The Ember Times – Issue No. 79

4 min read


Blein Vie Noa, Emberistas! 🐹🎆🎇

The new year starts off with loads of new RFCs!! Read more about suggested deprecations of Render route methods and selected ApplicationController properties 🈸! We also have a new RFC for a brand new look of emberjs.com, performance improvements 🏎 for the API Docs searcha new beta release of ember-cli-babel and an advanced testing exam for you!


The official Ember website is due for a new look and feel. That is why a new RFC proposes a completely new look 💅 for emberjs.com. A side effect of not having updated the look and feel of the website for some years is that for people who aren’t involved in the day-to-day of Ember development, it’s easy to miss just how well the framework has kept up over the years.

The redesign aims to modernize, update and improve all the things on the website so that the impression given to the general public matches reality.

There’s already a good discussion going on in the RFC comment section, and we would love to hear your thoughts as well.


Do you remember Route.render() and Route.renderTemplate()? You might not. In fact, these route methods have been less and less emphasized in the Ember learning story and are not even mentioned in the Ember Guides anymore. Although these APIs were useful in the past, nowadays a component-focused approach allows Ember developers to omit them entirely.

Therefore, a new RFC suggests the deprecation of Route#render and Route#renderTemplate. You can read more about the motivation behind it and how to replace these methods in your application in the original proposal.

Questions? Suggestions? Leave them right in the comments section of the RFC!


With the introduction of the Router Service it’s been easier than ever to check on the current app state, eg the name of the active route, anywhere in your application. This also means that the current ApplicationController#currentPath and ApplicationController#currentRouteName API has become obsolete.

A new RFC proposes the deprecation of these abundant properties in the future. Be sure to let your thoughts known in the proposal’s comments section!


Algolia search improvements

The integration with our search provider, Algolia that powers both Ember Guides and Ember API Docs has now become even more performant!

The work from our friends at Algolia unlocked a performance boost of the API docs search by as high as 285% for some countries in Europe! The map shows data centers where the API docs are currently stored and (on the right) the performance improvement for the top searching countries.


@pzuraq recently announced the release of ember-cli-babel@v7.3.0-beta.1!

The plugin ember-cli-babel uses Babel and babel-preset-env to allow us to use ES6 syntax within our Ember CLI project.

With the 7.3.0 beta release, the includeExternalHelpers option is now available. This option controls deduplicating the default Babel helper functions by putting them in a shared module and lowering the payload size.

To read more on the includeExternalHelpers check out the docs!


Ember’s testing story already makes testing incredibly approachable to developers, but what if it could bring even more to the table right from the start? Imagine being able to speed up your test suite with parallel testing or running tests in randomized order with an ember test command in your app.

A new RFC proposes an update to the default testing in Ember apps and addons by providing ember-exam – an Ember addon developers can already use for advanced testing strategies – built into Ember’s testing setup.

Be sure to read the full proposal and leave your thoughts in the comments below!
