grunt-achecker

Check HTML pages with achecker.

Getting Started

This plugin requires Grunt ~0.4.5

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-achecker --save-dev

You will also need a Web Service Id from AChecker.

Or... Better yet a Web Service Id from a custom/local installation. The source is available here atutor/AChecker. Once you have cloned the repository, follow the instructions in the AChecker Readme to install your own copy. It's easy. And you should be done in under 5 min.

By default, this task is configured to use the Public Api. But, please be nice and don't abuse the service.

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-achecker');

The "achecker" task

Contributing

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt. You will also need to create a webServiceId.json file from the provided example. The Gruntfile also assumes your local/custom host is accessible at http://achecker.localhost.
