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:

``sh
npm i litepa11y --save
`

Requires node ^13

`js
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:

`js
{
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: '',
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][axe].
- htmlcs` (default): run tests using [HTML CodeSniffer][htmlcs]
