firebase How to use the Firebase Database to keep a list of Firebase Authentication users How to save user profile data
Example
Every authenticated user has a Firebase uid that's unique across all providers and is returned in the result of every authentication method.
A good way to store your user's data is to create a node to keep all the users's data and to protect it using your security rules
- Database
{
"users": {
"uid1" : {
"name": "Steve",
"surname": "Jobs"
},
"uid2" : {
"name": "Bill",
"surname": "Gates"
}
}
}
- Security
{
"rules": {
"users": {
"$uid": {
// If node's key matches the id of the auth user
".write": "$uid == auth.uid"
}
}
}
}
The $uid in the above rules is a so-called "dollar variable", which ensures that the rules under it are applied to all child nodes of users. For more information see the documentation on Using $ Variables to Capture Path Segments.
