jscs-ember-deprecations
This is a JSCS plugin to include errors for features that are deprecated in Ember.js
Installation
npm install jscs-ember-deprecations --save-dev
You'll also need to tell JSCS to load the plugin. Modify your .jscsrc
file to include
"plugins": [
"jscs-ember-deprecations"
],
"disallowObjectController": true,
"disallowInstanceInInitializer": true,
"disallowPrototypeExtension": true,
"disallowAtEachLeafNode": true,
// ...
If you invoke JSCS with --fix
(see http://jscs.info/overview#cli) some deprecation errors can be fixed automatically.

Why
Migrating to a newer Ember version can be tricky if you haven't already gone back and removed all uses of deprecated features. Instead, this plugin intends to enable a migration path in a codebase, where developers can be warned when they use deprecated features.
A sample use case is to:
- Use a tool like Lint Review to automagically annotate pull requests. Developers will be warned if they're using a feature that is deprecated. Put these "aspirational" rules in
.toolbot_jscsrc
- Use
broccoli-jscs
so that JSCS gets run at the same time you're running unit tests. Put rules that are "mandatory" in your codebase's.jscsrc
. Any violations of those rules will result in the test suite failing.
This way a codebase can be gradually brought into compliance over time.
