ESLinting for Ember CLI apps, ESLint provides a scriptable mechanism for checking applications against a strict set of rules.

• ember install ember-cli-eslint
• This will create a .eslintrc file in your project directory setup with the correct parser.

babel-eslint parser will solve any new ECMA missing functionality in ESLint.

Adding the following to your parser after installing will solve this issue:

    "parser": "babel-eslint",

• ember install ember-cli-eslint

You may want to generate tests that pass/fail based on the eslint result.

You can pass a testGenerator function to EmberApp. Use the eslint option.

Example:

// ember-cli-build.js (or Brocfile.js on older versions of ember-cli)

var path = require('path');
var EmberApp = require('ember-cli/lib/broccoli/ember-app');
// `npm install --save-dev js-string-escape`
var jsStringEscape = require('js-string-escape');

var app = new EmberApp({
  eslint: {
    testGenerator: eslintTestGenerator
  }
});

function render(errors) {
  if (!errors) { return ''; }
  return errors.map(function(error) {
    return error.line + ':' + error.column + ' ' +
      ' - ' + error.message + ' (' + error.ruleId +')';
  }).join('\n');
}

// Qunit test generator
function eslintTestGenerator(relativePath, errors) {
  var pass = !errors || errors.length === 0;
  return "import { module, test } from 'qunit';\n" +
    "module('ESLint - " + path.dirname(relativePath) + "');\n" +
    "test('" + relativePath + " should pass ESLint', function(assert) {\n" +
    "  assert.ok(" + pass + ", '" + relativePath + " should pass ESLint." +
    jsStringEscape("\n" + render(errors)) + "');\n" +
   "});\n";
}

// Mocha test generator
function eslintTestGenerator(relativePath, errors) {
  var pass = !errors || errors.length === 0;
  return "import { describe, it } from 'mocha';\n" +
    "import { assert } from 'chai';\n" +
    "describe('ESLint - " + path.dirname(relativePath) + "', function() {\n" +
    "  it('" + relativePath + " should pass ESLint', function() {\n" +
    "    assert.ok(" + pass + ", '" + relativePath + " should pass ESLint." +
    jsStringEscape("\n" + render(errors)) + "');\n" +
   "  });\n});\n";
}

npm install -g phantomjs;
ember test

The tests are using the dummy app to output tests.
