The Hunt for the right HTTP library

Use case: Travis CLI. One command invokes one or more sequential HTTP requests.

Note that startup time and the first request are very significant for a command line tool like this.

Clone the repo if you want to follow along.

Note: numbers might be due to how libraries are used (via faraday)

Your class can be no longer than 100 lines of code.
Your methods can be no longer than five lines of code.
You can pass no more than four parameters and you can’t just make it one big hash.
When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.
