React A11y

build status

Warns about potential accessibility issues with your React elements.



This is a WIP, feel free to explore, open issues, and suggest assertions :)


npm install react-a11y


In your main application file, require and call the module, you'll start getting warnings in the console as your app renders.

var a11y = require('react-a11y');
if (ENV === 'development') a11y(React);

You probably don't want to call it if you're in production, and better yet, alias the module to nothing with webpack in production.

If you want it to throw errors instead of just warnings:

a11y(React, { throw: true });

You can filter failures by passing a function to the filterFn option. The filter function will receive three arguments: the name of the Component instance or ReactElement, the id of the element, and the failure message. Note: If a ReactElement, the name will be the node type followed by the id (e.g. div#foo).

var commentListFailures = (name, id, msg) => {
  return name === "CommentList";

a11y(React, { filterFn: commentListFailures });

If you want to log DOM element references for easy lookups in the DOM inspector, use the includeSrcNode option.

a11y(React, { throw: true, includeSrcNode: true });

Some test are only relevant for certain device types. For example, if you are building a mobile web app, you can filter out desktop-specific rules by specifying a specific device type:

a11y(React, { device: ['mobile'] });

It's also possible exclude certain tests:

a11y(React, { exclude: ['REDUNDANT_ALT'] });


You can pass ReactDOM to a11y for React 0.14 compatibility.

a11y(React, { ReactDOM: ReactDOM });

Cleaning Up In Tests

Use the restoreAll() method to clean up mutations made to React. Useful if you are using React-a11y in your test suite.

beforeEach(() => a11y(React));
afterEach(() => a11y.restoreAll());
