Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.

Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

# Rack::Test doesn't support hitting external webservers.  However, when a user enters their credit card info,
# it is submitted directly to braintree, so we need to intregration test with hitting an external server.

# This hack enabled this, by swapping out the Rack::Test's rack app with a Rack::Client instance.
# Rack::Client acts just like a rack app, but under the covers it delegates to Net::HTTP.
