Nuxt.js is a popular framework that provides official packages (modules) to integrate Google Tag Manager (GTM). The @nuxtjs/gtm module simplifies the process of integrating GTM into your Nuxt.js applications. By installing this module and configuring it in your nuxt.config.js file, you can begin using GTM to track user interactions, manage analytics scripts, and more without much heavy lifting.

Another module that was used in Nuxt.js applications for similar purposes is the @nuxtjs/google-gtag module. However, this has been identified as the older version (v1) and is now deprecated.

The @nuxtjs/gtm package provides flexibility to use GTM in such a way that tracking user-interactions and managing analytics scripts become a whole lot simpler. It offers extensive features like triggers, variables, data layer configurations, event tracking, and integration with router for tracking page views.

By invoking the $gtm.push() method, you can insert events into the configured layer without any hassle. Once the @nuxtjs/gtm module integrates into a Nuxt.js application, it also automatically sets up a Nuxt GTM data layer for interacting with Google Tag Manager.

While the key functionalities of @nuxtjs/gtm and @nuxtjs/google-gtag are similar, it's important to note that the older (@nuxtjs/google-gtag) module is deprecated, and developers are encouraged to transition to the newer (@nuxtjs/gtm) module.

Previously, developers used the @nuxtjs/google-gtag module. However, this is considered the old version (v1) and is no longer recommended for new projects. The @nuxtjs/gtm is the new version (v2) that is currently maintained by the Nuxt.js core team and is recommended for integrating GTM in Nuxt.js applications. It carries forward all the major functionalities of the predecessor but with improved performance, better community support, and compatibility with the latest technologies.

To transition from @nuxtjs/google-gtag to @nuxtjs/gtm, you would need to install the new module using npm or yarn, add it to the nuxt.config.js file, and update your scripts to utilize $gtm.push() method for interacting with the Data Layer.

In summary, while both modules served a similar purpose of integrating GTM into Nuxt.js, the newer @nuxtjs/gtm is the preferred choice due to its advanced features, simplified usage, and current maintenance by the Nuxt.js core team. In the next sections, we'll delve deeper into the actual integration process, exploring step-by-step instructions, best practices, and common troubleshooting methods.

In this section, we'll focus on implementing Google Tag Manager (GTM) in a Nuxt.js application. By the end of this guide, you'll have a solid understanding of how to install and configure the Nuxt.js Google Tag Manager module, include the necessary scripts in your nuxt.config.js file, and set up custom event triggers and data layer variables.

Installation of Nuxt.js GTM Module

The first step is to install the GTM module for your Nuxt.js project. You can easily achieve this by running the following command in your terminal:

npm install @nuxtjs/gtm

This command installs the @nuxtjs/gtm module, which is an official package maintained by the Nuxt.js team. Note that @nuxtjs/google-gtag is the deprecated version of this package, so we recommend using @nuxtjs/gtm instead.

Configuring and Including Script in nuxt.config.js file

Once the installation is complete, you'll need to configure the GTM module in your nuxt.config.js file. Add @nuxtjs/gtm to the modules section and provide your GTM ID in the below format:

modules: [
    ['@nuxtjs/gtm', { id: 'GTM-XXXXXXX' }]
]

To include the GTM script in your default layout file, you would use the $gtm instance that is attached to the context in asyncData, fetch, plugins, middleware and nuxtServerInit:

export default {
  async mounted() {
   if (this.$gtm) {
     this.$gtm.init('GTM-XXXXXXX')
   }
  }
}

Be sure to replace 'GTM-XXXXXXX' with your actual Google Tag Manager ID.

Setting up Custom Event Triggers and Data Layer Variables

With the setup above, you can now utilize the GTM to set up custom event triggers and data layer variables. To add a data layer variable in your Nuxt.js app, use the $gtm.push method like this:

this.$gtm.push({ event: 'myCustomEvent', someAdditionalData: 'some data'})

Now you have a custom event 'myCustomEvent' which you can trigger anytime in your application logic. The data layer variables can be used to provide additional context or information about the event.

Please note that GTM events and Google Analytics (GA) events are served different purposes. While GA events are generally used to measure user interactions and trends, GTM events can be more finely tuned to capture specifics of a user's behavior.

In sum, integrating Google Tag Manager with Nuxt.js projects brings a lot of flexibility for developers to manage tags and tracking without having to touch the codebase. It simplifies the implementation of Google Analytics and other tracking technologies. With this step-by-step tutorial, you now have the essential knowledge to set up GTM in a Nuxt.js application.

Incorporating Google Tag Manager into the Nuxt.js framework not only streamlines the process but also provides a number of unique benefits that developers might find useful.
