当我的Node.js应用程序离线时，我应该将Firebase数据库设置为离线吗？

const firebase = require('firebase/app');
require('firebase/database');

// 初始化Firebase
const firebaseConfig = {
  // ...您的Firebase配置
};

firebase.initializeApp(firebaseConfig);

// 启用离线数据持久化
const database = firebase.database();
database.ref().setPersistence(firebase.database().Persistence.LOCAL);

const firebase = require('firebase/app');
require('firebase/database');

const firebaseConfig = {
  apiKey: "YOUR_API_KEY",
  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();

// 启用离线持久化
database.ref().setPersistence(firebase.database().Persistence.LOCAL)
  .then(() => {
    console.log('离线持久化已启用');
    // 进行数据操作...
  })
  .catch((error) => {
    console.error('启用离线持久化失败:', error);
  });

// 写入数据
database.ref('users/123').set({
  name: 'John Doe',
  email: 'john.doe@example.com'
});

// 读取数据
database.ref('users/123').once('value')
  .then(snapshot => {
    console.log(snapshot.val());
  });
