What is axe-core?

The axe-core npm package is a library for accessibility testing. It allows developers to automatically test their HTML for common accessibility issues using a variety of technologies including JavaScript, React, Angular, Vue, and more. The package can be used in different environments like web browsers, Node.js, and continuous integration systems.

What are axe-core's main functionalities?

Accessibility testing in browser

This code sample demonstrates how to run accessibility tests on the current document in a web browser. The results are logged to the console.

axe.run(document, function(err, results) {
  if (err) throw err;
  console.log(results);
});

Integration with testing frameworks

This code sample shows how axe-core can be integrated with Jest testing framework using jest-axe to ensure that a rendered HTML snippet is accessible.

const { axe, toHaveNoViolations } = require('jest-axe');

test('ensures .foo element is accessible', async () => {
  const render = () => '<div class="foo">bar</div>';
  const html = render();
  expect(await axe(html)).toHaveNoViolations();
});

Command-line accessibility testing

This code sample illustrates how to use axe-core with axe-cli for command-line accessibility testing of a given URL.

const axe = require('axe-core');
const { run } = require('axe-cli');

run(axe, { url: 'http://example.com' }, (err, results) => {
  if (err) throw err;
  console.log(results);
});
