👋 Emberistas! 🐹

The Road to Ember 4.0, introducing a11y-disabled-modifier, Emberliners talks, and get your update for ember-engines 0.8.18.

The Road to Ember 4.0 🛣

Announcing Ember 4.0: Ember 4.0 will be released around September 20th. Ember 4.4 will be the first LTS candidate of the 4.x series.
Whats in a 4.0?: As a major version of Ember, there are no new features. This sections discusses the removal of deprecated APIs. For example, Ember.Logger is removed in favor of native console APIs. Also, sendAction is removed in favor of calling closure actions like any other callback.
Planning your upgrade to 4.0: Consider using the ember-cli-deprecation-workflow addon as part of your upgrade process.
Contributing to Ember 4.0: Join us on Discord in the #dev-ember-js, #dev-ember-data, #dev-ember-cli, or #dev-ember-learning channels to find out how you can contribute.

Please check out the detailed post in full for more details on how you can prepare for your upgrade!

We're looking forward to working with the community on Ember 4.0 and on the opportunities beyond it. As always we appreciate your support, your trust, and our common partnership.

Introducing the a11y-disabled-modifier Modifier 💚

Inspired by the CSSTricks blog post on Making Disabled Buttons More Inclusive, Chris Krycho (@chriskrycho) created the a11y-disabled-modifier addon.

The blog post argues against the disabled attribute in <button> in favor of the aria-disabled attribute since it does not prevent clicking and focusing on the button which is useful when you are navigating the site using the Tab key.

This modifier implements accessible and usable button-disabling by adding aria-disabled="true" to the target element when the when named argument is truthy. It will also stop any clicks on the button from propagating and ensures form submission does not trigger.

<form {{on "submit" this.submit}}>
  <label>some text: <input type='text' /></label>
  <button type='submit' {{disabled when=this.isInvalid}}>submit</button>
</form>

Try it out today by running ember install a11y-disabled-modifier on your Ember app!
