Getting Started with FullStory React Native Capture

Overview

The FullStory React Native Plugin works in conjunction with and does not replace the FullStory for Mobile Apps Plugin.

As you're implementing the instructions below, you may find it useful to reference a sample app with FullStory integrated. We have an example of the SDK being implemented into a React Native app here.

Configure FullStory for Mobile Apps

First, make sure your Android and iOS projects are properly configured with FullStory for Mobile Apps.

This step can be skipped in an Expo Managed Workflow.

Adding the FullStory React Native Plugin

Modify your application’s package.json file and add the FullStory React Native Plugin as a dependency:

"dependencies": {
   ...
    "@fullstory/react-native": "^1.2.0"
  },

Once this is done, execute yarn install or npm install to bring in the new dependencies.

• iOS
  • Legacy Projects: If your React Native project does not auto-link dependencies, add the following to ios/Podfile:

pod 'fullstory_react-native', :path => '../node_modules/@fullstory/react-native'

All Projects: In the ios sub-directory, execute pod update or pod install

Configuring the React Native Plugin

The FullStory React Native Plugin includes 2 babel dependencies.

@fullstory/react-native must be configured while @fullstory/babel-plugin-annotate-react is optional.

Modify your application’s babel.config.js file and add the plugins:

module.exports = {
  /* ... */
  plugins: [
    /* ... */
    "@fullstory/react-native",
    [ "@fullstory/babel-plugin-annotate-react", {
      native: true,
      setFSTagName: true
    }]
  ]
};

Configuring for Expo

FullStory React Native currently does not support Expo Go workflows. For Expo Go users, we suggest transitioning to development builds to get the Expo client experience with the ability customize native code.

Add the config plugin to the plugins array of your app.json  or app.config.json

{
 "expo": {
   "plugins": [
     [
       "@fullstory/react-native",
       {
         "version": "<THE PLUGIN VERSION>",
         "org": "<YOUR ORG ID HERE>"
       }
     ]
   ]
 }
}

Note: <THE PLUGIN VERSION>refers to the FullStory for Mobile Apps plugin version. See the Release Notes to find the latest version.

Plugin Properties

Plugins allow for extra customization by passing in an object with properties. If no extra properties are added, defaults will be used. Certain properties are required.

Troubleshooting

Run expo prebuild to generate native files without running your app.

Verify that the correct native file changes have been applied in your /ios and /android folders by comparing the changes with the iOS and Android documentation.

If incorrect native file changes have been applied, please contact support so that we can further troubleshoot.

Limitations

Metro Server Support

The FullStory React Native Plugin uses babel plugins to perform transformations on JSX to enable privacy state declarations and to capture click events. During development, it is possible for Metro’s caching and hot module reloading to corrupt these transformations and cause unexpected bugs in FullStory sessions.

Therefore, we recommend disabling FullStory while running a local Metro Server during development.

Automatic props provided to React Native components

The included babel plugins, when properly configured, will provide read-only and writable props.

• Read-only props to help with element identity:
  data-component
data-element
data-source-file
  
  
• Writable props:
  fsAttribute
fsClass
fsTagName

Limitations: The automatic props are not respected on layout-only components at this time. Additionally for custom components, you can also inherit support as below:

const MyCustomComponent = (props) => {
  return (
    <View fsClass={this.props.fsClass}>
      <Text >Text goes here</Text>
    </View>
  );
}

Note: In order to use our automatic properties with Typescript, you can create a tsx file with the following contents:

declare global {
  namespace JSX {
    interface IntrinsicAttributes {
      fsAttribute?: {[key: string]: string};
      fsClass?: string;
      fsTagName?: string;
    }
  }
}

export {};

Using fsAttribute for Privacy Rules

• You can utilize the new fsAttribute prop to help create selector-based rules in the FullStory app settings.

<Text fsAttribute={{attr1: 'custom_value1', attr2: 'custom_value2'}}>Text element with custom attributes</Text>

• The corresponding selector in the FullStory app settings:

Using fsTagName for Privacy Rules

• You can utilize the new fsTagName prop to help create selector-based rules in the FullStory app settings. 

