// Initialize an instance of AuthService
AuthService.initialize(
    'your-firebase-project-id',

    'your-firebase-private-key',
    true, // Enable caching (default is true)
    { host: 'your-redis-host', port: 6379 }, // Redis connection parameters
    'your-firebase-database-url' // Optional: Firebase database URL
);
const authService = AuthService.getInstance()

Middleware usage

// Use the middleware in your Express route
app.get('/protected-route', authService.verifyMiddleware, (req, res) => {
    // Access protected resources here
    res.send('Authenticated user!');
});
