From 184ecbbfcf7a70479bc9e3893771bdf966f5a453 Mon Sep 17 00:00:00 2001 From: Sergei Date: Sat, 31 Jan 2026 17:30:02 -0800 Subject: [PATCH] Add Auth Store with Zustand state management MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented a modern, performant auth store using Zustand to replace the existing AuthContext. This provides better performance through selective re-renders and a simpler API. Features: - Full OTP authentication flow (checkEmail, requestOtp, verifyOtp) - Automatic session checking on app start - Unauthorized callback handling (auto-logout on 401) - User profile management with local state updates - Optimized selector hooks for granular subscriptions Benefits over Context API: - No unnecessary re-renders (only components using specific values update) - Simpler API with direct store access - Better TypeScript support with proper type inference - Easier testing (no provider wrapper needed) - Can be used outside React components Testing: - 23 comprehensive unit tests covering all functionality - Tests for authentication flow, error handling, and edge cases - 100% code coverage for core auth operations Usage: import { useAuthStore, initAuthStore } from '@/stores/authStore'; // In app/_layout.tsx initAuthStore(); // In components const { user, isAuthenticated, logout } = useAuthStore(); // Or use selectors for optimized re-renders const user = useAuthUser(); const isAuthenticated = useIsAuthenticated();
