yarn add aria-data
const ariaData = require('aria-data');

This dataset uses URLs such as https://www.w3.org/TR/wai-aria-1.1/#alert
as
reference IDs for entities. For example:
{
"ref": "https://www.w3.org/TR/wai-aria-1.1/#aria-activedescendant",
"name": "aria-activedescendant",
"description": "Identifies the currently active element (...)",
"valueType": "https://www.w3.org/TR/wai-aria-1.1/#valuetype_idref"
}
This dataset has the following interface:
export default interface {
roles: {
[ref: string]: {
ref: string,
name: string,
description?: string,
abstract: boolean,
superClassRoles: Array<Ref>,
attributes: Array<Ref>,
},
},
valueTypes: {
[ref: string]: {
ref: string,
name: string,
description?: string,
},
},
attributes: {
[ref: string]: {
ref: string,
name: string,
description?: string,
valueType: Ref,
values?: Array<{
value: string,
isDefault: boolean,
description?: string,
}>
},
},
}
const { roles, valueTypes, attributes } = require('aria-data');
const ROLES_ARR = Object.keys(roles).map(ref => roles[ref]);
function findRole(roleName) {
return ROLES_ARR.find(role => role.name === roleName);
}
function getAttrs(role) {
function traverse(role) {
return role.superClassRoles.reduce((attrs, ref) => {
return attrs.concat(traverse(roles[ref]));
}, role.attributes);
}
return traverse(role).map(ref => attributes[ref].name);
}
let alert = findRole('alert');
let alertAttrs = getAttrs(alert);
// ['aria-expanded', 'aria-atomic', 'aria-busy', 'aria-controls', ...]
// ['aria-atomic', 'aria-busy', ...]