  <text fsTagName="my_tag_name">Text element with custom tagName</Text>

  The corresponding selector in the FullStory app settings:

Using fsClass for Privacy Rules

You can use the new fsClass prop on React Native elements to declare privacy rules.

• Standard privacy rules

<Text fsClass="fs-exclude">Text element that is excluded</Text>
<Text fsClass="fs-mask">Text element that is masked</Text>
<Text fsClass="fs-unmask">Text element that is unmasked</Text>

• Consent privacy rules

<Text fsClass="fs-exclude-without-consent">Text element that is excluded unless the user consents</Text>
<Text fsClass="fs-mask-without-consent">Text element that is masked unless the user consents</Text>
<Text fsClass="fs-unmask-with-consent">Text element that is unmasked only if the user consents</Text>

Using testID for Privacy Rules

You can also utilize React Native’s built-in testID prop to help create selector-based rules in the FullStory app settings.

<Text testID="test_id_for_unmasking">Text element that is unmasked via privacy rules settings</Text>

• The corresponding selector in the FullStory app settings:

FullStory API

Supported API methods

• Support for the FullStory JS API has been added with the following methods:
  anonymize
consent
event
getCurrentSession
getCurrentSessionURL
identify
onReady
restart
shutdown
setUserVars
FullStory.shutdown

Using the FS API

• Import the FullStory API via:
  

import FullStory from '@fullstory/react-native';

In your React Native app, once you import the FullStory plugin, you can call any of the supported API methods.

• Using FullStory.anonymize
Anonymize can be invoked via:

FullStory.anonymize();

• Using FullStory.consent 
  Consent can be granted via:

FullStory.consent(true);

• Using FullStory.event 
  A custom event can be invoked via:

FullStory.event('Checkout invoked', {
  page_str: 'Checkout Page',
  cart_amount_real: 299,
});

Note: array values are not currently supported. 

• Using FullStory.getCurrentSession 
  We can retrieve the current session ID:
  

  FullStory.getCurrentSession().then(function(result) {
    const sessionId = result;
  });

  Note: this will be null if called before a session is active.
  
  

• Using FullStory.getCurrentSessionURL 
  We can retrieve the current session URL:
  

  FullStory.getCurrentSessionURL().then(function(result) {
    const sessionUrl = result;
  });

  Note: this will be null if called before a session is active.
  
  

• Using FullStory.identify 
  User identify is set via:
  

  FullStory.identify('462718483', {
   displayName: 'Daniel Falko',
   Email: 'daniel.falko@example.com',
  });

  Note: array values are not currently supported.
  
  

• Using FullStory.onReady
  We can subscribe to a callback to be invoked when we have a session:
  

  FullStory.onReady().then(function(result) {
    const replayStartUrl = result.replayStartUrl;
    const replayNowUrl = result.replayNowUrl;
    const sessionId = result.sessionId;
  });

• Using FullStory.restart
  We can invoke a request for a new session:

FullStory.restart();

• UsingFullStory.setUserVars
  User vars can be set via:

FullStory.setUserVars({
"displayName" : "Daniel Falko",
"email" : "daniel.falko@example.com",
"pricingPlan_str" : "free", // is he a freemium, basic, or pro customer?
"popupHelp_bool" : true, // did he turn off the aggressive in-app help?
"totalSpent_real" : 14.50 // how much has he spent on in-app purchases so far?
});

Note: array values are not currently supported.

• Using FullStory.shutdown
  We can shutdown the current session:

  FullStory.shutdown();

New in FullStory React Native Plugin 1.0.3

• Using FullStory.log
  Logging can be used via:
  

  FullStory.log(FullStory.LogLevel.Log, 'Log at Log'); // on iOS, clamps to Debug

  FullStory.log(FullStory.LogLevel.Debug, 'Log at Debug');

  FullStory.log(FullStory.LogLevel.Info, 'Log at Info');

  FullStory.log(FullStory.LogLevel.Warn, 'Log at Warn');

  FullStory.log(FullStory.LogLevel.Error, 'Log at Error');

  FullStory.log(FullStory.LogLevel.Assert, 'Log at Assert'); // on Android, clamps to Error

  Note: If an invalid level is specified, it will default to Info.
