A lightweight React library to implement custom Google Tag Manager events.
Designed to use and extend Google Analytics 4. Note: If upgrading from react-gtm 0.0.6 or older, or currently using an older version of Google Analytics, you'll need to upgrade. This library is also SSR safe and does not break when used without window existing. This package is intended to be used with React / older Next.JS apps, for Next.JS 11 and above we recommend using @phntms/next-gtm.
Install this package with npm.
npm i @phntms/react-gtm| Property | Type | Default | Notes |
|---|---|---|---|
| id | string |
undefined | ID that uniquely identifies GTM Container. Example format: GTM-xxxxxx. |
| disable | boolean |
false | Used to disable tracking events. Use if you want user to consent to being tracked before tracking events. |
To initialize GTM, add TrackingHeadScript to the head of the page.
Example initialization in Next.js:
import Document, {
Html,
Head,
Main,
NextScript,
} from "next/document";
import { TrackingHeadScript } from "@phntms/react-gtm";
const GA_TRACKING_ID = process.env.NEXT_PUBLIC_GA_TRACKING_ID || "";
export default class MyDocument extends Document {
render = () => (
<Html>
<Head>
<TrackingHeadScript id={GA_TRACKING_ID} />
</Head>
<body>
<Main />
<NextScript />
</body>
</Html>
);
}Note: If used alongside any cookie consent scripts, <TrackingHeadScript /> must be placed after.

Example of a basic tracking event:

trackEvent({

data: {
action: "Click - To: https://phantom.land/",
category: "CTA",
label: "Click",
},
});| Parameter | Type | Default | Notes |
|---|---|---|---|
| id | string |
undefined | Same ID used in TrackingHeadScript. Example format: GTM-xxxxxx. |
| enable | boolean |
true | Used to enable or disable tracking events. |
Note: This should only be used if needed, for example after user has consented to being tracked. You shouldn't need to toggle this in normal usage.

|---|---|---|---|---|
| event | string |
"customEvent" | No | Custom GTM event name, defaults to customEvent. |
| data | EventDataProps |

This library extends window and exposes the window.dataLayer GTM container object.
