Usage

Basic Login/Logout

import {
  login,
  logout,
  isLoggedIn,
  getUserProfile,
} from "react-native-amazon-login";

// Login
const handleLogin = async () => {
  try {
    const userProfile = await login();
    console.log("User:", userProfile);
    // { userId, name, email, postalCode, accessToken }
  } catch (error) {
    console.error("Login failed:", error);
  }
};

// Logout
const handleLogout = async () => {
  try {
    await logout();
    console.log("Logged out");
  } catch (error) {
    console.error("Logout failed:", error);
  }
};

// Check login status
const loggedIn = isLoggedIn();

// Get user profile
const profile = await getUserProfile();

Event Listeners

import {
  addLoginSuccessListener,
  addLoginFailureListener,
  addLogoutListener,
} from "react-native-amazon-login";

// Listen for login success
const successSubscription = addLoginSuccessListener((userData) => {
  console.log("Login successful:", userData);
});

// Listen for login failure
const failureSubscription = addLoginFailureListener((error) => {
  console.error("Login failed:", error);
});

// Listen for logout
const logoutSubscription = addLogoutListener(() => {
  console.log("User logged out");
});

// Clean up
successSubscription.remove();
failureSubscription.remove();
logoutSubscription.remove();
