@firebase/auth-compat

What is @firebase/auth-compat?

The @firebase/auth-compat package is a compatibility layer for Firebase Authentication in the Firebase JavaScript SDK. It allows developers to use the new Modular SDK with the same API surface as the older Namespaced SDK, facilitating easier migration and compatibility with existing codebases.

What are @firebase/auth-compat's main functionalities?

User Authentication

This feature allows developers to authenticate users using their email and password. The provided code demonstrates how to sign in a user and handle any errors that might occur during the process.

firebase.auth().signInWithEmailAndPassword(email, password).then((userCredential) => { var user = userCredential.user; }).catch((error) => { var errorCode = error.code; var errorMessage = error.message; });

Social Authentication

This feature enables authentication using social providers like Google, Facebook, etc. The code sample shows how to authenticate a user using Google as the social provider through a popup method.

var provider = new firebase.auth.GoogleAuthProvider(); firebase.auth().signInWithPopup(provider).then((result) => { var credential = result.credential; var user = result.user; }).catch((error) => { var errorCode = error.code; var errorMessage = error.message; });

User Management

This feature allows for the creation of new user accounts with an email and password. The code demonstrates how to create a user and handle potential errors.

firebase.auth().createUserWithEmailAndPassword(email, password).then((userCredential) => { var user = userCredential.user; }).catch((error) => { var errorCode = error.code; var errorMessage = error.message; });

Other packages similar to @firebase/auth-compat

firebase-auth

This package provides authentication services similar to @firebase/auth-compat but is designed for use with the older Firebase SDK. It lacks the modular approach of the newer SDK versions, making it less flexible in terms of tree shaking and bundle size optimization.

react-firebase-hooks

While primarily a set of hooks for Firebase, this package includes hooks for Firebase Authentication, offering a more React-centric approach to handling Firebase auth in React applications compared to @firebase/auth-compat.
