As I work on my AngularJS and Firebase-powered website project, I aim to leverage Facebook login for seamless user connectivity. While Firebase's simple login feature promises an easier authentication process, I face the challenge of effectively accessing logged-in user info across various sections of my webpage.
Initially, I coded:
var userInfo = null;
var ref = new Firebase('https://<yourfirebase>.firebaseIO.com/');
var auth = new FirebaseSimpleLogin(ref, function(error, user) {
if(error)
alert("You are not logged in");
else if(user)
{
//store userinfo in variable
userInfo = user;
}
else
//user logged out
});
//do something with userInfo
alert(userInfo.name);
I attempted to execute this script at the page's top and utilize the user data. However, encountering issues where code referencing `userInfo` (e.g., in the alert) would always run prior to `userInfo` being populated led me to recalibrate my approach.
Subsequently, I found myself creating a fresh Firebasesimplelogin object each time I needed user information—an unsustainable practice. Each instance triggered whenever subsequent calls or user logouts occurred.
Hence, my query centers on optimizing FirebaseSimpleLogin usage for efficient utilization of user details. Ideally, features like `getUserInfo()` or `isLoggedIn()` functions could streamline this process. How can this be accomplished effectively?
