Kaltxรฌ Emberistas! ๐Ÿน

This week: the EmberFest 2019 CFP is now open ๐Ÿ“, build a GitHub Gist clone in Octane โ›ฝ๏ธ, RFC proposing deprecation of mouseenter + mouseleave Ember Events ๐Ÿ, and last, but not least, an interview with Yehuda Katz ๐ŸŽ™๏ธ!


EmberFest 2019 CFP is now open! ๐Ÿ“

EmberFest โ€“ the European Community Ember Conference โ€“ will be held at Mogens Dahl in Copenhagen this year from October 17-18, 2019. They have recently announced that the CFP is now open with a deadline at August 1, 2019.

EmberFest is looking for a wide range of talks, from in-depth technical talks to broader talks covering other aspects of software development. While Ember-related is best, EmberFest is open to considering talks that cover more general software / tech related topics that would be of interest to Ember developers.

Submit your talk today!


Build a GitHub Gist Clone in Octane โ›ฝ๏ธ

In this free video tutorial, Program with Erik and Jeffrey Biles pair program on building a simplified GitHub Gist clone in Octane. Jeffrey explains how Octane is a set of features bundled together to create a new programming experience. This video is geared toward beginners, folks coming from other frameworks, or people who are coming back to Ember after awhile! Share it with a friend?

In addition to using the Octane blueprint, the tutorial makes use of ember-prism and ember-animated. Check out the recording and use the GitHub repo as a reference to code along at home.


Ember Event Dispatcher Clean Up for Several Mouse Events ๐Ÿ๐Ÿ’ฅ

Since the early beginnings of Ember, the Ember Event Dispatcher handled the delegation of browser events in an application. But some events are harder to delegate to the Dispatcher than others. In particular, the mouseenter๐Ÿ•ณ โฌ…๏ธ๐Ÿ and the mouseleave ๐Ÿ•ณ๐Ÿโžก๏ธ events need to be handled differently because they do not bubble up - a characteristic that Ember's Event Dispatcher usually relies on for event delegation.

In a new RFC, the writer of RFC #386 is back with a proposal to reduce the overhead of event handling for these rarely used event types. In his proposal, @simonihmig suggests the deprecation of mouseleave and mouseenter events in Ember's Event Dispatcher in favor of using native event listeners.

Read more about the motivation and the transition path for the proposed change in the original RFC and be sure to leave your questions, thoughts or suggestions in the comments below! โœ๏ธ
