Upload images with React and the carrierwave Ruby gem for Rails 5

I recently attended a 4.5 month, intensive coding bootcamp in Boston, MA called Launch Academy. I spent a lot of time in academic science doing imaging research, so I naturally had an interest in learning how to manipulate images in this new web browser environment. For my capstone project, I created a very simple image editing Rails app where I realized I needed to be able to save/upload images to my database.

Since, through earnest effort, I wanted my app to use React for a single-page experience, and I quickly discovered that my desire to use a React/fetch/carrierwave/fog/Rails strategy was initially difficult to learn. I had to pull information from many sources (StackOverflow, Medium, official docs, other blog posts, course instructors, etc) to develop a method that uses this specific POSTing cycle.

This blog post represents my findings to integrate all these technologies in a modern, seamless

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.

  Include in your rspec config like so:

  RSpec.configure do |spec|
    spec.include RSpec::RedisHelper, redis: true
  end

  This helper will clean redis around each example.

Disclaimer: The following examples try to give an overview of the process followed in different scenarios. Some commands were actually written from memory. Some tools might exist simplifying all this. Furthermore, I'm no expert so if anyone ever reads this and knows any improvement, please let me know.

Case 1: Direct access to Pairing Station

Given that the Guest User can access the Pairing Station directly, either because the station is publicly available or because NAT port forwarding can be used, there's only one thing we need to do, give ssh access to the Guest User by adding his ssh public key to our Local User (pair) .ssh/authorized_keys file.

The local user would open up a tmux session with

tmux new-session -s pairing
