We will be starting with Ember 3.0 to automatically get the ~10 kb savings the removal of deprecations gives us. I have setup this example app and added some bloated and non-performant things to it. I highly recommend following along with the official repo and just making these changes in your other apps later, but if you would like to try to work in a different app, feel free to, but we may not be able to offer as much support if things go wrong.
npm install -g lighthouse
npm install -g broccoli-concat-analyser
The steps and exercises live in the app itself. If you would like to refer to something deployed, you can head to https://ember-performance-workshop.netlify.com/ to see the app deployed, before any changes or exercises have been completed. The steps live on the pages there.
