Let's Make A Dropdown

Here, we intend a component that can be used for something like a user menu in a nav. Maybe you've heard it called "popover" or something like that.

It is not meant to be a select element, or used in a <form>.

Goals:

make a component that other developers can consume as an addon
it should be accessible

ESLint rules

The ESM standard is considered stable in NodeJS and well supported by a lot of modern JavaScript tools.

ESLint does a good job validating and fixing ESM code (as long as you don't use top-level await, coming in ESLint v8). Make sure to enable the latest ECMA features in the ESLint config.

TL;DR

In Ember, always use {{...}}, not {{{...}}}. Use Ember.String.htmlSafe as necessary in JavaScript (usually in a component) to mark markup as HTML-safe. Never pass user-entered content directly to Ember.String.htmlSafe.

Ember has great XSS protection built in. The HTMLBars templating library will automatically run any interpolations through htmlEscape for you. So

Season's Greetings, NSHipsters!

As the year winds down, and we take a moment to reflect on our experiences over the past months, one thing is clear: 2014 has been an incredible year professionally for Apple developers. So much has happened in such a short timespan, and yet it's hard to remember our relationship to Objective-C before Swift, or what APIs could have captivated our imagination as much as iOS 8 or WatchKit.

It's an NSHipster tradition to ask you, dear readers, to send in your favorite tips and tricks from the past year for publication over the New Year's holiday. This year, with the deluge of new developments—both from Cupertino and the community at large—there should be no shortage of interesting tidbits to share.

Submit your favorite piece of Swift or Objective-C trivia, framework arcana, hidden Xcode feature, or anything else you think is cool, and you could have it featured in the year-end blowout article. Just comment on this gist below!

Components are taking center stage in Ember 2.0. Here are some things you can do today to make the transition as smooth as possible:

Use Ember CLI
In general, replace views + controllers with components
Only use controllers at the top-level for receiving data from the route, and use Ember.Controller instead of Ember.ArrayController or Ember.ObjectController
Fetch data in your route, and set it as normal properties on your top-level controller. Export an Ember.Controller, otherwise a proxy will be generated. You can use Ember.RSVP.hash to simulate setting normal props on your controller.

A number of tech news outlets, including WIRED, GigaOm, and MIT Technology Review, have recently started writing about Multipeer Connectivity ("one weird trick that the NSA hates"). Since the NSHipster article on the subject has been linked to in a lot of this coverage, I wanted to share some additional thoughts on the matter:

Multipeer Connectivity(http://nshipster.com/multipeer-connectivity/) represents a significant shift in the opposite direction of how we conventionally think about mobile applications. Nearly every app on your phone operates in a client-server model, with the device making requests to remote cloud services to send and receive messages, photos, and videos. The [
