The Ember Times – Issue No. 72

4 min read

Kedu Emberistas! 🐹

We need Emberistas at JSConf EU, so submit a talk to the newly opened CFP! 🗣️ There’s an update to the RFC about RFCs 📜! You can also read about more informative Routes Watch, watch a tutorial on how to build a live updating league table ⚽️ in Ember 3.5 📹, or help upgrade the test coverage of official Ember projects! ✍️

JSConf EU, which will be held from June 1 – 2 2019 in Berlinhas officially opened their Call for Papers (CfP) for talks regarding JavaScript, the web, or a clever hack.

This is a good opportunity for us, as Ember developers, to showcase our work to the greater JavaScript community. Similar to the EmberConf process, the CfP starts out blind and later gets de-anonymized.

The call for speakers this year is open until December 23rd. JSConf’s sibling conference, CSSconf, even published a blog on How to write a great talk proposal for a tech conference.

”Pick the topic you feel most passionate about. This is your conference. ” is the JSConf EU saying so apply to be a speaker today!

There has been an update to the RFC (Request for Comments) about the RFC process itself. The RFC process has been crucial in defining the future of Ember and that is still the case. However, in the process of reading and merging all of these RFCs, the Core Team has discovered some shortcomings of the current RFC process as well as new requirements.

To solve some of these issues, the RFC proposes that new RFCs are assigned a Core Champion from the Core Team. It also suggests to merge ember-cli / rfcs into emberjs / rfcs.

There are more proposed solutions in the RFC, which we recommend you to read through and to leave a comment with your thoughts.

Have you ever wanted to track specific keywords for a particular route in your Ember app, but didn’t know how to do so in an elegant fashion? Have you tried to update the document.title of a page depending on the specific point of time at which a route was visited, but realized that this could not be done without some effort?

Then a brand-new Request for Comments (RFC) is for you! The proposal RouteInfo Metadata suggests a new way for reading and writing application-specific metadata to the corresponding RouteInfo object. For more context on which information routes currently provide, be sure to also check out the section about the RouteInfo type from the original RouterService RFC.

And finally, read the full RouteInfo Metadata proposal to learn more and leave your thoughts and questions in the comments below the proposal.

@GavinJoyce made an awesome tutorial where he demonstrates how to build a live updating league table in the latest Ember 3.5!! Code along with the video and you’ll use ember-cli-tailwind for styling, angle bracket invocation, shuffle from ember-composable-helpers (TIL), ember-math-helpers and more.

Check out to run the app and the repo for the source code. Our advice? Share the tutorial with a friend, whether they call it football or soccer…

So many contributors have been putting great effort into shipping features, improvements and bug fixes for important Ember projects recently, including the spick-and-span Ember Help Wanted App and our most be-loved (loved) Ember API Docs.

But with lots of new changes, also comes lots of responsibility for test coverage; and your help is needed! Help these amazing projects to get their test coverage up to par by writing unit, integration and acceptance test:
