如何使用Firebase身份验证登录用户

Question

I'm currently using firebase-admin to create a web Dashboard with node.js as a backend which will have multiple users and those users have user specific data in my database, note that I need them to be able to delete or add stuff to the database as well, I've managed to add new users to Autentication using firebase.auth().createUser() programmatically, but how would one go about logging in a user, and then from there controlling which uid is logged in and displaying his data (giving him access to the correct data, obviously don't want him messing with someone elses data).

I know this might seem like a really newbie question, and it probably is, but firebase docs always get me confused for some reason. Any tips? I'd greatly appreciate.

Any questions don't hesitate.

To login a new user, try this:

firebase.auth().signInWithEmailAndPassword(email, password)

this returns a Firebase.Promise which you can use to track the operation progress. If successful, it will return the corresponding Firebase.User object.

From there, the logged-in user will also be available in the firebase.auth().currentUser property. You can then use the user's uid property as a key for his JSON branch on the database.
