The firekitAuth service provides methods for handling user authentication in your Svelte application. It includes support for Google authentication, email/password authentication, and user profile management.

Usage

import { firekitAuth } from 'svelte-firekit';

Methods

Google Authentication

await firekitAuth.signInWithGoogle()

Signs in a user using Google OAuth. Automatically creates/updates the user’s Firestore profile.

Email/Password Authentication

await firekitAuth.signInWithEmail(email: string, password: string)

Signs in a user with email and password.

await firekitAuth.registerWithEmail(
  email: string, 
  password: string, 
  displayName: string
)

Registers a new user with email and password. Automatically sends email verification and creates a Firestore profile.

User Management

await firekitAuth.logOut()

Signs out the current user.

await firekitAuth.sendPasswordReset(email: string)

Sends a password reset email to the specified address.

await firekitAuth.sendEmailVerificationToUser()

Sends an email verification to the current user.

await firekitAuth.updateUserProfile({
  displayName?: string,
  photoURL?: string
})

Updates the current user’s profile information.

await firekitAuth.updateUserPassword(
  newPassword: string, 
  currentPassword: string
)

Updates the user’s password. Returns a response object:

success: boolean
message: string
code?: string (in case of error)

await firekitAuth.deleteUserAccount()

Deletes the current user’s account and associated Firestore data. Returns:

success: boolean
message: string

Example

// In your Svelte component
async function handleSignIn() {
  try {
    // Sign in with Google
    await firekitAuth.signInWithGoogle();
    
    // Or with email/password
    await firekitAuth.signInWithEmail('[email protected]', 'password');
  } catch (error) {
    console.error('Authentication failed:', error);
  }
}

async function handlePasswordUpdate() {
  const result = await firekitAuth.updateUserPassword(
    'newPassword123', 
    'currentPassword'
  );
  
  if (result.success) {
    console.log(result.message);
  } else {
    console.error(result.message);
  }
}

Notes

All authentication methods automatically sync user data with Firestore
Email verification is sent automatically on new user registration
User profile updates are automatically synced with Firestore
Password updates require reauthentication with current password
Account deletion removes both authentication and Firestore data
