Create a New Rails App

As I started a new rails project today, I thought about how to create the initial Rails app and knew that last time I used a template. But I was not sure which one, therefore I document it this time for myself and for people who don’t know this solution.

Setting up a new Rails project with all required GEMs takes quite some time. But not when you use the fantastic Rails Composer. This template asks all the important questions for a perfect initial Rails app. You simply have to execute following command:

rails new myapp -m

Then you get asked which gems you want to use: database, testing framework, integration testing, template language and so on. It is all covered. And finally you have your project ready to start coding in no time.
