Io, Io, its off to code I go. From bit to byte I build my stack. Io, Io its off to code I go….

cd development_project_path
rails new slumgullion --database=mysql   --skip-spring --skip-listen --skip-test

And then a shift to RSpec. And then a:

cd slumgullion
# mate is my source code editor
# edit Gemfile (core package file for external components aka gems)
mate Gemfile
# Change gemfile version number to 5.2.3
# Follow directions in blog post above
bundle update
mate config/database.yml
#update database configuration file with development credentials
bundle exec rails db:create
bundle exec rails g controller Dashboard
# set the default route
mate config/routes.rb
# write a trivial def index i.e. def index end
mate app/controllers/dashboard_controller.rb
# start the server
bundle exec rails s -p3000
# open in chrome this url 
http://localhost:3000/
# get errors; remember to create a blank index template to force html rendering
touch app/views/dashboard/index.html.erb
# mate app/views/dashboard/index.html.erb
# get a blank page without any errors
# get it into version control
git add . 
git commit -m "Canonical initial commit message"
# goto git and create a private repo
# add the origin
# initial push
# create first branch paralleling first ticket id
git branch feature/1
git co feature/1

And now its time for real work. I personally believe that Rails development is always, always, always, always, always, always best done with N terminal windows where the beginning of them is as follows: Server, Database Terminal, Rails Console, General Command Line usage (add / commit / run tests / etc). Your opinion may differ but that's how I roll – keep all your tooling available at the same time. And yes it is a Zorkian experience where you can be lost in a twisty maze of terminal windows all alike.

# onto Bootstrap configuration for some appearance
mate Gemfile
# add bootsnap
# add bootstrap-saas
# stop server with command + c / ctrl c
bundle update
# port 3000 is default so omit
bundle exec rails s 
# start second terminal tab - db window
# cd development root
cd slumgullion
# start third terminal tab - console window
# cd development root
cd slumgullion
bundle exec rails c
# start fourth terminal window
cd slumgullion

Realize that after N late nights, even with examples you wrote yourself using Bootstrap, you do not know how to setup Bootstrap from scratch so sacrifice a small goat in the dark of the night whilst chanting around a firepit. When that fails to produce results, grumble and then resume with Google while chanting Save Me FreeCodeCamp. Save Me FreeCodeCamp. And like magic you channel this set of commands:

git mv app/assets/stylesheets/application.css app/assets/stylesheets/application.scss
# fix application.scss like url above directs
mate app/assets/stylesheets/application.scss
# fix application.js like url above directs
mate app/assets/javascripts/application.js
mate app/views/application.html.erb
# add a jumbotron element to see if bootstrap works
mate app/views/dashboard/index.html.erb
# restart server as per above

Success !

With thanks to Pete Jenney / Dataware for giving me the basis to make up that lyrical riff.
