• Test covered

🛠 Install

npm install gtm-react-hook
or
yarn add gtm-react-hook

🚀 Quickstart

import React, { useEffect } from "react";
import { useGTM } from "gtm-react-hook";
import { useLocation } from "react-router-dom";

const App = () => {
  const { runGTM, eventGTM } = useGTM();
  const location = useLocation();

  useEffect(() => {
    runGTM({
      tagId: "GTM-XXXXXXX", // Provide your Tag ID
    });
  }, []);

  useEffect(() => {
    eventGTM("page_view", {
      pathname: location.pathname,
    });
  }, [location.pathname]);

  return <>...</>;
};

🧙🏻‍♂️ API

useGTM()

const { runGTM, eventGTM } = useGTM();

runGTM({ tagId: string, dataLayerName?: object, environment?: { gtm_auth: string, gtm_preview: string }, domain?: string, script?: string, nonce?: string, devMode?: boolean })

1. tagId (required) - your GTM measurement ID;
2. dataLayerName - custom name of dataLayer object;
3. environment - GTM environment params;
4. domain - custom GTM domain;
5. script - custom GTM script's name;
6. nonce;
7. devMode - add logging for GTM initialization & events;

eventGTM(eventName: string, data?: object)

1. eventName (required) - name of an event;
2. data - payload of dataLayer (action, url, customerID, etc);

💅🏽 Examples

Page tracking

const { eventGTM } = useGTM();
const location = useLocation();

useEffect(() => {
  eventGTM("page_view", { location: location.pathname });
}, [location]);

Track event

const { eventGTM } = useGTM();

const handleSaveCustomerInfo = (customer) => {
  eventGTM("customer_info", {
    customerId: customer.customerId,
    customerRegion: customer.customerRegion,
  });
};

return <button onClick={handleSaveCustomerInfo}>Submit</button>;

Custom data layer name

const { runGTM } = useGTM();

useEffect(() => {
  runGTM({
    gtmId: "GTM-XXXXXXX",
    dataLayerName: "myGTMLayer", // all GTM events will be stored in `window.myGTMLayer` key
  });
}, []);

Installation only after user has accepted analytics

const { runGTM } = useGTM();

useEffect(() => {
  if (isUserConfirmAnalytics) {
    runGTM({
      gtmId: "GTM-XXXXXXX",
    });
  }
}, [isUserConfirmAnalytics]);

Logging

const { runGTM } = useGTM();

useEffect(() => {
  runGTM({
    gtmId: "GTM-XXXXXXX",
    devMode: true, // add GTM logs to browser's console
  });
}, []);
