Background

Sinator is Sinatra application generator. It will generate Sinatra application with minimum configuration. The reasons behind this project because I want to create many small web application based on sinatra with other third party ruby gems as foundation.

• Generate Sinatra based web application without database
• Generate Sinatra based web application with PostgreSQL database configuration and Sequel as ORM
• Rake task for assets precompile and assets clean

gem install sinator

with Bundler, put this code in your Gemfile:

gem 'sinator'
