I'm developing an app using React Native and Firebase RealTime database.
I want to do the following. I want to create a data tree like following.
myRoot
|
|---myKey: "myValue"
But here, I DON'T want to do it as follows.
foo = async () => {
let myRef = firebase.database().ref('myRoot');
await myRef.set({
myKey: "myValue"
})
}
Instead, I want to do something like this.
writeData = async (key, value) => {
let myRef = firebase.database().ref('myRoot');
await myRef.set({
key: value
})
}
And, then call the function to add data.
this.writeData(myKey, myValue);
For example, after I called the function as below,
this.writeData("myFirstKey", "myFirstValue");
this.writeData("mySecondKey", "mySecondValue");
this.writeData("myThirdKey", "myThirdValue");
I need the output as below.
myRoot
|
|---myFirstKey: "myFirstValue"
|---mySecondKey: "mySecondValue"
|---myThirdKey: "myThirdValue"
How to do this?
Calling set on a given object will replace it completely instead of set you can use update function like this
writeData = async (key, value) => {
let myRef = firebase.database().ref('myRoot');
await myRef.update({
key:value
})
}
Yes.. I got the point..
writeData = async (key, value) => {
let myRef = firebase.database().ref('myRoot');
await myRef.child(key).set(value);
}
