Background

In our app, we have a number of different has-zero-or-one relationships where the foreign object may or may not exist. For example, a Customer may or may not have a CreditCard on file, but it won't have more than one.

We started with something like

// app/models/customer.js
export default DS.Model.extend({

const STATUSES = {
  initial: {},
  fetching: { showLoadingIndicator: true },
  fetched: { showResults: true },
  error: { showError: true },
}

function Foo() {
  const [status, setStatus] = useState(STATUSES.initial)
  const [results, setResults] = useState(null)

Tired of building custom navigation code for each site?

Have you seen Ryan Heath's Navigation Helper? It's very usable, but it only does one nav-bar. I often have sites where there are many, e.g.

+-----------------------------------------------------------+
| MyApp                           | Home | Sign Out | FAQ | | # "site" nav bar
|===========================================================|
| | *Projects* | Friends |                                  | # "area" nav bar
|===========================================================|

| | Project Overview | Budget | History | | # "tabs" nav bar

I don't have a Grand Vision for (S)CSS, but I do have some ideas.

Cohesion & Coupling

In JavaScript (and any other "programming language"), we value cohesion and eschew coupling. To value cohesion is to say that all of the foo-related things are in the Foo component or the app/pods/foo pod or the lib/foo addon. Like things are together. To eschew coupling is to say that two unrelated things should not need to know about one another. Unlike things don't rely on one another. Further reading on Cohesion & Coupling:

• http://courses.cs.washington.edu/courses/cse403/96sp/coupling-cohesion.html (my favorite reference on the topic)
• http://enterprisecraftsmanship.com/2015/09/02/cohesion-coupling-difference/ (good visuals)
• http://c2.com/cgi/wiki?CouplingAndCohesion
• https://en.wikipedia.org/wiki/Connascence_(computer_programming) (connascense is closely related to cohesion)

The following code will let an ember addon provide an addon-test-support/ folder whose contents get merged into app/mirage/. It excludes addon-test-support/ from the build if mirage is disabled.

See Better Addon Support on the Ember CLI Mirage feature-request board.

Off the top of my head, a UX team needs to collectively have the following talents. No one person will know all of these, nor would I expect someone who is learning something in the Advanced category to have fully mastered everything above. Paths vary.

Prerequisites

• Writing and rhetoric, including constructing a thesis, providing supporting evidence, and tailoring your delivery to your audience
