Firebase child_added for new items only

Question

I am using Firebase and Node with Redux. I am loading all objects from a key as follows.

firebaseDb.child(\'invites\').on(\'child_added\', snapshot => {
}         


        

Answer 1

I solved this by ignoring child_added all together, and using just child_changed. The way I did this was to perform an update() on any items i needed to handle after pushing them to the database. This solution will depend on your needs, but one example is to update a timestamp key whenever you want the event triggered. For example:

var newObj = { ... }
// push the new item with no events
fb.push(newObj)
// update a timestamp key on the item to trigger child_changed
fb.update({ updated: yourTimeStamp })
