crawlkit-runner-axe

aXe runner

This runner can be used with CrawlKit in order to audit a website with the aXe accessibility engine.

Install

npm install crawlkit-runner-axe --save

Example

const CrawlKit = require('crawlkit');
const AxeRunner = require('crawlkit-runner-axe');
 
const crawler = new CrawlKit('http://your/page');
// You could add a finder here in order to audit a whole network of pages
crawler.addRunner('aXe', new AxeRunner());
 
crawler.crawl()
    .then((data) => {
        console.log(JSON.stringify(data.results, true, 2));
    }, (err) => console.error(err));

Configuring the aXe runner

Passing options

You can pass an options object to the aXe runner like this:

crawler.addRunner('aXe', new AxeRunner(), {
  runOnly: {
      type: 'tag',
      values: ['wcag2aa']
    }
});

For a list of options and the structure of the options object, please consult the aXe API.

Defining context

You can define the context the aXe runner should use like this:

crawler.addRunner('aXe', new AxeRunner(), null, '.my-context');

By default, the context is document. Please bear in mind that only selector contexts work, as the code of the aXe runner itself runs in node.
