// These rules grant access to a node matching the authenticated  
// user’s ID from the Firebase auth token  
{  
“rules”: {  
“users”: {  
"$uid": {  
".read": “$uid === auth.uid”,  
".write": “$uid === auth.uid”  
}  
}  
}  
}

This doesnt grant a user permission to read or write? However, I would like each user to have their own Node, any help would be great thanks

You’re better off learning the Firestore rules, unless you have a special reason you need Firebase.

Hi  
sorry about that.

I meant to say your firebase rules suggestion suffices to write user node specific data.

And after I read through Firestore, the day before yesterday, I think @AaronSterling has the best suggestion for you, unless you don’t like the Beta-ness of Firestore.

I reckon Google is going to abandon Firebase over Firestore because it is just the next level of it.

I am going to prefer Firestore of Firebase anyway

Hi,

Hope you’re well.

I have now changed over to Firestore but I am still unser after reading how to save by a unique userId?

Any help would be appreciated, thank you.

Hi

something like

`db.collection('users').doc(uid).set({stuff:'data'})`

Where uid is the uid you collect from the authentication steps.

With rules setup as per documentation:

```auto
// Grants a user access to a document matching their Auth user Id
service cloud.firestore {
  match /databases/{database}/documents {
    // Collection named "users", document named after the userId
    match /users/{userId} {
      allow read, write: if request.auth.uid == userId;
    }
  }
}

```

Not tried it myself, but i guess this should be about it

Just give it a try and read the docs
