Issue Summary

In Safari 13.0.4 on macOS 10.15.2, the 'Upload routes YAML' button triggers a file browser that only allows selection of files ending in .yml. These are not accepted by the application, which requires a .yaml extension. This results in routes not being uploadable with Safari.

To Reproduce

1. In Safari, click the 'Upload routes YAML' button in Labs.

This doesn'

While investigating #18075, I noticed a minor issue, that persists even after the change to WeakMap in #18091, because of the lazy evaluation

class Foo {
  @service someService;

  @tracked someProp = this.someService.serviceProp;
}

Assume Foo gets created by a container lookup or get manually called
setOwner on.

Intuitively I would expect the above code to work.

Looking at #9009 there are a lot of great changes

• replacing ember-cli-eslint with plain old eslint
• running commands in parallel
• a nice convention of lint:* and test:* npm scripts

Great work all round 🎉

I looked at adopting this approach in our projects. We're not using travis for CI, so that's one difference.. but we do run npm test (technically yarn test) in CI, which

The ember-data core team and contributors would like to modernize the API documentation by EmberConf 2020. Modernizing entails writing a package overview, revising inline documentation and auditing code snippets for accuracy. I broke the sections of this quest issue out by logical aspects of ember-data's API. Each section will list individual tasks.

[History](https://github.com/emberjs/data/i

We've integrated ember-simple-auth to our application. Following, the documentation, we load the user from the sessionAuthenticated callback :

// app/routes/application.js
import Ember from 'ember';
import ApplicationRouteMixin from 'ember-simple-auth/mixins/application-route-mixin';

const { service } = Ember.inject;

export default Ember.Route.extend(ApplicationRouteMixin

When developing locally, there are many YUIDoc warnings that say "Missing item type", like so:

WARNING:  ember-table/-private/utils/array.js:4: Missing item type
Genericizes `objectAt` so it can be run against a normal array or an Ember array
WARNING:  ember-table/-private/utils/array.js:32: Missing item type

We should add some docs to let people know to write normal Ember tests and how we would recommend testing the electron parts.

Replace with import { DEBUG } from '@glimmer/env';, see emberjs/ember.js#18912.

I believe its time for a demo page / docs overhaul. A lot of issues have been opening up because of either lack of documentation or it just being confusing. This issue has been opened to track what needs to be changes / added.

• General cleanup (spelling / grammar mistakes)
• Add some better examples
• Add note on testing (i.e. needs: ['validator:presence'])
• Maybe restructu
