# React Native: GoogleTagManager

* [Setup](/redux-beacon/index/react-native-google-tag-manager.md#setup)
* [Usage](/redux-beacon/index/react-native-google-tag-manager.md#usage)
* [Event Definitions](/redux-beacon/index/react-native-google-tag-manager.md#event-definitions)

## Setup

1. Sign up for Google Tag Manager and [create a mobile container](https://support.google.com/tagmanager/answer/6103696?hl=en#MobileContainers). Select **Legacy** for SDK Version, and be sure to make a note of your property's [tracking Id](https://support.google.com/analytics/answer/1008080).
2. Install the following npm package, [GoogleAnalyticsBridge](https://www.npmjs.com/package/react-native-google-analytics-bridge).
3. For each mobile platform (Android or iOS), you need to follow its corresponding [manual installation](https://github.com/idehub/react-native-google-analytics-bridge/wiki/Manual-installation) for GoogleAnalyticsBridge usage.
4. Install the target:

   ```bash
   npm install --save @redux-beacon/react-native-google-tag-manager
   ```

## Usage

```javascript
   import { Platform } from 'react-native';
   import { GoogleTagManager as GTMBridge } from 'react-native-google-analytics-bridge';
   import GoogleTagManager from '@redux-beacon/react-native-google-tag-manager';

   // Create or import an events map.
   // See "getting started" pages for instructions.

   const containerId = (Platform.OS === 'ios') ? 'GTM-IOSXXXX' : 'GTM-ANDROID';

   const gtm = GoogleTagManager(containerId, GTMBridge);
   const gtmMiddleware = createMiddleware(eventsMap, gtm);
```

## Event Definitions

```javascript
const event = (action, prevState, nextState) => {
  return {
    event: /* fill me in */,
    /* add any additional key/value pairs below */,
  };
};
```

### Notes

* If an event object doesn't have an `event` property, but has a `hitType` property, this target will create an `event` property and set it to the `hitType` string. For example:

  ```javascript
  // Given the following event definition
  const pageview = action => ({
    hitType: 'pageview',
    page: action.payload,
  });

  // Say the action is equal to
  // { type: LOCATION_CHANGE, payload: '/home' }
  // The following object will get pushed to the dataLayer
  const dataLayerEvent = {
    hitType: 'pageview',
    event: 'pageview', // this is done automatically
    page: '/home',
  };
  ```

{% hint style="info" %}
This gives you the option to use the event definitions exposed by the [Google Analytics target](broken://pages/-L8oOdRl7fxTyScYqz7w#event-definitions)
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://rangle.gitbook.io/redux-beacon/index/react-native-google-tag-manager.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
