klassijs A11y (Accessibility) Validator

Overview

klassijs-a11y-validator is a powerful tool designed to automate the verification of accessibility compliance for digital content, such as websites or applications. It helps developers and testers identify accessibility issues to ensure compliance with WCAG (Web Content Accessibility Guidelines) by programmatically testing elements against established standards (e.g., WCAG 2.0,2.1,2.2 on level A, AA and AAA). The function aims to ensure a more inclusive user experience, especially for individuals with disabilities, by identifying and helping resolve accessibility issues.

Key Features:

• Automated Accessibility Testing: Quickly validates the accessibility of web pages and applications.
• Compliance Checks: Ensures your application meets WCAG 2.0/2.1 guidelines and other accessibility standards.
• Detailed Reporting: Provides detailed reports on accessibility issues found during validation.
• Customizable Rules: Customize which accessibility rules you want to check based on your project's needs.
• Integration Ready: Easily integrate into your CI/CD pipelines for continuous accessibility validation.

Installation

You can easily install the a11y-validator using pnpm. Follow the steps below:

1. Open your terminal and navigate to your project directory.
2. Run the following command:

   pnpm add klassijs-a11y-validator

Usage

Here’s a guide on how to use the a11y-validator to check the accessibility of a webpage or application:

1. Import the Tool: Import the a11y-validator module into your project:

   const { a11yValidator } = require('klassijs-a11y-validator');

2. Run Accessibility Validation: Use the validate method to check a URL or HTML file for accessibility issues:

   async function runA11yValidation() {
       try {
           const results = await a11yValidator('https://yourwebsite.com');
           console.log('Accessibility Validation Results:', results);
       } catch (error) {
           console.error('Error during accessibility validation:', error);
       }
   }
   
   runA11yValidation();

   The validate method will return a detailed report containing any accessibility issues, such as missing alt text, color contrast problems, and other violations of accessibility guidelines.

3. Review the Report: The results will typically contain details such as:

   • The issue description
   • The severity level (e.g., critical, moderate, minor)
   • The location of the issue (e.g., the affected element)
   • Recommended fixes or actions
