Installing a Gem on Heroku from a Private GitHub Repo

Sometimes you want to use a gem on Heroku that is in a private repository on GitHub.

Using git over http you can authenticate to GitHub using basic authentication. However, we don't want to embed usernames and passwords in Gemfiles. Instead, we can use authentication tokens.

1. Get an OAuth Token from GitHub

First you will need to get an OAuth Token from GitHub using your own username and "note"

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

Intro

Problem: I learned how to run RSpec to test classes and modules in my gem. But, if I wanted to test my gem as if it were already included in a Rails app, I couldn't find much info about it online.

I usually do unit tests with RSpec, and I test the whole stack with Cucumber. So here we will just setup Cucumber to run the Rails app that you embed in your gem.

Before we begin:

• This tutorial is for people who already know how to make gems, and who have used RSpec and Cucumber before in a Rails app.
• MyGem and my_gem below refer to the name of the gem we are creating. Replace this with your own name.
