Firebase Auth SDK

A lightweight TypeScript wrapper for Firebase Authentication REST API. This package provides a simple interface to interact with Firebase Authentication services without the full Firebase SDK dependency.

Installation

npm install firebase-auth-sdk

Features

• User authentication (sign up, sign in)
• Token management (refresh tokens, validate tokens)
• Profile management
• Password reset functionality
• Authentication state verification

Usage

import { FirebaseAuthSDK } from "firebase-auth-sdk";

const auth = new FirebaseAuthSDK("your-api-key");

Sign Up

const signUp = async () => {
  try {
    const user = await auth.signUp("[e-mail]", "password123");
    console.log("User created:", user.localId);
  } catch (error) {
    console.error("Sign up failed:", error.message);
  }
};

Sign In

const signIn = async () => {
  try {
    const user = await auth.signIn("[e-mail]", "password123");
    console.log("Signed in:", user.idToken);
  } catch (error) {
    console.error("Sign in failed:", error.message);
  }
};

Email Verification

const sendVerification = async (idToken: string) => {
  try {
    await auth.sendEmailVerification(idToken);
    console.log("Verification email sent");
  } catch (error) {
    console.error("Failed to send verification:", error.message);
  }
};

// When user clicks verification link, verify the OOB code
const verifyEmail = async (oobCode: string) => {
  try {
    await auth.confirmEmailVerification(oobCode);
    console.log("Email verified successfully");
  } catch (error) {
    console.error("Email verification failed:", error.message);
  }
};

Password Reset

const resetPassword = async () => {
  try {
    // Send reset email
    await auth.sendPasswordReset("[e-mail]");
    console.log("Password reset email sent");

    // When user clicks reset link, verify the OOB code and set new password
    const oobCode = "code-from-email";
    await auth.verifyPasswordReset(oobCode, "newPassword123");
    console.log("Password reset successful");
  } catch (error) {
    console.error("Password reset failed:", error.message);
  }
};
