Advanced tools
Package description
The dom-accessibility-api package is a library that provides utility functions for querying and manipulating the accessibility tree of DOM elements. It allows developers to retrieve accessible names and descriptions, roles, and other properties related to accessibility, which are crucial for building web applications that are compliant with accessibility standards.
Getting the accessible name
This feature allows you to retrieve the accessible name of a DOM element, which is the name that screen readers will announce to users.
import { getAccessibleName } from 'dom-accessibility-api';
const element = document.getElementById('myElement');
const accessibleName = getAccessibleName(element);Getting the accessible description
This feature allows you to retrieve the accessible description of a DOM element, providing additional context to assistive technologies.
import { getAccessibleDescription } from 'dom-accessibility-api';
const element = document.getElementById('myElement');
const accessibleDescription = getAccessibleDescription(element);Getting the role
This feature allows you to get the computed role of a DOM element, which is used by assistive technologies to understand the purpose of the element.
import { getRole } from 'dom-accessibility-api';
const element = document.getElementById('myElement');
const role = getRole(element);aria-query is a package that provides maps of ARIA roles, states, and properties to use with DOM elements. It is similar to dom-accessibility-api in that it helps with accessibility concerns but does not provide functions to directly retrieve accessible names or descriptions.
ally.js is a JavaScript library to help modern web applications with accessibility concerns. It provides a higher-level API compared to dom-accessibility-api and includes features for focus handling, keyboard interaction, and more.
Changelog
0.4.6
f7c1981 #288 Thanks @eps1lon! - Drop node 13 support
We only stopped testing. Probability of breakage should be very low.
New policy:
Only active node versions are supported. Inactive node versions can stop working in a SemVer MINOR release.
fa53c51 #210 Thanks @eps1lon! - Implement accessbile description computation
import { computeAccessibleDescription } from "dom-accessibility-api";
const description = computeAccessibleDescription(element);
Warning: It always considers title attributes if the description is empty.
Even if the title attribute was already used for the accessible name.
This is fails a web-platform-test.
The other failing test is due to aria-label being ignored for the description which is correct by spec.
It's likely an issue with wpt.
The other tests are passing (13/15).
Readme
Computes the accessible name or description of a given DOM Element. https://w3c.github.io/accname/ implemented in JavaScript for testing.
$ yarn add dom-accessibility-api
import {
computeAccessibleName,
computeAccessibleDescription,
} from "dom-accessibility-api";
I'm not an editor of any of the referenced specs (nor very experience with using them) so if you got any insights, something catches your eye please open an issue.
WARNING: Only active node versions are supported. Inactive node versions can stop working in a SemVer MINOR release.
