This tutorial is the fourth part of our series on test-driving an Ember.js application. Here’s a quick recap of our last tutorial. We first started building out our Ember application using a route plus a template. We then transitioned our work to a component, which is where we’ll start from in this tutorial. We weren’t […]

In the last tutorial in this series, we created an API using Rails 5 (which just went to Beta 1). In that tutorial, we mostly focused on the server, but we also considered what we were going to do with the Ember application we built in the first tutorial in the series. We recommend that […]
