npm install @analytics/google-analyticsHow to use
The @analytics/google-analytics package works in the browser. To use, install the package, include in your project and initialize the plugin with analytics.
Below is an example of how to use the browser plugin.
import Analytics from 'analytics'
import googleAnalytics from '@analytics/google-analytics'
const analytics = Analytics({
app: 'awesome-app',
plugins: [
googleAnalytics({
measurementIds: ['G-abc123']
})
]
})
/* Track a page view */
analytics.page()
/* Track a custom event */
analytics.track('cartCheckout', {
item: 'pink socks',
price: 20
})
/* Identify a visitor */
analytics.identify('user-id-xyz', {
firstName: 'bill',
lastName: 'murray'
})After initializing analytics with the googleAnalytics plugin, data will be sent into Google Analytics whenever analytics.identify, analytics.page, or analytics.track are called.
See additional implementation examples for more details on using in your project.

</html>Fix "double page views"
Google analytics 4 sometimes automatically sends a page view for single page applications. To disable this you will need to go into the settings of your stream and click into "enhanced measurement" section and uncheck the "Page changes based on browser history events" setting. This will make sure only analytics.page() calls will send page views to Google analytics v4.
Legacy Google analytics v3
For the older version of google analytics please see the @analytics/google-analytics-v3 package or the GA3 plugin docs
Using GA3 and GA4 together
It is possible to use both GA3 and GA4 together shown below. Just remember GA3 will be deprecated starting in July of 2023
import Analytics from 'analytics'
import googleAnalyticsPlugin from '@analytics/google-analytics'
import googleAnalyticsV3Plugin from '@analytics/google-analytics-v3'
/* Initialize analytics instance */
const analytics = Analytics({
app: 'my-app',
plugins: [
/* Load Google Analytics v4 */
googleAnalyticsPlugin({
measurementIds: ['G-abc123'],
}),
/* Load Google Analytics v3 */
googleAnalyticsV3Plugin({
trackingId: 'UA-11111111-2',
}),
],
})
analytics.page()
