Background

Melodiest is Sinatra application boilerplate. It provides generator and contains minimum configuration to develop application with Sinatra. The reason why I create Melodiest is because I want to create many small web application based on sinatra with other third party ruby gems as foundation. Originally, I wanted to name this project as Harmony or Melody, but because it was already taken I decided to name this project as Melodiest.

Installation

gem install melodiest

with Bundler, put this code in your Gemfile:

gem 'melodiest'

How to Use

generate app in current directory without database

melodiest -n my_app

generate app in target directory without database

melodiest -n my_app -t target/dir

generate app in current directory with database. -d option will generate app with Sequel orm and PostgreSQL adapter.

melodiest -n my_app -d

This example assume that PostgreSQL is already running and desired database is already exist. For complete example see github.com/kuntoaji/todo_melodiest

        String :name, :null=>false
