[FIXED] How to add custom key for firebase realtime database?

Issue

How to add custom key for firebase realtime database? I'm using react native fetch api to connect with database.

fetch('https://chld-43c34.firebaseio.com/players.json?auth='+token,{
            method: 'POST',         
            body: JSON.stringify( playerData,)     
            }

I have user id in a variable 'userId',want to add that as the key.

Solution

When you use method: 'POST' the database generates a unique child key for you. To instead write the data directly to the location you specify, use method: 'PUT' and pass the exact location in the URL:

let playerid = 'your_player_id';
fetch(`https://chld-43c34.firebaseio.com/players/${playerid}.json?auth=${token}`,{
    method: 'PUT',         
    body: JSON.stringify( playerData,)     
}
