Thoughtbot offer a tool called HoundCI that does this for JS, ruby, coffeescript and SASS (SCSS). They charge $12&#x2F;month for private repos and it&#x27;s free for open source.<p>It&#x27;s designed to check your github pull requests.
Haven&#x27;t used it but looks pretty nice.
They provide style guides for each language that your free to customize.<p><a href="https:&#x2F;&#x2F;houndci.com" rel="nofollow">https:&#x2F;&#x2F;houndci.com</a>
