's not easy. Primarily, I don't have a lot of money to spend on a nice, fancy VPS so compiling my Phoenix apps on my VPS often isn't an option. For that, we have Distillery releases. However, that requires me to either have a separate server for staging to use as a build server, or to keep a particular version of Erlang installed on my VPS, neither of which sound like great options to me and they all have the possibilities of version mismatches with ERTS. In addition to all this, theres a whole lot of configuration which needs to be done to setup a Phoenix app for deployment, and it's hard to remember.

For that reason, I wanted to use Docker so that all of my deployments would be automated and reproducable. In addition, Docker would allow me to have reproducable builds for my releases. I could build my releases on any machine that I wanted in a contai

Migrations & Seeding

What are migrations??

Migrations are a way to make database changes or updates, like creating or dropping tables, as well as updating a table with new columns with constraints via generated scripts. We can build these scripts via the command line using knex command line tool.

To learn more about migrations, check out this article on the different types of database migrations!

Creating/Dropping Tables

Tested with Phoenix 1.3

1) Installing sass, font-awesome and bootstrap package's using Brunch

First, install the Sass, Font Awesome, bootstrap(and deps) package:

cd assets

npm install --save-dev sass-brunch
npm install --save font-awesome

It's now here, in The Programmer's Compendium. The content is the same as before, but being part of the compendium means that it's actively maintained.

JXA Resources

Revised: 2019-11-28 16:16 GMT-6

This is a list of the key resources I have found useful. If you know of others, please post in a comment below, and I will add to this list.

I have tried to order this list in the order that, to me, is best for learning JXA from scratch. We all learn a bit diferently, so adjust to suit your style/needs. Please post if you have suggestions on learning JXA.

	## Pre-requisite: You have to know your last commit message from your deleted branch.
	git reflog
	# Search for message in the list
	# a901eda HEAD@{18}: commit: <last commit message>

	# Now you have two options, either checkout revision or HEAD
	git checkout a901eda
	# Or
	git checkout HEAD@{18}
