How to Displaying logged email in firebase?

Question

I have the code right here:

But how to display ALL the created account?

Answer 1

Interesting question. Let me try before Burey or Martin answers your question.

1. If users data are general data, the way is something similar to this :

const getInfo = () => {
read("users", data=>{
for(let email in data.val()) {
document.body.innerHTML += "<br/>"+ email;
}
});
};

But not sure, I checked Martin's script on Dropbox and made some edits based on guessing. Seems it works only if you upload the user data in specific format : "email/"+email+"pass/"+pass;

2. For the auth() methods, let me try to dig into the firebase doc 😋

Reference:

https://firebase.google.com/docs/auth/android/password-auth

Seems there is a getCurrentUser() method, but no method for client to see all registered email (otherwise too malicious, isn't it?)

Answer 2

You cannot just display all accounts only using auth as far as I know, you would need to store the data you want using firebase database. And the just query it, like Gordon said.

auth.createUserWithEmailAndPassword(email, password).then(function() {
firebase.database.ref("Users/"+auth.currentUser.uid).set({
email: email, // or whatever data you want to store
});

When all is stored you can just call

firebase.database.ref("Users").once(function(v) {
for(var uid in v.val())
console.log(JSON.stringify(v.val()[uid],nulll,4);
});

-> I had a code doing the exact same thing but I deleted it sorry 😅
