Firebase Firestore 適用於真實數據庫但不適用於模擬器

Question

我正在使用 Firebase 並開始嘗試使用 Firebase 模擬器運行本地開發實例。 我正在運行 Firebase 工具的 v8.4.1。 當我使用真正的 Firestore 數據庫運行時，一切正常。 但是，當我使用模擬器時出現了問題。

I can set a document and then get it through Javascript but nothing shows in the Firebase Emulators UI and the same in reverse, when I add data through the Firebase Emulators UI it isn't available using get in Javascript. 此外，當我使用 Firebase Tools CLI 的導入和導出 function 時，我通過 Javascript 添加的數據都沒有導出和導入。 我在瀏覽器控制台中沒有收到任何錯誤。

我不確定我在初始化 Firebase 或我缺少的其他配置時是否做錯了什么？

我正在運行： firebase emulators:start --only functions,firestore

Firebase 設置代碼

import * as firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/firestore';
import 'firebase/functions';

const db = firebase.initializeApp({
  apiKey: 'my_api_key',
  appId: 'my_app_id',
  authDomain: 'my_auth_domain',
  databaseURL: 'my_database_url',
  messagingSenderId: 'my_messaging_sender_id',
  projectId: 'my_project_id',
  storageBucket: 'my_storage_bucket',
}).firestore();

if (process.env.NODE_ENV === 'development') {
  firebase.setLogLevel('debug');

  db.settings({
    host: 'localhost:8000',
    ssl: false,
  });

  firebase.functions().useFunctionsEmulator('http://localhost:5001');
}

export { db };

Answer 1

原來問題是由於 Firebase 工具的當前狀態。 我以前一直在將 Firebase 工具與另一個項目一起使用，並且必須為我正在嘗試使用模擬器的當前項目運行use命令：

firebase use project_name

現在一切都按預期工作。
