如何从浏览器控制台隔离firebase变量

(function() {
  // 这里声明 Firebase 变量
  const firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_AUTH_DOMAIN",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_STORAGE_BUCKET",
    messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
    appId: "YOUR_APP_ID"
  };

  // 初始化 Firebase
  firebase.initializeApp(firebaseConfig);

  // 其他 Firebase 相关的操作
  const db = firebase.database();
  const auth = firebase.auth();

  // 将 Firebase 实例暴露给外部，如果需要的话
  window.myFirebaseApp = {
    db,
    auth
  };
})();

// firebaseModule.js
export const initializeFirebase = () => {
  const firebaseConfig = {
    apiKey: "YOUR_API_KEY",
    authDomain: "YOUR_AUTH_DOMAIN",
    projectId: "YOUR_PROJECT_ID",
    storageBucket: "YOUR_STORAGE_BUCKET",
    messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
    appId: "YOUR_APP_ID"
  };

  firebase.initializeApp(firebaseConfig);
  return firebase;
};

export const getDatabase = () => firebase.database();
export const getAuth = () => firebase.auth();

import { initializeFirebase, getDatabase, getAuth } from './firebaseModule.js';

const firebase = initializeFirebase();
const db = getDatabase();
const auth = getAuth();
