JSHint

Making it easy to lint your JavaScript assets in any Rails 3.1+ application.

Installation

Add this line to your application's Gemfile:

group :development, :test do
  gem 'jshint'
end

And then execute:

$ bundle

Run the generator:

bundle exec rake jshint:install_config

Usage

To start using JSHint simply run the Rake task:

bundle exec rake jshint

This Rake task runs JSHint across all the JavaScript assets within the following three folders to ensure that they're lint free. Using that data it builds a report which is shown in STDOUT.

your-rails-project/app/assets/javascripts
your-rails-project/vendor/assets/javascripts
your-rails-project/lib/assets/javascripts

Configuration

JSHint has some configuration options. You can read the default configuration created by JSHint in your applications config folder.

# your-rails-project/config/jshint.yml
files: ['**/*.js']
exclude_paths: []
options:
  boss: true
  browser: true
  ...
  globals:
    jQuery: true
    $: true

For more configuration options see the JSHint documentation.

Excluding folders from being Linted

To exclude one of the above folders from being linted, you can define an array of exclude_paths within your configuration file.

files: ['**/*.js']
exclude_paths: ['vendor/assets/javascripts']
...

Rake integration

To use jshint in your default Rake config, just add it to the list of default tasks. For example, this configuration will run jshint in development or test environments.

# your-rails-project/Rakefile
if %w(development test).include? Rails.env
  task default: :jshint
endif
