Getting Started

Install this plugin with npm install access-sniff --save

ES5

 var AccessSniff = require('access-sniff');

AccessSniff
  .default(['**/*.html'], options)
  .then(function(report) {
    AccessSniff.report(report, reportOptions);
  });

ES6

 import AccessSniff, { reports as AccessReports } from 'access-sniff';

AccessSniff(['**/*.html'], options)
  .then(report => AccessReports(report, reportOptions));

CLI

npm install access-sniff -g
sniff test/**/*.html -r json -l reports

AccessSniff can test both locally hosted files and websites.

sniff http://statamic.com/ -r json -l reports

Options

You can pass the following options

Accessibility Level

accessibilityLevel is a string

 options: {
  accessibilityLevel: 'WCAG2A'
}

Levels are WCAG2A, WCAG2AA, WCAG2AAA, and Section508

Accessibilityrc

You can create an .accessibilityrc file in your project to set options:

 {
  "ignore": [
    "WCAG2A.Principle2.Guideline2_4.2_4_2.H25.1.NoTitleEl",
    "WCAG2A.Principle3.Guideline3_1.3_1_1.H57.2"
  ]
}

Ignore

ignore is an array

You can ignore rules by placing them in an array outlined below.

 options: {
  ignore: [
    'WCAG2A.Principle2.Guideline2_4.2_4_2.H25.1.NoTitleEl'
    'WCAG2A.Principle3.Guideline3_1.3_1_1.H57.2'
  ]
}

Rules will also match to remove and entire set.

WCAG2A.Principle2.Guideline2_4.2_4_2.H25.1 will ignore WCAG2A.Principle2.Guideline2_4.2_4_2.H25.1.NoTitleEl

Verbose output

verbose is a boolean

 options: {
  verbose: false
}

Output messages to console, set to true by default

Force

force is a boolean, defaults to false

 options: {
  force: true
}

Continue running in the event of failures.
You can catch failures from the promise as below:

 AccessSniff(['**/*.html'], options)
.then(report => AccessReports(report, reportOptions));
.catch(error => console.error(error))

 options: {
  browser: false

AccessSniff uses jsDom as the default, setting this to true will use PhantomJs instead
