New Rails App Checklist

How I personally start new apps

Create Project

Get the latest version of Rails

gem install rails

Create a new app

rails new <name> -d postgresql --skip-turbolinks

Don’t fret too much over the name - you can easily update it later

Version Control

Add Git

git add .
git commit -m "Hello app"

App Config

Make a few updates to config/application.rb

Disable unwanted generators

config.generators do |g|
  g.assets false
  g.helper false
  g.test_framework nil
end

Set time zone

config.time_zone = "Pacific Time (US & Canada)"

Services

Create a directory for services

mkdir app/services

And create app/services/application_service.rb with:

class ApplicationService
  include Rails.application.routes.url_helpers

  def self.perform(*args)
    new.perform(*args)
  end

  protected

  def default_url_options
    Rails.application.config.action_mailer.default_url_options
  end
end

Templates

Add Haml

gem 'haml-rails'

and run

rake haml:erb2haml

Console

Add Awesome Print

gem 'awesome_print', require: false

and have it run when the console starts in config/application.rb

console do
  require "awesome_print"
  AwesomePrint.irb!
end

Environment

Add dotenv

gem 'dotenv-rails', groups: [:development, :test]

Create an env file and exclude it from version control

touch .env
echo ".env" >> .gitignore

Lastly

Run

rails db:create
rails s

and create something awesome
