ESLint flat config (v9+) for Merchant Center customizations.

## Requirements

- ESLint 9.x or higher
- Node.js 18.x, 20.x, or >=22.0.0

## Migrations

See the [migrations/](./migrations/) directory for version-specific upgrade guides. Each file is structured for both human and AI-assisted migration.

## Install

```bash
pnpm add -D eslint @commercetools-frontend/eslint-config-mc-app
```

## Usage

Create an `eslint.config.js` file in your project root:

```js
// eslint.config.js
const mcAppConfig = require('@commercetools-frontend/eslint-config-mc-app');

module.exports = [
  ...mcAppConfig,
  // Add your custom config overrides here
];
```

> **Note**: This package uses ESLint's flat config format introduced in ESLint 9. If you're migrating from ESLint 8, you'll need to replace your `.eslintrc.js` file with `eslint.config.js`.
