Capacitor Firebase Analytics Plugin

Unofficial Capacitor plugin for Firebase Analytics.[^1]

Use Cases

The Firebase Analytics plugin is typically used to understand how users interact with your app, for example:

• Event tracking: Log app events such as sign-ups with custom parameters using logEvent(...).
• Screen tracking: Record which screens users visit using setCurrentScreen(...).
• Audience segmentation: Assign user IDs and custom user properties to segment your users.
• Consent management: Set the user's consent mode and enable or disable data collection to comply with privacy requirements.
• Conversion measurement: Initiate on-device conversion measurement with an email address or phone number on iOS.

Installation

You can use our AI-Assisted Setup to install the plugin. Add the Capawesome Skills to your AI tool using the following command:

npx skills add capawesome-team/skills --skill capacitor-plugins

Then use the following prompt:

Use the `capacitor-plugins` skill from `capawesome-team/skills` to install the `@capacitor-firebase/analytics` plugin in my project.

If you prefer Manual Setup, install the plugin by running the following commands and follow the platform-specific instructions below:

npm install @capacitor-firebase/analytics firebase
npx cap sync

Add Firebase to your project if you haven't already (Android / iOS / Web).

Android

Disable Analytics data collection

See Disable Analytics data collection if you want to disable Analytics data collection.

Disable Advertising ID collection

See Disable Advertising ID collection if you want to disable Advertising ID collection.

Variables

If needed, you can define the following project variable in your app’s variables.gradle file to change the default version of the dependency:

• $firebaseAnalyticsVersion version of com.google.firebase:firebase-analytics (default: 23.0.0)

This can be useful if you encounter dependency conflicts with other plugins in your project.

iOS

Swift Package Manager

Add the following to your capacitor.config.json (or capacitor.config.ts) to avoid a SwiftPM package identity collision:

{
  "experimental": {
    "ios": {
      "spm": {
        "packageOptions": {
          "@capacitor-firebase/analytics": {
            "symlink": true
          }
        }
      }
    }
  }
}

Attention: SPM packageOptions support requires Capacitor CLI 8.4.0+.

If you are using CocoaPods for your iOS project, you need to add the CapacitorFirebaseAnalytics/Analytics pod to your Podfile (usually ios/App/Podfile):

target 'App' do
capacitor_pods
# Add your Pods here
+  pod 'CapacitorFirebaseAnalytics/Analytics', :path => '../../node_modules/@capacitor-firebase/analytics'
end

Attention: Do not add the pod in the section def capacitor_pods, but under the comment # Add your Pods here (example).

Disable Analytics data collection

See Disable Analytics data collection if you want to disable Analytics data collection.

Disable IDFA collection

If you are using CocoaPods for your iOS project and you want to disable IDFA collection, you can use the CapacitorFirebaseAnalytics/AnalyticsWithoutAdIdSupport pod instead of the CapacitorFirebaseAnalytics/Analytics pod:

target 'App' do
capacitor_pods
# Add your Pods here
-  pod 'CapacitorFirebaseAnalytics/Analytics', :path => '../../node_modules/@capacitor-firebase/analytics'
+  pod 'CapacitorFirebaseAnalytics/AnalyticsWithoutAdIdSupport', :path => '../../node_modules/@capacitor-firebase/analytics'
end

If you are using Swift Package Manager for your iOS project and you want to disable IDFA collection, you can enable the AnalyticsWithoutAdIdSupport trait in your capacitor.config.json (or capacitor.config.ts):

{
  "experimental": {
    "ios": {
      "spm": {
        "swiftToolsVersion": "6.1",
        "packageTraits": {
          "@capacitor-firebase/analytics": ["AnalyticsWithoutAdIdSupport"]
        }
      }
    }
  }
}

Note: SPM trait support requires Capacitor CLI 8.3.0+ and Xcode 16.3+ (Swift 6.1+).

Configuration

No configuration required for this plugin.

Demo

A working example can be found here: robingenz/capacitor-firebase-plugin-demo

Usage

The following examples show how to log events, track screens, identify users, manage data collection, configure the session timeout, and initiate on-device conversion measurement.

