Third Party Libraries

@next/third-parties is a library that provides a collection of components and utilities that improve the performance and developer experience of loading popular third-party libraries in your Next.js application.

All third-party integrations provided by @next/third-parties have been optimized for performance and ease of use.

Getting Started

To get started, install the @next/third-parties library:

npm install @next/third-parties@latest next@latest

@next/third-parties is currently an experimental library under active development. We recommend installing it with the latest or canary flags while we work on adding more third-party integrations.

Google Third-Parties

All supported third-party libraries from Google can be imported from @next/third-parties/google.

Google Tag Manager

The GoogleTagManager component can be used to instantiate a Google Tag Manager container to your page. By default, it fetches the original inline script after hydration occurs on the page.

To load Google Tag Manager for all routes, include the component directly in your custom _app and pass in your GTM container ID:

import { GoogleTagManager } from "@next/third-parties/google";

export default function MyApp({ Component, pageProps }) {
  return (
    <>
      <Component {...pageProps} />
      <GoogleTagManager gtmId="GTM-XYZ" />
    </>
  );
}

To load Google Tag Manager for a single route, include the component in your page file:

import { GoogleTagManager } from "@next/third-parties/google";

export default function Page() {
  return <GoogleTagManager gtmId="GTM-XYZ" />;
}

Sending Events

The sendGTMEvent function can be used to track user interactions on your page by sending events using the dataLayer object. For this function to work, the <GoogleTagManager /> component must be included in either a parent layout, page, or component, or directly in the same file.

import { sendGTMEvent } from "@next/third-parties/google";

export function EventButton() {
  return (
    <div>
      <button
        onClick={() => sendGTMEvent("event", "buttonClicked", { value: "xyz" })}
      >
        Send Event
      </button>
    </div>
  );
}

Refer to the Tag Manager developer documentation to learn about the different variables and events that can be passed into the function.

Options

Options to pass to the Google Tag Manager. For a full list of options, read the Google Tag Manager docs.

Name	Type	Description
gtmId	Required	Your GTM container ID. Usually starts with GTM-.
dataLayer	Optional	Data layer object to instantiate the container with.
dataLayerName	Optional	Name of the data layer. Defaults to dataLayer.
auth	Optional	Value of authentication parameter (gtm_auth) for environment snippets.
preview	Optional	Value of preview parameter (gtm_preview) for environment snippets.

Google Analytics

The GoogleAnalytics component can be used to include Google Analytics 4 to your page via the Google tag (gtag.js). By default, it fetches the original scripts after hydration occurs on the page.

Recommendation: If Google Tag Manager is already included in your application, you can configure Google Analytics directly using it, rather than including Google Analytics as a separate component. Refer to the documentation to learn more about the differences between Tag Manager and gtag.js.

To load Google Analytics for all routes, include the component directly in your custom _app and pass in your measurement ID:

import { GoogleAnalytics } from "@next/third-parties/google";

export default function MyApp({ Component, pageProps }) {
  return (
    <>
      <Component {...pageProps} />
      <GoogleAnalytics gaId="G-XYZ" />
    </>
  );
}

To load Google Analytics for a single route, include the component in your page file:

import { GoogleAnalytics } from "@next/third-parties/google";

export default function Page() {
  return <GoogleAnalytics gaId="G-XYZ" />;
}

Sending Events

The sendGAEvent function can be used to measure user interactions on your page by sending events using the dataLayer object. For this function to work, the <GoogleAnalytics /> component must be included in either a parent layout, page, or component, or directly in the same file.

import { sendGAEvent } from "@next/third-parties/google";

export function EventButton() {
  return (
    <div>
      <button
        onClick={() => sendGAEvent("event", "buttonClicked", { value: "xyz" })}
      >
        Send Event
      </button>
    </div>
  );
}

Refer to the Google Analytics developer documentation to learn more about event parameters.

Tracking Pageviews

Google Analytics automatically tracks pageviews when the browser history state changes. This means that client-side navigations between Next.js routes will send pageview data without any configuration.

To ensure that client-side navigations are being measured correctly, verify that the “Enhanced Measurement” property is enabled in your Admin panel and the “Page changes based on browser history events” checkbox is selected.

Note: If you decide to manually send pageview events, make sure to disable the default pageview measurement to avoid having duplicate data. Refer to the Google Analytics developer documentation to learn more.

Options

Options to pass to the <GoogleAnalytics> component.

Name	Type	Description
gaId	Required	Your measurement ID. Usually starts with G-.
dataLayerName	Optional	Name of the data layer. Defaults to dataLayer.

Google Maps Embed

The GoogleMapsEmbed component can be used to add a Google Maps Embed to your page. By default, it uses the loading attribute to lazy-load the embed below the fold.

import { GoogleMapsEmbed } from "@next/third-parties/google";

export default function Page() {
  return (
    <GoogleMapsEmbed
      apiKey="XYZ"
      height={200}
      width="100%"
      mode="place"
      q="Brooklyn+Bridge,New+York,NY"
    />
  );
}

Options

Options to pass to the Google Maps Embed. For a full list of options, read the Google Map Embed docs.

Name	Type	Description
apiKey	Required	Your api key.
mode	Required	Map mode
height	Optional	Height of the embed. Defaults to auto.
width	Optional	Width of the embed. Defaults to auto.
style	Optional	Pass styles to the iframe.
allowfullscreen	Optional	Property to allow certain map parts to go full screen.
loading	Optional	Defaults to lazy. Consider changing if you know your embed will be above the fold.
q	Optional	Defines map marker location. This may be required depending on the map mode.
center	Optional	Defines the center of the map view.
zoom	Optional	Sets initial zoom level of the map.
maptype	Optional	Defines type of map tiles to load.
language	Optional	Defines the language to use for UI elements and for the display of labels on map tiles.
region	Optional	Defines the appropriate borders and labels to display, based on geo-political sensitivities.

YouTube Embed

The YouTubeEmbed component can be used to load and display a YouTube embed. This component loads faster by using lite-youtube-embed under the hood.

import { YouTubeEmbed } from "@next/third-parties/google";

export default function Page() {
  return (
    <YouTubeEmbed videoid="ogfYd705cRs" height={400} params="controls=0" />
  );
}

Options

Name	Type	Description
videoid	Required	YouTube video id.
width	Optional	Width of the video container. Defaults to auto
