const firebaseConfig = {

  authDomain: "YOUR_AUTH_DOMAIN",
  databaseURL: "YOUR_DATABASE_URL",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_STORAGE_BUCKET",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID"
};

firebase.initializeApp(firebaseConfig);

const database = firebase.database();
const ref = database.ref("users");

// 删除名为"nodeToDelete"的节点
ref.child("nodeToDelete").remove()
  .then(() => {
    console.log("节点删除成功");
  })
  .catch((error) => {
    console.error("节点删除失败：", error);
  });
