How to put an object inside another object in firebase database programmatically?

Question

I'm setting up a firebase database for handling some requests I receive from my application. I need to insert an object "player" inside another object "room" to handle the multiplayer lobbies.

For a better comprehension I also do a little schema using firebase realtime db - schema below.

I want that instead of "room 1" the database puts an unique id, same thing for "player 1" and the other. Do you have any advice to help me doing this?

Try this (using a "path" to point to where you need):

const updates = {}
const roomName = 'room1'
const playerName = 'player1'
const path = `chip-chop/rooms/${roomName}/${playerName}`
const playerData = {
  name: 'marco',
  points: 0,
}
updates[path] = playerData
await firebase.database().ref().update(updates)

Please note that this will update the data. This means that other fields will not be affected (whether that is a bad or good thing is up to you)
