This guide will help you integrate RudderStack with your Nuxt.js app using the RudderStack JavaScript SDK. On successful integration, you can track and send real-time user events to your preferred destinations via RudderStack.

To set up the event stream on your Nuxt.js app, you need to perform the following steps:

1. Integrate the JavaScript SDK with your Nuxt.js app and set up the tracking code
2. Configure a destination in RudderStack
3. Deploy your Nuxt.js app and verify the events

Prerequisites

This guide assumes you have installed and set up your Nuxt.js app. You can refer to the official Nuxt.js documentation for more information.

Integrating the JavaScript SDK with your Nuxt.js app

Integrating the JavaScript SDK with your Nuxt.js app involves the following steps:

1. Creating a JavaScript source in RudderStack
2. Installing and configuring the JavaScript SDK in your Nuxt.js app

Creating a JavaScript source

The RudderStack JavaScript source is required track the events from your Nuxt.js app. Follow these steps to set it up in your RudderStack dashboard:

1. Note the data plane URL in your RudderStack dashboard. This is required to set up the JavaScript SDK in your Nuxt.js app.

2. Click the Sources button in the left navigation bar and select New Source to create a source. Then, select Event Streams under Sources, and select JavaScript.

3. Assign a name to your source and click Next.
4. Your JavaScript source is now configured. Note down the write key for this source, as shown:

Installing and configuring the JavaScript SDK in your Nuxt.js app

To integrate RudderStack with your Nuxt.js app and set up the tracking code, follow the steps below:

1. In your app's folder, open nuxt.config.js and include the following snippet within the head: section:

Copy
script: [{
    hid: 'Rudder-JS',
    src: 'http://cdn.rudderlabs.com/v1.1/rudder-analytics.min.js',
    defer: true
  },
  {
    hid: 'rudder-js',
    innerHTML: `
        rudderanalytics = window.rudderanalytics = [];
        var  methods = [
            'load',
            'page',
            'track',
            'identify',
            'alias',
            'group',
            'ready',
            'reset',
            'getAnonymousId',
            'setAnonymousId'
        ];
        for (var i = 0; i < methods.length; i++) {
              var method = methods[i];
              rudderanalytics[method] = function (methodName) {
                    return function () {
                                       rudderanalytics.push([methodName].concat(Array.prototype.slice.call(arguments)));
                    };
                  }(method);
        }
        rudderanalytics.load("WRITE_KEY", "DATA_PLANE_URL");
        rudderanalytics.ready(()=>{
          console.log("We are all set");
        });
        //rudderanalytics.page();
        `,
    type: 'text/javascript',
    charset: 'utf-8'
  }
],

2. Replace <WRITE_KEY> and <DATA_PLANE_URL> with your JavaScript source write key and the data plane URL obtained in the Creating a JavaScript source in RudderStack section above.

Configuring a destination tool in RudderStack

This section details the steps required to set up a destination platform in RudderStack where you can send all the events tracked by the JavaScript SDK.

1. Click Add Destination in RudderStack dashboard's home page.
2. Choose Google Analytics from the list of destinations.
3. Assign a name to your destination and click Next.
4. Select the JavaScript source configured in the above section and click Next.
5. Configure your Google Analytics destination with your Google Analytics Tracking ID in the Connection Settings page. For details on the other settings, refer to the Google Analytics documentation.

Google Analytics is now configured as a destination. You should be able to see the connection in your RudderStack dashboard, as seen below:

Deploying your Nuxt.js app and verifying the event stream

To verify if your event stream is working correctly, deploy your Nuxt.js app and test if the events are tracked and delivered correctly. Follow these steps:

1. Deploy your Nuxt.js app by running the following command:

Copy
npm run dev

2. Open the local server URL(generally http://localhost:3000/) in your browser to view the app.
3. To verify if the RudderStack JavaScript SDK(rudder-analytics.js) is loaded correctly, go to your browser's developer tools and check the Network tab. The following image highlights this option for the Google Chrome browser:

4. Click the various links or pages in your app for RudderStack to track these actions.
5. To check if the events are tracked, go to the Live Events tab of your JavaScript source in the RudderStack dashboard:

6. Upon successful tracking, you will see the events in your RudderStack dashboard:

7. In your Google Analytics dashboard, go to Realtime > Events to check if the events are delivered. Your tracked events will be shown in this window along with other metrics such as number of active users, source platform, etc.