Log events

Log an app event with a name and optional parameters:

import { FirebaseAnalytics } from '@capacitor-firebase/analytics';

const logEvent = async () => {
  await FirebaseAnalytics.logEvent({
    name: 'sign_up',
    params: { method: 'password' },
  });
};

Track screens

Set the current screen name to record which screens users visit. The screenClassOverride option is only available on Android and iOS:

import { FirebaseAnalytics } from '@capacitor-firebase/analytics';

const setCurrentScreen = async () => {
  await FirebaseAnalytics.setCurrentScreen({
    screenName: 'Login',
    screenClassOverride: 'LoginPage',
  });
};

Identify users

Set the user ID property and custom user properties to segment your users:

import { FirebaseAnalytics } from '@capacitor-firebase/analytics';

const setUserId = async () => {
  await FirebaseAnalytics.setUserId({
    userId: '123',
  });
};

const setUserProperty = async () => {
  await FirebaseAnalytics.setUserProperty({
    key: 'language',
    value: 'en',
  });
};

Manage data collection

Enable or disable automatic data collection (the value does not apply until the next run of the app), check whether it is enabled (only available on Web), or clear all analytics data from the device (only available on Android and iOS):

import { FirebaseAnalytics } from '@capacitor-firebase/analytics';

const setEnabled = async () => {
  await FirebaseAnalytics.setEnabled({
    enabled: true,
  });
};

const isEnabled = async () => {
  const { enabled } = await FirebaseAnalytics.isEnabled();
  return enabled;
};

const resetAnalyticsData = async () => {
  await FirebaseAnalytics.resetAnalyticsData();
};

Configure the session timeout

Set the duration of inactivity that terminates the current session. Only available on Android and iOS:

import { FirebaseAnalytics } from '@capacitor-firebase/analytics';

const setSessionTimeoutDuration = async () => {
  await FirebaseAnalytics.setSessionTimeoutDuration({
    duration: '120',
  });
};

Initiate on-device conversion measurement

Initiate on-device conversion measurement with a plain or hashed email address or phone number. Only available on iOS:

import { FirebaseAnalytics } from '@capacitor-firebase/analytics';

const initiateOnDeviceConversionMeasurementWithEmailAddress = async () => {
  await FirebaseAnalytics.initiateOnDeviceConversionMeasurementWithEmailAddress({
    emailAddress: '[email protected]',
  });
};

const initiateOnDeviceConversionMeasurementWithPhoneNumber = async () => {
  await FirebaseAnalytics.initiateOnDeviceConversionMeasurementWithPhoneNumber({
    phoneNumber: '+49123456789',
  });
};

const initiateOnDeviceConversionMeasurementWithHashedEmailAddress = async () => {
  await FirebaseAnalytics.initiateOnDeviceConversionMeasurementWithHashedEmailAddress({
    emailAddressToHash: '[email protected]',
  });
};

const initiateOnDeviceConversionMeasurementWithHashedPhoneNumber = async () => {
  await FirebaseAnalytics.initiateOnDeviceConversionMeasurementWithHashedPhoneNumber({
    phoneNumberToHash: '+49123456789',
  });
};

Test your implementation

Here you can find more information on how to test the Firebase Analytics implementation using the DebugView.

FAQ

How can I verify that my events are being logged?

Use the DebugView in the Firebase console to inspect events as they are logged by your app. See the DebugView documentation for more information on how to test your Firebase Analytics implementation.

How can I disable analytics data collection?

You can enable or disable automatic data collection at runtime using the setEnabled(...) method; note that the value does not apply until the next run of the app. To disable data collection by default, follow the platform-specific instructions linked in the Installation section for Android and iOS.

How do I set the user's consent mode?

Call the setConsent(...) method with a consent type (for example analytics storage or ad storage) and a consent status (granted or denied). This allows you to manage what data is collected based on the user's consent.

Why is the app instance ID not defined?

The appInstanceId returned by getAppInstanceId() is not defined if the analytics storage consent type has been set to denied via setConsent(...). Also note that getAppInstanceId() is only available on Android and iOS.

How do I disable Advertising ID or IDFA collection?

On Android, follow the Disable Advertising ID collection guide. On iOS, use the CapacitorFirebaseAnalytics/AnalyticsWithoutAdIdSupport pod instead of the CapacitorFirebaseAnalytics/Analytics pod if you are using CocoaPods, or enable the AnalyticsWithoutAdIdSupport package trait if you are using Swift Package Manager. See the Installation section for details.

Can I use this plugin with Ionic, React, Vue or Angular?

Yes, the plugin is framework-agnostic. It works in any Capacitor app regardless of the web framework, including Ionic with Angular, React, or Vue, as well as plain JavaScript projects.
