Initialize Firebase App

This feature allows you to initialize a Firebase app with a given configuration. The configuration object contains various keys required to connect to your Firebase project.

const firebaseConfig = {
  apiKey: "your-api-key",
  authDomain: "your-auth-domain",
  projectId: "your-project-id",
  storageBucket: "your-storage-bucket",
  messagingSenderId: "your-messaging-sender-id",
  appId: "your-app-id"
};

const app = firebase.initializeApp(firebaseConfig);

Access Firebase Services

Once the Firebase app is initialized, you can access various Firebase services like Authentication and Firestore using the app instance.

const auth = app.auth();
const firestore = app.firestore();

Type Safety with TypeScript

The package provides TypeScript type definitions, ensuring type safety and better development experience when working with Firebase services.

import { FirebaseApp } from '@firebase/app-types';

const app: FirebaseApp = firebase.initializeApp(firebaseConfig);
