litepa11y v0.6.15

litepa11y

Litepa11y is a high performance web accessibility issue detector.

You need to have an active instance of puppeteer running with a connection to get started. This library does not open a new browser for you.

Getting Started:

npm i litepa11y --save

Requires node ^13

import { pa11y } from "litepa11y"

pa11y("https://example.com/").then((results) => {
  // Do something with the results
});

litepa11y resolves with an array of objects, containing details about the page and accessibility issues:

{
    documentTitle: 'The title of the page',
    pageUrl: 'The URL that litepa11y was run against',
    issues: [
        {
            code: 'WCAG2AA.Principle1.Guideline1_1.1_1_1.H30.2',
            context: '<a href="https://example.com/"><img src="example.jpg" alt=""/></a>',
            message: 'Img element is the only content of the link, but is missing alt text. The alt text should describe the purpose of the link.',
            selector: 'html > body > p:nth-child(1) > a',
            type: 'error',
            typeCode: 1,
            recurrence: 0
        }
        // more issues...
    ]
}

Runners

litepa11y supports multiple test runners which return different results. The built-in test runners are:

• axe: run tests using aXe-core.
• htmlcs (default): run tests using HTML CodeSniffer
