Rails Engines. It’s more than just a cute name made up of two words both related to trains. Are they plug-ins? Are they microservices? When do we use them? How do we implement them? Why aren’t they used more often? Those are the questions I wish were answered for me when I first learned about Rails Engines. Inspired by Wired’s Explain In 5 Levels series, we will explore Rails Engines and address these quandaries using a variety of techniques, breaking down what engines are and how and when to use them. _____________________________________________________________ Cloud 66 - Deploy your Rails code directly from your repo to any cloud in minutes.
