Append to an arary field in Firestore

Question

I\'m using Firebase and Vuejs to create an database element, which has object array inside.

That\'s how the object looks, and I want to add tasks through the form

Answer 1

You can append an item to an array using FieldValue.arrayUnion() as described in the documentation. For example:

// Atomically add a new region to the "regions" array field.
washingtonRef.update({
    regions: firebase.firestore.FieldValue.arrayUnion("greater_virginia")
});
