    If you are brand new to MongoDB and Rails 4, take a quick look at my very basic rails 4 mongodb tutorial before diving into this one. Gems: mongoid, omniauth, figaro Let’s get started Make sure you have Rails 4 (rails -v). We’ll make a Rails app skipping test-unit (-T), since I prefer RSpec, and omitting ActiveRecord [...]

    I’m using capybara-webkit for integration testing with rspec, which is awesome, because it is faster than other full-browser testing solutions, like Selenium, but it is slower than RackTest (default for RSpec testing).

However, his regular expressions didn’t work in the editors I use, so I whipped up some command-line options that use the flexible unix utility sed.

    It has been surprisingly hard to find a very simple tutorial to get started with Express, along with some common helpful tools, including tests! Here’s a little tutorial for Node.js v0.10 and Express 4. I’m learning Express, since I’m working on an app in SailsJS, so I will pick options that mirror choices made by… Continue reading
