Installation

First, install the package.

npm install --save-dev storybook-addon-datalayer-watcher

Then, register it as an addon in .storybook/main.js.

// .storybook/main.ts

// 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 = {
  // ...rest of config
  addons: [
    '@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.
