#### ESM (Recommended)
Add this to your eslint.config.js:
``javascript
import eta from '@jeffcaradona/eslint-plugin-eta'

export default [
{
files: ['*/.eta'],
plugins: {
eta
},
processor: 'eta/eta'
}
]
`

#### CommonJS (v0.3.0+)
> Available in v0.3.0 and later

Add this to your eslint.config.cjs:
`javascript
const eta = require('@jeffcaradona/eslint-plugin-eta')

module.exports = [
{
files: ['*/.eta'],
plugins: {
eta
},
processor: 'eta/eta'
}
]
`

Compatibility Matrix

| Node Version | ESLint 9 | Eta v1-v4 |
|--------------|----------|-----------|
| 18.18.0 | ✅ | ✅ |
| 20.x | ✅ | ✅ |
| 24.x | ✅ | ✅ |

Troubleshooting

$3

If you're getting module resolution errors:

1. Ensure ESLint 9.x is installed: npm list eslint
2. Check Node.js version: Must be 18.18.0 or higher
3. Use flat config: ESLint 9 requires eslint.config.js (not .eslintrc.js)

$3

Run the full test suite to verify compatibility:
`bash
npm run test:prod
``

Test output includes linting, coverage, and all integration tests.
