Rails in a single command
As for me, I started developing Rails apps in 2007 and I think it continues to do what it does best, focus on it's core product offering: metaprogramming. For example, here are a few commands that continue to make the Rails experience awesome.
Create an out-of-the-box app using a single line of code:
rails new [app_name] -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
Why does this single line of code kick ass? Simple, the prompt helps you build out your entire development and production environment using a single line of code.
First it asks whether you want to build a starter application.
Then it asks you which type of application. I picked
rails-devise-roles so that I can offer user registration, authentication and roles.
If you're not familiar with Devise, I suggest reading this SitePoint tutorial.
I've tried Pundit too and it's also easy to work with.
Pick your development server.
Pick your production server. I usually just pick whatever Heroku uses.
Pick your database. Again, I just pick whatever Heroku uses.
erb to be painful to work with so I'll pick HAML.
I love that I get to pick a test framework. If you're not familiar with Rspec or Capybara, I suggest this Pluralsight tutorial.
Decide if you care about Continuous testing.
I usually pick Bootstrap for a front-end development.
I'm a big fan of SendGrid for mail. Gmail is good too.
A second question about Devise. I pick #2 or #3 (Invitable).
Yes, I want an Admin interface for the database.
Yes, I will eventually add my Google Analytics tracking code.
I will likely deploy on Heroku.
Keep on Turbolinks to speed up my app.
Yes, please at a robots.txt for SEO.
Yes, please publish it to my Github repo.
WOW! All of that from a single command line. Amazing!
