So far in this series, we have looked at the benefits of using a Boilerplate to streamline your workflow, and a two articles on how to setup a React Boilerplate with parcel instead of Webpack, and a traditional means to compile and bundle a traditional HTML/SCSS project using Parcel. So, what about Rails?

Config File

If you’ve used Unix/Linux for any length of time, you’re familiar with dotfiles. They’re those files beginning with a . and usually ending with rc: .bashrc, .vimrc, and .zshrc being familiar examples. Modifying these files allows you to configure the behavior of the associated program, and can be a never ending quest for some to get the “perfect” setup.

You can streamline new Rails project creation with the use of a .railsrc file. There are a few rules:

The file must be named .railsrc (don't forget the preceeding .
The file must be placed in the users path. So, it has to be in your $HOME directory.

Follow these simple rules, and the rails new command will inject commands to the command line silently. For instance, I never use the default Rails database SQlite, I always add the commandline switch to use Postgres. Do I want to type this every time? NO!!!!!

So my simple .railsrc file:

--database=postgresql

I can start a new project: rails new cool_app and silently the postgresql flag is added to the install process.

What are your defaults? What do you change or use each time? A more involved setup may look like this:

--database=postgresql
--webpack
--skip-action-cable
--skip-spring
--skip-turbolinks

There is more we can do.

Template Files

The last line of the .railsrc file is reserved for template files that will run during install. So, let's look at my simple railsrc file again:

--database=postgresql
--template=/path/to/file/rails-template.rb

I have stored my simple template file locally, and you can name as you like. Here is my simeple script:

#add guard-minitest and spring to dev

gem_group :development do 
  gem 'pry-rails'
  gem 'awesome_print'
end

gem_group :test do
  gem 'guard'
  gem 'guard-minitest'
  gem 'minitest'
  gem 'minitest-reporters'
  gem 'rails-controller-testing'
end

run "bundle install"

generate :controller, "static_pages home"
route "root 'static_pages#home'"

run "cp ~/development/my-docs/starter/renovate.json ."
run "cp ~/development/my-docs/starter/LICENSE ."
run "cp ~/development/my-docs/Guardfile ."

#create postgres DB for postgress.app
run "psql -c 'CREATE DATABASE #{app_path}_development;'"
run "psql -c 'CREATE DATABASE #{app_path}_test;'"

In this template I am setting up my beginning project preferences:

Set up a better console printing with awesome_print
Setup my preferred testing environment
Bundle install
Setup a static controller for the Home page
Copy a few files
Create the Postgres databases.

So, all I have to do, is change to the new project directory and start the Rails server. The DB is setup enough to get started. This works for me but I want to do more.

More Resources

Matt Brictson has put together a more full featured Rails template that is preloaded with the best practices for TDD, security, deployment, and developer productivity.

Jumpstart

Building on the work of Matt's open source template Chris Oliver has put together a template called Jumpstart. This template creates a Boilerplate app that includes user accounts, admin interface, and Bootstrap styling.

Jumpstart Pro

Chris also has a commercial product called JUmpstart Pro that bootstraps a full featured e-commerce application setup.

Post install template

What about automating post-install tasks? Wel,, I highly recommend going to the free service RailsBytes and try some templates out.

For instance, do you want to install Rubocop:

rails app:template LOCATION='https://railsbytes.com/script/V33sBe'

Thats it. Check it out.

Rails Minimal

Finally, there is a new feature coming to the rails new command to create a minimal application. The original pull request has been merged, but there appears to be still some documentation pull request in the works. When it is finished and deployed the command rails new cool_app --minimal will look like the following:

skip_action_cable
skip_action_mailbox
skip_action_mailer
skip_action_text
skip_active_job
skip_active_storage
skip_bootsnap
skip_jbuilder
skip_spring
skip_system_tests
skip_turbolinks
skip_webpack
Sprockets should have JavaScript folders by default
rails new --minimal webpack=react still works

When fully deployed, this will be a nice feature to have for streamlining the workflow.
