About Firebase

React Native Firebase is a brand that offers a comprehensive collection of packages designed to bring React Native support for all Firebase services on Android and iOS apps. To get started, you'll need to set up a Firebase project and install the app module. Before diving into the installation process, there are a few prerequisites. You should be familiar with creating a project with React Native and have an active Firebase project. If you need help with these prerequisites, the documentation provides links to guide you through the process. Once you've met the prerequisites, you can install React Native Firebase by following a few steps, including installing the NPM module and adding Firebase config files to your application. The installation process also includes specific setup steps for both Android and iOS apps. After successfully linking and rebuilding your project, your application will be connected to Firebase using the @react-native-firebase/app module. However, to utilize other Firebase services, you'll need to install the modules for each individual service separately. React Native Firebase simplifies the integration of Firebase services into your React Native apps, allowing you to leverage the powerful features Firebase has to offer.
