我需要将firebase数据索引到algolia，firebase中的读写规则都需要身份验证(auth!=null)

// Firebase身份验证配置示例
firebase.auth().signInWithEmailAndPassword(email, password)
  .then((userCredential) => {
    // 用户登录成功
  })
  .catch((error) => {
    // 处理错误
  });

{
  "rules": {
    ".read": "auth != null",
    ".write": "auth != null"
  }
}

const admin = require('firebase-admin');
const algoliasearch = require('algoliasearch');

admin.initializeApp();
const db = admin.firestore();
const algoliaClient = algoliasearch('YOUR_ALGOLIA_APP_ID', 'YOUR_ALGOLIA_ADMIN_API_KEY');
const index = algoliaClient.initIndex('your_index_name');

db.collection('your_collection_name').onSnapshot((snapshot) => {
  snapshot.docChanges().forEach((change) => {
    if (change.type === 'added') {
      index.saveObject(change.doc.data());
    }
    if (change.type === 'modified') {
      index.saveObject(change.doc.data());
    }
    if (change.type === 'removed') {
      index.deleteObject(change.doc.id);
    }
  });
});
