Firebase how can I add a child node with a given name?

Question

If I have a /users folder on Firebase realtime db, with inside various UID , how can I add a child called /history under an UID ?

Using .child('users').child(UID).push() it creates a unique id, I'd like it to be called "history" instead, how can I achieve it?

Answer 1

Calling push() generates a new unique location under the reference on which you call it. To instead control the key of the location you write to. use child :

ref.child('users').child(UID).child("history").set("hello")

If you'd instead want to create a new unique child node under the history node, you'd do:

ref.child('users').child(UID).child("history").push("hello")
