我正在尝试初始化 Firebase 应用程序,但我不明白如何或在哪里调用它。
我有一个文件名 fire.tsx ,其中有一个对 firebase 的调用initializeApp。但现在怎么办?我如何将其包含在我的应用程序中?
我认为只需添加import { firebaseApp, firebaseAnalytics } from './fire';到 App.tsx 的顶部就可以工作,但显然不行。我这样做错了吗?
import firebase from "firebase";
import "firebase/auth";
import { initializeApp } from "firebase/app";
import { getAnalytics } from "firebase/analytics";
const firebaseConfig = {
apiKey: "xxx-xx-xx",
authDomain: "xxx-xx-xx",
databaseURL: "xxx-xx-xx",
projectId: "xxx-xx-xx",
storageBucket: "xxx-xx-xx",
messagingSenderId: "xxx-xx-xx",
appId: "xxx-xx-xx",
measurementId: "xxx-xx-xx"
};
const firebaseApp = initializeApp(firebaseConfig);
export default firebaseApp;
export const firebaseAuth = firebase.auth();
export const firebaseAnalytics = getAnalytics();

仅使用新的模块化 SDK,因为兼容版本将在未来的更新中删除。尝试这样重构代码:
import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";
import { getAnalytics } from "firebase/analytics";
const firebaseConfig = {
apiKey: "xxx-xx-xx",
authDomain: "xxx-xx-xx",
databaseURL: "xxx-xx-xx",
projectId: "xxx-xx-xx",
storageBucket: "xxx-xx-xx",
messagingSenderId: "xxx-xx-xx",
appId: "xxx-xx-xx",
measurementId: "xxx-xx-xx"
};
const firebaseApp = initializeApp(firebaseConfig);
export const firebaseAuth = getAuth(firebaseApp);
export const firebaseAnalytics = getAnalytics(firebaseApp);

新的模块化 SDK 会检查是否已创建默认实例,因此您不必像以前的版本一样。
