πŸ‘‹ 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 πŸ›£

Matthew Beale (@mixonic) from the Ember Core Framework and Steering Committee teams, writes about The Road to Ember 4.0 on the official Ember blog.

  • 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 πŸ’š

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>
Enter fullscreen mode Exit fullscreen mode

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


Ember Berlin Meetup with 4 talks πŸ“½

Four amazing talks from our friends at Emberliners meetups are now available for binge watching!

  1. First up, is Embroider: from zero to route splitting in 3.5 weeks by Ben Demboski (@bendemboski) which explores what it takes to update a large desktop Ember app to use Embroider.

  2. Agathe Badia (@Agathebadia) shows her fascinating work on creating a Colorblindness emulator with Ember, an A11y project.

  3. Francesco Novy (@mydea) presents You could get used to this: Managing GraphQL data - a great primer on GraphQL in Ember.

  4. Lastly, Michael Klein (@levelbossmike) and Clemens Mueller (@pangratz) discuss On the development of reactive systems with Ember.js, providing an insightful view on approaching Ember development as a reactive system using ember-statecharts addon.

These talks give a great snapshot lots of exciting developments happening around the Ember community πŸ’—.
