In this post, Brent Schooley from Twilio explains how to create reusable web components in Ember.js 2.0 using the Custom Elements spec. He uses Firebase and Ember Data to store customer data and creates a component to display trial customers and subscribers with different columns for each group. The component is designed to be reused throughout the application, reducing code duplication and improving maintainability. Schooley also discusses the benefits of using components in Ember applications and provides tips on how to use them effectively.
