Yesterday I published an updated version of the Rock and Roll with Ember.js book. The app now runs on 2.8 (Ember CLI, Ember and Ember Data) and, as usual, there are a few other changes.
The biggest of these was updating the Deployment chapter. PageFront seems defunct so I replaced it with Surge. Above that I also updated the section on deploying (to S3) with ember-cli-deploy as things have changed quite a bit.
PSA: Ember 2.9 will bring the long-awaited new rendering engine, Glimmer 2!
I already went ahead and updated the app to 2.9.beta to give it a whirl.
The results were pretty jaw-dropping:
My app.js size after upgrading the Rock and Roll #Ember app to use Glimmer 2 (so from 2.8.1 to 2.9.0-beta.2) went from 233K to 79K 😮— Balint Erdi (@baaz) September 16, 2016
I encourage you to try switching your app to Glimmer 2 and see if you encounter any problems.
