How to properly delay a guard until angular knows the definitive session state

Angular 19

Hi, I have been playing around learning how to protect some routes with authentication

my problem is that the user state takes a moment to properly notify the final resolution

meaning that, if a user is authenticated and access to a protected route, the user state returns null and then the user, breaking the protection

I have been trying different techniques like BehaviorSubject and filtering the undefined state to know that firebase still didn't provide a final state

I have also found a guy getting the session from the cookies https://medium.com/@ignatovich.dm/securing-angular-applications-with-route-guards-and-firebase-auth-54c02bdd4811 it is sync and with a straight answer

if I could find some examples for these use cases I will appreciate !

未指定文件、测试或入口点；该 issue 要求提供有关如何延迟 Angular route guards，直到 Firebase 身份验证完成解析的指导。首先明确 AngularFire API 或示例的预期范围，然后记录一个可复现的已认证路由示例，并验证在未解析状态期间不会发生重定向。
