How to use

Pay attention

Since v2.0 I'm using the context to share globally the config of the GTM for the Hook. If you're looking for the 1.x doc, check this

Basic

import { GTMProvider } from '@elgorditosalsero/react-gtm-hook'

const App = () => {
  const gtmParams = { id: 'GTM-ID' }

  return (
    <GTMProvider state={gtmParams}>
      <p>My awesome app</p>
    </GTMProvider>
  )
}

With custom DataLayer Name

import { GTMProvider } from '@elgorditosalsero/react-gtm-hook'

const App = () => {
  const gtmParams = {
    id: 'GTM-ID',
    dataLayerName: 'customDataLayerName'
  }

  return (
    <GTMProvider state={gtmParams}>
      <p>My awesome app</p>
    </GTMProvider>
  )
}

With custom DataLayer name and initial values

import { GTMProvider } from '@elgorditosalsero/react-gtm-hook'

const App = () => {
  const gtmParams = {
    id: 'GTM-ID',
    dataLayer: {
      'my-custom-value': 'value',
      'my-awesome-value': 'awesome'
    },
    dataLayerName: 'customDataLayerName'
  }

  return (
    <GTMProvider state={gtmParams}>
      <p>My awesome app</p>
    </GTMProvider>
  )
}

Use a GTM custom environment

import { GTMProvider } from '@elgorditosalsero/react-gtm-hook'

const App = () => {
  const gtmParams = {
    id: 'GTM-ID',
    environment: {
      gtm_auth: 'my-auth-token',
      gtm_preview: 'preview-id'
    }
  }

  return (
    <GTMProvider state={gtmParams}>
      <p>My awesome app</p>
    </GTMProvider>
  )
}

To find the gtm_auth and gtm_preview values for your custom GTM environment, go to Admin > Your Container > Environments > Your Environment > Actions > Get Snippet in your Google Tag Manager console. You will find the values you need embedded in the snippet.

Sending data to GTM

import { GTMProvider, useGTMDispatch } from '@elgorditosalsero/react-gtm-hook'

const App = () => {
  const gtmParams = {
    id: 'GTM-ID',
    dataLayerName: 'customDataLayerName'
  }

  return (
    <GTMProvider state={gtmParams}>
      <div>
        <p>My awesome app</p>
        <MyAwesomeComp />
      </div>
    </GTMProvider>
  )
}

const MyAwesomeComp = () => {
  const sendDataToGTM = useGTMDispatch()

  const handleClick = () => sendDataToGTM({ event: 'awesomeButtonClicked', value: 'imAwesome' })

  return (
    <div>
      <p>My Awesome Comp</p>
      <button onClick={handleClick}>My Awesome Button</button>
    </div>
  )
}
