⚠️ BREAKING CHANGE

This release converts the package to ESM-only and TypeScript. Projects using require() will need to migrate to ESM or use dynamic imports.

After this release CommonJS is no longer supported. See ESM Module FAQ.

Migration Guide

For consumers using CommonJS (require):

// ❌ No longer works
const { passesWcagAa } = require('passes-wcag')

// ✅ Option 1: Convert to ESM
import { passesWcagAa } from 'passes-wcag'

// ✅ Option 2: Use dynamic import
const { passesWcagAa } = await import('passes-wcag')

For consumers already using ESM:

No changes needed - the package now properly exports ESM with full TypeScript types.
