nav_title: Third Party Libraries
description: Optimize the performance of third-party libraries in your application with the `@next/third-parties` package.

{/* The content of this doc is shared between the app and pages router. You can use the `Content` component to add content that is specific to the Pages Router. Any shared content should not be wrapped in a component. */}
**`@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:
```bash filename="Terminal"
npm install @next/third-parties@latest next@latest
```
{/* To do: Remove this paragraph once package becomes stable */}
`@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](https://developers.google.com/tag-platform/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 root layout and pass in your GTM container ID:
```tsx filename="app/layout.tsx" switcher
import { GoogleTagManager } from '@next/third-parties/google'
export default function RootLayout({
children,
}: {
children: React.ReactNode
}) {
return (
{children}
)
}
```
```jsx filename="app/layout.js" switcher
import { GoogleTagManager } from '@next/third-parties/google'
export default function RootLayout({ children }) {
return (
{children}
)
}
```
To load Google Tag Manager for all routes, include the component directly in your custom `_app` and
pass in your GTM container ID:
```jsx filename="pages/_app.js"
import { GoogleTagManager } from '@next/third-parties/google'
export default function MyApp({ Component, pageProps }) {
return (
<>
)
}
```
To load Google Tag Manager for a single route, include the component in your page file:
```jsx filename="app/page.js"
import { GoogleTagManager } from '@next/third-parties/google'
export default function Page() {
return
}
```
```jsx filename="pages/index.js"
import { GoogleTagManager } from '@next/third-parties/google'
export default function Page() {
return
}
```
#### 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 `` component must be
included in either a parent layout, page, or component, or directly in the same file.
```jsx filename="app/page.js"
'use client'
import { sendGTMEvent } from '@next/third-parties/google'
export function EventButton() {
return (
)
}
```
```jsx filename="pages/index.js"
import { sendGTMEvent } from '@next/third-parties/google'
export function EventButton() {
return (
)
}
```
Refer to the Tag Manager [developer
documentation](https://developers.google.com/tag-platform/tag-manager/datalayer) to learn about the
different variables and events that can be passed into the function.
#### Server-side Tagging
If you're using a server-side tag manager and serving `gtm.js` scripts from your tagging server you can
use `gtmScriptUrl` option to specify the URL of the script.
#### Options
Options to pass to the Google Tag Manager. For a full list of options, read the [Google Tag Manager
docs](https://developers.google.com/tag-platform/tag-manager/datalayer).
| Name | Type | Description |
| --------------- | -------- | ------------------------------------------------------------------------ |
| `gtmId` | Required | Your GTM container ID. Usually starts with `GTM-`. |
| `gtmScriptUrl` | Optional | GTM script URL. Defaults to `https://www.googletagmanager.com/gtm.js`. |
| `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](https://developers.google.com/analytics/devguides/collection/ga4) 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](https://developers.google.com/analytics/devguides/collection/ga4/tag-options#what-is-gtm)
> 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 root layout and pass
in your measurement ID:
```tsx filename="app/layout.tsx" switcher
import { GoogleAnalytics } from '@next/third-parties/google'
export default function RootLayout({
children,
}: {
children: React.ReactNode
}) {
return (
{children}
)
}
```
```jsx filename="app/layout.js" switcher
import { GoogleAnalytics } from '@next/third-parties/google'
export default function RootLayout({ children }) {
return (
{children}
)
}
```
To load Google Analytics for all routes, include the component directly in your custom `_app` and
pass in your measurement ID:
```jsx filename="pages/_app.js"
import { GoogleAnalytics } from '@next/third-parties/google'
export default function MyApp({ Component, pageProps }) {
return (
<>
)
}
```
To load Google Analytics for a single route, include the component in your page file:
```jsx filename="app/page.js"
import { GoogleAnalytics } from '@next/third-parties/google'
export default function Page() {
return
}
```
```jsx filename="pages/index.js"
import { GoogleAnalytics } from '@next/third-parties/google'
export default function Page() {
return
}
```
#### 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 `` component must be
included in either a parent layout, page, or component, or directly in the same file.
```jsx filename="app/page.js"
'use client'
import { sendGAEvent } from '@next/third-parties/google'
export function EventButton() {
return (
)
}
```
```jsx filename="pages/index.js"
import { sendGAEvent } from '@next/third-parties/google'
export function EventButton() {
return (
)
}
```
Refer to the Google Analytics [developer
documentation](https://developers.google.com/analytics/devguides/collection/ga4/event-parameters) 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”_](https://support.google.com/analytics/answer/9216061#enable_disable) 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](https://developers.google.com/analytics/devguides/collection/ga4/views?client_type=gtag#manual_pageviews)
> to learn more.
#### Options
Options to pass to the `` component.
| Name | Type | Description |
| --------------- | -------- | ------------------------------------------------------------------------------------------------------ |
| `gaId` | Required | Your [measurement ID](https://support.google.com/analytics/answer/12270356). Usually starts with `G-`. |
| `dataLayerName` | Optional | Name of the data layer. Defaults to `dataLayer`. |
| `nonce` | Optional | A [nonce](/docs/app/guides/content-security-policy#nonces). |
### Google Maps Embed
The `GoogleMapsEmbed` component can be used to add a [Google Maps
Embed](https://developers.google.com/maps/documentation/embed/embedding-map) to your page. By
default, it uses the `loading` attribute to lazy-load the embed below the fold.
```jsx filename="app/page.js"
import { GoogleMapsEmbed } from '@next/third-parties/google'
export default function Page() {
return (
)
}
```
```jsx filename="pages/index.js"
import { GoogleMapsEmbed } from '@next/third-parties/google'
export default function Page() {
return (
)
}
```
#### Options
Options to pass to the Google Maps Embed. For a full list of options, read the [Google Map Embed
docs](https://developers.google.com/maps/documentation/embed/embedding-map).
| Name | Type | Description |

| `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`](https://github.com/paulirish/lite-youtube-embed) under the
hood.
```jsx filename="app/page.js"
import { YouTubeEmbed } from '@next/third-parties/google'
export default function Page() {
