A Ruby gem that is a Sinatra app generator with Rails-like simplicity. I built this to help fellow Flatiron School students with their Sinatra assessments.
rails new APP-NAME
Hazel was the closest thing I could find and this gem is based largely off of it. While it did provide a pretty good initial setup, I still had to tweak some things. The views were sitting in the root directory while I wanted them to reside in an app folder along with my models and controllers. There was also no environment.rb in the config folder as I had become accustom to having.
I also wanted to create a gem for future Learn students so they could easily get started building their projects. Although built with them in mind, this can get you off and running with any Sinatra app.
Install the gem, run
corneal new APP-NAME, run
bundle install, and you're all set! You can start up your server with
shotgunand verify everything is working. It is as simple as that.
It uses a file structure similar to what you would see with Rails.
gem install corneal
corneal -v # Show Corneal version number corneal help [COMMAND] # Describe available commands or one specific command corneal new APP-NAME # Creates a new Sinatra application corneal model NAME # Generate a model corneal controller NAME # Generate a controller corneal scaffold NAME # Generate a model with its associated views and controllers
The controller generator also have an optional views flag
--no-viewsto create controllers without views.
To generate your app:
corneal new APP-NAME
After Corneal is done generating your app, run
bundle installfrom your app's directory:
cd APP-NAME bundle install
You can then start your server with
You can generate a model and migration file:
corneal model NAME
You can also generate an entire MVC structure complete with a migration file:
corneal scaffold NAME
The resulting structure will look like this:
└─app ├── controllers │ ├──application_controller.rb │ └──new_model_controller.rb ├── models │ └──new_model.rb └── views ├──new_models │ ├──index.html.rb.erb │ ├──show.html.rb.erb │ ├──new.html.rb.erb │ └──edit.html.rb.erb ├── layout.erb └── welcome.erb
You can also add your model attributes when you generate the scaffold structure and have them added to your migration file:
corneal [model/scaffold] NAME name:string age:integer
class CreateUsers < ActiveRecord::Migration def change create_table :users do |t| t.string :name t.age :integer
t.timestamps null: false end
Visit http://localhost:9393/ to verify your app is running.
You can also verify it is working by running
rspecto see the passing test:
