    Very concise tutorial

  13. Maarten Berkenbosch says:

    PLEASE, is there any decent documentation on orderByChild and equalTo(). Every article or post I read on the internet about this, makes it even more confusing.
    I just can't believe that this is the answer to getting lists sorted in the GUI on the client side

    ref.child("users").orderByChild('last_update').on("value", function (snapshot) {
    snapshot.forEach(function(child) {
    console.log(child.val()) // NOW THE CHILDREN PRINT IN ORDER

    how to get data from a nested child that has unique id?

    for example: Users -> (random uid from firebase) -> History -> (random uid from firebase again) -> (result, score, date, time)

    how to get the data from this structure? help please!!

  54. Himanshu MS says:

    How get set child key = current user uid at SAME TIME as user REGISTER his account

    I did following –
    var userId = firebase.auth().currentUser.uid

    firebase.database().ref("users/" + userId).set({
    username: uname,
    password: passw

    But it's not working properly, it creates new entry in database for that user BUT the uid is of previously registered user, not current one!
    This is really pissing me off!
