What is the best location to initialize Firebase in a React Native application?

What is the best way to initialize Firebase in a React Native project and how can I ensure that it is accessible throughout the entire project?

Below is my project structure for reference:

Project Structure

Here is a basic template for initializing Firebase:

// Initialize Firebase
const firebaseConfig = {
  apiKey: "api-key",
  authDomain: "project-id.firebaseapp.com",
  databaseURL: "https://project-id.firebaseio.com",
  projectId: "project-id",
  storageBucket: "project-id.appspot.com",
  messagingSenderId: "sender-id",
  appId: "app-id",
  measurementId: "G-measurement-id"
};

firebase.initializeApp(firebaseConfig); //How should I ensure access throughout the project?

Answer №1

Pick a file that will run only once and remains unaffected by any react re-renders... I recommend using Main.js for instance (or you can create a new file specifically for importing and exporting from firebase).

To access the initialized firebase instance, make sure to export it from the file after initialization.

export const firebaseInstance = firebase;
