a11y-fix "**/*.html" --report --output a11y-report.html

📖 Usage

CLI Command

a11y-fix <patterns...> [options]

Arguments

<patterns...> - File patterns to scan (e.g., "**/*.html", "**/*.jsx")

Options

-f, --fix - Automatically fix issues where possible
-r, --report - Generate a report file
-o, --output <path> - Output path for report (default: a11y-report.html)
-c, --config <path> - Path to config file

Programmatic API

import { AccessibilityAutoFixer } from 'accessibility-auto-fixer';

const scanner = new AccessibilityAutoFixer({
  fix: true,
  report: true,
  reportPath: 'a11y-report.html',
  ignore: ['**/node_modules/**'],
});

const results = await scanner.scanFiles(['**/*.html', '**/*.jsx']);

results.forEach((result) => {
  console.log(`File: ${result.file}`);
  console.log(`Issues: ${result.total}`);
  console.log(`Fixed: ${result.fixed}`);
});

⚛️ React & TypeScript Usage

This package includes React hooks and components for runtime accessibility checking in your React applications.

📖 See USAGE_GUIDE.md for complete React integration examples

React Hooks

`useAccessibility` Hook

Check accessibility issues on a specific element:

import { useAccessibility } from 'accessibility-auto-fixer/react';
import { useRef } from 'react';

function MyComponent() {
  const ref = useRef<HTMLDivElement>(null);
  const { issues, checkAccessibility, clearIssues } = useAccessibility(ref, {
    enabled: true,
    checkOnMount: true,
    onIssueFound: (issues) => {
      console.log('Found issues:', issues);
    },
  });

  return (
    <div ref={ref}>
      <img src="/logo.png" /> {/* Missing alt text will be detected */}
      {issues.length > 0 && (
        <div>Found {issues.length} accessibility issues</div>
      )}
    </div>
  );
}

`useAccessibilityRef` Hook

Convenience hook that combines useRef with useAccessibility:

import { useAccessibilityRef } from 'accessibility-auto-fixer/react';

function MyComponent() {
  const { ref, issues, checkAccessibility } = useAccessibilityRef<HTMLDivElement>({
    enabled: process.env.NODE_ENV === 'development',
  });

  return <div ref={ref}>Content</div>;
}

React Components

`AccessibilityChecker` Component

Wrap your app or components to automatically check for accessibility issues:

import { AccessibilityChecker } from 'accessibility-auto-fixer/react';

function App() {
  return (
    <AccessibilityChecker enabled={true} showIssues={true}>
      <div>
        <h1>My App</h1>
        <img src="/logo.png" /> {/* Will show missing alt text */}
        <button onClick={handleClick}>Click me</button>
      </div>
    </AccessibilityChecker>
  );
}

`AccessibilityProvider` Component

Use context to share accessibility state across your app:

import { AccessibilityProvider, useAccessibilityContext } from 'accessibility-auto-fixer/react';

function App() {
  return (
    <AccessibilityProvider>
      <MyComponent />
    </AccessibilityProvider>
  );
}

function MyComponent() {
  const { issues, addIssue, clearIssues } = useAccessibilityContext();
  
  return (
    <div>
      <p>Total issues: {issues.length}</p>
      <button onClick={clearIssues}>Clear Issues</button>
    </div>
  );
}

Accessible Components

`AccessibleButton`

A button component that enforces accessibility best practices:

import { AccessibleButton } from 'accessibility-auto-fixer/react';

function MyComponent() {
  return (
    <AccessibleButton 
      ariaLabel="Close dialog" 
      onClick={handleClose}
      type="button"
    >
      Close
    </AccessibleButton>
  );
}

`AccessibleImage`

An image component that requires alt text:

import { AccessibleImage } from 'accessibility-auto-fixer/react';

function MyComponent() {
  return (
    <>
      {/* Required alt text */}
      <AccessibleImage 
        src="/logo.png" 
        alt="Company logo"
        width={200}
        height={100}
      />
      
      {/* Decorative image */}
      <AccessibleImage 
        src="/pattern.png" 
        alt=""
        decorative={true}
      />
    </>
  );
}

TypeScript Support

Full TypeScript support is included with type definitions:

import { 
  AccessibilityIssue,
  UseAccessibilityOptions,
  AccessibilityCheckerProps 
} from 'accessibility-auto-fixer/react';

{
  "fix": true,
  "report": true,
  "reportPath": "a11y-report.html",
  "ignore": [
    "**/node_modules/**",
    "**/dist/**",

📖 See USAGE_GUIDE.md for complete configuration options and examples

📊 Report Examples

Console Report

The tool provides a color-coded console output:

🔍 Accessibility Scan Report
============================================================

📄 src/components/Button.tsx
   Total Issues: 2 | Fixed: 1

   ❌ ERROR [missing-button-type] Line 15:10
      Button missing type attribute
      💡 Auto-fix available: Add type="button" to button

   ⚠️ WARNING [missing-aria-label] Line 23:5
      Interactive element missing aria-label or accessible text

HTML Report

Generate a beautiful HTML report with:

a11y-fix "**/*.html" --report

The HTML report includes:

Summary statistics
Detailed issue breakdown per file
Code snippets showing issues
Auto-fix suggestions
Color-coded severity indicators

🎯 Examples

Example 1: Fix all HTML files

a11y-fix "**/*.html" --fix

Example 2: Scan React components and generate report

a11y-fix "src/**/*.jsx" "src/**/*.tsx" --report --output reports/a11y.html

Example 3: Use with npm scripts

Add to your package.json:

{
  "scripts": {
    "a11y:check": "a11y-fix \"src/**/*.{html,jsx,tsx}\"",
    "a11y:fix": "a11y-fix \"src/**/*.{html,jsx,tsx}\" --fix",
    "a11y:report": "a11y-fix \"src/**/*.{html,jsx,tsx}\" --report"
  }
}

Then run:

npm run a11y:check
npm run a11y:fix
npm run a11y:report

🔧 Auto-Fixable Issues

The following issues can be automatically fixed:

✅ Missing alt text - Adds alt="" attribute (for decorative images)
✅ Missing button type - Adds type="button" attribute
✅ Missing lang attribute - Adds lang="en" to HTML element

Note: Some issues require manual intervention as they need context about your content (e.g., meaningful alt text for images).
