    Hi, I’ve just been looking through the Firebase plugin docs. Looks great and simple to use as always.

    Can I ask what is the recommended way to delete a key from the database.

    How would I remove a user if the data is structured like in the example:

      "public" : {
        "news" : "Firebase Plugin is now live!"
      "users" : {
        "<user-id>" : {
         "username" : "John Doe",
         "age" : 22,
         "motto" : "Felgo is awesome!"

    Hi Alb,

    the Firebase documentation definitely needs some more examples đŸ™‚ You can use a path to access your keys, this is shortly demonstrated in this example, but we’ll also add it to the API documentation of the database item.

    // you can try
    firebaseDb.setValue("users/<user-id>", undefined);
    // or
    firebaseDb.setValue("users/<user-id>", null);

    Then you can check if a key is defined. Maybe it’s even better to introduce an own “deleted” property and set this one instead so you don’t lose the data and can possibly restore it.

    Hope that helps!




    Thanks for your quick reply. Great idea for retrieving data too.
