Adapter for the HTML_CodeSniffer script

The easiest way is to keep karma-html_codesniffer as a devDependency in your package.json.

{
  "devDependencies": {
    "karma-html_codesniffer": "~1.0.0"
  }
}

You can simple do it by:

npm install karma-html_codesniffer --save-dev

Instructions on how to install karma can be found here.

Following code shows the default configuration...

// karma.conf.js
module.exports = function(config) {
  config.set({
    frameworks: ['html_codesniffer'],

    files: [
      '*.js'
    ]
  });
};
