Setting up the Ruby dev environment on a Mac

Tested on Yosemite. Should work on El Cap. Message me if it doesn't.

Why would I want to do that?

• You are tired of using vagrant
• You want to run guard
• You want use Sublime plugins (like RSpec or Guard plugins)
• You want your code to run faster in development

CoffeeScript was written by Jeremy Ashkenas, a Ruby developer who was fed up with the quirks of JavaScript. It was an instant success in the Ruby community. Many people were tired of having to type === instead of ==, of JavaScript's crappy lexical scoping, of having to jump through hoops to set up even the most simple inheritance structure, of variables leaking into the global scope or having to worry about silly things like hoisting.

This was a time when web user interfaces were becoming more complex and backend developers had to spend more and more time writing JavaScript code. For a long time, coding in JavaScript meant you spent 100% of your time using jQuery. And what an epic mess that was!

At that time many people did not consider JavaScript to be a real programming language, because of it's oddities. So when CoffeeScript came along developers (especially Ruby developers) embraced it as a way to make coding in JavaScript suck less. I was one of those developers. I liked that CoffeeScript automatic

It's time to deploy your app! H0Lee S#!T...
-- Khurram Virani, 2014

Introduction

Localhost is great and all, but at some point you might want to deploy other app to the wild (the internets) for others to be able to use it.

When an app is live, it’s often referred to as the "production" instance/server of your app. Your your local server (on localhost) which only you can use is referred to the "development" instance.

There are many options on how and where to deploy your web app. The simplest approach is to use a Platform as a Service (PaaS). A PaaS abstracts away many of the complexities associated with setting up, configuring and deploying to a machine in the cloud. Heroku is the most popular platform of this kind.

What is TDD?

• write a test first
• see it fail
• write the implementation
• see the test pass "the red green loop"

How much should you test?
