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

admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  databaseURL: 'https://your-project-id.firebaseio.com'
});

const db = admin.firestore();

// 将新数据追加到数组中
const arrayRef = db.collection('your-collection').doc('your-document');
arrayRef.update({
  yourArrayField: admin.firestore.FieldValue.arrayUnion('newData')
})
.then(() => {
  console.log('数据已成功追加到数组中');
})
.catch((error) => {
  console.error('追加数据到数组时出错：', error);
});

import { Component } from '@angular/core';
import * as firebase from 'firebase/app';
import 'firebase/firestore';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.scss']
})
export class AppComponent {
  constructor() {
    const config = {
      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(config);
  }

  // 将新数据追加到数组中
  appendDataToArray() {
    const db = firebase.firestore();
    const arrayRef = db.collection('your-collection').doc('your-document');
    arrayRef.update({
      yourArrayField: firebase.firestore.FieldValue.arrayUnion('newData')
    })
    .then(() => {
      console.log('数据已成功追加到数组中');
    })
    .catch((error) => {
      console.error('追加数据到数组时出错：', error);
