Firebase - Write Data
In this chapter, we will show you how to save your data to Firebase.
Set
The set method will write or replace data on a specified path. Let us create a reference to the player’s collection and set two players.
var playersRef = firebase.database().ref("players/"); playersRef.set ({ John: { number: 1, age: 30 }, Amanda: { number: 2, age: 20 } });
We will see the following result.
Update
We can update the Firebase data in a similar fashion. Notice how we are using the players/john path.
var johnRef = firebase.database().ref("players/John"); johnRef.update ({ "number": 10 });
When we refresh our app, we can see that the Firebase data is updating.
