ember-cli-eslint

🔴 DEPRECATED 🔴

Please use ESLint directly instead.

More info / background:

Installation

ESLint 4 (for Node 4 and above):

ember install ember-cli-eslint@4

ESLint 3 (for Node 4 and above):

ember install ember-cli-eslint@3

ESLint 2 (for Node 0.10 and above):

ember install ember-cli-eslint@2

After installation, an .eslintrc.js file will be placed in both the root of
your project and the /tests directory.

Furthermore, a .eslintignore file can be used to exclude files from
linting while the linter is running. Its syntax is identical to
.gitignore files.

Disabling JSHint

Congratulations! You’ve made the leap into the next generation of JavaScript
linting. At the moment, however, ember-cli defaults to generating
applications and addons with a jshint configuration.

If you notice the two awkwardly running side by side, click here!

#### ember-cli >= 2.5.0

As of ember-cli v.2.5.0,
jshint is provided through its own ember-cli-jshint addon.
Running npm uninstall --save-dev ember-cli-jshint, in addition to removing
any .jshintrc files from your project should guarantee that its behavior
is disabled.

#### ember-cli < 2.5.0

Controlling linting is a bit trickier on versions of ember-cli prior to
2.5.0. Within your ember-cli-build.js file, ember-cli-qunit or
ember-cli-mocha can be configured to have their default linting process
disabled during:

javascript
module.exports = function(defaults) {
  const app = new EmberApp(defaults, {
    'ember-cli-qunit': {
      useLintTree: false
    }
  });
};

javascript
module.exports = function(defaults) {
  const app = new EmberApp(defaults, {
    'ember-cli-mocha': {
      useLintTree: false
    }
  });
};

Alongside this setting, the hinting property can then be used to
enable/disable globally:

javascript
const isTesting = process.env.EMBER_ENV === 'test';

module.exports = function(defaults) {
  const app = new EmberApp(defaults, {
    hinting: !isTesting,
  });
};

Usage

ESLint will be run by ember-cli-qunit or ember-cli-mocha automatically
when you run ember test. If ESLint is not being run automatically, try
updating your ember-cli and/or ember-cli-qunit/ember-cli-mocha
dependencies.

Configuration

ember-cli-eslint can be configured through the eslint key in your
ember-cli-build.js file:

let app = new EmberApp(defaults, {
  eslint: {
    testGenerator: 'qunit',
    group: true,
    rulesDir: 'eslint-rules',
    extensions: ['js'],
  }
});

testGenerator is automatically detected if ember-qunit/ember-cli-qunit
or ember-mocha/ember-cli-mocha are used, but can also be set to qunit
and mocha manually.
group can be set to false to go back to the previous behavior where
every generated test was contained in its own separate module.
rulesDir is the name of the directory for your custom eslint rules.
It defaults to eslint-rules.
extensions is an array containing the file extensions to lint. If you want to lint JavaScript and TypeScript files for example it should be set to ['js', 'ts']. NOTE: If you add Typescript files @typescript-eslint/parser has to be installed and specified as the parser. For more information take a look at the @typescript-eslint/parser

On Build Files

Please note that if you are using this to lint files which are part of the build
process (ie. index.js, ember-cli-build.js, config/), whether in an application or
as part of an addon, they will not be linted. It is recommended that eslint is
setup separately to lint these files and can be setup as an npm script and run as
part of a CI process.
