我如何使用 firebase 初始化我的应用程序

Question

am trying to initailize app in my firebase project but it not working instead am getting TypeError: Cannot read properties of undefined (reading 'apps'), please am i doing wrong here

this is my code import firebase from 'firebase/app';

const app = !firebase.apps.length 
  ? firebase.initializeApp(firebaseConfig)
  : firebase.app();

Answer 1

firebase.apps is not existing or is probably not defined

Try initializing firebase like this const app = firebase.initializeApp(firebaseConfig);

I got that from the official firebase documentation

Answer 2

use .getApps() instead of .apps
