如何在React中存储Firebase用户的uid？

Question

I'm working on a react web application where users can sign up with an email and a password. After signing up, each user will have access to their profile data. Below is a my firebase data structure:

users:{
   generatedUserUID:{
            name: "User1"
            profileImage: "http://via.placeholder.com/350x150"
            }
     }

What would be the best way to store the user's uid when the user is signed in so that it can be used throughout the project. Currently, I'm using the browser's localStorage, but I'm concerned that if the client browser doesn't support localStorage then the app will be rendered useless. So, I'm looking for an alternative and not have to depend on localStorage entirely. Any help is appreciated. Thank you.

Answer 1

You could use a library like Redux to manage data in your application. Redux helps you manage the state of your application.

Answer 2

The Firebase SDK can help out here. The currentUser property, accessed by firebase.auth().currentUser , gives you a User object containing the currently signed in user.

Check out the docs for more info.
