VisualizaçõesHow to make separate login for Users and Freelancer based on Roles that is in my real time database Firebase
Hello I am working a web application with Firebase Realtime Database and Authentication with nodejs or javascript.
This is my real time database and I want to make a login form which if the User = User he will go to User Index and if the User = Freelancer he will go to Freelancer Index.
And this is the line of code that I was tweaking or trying but It doesn't go in my way.
<script>
firebase.auth().onAuthStateChanged(function(user)
{
if(user)
{
var userID = firebase.auth().currentUser.uid;
firebase.database().ref('Users/' + userID).once('value').then(function(snapshot)
{
if (snapshot.val())
{
window.location.href = "index.html";
}
else
{
window.location.href = "okay.html";
}
});
}
});
</script>
Hoping I can get feedbacks or answers here. I am almost trying it for 2days already that's why I seek help here. Comments and answers are highly appreciated thank you!

With your current data structure you will need to check in two places to determine what role a user has. While this technically possible, it is less efficient and more complex in code.
I recommend instead to store a single top-level node (say UserRoles) where you simply keep the role for each UID:
"UserRoles": {
"uidOfUser1": "Freelancer",
"uidOfUser2": "User"
}
With that in place, you can load it in your onAuthStateChanged callback with:
const ref = firebase.database.ref("UserRoles");
ref.child(user.uid).once("value").then((snapshot) => {
if (snapshot.val() === "Freelancer") {
window.location.href = "okay.html";
}
else if (snapshot.val() === "User") {
window.location.href = "index.html";
}
else {
alert("Can't determine role for user: "+user.uid)
}
});
