Is a simple calculator that performs the operations ['+', '-', '*', '/', '**', 'sqrt'] that gets filled on the frontend ember app and performed on the backend rails app. I used ember-cli-rails to embed the ember app inside the rails app.

Setup:

• With an installation of ruby, version 2.4.2
• run gem install bundler
• run bundle

To run the tests:

• cd frontend && ember test --server for the frontend ember app
• rspec for the rails app

• Add the operations from the backend
• Polish frontend
• Properly handle unary operations
• Refactor frontend to use components
• Add more tests for frontend
