In multi-client development, consistent authentication isn't just nice-to-have—it's non-negotiable for security and maintainability. After implementing the same auth logic across dozens of projects, we standardized our approach with a single useAuth hook that handles:
🎯 What This Hook Solves:
Token lifecycle management (auto-refresh, expiration handling)
Cross-platform session handling (web, mobile, desktop)
Role-based access control (permissions, user roles)
Secure storage abstraction (localStorage, secure cookies, async storage)
🚀 The Result?
60% faster authentication implementation across new projects while significantly strengthening our security posture.
💻 The Code: A Production-Ready useAuth Hook
import { useState, useEffect, useCallback } from 'react';
// 🎯 Professional useAuth Hook
export const useAuth = () => {
const [user, setUser] = useState(null);
const [loading, setLoading] = useState(true);
const login = useCallback(async (email, password) => {
try {
const userData = await authService.login(email, password);
setUser(userData);
localStorage.setItem('token', userData.token);
return { success: true };
} catch (error) {
return { success: false, error: error.message };
}
}, []);
const logout = useCallback(() => {
setUser(null);
localStorage.removeItem('token');
}, []);
useEffect(() => {
// Check existing auth on mount
const token = localStorage.getItem('token');
if (token) {
authService.verifyToken(token).then(setUser).finally(() => setLoading(false));
} else {
setLoading(false);
}
}, []);
return { user, login, logout, loading };
};
// 💡 Usage in any component:
// const { user, login, logout } = useAuth();
