// Replace your-framework with the framework you are using (e.g., react-webpack5, vue3-vite)
import type { StorybookConfig } from '@storybook/your-framework';

const config: StorybookConfig = {

    '@storybook/addon-essentials'
    'storybook-addon-datalayer-watcher', // 👈 register the addon here

};

export default config;

## Usage

This addon allows you to debug GTM dataLayer events in Storybook.

If your component pushes to the dataLayer array (directly or using a library), you can interact with it in Storybook and see the GTM events it triggers.
