React Native Firebase (v6) 🔥

In this version we have separate packages for every different module unlike versions < 6.0.

Installation

Install the firebase app module which is the base requirement for adding any further firebase modules.

npm install --save @react-native-firebase/app

Download the google-services.json file and place it in the following location of your project /android/app/google-services.json.

For android add google-services plugin as a dependency inside of the /android/build.gradle file:

buildscript {
  dependencies {
    // ... other dependencies
    classpath 'com.google.gms:google-services:4.2.0'
  }
}

Add the following plugin to the very bottom of the /android/app/build.gradle file:

apply plugin: 'com.google.gms.google-services'

Push Notifications

Note: Push notifications in foreground are not supported in version 6. You will get a callback in onMessage function and you can display an alert on it.

You can use following libraries for push notification:

• react-native-notifee https://github.com/notifee/react-native-notifee (Paid)
• react-native-notification https://github.com/wix/react-native-notifications (Free)
• react-native-push-notification https://github.com/zo0r/react-native-push-notification (Free)

First start with installing "messaging" module.

npm install --save @react-native-firebase/messaging

Next import the messaging module into the component.

import messaging from '@react-native-firebase/messaging';

For iOS add the following line to App.js as we need to explicitly register with APNs

messaging().registerDeviceForRemoteMessages();

These are some functions present in messaging module:

1. deleteToken()
2. getAPNSToken()
3. getinitialNotification()
4. getToken()
5. hasPermission()
6. requestPermission()
7. onTokenRefresh()

Crashlytics

Install the "crashlytics" firebase module.

npm install --save @react-native-firebase/crashlytics

For further additional installation check the given links below:

Android Setup

iOS Setup

Note: Crashlytics by default does not record crashes in debug mode. To enable it create a firebase.json file in root directory of the project with following configuration:

{
  "react-native": {
    "crashlytics_debug_enabled": true
  }
}

After completion of your installation you can force a crash using the following line:

crashlytics().crash();

You will see a crash record in your firebase crashlytics console.

Realtime Database

Install the realtime database module.

npm install --save @react-native-firebase/database

You can create a reference object of the database object

database().ref('dbLink')

To setup an active listener call the "on" method with an event handler.

database()
  .ref('dbLink')
  .on('value', snapshot => {
    console.log('User data: ', snapshot.val());
  });

You can perform CRUD operations using this module.
