I presented how we're using Firebase at Boiler Room at the first Firebase Berlin Meetup in September 2014.

1. @productgang @boilerroomtv

2. A custom chat for Boiler Room

6. AngularFire
JWT

8. Date mess-up thanks to using client local time

9. comment.date = Firebase.ServerValue.TIMESTAMP;
// FTW!

10. Moderators could delete single comments but
we also needed a way to ban users..

13. var until = Date.now() + ($scope.ban.timeframe * 60 * 1000);
commentsRef.root().child('banned_users/' + $scope.ban.uid).set(until);

14. "uid": {
".validate": "!root.child('banned_users').child(auth.id).exists()"
}
Validation Rules

15. child() expects a string argument.

16. "uid": {
".validate": "!root.child('banned_users').child(auth.id + '').exists()"
}
Validation Rules

17. var setBannedUsers = function(snap) {
bannedUsers = snap.val();
};
var checkBannedUsers = function() {
var time = Date.now();
for(bannedUser in bannedUsers) {
if(bannedUsers[bannedUser] < time) {
rootRef.child('banned_users/' + bannedUser).remove();
}
}
}
rootRef.child('banned_users').on('value', setBannedUsers);
setInterval(checkBannedUsers, 10000);

18. Thank you.
