Accessibility Helpers

A lightweight library for improving accessibility in React applications. This package includes tools and hooks to simplify focus management, detect accessibility issues, and dynamically apply ARIA attributes.

Features

• Focus Management:

  • useAccessibleFocus: Automatically sets focus on an element when a condition is met.

• Accessibility Issue Detection:

  • checkAccessibility: Scans the DOM for accessibility violations using axe-core.

• Dynamic ARIA Attributes:

  • addAriaAttributes: Dynamically adds ARIA attributes to elements for better screen reader support.

Installation

Install the package via npm:

npm install react-access-helper

Or with Yarn:

yarn add react-access-helper

Usage

1. Focus Management with useAccessibleFocus

Automatically manage focus for elements to enhance keyboard navigation.

import React, { useRef } from "react";
import { useAccessibleFocus } from "react-access-helper";

const App = () => {
  const ref = useRef<HTMLButtonElement>(null);

  // Focus the button when the condition is true
  useAccessibleFocus(ref, true);

  return <button ref={ref}>Click Me</button>;
};

export default App;

2. Detect Accessibility Issues with checkAccessibility

Identify and debug accessibility issues during development.

import React, { useEffect } from "react";
import { checkAccessibility } from "react-access-helper";

const App = () => {
  useEffect(() => {
    const rootElement = document.getElementById("root");
    if (rootElement) {
      checkAccessibility(rootElement).then((results) => {
        console.log("Accessibility Issues:", results.violations);
      });
    }
  }, []);

  return <div id="root">Hello, World!</div>;
};

export default App;

3. Add Dynamic ARIA Attributes

Simplify adding ARIA attributes programmatically.

import { addAriaAttributes } from "react-access-helper";

const element = document.getElementById("example");
if (element) {
  addAriaAttributes(element, {
    label: "Accessible Element",
    describedby: "description",
  });
}
