eslint-plugin-ember-rules

A set of ESLint rules for Ember applications.

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-ember-rules:

$ npm install eslint-plugin-ember-rules --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-ember-rules globally.

Usage

Add ember-rules to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "ember-rules"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "ember-rules/destructure-namespaces": [2, ["Ember", "DS"]]
    }
}

Supported Rules

• destructure-namespaces - Ensure that properties from the configured namespaces are assigned to variables before they are used.

• no-function-prototype-extension-calls - Prevent the use of Ember's methods property, observes, and observesBefore which are added to the function prototype. A common example of a violation would be this deprecated syntax:

  Ember.Object.extend({
    name: function() {
      return this.get('firstName') + this.get('lastName');
    }.property('firstName', 'lastName')
  })
