Integrating Firebase in a React Native App


Firebase has emerged as a robust and flexible platform for building and managing various aspects of your mobile applications. In this guide, we’ll walk you through the process of integrating Firebase into your React Native app, covering both iOS and Android platforms.

Why Choose Firebase?

Firstly Firebase offers a suite of tools and services that simplify app development, including real-time database, authentication, storage, analytics, and more. Secondly Its ease of use and cross-platform compatibility make it an excellent choice for React Native projects.

Step 1: Setting Up Your React Native Firebase Project

Start by creating a new project on the Firebase Console. Follow the prompts to set up your project and enable the desired Firebase services.

Step 2: Installing Firebase Dependencies

In your React Native project directory, install the necessary Firebase dependencies using npm or yarn:

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

Step 3: Linking Dependencies (For React Native < 0.60)

If your React Native version is below 0.60, you’ll need to link the native modules:

react-native link @react-native-firebase/app

Step 4: Configure Firebase for Platforms

iOS Integration:

  1. Drag and drop the downloaded GoogleServices-Info.plist file into your Xcode project.
  2. In Xcode, open the project settings, select your target, and navigate to the “Info” tab.
  3. Add the bundle identifier from your Firebase project to your Xcode projects “Bundle Identifier.”
  4. Open your AppDelegate.m file located in ios/YourAppName folder and add the following code inside the application:didFinishLaunchingWithOptions: method:

Android Integration:

  1. Copy the downloaded google-services.json file into your android/app folder.
  2. Open the build.gradle file (located at android/build.gradle) and add the following inside the dependencies block:
  1. At the bottom of the build.gradle file (located at android/app/build.gradle) , add:

Step 5: Using Firebase Services

Let’s cover some common Firebase services integration.

Firebase Authentication:

Real-time Database:

import database from ‘@react-native-firebase/database’;

Cloud Firestore:

Step 6: Handling Push Notifications 

For push notifications, you can use Firebase Cloud Messaging (FCM) and react-native-firebase/messaging library. The setup involves additional configuration steps for both platforms.


– Configure APNs (Apple Push Notification service) certificates.

– Integrate the messaging module for handling FCM notifications.


– Set up a Firebase project for Android.

– Configure FCM settings in your Android project.

Firebase vs Other Cloud based Platforms: A Quick Comparison:

  • firebase vs azure: Firebase is a focused, user-friendly cloud platform for quick mobile and web app development, ideal for startups. Azure, a comprehensive and versatile cloud solution, caters to diverse enterprise needs, emphasizing scalability and an extensive service range. Choose Firebase in firebase vs azure for simplicity and speed or Azure for robust solutions tailored to larger-scale enterprise requirements.
  • Onesignal vs firebase: OneSignal excels in streamlined push notification and in-app messaging services, prioritizing simplicity and quick integration for enhanced user engagement. In contrast, Firebase is a comprehensive mobile and web development platform, encompassing a broader suite of services, including Firebase Cloud Messaging (FCM) for push notifications. Developers can choose OneSignal in onesignal vs firebase for a focused solution or opt for Firebase when seeking an all-encompassing platform for various app development needs.
  • Firebase with Ionic: Firebase and Ionic together offer a potent solution for mobile app development. With Firebase’s seamless backend services and Ionic’s cross-platform framework, developers can rapidly create scalable and visually appealing mobile applications. This dynamic combination ensures ease of use, real-time data sync, and efficient cross-platform development.


In conclusion Integrating Firebase into your React Native app provides a powerful set of tools to enhance user experience, manage data, and track analytics. By following the steps outlined in this guide, you’ll be well on your way to leveraging Firebase’s capabilities in your mobile application, both on iOS and Android platforms.
