# Criteo Tracking Plugin for Nuxt.js

This plugin integrates Criteo's tracking events into a Nuxt.js application, allowing you to easily track user interactions such as page visits, product views, cart actions, and transactions.

## Installation

Install the plugin using npm:

```bash
npm install @hevelop/nuxt-criteo-onetag
```

## Usage

1. Add the plugin to your `nuxt.config.js` file.

   ```javascript

     ],
     criteoOnetag: {
       enabled: true,
     },
   };
   ```

2. Use the `$criteo` functions to trigger various tracking events in your app.
