I have an array stored in my firebase database, structured like this:
matches:[ {match:{id:1,data:...}}]
I am looking for a way to update just one specific item within this array. Let's say I want to locate the match with the ID of 32 and modify its data. However, I believe the current method I am using is not efficient. It involves retrieving the entire array from firebase, making the necessary changes, and then saving the entire array back to the database.
const ref = `/users/${currentUser.uid}/matches`;
var list = [];
firebase.database().ref(ref).on('value', function (snap) { list = snap.val(); });
if (list.length > 0) {
const indexToUpdate = list.findIndex(k => k.name == match.name)
if (indexToUpdate >= 0) {
list[indexToUpdate] = match;
return dispatch => {
firebase
.database()
.ref(`/users/${currentUser.uid}/matches`)
.set(list)
.then(() => {
dispatch({ type: MATCH_UPDATE, payload: match });
});
};
}
}
Is there a better way to achieve this? Any suggestions would be greatly appreciated.
