Protractor API

Note: Most commands return promises, so you only resolve their values through using jasmine expect API or using .then(function()) structure

Monolithic Components, Composable Components

Introduction

Building reusable UI components is a non trivial task, as we need to anticipate a number of things when planing for reuseability. On the one end of the spectrum we want to enable customization and on the other side we want to avoid developers doing the wrong thing, like breaking the component or displaying invalid states.

To get a better understanding of what we need to think about and consider upfront, we will build a non-trivial UI component, that displays tags. Our Tags component will take care of managing and displaying tags.

The following examples are all built with Tachyons and React, but these ideas apply to any UI component and any general styling approach.
