Fizzbuzz in Elixir

Elixir is a beautiful language. Among its strength is its powerful pattern matching system which allows one to write very declarative, elegant code. FizzBuzz is a trivial problem often presented to new programmers or interviewees to determine baseline programming ability. Here is a solution Elixir:

defmodule FizzBuzz do

1. First, configure Shrine. I'll leave this exercise to the reader as it's very dependent on how you'll be storing your files (on a server, on S3, etc.)

2. Define an alternate attachment module (instead of the ActiveStorage or Paperclip one):

   module ShrineImageAttachment
     extend ActiveSupport::Concern
   
     included do
       # FIXME: Use whatever store you have defined that you want to use for product images. To avoid caching issues, I recommend using some kind of public store.

Webpack with Rails Part 1

I don't like Sprockets, but it's the easiest and best choice for lots of Ruby on Rails projects. When looking for a better way to manage my JavaScript assets and an improved developer story, my current tool of choice is webpack. While I wish Rails supported drop-in asset pipelines the way that Phoenix does, it's not hard to use webpack with Rails.

Webpack with Rails Part 3: Rake vs RSpec

In part 2 we set up a Rake task to run webpack, ensuring that most deploy systems would build our entries for us.

I missed that we needed the webpack Rake task to be run before feature tests too. Without this, we need to run the task manually before running our test suite to avoid erroneous failures due to the assets not being up to date. Running Rake tasks from anywhere in your application in relatively easy, but we

Webpack with Rails Part 2: Precompile Harder

Note: This article is more generally about how to add dependencies to a Rake task, and why you might want to do that.

If you followed my previous article on webpack and Rails, you might have built yourself a trendy little React app. Then you tried to deploy it, and that didn't work, did it?

Running React on PhantomJS

I ran into an issue getting a simple Capybara/Poltergeist feature test suite running against a site that used React.js. The following failure was bubbling up to RSpec.
