Comprehensive Monitoring

import asyncio
from unacode.orchestrators import AccessibilityComplianceOrchestrator

async def monitor_accessibility():
    orchestrator = AccessibilityComplianceOrchestrator()

    # Configure continuous monitoring
    sites = [
        "https://app.example.com",
        "https://marketing.example.com",
        "https://support.example.com"
    ]

    for site in sites:
        report = await orchestrator.run_accessibility_audit(
            url=site,
            standards=["wcag_2_1_aa", "ada"],
            test_types=["automated", "color_contrast", "keyboard", "screen_reader"]
        )

        print(f"Site: {site}")
        print(f"Compliance Score: {report.compliance_score}%")
        print(f"Critical Issues: {report.critical_issues}")

        if report.critical_issues > 0:
            # Send alert to team
            await send_accessibility_alert(site, report)

Issue Types

Critical Issues

  • Missing alt text on informative images
  • No keyboard access to interactive elements
  • Very low contrast ratios (< 2:1)
  • Missing form labels for required inputs

Major Issues

  • Insufficient contrast ratios (< 4.5:1 for normal text)
  • Focus not visible on keyboard navigation
  • Missing ARIA labels for complex widgets
  • Improper heading structure (skipped levels)

Moderate Issues

  • Suboptimal color combinations meeting minimum but not ideal
  • Missing skip links for long navigation
  • Inconsistent focus order in complex layouts
  • Limited ARIA descriptions for context

Integration Options

WebSocket Updates

const ws = new WebSocket('ws://localhost:8080/ws');
ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  if (data.type === 'audit_complete') {
    console.log(`Audit completed: ${data.data.compliance_score}% score`);
    updateAccessibilityDashboard(data.data);
  }
};

Webhook Notifications

{
  "webhook_url": "https://myapp.com/accessibility-webhook",
  "events": ["audit_complete", "violation_detected"],
  "authentication": {
    "type": "bearer",
    "token": "your_auth_token"
  }
}

Best Practices

1. Regular Auditing

  • Run audits on all major releases
  • Monitor high-traffic pages weekly
  • Test across multiple devices and browsers

2. Severity Prioritization

  • Address critical issues immediately
  • Plan major issues for next sprint
  • Track moderate issues for future improvements

3. Team Integration

  • Include accessibility in definition of done
  • Train developers on common issues
  • Establish accessibility design system

4. Continuous Improvement

  • Track compliance scores over time
  • Set up automated alerts for regressions
  • Regular accessibility training sessions

Dashboard Features

The integrated dashboard provides:

  • Real-time Compliance Scores - Track improvements over time
  • Issue Breakdown - Categorize and prioritize violations
  • Remediation Guidance - Step-by-step fix instructions
  • Team Analytics - Track team progress and training needs
  • Trend Analysis - Identify patterns and improvement opportunities
