Firebase - Detaching Callbacks

This simple chapter will show you how to detach callbacks in Firebase.

Detach Callback for Event Type

Let's say we want to detach callback for a function with value event type.

Example

var playersRef = firebase.database().ref("players/");

ref.on("value", function(data) {
   console.log(data.val());
}, function (error) {
   console.log("Error: " + error.code);
});
We need to use off() method. This will remove all callbacks with value event type.
playersRef.off("value");

Detach All Callbacks

When we want to detach all callbacks, we can use −
playersRef.off();
