###Source Github: https://github.com/estrat/eslint-config-ess
NPM: https://www.npmjs.com/package/eslint-config-ess

###Install npm install --save eslint-config-ess

###Grunt Configuration

1. Install grunt-eslint:

npm install --save-dev grunt-eslint

2. Create a new file in the grunt tasks folder, e.g. grunts/eslint.js.

mkdir -p grunts;
touch grunts/eslint.js

3. In this file, paste this code to register a grunt task:
   ``` 'use strict';

module.exports = function(grunt) {

	grunt.config('eslint', {
		options: {
			rulePaths: ['node_modules/eslint-config-ess/rules']
		},

		backend: {
			options: {
				config: 'eslint-config-ess/configs/backend.js'
			},
			src: [
				//file patterns here
			]
		},

		frontend: {
			options: {
				config: 'eslint-config-ess/configs/frontend.js'
			},
			src: [
				//file patterns here
			]
		}
	});

	grunt.loadNpmTasks('grunt-eslint');

};
```

4. Fill out the backend.src and frontend.src arrays.
5. Update gruntfile.js to include this configuration: ``` 'use strict';

var Pkg = require('./package.json');

module.exports = function(grunt) {

	grunt.initConfig({
		pkg: Pkg
	});

	grunt.loadTasks('grunts');
	
	grunt.registerTask('check', [
		'eslint'
	]);
	
	grunt.registerTask('lint', [
		'eslint'
	]);
	
	grunt.registerTask('build', [
		'check'
		//additional tasks here
	]);
	
	grunt.registerTask('default', [
		'check'
	]);
};
```

6. Test with grunt and grunt check.

###Sublime Text Configuration NOTE: This is a secondary helper; it will not catch as many errors as the grunt task above will.

1. Install Package Control if not already.
2. Open Package Control (⌘⇧P or CTRL+SHIFT+P).
3. Select Package Control: Install Package.
4. Install ESLint.
5. Repeat steps 2-3 and install SublimeLinter-contrib-eslint.
6. Create .eslintrc.js in the top-level directory of the repo (next to package.json):
   touch .eslintrc.js
7. Insert this code into .eslintrc.js (this will check only backend errors): ``` 'use strict';

function clone(obj) {
	return JSON.parse(JSON.stringify(obj));
}

var config = clone(require('eslint-config-ess').configs.backend);
if (config.rules['lowercase-require']) delete config.rules['lowercase-require'];
module.exports = config;
```
