Ember CLI Update which last week was brought in under the official ember-cli GitHub organization has gotten an update. It now has two new commands that will help you keep your apps updated and using the latest and greatest in Emberland. These new commands are --dry-run and --list-codemods.
The first, --dry-run, will give you a quick explanation of what running the update will do. For example running
on an app running Ember v2.15.1 would output: Would update from 2.15.1 to 3.1.2.
The second, --list-codemods, will give you a list of the available codemods along with more info about them.
Currently the codemods supported are: ember-modules-codemod, ember-qunit-codemod, ember-test-helpers-codemod, and es5-getter-ember-codemod. That last codemod helps your project use the native ES5 getters that were described up above.
A quick reminder that ember-cli-update has been accepted to be the official way to update Ember apps so if you aren't currently using it, now is a great time to start!
