You can update the data in Cloud Firestore with 2 methods:
set() and update(). The difference is, set() will overwrite the whole document.update()will update only certain fields that need to be updated. Let's check both of the approaches for updating your Firestore data.set()const doc = await firebase.firestore().collection('collectionName').doc('docID').set({
docField: newFieldValue
});
In case you do not want to overwrite your data, you can add
merge: true to your code, so that you only update the required fieldsupdate()For the update() method, type in the below Code:
const doc = await firebase.firestore().collection('collectionName').doc('docID').update({
docField: newFieldValue
});
